Abstract

The invention provides a spinning reel for fishing, which can respond well to the action of a rocker arm when the rotation action is started and finished, and can stably rotate without generating large deformation of a rotor body when the arm part of a rotor is subjected to large force. Among the materials constituting the rotor, the rotor arm portion farther from the rotation shaft, or the rotor arm portion and the connecting portion are made of a material having a lower specific gravity than the material constituting the rotor main body closer to the rotation shaft, and the rotor main body is made of a material having a high rigidity.

Description

Spinning wheel type fishing reel for fishing

Technical Field

The present invention relates to a spinning reel for fishing, which winds a fishing line around a line cup that reciprocates in conjunction with a rotational operation of a swing arm by a line guide provided on a rotor that rotates in conjunction with the rotational operation of the swing arm, and more particularly, to a spinning reel for fishing, which reduces the weight of the rotor and improves the operability thereof.

Background

In general, a spinning reel for fishing includes a swing arm attached to a reel body, a rotor having a fishline guide, and a reel for winding a fishing line, and is configured such that when the swing arm is rotated, the rotor rotates in conjunction with the swing arm, the reel reciprocates in an axial direction of the reel, and the fishing line is wound around the reel through the guide. The rotor includes a cylindrical rotor body, first and second connecting portions extending radially outward from opposite positions of a rear end portion of the rotor body, and first and second rotor arms spaced apart from the rotor body from distal ends of the first and second connecting portions and extending forward (toward the cup) respectively, and is attached to the rotor body in a state in which the rotor is freely rotatable.

When a fish catches a fish, a large tension is generated in the fishing line when the fishing line is taken up through the swing arm or when the fishing line is released due to the sliding of the force release device, and the arm portion of the rotor is subjected to a large force inward in the radial direction. The force causes the entire rotor to deform, and when the deformation is large, the rotor arm interferes with the wire cup to block the rotation of the rotor. Therefore, the arm portion to which a large force is applied is required to have not only high bending strength and tensile strength but also small deformation of the rotor main body.

Further, since the above-described shape is complicated, there is a limit to a manufacturing method, a constituent material, and the like in order to save cost, and a conventional rotor is generally formed of a metal material and integrally molded by a casting method or the like.

On the other hand, in order to easily reduce the burden of holding a fishing tackle for a long time and to easily operate the fishing tackle, there is a strong demand for weight reduction of a fishing rod, a spinning reel for fishing, and the like (patent document 1).

Therefore, reduction in weight of the rotor constituting the spinning reel for fishing is also being studied, and a metal having a large specific gravity is replaced with a light metal or an alloy material thereof, a plastic material, a reinforced plastic material, or the like (patent documents 1 and 2).

Among these lightweight materials, if a rotor is made of a light metal or an alloy material thereof, the rotor can be made lightweight to some extent, and since the rotor is excellent in tensile strength and bending strength and strong in rigidity, the rotor can be made so that the entire rotor is not largely deformed even when the arm portion is subjected to a large force. Further, since the rotor can be integrally molded by a molding method or the like, there is an advantage that a relatively complicated rotor shape can be easily formed. Therefore, it is actually common to use a rotor integrally formed of a light metal such as a magnesium alloy or an aluminum alloy.

However, such a light metal rotor needs to be further improved in terms of the reactivity with respect to the rocker arm operating rotor at the start and end of the rotation operation.

On the other hand, if the rotor is formed of a material having a smaller specific gravity such as a plastic material or a reinforced plastic material, the weight can be further reduced, and therefore, the degree of reaction to the rocker operation at the start and end of the rotational operation of the rotor can be improved. In particular, when the rotor is formed using a fiber-reinforced plastic in which carbon fibers or the like are impregnated with a plastic, the rotor can be made to have a very high strength coefficient, a high tensile strength and a high bending strength as compared with the above-mentioned light metal, and a high degree of response to the rocker arm operation at the start and the end of the rotational operation.

However, these materials have low rigidity, and when the rotor arm portion receives a large force, the entire rotor is deformed, and even if the rotor arm portion interferes with the wire cup under the influence of the deformation, the rotational operation of the rotor is inhibited. Therefore, it is necessary to support the arm portion of the rotor by an arc-shaped reinforcing member or the like (patent document 3), which causes new problems such as entanglement and increase in inertia moment.

Further, although reinforced plastic materials, carbon fibers, and the like have extremely high tensile strength and bending strength, fibers are difficult to be oriented and molded, and when a rotor is produced from these materials, the rotor shape is not easily molded, and there is a problem that the production cost is easily increased.

Disclosure of Invention

[ problem to be solved by the invention ]

The present invention has been made in view of the above problems, and an object of the present invention is to provide a spinning reel for fishing that not only contributes to weight reduction of a fishing tackle, but also has high responsiveness to the movement of a rocker arm at the start and end of a spinning operation, and can stably perform the spinning operation without causing large deformation of a rotor body when a large force is applied to an arm portion of a rotor.

[ means for solving problems ]

In order to achieve the above object, the present inventors have focused on the fact that the moment of inertia is expressed substantially as the product of mass and diameter, and have proposed a rotor constructed from materials of different weights. That is, the rotor arm portion or the rotor arm portion and the connecting portion which are distant from the rotation shaft are formed of a material having a lower specific gravity than that of the material forming the rotor main body which is close to the rotation shaft among the materials forming the rotor, so that the moment of inertia can be effectively reduced, and the operability at the start and the end of the rotation operation can be improved. Further, by forming the rotor body from a material having high rigidity, when the arm portion of the rotor receives a large force, the deformation of the rotor body is small, and the rotation operation is not affected. The present invention is developed based on this idea.

That is, the present invention provides a spinning reel for fishing, comprising: the fishing reel comprises a fishing reel body, a rocker arm rotatably arranged on the fishing reel body, a line cup which is linked with the rotation of the rocker arm and reciprocates back and forth along a line cup shaft, and a rotor which is linked with the rotation of the rocker arm and rotates around the line cup shaft; the rotor is composed of a rotor main body with a generally cylindrical shape, a first connecting part and a second connecting part extending outward in the radial direction from 2 opposite positions of the rotor main body, a first rotor arm part and a second rotor arm part which are spaced from the rotor main body from the radial distal ends of the first connecting part and the second connecting part and extend forward (line cup side) respectively, and a fishing line can be wound on the line cup by a fishing line guide part mounted on one side of the rotor arm parts; the rotor body is formed of a metal material, and the first and second rotor arm portions are formed of a material having a lower specific gravity than the metal material.

In a preferred embodiment of the present invention, the metal material constituting the rotor body is an aluminum alloy such as a360 or the like, a magnesium alloy such as AZ91D or the like, and the material constituting the rotor arm portion is a fiber-reinforced material such as a glass fiber-reinforced plastic, a carbon fiber-reinforced material, a resin fiber-reinforced plastic or the like, or a magnesium alloy or the like.

In a preferred embodiment of the present invention, the first and second rotor arm portions are provided with: the distance from the second rotor arm portion to the bobbin axis (based on the shortest distance when the second rotor arm portion is not parallel to the bobbin axis) is shorter than the distance from the first rotor arm portion to the bobbin axis (based on the shortest distance when the second rotor arm portion is not parallel to the bobbin axis).

[ Effect of the invention ]

In the spinning reel for fishing according to the present invention, since the specific gravity of the material constituting the rotor arm portion at a position farther from the rotation axis is lower than that of the material constituting the rotor body at a position closer to the rotation axis, the moment of inertia of the rotor during rotation is effectively reduced, and the rotor sensitively reacts to the movement of the rocker arm at the start and end of rotation, thereby improving the operation sensitivity. In addition, the tension of the fishing line is sensitively changed, and the sensitivity of the fishhook is improved.

In the present invention, only the rotor arm portion can be formed of a reinforcing material, particularly a laminate of carbon fiber reinforcing materials, and the like, and it is not necessary to form a member having a complicated shape from these materials. Therefore, compared with the rotor integrally formed by using these materials, the rotor is simple to manufacture and the manufacturing cost is reduced.

Detailed Description

An embodiment of a spinning reel for fishing according to the present invention will be described below with reference to the accompanying drawings. In all of the present application, the axial direction means a direction along the cup axis, the rear means a side of the target member close to the reel body, and the front means a side of the target member close to the cup.

Fig. 1 schematically shows an entire external appearance of a spinning reel for fishing according to a typical embodiment of the present invention, and fig. 2 schematically shows a basic internal structure thereof. Fig. 3 shows an outline of a rotor according to an embodiment of the present invention, and is a plan view (a), a front view (B) (a view from an arrow a side of fig. 2 (a)), and a side view (a view from an arrow B of fig. 2 (a)).

As shown in fig. 1 and 2, in a typical embodiment of the present invention, a spinning reel for fishing includes a reel body 1, a swing arm 2 attached to the reel body, a rotor 3 fixed to be rotatable about a cup shaft 6, and a cup 5 fixed to the cup shaft 6, the rotor 3 rotates in conjunction with the rotation operation of the swing arm 2, the cup 5 reciprocates back and forth in the direction of the cup shaft 6, and when a stopper 25 attached to an arm portion of the rotor 3 is positioned at a fishing line receiving position, a fishing line 4 is drawn into a fishing line guide 24 attached to one side of the arm portion by the stopper 25, and the fishing line 4 is wound around the cup 5 through the fishing line guide 24.

As shown in fig. 2, in the fishing vessel body 1, a rocker arm shaft 2a to which a rocker arm 2 is attached is rotatably supported by a bearing, and a transmission mechanism that transmits the rotational operation of the rocker arm shaft 2a to a rotor 3 and a string cup 5 is provided.

As shown in fig. 2, a transmission mechanism that transmits the rotational operation of the rocker arm 2 to the rotor 3 generally includes: a drive gear 10 integrally mounted on the rocker shaft 2a, a cylindrical pinion gear 12 arranged along the direction of the cup bobbin 6; the drive gear 10 meshes with a pinion gear 12, the pinion gear 12 being fixed to the rotor 3. Thereby, the rotational motion of the rocker arm 2 is transmitted to the rotor 3 through the drive gear 10 and the pinion gear 12. Thus, with such a transmission mechanism, the weight and moment of inertia of the rotor 3 can affect the tactile sensation when operated by the rocker arm 2.

As shown in fig. 2, a transmission mechanism that transmits the rotational operation of the swing arm 2 to the wire cup 5 generally includes: a rocking gear 16 engaged with the reduction gear 15 integrally mounted on the rocker arm shaft 2a, and a slider 17 having a rocking groove 17a engaged with a projection 16a provided around the slider 17. The slider 17 is fixed to the bobbin shaft 6, and rotation of the swing gear 16 is converted into reciprocating motion of the bobbin shaft 6 by engagement of the protrusions 16a provided around the slider 17 with the swing grooves 17a, so that the bobbins 5 fixed to the bobbin shaft 6 are interlocked and reciprocated.

The reel 5 is normally provided between the first rotor arm portion 3a and the second rotor arm portion 3b of the rotor 3, and according to the above-described configuration, the reel 5 reciprocates back and forth along the reel shaft 6 while the rotor 3 rotates by rotating the operation rocker arm 2, and the fishing line 4 is wound around the winding groove 5a of the reel 5 through the fishing line guide 24 provided on the rotor 3.

As shown in fig. 3, the rotor 3 includes a substantially cylindrical (typically substantially cylindrical) rotor body 3e, first and

second connection portions

3c and 3d extending radially outward from positions facing each other on both sides of the rotor body 3e (typically near the rear end), and first and second

rotor arm portions

3a and 3b extending forward from ends of the first and

second connection portions

3c and 3d away from the rotor body 3e and spaced apart from the rotor body 3e (typically substantially parallel to the cylindrical rotor body 3 e).

As shown in fig. 3, the rotor body 3e is generally composed of a substantially cylindrical body portion 31 and a plate-like mounting portion 32 extending in a direction substantially orthogonal to the axial direction and fixed to the body portion 31, and an opening portion 32a is provided in the center of the mounting portion 32. The pinion gear 12 is inserted into the opening 32a and fixed to the rotor 3 by a fixing member 30 such as a nut. The pinion gear 12 is generally formed in an elongated cylindrical shape, and the cup shaft 6 penetrates the inside thereof, and a bearing is disposed on the inner peripheral surface of the pinion gear 12 so as to be spaced from the cup shaft 6 by a predetermined distance. In the embodiment shown in fig. 3, the bottom portion 31a of the substantially cylindrical body portion 31 is thicker than the other portions (31, 32) of the body portion 31, and among them, the connecting portion 31b with the first and second connecting

portions

3c, 3d is the thickest, so that the strength of the portion where stress is relatively easily concentrated becomes large in a concentrated manner.

As shown in fig. 1 to 3, the first and second connecting

portions

3c, 3d are generally provided so as to project radially outward from positions facing the outer peripheral surface of the substantially cylindrical body portion 31 of the rotor body 3e (typically from positions facing in the vicinity of the rear end), and are connected at distal ends thereof to the first and second

rotor arm portions

3a, 3 b. As shown in fig. 3, the first and

second connection portions

3c and 3d are typically provided to extend in a direction substantially orthogonal to the axial direction, but may be provided to be inclined forward and backward from a position orthogonal to the axial direction. In the embodiment shown in fig. 3, the width of the connection portion between the first and

second connection portions

3c and 3d and the rotor body 3e is wider than the other portions, the connection area is enlarged, and the stress at the connection portion is dispersed. In view of reducing the moment of inertia, the first and second

rotor arm portions

3a and 3b have a width smaller than the diameter of the substantially cylindrical body portion of the rotor body 3e, and the connecting portions between the first and second connecting

portions

3c and 3d and the first and second

rotor arm portions

3a and 3b have a thickness larger than the thickness of the other portions of the connecting portions, thereby increasing the strength of the connecting portions. In addition, the second rotor arm portion 3b (provided with the fishline guide portion) is most stressed particularly when taking up a fishline or when paying out a relief device, and the second connecting portion 3d connected to the second rotor arm portion 3b is made shorter in radial length than the first connecting portion 3c to increase the strength.

The first and second

rotor arm portions

3a and 3b are provided to extend forward from the rotor body 3e at a distance from the end portions of the first and second connecting

portions

3c and 3d at positions away from the rotor body 3e, respectively, and the string cup 5 is normally disposed between the two

arm portions

3a and 3 b. Typically, the first and second

rotor arm portions

3a and 3b extend forward substantially in parallel with the cylindrical rotor body 3e, but may extend forward without being parallel with the cylindrical rotor body 3e, for example, as long as the arrangement space of the bobbins is secured and the rotational balance of the entire rotor is secured.

The

arm portions

3a, 3b are formed at the other end with a hole 36 where the wire stopper 25 is supported freely swingably, and usually, on one of the

arm portions

3a, 3b, there are mounted a holding member 33 for holding the wire stopper at the fishing line take-up position and the fishing line pay-out position, and a jumping member 34 for automatically returning the wire stopper at the fishing line pay-out position to the fishing line take-up position in conjunction with the rotation of the swing arm, which are usually accommodated in a housing 35.

In the embodiment shown in fig. 3, the connection portions of the first and second

rotor arm portions

3a and 3b with the first and

second connection portions

3c and 3d are wider than the wire harness attachment side, so that the strength of the connection portions with the first and second connection portions 21 is increased. In other embodiments, the thickness of the first and second rotor arm portions may be set so that the connection portions with the first and second connection portions 21 are larger than the wire harness attachment side (including the case of using lamination) for the same purpose. Such a wide or thick structure can be used particularly for the second rotor arm portion 3 b.

On the other hand, in one embodiment of the present invention, a structure for reducing the weight and the moment of inertia of the rotor is provided. For example, as shown in fig. 3, the body portion 31, the mounting portion 32, and the first rotor arm portion 3a of the rotor body 3e are hollowed out so as to form openings, which are portions that are not normally subjected to large stress. From the same viewpoint, a hollow structure may be adopted.

In the embodiment shown in fig. 3, the rotor body 3e is integrally formed with first and second connecting

portions

3c and 3d, and the first and second

rotor arm portions

3a and 3b are fixed to the first and second connecting portions by fixing members 30 such as screws. In this configuration, the first and second

rotor arm portions

3a and 3b are formed as separate members, and can be formed into a basic shape such as a flat plate shape, which is advantageous in that the manufacturing process and raw material restrictions are small, and the manufacturing cost can be reduced.

In another embodiment, the rotor body 3e, the first and second connecting

portions

3c and 3d, and the first and second

rotor arm portions

3a and 3b may be formed as separate members, the first and second connecting

portions

3c and 3d may be connected to the rotor body 3e by fixing members (e.g., screws), and the first and second

rotor arm portions

3a and 3b may be connected to the first and second connecting

portions

3c and 3d by fixing members (e.g., screws), respectively, to form the rotor.

In this embodiment, the first and second connecting

portions

3c and 3d and the first and second

rotor arm portions

3a and 3b are formed as separate members and may be formed as flat plate-like members.

In the present invention, how to configure the rotor is not particularly limited, and the rotor may be configured by various plural members according to other embodiments. In addition, a method of connecting the members in the present invention is not particularly limited, and a known technique for connecting different kinds of materials may be used.

The fishing reel of the present invention is characterized in that the rotor body 3e and the first and second

rotor arm portions

3a, 3b are made of different materials. That is, in the above-described configuration of the rotor, when tension is generated in the fishing line in a state where the fishing line is engaged with the guide portion attached to the arm portion of the rotor, the arm portion is radially stressed inward, and the stress is applied to the entire rotor. In addition, from the viewpoint of the moment of inertia, it is understood that the weight of the first and second rotor arm portions, which are further from the rotation shaft, affects the moment of inertia more than the rotor main body located near the rotation shaft. To address this problem, the present invention uses multiple materials to construct the rotor.

More specifically, the first and second

rotor arm portions

3a, 3b are made of a material having a smaller specific gravity than that of the material constituting the rotor main body 3e, thereby effectively reducing the moment of inertia. In addition, the rotor body 3e, which has a small influence on the moment of inertia, is made of a metal material, so that the rigidity of the rotor body 3e is improved, and when the

arm portions

3a, 3b are radially forced in the inner side, the deformation of the rotor body 3e is reduced, and smooth operation is possible even in a state where the rotor is subjected to a large load.

The first and second

rotor arm portions

3a and 3b are preferably made of a material having a low specific gravity from the viewpoint of reducing the moment of inertia, but these

arm portions

3a and 3b, particularly the arm portion 3b having the fishline guide portion, are preferably made of a material having a high tensile strength, bending strength, or the like because of a large stress. Further, if the arm is swung too much, the fishing line may not be smoothly released when the weight-releasing device releases the line, and therefore, it is preferable to have a certain degree of rigidity.

From this viewpoint, examples of the material constituting the first rotor arm portion 3a include: polyamide resins (e.g., PA 66), engineering plastics such as ABS resins, polycarbonates, and polybutylene terephthalate, fiber-reinforced plastics such as glass fiber-reinforced plastics, carbon fiber-reinforced plastics, and resin fiber-reinforced plastics, and magnesium alloys, and carbon fiber-reinforced materials are preferred. Examples of the material constituting the second rotor arm portion 3b include: a fiber-reinforced material such as glass fiber-reinforced plastic or carbon fiber-reinforced material, or a magnesium alloy, and preferably a carbon fiber-reinforced material. In addition, the arm portion is formed of a material having a lower specific gravity than that of the rotor main body to effectively reduce the moment of inertia, and the rigidity of the rotor arm portion, particularly the second rotor arm portion 3a, may be reinforced by providing a reinforcing structure within a range not departing from the object.

As the fiber-reinforced material, it is preferable that the Young's modulus is 24tf/mm²Above, typically at 30tf/mm²To 60tf/mm²The laminate of fiber-reinforced materials of (3) may, for example, preferably include: mixing 24tf/mm²Above, typically 30tf/mm²To 60tf/mm²The carbon fiber prepreg of (a) is laminated, typically a laminate of 10 to 50 sheets.

On the other hand, the rotor body 3e may be made of any metal material, and may be made of various metal materials. However, in order to reduce the weight of the entire rotor and achieve higher operability, the rotor is preferably also made of a light metal material. Therefore, the metal material is preferably selected from the viewpoint of strength such as specific gravity, tensile strength, and bending strength, and rigidity. Specifically, examples of the material constituting the rotor body 3e include: aluminum alloys such as A360, magnesium alloys such as AZ91D, and the like. For a small rotor, a magnesium alloy such as AZ91D is preferable. When the rotor body 3e is made of a magnesium alloy, the

rotor arm portions

3a and 3b are made of the plastic.

In the embodiment shown in fig. 3, when the rotor body 3e, the first and

second connection portions

3c and 3d, and the first and second

rotor arm portions

3a and 3b are each formed as a separate member, the rotor body 3e, the first and

second connection portions

3c and 3d, and the first and second

rotor arm portions

3a and 3b may be formed of different materials, or the rotor body 3e and the first and second connection portions may be formed of the same material, and the first and second rotor arm portions may be formed of different materials, or the first and

second connection portions

3c and 3d and the first and second rotor arm portions may be formed of the same material, and the rotor body 3e may be formed of different materials. However, when the rotor body 3e and the first and second connecting

portions

3c and 3d are formed of different materials, the material of the first and second connecting portions is preferably a material having a lower specific gravity than the material of the rotor body 3e, from the viewpoint of effectively reducing the moment of inertia.

As described above, when the first and second connecting

portions

3c and 3d and the first and second

rotor arm portions

3a and 3b are formed as separate members, they can be formed as flat plate-like members, and therefore, there are few restrictions on the constituent materials, which is advantageous in terms of manufacturing process. From this point of view, in the present invention, the first and second connecting

portions

3c and 3d and the first and second

rotor arm portions

3a and 3b may be formed of a carbon fiber reinforced material.

In the present invention, the first connecting portion and the second connecting portion may be formed of different materials, and the first rotor arm portion and the second rotor arm portion may be formed of different materials. For example, in order to maintain the balance of the inertia moment, the arm portion to which the fishline guide is attached and the connecting portion to which the arm portion is connected may be made of a material having a lower specific gravity than the other arm portion and the connecting portion to which the other arm portion is connected. The first rotor arm portion and the second rotor arm portion may be formed of a material having a lower specific gravity than the material forming the first connecting portion and the second connecting portion, respectively.

In the case of a large rotor, a greater strength is required, and according to a preferred embodiment, the rotor body 3e (and the

connection parts

3c, 3d) is made of an aluminum alloy, preferably a360, and the

rotor arm parts

3a, 3b are made of a material having a Young's modulus of 24tf/mm²Above, typically at 30tf/mm²To 60tf/mm²The laminate or magnesium alloy obtained by laminating the carbon fiber prepreg of (3) is preferably AZ 91D.

Further, in the case of a small rotor, since the requirement for strength is generally lower than that of a large rotor, the structural emphasis can be placed on weight reduction, and according to a preferred embodiment, the rotor body 3e (and the

connection portions

3c and 3d) are made of a magnesium alloy, preferably AZ91D, and the

rotor arm portions

3a and 3b may be made of a material having a young's modulus of 24tf/mm²Above, typically 30tf/mm²To 60tf/mm²The carbon fiber prepreg of (1) or a carbon fiber-reinforced material comprising a polyamide resin and 30 to 50 wt% of carbon fibers. In this embodiment, the first rotor arm portion 3a may be made of a polyamide resin containing 30 to 50% by weightThe second rotor arm portion 3b may be made of a carbon fiber-reinforced material of carbon fiber (C), and the elastic modulus of expansion and contraction of which is 24tf/mm²Above, typically 30tf/mm²To 60tf/mm²The carbon fiber prepreg of (1) is laminated.

In the present invention, there is no particular limitation except for the material constituting the rotor, and various modifications and changes can be made in addition to the above matters.

For example, the thickness, shape, and structure of each member constituting the rotor may be appropriately changed in addition to the above-described structure in consideration of the strength such as bending strength and tensile strength, rigidity, and moment of inertia. For example, from the viewpoint of reducing the moment of inertia, the first and second rotor arm portions may be designed to have a shape of a curved surface having a radius of curvature almost coinciding with a virtual circle drawn from the cup axis to a virtual radius of the arm portion position.

In addition, various configurations may be adopted in order to maintain the balance of the moment of inertia of the entire rotor. For example, in the embodiment shown in fig. 3, when the holding member 33 and/or the jumping member 34 are provided, the distance between the second rotor arm portion 3b and the bobbin shaft 6 may be shorter than the distance between the other rotor arm portions 3a and the bobbin shaft 6. In addition, the

rotor arm portions

3a, 3b may be configured such that: when the rotor is viewed from the side where the arm portion of the rotor is provided, the wire stopper mounting position (36) of the arm portion is shifted in the vertical direction with respect to the bobbin axis.

The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments and various modifications are possible.

The present invention will be described more specifically below with reference to examples of the present invention. However, the examples do not set any limit to the present invention.

(example 1)

Carbon fiber-reinforced material (carbon fiber prepreg, 30 tf/mm) containing 70% by weight or more of carbon fibers is used²) The rotor arm portions were formed into 2 plate-like pieces by a lamination method. In addition, the rotor main body and the 2 connection portions were integrally manufactured by casting using a magnesium alloy (AZ 91D). By passingTitanium screws connect 2 rotor arms to the connecting portions, respectively, to make a rotor. The dimensions are shown in fig. 4.

(example 2)

The rotor was manufactured in the same manner as in example 1, except that 2 rotor arm portions were injection-molded using a carbon fiber reinforced material (PA66-CF30) in which 30 wt% of carbon fibers were contained in PA66 resin.

(example 3)

The rotor was manufactured as in example 1, except that the rotor main body and the 2 connection portions were integrally manufactured by casting using an aluminum alloy (a 360).

(example 4)

The rotor was manufactured in the same manner as in example 3, except that 2 rotor arm portions were injection-molded using a carbon fiber reinforced material (PA66-CF30) in which 30 wt% of carbon fibers were contained in PA66 resin.

Comparative example 1

The rotor was manufactured by integrally molding the rotor main body, 2 connecting portions, and 2 rotor arm portions by casting using a magnesium alloy (AZ 91D). The dimensions are the same as for the rotor of example 1.

Comparative example 2

The rotor body, 2 connecting portions, and 2 rotor arm portions were integrally formed of an aluminum alloy (a360) by casting molding, thereby producing a rotor. The dimensions are the same as for the rotor of example 1.

(size, weight, specific gravity, moment of inertia, deformation of various materials)

With respect to each rotor manufactured, the total weight, the moment of inertia at the center of gravity, and the deformation thereof were measured. The moment of inertia and the deformation at the center of gravity are measured as follows.

< moment of inertia at center of gravity >

The weight of the rotor is calculated from the size of the rotor and the specific gravity of the material constituting each part.

< deformation >

The evaluation was made based on the displacement of the rotor arm when a force of 5kgf was applied to the tip of the rotor arm of each rotor.

TABLE 1 inventive and comparative examples

As is clear from comparison of examples 1 and 2 and comparative example 1, when a magnesium alloy (AZ91D) is used for both the rotor body and the connecting portion, the inertia moment of the rotor during rotation can be effectively reduced by making the specific gravity of the constituent material of the rotor arm portion at a position farther from the rotation axis lower than the specific gravity of the constituent material of the rotor body at a position closer to the rotation axis, as in example 1 or 2. That is, the moment of inertia of comparative example 1 was 30220g mm when the magnesium alloy (AZ91D) was used for both the rotor body and the connection portion²And after the material of the rotor arm part is changed into Carbon CFRP or PA66+ CF 30% with lower specific gravity, the inertia moment of the rotor can be effectively reduced.

Similarly, when an aluminum alloy (a360) was used as the material of the rotor body and the connecting portion, the same conclusion can be obtained by comparing examples 3 and 4 with comparative example 2.
