Description

Spinning wheel type fishing vessel for fishing

Filing and applying for separate cases

The application is a divisional application entitled "spinning wheel for fishing" with application number 201710423720.2, application date 2017, 6, 7.

Technical Field

The present invention relates to a spinning reel for fishing, in which a fishing line is wound around a wire cup that reciprocates in association with a rotation operation of a swing arm by a fishing line guide provided on a rotor that rotates in association with the rotation operation of the swing arm, and more particularly, to a spinning reel for fishing, in which the rotor is reduced in weight and the operability is improved.

Background

The spinning reel for fishing generally includes a swing arm attached to a reel body, a rotor having a line guide portion, and a line cup for winding a line, and is configured such that when the swing arm is rotated, the rotor rotates in conjunction with the rotation of the rotor, and the line cup reciprocates in an axial direction of the line cup, and the line is wound around the line cup via the guide portion. The rotor comprises a cylindrical rotor body, first and second connection parts extending radially outward from two opposite positions of a rear end part of the rotor body, a first rotor arm part and a second rotor arm part which are separated from the rotor body from the distal ends of the first and second connection parts and extend forward (on the side of a wire cup), wherein the first and second rotor arm parts are mounted in a state that a wire cup can freely rotate, a wire stop is mounted on the end parts of the first and second rotor arm parts in a freely swaying manner, in a wire collecting position, a wire is led into a wire guide part arranged on one side of the rotor arm parts by the wire stop, and the wire is wound on the wire cup moving forward and backward through the wire guide part.

When a fish is hooked, a large tension is generated in the line when the line is taken up by the swing arm or when the line is paid out by the sliding of the force-releasing device, and the arm portion of the rotor is subjected to a large force in the radial direction. The force can lead to the whole deformation of the rotor, and when the deformation is large, the rotor arm part can interfere with the wire cup to prevent the rotation of the rotor. Therefore, the arm portion to which a large force is applied is required to have not only a high bending strength and a high tensile strength but also a small deformation of the rotor body.

In addition, since the shape is relatively complicated as described above, there is a certain limit to the manufacturing method, the constituent materials, and the like in order to save costs, and conventional rotors are generally formed of a metal material and integrally molded by a casting method or the like.

On the other hand, in order to facilitate the reduction of the burden of holding the fishing tackle for a long period of time and the convenient handling of the fishing tackle, weight reduction of a fishing rod, a spinning reel for fishing, and the like is strongly demanded (patent document 1).

Accordingly, weight reduction of rotors constituting spinning reels for fishing has been studied, and light metals or their alloy materials, plastic materials, reinforced plastic materials, and the like have been used instead of metals having a large specific gravity (patent documents 1 and 2).

Among these lightweight materials, if the rotor is made of a light metal or an alloy thereof, a certain degree of weight reduction can be achieved, and since the tensile strength and bending strength are excellent and the rigidity is high, a rotor that does not undergo large deformation in its entirety even when the arm is subjected to a large force can be produced. Further, since the rotor can be integrally molded by a casting method or the like, there is an advantage in that a relatively complex rotor shape can be easily formed. Therefore, it is common practice to use a rotor integrally formed of a light metal such as a magnesium alloy or an aluminum alloy.

However, in the light metal rotor, there is a need for further improvement in terms of the reactivity to the rocker arm operation rotor at the start and end of the rotation operation.

On the other hand, if the rotor is made of a material having a smaller specific gravity, such as a plastic material or a reinforced plastic material, further weight reduction can be achieved, so that the degree of reaction to the rocker arm operation at the start and end of the rotation operation of the rotor can be improved. In particular, when the rotor is constructed using a fiber reinforced plastic in which a plastic is impregnated into carbon fibers or the like, the strength coefficient is extremely high, the tensile strength and bending strength are high as compared with those of the light metal, and a rotor having a high degree of reaction to the swing arm operation at the start and end of the rotation operation can be produced.

However, these materials have low rigidity, and if the rotor arm receives a large force, the rotor as a whole deforms, and even if the rotor arm interferes with the wire cup under the influence of the deformation, the rotation of the rotor is hindered. 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 an increase in moment of inertia.

In addition, although the tensile strength and bending strength of reinforced plastic materials, carbon fibers, and the like are extremely high, fibers are difficult to orient and mold, and when a rotor is manufactured from these materials, the rotor is often difficult to mold, and there is also a problem that the manufacturing 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-described problems, and an object of the present invention is to provide a spinning reel for fishing which is not only advantageous in weight saving of a fishing tackle, but also has a high degree of responsiveness to a swinging arm operation at the start and end of a swinging operation, and in which a rotor body is not deformed greatly even when an arm portion of the rotor is subjected to a large force, and which can perform a stable swinging operation.

[ means for solving the problems ]

In order to achieve the above object, the present inventors have paid attention to the fact that the moment of inertia is expressed substantially as a product of mass and diameter, and have proposed a rotor constructed of materials of different weights. That is, among the materials constituting the rotor, the rotor arm portion or the rotor arm portion and the connecting portion which are farther from the rotation shaft are constituted by a material having a lower specific gravity than the material constituting the rotor main body which is closer to the rotation shaft, so that the moment of inertia can be effectively reduced, and the operability at the start and end of the rotation operation can be improved. In addition, by using a material with high rigidity to construct the rotor body, 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 has been developed based on this idea.

That is, the present invention provides a spinning wheel for fishing, comprising: the fishing reel comprises a fishing reel body, a rocker arm rotatably mounted on the fishing reel body, a wire cup which is in linkage with the rotation of the rocker arm and reciprocates back and forth along a wire cup shaft, and a rotor which is in linkage with the rotation of the rocker arm and rotates around the wire cup shaft; the rotor is composed of a rotor main body with a substantially cylindrical shape, a first connecting part and a second connecting part which extend outwards along radial direction from 2 opposite positions of the rotor main body, a first rotor arm part and a second rotor arm part which are separated from the rotor main body from radial distal ends of the first connecting part and the second connecting part and extend forwards (on a wire cup side) respectively, and a fishing line can be wound on the wire cup through a fishing line guide part arranged on one side of the rotor arm part; wherein the rotor body is made of a metal material, and the first and second rotor arm portions are made 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 a magnesium alloy such as AZ91D, and the material constituting the rotor arm is a fiber-reinforced plastic such as glass fiber-reinforced plastic, carbon fiber-reinforced plastic or resin fiber-reinforced plastic, or a magnesium alloy.

In a preferred embodiment of the present invention, the first and second rotor arm portions are provided as: the distance from the second rotor arm to the cup axis (shortest distance when the second rotor arm is not parallel to the cup axis) is closer than the distance from the first rotor arm to the cup axis (shortest distance when the second rotor arm is not parallel to the cup axis).

[ Effect of the invention ]

According to the spinning wheel for fishing of the present invention, since the constituent material of the rotor arm portion at a position farther from the rotation axis has a lower specific gravity than the constituent material of the rotor body at a position closer to the rotation axis, the moment of inertia of the rotor at the time of rotation is effectively reduced, and the rotor reacts sensitively to the operation of the swing arm at the time of rotation start and at the time of rotation end, and the operation sensitivity is improved. In addition, the sensitivity of the biting and catching is improved in response to the tension change of the fish line.

In addition, the present invention can be configured only with the rotor arm portion using a reinforcing material, particularly a laminate of carbon fiber reinforcing materials, and the like, and it is not necessary to form a member of a complicated shape using these materials. Therefore, the rotor is manufactured simply and at a lower cost than when the rotor is integrally formed from these materials.

Detailed Description

Embodiments of a spinning reel for fishing according to the present invention will be described below with reference to the accompanying drawings. In addition, in all the context of the present application, axial refers to the direction along the line cup axis, rear refers to the side of the target member that is closer to the reel body, and front refers to the side of the target member that is closer to the line cup.

Fig. 1 schematically shows the whole appearance of a spinning wheel for fishing according to an exemplary embodiment of the present invention, and fig. 2 schematically shows the basic internal structure thereof. Fig. 3 shows an outline of a rotor according to an embodiment of the present invention, which is a top view (a), a front view (B) (a view seen from an arrow a side of fig. 3 (a)), and a side view (a view seen from an arrow B of fig. 3 (a)), respectively.

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

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

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

As shown in fig. 2, the transmission mechanism for transmitting the rotation operation of the swing arm 2 to the wire cup 5 generally includes: a swing gear 16 engaged with a reduction gear 15 integrally mounted on the rocker shaft 2a, and a slider 17, the slider 17 having a swing groove 17a engaged with a projection 16a provided therearound. The slider 17 is fixed to the cup shaft 6, and the rotation of the swing gear 16 is converted into the reciprocating motion of the cup shaft 6 by the engagement of the protrusion 16a provided around the slider 17 and the swing groove 17a, so that the cup 5 fixed to the cup shaft 6 is interlocked and reciprocates.

The wire cup 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 wire cup 5 reciprocates back and forth along the wire cup shaft 6 while the rotor 3 rotates by rotating the operating rocker arm 2, and the fishing line 4 is wound around the winding groove 5a of the wire cup 5 through the fishing line guide 24 provided on the rotor 3.

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

second connection portions

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

rotor arm portions

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

second connection portions

3c and 3d remote from the rotor body 3e, respectively, 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 31 and a plate-like mounting portion 32 extending in a direction substantially orthogonal to the axial direction and fixed to the body 31, and an opening 32a is provided in the center of the mounting portion 32. The pinion gear 12 is inserted into the opening 32a, and is fixed to the rotor 3 by a fixing member 30 such as a nut. The pinion gear 12 has a generally elongated cylindrical shape, and has a cup shaft 6 penetrating therethrough, and a bearing is disposed on an inner peripheral surface of the pinion gear 12 so as to be spaced apart from the cup shaft 6 by a predetermined distance. In the embodiment shown in fig. 3, the bottom 31a of the trunk 31 is thicker than the other parts (31, 32) of the trunk 31, and 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 easy to concentrate is concentrated.

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

portions

3c, 3d are generally provided so as to protrude radially outward from a position opposed to the outer peripheral surface of the substantially cylindrical trunk portion 31 of the rotor main body 3e (typically, from a position opposed near the rear end), and are connected at distal ends thereof to the first and second

rotor arm portions

3a, 3b. 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 back and forth from a position orthogonal to the axial direction. Since the portion connected to the rotor body 3e and the first and second

rotor arm portions

3a and 3b is a portion where stress is easily concentrated, it is preferable to increase the strength, and in the embodiment shown in fig. 3, the width of the portion connected to the rotor body 3e at the first and

second connection portions

3c and 3d is wider than that at other portions, so that the connection area is enlarged and the stress at the connection portion is dispersed. In addition, from the viewpoint of reducing the moment of inertia, the widths of the first and second

rotor arm portions

3a, 3b are smaller than the diameter of the substantially cylindrical trunk portion of the rotor body 3e, and the strength of the connection portion is increased by making the thickness of the connection portion between the first and

second connection portions

3c, 3d and the first and second

rotor arm portions

3a, 3b larger than the other portions of the connection portion. In addition, the stress applied to the second rotor arm portion 3b (provided with the line guide portion) is maximized particularly when the line is taken up or the line is paid out by the force release device, and the radial length of the second connection portion 3d connected to the second rotor arm portion 3b is made shorter than that of the first connection portion 3c to increase the strength.

The first and second

rotor arm portions

3a, 3b are provided so as to be spaced apart from the rotor body 3e from the end portions of the first and

second connection portions

3c, 3d at positions distant from the rotor body 3e, respectively, and extend forward, respectively, and typically, a wire cup 5 is disposed between the two

arm portions

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

rotor arm portions

3a and 3b extend forward substantially parallel to the cylindrical rotor body 3e, but may not extend forward, for example, parallel to the cylindrical rotor body 3e, as long as the arrangement space of the wire cup is ensured and the rotation balance of the rotor as a whole is ensured.

These

arm portions

3a, 3b are formed with holes 36 at the other end where the wire stopper 25 is swingably supported, and typically, on one of these

arm portions

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

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

rotor arm portions

3a, 3b with the first and

second connection portions

3c, 3d are wider than the wire stopper mounting side, so that the strength of the connection portions with the first and second connection portions 21 is increased. In other embodiments, for the same purpose, the thicknesses of the first and second rotor arm portions may be set to a shape in which the connection portions with the first and second connection portions 21 are larger than the wire guide mounting side (including the case of using lamination). In particular, in the second rotor arm portion 3b, such a wide or thick structure may be used.

On the other hand, in one embodiment of the present invention, a structure for reducing weight of the rotor and reducing the moment of inertia is also provided. For example, as shown in fig. 3, the trunk 31, the attachment 32, and the first rotor arm 3a of the rotor body 3e are hollowed out to form openings in portions that are not subjected to a large stress. In addition, from the same point of view, a hollow structure may be employed.

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

second connection portions

3c and 3d, and the first and second

rotor arm portions

3a and 3b are fixed to the first and second connection portions by fixing members 30 such as screws, respectively. In this structure, 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, which has advantages of small restrictions on manufacturing processes and raw materials, and reduction in manufacturing costs.

In other embodiments, 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 as separate members, the first and

second connection 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 connection portions

3c and 3d by fixing members (e.g., screws).

In this embodiment, the first and

second connection portions

3c, 3d and the first and second

rotor arm portions

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

In the present invention, how to construct the rotor is not particularly limited, and according to other embodiments, the rotor may be constructed by various multiple components. In addition, the method of connecting the members in the present invention is not particularly limited, and known techniques for connecting different kinds of materials can 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 rotor structure described above, when the line is engaged with the guide portion attached to the arm portion of the rotor, the arm portion is forced in the inner radial direction after tension is generated in the line, and the stress propagates to the entire rotor. In addition, from the point of view of moment of inertia, it should be appreciated that the weight of the first and second rotor arms further from the axis of rotation affects the moment of inertia more than the rotor body located near the axis of rotation. In response to this problem, the present invention uses a variety of 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 the material constituting the rotor body 3e, thereby effectively reducing the moment of inertia. In addition, the rotor body 3e having less 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 forced in the inner radial direction, the deformation of the rotor body 3e is reduced, and the operation can be smoothly performed even in a state where the rotor is subjected to a large load.

From the viewpoint of reducing the moment of inertia, a material having a small specific gravity is preferable as a material constituting the first and second

rotor arm portions

3a and 3b, but a material having a high tensile strength, bending strength, and the like is preferable because the

arm portions

3a and 3b, particularly the arm portion 3b having the line guide portion, are highly stressed. Further, if the arm is swung too much, the line may not be smoothly discharged when the force release device is paying out, and therefore, it is preferable to have a certain degree of rigidity.

From this point of view, as a material constituting the first rotor arm portion 3a, there may be mentioned: an engineering plastic such as polyamide resin (for example, PA 66), ABS resin, polycarbonate, and polybutylene terephthalate, a fiber reinforced material such as glass fiber reinforced plastic, carbon fiber reinforced material, resin fiber reinforced plastic, or magnesium alloy, and a carbon fiber reinforced material is preferable. As a material constituting the second rotor arm portion 3b, there may be mentioned: the fiber reinforced plastic, carbon fiber reinforced material, or magnesium alloy is preferably a carbon fiber reinforced material. The arm portion is formed of a material having a lower specific gravity than that of the rotor body, so that the moment of inertia can be effectively reduced, and the rigidity of the rotor arm portion, particularly the second rotor arm portion 3a, can be reinforced by providing a reinforcing structure within a range not departing from the object.

As the fiber-reinforced material, a Young's modulus of 24tf/mm is preferable ² Above, typically at 30tf/mm ² To 60tf/mm ² For example, preferable examples of the laminate of the fiber-reinforced material of (a) include: will be 24tf/mm ² The above is typically 30tf/mm ² To 60tf/mm ² The carbon fiber prepreg of (a) is typically a laminate of 10 to 50 sheets.

On the other hand, the rotor body 3e may be made of various metal materials as long as it is made of a metal material. However, in order to reduce the weight of the entire rotor to achieve higher operability, the rotor is also preferably made of a light metal material. Therefore, the metal material is preferably selected from the viewpoints of strength such as specific gravity, tensile strength, and bending strength, and rigidity. Specifically, as a material constituting the rotor body 3e, there may be mentioned: aluminum alloys such as a360, magnesium alloys such as AZ91D, and the like. For small rotors, magnesium alloys such as AZ91D are preferred. When the rotor body 3e is made of magnesium alloy, the

rotor arm portions

3a and 3b are made of the plastic.

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

second connection portions

3c, 3d, and the first and second

rotor arm portions

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

second connection portions

3c, 3d, and the first and second

rotor arm portions

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

second connection portions

3c, 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 connection portions

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

As described above, when the first and

second connection portions

3c and 3d and the first and second

rotor arm portions

3a and 3b are manufactured as separate members, they can be manufactured as flat plate-like members, and therefore, these constituent materials have less restrictions, and are advantageous in terms of manufacturing process. From this point of view, in the present invention, the first and

second connection portions

3c, 3d and the first and second

rotor arm portions

3a, 3b may be made 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 balance of the moment of inertia, the arm portion to which the fishing line guide portion 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 constituent materials of 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 made of a material having a lower specific gravity than the material constituting 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 connecting

portions

3c, 3 d) is made of an aluminum alloy, preferably A360, and the

rotor arm portions

3a, 3b are made of a material having a Young's modulus of 24tf/mm ² Above, typically at 30tf/mm ² To 60tf/mm ² Laminate or magnesium alloy obtained by laminating carbon fiber prepregs of (a)Preferably AZ 91D.

In addition, in a small rotor, since the strength is generally lower than in a large rotor, the weight of the structure can be reduced, and according to a preferred embodiment, the rotor body 3e (and the connecting portions 3c and 3D) is made of magnesium alloy, preferably AZ91D, and the

rotor arm portions

3a and 3b can be made of a material having a young's modulus of 24tf/mm ² The above is typically 30tf/mm ² To 60tf/mm ² A laminate of carbon fiber prepregs laminated or a carbon fiber reinforced material in which 30 to 50 wt% of carbon fibers are contained in a polyamide resin. In this embodiment, the first rotor arm 3a may be preferably made of a carbon fiber reinforced material in which 30 to 50 wt% of carbon fibers are contained in a polyamide resin, and the second rotor arm 3b may be preferably made of a material having a tensile elastic modulus of 24tf/mm ² The above is typically 30tf/mm ² To 60tf/mm ² Is formed by laminating carbon fiber prepregs.

In the present invention, there is no particular limitation except for the materials constituting the rotor, and various modifications and alterations 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 view of 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 curved shape having a radius of curvature almost corresponding to a virtual circle drawn from the wire cup axis to the virtual radius of the arm portion position.

In addition, various structures may be employed in order to maintain the balance of the moment of inertia of the rotor as a whole. 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 cup shaft 6 may be shorter than the distance between the other rotor arm portion 3a and the cup shaft 6. In addition, the

rotor arm portions

3a, 3b may be configured to: when the rotor is viewed from the side where the rotor arm is provided, the wire stopper attachment position (36) of the arm is shifted in the up-down direction with respect to the wire cup shaft.

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

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

Using a carbon fiber-reinforced material containing 70 wt% or more of carbon fibers (carbon fiber prepreg, 30 tf/mm) ² ) 2 plate-like rotor arm portions were manufactured by a lamination method. In addition, the rotor body and 2 connection portions were integrally manufactured by casting using a magnesium alloy (AZ 91D). The 2 rotor arm portions were respectively connected to the connection portions by titanium screws to make the 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 manufactured by injection molding using a carbon fiber reinforced material (PA 66-CF 30) containing 30 wt% of carbon fibers in PA66 resin.

Example 3

The manufacture of the rotor was the same as that of example 1, except that the rotor body and 2 connection portions were integrally manufactured by casting using the 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 manufactured by injection molding using a carbon fiber reinforced material (PA 66-CF 30) containing 30 wt% of carbon fibers in PA66 resin.

Comparative example 1

The rotor body, 2 connection portions, and 2 rotor arm portions were integrally molded by casting molding with a magnesium alloy (AZ 91D), to thereby manufacture a rotor. The dimensions are the same as for the rotor of example 1.

Comparative example 2

The rotor body, 2 connection portions, and 2 rotor arm portions were integrally molded by casting molding from an aluminum alloy (a 360), thereby manufacturing a rotor. The dimensions are the same as for the rotor of example 1.

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

For each rotor produced, the total weight, moment of inertia at the center of gravity and deformation were measured. The moment of inertia and deformation at the center of gravity are measured as follows.

< moment of inertia at center of gravity >

Calculated from the size of the rotor and the specific gravity of the material constituting each part.

< deformation >

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

< results >

Table 1 inventive examples and comparative examples vs

As is clear from comparison of example 1, example 2 and comparative example 1, when the magnesium alloy (AZ 91D) is used for both the rotor body and the connecting portion, as in example 1 or example 2, the moment of inertia of the rotor during rotation can be effectively reduced by making 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. That is, in the case where the magnesium alloy (AZ 91D) was used for both the rotor body and the connection portion, the moment of inertia of comparative example 1 was 30220g·mm ² The inertia moment of the rotor can be effectively reduced after the material of the rotor arm is changed into Carbon CFRP or PA66+CF30% with lower specific gravity.

Similarly, when the aluminum alloy (a 360) was used as the material for the rotor body and the connecting portion, the same conclusion was obtained by comparing example 3, example 4 and comparative example 2.
