Abstract
The invention relates to a motor belt pulley, which comprises a belt pulley body, wherein a dustproof cover is fixedly sleeved at one end of the belt pulley body which is connected with a motor shaft. The assembling method of the motor belt pulley comprises the following step of: directly injecting and molding the dustproof cover at one end of the belt pulley body which is connected with the motor shaft with an injection molding process by taking the belt pulley body as an insert. The motor belt pulley with the dustproof cover and the assembling method thereof, provided by the invention, have the advantages of low cost, simple process and convenience for assembling.
Description
Technical field
The present invention relates to a kind of motor pulley and assembly method thereof with nonmetal dust-proof cover.
Background technique
The prior motor belt pulley is a pure metal spare, and its end diameter that is used for being connected with motor shaft is less, can not cover the gap between motor shaft and the electric motor end cap, causes dust, foreign material often to fall in the motor from this gap, influences the proper functioning of motor.If the diameter of an end that can motor pulley is used for being connected with motor shaft increases until covering the gap fully; So just can prevent effectively that dust, foreign material from falling in the motor; The motor pulley of this kind structure is brand-new, does not also have this belt pulley that has dustproof construction to occur at home and abroad at present.
Summary of the invention
The objective of the invention is to overcome the defective that existing technology exists, a kind of motor pulley and assembly method thereof that has dust-proof cover is provided, and its cost is low, technology is simple, easy to assembly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of motor pulley, comprise pulley body, and an end fixed cover that is used on the described pulley body being connected with motor shaft is connected to dust-proof cover.
Further, in order to reduce cost, described dust-proof cover is plastic cement or rubber parts.
Further, in order to increase the area of contact of pulley body and dust-proof cover, prevent dust-proof cover cracking or axle, move radially, the joint with dust-proof cover on the said pulley body is provided with the annular knurl structure.
Further, described dust-proof cover is cylinder or cone, and its central shaft overlaps with the central shaft of pulley body.
A kind of method of assembling above-mentioned motor pulley, its step is following: with pulley body as mold insert, an end injection moulding dust-proof cover that directly on pulley body, is used for being connected through Shooting Technique with motor shaft.
Beneficial effect of the present invention: the invention solves the defective that exists in the background technique, the diameter of the end that motor pulley is used for being connected with motor shaft increases, and makes it can cover the gap between motor shaft and the electric motor end cap fully; Played sealing, dust-tight effect, and, motor pulley one end diameter has been increased realize through integral type injection moulding non-metal part in order to reduce cost; The present invention uses plastics or rubber parts; Greatly reduce cost of production, and technology is simple, easy to assembly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is the structural representation of motor pulley;
Fig. 2 is the A-A sectional view of motor pulley among Fig. 1;
Fig. 3 is the perspective view of motor pulley.
Wherein: 1, pulley body; 11, annular knurl structure; 2, dust-proof cover; 22, groove.
Embodiment
Like Fig. 1, Fig. 2, a kind of motor pulley shown in Figure 3; Comprise pulley body 1, it is a metallic material, and an end fixed cover that is used for being connected with motor shaft on the described pulley body 1 is connected to dust-proof cover 2; It is shaped as cylinder or cone; And its central shaft overlaps with the central shaft of pulley body 1, so works as the present invention and is not limited to a fixing dust-proof cover shape, can design arbitrarily according to demand.For reducing cost; This dust-proof cover 2 is nonmetallic material such as plastic cement or rubber, and has some grooves 21 on this dust-proof cover 2, can save raw material so more; For attractive in appearance; Said groove 21 is opened the end face at an end that is used for being connected with motor shaft of dust-proof cover 2, and this end face is against on the electric motor end cap and covers the gap between electric motor end cap and the motor shaft fully, plays sealing, dustproof effect.
In order to increase the area of contact of pulley body 1 and dust-proof cover 2, prevent dust-proof cover 2 crackings or axle, move radially, the joint with dust-proof cover 2 on the said pulley body 1 is provided with annular knurl structure 11, and this structure plays the effect of centering in injection moulding.
A kind of method of assembling above-mentioned motor pulley, its step is following: with pulley body 1 as mold insert, an end injection moulding dust-proof cover 2 that directly on pulley body 1, is used for being connected through Shooting Technique with motor shaft.
Claims (6)
