Abstract
The utility model relates to a belt pulley of a motor, which comprises a belt pulley body, wherein one end on the belt pulley body, which is used for being connected with a motor shaft, is fixedly in sleeve joint with a dustproof cover. The utility model provides a belt pulley of a motor, which is provided with a dustproof cover, and an assembly method of the belt pulley of the motor. Moreover, the utility model has low cost and simple process and is convenient to assemble.
Description
Technical field
The utility model relates to a kind of motor pulley 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 motor pulley can be used for the diameter of the end that is 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.
The model utility content
The purpose of this utility model is to overcome the defective that prior art exists, and provide a kind of motor pulley that has dust-proof cover, and its cost is low, and technology is simple, easy to assembly.
The technological scheme that its technical problem that solves the utility model adopts 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 described 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.
The beneficial effects of the utility model: the utility model has solved 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, make it can cover gap between motor shaft and the electric motor end cap fully, sealing, dust-tight effect have been played, and in order to reduce cost, motor pulley one end diameter is increased to be realized by integral type injection moulding non-metal part, the utility model uses plastics or rubber parts, greatly reduce cost of production, and technology is simple, and is easy to assembly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
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
As Fig. 1, Fig. 2, a kind of motor pulley shown in Figure 3, comprise pulley body 1, it is a metallic material, 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 utility model 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 have some grooves 21 on this dust-proof cover 2, can save raw material more like this, for attractive in appearance, described 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 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 described 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 as follows: 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 by Shooting Technique with motor shaft.
