The purpose of this utility model is mainly achieved by following proposal: a kind of damper pulley assembly, comprise belt pulley and timing sprocket, described belt pulley is provided with several card convexs on the end face of timing sprocket, timing sprocket is provided with the draw-in groove matched with card convex on the end face of belt pulley, and belt pulley is connected with timing sprocket bolt.The section laminating of belt pulley and timing sprocket, on the end face of timing sprocket, several card convexs are provided with at belt pulley, timing sprocket is provided with the draw-in groove matched with card convex on the end face of belt pulley, card convex on belt pulley is inserted in the draw-in groove on timing sprocket, draw-in groove on timing sprocket can be spacing to the card convex on belt pulley, then timing sprocket and belt pulley are fixed by bolt.Because card convex and draw-in groove are all arranged on end face, when timing sprocket and belt pulley rotate, the cooperation of card convex and draw-in groove can transmitting torque effectively, and damper pulley assembly wheel hub can be avoided to break, and ensures the normal operation of motor.
As preferably, described card convex is kidney ellipsoid.Card convex is kidney ellipsoid, draw-in groove in the kidney ellipsoid that coordinates with card convex, when card convex rotates to different direction, kidney ellipsoid face directly and cambered surface all can ensure the transmission of the spacing and moment of torsion between draw-in groove and card convex.
Described card convex also can be rectangular.Card convex is rectangular, and draw-in groove is in the rectangle coordinated with card convex, and when card convex rotates to different direction, four vertical surfaces of kidney ellipsoid all can ensure the transmission of the spacing and moment of torsion between draw-in groove and card convex.
Described card convex also can be provided with several latches around card convex in outside, and latch bends towards the opposite direction of belt pulley sense of rotation; The outside of draw-in groove is provided with the restraining groove matched with latch around draw-in groove.Outside card convex, latch is set around card convex, and latch is warp architecture, bending direction is towards the opposite direction of belt pulley sense of rotation, not only increase the limit effect of draw-in groove and card convex cooperation, and utilize restraining groove to latch transmitting torque, the stability that enhancing timing sprocket is connected with belt pulley and intensity.
As preferably, described card convex is evenly arranged around the axis of belt pulley.Card convex is evenly arranged around the axis of belt pulley, and ensure belt pulley uniform force, the moment of torsion of transmission is even.
Therefore, damper pulley assembly of the present utility model possesses following advantage: 1, the section laminating of belt pulley and timing sprocket, on the end face of timing sprocket, several card convexs are provided with at belt pulley, timing sprocket is provided with the draw-in groove matched with card convex on the end face of belt pulley, card convex on belt pulley is inserted in the draw-in groove on timing sprocket, draw-in groove on timing sprocket can be spacing to the card convex on belt pulley, by bolt, timing sprocket and belt pulley are fixed again, because card convex and draw-in groove are all arranged on end face, when timing sprocket and belt pulley rotate, the cooperation of card convex and draw-in groove can transmitting torque effectively, and damper pulley assembly wheel hub can be avoided to break, ensure the normal operation of motor, 2, outside card convex, latch is set around card convex, and latch is warp architecture, bending direction is towards the opposite direction of belt pulley sense of rotation, not only increase the limit effect of draw-in groove and card convex cooperation, and utilize restraining groove to latch transmitting torque, the stability that enhancing timing sprocket is connected with belt pulley and intensity.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, a kind of damper pulley assembly, comprises belt pulley 1 and timing sprocket 2, the end face laminating of belt pulley and timing sprocket.Belt pulley is processed with six card convexs 3 on the end face of timing sprocket, and card convex is evenly arranged around the axis of belt pulley.Timing sprocket has the draw-in groove 4 matched with card convex on the end face of belt pulley, and belt pulley is connected by bolt 7 with timing sprocket.As shown in Figure 2, card convex is the protruding structure of kidney ellipsoid.As shown in Figure 3, the groove structure of draw-in groove 4 in kidney ellipsoid on timing sprocket.
The section laminating of belt pulley and timing sprocket, on the end face of timing sprocket, several card convexs are provided with at belt pulley, timing sprocket is provided with the draw-in groove matched with card convex on the end face of belt pulley, card convex on belt pulley is inserted in the draw-in groove on timing sprocket, draw-in groove on timing sprocket can be spacing to the card convex on belt pulley, then timing sprocket and belt pulley are fixed by bolt.Because card convex and draw-in groove are all arranged on end face, when timing sprocket and belt pulley rotate, the cooperation of card convex and draw-in groove can transmitting torque effectively, and damper pulley assembly wheel hub can be avoided to break, and ensures the normal operation of motor.Card convex is kidney ellipsoid, draw-in groove in the kidney ellipsoid that coordinates with card convex, when card convex rotates to different direction, kidney ellipsoid face directly and cambered surface all can ensure the transmission of the spacing and moment of torsion between draw-in groove and card convex.Card convex is evenly arranged around the axis of belt pulley, and ensure belt pulley uniform force, the moment of torsion of transmission is even.
Embodiment 2: the present embodiment is substantially identical with the structure of embodiment 1, and difference is, as shown in Figure 4, and the protruding structure that the card convex 3 on belt pulley 1 is rectangular, the groove structure that the draw-in groove on timing sprocket is rectangular.Card convex is rectangular, and draw-in groove is in the rectangle coordinated with card convex, and when card convex rotates to different direction, four vertical surfaces of kidney ellipsoid all can ensure the transmission of the spacing and moment of torsion between draw-in groove and card convex.
Embodiment 3: the present embodiment is substantially identical with the structure of embodiment 1 or 2, and difference is, as shown in Figure 5,6, is processed with latch 5 outside card convex 3 around card convex, and latch bends towards the opposite direction of belt pulley sense of rotation, and latch is ratchet-type structure.As shown in Figure 7, the outside of the draw-in groove of timing sprocket has the restraining groove 6 matched with latch around draw-in groove.Outside card convex, latch is set around card convex, and latch is warp architecture, bending direction is towards the opposite direction of belt pulley sense of rotation, not only increase the limit effect of draw-in groove and card convex cooperation, and utilize restraining groove to latch transmitting torque, the stability that enhancing timing sprocket is connected with belt pulley and intensity.
