Problems solved by technology

[0002] Usually, the automobile engine adopts the pulley to realize the transmission with the automobile engine through the transmission belt. In order to reduce the impact, vibration and noise of the pulley during the acceleration and deceleration process, a one-way overrunning pulley is used. The existing one-way overrunning pulley includes a pulley, a mandrel, a clutch and a support Bearings, the pulley is set on the outer side of the mandrel and coaxially arranged, the support bearings are two, respectively supported at the left and right ends between the pulley and the mandrel, the needle clutch is located between the two support bearings, and It is used for torque transmission between the pulley and the mandrel; the existing clutch structure has an inner ring and an outer ring, and the structure is relatively complicated. Therefore, more parts will affect the transmission accuracy of the pulley, and there will be more factors affecting the transmission accuracy of the pulley, which will affect the use of the pulley

Embodiment 1

[0032] Such as Figure 1-Figure 5 As shown, a generator one-way pulley of the present invention includes a pulley 1 for power input, a shaft sleeve 2 for power output and matched with the mandrel, and a power pulley between the pulley 1 and the shaft sleeve 2. The transmission one-way clutch and the end cover 10 on the side opposite to the output end of the mandrel are arranged on the pulley 1. The one-way clutch is arranged in the middle of the shaft sleeve 2, and the two ends of the one-way clutch pass through the bearings. 3 Sealing, the preferred bearing 3 adopts deep groove ball bearings.

[0033] Such as Figure 3-Figure 5 As shown, the one-way clutch includes a clutch outer ring 4, a roller 5, a cage 6 and a leaf spring 7, the inner hole of the clutch outer ring 4 is provided with a wedge-shaped groove 41, and the cage 6 is fixed on a wedge-shaped In the groove 41, the leaf spring 7 is fixed on the cage 6, and the cage 6 is provided with a plurality of windows 63 alon...

Embodiment 2

[0042] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the cooperation between the bearing outer ring 32 and the inner hole of the pulley 1 is different, and the bearing outer ring 32 on the side close to the end cover 10 and the inner hole of the pulley 1 A clearance fit is adopted, and an interference fit is adopted between the bearing outer ring 32 at the other end and the inner hole of the pulley 1, which is the same as that in Embodiment 1. Specifically, a sealing ring 8 and a sealing groove 9 arranged on the inner hole of the pulley 1 are also included. The sealing ring 8 is placed in the sealing groove 9 and is in close contact with the bearing outer ring 32 . The matching mode of both sides can also be exchanged, the side close to the end cover 10 is interference fit, and the other side is clearance fit.

Embodiment 3

[0044] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the cooperation between the bearing outer ring 32 and the inner hole of the pulley 1 is different. Specifically, both sides of the bearing outer ring 32 and the inner hole of the pulley 1 adopt The clearance fit also includes a sealing ring 8 and a sealing groove 9 provided on the inner hole of the pulley 1 , the sealing ring 8 is placed in the sealing groove 9 and closely fits with the bearing outer ring 32 .

[0045] The bearing 3 in the above three embodiments adopts a ball bearing, and the outer ring 32 of the bearing in the first embodiment is in interference fit with the inner hole of the pulley 1. The inner hole of the pulley 1 in this structure is smooth and does not require processing, and the structure is relatively simple. It is easy to process; however, because the interference fit is equivalent to a rigid connection, the clearance of the assembly is affected by the p...

Abstract

The invention provides a generator one-way belt wheel. The generator one-way belt wheel comprises a belt wheel body, a shaft sleeve and a one-way clutch, the one-way clutch is arranged in the middle of the shaft sleeve, and the two ends of the one-way clutch are sealed through bearings; the one-way clutch comprises a clutch outer ring, balls, a retainer and steel sheet springs; a wedge-shaped groove is formed in the inner hole of the clutch outer ring, the retainer is fixed in the wedge-shaped groove, the steel sheet springs are fixed on the retainer, a plurality of windows are formed in the retainer along the circumferential direction of the retainer, and balls used for torque transmission is arranged in each window; the steel sheet springs presses the balls tightly on the inner wall of the wedge-shaped groove and the outer wall of the shaft sleeve, and when the outer ring of the clutch rotates clockwise, the clutch outer ring and the shaft sleeve are tightly wedged together through the balls; when the clutch outer ring rotates anticlockwise, the clutch outer ring and the shaft sleeve are separated. The generator one-way belt wheel has the advantages that the structure is simple,the number of parts is small, the work is stable and reliable, and the machining precision is easy to guarantee.
