Document Type and Number:
WIPO Patent Application WO/2024/051065
Kind Code:
A1
Abstract:
The present invention belongs to the field of bearings, and particularly relates to a bearing slipping prevention structure, a bearing and a wave spring. The bearing slipping prevention structure comprises a bearing seat, a bearing and a rotating shaft which are successively connected, and further comprises a stop cushion block; the stop cushion block is provided with stop blocks or stop recesses on both two sides along the axis of the bearing; one side of the stop cushion block is attached to one side of the bearing; the side of the bearing matched with the stop cushion block is provided with a matching recess I or matching block I which is in embedded fit with a stop block or stop recess; a bore shoulder of the bearing seat or a shaft shoulder of the rotating shaft is provided with a matching recess II or matching block II matched with the other stop block or stop recess. The present invention achieves circumferential locking between the bearing and the bearing seat or between the bearing and the rotating shaft, effectively preventing slipping of bearings; in addition, the function of automatic alignment and installation is achieved during the installation process, improving the reliability and NVH performance and prolonging the service life of products while reducing the number of parts, reducing the product manufacturing costs and improving product manufacturing efficiency.
