Embodiment Construction
[0021] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] The design concept of the technical solution of the present invention is: one end of the bearing nut 3 is pressed against the inner ring 5 of the bearing, a number of grooves are opened on the other end of the bearing nut 3 and the journal 4, and a lock plate 1 with multiple teeth inside and outside is designed, and multiple teeth are assembled in the groove. Tooth lock piece 1, the outer teeth 6 and inner teeth 7 of the lock piece 1 prevent the bearing nut 3 from loosening, and the retaining ring 2 is used to fix the lock piece to prevent the lock piece 1 from withdrawing axially. The locking piece is formed to prevent the nut from loosening, and the retaining ring axially fixes the structure of the locking piece. During the working process, the multi-tooth structure of the locking piece constrains each other, and will not vibrate un...
