Abstract

The invention discloses a lock sleeve. The lock sleeve comprises a lock sleeve body, a bearing sleeve cavity and a groove, the lock sleeve body is used for preventing inner rings of bearings from rotating on shafts; the bearing sleeve cavity is used for fixing bearings on the two shafts on the two sides of the lock sleeve body, the groove is used for fixing the two shafts and then fixing the two shafts through screws, the rockwell hardness of the groove is made to reach 37-44 by a heat treatment process and then phosphorization and paint coating treatment are carried out again so as to ensurethe structural strength during use;, wherein the surface roughness is obtained through a material removal method on the surface of the lock body, the bearing sleeve cavity and the groove, the wear resistance, the fatigue strength and the contact rigidity can be effectively improved, and the service life is prolonged. and is easy to machine and produce. The device has the advantages of being simplein structure, easy to machine and produce, capable of effectively reducing production cost and improving production efficiency.
