Abstract

The invention discloses a bearing positioning structure. The bearing positioning structure is composed of a lock nut, an O-shaped ring and an end cover. During installation, a gap is adjusted by screwing a bearing into the lock nut or unscrewing the bearing from the lock nut, a thread is sealed through the O-shaped ring, and thus oil leakage is prevented. The lock nut for positioning the bearing has a self-locking function, so that axial displacement of the bearing is avoided when a speed reducer vibrates, and the service life of the bearing is prolonged. The invention further provides the speed reducer using the bearing positioning structure. A thread structure is used for positioning the bearing, and thus the service life of the bearing can be prolonged.

Description

technical field [0001] The invention relates to the technical field of bearing positioning machines, in particular to a reducer and a bearing positioning structure thereof. Background technique [0002] At present, the bearing positioning adopts the spacer ring or the end cover seam to directly tighten the bearing, and its structure can refer to figure 1 As shown, 11 is the bearing, 12 is the spacer ring, and 13 is the end cover; this structure needs to adjust the spacer ring 12 according to the size of the gap during installation, and the process is more complicated; in addition, after the reducer has been running for a long time , Due to vibration and other reasons, the clearance that the bearing itself should have changes, which affects the service life of the bearing. Contents of the invention [0003] In view of this, the present invention provides a bearing positioning structure to solve the problems of bearing clearance adjustment and clearance change after operati...
