Structure for preventing motor bearing from going to outer ring

Abstract

The invention relates to a structure for preventing a motor bearing from going to an outer ring. The bearing is installed on a motor shaft, a bearing inner cover is installed on the motor shaft on the inner side of the bearing, and a bearing outer cover is arranged on the outer side of the bearing. An elastic retaining ring is installed on the motor shaft of the outer side of the bearing, and an oil thrower is arranged between the elastic retaining ring and the bearing. The inner end face of the oil thrower abuts against the outer end face of the inner ring of the bearing, and the outer end face of the oil thrower abuts against the inner end face of the elastic retaining ring. A bushing is connected to the outer ring of the bearing in a sleeved mode, the inner end face of the bushing abuts against the outer end face of the bearing inner cover, and the outer end face of the bushing abuts against the inner end face of the bearing outer cover. An end cover is connected to the bushing in a sleeved mode, and the bearing inner cover, the end cover and the bearing outer cover are fixed to form a whole through bolts. The structure for preventing the motor bearing from going to the outer ring is simple, compact and reasonable in structure, capable of effectively solving the problem that the bearing goes to the outer ring, and capable of greatly prolonging the service life of the motor bearing.

Description

technical field [0001] The invention relates to a motor bearing structure, in particular to a structure capable of preventing the motor bearing from running out of the outer ring. Background technique [0002] As the connection between the static part and the rotating part of the motor, the quality of the bearing determines whether the motor can run continuously, and even affects the life of the motor. In recent years, the problem of running circles of motor bearings has become increasingly obvious, but in many cases there is no reasonable measure to solve it. [0003] There are two types of bearing rings: one is the outer ring of the bearing, that is, the relative displacement between the outer ring of the bearing and the bearing chamber; the other is the inner ring of the bearing, that is, the relative displacement between the inner ring of the bearing and the journal . Under normal circumstances, there is no relative displacement between the outer ring, inner ring and j...
