Description
Technical Field
The utility model relates to the technical field of electromechanical equipment, in particular to a stop structure for an outer ring of a motor bearing.
Background
In general, a motor is high-speed rotating equipment, more than 50% of faults of the motor occur in a bearing, and the bearing is worn out to cause heating loss of the bearing, which is the most common phenomenon in bearing faults, because the bearing outer ring is in transition fit with a bearing seat hole on a motor end cover, and in order to prevent the bearing play from becoming smaller, clearance fit is usually adopted in actual processing, namely the bearing seat hole is slightly larger than the bearing outer ring so as to reserve the space for outward expansion of the bearing outer ring in rotation, so that the phenomenon of the outer ring is generated due to various reasons when the bearing rotates at high speed, and in the prior art, no particularly good solution exists for the fault of the outer ring of the bearing of the motor.
Chinese patent document CN201925353U (an anti-slip structure of a bearing outer ring) discloses a bearing outer ring stop structure, which is characterized in that a stop groove surrounding the outer ring is provided in the middle of the outer edge surface of the bearing outer ring, circular widening points are provided at intervals in the stop groove, and nylon is injected into the stop groove and the circular widening points to form the anti-slip structure of the bearing outer ring. Chinese patent document CN2763621Y (a structure for preventing bearing outer ring from slipping) discloses another bearing outer ring stop structure, which has matching grooves in the upper axial direction of the bearing seat inner hole and the outer axial direction of the rolling bearing, and is combined to form a closed cavity, and a locating pin matched with the cavity is installed in the cavity. Both the two technical schemes are to reform the outer ring of the bearing, so that the strength of the bearing can be weakened, the processing difficulty and working procedures of the bearing can be increased, and the production cost can be increased.
