Problems solved by technology
At the same time, during energized operation, the rotor will be subjected to electromagnetic tension from the stator, resulting in axial displacement of the rotor shaft.
All the above factors will not only cause vibration and noise to the motor, but also shorten the service life of the motor

Embodiment Construction
[0015] Such as figure 1 with figure 2 As shown, the anti-vibration mechanism for motor operation of the present invention includes a motor housing 1. The motor housing 1 is cylindrical, and its two ends are provided with end covers 6, and the inner surface of the end cover 6 is centered with bearings 3 A matching circular pit. A gland 7 is fixed at the mouth of the circular pit. A shaft hole matching the rotor shaft 5 is machined in the center of the pit bottom and the gland 7, and a bearing 3 is installed in the shaft hole. The end of the rotor shaft 5 passes through the shaft hole on the gland 7, the bearing 3 and the shaft hole at the bottom of the pit in sequence, and then protrudes out of the corresponding end cover 6. In order to avoid vibration and noise caused by friction and impact when the motor is running, and to extend the service life of the motor, a circumferential groove is machined on the inner surface of the pit wall of the circular pit, and an elastic shock-p...

The invention discloses a motor running shake prevention structure. Specifically, the motor running shake prevention structure is used to prevent a motor from shaking due to impact and friction between the outer ring of a bearing of the motor and the inner side face of a bearing seat of the bearing, caused by machining tolerance and form and location deviation when the motor is under running status. The motor running shake prevention structure comprises a motor housing, wherein end covers are arranged at two ends of the motor housing, a round pit matched with the bearing is formed in the center of the inner side face of each end cover, a press cover covers the opening portion of each round pit, shaft holes matched with a rotator shaft are respectively formed in the pit bottoms of the round pits and the centers of the end covers, the bearing is installed in the shaft holes, and the ends of the rotator shaft sequentially pass through the shaft holes in the end covers, the bearing and the shaft holes in the pit bottoms of the round pits, and then respectively stretch out of the corresponding end covers. The motor running shake prevention structure is characterized in that circumferential grooves are formed in the inner side faces of the pit walls of the round pits, and elastic shake prevention rings are arranged in the circumferential grooves. By using the motor running shake prevention structure, shakes and noise which are generated during the running process of the motor can be avoided, and use life of the motor is prolonged.
Description
Technical field [0001] The invention relates to a shockproof mechanism. Specifically, it is an anti-vibration mechanism used to prevent shock and friction between the outer ring of the bearing and the inner surface of the bearing housing due to machining tolerances and shape and position deviations. Background technique [0002] As we all know, the appearance of the motor has a long history, and it has been widely used in various industries as a power mechanism. The motor has a shell. Both ends of the shell are provided with end covers for pressing the bearing. The center of the inner surface of the end cover is processed with a circular pit for matching with the bearing. The mouths of the circular pits are all There is a gland, the bottom of the pit and the center of the gland each have a shaft hole matching the rotor shaft, a bearing is arranged in the shaft hole, and the end of the rotor shaft sequentially passes through the shaft hole on the gland, the bearing and the shaft ...
