The utility model further provides that: the damping device is characterized in that a baffle ring is bent towards the left side wall of the outer ring on the left side wall of the outer shell, a resonance groove communicated with the resonance cavity is formed between the inner peripheral wall of the baffle ring and the left side wall of the outer ring, and a matching ring is bent towards the resonance groove on the left side wall of the damping ring.
The technical scheme is beneficial in that: the baffle ring can limit the movement of the damping ring, so that the damping ring can normally bear the resonance acting force transmitted by the outer ring.
The utility model further provides that: the locating piece includes the holding ring, the holding ring inner wall contacts with outer lane right side wall and shell right side wall respectively and sets up, a plurality of locating holes have been seted up on the holding ring, the mating holes has all been seted up to corresponding every locating hole position on the outer lane right side wall, every equal threaded connection has positioning bolt on the locating hole, every positioning bolt all sets up with the mating holes screw thread fit that is adjacent and corresponds respectively.
The technical scheme is beneficial in that: the setting of holding ring can be with keeping off the ring and make up and carry out spacingly to the damping ring, avoids its aversion when bearing high-speed operation, and the locating hole is connected through positioning bolt with the mating hole simultaneously, and then makes the holding ring can be connected with the outer lane, avoids the holding ring to break away from the outer lane and leads to the damping ring not to receive the holding ring restriction.
The utility model further provides that: grooves are formed in the outer peripheral wall and the inner peripheral wall of the damping ring, the two grooves are arranged close to the right side wall of the damping ring, the outer peripheral wall of the outer ring and the inner peripheral wall of the outer shell are combined with the grooves adjacent to each other to form a grease storage groove, and solid grease is filled in the grease storage groove.
The technical scheme is beneficial in that: the solid grease is filled in the grease storage groove in the technology, and when the bearing runs at a high speed, the solid grease in the grease storage groove is converted into liquid grease and coated on the inner peripheral wall surface and the outer peripheral wall surface of the damping ring along the gap, so that the influence on the bearing rotating speed and the service life due to overlarge friction torque between the damping ring and the outer shell and between the damping ring and the outer ring is avoided.
