in the use process of the bearing, because the temperature of the bearing is gradually increased under the influence of friction force, the inner ring and the outer ring of the bearing are heated to expand, the friction force borne by the ball bearing 103 of the bearing is greatly enhanced, and the normal use effect of the bearing is seriously affected, in the invention, along with the increase of the temperature of the bearing, the inner ring 101 and the outer ring 102 of the bearing are heated to expand, meanwhile, the outer ring 102 of the bearing can transmit heat to the corrugated rubber expansion bag 403, the oil inlet pipe 501, the oil storage tank 503, the oil inlet spring pipe 606, the heat dissipation vibration pipe 602 and the oil outlet pipe 603 in a communication flow path, the oil can use kerosene, the oil temperature is increased to expand in volume, in a limited closed flow path, an oil path can flow towards the corrugated rubber expansion bag 403 which is easy to deform and expand, the volume of the corrugated rubber expansion bag 403 is expanded under the support of the oil, because the fixing plate 402 and the side wall of the adjusting groove 301 are mutually fixed, the wrinkled rubber expansion bag 403 pushes the play counteracting slide block 303 towards the spring 302, the higher the bearing temperature is, the larger the expansion degree of the wrinkled rubber expansion bag 403 is, the larger the pushing displacement distance to the play counteracting slide block 303 is, the larger the sliding distance of the play counteracting slide block 303 towards the inner direction of the adjusting groove 301 is, that is, the smaller the part of the play counteracting slide block 303 exposed inside the ball outer half channel 201 is, under the condition that the bearing inner ring 101 and the bearing outer ring 102 are expanded, the bearing ball 103 can obtain enough moving space, the condition that the bearing cannot be normally used due to overlarge friction force is avoided, the position change of the play counteracting slide block 303 is controlled by using oil temperature, the size of the ball outer half channel 201 under different temperature conditions is further changed, the size of the moving space of the bearing ball 103 can be kept in a stable state in real time, and the effect of eliminating transverse and longitudinal plays a role on the bearing ball 103, the bearing ball 103 can be synchronously ensured not to be attached too close to the ball outer half channel 201 and the ball inner half channel 202 to cause the phenomenon of overlarge friction force;
when the bearing is in use, the bearing inevitably vibrates along with the transmission shaft, so that relative motion with high frequency and low displacement is generated between the bearing ball 103 and the play counteracting slide block 303, the relative motion causes the bearing ball 103 to generate a pushing action on the play counteracting slide block 303, the play counteracting slide block 303 moves towards the spring 302 under the pushing force, the play counteracting slide block 303 and the folded rubber expansion bladder 403 are in a fixed connection relationship, the play counteracting slide block 303 drives the folded rubber expansion bladder 403 to stretch and expand, so that the folded rubber expansion bladder 403 generates a suction force on the oil inlet pipe 501, the first check valve sheet 502 is a check valve structure leading to the folded rubber expansion bladder 403, the second check valve sheet 604 is a check valve structure leading to a direction far away from the folded rubber expansion bladder 403, so that under the suction of the folded rubber expansion bladder 403, the oil path flow directions are the heat dissipation vibration pipe 602, the oil inlet spring pipe 606, the oil storage tank 503, the oil inlet pipe 501 and the folded rubber expansion bladder 403, the clearance offsetting slide block 303 recovers the initial position under the tension action of the spring 302, oil which is just sucked into the wrinkled rubber expansion bag 403 is extruded into the oil inlet pipe 501, under the action of the two one-way valves, the flowing direction of the oil path at this time is the wrinkled rubber expansion bag 403, the oil inlet pipe 501, the oil outlet pipe 603, the oil outlet spring pipe 605 and the heat dissipation vibration pipe 602, under the action of the incessant vibration displacement of the clearance offsetting slide block 303, the wrinkled rubber expansion bag 403 ceaselessly sucks and extrudes the oil, so that the oil path keeps flowing state all the time, the heat dissipation vibration pipe 602 is elastically installed on the side wall of the heat dissipation groove hole 601 through the oil outlet spring pipe 605 and the oil inlet spring pipe 606, the heat dissipation vibration pipe 602 is easy to swing along with the vibration of the bearing, the heat dissipation vibration pipe 602 ceaselessly swings to accelerate the peripheral air flow rate, so that the oil flowing through the heat dissipation vibration pipe 602 can be efficiently cooled, the high air flow speed in the heat dissipation slot 601 can also improve the cooling effect of the bearing, which is beneficial to the maintenance of the bearing.
