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 bearing ball 103 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 wrinkled 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 the communication flow path, kerosene can be used as the oil, the oil temperature is increased to expand in volume, in a limited closed flow path, the oil path can flow towards the wrinkled rubber expansion bag 403 which is easy to deform and expand in volume under the support of the oil, because the fixing plate 402 and the side wall of the adjusting groove 301 are mutually fixed, the, the higher the bearing temperature is, the larger the expansion degree of the corrugated rubber expansion bag 403 is, the larger the pushing displacement distance of the play counteracting slide block 303 is, the larger the sliding distance of the play counteracting slide block 303 to the inner direction of the adjusting groove 301 is, namely, the less the part of the play counteracting slide block 303 exposed in 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 space size of the ball outer half channel 201 under different temperature conditions is changed, the moving space size of the bearing ball 103 can be kept in a stable state in real time, the transverse and longitudinal eliminating effects on the bearing ball 103 are achieved, and the situation that the bearing ball 103 cannot be in contact with the ball outer, The phenomenon of overlarge friction force caused by the fact that the inner half channel 202 of the ball is too close to the contact surface;
When the bearing is used, the bearing inevitably vibrates along with the transmission shaft, so that relative motion of 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 push the play counteracting slide block 303, the play counteracting slide block 303 moves towards the spring 302 under the thrust, the play counteracting slide block 303 and the folded rubber expansion bladder 403 are in fixed connection, 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 suction to the oil inlet pipe 501, the first check valve sheet 502 is of a check valve structure leading to the folded rubber expansion bladder 403, the second check valve sheet 604 is of a check valve structure leading to a direction far away from the folded rubber expansion bladder 403, and under the suction of the folded rubber expansion bladder 403, the oil path flowing direction is the heat dissipation vibration pipe 602 and the oil inlet spring pipe 606, The oil storage tank 503, the oil inlet pipe 501 and the folded rubber expansion bag 403 are followed by the play counteracting slider 303 to restore the initial position under the tension of the spring 302, the oil just sucked into the folded rubber expansion bag 403 is extruded into the oil inlet pipe 501, under the action of two one-way valves, the flow direction of the oil path is the folded 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 play counteracting slider 303, the folded rubber expansion bag 403 ceaselessly sucks and extrudes the oil, so that the oil path constantly keeps the flowing state, 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, so that 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, and the oil flowing through the heat dissipation, the high air flow velocity in the heat dissipation slot 601 can also improve the cooling effect of the bearing, and is beneficial to the maintenance of the bearing.
