Configuration bearing adjustment cover between the appearance conical surface of the tapped hole of bearing support and bearing, the outside thread that the appearance of bearing adjustment cover is complementary for the tapped hole with bearing support, the internal surface of said bearing adjustment cover is and the consistent inner conical surface of bearing appearance conical surface tapering;
Configuration one locking nut on the outside thread of bearing adjustment cover.
Further, said bearing adjustment cover (10) has regular polygon bead spanner.
Further, the inclination number of degrees of the appearance conical surface of said bearing (20) are 3 to 10 degree.
Adopt the present technique scheme, between axle and bearing support, be nested with bearing of the present invention, bearing is nested with from the outside of axle head inward, and makes the tapered plane of inclination of bearing appearance toward the outer side, and promptly little inboard, outer end is big.Between the tapped hole that bearing adjustment cover is also inserted in bearing support from outside cover and the outer ring of bearing, swivel bearing adjustment cover overlaps and will advance inwards along the adjustment of screw thread bearing; Because the internal surface of bearing adjustment cover is and the consistent inner conical surface of bearing appearance conical surface tapering; When bearing adjustment cover during along axially the advancing inward of axle, advance inward just as chock, resolve into along axial power and be parallel to the conical surface and perpendicular to two power of the conical surface; Wherein the power perpendicular to the conical surface will play squeezing action to the outer ring of bearing; Rotate tightly more, push also tightly more, make that the interior table of bearing is also big more to impacting force between the axle; The damping force that both produce is also big more, has achieved a kind of bearing with damping function thus.
Along with the swivel bearing adjustment is enclosed within the damping size that the axial position on the axle can change and regulate bearing.
After the adjustment of rotation adjustment bearing was enclosed within the position on the axle, the locking nut of screwing again by the screw thread self-locking action of locking nut, made bearing adjustment cover no longer can on bearing, do any moving axially, and guarantees that the size of damping force can not change.
Advantage of the present invention: the damping bearing device that the invention provides a kind of adjustable nodal axisn and pivot friction power; Overcome the shortcoming that present existing apparatus exists; Avoid object displacement, particularly avoid by moving down because of the self-locking inefficacy causes lowering or hoisting gear in worm gear and the worm drive, in stopping the lowering or hoisting gear descending motion by self-locking inefficacy initiation in worm gear and the worm drive; That avoids that self-locking in the worm drive lost efficacy moves down, and keeps the raising platform invariant position.This apparatus structure is simple, and is safe and reliable, practical, and the application is extensive.
