Description
Technical Field
The utility model relates to an auxiliary device of bearing mainly relates to a preloading device of footstep bearing end face spring.
Background
Tapered rollers are mostly adopted as thrust bearings on rolling mill roll equipment in the field of ferrous metallurgy, at present, a device with a pre-tightening spring is mostly adopted on the end face of a bearing, the function can effectively eliminate the defects of insufficient pre-tightening during manual installation and the effect of automatically righting a non-load row ferrule in the using process of the bearing, and plays a key role in the performance and the service life of the bearing, but most of the prior pre-tightening springs adopted by the bearing with the pre-tightening device are difficult to install and easy to clamp, and the phenomena of insufficient pre-tightening and failure can also occur due to sinking.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the background art, the utility model aims to provide a preloading device of a thrust bearing end face spring.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a pre-tightening device for an end face spring of a thrust bearing is arranged in an end face hole of an outer ring; the pre-tightening device is provided with a locking ring in interference fit with the end surface hole of the outer ring; the outer end face of the locking ring and the opening face of the end face hole are on the same plane; the outer end surface of the locking ring is provided with an annular boss protruding inwards; a stop push rod is arranged in the locking ring, and one end of the stop push rod extends out of the locking ring; the stop push rod is provided with a cylinder with the diameter smaller than the inner diameter of the annular boss; the middle part of the cylinder is provided with an annular bulge protruding outwards; the outer diameter of the annular bulge is larger than the inner diameter of the annular boss, and the annular bulge is positioned on the inner side of the annular boss; a limiting surface for limiting the stop push rod is formed on the inner wall surface of the annular boss; one side end face of the annular boss is matched with the inner wall face of the annular boss, and a pre-tightening spring sleeved on the stop push rod is arranged between the other side end face of the annular boss and the bottom face of the end face hole of the outer ring.
One end of the outer diameter surface of the locking ring is provided with a slope which is convenient for installation in interference fit.
The utility model provides a thrust bearing end face spring's preloading device, spring preloading device's locking ring are the stamping workpiece, and the installation is simple during the interference fit, and locking push rod and pretension spring during operation have the effect of rightting to it, and difficult card is dead, the effectual phenomenon that improves spring preloading device early failure.
