Description
Technical field
The utility model relates to a kind of wheel hub layer rolling device, belongs to wheel nave technical field.
Background technology
Current, the carriage of wheel nave mostly is ball and axle bumper, axle bowl combinationally use, because vehicle-mounted varies in weight, different with the wearing and tearing of axle bumper, axle bowl to ball, so it uses unstable, needs often to change; Existing use individual layer ball bearing of main shaft uses as carriage, but its area of thrust surface are linear contact, and slideway is easy to wear, and period of service is short, also needs frequently to change.
Summary of the invention
In order to overcome the deficiency of above-mentioned technology, the utility model provides a kind of wheel hub layer rolling device, and this wheel hub layer rolling device adopts double-deck taper roller to increase slideway area of thrust surface, extends replacing construction.
The utility model solves the technical scheme that its technical matters adopts: be the cylinder of hollow in wheel hub, in it, two ends are provided with the boss limiting outer bearing, in wheel hub, two ends are equipped with outer bearing respectively, the right-hand member of outer bearing internal layer is provided with screw thread, the right-hand member of outer bearing internal layer is equipped with the plain cushion one that diameter is greater than inner sleeve, the right side of plain cushion one is equipped with jam nut, and jam nut is provided with through hole, is equipped with spring cotter one in through hole; In outer bearing, two ends are equipped with inner sleeve respectively, and be equipped with the boss limiting outer bearing outside inner sleeve, in inner sleeve, two ends are equipped with internal layer bearing respectively, be equipped with the boss of restriction internal layer bearing, be equipped with axis in internal layer bearing in inner sleeve; The bolt that passes on left of wheel hub is equipped with left end cap, and the outer rim of left end cap is identical with the outer rim of wheel hub, and left end cap center is provided with the through hole that diameter is greater than axis; Axis left end is provided with spacing boss restriction internal layer bearing, and axis right-hand member is provided with the screw rod that diameter is less than axis, and plain cushion two is positioned on the internal layer of internal layer bearing, and spindle nut screws on screw rod, and spindle nut is provided with through hole, is equipped with spring cotter two in through hole; The right-hand member of wheel hub is equipped with right end cap by bolt.
The beneficial effects of the utility model are: owing to adopting double-decker, bearing capacity is large, weares and teares little, increases the service life of wheel hub, saves cost of repair.
