Technical field

The present invention relates to technical field of bearings, specially a kind of bearing for being conveniently replaceable roller.

Background technique

The linear motion bearing form of early stage exactly places row's rod under row's skid plate.Modern linear motion bearing Same working principle is used, only replaces roller with ball sometimes.Simplest swivel bearing is axle sleeve bearing, it is only It is the bushing being clipped between wheel and wheel shaft.This design is then scrolled bearing substitution, exactly with many cylindrical Roller substitutes original bushing, and each rolling element is just as an individual wheel.

Existing bearing needs replacing the rollers of equivalent specifications in maintenance, and when maintenance is restricted, and narrow application range is This, proposes a kind of bearing for being conveniently replaceable roller.

Summary of the invention

It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of bearing for being conveniently replaceable roller Problem.

To achieve the above object, the invention provides the following technical scheme: a kind of bearing for being conveniently replaceable roller, including inner ring And outer ring, the second roller holding tank is fixed on the outside of the inner ring, has been fitted and connected on the outside of the second roller holding tank Roller is fixed with the first trapezoid block on the inside of the outer ring, and the inside of first trapezoid block is equipped with the first inclined surface, described outer The inside two sides of circle are respectively fixed with first annular plate and the second annular slab, the inside of the first annular plate and the second annular slab Offer sliding slot, the first annular plate is fixed with inner thread sleeve, the outside of second annular slab through have one end with The threaded rod of inner thread sleeve inside thread connection, is socketed with taper inserted block on the outside of the threaded rod, the taper inserted block Two sides are equipped with the second inclined surface to match with taper inserted block, and sliding block is slidably connected in the sliding slot, and the sliding block is fixed On the outside of the second trapezoid block, it is fixed with protruding block on the outside of second trapezoid block, is fixed with first on the inside of the protruding block Roller holding tank, on the inside of the first roller holding tank be fitted and connected on the outside of roller.

Preferably, it opens up fluted on the outside of the roller, is fixed with insertion groove on the inside of the second roller holding tank Interior scraper plate.

Preferably, grease chamber is offered in the protruding block, the grease chamber is connected with the inside of the first roller holding tank It is logical, gland is fixed on the outside of the inner ring, the side of the gland fits in the side of the second roller holding tank.

Preferably, the first inclined surface, first inclination are equipped on the outside of first inclined surface and the second trapezoid block Face is to be obliquely installed with outer ring inner wall at 45 degree of angles.

Preferably, the side of the threaded rod is fixed with retention bead.

Compared with prior art, the beneficial effects of the present invention are: the bearing pushes away retention bead by rotary screwing thread bar Mantle shape inserted block is mobile, so that the first trapezoid block and the second trapezoid block hold the first roller holding tank, the second roller close to movement It receives slot and roller takes out jointly, after the first roller holding tank to match each other, the second roller holding tank and the roller that more renew, and It rotates clockwise threaded rod, pushes taper inserted block mobile, so that the first trapezoid block and the second trapezoid block be far from mobile, thus to the One roller holding tank is clamped, complete replacement movement, can more sliding different size of roller, improve bearing adapter, be convenient for The maintenance of bearing.
