Description
[technical field]
This utility model relates to the technical field of bearing, particularly the technical field of a kind of easily detachable bearing.
[background technology]
Bearing is commonly used for common parts in the middle of axis transmission structure, bearing effect in driven off by shaft process mainly prevent power transmission shaft in the process used with structure in the middle of end face rub, reduce the frictional resistance that power transmission shaft is in use suffered, it is ensured that the service life of power transmission shaft and efficiency of transmission.Common bearing is by being connected with the inner ring of bearing by power transmission shaft, and between inner ring and outer ring, place some balls and retainer, inner ring is driven to rotate by power transmission shaft, and outer ring remains stationary as, ball and the logical motion of retainer one is made by the rotation of bearing inner race, rolling friction under same case is compared with sliding friction, and frictional force is less.Thus serving the effect reducing friction.And during bearing operation, have the effect of force of rolling friction between inner ring and the outer ring of ball and bearing, although frictional force is less always, but the running time of bearing is longer, the parts in bearing easily wear and tear.The bearing of abrasion needs to disassemble from machinery to be replaced.Mostly it is arranged between axle sleeve and axle due to bearing, during dismounting, is difficult to find stress point, dismounting inconvenience.And existing bearing is mostly integrated encapsulating structure, can only selecting completely to split out, dismantling when working place is not enough extremely wastes time and energy, and result in the benefit of production and is substantially reduced.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of easily detachable bearing is proposed, bearing can be made to take out in the little space between axle sleeve and axle easily, the bearing of lower abrasion is quickly easily removed under open space, bearing removal suitable in big-and-middle-sized machinery changes maintenance, it is effectively increased the efficiency of maintenance, it is ensured that being normally carried out in order of production.
For achieving the above object, the utility model proposes a kind of easily detachable bearing, including bearing inner race, bearing outer ring, ball, tensioner sealing ring, upper maintenance, encloses, lower maintenance, encloses, described bearing inner race is arranged in bearing inner race, the lateral wall of described bearing inner race is provided with the first tensioner draw-in groove, the medial wall of described bearing outer ring is provided with the second tensioner draw-in groove, described ball quantity has some, described ball be shaped as ellipse, described ball is uniformly circumferentially positioned between bearing inner race and bearing outer ring, described upper maintenance circle and lower maintenance circle are arranged between bearing inner race and bearing outer ring, described tensioner sealing ring is arranged between bearing inner race and bearing outer ring.
As preferably, the quantity of described first tensioner draw-in groove has two, described first tensioner draw-in groove is arranged on the two ends, side of bearing inner race, the position of described second tensioner draw-in groove and the first tensioner draw-in groove is left and right one-to-one relationship, and width and the depth of groove of described second tensioner draw-in groove and the first tensioner draw-in groove are all identical.
As preferably, the described upper shape size keeping enclosing with lower maintenance is enclosed is all identical, the described upper bottom keeping circle is provided with ball groove, in described upper the second tensioner draw-in groove and the first tensioner draw-in groove that keep circle to be arranged on upper end, in described lower the second tensioner draw-in groove and the first tensioner draw-in groove that keep circle to be arranged on lower end.
As preferably, described tensioner sealing ring is arranged in the second tensioner draw-in groove and the first tensioner draw-in groove, described tensioner sealing ring is arranged on maintenance circle and lower maintenance encloses outside, and the lateral wall of described bearing inner race is smooth facing directly, and the medial wall of described bearing outer ring is smooth facing directly.
As preferably, the width of described first tensioner groove is the twice of depth of groove, and the thickness of described tensioner sealing ring is upper keep circle thickness four times, and described tensioner sealing ring is identical with the width of the first tensioner draw-in groove with the gross thickness of upper maintenance circle.
The beneficial effects of the utility model: this utility model is by by bearing inner race, bearing outer ring, ball, tensioner sealing ring, upper maintenance, encloses, lower maintenance, encloses, second tensioner draw-in groove, first tensioner draw-in groove combines, through optimum experimental, the upper effect keeping circle and lower maintenance circle combination to serve retainer, simultaneously facilitate dismounting, after elastic tensioning sealing ring takes out, the ship clearance of the first tensioner draw-in groove can be taken out conveniently maintenance circle and lower maintenance encloses, then oval ball can be poured out, bearing outer ring and bearing inner race natural separation come, finally can dismantle to opening with bearing outer ring and bearing inner race.This utility model can make bearing take out in the little space between axle sleeve and axle easily, the bearing of lower abrasion is quickly easily removed under open space, bearing removal suitable in big-and-middle-sized machinery changes maintenance, is effectively increased the efficiency of maintenance, it is ensured that being normally carried out in order of production.
Feature of the present utility model and advantage will be described in detail in conjunction with accompanying drawing by embodiment.
