Abstract
A combined sealed bidirectional thrust bearing is composed of an inner ring, upper and lower rings, balls, a retainer and a sleeve, wherein a boss is arranged in the middle of the inner ring, the upper and lower rings are sleeved at two ends of the boss of the inner ring, raceways are arranged on end faces at two sides of the boss and corresponding end faces of the upper and lower rings, the balls and the retainer are positioned in the raceways, and the sleeve is arranged outside the upper and lower rings and fixedly connected with the sleeve. Because the upper and lower rings are sleeved on the inner ring and fixed and sealed by the sleeve, the installation is convenient, the pollution and leakage of lubricating oil can be effectively prevented, the oil filling interval time is long, the lubrication performance is good, and the service life of the bearing can be prolonged.
Description
The utility model relates to a kind of sealed type doubledirection thrust bearing.
At present, general doubledirection thrust bearing, the main fabricated structure of being made up of inner ring, upper and lower circle and rolling element is because of loosely organized, also make mistakes during installation, and seal approach is bad, lubricant oil easily pollutes, leakage loss, greasy property is bad, and is easy to wear, reduces the working life of bearing.
The purpose of this utility model is that a kind of simple in structure, good seal performance, doubledirection thrust bearing easy for installation will be provided.
The utility model is to realize like this, it is made up of inner ring, upper and lower circle, rolling element, retainer and sleeve, have boss in the middle of the inner ring, upper and lower snare is at the two ends of inner ring boss, the both sides end face of inner ring boss and the toroidal surface of upper and lower circle respective end are provided with raceway, rolling element and retainer are arranged in the raceway, and jacket casing is in the upper and lower circle outside, and is connected with upper and lower circle.Between upper and lower circle, there is an outer ring that is fixed in the sleeve in the outside, the cylndrical surface of inner ring boss, the cylndrical surface of the cylindrical form interior surface of outer ring and inner ring boss is provided with raceway, cooperates the formation radial bearing with rolling element and retainer.
The utility model is simple in structure, and upper and lower snare is at the inner ring two ends, and there is the fixing sealing of holding concurrently of sleeve the outside, can effectively prevent lubricant pollution and leakage loss, refuel and to prolong blanking time, greasy property improves, and can prolong bearing working life, because upper and lower circle is fixed by sleeve, make that the part assembling is all very convenient with adjusting, also have the advantage of thrust-bearing and radial bearing concurrently, be specially adapted to be subjected to the suspension device of axial pressure, inner ring two ends stretch out into axle sleeve, easily location and fixing on axle.
Fig. 1 is the utility model structural representation.
Fig. 2 is for entad reaching the doubledirection thrust bearing structural representation.
By shown in Figure 1, there is boss 7 centre of inner ring 3, two ends stretch out into axle sleeve, on, under enclose 4,6 kinks are at the two ends of inner ring boss 7, on the toroidal surface at inner ring boss two ends reaches, under enclose 4,6 inboard corresponding end-faces are provided with raceway, ball 1 and retainer 2 are arranged in the raceway, on, following circle, inner ring and ball and retainer constitute doubledirection thrust bearing together, on, the following circle outside is with sleeve 5, and on, following circle and sleeve are with scyewed joint, and the sleeve upper end-hole has inwardly protruded block 11, can carry out spacing to last circle 4, enclosing 6 outer end down has the block 12 of projection laterally, can under enclose 6 carry out spacing.
By shown in Figure 2, upper and lower circle 4,6 is enclosed within the middle of the inner ring 3 two ends under the boss and is fixed in the sleeve 5 with scyewed joint, a radial bearing is fixed in boss 7 outsides in the middle of the inner ring, radial bearing inner ring 8 is fixed on the cylndrical surface, the outside of inner ring boss 7 by back-up ring 10, radial bearing outer ring 9 is fixed on sleeve 5 inboards, and between upper and lower circle, the cylindrical form interior surface of the cylindrical outer surface of radial bearing inner ring 8 and outer ring 9 thereof is provided with raceway, and ball 1 and retainer are arranged in the raceway.Mind-set bearing inner race in the present embodiment also can directly be provided with raceway and substitute on inner ring boss cylindrical outer surface.
