Abstract

The utility model relates to a bearing, including bearing outer loop, bearing inner ring, holder and a plurality of ball, be equipped with the crescent that suits with the ball on bearing outer loop, the endocyclic inner wall of bearing, the ball setting is installed in the crescent between bearing outer loop and bearing inner ring and through the holder, holder side both ends fixedly connected with is used for holding the V type annular of lubricated liquid, is equipped with a plurality of oil cavities on the V type annular, V type annular top is equipped with the sealing washer. The utility model has the characteristics of inside preventing that the dust from getting into bearing, can self -supporting lubrication, prevent that the steel ball from rustting, wearing and tearing etc.

Description

Bearing
Technical field
The utility model relates to technical field of bearings, particularly a kind of bearing.
Background technique
Ball bearing is the most frequently used a kind of bearing, common ball bearing is made up of inner ring, outer ring, one group of steel ball, because its structure is simple, easy to use, therefore produce the most general, but during normal use, the lubrication of bearing is very important, the insufficient meeting of bearing lubrication causes wearing and tearing, can bearing lubrication undue, can resistance be increased.After bearing is installed, outer ring and bearing support interference fit, in use, outer ring stressed larger time, the situation of the circumferential displacement in outer ring can be there is, affect the stability of bearing working like this, shorten the working life of bearing.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one and prevents dust from entering Bearing inner, self-supporting can lubricate, prevents steel ball from getting rusty, the bearing of wearing and tearing.
Realize the technical solution of the utility model as follows:
Bearing, comprises outer race, bearing inner ring, retainer and multiple ball, and the inwall of described outer race, bearing inner ring is provided with the crescent adapted with ball, and ball to be arranged between outer race and bearing inner ring and to be arranged in crescent by retainer; Two ends, described retainer side are fixedly connected with the V-type annular groove for holding Lubricants, and V-type annular groove is provided with multiple lubrication hole, are provided with seal ring above described V-type annular groove.
Have employed above-mentioned scheme, the Lubricants first in V-type annular groove flows to ball by lubrication hole, and ball can reduce and the friction of outer race with inner ring in morning in week under the effect of Lubricants, prevents ball from getting rusty and weares and teares; When bearing working, Lubricants in V-type annular groove because centrifugal effect is flowed out from lubrication hole, Lubricants can be stay on ball, also can be outer race or bearing inner ring inwall on, final is all can make to be lubricated between ball and outer race or bearing inner ring, realizes the function of selflubricating; Seal ring not only can prevent dust from entering Bearing inner, causes ball to damage, effectively extends the working life of bearing, V-type groove can also be sealed, prevent Lubricants from spilling, pollute; In addition seal ring, between bearing inner ring and outer race formed a sealed cavity, Lubricants seepage can be prevented, improve lubricating efficiency.
Described seal ring two ends are connected on outer race and bearing inner ring, and outer race and bearing inner ring are respectively equipped with the connecting groove adapted with seal ring, seal ring are also provided with the sealing block adapted with V-type annular groove.
Have employed above-mentioned scheme, seal ring and outer race, bearing inner ring can be connected firmly, and not easily come off from bearing, and V-type groove can seal by sealing block, prevents Lubricants from outwards spraying.
The outer wall of described outer race is provided with multiple groove, and multiple groove forms the round structure with outer race concentric, installs non-slipping block in groove, this non-slipping block outwardly outstanding higher than the outer wall surface of outer race.
Have employed above-mentioned scheme, when mounted, add the friction factor of bearing and assembling set, can prevent it from producing position during work and loosen, the phenomenons such as displacement, strengthen soundness is installed, improve working stability.
The surface of described crescent is coated with graphite layer.
Have employed above-mentioned scheme, when bearing initially uses, Lubricants lubrication, less than the joint of ball and outer race, bearing inner ring, so initially can be lubricated by graphite layer, is convenient to initial rolling, prevents to wear and tear.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged view of A in Fig. 1;
Fig. 3 is the enlarged view of B in Fig. 1;
In accompanying drawing, 1 is outer race, and 11 is groove, and 2 is bearing inner ring, 3 balls, and 4 is retainer, and 5 is V-type annular groove, and 51 is lubrication hole, and 6 is seal ring, and 61 is sealing block, and 62 is connecting groove, and 7 is non-slipping block, and 8 is crescent.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As Fig. 1 to Fig. 3, bearing, comprise outer race 1, bearing inner ring 2, retainer 4 and multiple ball 3, the inwall of described outer race 1, bearing inner ring 2 is provided with the crescent 8 adapted with ball 3, and ball 3 to be arranged between outer race 1 and bearing inner ring 2 and to be arranged in crescent 8 by retainer, and the surface of crescent 8 is coated with graphite layer; Two ends, described retainer 4 side are fixedly connected with the V-type annular groove 5 for holding Lubricants, V-type annular groove 5 is provided with multiple lubrication hole 51, seal ring 6 is provided with above described V-type annular groove 5, seal ring 6 two ends are connected on outer race 1 and bearing inner ring 2, outer race 1 and bearing inner ring 2 are respectively equipped with the connecting groove 62 adapted with seal ring 6, seal ring are also provided with the sealing block 61 adapted with V-type annular groove.
The outer wall of outer race 1 is provided with multiple groove 11, and multiple groove 11 forms the round structure with outer race concentric, installs non-slipping block 7 in groove 11, this non-slipping block outwardly outstanding higher than the outer wall surface of outer race.
