Abstract
The utility model discloses the nonmetal crown type retainer of a kind of high-speed bearing, comprise keeper body, the outer circumferential face of described keeper body is provided with some external diameter obliquity structures, some external diameter obliquity structures are arranged in the outer circumferential face outward edge position of keeper body, some external diameter obliquity structures are equally arranged, keeper body is provided with retainer pocket hole, retainer pocket hole is provided with steel ball, the top in retainer pocket hole is provided with retainer fore shaft, retainer fore shaft is provided with some fore shaft obliquity structures, the identical fore shaft obliquity structure of two shape sizes is provided with between adjacent two external diameter obliquity structures.The utility model adds the precision of retainer fore shaft, adds the intensity of fore shaft, increases fore shaft obliquity structure simultaneously and keeper body can also be made to arrive the distance increase in retainer pocket hole, strengthen the structural strength of retainer fore shaft; Its external diameter obliquity structure decreases the probability that keeper body contacts with bearing outside collar.
Description
Technical field
The utility model relates to a kind of retainer, particularly the nonmetal crown type retainer of a kind of high-speed bearing.
[
background technique]
In prior art, as patent CN201120003660.7 discloses a kind of reinforced high polymer retainer, it can strengthen the confining force of retainer body, extends the working life of retainer.The utility model comprises retainer body, retainer body is provided with reinforcing mechanisms, reinforcing mechanisms is arranged on retainer body interior or is arranged on retainer body exterior, and the cross section of reinforcing mechanisms is circular, square or " work " font, reinforcing mechanisms is provided with four eyed spring or banner bar.This retainer intensity difference, and structure is insecure.
[model utility content]
Main purpose of the present utility model is to provide a kind of precision adding retainer fore shaft, add the intensity of fore shaft, increasing fore shaft obliquity structure can also make keeper body arrive the distance increase in retainer pocket hole simultaneously, strengthens the nonmetal crown type retainer of high-speed bearing of the structural strength of retainer fore shaft.
For achieving the above object, the technological scheme that the utility model is taked is:
The nonmetal crown type retainer of a kind of high-speed bearing, comprise keeper body, the outer circumferential face of described keeper body is provided with some external diameter obliquity structures, some external diameter obliquity structures are arranged in the outer circumferential face outward edge position of keeper body, some external diameter obliquity structures are equally arranged, keeper body is provided with retainer pocket hole, retainer pocket hole is provided with steel ball, the top in retainer pocket hole is provided with retainer fore shaft, retainer fore shaft is provided with some fore shaft obliquity structures, is provided with the identical fore shaft obliquity structure of two shape sizes between adjacent two external diameter obliquity structures.
Further, described external diameter obliquity structure is skewed.
Further, described fore shaft obliquity structure is skewed.
Further, fore shaft is positioned at the inside of keeper body.
Compared with prior art, the utility model has following beneficial effect: the outer circumferential face due to described keeper body is provided with some external diameter obliquity structures, some external diameter obliquity structures are arranged in the outer circumferential face outward edge position of keeper body, some external diameter obliquity structures are equally arranged, its external diameter obliquity structure decreases the probability that keeper body contacts with bearing outside collar.Keeper body is provided with retainer pocket hole, retainer pocket hole is provided with steel ball, the top in retainer pocket hole is provided with retainer fore shaft, retainer fore shaft is provided with some fore shaft obliquity structures, the identical fore shaft obliquity structure of two shape sizes is provided with between adjacent two external diameter obliquity structures, so add the precision of retainer fore shaft, add the intensity of fore shaft, fore shaft obliquity structure can make retainer fore shaft excess stock remove, the impact that the excess stock reducing retainer fore shaft runs up on steel ball, increasing fore shaft obliquity structure can also make keeper body arrive the distance increase in retainer pocket hole simultaneously, strengthen the structural strength of retainer fore shaft, ensure that steel ball can not come off.
[
accompanying drawing explanation]
Fig. 1 is the structural representation of the nonmetal crown type retainer of the utility model high-speed bearing.
Fig. 2 is A-A sectional drawing in Fig. 1.
[
embodiment]
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As shown in Figures 1 and 2, the nonmetal crown type retainer of a kind of high-speed bearing, comprise keeper body 1, the outer circumferential face of keeper body 1 is provided with some external diameter obliquity structures 5, some external diameter obliquity structures 5 are arranged in the outer circumferential face outward edge position of keeper body 1, some external diameter obliquity structures 5 are equally arranged, keeper body 1 is provided with retainer pocket hole 2, retainer pocket hole 2 is provided with steel ball, the top in retainer pocket hole 2 is provided with retainer fore shaft 3, retainer fore shaft 3 is provided with some fore shaft obliquity structures 4, the identical fore shaft obliquity structure 4 of two shape sizes is provided with between adjacent two external diameter obliquity structures 5, , fore shaft obliquity structure 4 in skewed, external diameter obliquity structure 5 is in skewed.
The nonmetal crown type retainer of the utility model high-speed bearing, add the precision of retainer fore shaft, add the intensity of fore shaft, fore shaft obliquity structure 4 can make retainer fore shaft 3 excess stock remove, the impact that the excess stock reducing retainer fore shaft 3 runs up on steel ball, increasing fore shaft obliquity structure 4 can also make keeper body 1 increase to the distance in retainer pocket hole 2 simultaneously, strengthens the structural strength of retainer fore shaft 3, ensures that steel ball can not come off.
The nonmetal crown type retainer of the utility model high-speed bearing, decrease the probability that retainer contacts with bearing outside collar, because in the process of running up, due to the effect of centrifugal force, the claw of keeper body 1 there will be the phenomenon slightly expanded outwardly, cause the touching of keeper body 1 and bearing outside collar, have a strong impact on the working life of bearing, the effect of external diameter obliquity structure 5 is the thickness of the claw changing keeper body 1, formed and both avoided the touching with bearing outside collar, remain the structural strength of keeper body 1 simultaneously.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
