Description
Technical field
This utility model is related to a kind of ball guidance type retainer and the bearing with the retainer, and belonging to bearing should
Use technical field.
Background technology
Retainer, also known as bearing cage, refers to, and the axle for moving therewith
Part is held, to separation roller, rolling element is guided and is held it in bearing.The material of traditional bearing retainer is mainly
Steel, bakelite, ceramics, copper alloy, aluminium alloy etc., current technology developing direction are using Shooting Technique production engineering plastics
(such as：Modification of nylon) retainer.
Retainer is one of major part of bearing, and effect of the retainer in rolling bearing is to separate each
Rolling element, prevents the directly contact with rolling element；Rolling element is maintained in itself or is made which to keep together with a lasso；
Guiding rolling element is rolled on the right track；To rolling element orientation, reduce frictional force.Retainer can make friction and heat
Amount generation is reduced to minimum；And can install or unload can with the bearing of separate design when, fixed rolling element.
Rolling bearing operationally, due to sliding friction causes bearing heating and abrasion, especially in the condition of running up
Under, the effect of centrifugal inertial force exacerbates friction, abrasion and generates heat, and can cause retainer burn or rupture, cause when serious
Make bearing cisco unity malfunction.Therefore, high-performance bearing retainer is except requiring that the strength of materials is high, heat conductivity is good, friction factor
It is outer that little, wearability is good, impact flexibility is strong, density is less and linear expansion coefficient and rolling element are close, the structure to retainer
It is also the important channel for improving bearing life to carry out innovative design.
When bearing runs up, retainer is very high due to rotating speed, and the quality non-uniform phenomenon in manufacture is amplified,
Unbalance dynamic is produced, therefore, have impact on operating and the life-span of bearing.As shown in Figure 1 and Figure 2, the mode of traditional solve problem is to adopt
Be oriented to outer ring or inner ring, i.e., some steps 1 are circumferentially uniformly arranged in retainer inner ring or outer ring, in step 1 and bearing
Outer ring gap very little such that it is able to limit the bounce amplitude of retainer.But, the deficiency of traditional bearing retainer is to slide
Friction area is big, and frictional force is big, while the structure is also easily accessible the grit thing such as insert, particularly metal, so these
Factor all tends to interfere with bearing operation, produces frictional heat, and the heat for producing that rubs causes plus the heat of bearing itself generation
Retainer produces thermal expansion, and size increase makes guiding step and the gap of bearing internal external circle further reduce, or even disappears
Lose, so that retainer is increased with bearing friction power, in addition it is swollen dead, cause retainer to rupture, or even bearing burnt and combustion
The major accidents such as axle occur.
The content of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of ball guidance type retainer and with the guarantor
The bearing of frame is held, the friction and bearing between can be reduced, and reduced bearing abnormal conditions lower bearing retainer and bearing outer ring
Swollen dead situation occurs.
For achieving the above object, this utility model takes technical scheme below：A kind of ball guidance type retainer, its
It is characterised by：It includes retainer body, be distributed in the circumferential ball grooves of the retainer body and with the ball grooves phase
The guiding ball of cooperation.

It is distributed on the periphery of two collar tie beams and positioned at the crossing center of the collar tie beam and the crossbeam.
The number of the ball grooves on each collar tie beam is more than three.
The depth of the ball grooves is more than the radius for being oriented to ball.
A buckle is provided with the notch of the ball grooves.
The guiding ball is spherical or cylindrical.
Grease is coated with the ball grooves.
Coordinate for gap between the guiding ball and the ball grooves.
A kind of bearing, it is characterised in that：It includes outer ring, inner ring and the institute being arranged between the outer ring and the inner ring
State ball guidance type retainer；On the ball grooves it is each described guiding ball in the running with the outer ring
Inner surface is contacted；A bearing roller is being provided with per between crossbeam described in adjacent two, each bearing roller is respectively positioned on institute
State the position between inner surface and the inner ring outer surface.
When each guiding ball is spherical, each ball that is oriented to is contacted in point with the inner surface of the outer ring；
When each guiding ball is cylinder, each guiding ball is in linear contact lay with the inner surface of the outer ring.
Due to taking above technical scheme, which has advantages below to this utility model：1st, this utility model is provided with holding
Frame body, the ball grooves and the guiding ball being engaged with the ball grooves that are distributed in the retainer body circumference, are oriented to
Ball is contacted or linear contact lay in point with the inner surface of bearing outer ring, can be reduced frictional force, be reduced frictional heat, so as to improve this
The service life of utility model.2nd, this utility model guiding ball can increase ball guidance type retainer outer surface and axle
Gap between bearing outer-ring inner surface, reserves the space expanded with heat and contract with cold such that it is able to make axle to ball guidance type retainer
Acknowledgement of consignment row more safety and steady.3rd, ball grooves of the present utility model, in this utility model injection mo(u)lding, can be reduced because of wall thickness
The uneven and shrinkage phenomenon that produces, this utility model intensity are high, good stability.4th, this utility model is on the notch of ball grooves
A buckle is provided with, guiding ball is prevented from and is deviate from from ball grooves.5th, this utility model is coated with lubrication in ball grooves
Fat, can reduce and rub and prevent guiding ball from deviating from from ball grooves.
