Description
Technical field：
The present invention relates to a kind of angular contact ball bearing, more particularly to a kind of new angular contact ball bearing and its processing technology.
Background technology：
At present, in Automatic manual transmission industrial scale, in order to improve production efficiency reduction production cost target, some production dress
It is standby to require must to be fulfilled under the larger working condition of high temperature, high speed, power of toppling；And angular contact ball bearing limit velocity is high, and can
Matched, favored using bearing radial load, axial force, tilting moment load by numerous designers with independent assortment：Work as operating temperature
During more than 80 degree, the speed of service is higher, in the case of power of toppling is larger, if there is retainer using the angular contact ball of existing structure
Serious wear, vibrations cause greatly the phenomenon of bearing frequent breakage.
With going deep into for research, we carry out network analysis to existing angular contact structure, to search existing standard structure class
The limitation that type design is present；When running temperature is more than 80 °C, angular contact ball keeps frame material to use copper alloy, and its is heavy
Amount is larger, and the limitation that existing angular contact ball bearing normal structure type design is present, which seems, to be become apparent from, and is made a concrete analysis of as follows：1、
Cone ball guides retainer structure, is not suitable with a high speed, the larger operating mode of tilting moment.2nd, ball guiding retainer structure, is not suitable with height
Speed.3rd, interior guiding retainer structure, is not suitable with high speed, large axial force.4th, retainer structure is guided outside single fulcrum, transported at a high speed
OK, centrifugal force easily causes vibrations without balanced action point, causes the realization easy to wear of retainer pocket hole.
The content of the invention：
The technical problems to be solved by the invention are：Overcome the deficiencies in the prior art there is provided one kind it is reasonable in design, do not increasing axle
The new angular contact ball bearing and its processing technology of service life can be improved by holding under cost.
The technical scheme is that：
A kind of new angular contact ball bearing, including outer ring, inner ring, rolling element and retainer, the outer ring fill the outer end of ball cone
One outer ring face of cylinder is set on internal diameter, and the external diameter of the retainer non-stress side sets a retainer cylinder boss, described
Intrinsic guide clearance is kept between retainer cylinder boss and the outer ring face of cylinder.
N axial diversion lubrication groove is set on the boss of the retainer face of cylinder, and to cool down raceway and guide surface, n is
Natural number more than 1.
A kind of processing technology of new angular contact ball bearing, ball cone is filled in the outer ring of existing conventional angular contact ball bearing
One outer ring face of cylinder is set on the internal diameter of outer end, to balance the centrifugal force of the retainer of rotation at a high speed；In existing conventional angular contact
On the external diameter of the retainer non-stress side of ball bearing set a retainer cylinder boss, the retainer cylinder boss with it is described
Intrinsic guide clearance is kept between the face of cylinder of outer ring, to limit the movement locus of the retainer, prevent the retainer from
Deviate centre of gyration position.
N axial diversion lubrication groove is set on the boss of the retainer face of cylinder, plays and cools down raceway and guide surface
Effect, improves the bearing limit speed of service, and n is greater than 1 natural number.
The beneficial effects of the invention are as follows：
1st, the present invention processes a face of cylinder in outer ring dress ball cone, to balance the centrifugal force of the retainer of rotation at a high speed；Protecting
Holding frame non-stress side external diameter increases the face of cylinder boss guide clearance intrinsic with the holding of the outer ring face of cylinder, to limit retainer
Movement locus, prevent retainer from deviateing centre of gyration position, service life can be improved in the case where not increasing bearing cost.
2nd, the present invention processes n R water conservancy diversion lubrication groove on the retainer face of cylinder, plays the work of cooling raceway and guide surface
With the raising bearing limit speed of service.
3rd, the present invention makes the new application field of the adaptation of angular contact ball bearing, in high-speed aluminum foil rolling mill industry, super-pressure pump
Promoted the use of already, and obtained the universal favorable comment of user, its applicability is very high, it is easy to promotion and implementation, with good economic benefit.
