Abstract
The utility model discloses a kind of new angular contact ball bearing, and it includes outer ring, inner ring, rolling element and retainer, sets the outer ring face of cylinder on the outer end internal diameter of outer ring dress ball cone, the centrifugal force of the retainer rotated at a high speed with balance；External diameter in the retainer non-stress side sets a retainer cylinder boss, intrinsic guide clearance is kept between the retainer cylinder boss and the outer ring face of cylinder, to limit the movement locus of the retainer, prevent the retainer from deviateing centre of gyration position.N axially point cold convective tank is set on the boss of the retainer face of cylinder, plays a part of cooling down raceway and guide surface, improves the bearing limit speed of service.The utility model makes the new application field of the adaptation of angular contact ball bearing, and in high-speed aluminum foil rolling mill industry, super-pressure pump was promoted the use of already, obtained the universal favorable comment of user, and its applicability is very high, implementation easy to spread.
Description
Technical field：
A kind of angular contact ball bearing is the utility model is related to, more particularly to a kind of new angular contact ball bearing.
Background technology：
At present, in Automatic manual transmission industrial scale, production cost target is reduced in order to improve production efficiency, some life
Production equipment Requirement must is 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 be matched with independent assortment, favored using bearing radial load, axial force, tilting moment load by numerous designers：Work as work
When temperature is more than 80 degree, the speed of service is higher, in the case of power of toppling is larger, is protected if being existed using the angular contact ball of existing structure
Hold frame serious wear, the big phenomenon for causing bearing frequent breakage of vibrations.
With going deep into for research, we carry out network analysis to existing angular contact structure, to search existing standard structure class
Limitation existing for type design；When running temperature is more than 80 °C, angular contact ball keeps frame material to use copper alloy, and its is heavy
Measure larger, limitation existing for the design of existing angular contact ball bearing normal structure type, which seems, to be become apparent from, and concrete analysis is 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, is 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.
Utility model content：
Technical problem to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided it is a kind of it is reasonable in design,
The new angular contact ball bearing of service life can be improved by not increasing under bearing cost.
The technical solution of the utility model is：
A kind of new angular contact ball bearing, including outer ring, inner ring, rolling element and retainer, ball cone is filled in the outer ring
Outer end internal diameter on set the outer ring face of cylinder, with balance at a high speed rotation retainer centrifugal force；It is non-in the retainer
The external diameter of stress side sets a retainer cylinder boss, is kept between the retainer cylinder boss and the outer ring face of cylinder
Intrinsic guide clearance, to limit the movement locus of the retainer, prevent the retainer from deviateing 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 utility model are：
1st, the utility model processes a face of cylinder in outer ring dress ball cone, the centrifugation of the retainer rotated at a high speed with balance
Power；In retainer non-stress side, external diameter increases the face of cylinder boss guide clearance intrinsic with the holding of the outer ring face of cylinder, with limit
The movement locus of retainer processed, retainer is seted to be improved from deviateing centre of gyration position in the case where not increasing bearing cost
Service life.
2nd, the utility model processes n R water conservancy diversion lubrication groove on the retainer face of cylinder, plays cooling raceway and guide surface
Effect, improve the bearing limit speed of service.
3rd, the utility model makes the new application field of the adaptation of angular contact ball bearing, in high-speed aluminum foil rolling mill industry, superelevation
Press pump was promoted the use of already, obtained the universal favorable comment of user, and its applicability is very high, implementation easy to spread, had good economy
Benefit.
Brief description of the drawings：
Fig. 1 is the structural representation that cone ball guides retainer in existing angular contact ball bearing；
Fig. 2 is the structural representation that ball guides retainer in existing angular contact ball bearing；
Fig. 3 is the structural representation of interior guiding retainer in existing angular contact ball bearing；
Fig. 4 is the structural representation for guiding retainer in existing angular contact ball bearing outside single fulcrum；
Fig. 5 is the structural representation of new angular contact ball bearing.
Embodiment：
Embodiment：Referring to Fig. 1-Fig. 5, in figure, 01- outer rings, 02- inner rings, 04- rolling elements, 06- retainers, 07- outer rings
The face of cylinder, 08- retainers face of cylinder boss, 09- water conservancy diversion lubrication grooves.
New angular contact ball bearing includes outer ring 01, inner ring 02, rolling element 04 and retainer 06, wherein：Filled in outer ring 01
One outer ring face of cylinder 07 is set on the outer end internal diameter of ball cone, the centrifugal force of the retainer 06 rotated at a high speed with balance；Protecting
The external diameter for holding the non-stress side of frame 06 sets a retainer cylinder boss 08, retainer cylinder boss 08 and the outer ring face of cylinder 07 it
Between keep intrinsic guide clearance, to limit the movement locus of retainer 06, prevent retainer 06 from deviateing centre of gyration position.
The water conservancy diversion lubrication groove 09 of n axial direction is set on retainer face of cylinder boss 08, plays cooling raceway and guide surface
Effect, improve the bearing limit speed of service, n is greater than 1 natural number.
The utility model is designed reasonably, service life can be improved in the case where not increasing bearing cost, make angular contact ball axle
That holds adapts to new application field, and in high-speed aluminum foil rolling mill industry, super-pressure pump was promoted the use of already, and economic benefit and society imitate
It is beneficial obvious.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, every any simple modification made according to the technical essence of the utility model to above example, equivalent variations with
Modification, in the range of still falling within technical solutions of the utility model.
