The manufacture of retainer design scheme.There are problems for bearings: 1, selecting the bearing revolving speed of ribbon retainer is too low to be unable to satisfy
Racing motorcycle crankcase operating condition, causes bearing fatigue to damage, thus service life requirement is not achieved.2, it is kept using nylon
The resistance to temperature of frame bearing is inadequate, causes phenomenon that bearing life is short and its universal, 3, bearing working performance be unable to satisfy motor match
The condition of vehicle crankshaft high-speed operation.
Summary of the invention
The present invention its be intended to provide the bearing that a kind of performance is able to satisfy racing motorcycle crankshaft high-speed operating condition.
In order to solve the above technical problems, the object of the present invention is achieved like this:
A kind of high-speed bearing for racing motorcycle crankcase is 0 class bearing structure, including outer ring, inner ring, rolling
Body, retainer, for the rolling element between outer ring, inner ring and retainer, the retainer is symmetrical double-disk structure
And two panels fixing assembling, material are phenolic resin；
The retainer uses interior guidance mode；
The outer ring rolls 0.515-0.525 times of its ditch curvature of bulk channel for rolling element diameter, the rolling of the inner ring
Its ditch curvature of kinetoplast channel is 0.535-0.54 times of rolling element diameter, and the outer ring, the rolling element groove of inner ring its ditch song
Rate is plus tolerance.
Preferred embodiment on the basis of above scheme and as above scheme: the retainer is carried out using closing-up
Fixing assembling.
Preferred embodiment on the basis of above scheme and as above scheme: the numberical range of the plus tolerance is
0.01-0.1。
Preferred embodiment on the basis of above scheme and as above scheme: to the high-speed bearing of racing motorcycle crankcase
It is quenched, the quenching technical comprises the steps of S1: primary quenching is carried out to blank；
S2: it is once tempered after quenching；
S3: freezing processing is carried out after tempering；
S4: the blank after freezing carries out thick grinding；
S5: a stable tempering is carried out after corase grinding；
S6: fine grinding is carried out after stable tempering；
S7: Quadratic Stability tempering is carried out；
S8: it is ground eventually after Quadratic Stability tempering；
S9: finished product is obtained.
Preferred embodiment on the basis of above scheme and as above scheme: the cryogenic temperature of the step S3 is -70
℃-90℃。
The present invention is prominent and beneficial compared with prior art to have the technical effect that 1, using biplate phenolic resin retainer iron
The integral mode of closing-up, solves bearing assembly problem in this way；2, interior guidance mode is easier to realize that the height of bearing turns
Fast performance also solves the problems, such as bearing heatproof simultaneously；3, using new high speed curvature design scheme, to improve turning for bearing
Speed makes bearing preferably adapt to the high revolving speed operation of crankshaft.

Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the attached drawing in embodiment, to reality
The technical solution applied in example is clearly and completely described.
A kind of high-speed bearing for racing motorcycle crankcase is 0 class bearing structure, including outer ring 1, inner ring 2, rolling
Body 3, retainer 4, rolling element 3 are located between outer ring 1, inner ring 2 and retainer 4, and retainer 4 includes the first retainer 41 and the
Two retainers 42, the first retainer 41 and the second retainer 42 are symmetrical double-disk structure, and the first retainer 41 and second is protected
42 fixing assembling of frame is held, material is phenolic resin, and the retainer of such structure has high temperature resistant, light-weight and holding frame material
In oil-containing itself the advantages that, the greasy property of rolling element is more preferable, can preferably adapt to high-revolving operating condition.
The retainer 4 uses interior guidance mode；It should be noted that the internal diameter of retainer 4 is small just apart from 2 gap of inner ring
Interior guidance is cried, the inner ring of the application is swivel ferrule, and provides rolling element when rotated with drawing torque, if bearing load is not
When stable or load is light, it may appear that skid；And retainer uses interior guidance, then forms oil film in the guide surface of retainer, by
In oil film friction in non-loading zone inner ring to retainer with drawing force to increasing retainer to the additional drives of rolling element
Torque, and can prevent rolling element from skidding, it is easier to it realizes the high rate performance of bearing while also solving the problems, such as bearing heatproof.
Further, in the present embodiment, the Internal and external cycle combination angular contact ball bearing high speed curvature design scheme of bearing is improved
The revolving speed of bearing；Specifically, its ditch curvature " outside R " of the rolling bulk channel 11 of outer ring 1 is the 0.515-0.525 of rolling element diameter
Times, its ditch curvature " in R " of the rolling bulk channel 21 of inner ring 2 is 0.535-0.54 times of rolling element diameter, and outer ring 1, inner ring 2
Its ditch curvature of rolling element groove 11/21 is plus tolerance.
Preferably, the numberical range of plus tolerance is 0.01-0.1, using the further improvement bearing of the design of plus tolerance
Resistance to high rate performance.
By the way of closing-up assembly, phenol is fixed in first retainer 41 and the second retainer 42 by retainer 4
The urea formaldehyde retainer incorporated mode of iron rivet riveting, solves bearing assembly problem in this way.
Outer ring 1 and inner ring 2 are handled using P4 grades of precision bearing quenching technicals.
Specifically, quenching technical comprises the steps of S1: carrying out primary quenching to blank；
S2: it is once tempered after quenching；
S3: freezing processing is carried out after tempering；
S4: the blank after freezing carries out thick grinding；
S5: a stable tempering is carried out after corase grinding；
S6: fine grinding is carried out after stable tempering；
S7: Quadratic Stability tempering is carried out；
S8: it is ground eventually after Quadratic Stability tempering；
S9: finished product is obtained.
Preferably, the cryogenic temperature of step S3 is -70 DEG C -90 DEG C.
By above-mentioned quenching, freezing processing, the technique of stable tempering stablizes bearing internal external circle interior tissue twice
Processing is to realize bearing long life requirement.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore: it is all according to
The equivalence changes that structure of the invention, shape, principle are done, should all be covered by within protection scope of the present invention.
