Abstract
The present invention discloses a kind of four-point rolling bearing with unequal contact angles, the rotary middle point K of roll left (3) point of contact A and right raceway (9) point of contact B and rolling element (6) on the inner ring (1) forms two wrapping angle B1, the rotary middle point K of roll left (4) point of contact D and right raceway (10) point of contact C and rolling element (6) on two outer rings (2) forms two wrapping angle B2, two two wrapping angle B1 and B2 are unequal, B1 is 40 degree～90 degree when inner ring (1) is activity, and B2 is that 90 degree～160 are spent; When inner ring (1) B1 for fixedly the time is 90 degree～160 degree, B2 is that 40 degree～90 are spent; And two two wrapping angle B1 on inner ring (1) and the two outer rings (2) and the differential seat angle of B2 are 20 degree～140 degree.Because two two wrapping angle B1 and B2 are unequal, then can guarantee to reduce the rotating speed of retainer, and reduce or increase the rotating speed of bearing thus, and can not change the centrifugal force that acts on the rolling element, greatly reduce the degree of wear of bearing, prolong the working life of bearing.
Description
Technical field:
The present invention relates to a kind of rolling bearing, especially a kind of four-point rolling bearing with unequal contact angles.
Background technique:
The present two wrapping angle four-point rolling bearings that use, all be that two two wrapping angles equate mostly, though the impact resistance of rolling bearing and the reliability of transmission have been had certain improvement, but because of its angle value little, and angular range is narrow, centrifugal force is not significantly reduced, particularly under the condition of running up, it is that rolling element is done periodically light contact with a raceway that does not load that point of contact makes, also may cause the damage of raceway or rolling element, and produce the additional force act on the retainer frictional force is strengthened, cause the damage of bearings degree to be accelerated.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, providing a kind of can reduce friction, and prolongs the bearing four-point rolling bearing with unequal contact angles in working life.
Technical solution of the present invention is: a kind of four-point rolling bearing with unequal contact angles, be provided with inner ring, two outer rings, between inner ring and two outer ring, retainer is set, rolling element is set in retainer, on inner ring, be provided with symmetrically and roll left and right raceway, on two outer rings, be provided with symmetrically and roll left and right raceway, rolling left on the inner ring, rolling left on right raceway and the two outer ring, the whole raceway that right raceway forms constitutes 4 contact raceways that roll of rolling element, the rotary middle point K of roll left point of contact A and right raceway point of contact B and rolling element on the inner ring forms two wrapping angle B1, the rotary middle point K of roll left point of contact D and right raceway point of contact C and rolling element on two outer rings forms two wrapping angle B2, two two wrapping angle B1 and B2 are unequal, B1 is 40 degree～90 degree when inner ring is activity, and B2 is that 90 degree～160 are spent; When inner ring B1 for fixedly the time is 90 degree～160 degree, B2 is that 40 degree～90 are spent; And two two wrapping angle B1 on inner ring and the two outer ring and the differential seat angle of B2 are 20 degree～140 degree.
Roll left and right raceway between inner ring on be provided with a through hole at least, roll left and right raceway between two outer rings on be provided with a through hole at least, to guarantee effectively lubricant oil to be guided into rolling element and raceway position contacting and rolling element and retainer position contacting, also unnecessary lubricant oil can be derived.
The invention has the beneficial effects as follows because two two wrapping angle B1 and B2 are unequal, then can guarantee to reduce the rotating speed of retainer, and reduce or increase the rotating speed of bearing thus, and can not change the centrifugal force that acts on the rolling element, greatly reduce the degree of wear of bearing, prolong the working life of bearing.

Embodiment:
A kind of four-point rolling bearing with unequal contact angles, be provided with inner ring 1, two outer rings 2, between inner ring 1 and two outer ring 2, retainer 5 is set, rolling element 6 is set in retainer 5, on inner ring 1, be provided with symmetrically and roll left 3 and right raceway 9, on two outer rings 2, be provided with symmetrically and roll left 4 and right raceway 10, roll left 3 on the inner ring 1, roll left 4 on right raceway 9 and the two outer rings 2, the whole raceway that right raceway 10 forms constitutes 4 contact raceways that roll of rolling element 6, it is characterized in that: the rotary middle point K of roll left 3 point of contact A and right raceway 9 point of contact B and rolling element 6 on the inner ring 1 forms two wrapping angle B1, the rotary middle point K of roll left 4 point of contact D and right raceway 10 point of contact C and rolling element 6 on two outer rings 2 forms two wrapping angle B2, two two wrapping angle B1 and B2 are unequal, B1 is 40 degree～90 degree when inner ring 1 is activity, and B2 is that 90 degree～160 are spent; B1 for fixedly the time is 90 degree～160 degree when inner ring 1, and B2 is that 40 degree～90 are spent; And two two wrapping angle B1 on inner ring 1 and the two outer rings 2 and the differential seat angle of B2 are 20 degree～140 degree.Roll left 3 and right raceway 9 between inner ring 1 be provided with a through hole 7, roll left 4 and right raceway 10 between two outer rings 2 be provided with a through hole 8.
When inner ring 1 is activity, rolling left on two outer rings 24 contacts with rolling element 6 on 2 of C, D with right raceway 10, it is 160 degree that 2 of C, D become B2 with the rotary middle point K layout of rolling element 6, rolling left on the inner ring 13 contacts with rolling element 6 on 2 of A, B with right raceway 9,2 of A, B become B1 with the rotary middle point K layout of rolling element 6 be 40 when spending, the rotational speed of retainer reduces by 80%, and the rotational speed of inner ring 1 improves 1.5 times, and the centrifugal force that acts on the rolling element 6 is identical.
