Abstract
The utility model discloses a double-row internal-regulation bearing, which particularly relates to a double-row internal-regulation bearing with high load and high rotation speed performances. The double-row internal-regulation bearing comprises an inner circle and an outer circle, and a retainer is arranged between the inner circle and the outer circle. The retainer is a single-piece entity retainer whose both ends are evenly distributed with pocket holes, and the pocket holes on both sides are arranged in crossing. A rolling body is arranged in each pocket hole. The utility model is characterized in that the rolling body comprises a spherical roller and a steel ball, wherein the spherical roller and the steel ball are alternatively arranged along the circumferential direction of the retainer. The double-row internal-regulation bearing can not only be used in the occasion with higher rotation speed requirements, but also can be used in the occasion with higher loading requirements, and the application scope is not limited.
Description
Technical field
The utility model relates to a kind of bearing.Specifically, be double-row self-aligning bearing with high loading, high rate performance.
Background technique
Know all that at machine industry the various double-row self-aligning bearings that mechanically use mainly contain two kinds on double-row self-aligning roller bearing and double-row self-aligning ball bearing.These two kinds of bearings are formed by retainer between inner ring, outer ring, the Internal and external cycle and the rolling element that is installed in the retainer pocket hole.Wherein, the rolling element of double-row self-aligning roller bearing is a spherical roller, and the rolling element of double-row self-aligning ball bearing is a steel ball.Because the rolling element of double-row self-aligning roller bearing is a spherical roller, contacting between spherical roller and Internal and external cycle is the line contact, and area of contact is bigger, and area of contact one is big, and load is just big.But surface of contact one is big, and frictional force is just big, and therefore, the limit speed of this bearing is lower, can not be used in the occasion that rotating speed is had relatively high expectations, and Applicable scope is restricted.And the rolling element of double-row self-aligning ball bearing is a steel ball, and the surface of contact between steel ball and Internal and external cycle contact for point, and area of contact is less, and surface of contact one is little, and frictional force is just little, so the limit speed of this bearing is higher.But the surface of contact one between steel ball and Internal and external cycle is little, and the load that can bear is just little, and therefore, this bearing can not be used in load and require bigger occasion, and Applicable scope also is restricted.
The model utility content
Problem to be solved in the utility model provides a kind of double-row self-aligning bearing.This double-row self-aligning bearing can be used in the occasion that rotating speed is had relatively high expectations, and can be used in load again and require bigger occasion, and Applicable scope is unrestricted.
For addressing the above problem, take following technological scheme:
Double-row self-aligning bearing of the present utility model contains inner ring and outer ring, between inner ring and outer ring retainer is arranged.This retainer is the monolithic entities retainer, and its both sides are evenly equipped with the pocket hole, and cross-shaped layout between the pocket hole of both sides.In each pocket hole rolling element is arranged all, be characterized in that described rolling element contains spherical roller and steel ball, this spherical roller and steel ball are alternately shape layout along the circumferencial direction of retainer.
On the cylindrical of outer ring, be processed with circumferential recess, be processed with oilhole in the circumferential recess.
Take such scheme, have the following advantages:
Because its rolling element of double-row self-aligning bearing of the present utility model contains spherical roller and steel ball, this spherical roller and steel ball are alternately shape layout along the circumferencial direction of retainer, adopt the some contact to contact the tribology principle that combines, not only improved the limit speed of bearing, also improved load with line.Make the utility model can not only be used in the occasion of having relatively high expectations, can be used in load again and require bigger occasion that Applicable scope is unrestricted at rotating speed.
Description of drawings
Accompanying drawing is a double-row self-aligning bearing structure schematic representation of the present utility model.
Embodiment
As shown in drawings, double-row self-aligning bearing of the present utility model contains inner ring 6 and outer ring 2, and 2 of inner ring 6 and outer rings are equipped with retainer 4.Retainer 4 wherein is the monolithic entities retainer, and its both sides are evenly equipped with the pocket hole, and cross-shaped layout between the pocket hole of both sides.In each pocket hole rolling element is installed all.Rolling element wherein contains spherical roller 5 and steel ball 1, this spherical roller and steel ball are alternately shape along the circumferencial direction of retainer 4 to be arranged, promptly arranges according to the sequence alternate shape of a spherical roller 2, steel ball 1, spherical roller 2, a steel ball 1.......Adopt the some contact to contact the tribology principle that combines, not only improved the limit speed of bearing, also improved load with line.
For ease of in bearing, adding lubricant oil, on the cylindrical of outer ring (2), be processed with circumferential recess, be processed with the oilhole 3 that is used for refueling in the circumferential recess.
Claims (2)
1. the double-row self-aligning bearing comprises inner ring (6) and outer ring (2), between inner ring (6) and outer ring (2) retainer (4) is arranged; This retainer is the monolithic entities retainer, and its both sides are evenly equipped with the pocket hole, and cross-shaped layout between the pocket hole of both sides; In each pocket hole rolling element is arranged all, it is characterized in that described rolling element contains spherical roller (5) and steel ball (1), this spherical roller and steel ball are alternately shape layout along the circumferencial direction of retainer (4).
2. double-row self-aligning bearing according to claim 1 is characterized in that on the cylindrical of outer ring (2) circumferential recess being arranged, and oilhole (3) is arranged in the circumferential recess.
