Abstract
The invention discloses a retainer of a spherical thrust roller bearing for a rolling mill; a tapered ring is arranged at one side of the retainer, inclined teeth are uniformly distributed at the other side of the retainer, and teeth are embedded on the tapered ring, spaces for containing cylindrical rollers are formed among the teeth, the teeth are uniformly distributed and arrayed on a circular ring; the outer diameter surface and the inner diameter surface of the tooth are consistent to the outer diameter surface and the inner diameter surface of the tapered ring, and two inner end surfaces of the teeth are planes; two sides of the outer end surface of each tooth are rounded off; the retainer of the spherical thrust roller bearing for the rolling mill has the advantages of compact structure, perfect sealing, convenient assembly and disassembly, and large automatic aligning amplitude, so as to improve the working condition and greatly improve the bearing life.
Description
Technical field
The present invention relates to a kind of retainer of spherical thrust roller bearing for rolling mill, belong to the thrust-bearing technical field.
Background technique
Self-aligning thrust roller bearing is owing to have advantages such as compact structure, perfect, the easy to loading and unloading and self-aligning amplitude of sealing are bigger, its feature is: being used to bear thrust load is main axial and united load, but radial load must not surpass thrust load 55%.Compare with other thrust-bearings, this kind pivot friction factor is lower, and rotating speed is higher, and has aligning performance.The listed thrust force aligning bearing of the present invention is the reinforced bearing through optimal design.The roller of this kind bearing is asymmetric spherical roller, can reduce roller and raceway slide relative at work, and roller is long, diameter is big, and roller quantity is many, and the load bearing capacity height adopts oil lubrication usually, and indivedual low speed situations can be used lubricating grease.
Thrust roller bearing adopts steel or copper production solid cage; Because the seat ring raceway is a concave sphere, allow axle certain tilt angle to be arranged with housing axis.The on-stream rolling element of thrust roller bearing is subjected to centrifugal force to refuse effect, and slide relative between rolling element and the raceway causes blowout patche to separate with seat ring, for guaranteeing the bearing proper functioning, must apply certain thrust load.Retainer plays guiding and isolates the effect of roller, bearing roller in the running rolls on the raceway of Internal and external cycle, the running of roller driving bearing retainer is again rotated, thereby cause roller and retainer to produce friction, when the bearing rotating speed is higher, can produce bigger friction owing to action of centrifugal force, thereby reduce the transmission efficiency and the life-span of bearing, compare the effect that conical bearing has significant raising bearing capacity with ball bearing, but its low transmission efficiency is again its outstanding shortcoming.
Summary of the invention
The present invention provides a kind of retainer of spherical thrust roller bearing for rolling mill for solving on the above technical problem, has solved problems such as assembling difficulty.
The retainer of a kind of spherical thrust roller bearing for rolling mill of the present invention is characterized in that: described retainer one side is the circular cone ring, the teeth that the opposite side of retainer is distributing uniformly and, and teeth are embedded on the circular cone ring; Constituted the space that can hold cylindrical roller between the teeth, teeth are arranged on the annulus in equally distributed mode; The outer diametric plane of described teeth and inner hole surface are consistent with the outer diametric plane and the inner hole surface of circular cone ring, and two interior edge faces of teeth are the plane; Both sides, the exterior edge face rounding of described each teeth.
A kind of spherical thrust roller bearing for rolling mill involved in the present invention comprises outer ring, inner ring, roller, retainer and inner ring lining; Retainer is the circular cone annular, and the upside of retainer has trapezoidal teeth, and the space between the teeth can hold roller.Inner ring is the inverted cone annular, and there is a roller raceway in the outside; The outside rounding of outside top; The inner ring outside top has an outstanding annulus, and the downward vertically circular cone bulge loop of a direction is arranged on the annulus; One arc groove is arranged between circular cone bulge loop and the conical surface; There is shoulder hole the inner ring inboard, between last ladder surface and the downstairs face conical grooves is arranged, and the both sides rounding of shoulder hole, the fillet of upside are greater than the fillet of bottom side.After the inner ring lining of thrust roller bearing is contained on the inner ring, by punching press the inner ring lining being fixed on the inner ring, thereby having guaranteed being fastenedly connected of inner ring lining and inner ring, is the work that bearing can be stable.
The retainer of self-aligning thrust roller bearing of the present invention has advantages such as compact structure, perfect, the easy to loading and unloading and self-aligning amplitude of sealing are bigger, thereby has improved operating conditions, improved bearing life greatly.

Fig. 2 is the sectional structure chart of bearing of the present invention.
Embodiment
The present invention is as seen from Figure 1, Figure 2: bearing comprises outer ring 1, inner ring 2, roller 3, retainer 4 and inner ring lining 5; Retainer 4 is the circular cone annular, and the upside of retainer 4 has trapezoidal teeth, and the space between the teeth can hold roller 3.Retainer one side is the circular cone ring, the teeth that the opposite side of retainer is distributing uniformly and, and teeth are embedded on the circular cone ring; Constituted the space that can hold cylindrical roller between the teeth, teeth are arranged on the annulus in equally distributed mode; The outer diametric plane of teeth and inner hole surface are consistent with the outer diametric plane and the inner hole surface of circular cone ring, and two interior edge faces of teeth are the plane; Both sides, the exterior edge face rounding of each teeth.Inner ring 2 is the inverted cone annular, and there is a roller raceway in the outside; The outside rounding of outside top; Inner ring 2 outside top have an outstanding annulus, and the downward vertically circular cone bulge loop of a direction is arranged on the annulus; One arc groove is arranged between circular cone bulge loop and the conical surface; There is shoulder hole inner ring 2 inboards, between last ladder surface and the downstairs face conical grooves are arranged, and the both sides rounding of shoulder hole, the fillet of upside are greater than the fillet of bottom side.
A kind of preferred implementation: the self-aligning thrust roller bearing that with the nominal outside diameter is 360mm is an example, and the nominal outside diameter of retainer annulus is 351mm, and the nominal outside diameter of retainer annulus is 327mm, and the circular cone tilt angle is 44 °.
