Abstract
The invention relates to a shock proof cylinder roller bearing, comprising an outer ring, an inner ring, a retainer and a roller; wherein the retainer is arranged between the inner side of the inner diameter face of outer flange of the outer ring and the inner ring and is accurately guided by the outer diameter face of the side ring of the retainer, and the outer diameter face is opened with a plurality of circular oil grooves; the bottom of the flange side buses of the outer ring and the inner ring forms an included angle of 5-15 degrees with the end face of the bearing, and the roller path bus of the inner ring and the outer ring is opened with convexity of 0.005-0.020mm. The invention has the beneficial effects that: the retainer adopts an integral type entity retainer, structure is simple, stress state is clear, occupying space is smaller, maximum external force resistance can be obtained under the same quality condition, and the roller can be lengthened and increased to improve bearing capacity of the bearing; normal operation of roller can be ensured, lubricating condition of guiding face can be improved, friction consumption is reduced, working temperature rising is reduced, the bearing is prevented from metal friction when receiving thrust, and fatigue life of bearing is prolonged.
Description
Technical field
The present invention relates to a kind of roller bearing, relate in particular to a kind of shock proof roller bearing.
Background technique
Usually in operation process, rolling bearing can be subjected to impact force action, makes bearing parts produce motion through transmission between the bearing inner body and interaction, comprising displacement, speed, acceleration to reach transient equiliblium.This impact force not only makes load bearing element outer ring, inner ring and the roller of bearing be subjected to impulsive load, and makes the part retainer that does not stress substantially under the plateau be subjected to very big impact force.The example application of high impact loads is as the eccentric mass exciting unit of vibrating roller, eccentric shaft exciting unit, pile driver tup and the diesel unit etc. of vibrating sieve.The problem that the used bearing of existing this type of machinery occurs is mainly: retainer weares and teares, falls apart, ruptures, bearing temperature rise height, life-span weak point.
Summary of the invention
At above defective, the purpose of this invention is to provide a kind of all-in-one-piece shock proof roller bearing, by improvement, adapt to the application that higher rotation speed is followed high vibration and impact at the raceway of lasso and the special construction design of rib simultaneously to retainer, retainer guidance mode and guide surface.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of shock proof roller bearing, comprise by outer ring, inner ring, retainer and roller and forming, described retainer is arranged between the outer rib aperture surface inboard of outer ring and the inner ring and the outer diametric plane by the retainer side ring accurately guides, and offers some circular arc oil grooves on the described outer diametric plane; Described outer ring and inner ring rib side bus bottom and bearing face form 5 '-15 ' angle.The raceway bus of described inner ring and outer ring is offered the convexity of 0.005-0.020mm, and roller periphery bus is offered 0.005 to 0.020mm convexity; Described roller can be set to 14, and its diameter, length and outer ring raceway diameter can set gradually and be 37mm, 38mm, 230mm, and in addition, roller diameter, length and outer ring raceway diameter can set gradually and be 34mm, 34mm, 211mm.
The beneficial effect of shock proof roller bearing of the present invention is: its retainer adopts the integrated type solid cage, simple for structure, stress is distinct, the institute take up space less, can obtain the maximum external force ability of resisting under the equal in quality condition, having ready conditions simultaneously adds large roller to improve bearing load carrying capacity; Adopt the both sides rib of outer ring that retainer is accurately guided, make retainer under acceleration condition, still can keep correct position, guarantee normal operation of roller; On the retainer guide surface oil groove is set, helps lubricant oil and enter guide surface, thereby improve the lubrication state of guide surface, the consumption of reducing friction reduces the work temperature rise; The rib side becomes a little angle and is horn-like expansion with end face, can form hydrodynamic lubrication between rib side and roller end face, prevents to occur when bearing is subjected to thrust metal friction; Roller and raceway have convexity can prevent that spike stress appears in roller and raceway Line of contact two ends when being subjected to heavy load, thereby improves the fatigue life of bearing.
