Abstract
A cylindrical roller with symmetrical two conic ends and its application to the bearing are disclosed. It features that it has a cylindrical central part with big diameter and two truncated cones at two ends, and its generatrix is basically a straight line and is crossed with the axial line of roller, so realizing pure rolling in bearing. Its advantages are no slide friction and collision, high speed and load power, low noise and long service life.
Description
The present invention the present invention relates to a kind of bipyramid symmetry cylinder rolling element and the application of this rolling element in roller bearing.
Existing bearing all is by cone, cylindrical body and spherical surface body (convexity), and these three kinds of rolling elements are formed the seriation roller bearing, as tapered roller bearing and roller bearing etc.And in existing bearing, these three kinds of rolling elements axially come limiting displacement and axial clearance with end face, the inside and outside raceway of bearing must be worn a grade limit, is not the outer raceway of inner ring, be exactly the outer ring in raceway make a grade limit, perhaps the centre adds guide collar.In a word, existing roller bearing be unable to do without shelves limit and guide collar, and rolling element could axially have a grade margin position along specific rolling surface in raceway like this, radially has under the condition of inside and outside raceway surface of contact restriction, makes rotation and revolution motion, transmitted load.When rolling element rolls along the shelves limit in raceway like this, both ends of the surface certainly lead to sliding friction and gnaw and cut phenomenon, are difficult to reach pure rolling, and when load increases, stress also can occur and concentrate on rolling element one end, make the rolling element part impaired, thereby cause rolling element in rotation and revolution motion, the deflection shaft axis, cause stressed energy imbalance, limited rev limit, working life the limit, the limit of the load capacity limit and noise.People are in order to address the above problem, adopted a lot of methods and technical measures so that reach technical requirements, the common method that adopts: one, improve the bearing accuracy of manufacturing, strict limit shape deviation and surface finishment have especially also been made various lathes, in order to improve the geometric accuracy on raceway shelves limit, and also descended very big time at the rolling element two ends, make circular arc as roller both ends of the surface arris, heart portion is recessed to wait measure, but does not have positive effect.Two, the means that generally adopt so far both at home and abroad are to improve lubricating condition, are specially, and increase oilhole etc. on the retainer Internal and external cycle, to improve rotating speed and working life in order reaching, to reduce friction, increase the constantly oiling of transmission load, make bearing race form oil film, make bearing obtain sufficient lubrication.Yet, these measures fundamentally do not solve the existing problem of roller bearing, these methods are passive, also have, people wish that the contact of cylinder rolling element in raceway should radially evenly distribute, so successively invented spherial rolling body and convex surface rolling element, also be in order to eliminate the purpose that load of rolling body stress concentrates on the edge, yet best convex shape depends on the direction and the size of service load, and is just inapplicable to another kind of state according to the determined desirable protuberance shape of the load condition of a certain characteristics, so, can there be a kind of rolling element both can reach the contact stress balance, can eliminates the edge load effect again, can bear radial load, can bear the section axial load again, can also remove the limit of losing rank, realize pure rolling, become people's expectation.
Purpose of the present invention just is, for realizing that the motion of rolling element in raceway is pure rolling, thereby improve rotating speed, working life, load capacity and the reduction noise of bearing, reach the contact stress balance, can eliminate the edge load effect again, can bear radial load, can bear the section axial load again, and provide a kind of bipyramid symmetry cylinder rolling element and the application in roller bearing thereof to society.
Available following mode realizes the present invention:
Bipyramid symmetry cylinder rolling element, its rolling element is based on mediate cylindrical, and two ends truncated cone body is symmetrical, double cone body and cylindrical body are on same shaft axis, its outer surface bus is continuous straight line substantially, and cylinder diameter is the benchmark nominal size of rolling element, and the biconvex cone angle intersects at shaft axis.
Described rolling element length is called the short cylindrical rolling element within 1.2 times of rolling element diameter.
Described rolling element length is more than 2 times of rolling element diameter, is called the long cylinder rolling element.
Bipyramid symmetry cylinder rolling element and the application in roller bearing thereof, the feature of the rolling element of this series bearing is the convex cone cylindrical body, its outer surface intermediate cylindrical is big, the two terminal circle conical surface is little, and it is crossing with the rolling element shaft axis, by rolling element middle part perpendicular to the plane of its shaft axis in two ends bipyramid face be symmetrical, this roller bearing has changed the drawback that straight roller bearing can only bear radial load, based on the carrying radial load, and bear section axial and load, bipyramid symmetry cylinder rolling element and bearing race location are not by shelves limit, end face right angle, but by symmetrical conical surface shelves limit, be axially locating, radial location is by the middle circle cylinder, and raceway concave cone symmetry plane promptly is that grade limit is again a raceway, thereby eliminate rolling element edge stress concentration phenomenon, two ends bipyramid symmetric figure control rolling element departs from bearing axis in raceway, rolling element contacts outer surface bipyramid concave face and increased than common roller straight line with raceway, so bearing capacity increases.This rolling element has been realized pure rolling in raceway, can in various roller bearings, use, as single, double row or multiple row bipyramid symmetry roller bearing, be divided into unidirectional bipyramid symmetry cylinder centripetal thrust force roller bearing and two-way bipyramid symmetry cylinder centripetal thrust force roller bearing and medium-sized unidirectional bipyramid symmetry cylindrical thrust roller bearing and two-way bipyramid symmetry cylindrical thrust roller bearing etc. by bearing capacity and thrust direction.
