Abstract
The present invention discloses a double-cone symmetrical conical roller and its application in conical roller bearing. Its roller is a doubel cone whose middle diameter is large and the diameter of its two ends is small, and its generating line is basically straight line, and is crossed with axial lead of rolling body, and two edges of two cut conical bodies are symmetrical so as to implement pure rolling, and can raise rotating speed of bearing, loading capacity and service life, and can reduce noise.
Description
The present invention relates to a kind of bipyramid symmetry circular cone rolling element and the application of this rolling element in tapered 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, be specially, on the retainer Internal and external cycle, increase oilhole etc., improve rotating speed and working life, reduce friction in order to reach, 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, and these methods are passive.
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 voice of bearing, and provide a kind of bipyramid symmetry circular cone rolling element and the application in tapered roller bearing thereof to society.
The real sight of available following mode the present invention:
Bipyramid symmetry circular cone rolling element is that the middle part diameter is big, and the bicone that the two ends diameter is little, its bus are straight line substantially, and intersect with the rolling element shaft axis, and the both sides of two truncated cone bodies are symmetrical.
