Abstract
The utility model discloses a circle -arc tooth slewing bearing, its profile of tooth is the circle -arc tooth, and it includes outer lane, rolling element, spacing block, sealing strip, inner circle and glib talker, outer lane and inner circle middle part constitute the raceway, rolling element and spacing block setting are sealed through the sealing strip between outer lane and inner circle in the raceway, division have the oilhole that is linked together with the raceway on the outer lane, the glib talker can according to the demand setting on outer lane or inner circle arbitrary face, outer lane terminal surface toothed portion shape is circular arc type flank profil. The utility model provides a circle -arc tooth slewing bearing, simple structure, convenient to use, mounting dimension and industry standard keep unanimous the time, and tooth portion has high contact fatigue intensity and flexural fatigue intensity, are about 2-5 times of involute gear intensity, and bearing capacity is big, have light in weight, characteristics such as overall dimension is little, the transmission is steady, load is high, low noise, have very big popularization and application and are worth.
Description
Technical field
The utility model relates to pivoting support field, particularly relates to the pivoting support of high strength.
Background technique
Current pivoting support driving gear is commonly involute cylindrical gear.Along with present pivoting support application is more and more wider, required operating mode is more and more numerous and diverse, also more and more higher to the requirement of the strength of gear teeth, precision.Existing involute cylindrical gear due to the radius of curvature of conjugate gears less, therefore contact strength is restricted, can not meet modern industry at a high speed, the development in high-power direction.In addition, the receptance of the manufacture of involute gear, installation, thermal distortion equal error is very large, and frictional power loss is larger.Teeth portion intensity is low, and gears meshing stationarity is poor, can not meet needs under specific operation.
Summary of the invention
The circle-arc tooth pivoting support that the utility model proposes, structure is simple, easy to use, while installation dimension and professional standard are consistent, teeth portion has high contact fatigue strength and bending fatigue strength, be about 2 ~ 5 times of involute gear intensity, bearing capacity is large, has the features such as lightweight, boundary dimension is little, stable drive, the high and low noise of load, has great application value.
For realizing above-mentioned technical purpose, the circle-arc tooth pivoting support that the utility model proposes, its profile of tooth is circle-arc tooth, it comprises outer ring, rolling element, spacing block, Stamping Steel Ribbon, inner ring and oil nozzle, raceway is formed in the middle part of described outer ring and inner ring, rolling element and spacing block are arranged in raceway, sealed by Stamping Steel Ribbon between outer ring and inner ring, outer ring has the oilhole be connected with raceway, oil nozzle can be arranged on outer ring or inner ring arbitrary face according to demand, and cycle surface tooth trace shape is circular arc type flank profil.
Described cycle surface tooth trace shape is single circular arc type flank profil.
Described cycle surface tooth trace shape is bicircular arcs type flank profil.
Described rolling element is steel ball or roller, and inner roller type is single-row ball type, double ball, bowling pin combination type or three organ timbering formulas.
