Single-Row Crossed Rollers Slewing bearings

CHARACTERISTIC OF STRUCTURE PERFORMANCEAND APPLICATION
The single-row cross roller slewing ring is composed of two seatrings. It features compact in design, light

in weight, high precision and small fitting clearance.As the rollers are 1:1 cross arrange, it is suitable

for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force. slewing bearing, slewing bearings .The single-row crossed roller slewing rings are widely used for histing, transporting, engineering machines as well as for military products.

  Notes:
  1. n1-number of lubricating holes, evenly distributed, lubricating nipple M10????GB1152-1153-79.
  2. mounting hole maybe replaced with screw hole, tooth width maybe taken as H-h.
  3. Gear force of beriphery given in the table is its maximum value, nominal force of periphery is taken 1/2 of the given calue. slewing bearing, slewing bearings
  4. the trim top coeffivient of inner tooth is 0.1and 0.2,respectively

Gear heat treatment forms( Single-Row Crossed Rollers Slewing bearings )
Due to the need of transmission power or torque of slewing bearing, there are usually teeth in a ferrule. The general state of heat treatment of gear is normalizing or tempering. And the tooth surface and tooth root is IF Quenching
