DEVICE FOR MEASUREMENT OF RADIAL CLEARANCE IN ROLLER BEARING

摘要

FIELD: machine building.;SUBSTANCE: device comprises a base with a rack, installed perpendicularly on it, in which the slots are made. The lower slot is designed with a possibility of mounting and movement in it of a rod, in which an additional rod with the measuring indicator is installed. In the upper slot with tightness a calibration disk is installed, on the front surface of which in a step manner radial belts are made. In the calibration disk centre a threaded hole is made for a bolt fixing the bearing on the calibration disk through a clamp bar, on one of the surfaces of which in a step manner radial belts are made, by the sizes corresponding to radial belts, designed on the calibration disk. Also the device comprises a belt with a weight, laid on a bearing cup. Belt branches are supported by rollers installed on edges of the rack between the lower part of the lower slot and the base.;EFFECT: expansion of an arsenal of tools allowing to measure a radial clearance in bearings of various dimension groups.;2 dwg
