Bearing ball installing groove detector

Abstract

Provided is a bearing ball installing groove detector. A fixed plate is installed on a base, a lead screw is installed in the middle of the fixed plate, one end of the lead screw is provided with a handle, a movable plate is installed on the surface of the fixed plate, a nut is fixed under the movable plate and is sleeved on the lead screw, and a positioning block is installed on the movable plate. A V-shaped chute is designed on the positioning block, a blocking plate is installed at one end of the chute, and the chute bottom of the chute and the axial direction of the lead screw are consistent. An included angle is in a range from 300 to 450, a fixed column is installed beside the positioning block, a dial indicator is installed on the fixed column, and a probe of the dial indicator right faces the groove bottom of a ball installing groove on a bearing excircle. When the bearing ball installing groove detector is used, an operator turns the excircle to ensure the probe to right face the lowest point of the installing groove and turns the handle on the lead screw, the excircle performs horizontal movement, the dial indicator measures a height numerical value of a protruding edge in the installing groove and a low point of a bearing arc-shaped groove, and the accuracy of a notching position of the installing groove can be detected.

Description

technical field [0001] The invention belongs to the technical field of bearing testing equipment, and relates to a bearing ball installation groove detector. Background technique [0002] The balls of the ball bearing are installed in the arc-shaped grooves of the inner ring and the outer ring, and the distance between the balls is fixed by a retainer installed in the gap between the inner and outer rings. When the balls are installed into the arc groove between the inner and outer rings, the extrusion installation method is commonly used. This method is to squeeze the outer ring with a pressure device to produce a slight deformation, and arrange the balls to the bottom of the arc groove in the outer ring. Then install the inner ring, align the arc grooves, cancel the pressure on the outer ring, the balls will be loaded into the arc grooves, and then install the retainer to fix the distance between the balls. For some bearings with wider outer ring and thicker wall thicknes...
