Radial clearance measurement and axial clearance elimination device for deep groove ball bearing

Abstract

The invention discloses a radial clearance measurement and axial clearance elimination device for a deep groove ball bearing, and the device comprises a case, a bearing clamping device is fixedly connected to the center of one side of the case, distance measurement sensors are fixedly connected to four sides of one side, equipped with the bearing clamping device, of the case, and a plurality of detection driving devices are arranged in an inner cavity of the case. Through grooves matched with the detection driving devices are formed in the side wall of the side, equipped with the bearing clamping device, of the case. The defect that a gap exists in positioning when the deep groove ball bearing automatically measures the radial clearance is overcome, and therefore the measuring precision and speed of the radial clearance of the bearing are improved.

Description

technical field [0001] The invention relates to the technical field of production of deep groove ball bearings, in particular to an axial backlash elimination device for radial clearance measurement of deep groove ball bearings. Background technique [0002] In order to reduce the noise generated when the bearing rotates and prolong the service life of the bearing, the bearing manufacturer controls the radial clearance of the bearing when assembling the deep groove ball bearing. In order to ensure this, most manufacturers will also conduct a full clearance inspection of the bearings to ensure quality, and the deep groove ball radial clearance machine is the main object of control, because when measuring the radial clearance, the general method is The inner diameter of the bearing is tightly matched for positioning, and the outer diameter is measured by hitting the outer diameter. If the fit is not tight, the measurement accuracy will be affected. However, if the bearing and ...

Problems solved by technology

In order to ensure this, most manufacturers will also carry out a full inspection of the bearing clearance to ensure quality, and the deep groove ball radial clearance machine is the main object of control, because when measuring the radial clearance, the general method is The inner diameter of the bearing is closely matched for positioning, and the outer diameter is measured. If the fit is not tight, the measurement accuracy will be affected. However, if the bearing and the positioning shaft are closely matched, it will be difficult for the bearing to enter the positioning shaft. This is to realize automation and batch production. Measure the most critical point
