Abstract

The invention relates to a device for detecting an axial clearance of a double-row tapered roller bearing. A base plate of an L-shaped support is provided with a U-shaped groove for a mandrel to pass through, a fixed seat is installed on the base plate, and an opening for the detected bearing to pass through is formed in the fixed seat. A baffle ring extending inwards is arranged on the fixed seat, and the outer ring of the detected bearing is arranged in the fixed seat. One end of the outer ring of the detected bearing is connected with the base plate, and the other end of the outer ring of the detected bearing is connected with the baffle ring on the fixed seat and is axially limited. The step-shaped mandrel is installed on the base plate through the detected bearing, a locking ring is connected to a threaded shaft of the mandrel in a screwed mode, and a shaft shoulder on the mandrel is connected with one end of the inner ring of the detected bearing and is axially limited. A meter frame is installed on a vertical plate of the L-shaped support, and a measurement meter is installed on the meter frame. The detecting end of the measurement meter is connected with the end face of the mandrel, and the center axis of the detection end coincides with the rotation central axis of the mandrel. The device for detecting the axial clearance of the double-row tapered roller bearing is simple in structure and convenient to operate, detection efficiency can be improved, and detection accuracy can also be improved.

Description

technical field

[0001] The invention relates to a detection device for the axial clearance of a double-row tapered roller bearing, which belongs to the technical field of double-row tapered roller bearing detection. Background technique

[0002] The application of double row tapered roller bearings requires relatively high load capacity and service life, and the axial clearance of double row tapered roller bearings has a great influence on the bearing rotation accuracy, load capacity and service life. Therefore, the control of double row tapered roller bearings The axial clearance of tapered roller bearings is very important.

[0003] At present, there are two methods for measuring the axial clearance of double-row tapered roller bearings. One is manual measurement. The operator first presses the end face of the outer ring of the bearing with his thumb, and then lifts the inner ring with the rest of his fingers to feel To determine, that is, the operator directly loads the ...
