Problems solved by technology

The demand for double-row tapered roller bearings continues to increase. The existing double-row tapered roller bearing outer ring double raceway measurement, the traditional raceway size inspection tool uses two raceway sample rings to measure the outer ring raceway size deviation , the two ends of the outer ring are the measurement benchmarks, which leads to the inconsistency between the measurement benchmark and the processing benchmark of one side of the raceway, and due to the dispersion of the end face width of the outer ring, there is an error in the raceway measurement, which causes the operator to repeatedly debug the equipment during the processing , and the size of the raceway affects the final fit, affects production efficiency, increases the difficulty of final assembly fit, and reduces the fit rate

Embodiment Construction

[0011] Embodiment is illustrated below in conjunction with accompanying drawing:

[0012] There are two D712 bearing detectors 6 on the measurement base 1, one of which passes through the pillar 5 and its measuring point 3 corresponds to the raceway A2 of the bearing, and the other bearing detector 6 passes through the pillar 5 and its measuring point (3 ) corresponds to the raceway B2 of the bearing

[0013] The measurement standard of the present invention is a measurement standard, and the side of the outer ring with a flange is used as the reference end face. At the same time, the processing standard and the detection standard are guaranteed to be unified. Two D712 bearing testers 6 are used to measure the raceway A2 and the rolling track respectively with one standard. Road B4 eliminates the measurement reference error, eliminates the phenomenon of misjudgment between processes, greatly improves the efficiency of assembly matching and the accuracy of clearance, and improv...

Abstract

The invention provides a double-row tapered roller bearing outer ring double-raceway integrated sample ring. The sample ring is characterized in that two bearing detectors are arranged on a measuringbase surface, a measuring point of one bearing detector corresponds to a raceway A of a bearing through a support column, and a measuring point of the other bearing detector corresponds to a raceway Bof the bearing through a support column. The sample ring has advantages of guaranteeing unification of the machining reference and the detection reference, eliminating an error of the measurement reference, eliminating a misjudgment phenomenon between the processes, greatly improving matching sleeve assembling efficiency and clearance accuracy, improving production efficiency and the like.

Description

[0001] technical field [0002] The invention relates to a tool for detecting the raceway size of the outer ring of a double-row tapered roller bearing, in particular to a double-row tapered roller bearing outer ring integral sample ring with double raceways. Background technique [0003] With the continuous development of the automobile industry and the continuous improvement of the technical level of automobile bearings, double-row tapered roller bearings have gradually replaced traditional single-row tapered roller bearings. The demand for double-row tapered roller bearings continues to increase. The existing double-row tapered roller bearing outer ring double raceway measurement, the traditional raceway size inspection tool uses two raceway sample rings to measure the outer ring raceway size deviation , the two ends of the outer ring are the measurement benchmarks, which leads to the inconsistency between the measurement benchmark and the processing benchmark of one side o...
