AI Technical Summary

Technical Problem

Existing cross roller bearing testing devices are complex in structure, occupy a large volume, have low testing efficiency, and require the bearings to be moved back and forth between different areas, which is time-consuming.

Method used

A test fixture comprising a base, a column, and a movable plate was designed. A servo motor drives the torque detection plate to rotate the outer ring of the crossed roller bearing at a constant speed. Combined with a torque sensor, the torque value required for rotation is directly read. The fixture has a simple structure, small footprint, and high flexibility of use.

Benefits of technology

It improves the testing efficiency of crossed roller bearings, offering convenience and high efficiency, simplifying the testing process, and reducing the space occupied by the equipment.

Abstract

This utility model discloses a testing fixture for crossed roller bearings, including a base, a column, and a movable plate. An inner expansion sleeve is fixedly mounted on the base, and a locking pressure head movably passes through the inner expansion sleeve. A servo motor is fixedly mounted on the movable plate, and the output shaft of the servo motor passes through the movable plate and is circumferentially fixedly connected to a torque detection plate. Several sets of locating pins are circumferentially distributed at the bottom of the torque detection plate. The inner expansion sleeve is circumferentially fixedly connected to the inner ring of the crossed roller bearing, and the torque detection plate is circumferentially fixedly connected to the outer ring of the crossed roller bearing via the locating pins. A torque sensor is installed inside the torque detection plate. This testing fixture for crossed roller bearings has the advantages of simple structure, small footprint, high flexibility, and ease of use, and can effectively improve testing efficiency.
