This utility model relates to the field of bearing runout torque detection technology, and more particularly to a composite bearing runout torque measuring fixture. A composite bearing runout torque measuring fixture includes: a mounting base, balance bars respectively disposed at both ends of the mounting base, a composite
flange bearing disposed between the two balance bars, and a detection component disposed at the end of one of the balance bars. The composite
flange bearing is disposed close to the mounting base, and the shaft hole of the mounting base, the outer
diameter of the balance bars, and the inner hole of the composite
flange bearing are coaxially arranged. This utility model provides a composite bearing runout torque measuring fixture with advantages such as accurate measurement results, small error, high
measurement precision, good stability and robustness, convenient
assembly and disassembly, and low cost.
