Abstract

The invention relates to a convenient-to-disassemble end supporting mechanism for a motor test system. The convenient-to-disassemble end supporting mechanism for the motor test system mainly comprises a supporting block and a pressing block, and is simple in structure, convenient to disassemble and assemble and high in repeated test precision. The supporting block can be installed by calibrating the coaxiality of the supporting block and each component of the system at one time through a coaxiality calibrator. The pressing block limits the tail end of a motor shaft in the radial direction and the circumferential direction only through fastening screws, repeated disassembly is very convenient, and the repeated testing precision of a tested system cannot be affected. According to the method, a coaxiality calibrator does not need to be used for repeatedly calibrating and detecting the coaxiality of a to-be-tested motor and each part of the test system, so that the requirement on the operation technical level of test personnel is greatly reduced, and the test working efficiency can be greatly improved. In addition, the high-precision test requirement for repeated disassembly of motors of different specifications under the same output shaft diameter can be met.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a detachable end support mechanism for a motor testing system. Background technique [0002] The installation accuracy of the motor under test is crucial to the accuracy of its performance test, especially in high-precision test occasions that require repeated disassembly of the motor. There are various forms of existing high-precision motor test systems, but there is little research on high-precision test systems that require frequent replacement of the motor under test, or the cost is relatively high. At present, in order to ensure the test accuracy, the general test system needs to use a coaxiality calibrator to re-test the concentricity of the axis of each device after replacing the parts, which is very time-consuming, and it is difficult to ensure that the axes of each device in the system are coaxial after each replacement of the motor degree of consistency.
