Torque measurement test bed and torque measurement method thereof

Abstract

The invention discloses a torque measurement test bed, which comprises an axial loading device, a bearing part, a torque detection device and a disk drive device. The axial loading device comprises aloading portal frame and a loading oil cylinder fixed on the loading portal frame; the bearing part comprises a T-shaped platform and a bearing bracket arranged on the T-shaped platform; the torque detection device comprises a main shaft fixed on the bearing bracket; the main shaft is provided with a torque tested piece; a pressure sensor is arranged at one end of the main shaft, close to the torque tested piece; a torque sensor is arranged at the other end of the main shaft; the torque tested piece is placed in an oil tank; the oil tank is supported on the bearing bracket through a supportingframe; the disk drive comprises a coupling. Compared with the prior art, a torque coefficient measuring test bed of the torque measuring test bed is used for measuring the torque coefficient of a vertical sliding bearing thrust pad at the moment of starting, has certain universality, and can adjust the specific pressure, oil temperature and the like according to different working conditions of the vertical sliding bearing of different types.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to a torque measurement test bench and a torque measurement method thereof. Background technique [0002] In the past, the torque sensor was mainly used to measure the steady-state torque value during operation. It is difficult to measure the torque value at the moment of starting, because the moment from the standstill to the start of the motor is very short, and the sampling frequency of the ordinary torque sensor cannot effectively collect the torque at the moment of starting. value, and the torque value measured for instant start is not the maximum torque value displayed by the torque sensor, because the moment of inertia of the motor to the spindle is also included during start-up, resulting in inaccurate measurement results, so even if the torque sensor captures the maximum torque value is not The torque value at the moment of starting.

[0002] In the past, the torque sensor was mainly used to measure the steady-state torque value during operation. It is difficult to measure the torque value at the moment of starting, because the moment from the standstill to the start of the motor is very short, and the sampling frequency of the ordinary torque sensor cannot effectively collect the torque at the moment of starting. value, and the torque value measured for instant start is not the maximum torque value displayed by the torque sensor, because the moment of inertia of the motor to the spindle is also included during start-up, resulting in inaccurate measurement results, so even if the torque sensor captures the maximum torque value is not Torque value at the moment of starting

[0003] The measurement of the torque value in the prior art is usually to measure the steady-state torque value during operation, that is, to detect the temperature and dynamic torque of the detected bearing when it is rotating, to obtain the bearing temperature detection data and the bearing dynamic torque detection data; through real-time monitoring of the bearing temperature Data and bearing dynamic torque data to determine whether the detected bearing is damaged, and the influence of the torque value of the bearing at the moment of motor startup has not yet appeared on its performance, so it cannot provide a reference for designing bearings with better performance
