Abstract

The invention relates to a torque calibration test bed for a loader transmission shaft. The test bed mainly comprises a power module, a speed reducing module, a torque sensor, a switching module and an end part supporting module, wherein a motor in the power module is connected with a speed reducer in the speed reducing module through a shaft coupling; the speed reducer realizes gear transmission with a central shaft through a pinion and a large toothed sector; the central shaft is arranged on a bearing seat bracket through a bearing and a bearing seat; the torque sensor is coaxially fixed between the central shaft and a left deformed ring flange in the switching module through a flange; and a right deformed ring flange of the switching module is connected with a slipway of the end part supporting module in a sliding way through a slide block on a right deformed ring flange bracket. The limit of manual torque loading is overcome, the test bed is suitable for calibrating torques of loader transmission shafts of different specifications and different lengths, and quick calibration of the torques of different types of loader transmission shafts is realized.

Description

Technical field: [0001] The invention belongs to the technical field of torque calibration, and in particular relates to a loader transmission shaft torque calibration test bench. Background technique: [0002] The loader transmission shaft is an important part of the loader transmission system. There are cross couplings and flanges at both ends. The front flange and the gearbox output shaft flange are connected by bolts. The rear end flange is connected to the drive axle input shaft Flanges are connected by bolts. [0003] In the process of collecting the load spectrum of the drive train of the loader, the main task is to measure the torque signal of the drive shaft, and it is necessary to measure the torque signal of the drive shaft of the loader under different models and various industries. In the prior art, the torque measurement of the drive shaft of the loader mostly adopts the strain gauge torque measurement method, and the strain gauge used to test the torque needs...
