Embodiment Construction
[0013] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.
[0014] A kind of armored vehicle transmission device test bench high torque in-situ calibration method proposed by the present invention is characterized in that it comprises the following steps:
[0015] S1. First place the large torque power output system on the test bench where the test piece is installed, then install the standard torque sensor, fix the other end of the standard torque sensor to one end of the transmission shaft through tooling, and finally adjust it to be concentric;
[0016] The high-torque power output system uses a PLC-controlled servo motor as the power source to achieve stable and precise high-torque power output. The high-torque power output system is fixedly connected with the channel steel;
[0017] High-torque power output system includes PLC, servo...

The invention relates to a large-torque in-situ calibration method for an armored vehicle transmission device test bed, and the method comprises the steps: firstly, placing a large-torque power outputsystem at a position, where a test piece is installed, of the test bed, then, installing a standard torque sensor, and enabling a lossless connection braking device to be disposed at the other end ofa transmission shaft for enclasping and braking of the transmission shaft; and when the large-torque power output system loads torque, reading numerical values of a standard torque sensor and a measured sensor on the transmission shaft, and carrying out comparison to judge whether the measured sensor is out of tolerance or not. According to the invention, in-situ calibration of the large torque of the test bed is realized under the condition that the system firmness is not changed and the use conditions are consistent, and the problem of in-situ calibration of the large torque of the test bedof the armored vehicle transmission device with the torque value greater than 3000Nm is solved.
Description
technical field [0001] The invention belongs to the field of torque calibration, and in particular relates to a large torque in-situ calibration method for an armored vehicle transmission test bench. Background technique [0002] The armored vehicle transmission test bench is a special test equipment for armored vehicle scientific research test and transmission component acceptance inspection. The torque speed sensor installed on the test bench is mainly used to measure the technical indicators such as no-load loss, transmission power and transmission efficiency of the comprehensive transmission device. , The measurement results are directly related to the product quality. In the past, the calibration of the high-torque speed sensor was usually to remove it from the test bench and send it to the laboratory for calibration on the standard machine. First of all, the accuracy of the test results of the armored vehicle transmission test bench is not only related to the accuracy...
