Problems solved by technology

[0005] Therefore, from the design of the pneumatic control system, the design of two circuits should be mainly solved: the design of the pneumatic power circuit and the electrical logic control circuit. The experimental machine involves multiple pneumatic cylinder structures. If each cylinder structure passes through the air supply system separately To provide power, not only the operation is cumbersome, but also the production cost of the device is wasted, and the error between the devices is large, which is not conducive to the experimental accuracy of the overall testing machine

Abstract

The invention discloses a pneumatic control system of a bearing service life tester. The pneumatic control system comprises a gas supplying system and a gas using assembly. The gas using assembly comprises a pneumatic system of a transmission device and a temperature control cabinet pneumatic system. The pneumatic system of the transmission device comprises a force exerting air cylinder, a pressure sensor and a precise reducing valve. The pressure sensor is connected to the force exerting air cylinder through a proportional valve. The precise reducing valve is arranged on a connecting pipeline of the force exerting air cylinder and the gas supplying system. The temperature control cabinet pneumatic system comprises a large uncovering air cylinder, two compact air cylinders and two guiding air cylinders, and the five air cylinders are connected to the gas supplying system in parallel through a valve guiding structure. The air cylinder structures of multiple pneumatic devices in the whole set of tester are controlled in an integrated mode through a set of pneumatic control systems, the automation degree of the pneumatic control system is high, operation is easy and convenient, the control pressure of a gas channel is stable, the testing precision of the tester is improved, the using cost of the instrument is saved, and control is convenient to conduct.

Description

technical field [0001] The invention relates to the structural field of a bearing life testing machine, in particular to a pneumatic control system of a bearing life testing machine. Background technique [0002] The new type of bearing life testing machine adopts mechanical, electrical and pneumatic comprehensive control to complete various testing functions of the equipment, among which pneumatic control is an important part of the machine, and its main functions are: 1) The test bearing installed on the testing machine works The temperature requirement is 120±5°C. In order to meet this requirement, the testing machine is equipped with a thermostat with multiple heating pipes to heat it up. The thermostat must be sealed, kept warm and dissipated. For this reason, two compact cylinders are installed on the upper part of the thermostat; two guide cylinders are installed on the bottom of the thermostat, and their function is to open the movable cover when the thermostat excee...
