A multifunctional v-belt torque fatigue testing machine

Abstract

The invention discloses a multifunctional V-belt torque fatigue testing machine and belongs to the field of testing equipment. The multifunctional V-belt torque fatigue testing machine consists of a 22Kw variable frequency motor, a 30Kw direct current motor, check belt wheels, a first pressure belt wheel, a second pressure belt wheel, a driving wheel, a driven wheel, a check belt, a displacement sensor, a torque sensor, a weight, an upper linear guide rail, a lower linear guide rail, linear bearings, guide rail brackets, a transmission wheel group, an electric control cabinet, vertical guide rails, a suspension motor bracket, a machine body, a guide wheel and an electric heating constant temperature box. A testing process is controlled and calculated by a computer; a frequency converter and a direct current controller are respectively driven by a master motor and a slave motor for speed regulation; a testing specification meets using requirements for two-wheel tests and four-wheel reversed bending tests in a GB / T12735-91 V-belt fatigue testing method for agricultural machinery and relevant transmission belt two-wheel torque fatigue tests specified in standards.

Description

technical field [0001] The invention relates to a V-belt fatigue testing machine, specifically a multifunctional V-belt torque fatigue testing machine composed of a motor, a pulley, a sensor and the like, belonging to the field of testing equipment. Background technique [0002] The multifunctional V-belt (with torque) fatigue testing machine is based on the German Shaw company's pulley belt (with torque) fatigue testing machine combined with the "V-belt fatigue test method for agricultural machinery", combined narrow V-belt HG / T2819- In 1996, the car V-belt GB / T11545-2008 was designed and manufactured. At present, there are few multi-functional V-belt testing machines, and the technology is not mature. For the fatigue test of V-belts, because V-belts are greatly affected by the ambient temperature, the current fatigue testing machine has no reasonable and effective measures for such problems. At the same time, the control system is simple and the signal acquisition is inacc...

[0002] The multifunctional V-belt (with torque) fatigue testing machine is based on the German Shaw company's pulley belt (with torque) fatigue testing machine combined with the "V-belt fatigue test method for agricultural machinery", combined narrow V-belt HG / T2819- In 1996, the automobile V-belt GB / T11545-2008 was designed and manufactured. At present, there are few multi-functional V-belt testing machines, and the technology is not mature. For the fatigue test of V-belts, because V-belts are greatly affected by the ambient temperature, the current fatigue testing machine has no reasonable and effective measures for such problems. At the same time, the control system is simple and the signal acquisition is inaccurate. Improve the measurement performance of the V-belt testing machine, design and manufacture a multi-functional V-belt torque fatigue testing machine, but there is no such tool in the market at present
