Service life test equipment and method capable of realizing multidirectional stress of motor

Abstract

The invention discloses service life test equipment and method capable of realizing multidirectional stress of a motor. The equipment comprises a sliding table type stress device, a motor clamping device, a control box and a to-be-tested motor, wherein the to-be-tested motor is located between the sliding table type stress device and the motor clamping device; the motor clamping device comprises aV-shaped movable upper plate and a V-shaped movable lower plate which are oppositely arranged in the vertical direction; the V-shaped movable upper plate and the V-shaped movable lower plate move oppositely in the vertical direction; the sliding table type stress device comprises a sliding table assembly, a pulley assembly and a motor shaft connecting assembly; horizontal axial force and radial force are applied to a shaft of a to-be-tested motor through gravity; a hysteresis brake is arranged on the sliding table assembly to apply rotating torsion; and the control box controls a power sourceof the to-be-tested motor and the hysteresis brake. A forward thread sleeve and a reverse thread sleeve enable the V-shaped movable upper plate and the V-shaped movable lower plate to concentricallyclamp the to-be-tested motor, the sliding table type stress device enables the gravity of the first weight to be converted into pressure or tension through the pulley and the sliding plate, and the motor shaft is subjected to radial force through the gravity.

Description

technical field [0001] The invention relates to the field of motor testing equipment, in particular to a life testing equipment and method capable of realizing multi-directional force of a motor. Background technique [0002] In the current motor life test, the traditional method is to use the fan blade to simulate the load for the life test. For tests with special requirements, such as the output shaft of the motor is required to be subjected to a certain rotational torque, axial force or radial force, None of the traditional methods can achieve these test requirements, resulting in inaccurate test results, affecting new product development progress, increasing development costs or causing project failure. SUMMARY OF THE INVENTION [0003] In order to solve the deficiencies in the prior art, the present invention provides a life test equipment that can realize the multi-directional force of the motor. Test requirements, improve the accuracy of motor life test results. ...
