Service life testing device for magnetic damping type motor

Abstract

The invention relates to a service life testing device for a magnetic damping type motor. The device comprises a connecting sleeve, a flat key, a transmission sleeve, a fixed plate, a bottom plate, amagnetic damper and a connecting plate. The fixed plate is vertically installed on the bottom plate through screws to form a base supporting system, and a positioning hole is formed in the fixed plate. The magnetic damper is fixed to one side of the fixed plate through screws. An output shaft of the magnetic damper penetrates through the positioning hole and extends to the other side of the fixedplate, the output shaft of the magnetic damper is matched with one end of the transmission sleeve through the flat key, and the other end of the transmission sleeve is matched with a motor output shaft. Positioning bosses are arranged on two sides of the connecting plate respectively, a boss on one side of the connecting plate is matched with the positioning hole of the magnetic damper, and the other side of the connecting plate is matched with an inner hole of the connecting sleeve. The connecting sleeve comprises a circular ring part, a plurality of supporting legs extend from an end face ofone end of the circular ring part and are fixed to the connecting plate, and the motor is installed on an end face of the other end of the circular ring part. The load is adjustable, motor scrappingis not caused, the reliability is high, and a structure is convenient to replace.

Description

Technical field [0001] The invention belongs to the field of product reliability testing, and specifically relates to a magnetic damping motor life testing device, which provides a convenient and reliable testing device for the prophase program verification of new motor product development and subsequent product design and process changes. Background technique [0002] For the life test of the magnetic damping motor, the current commonly used methods include the motor manufacturer's use of motor tow, dynamometer and client practical application life test, etc. The first two methods have limitations, and the life test cost is high. The towed motor can only be scrapped after the test, which causes the accuracy of the dynamometer equipment to decrease or even damage. The actual test method is used when the customer cannot provide the terminal application. Can't proceed. Summary of the invention [0003] The present invention provides a magnetic damping type motor life test device, w...
