Magnetic pole supporting block assembling device for steel rolling motor rotor

Abstract

The invention discloses a magnetic pole supporting block assembling device for a steel rolling motor rotor. The device comprises a rotor magnetic pole and a magnetic pole supporting block, wherein therotor magnetic pole comprises a magnetic pole coil and a rotor iron core; an insulation board is arranged between the magnetic pole supporting block and the magnetic pole coil; the magnetic pole supporting block is connected to the rotor iron core through a supporting block bolt; the rotor magnetic pole is provided with a spacing device; the spacing device comprises a baffle, a first pull rod, asecond pull rod and a nut, wherein the baffle is arranged on the outer cylindrical surface of the rotor magnetic pole; the lower end of the first pull rod and the lower end of the second pull rod areindependently provided with a bent flange; the lower end of the first pull rod and the lower end of the second pull rod independently tightly hook the lower ends of the insulation boards on two sidesof the magnetic pole supporting block; and the upper end of the first pull rod and the upper end of the second pull rod penetrate through the baffle and are in screwed connection with the nut. By useof the assembling device, the magnetic pole supporting block and the insulation board do not generate relative slippage, and therefore, the rotor magnetic pole can more easily meet the magnetic pole supporting block assembling requirements of the steel rolling motor rotor.

Description

technical field [0001] The invention relates to the technical field of synchronous motors, in particular to an assembly device for rotor magnetic pole support blocks of synchronous motors with alternating frequency and frequency conversion. Background technique [0002] The synchronous motor for rolling steel with AC frequency conversion is a trial-manufactured product developed and designed on the basis of absorbing the mature structure of rolling motors at home and abroad. The circumferential limit of the rotor magnetic poles is realized by wedge-tight installation of the support blocks, that is, the aluminum support blocks are used to fix the magnetic poles to prevent the magnetic poles from loosening that may occur due to thermal deformation, mechanical impact, and electromagnetic effects during operation. Make the entire magnetic pole of the motor form a whole, prevent the inter-turn insulation of the magnetic pole coil from being damaged due to relative displacement, s...

AI Technical Summary

Problems solved by technology

In the process of applying pre-tightening force to the support block, slippage will occur between the pole support block and the insulating plate, resulting in failure of the insulation between the support block and the coil

Moreover, the downward sliding of the insulating plate will push away the magnetic pole supporting plate, causing damage to the magnetic pole supporting plate, and the assembly quality of the magnetic pole supporting block cannot be guaranteed, which will cause the AC frequency conversion steel rolling synchronous motor to be easily damaged or the efficiency will be reduced.
