Disc brake motor for rotary whirley

Abstract

The invention discloses a disc brake motor which replaces the traditional electromagnetic braking asynchronous motor to be used for a rotary whirley. The disc brake motor is characterized in that the cores of a stator and a rotor are disc-shaped; stator windings embedded in a radial shape and centrifugal cast aluminium conducting bars are arranged at end faces; an annular asbestos-free brake sheet is glued on the back face of the stator; and a brake spring is arranged between the stator and the rotor. The disc brake motor has the function of operating normally under electrification condition and quickly braking at the moment of power failure; the engine base and the rotating shaft of the disc brake motor are arranged to substitute the terminal pad and the rotating shaft of a speed reducer; the disc brake motor is directly embedded into the speed reducer to be combined with the speed reducer into a whole, thus the structure is simplified, the volume of the integral structure is reduced, mechanical and electrical integration is realized, the systematic precision and reliability are enhanced, the length of the original motor and the speed reducer which are connected is shortened to 354mm from 437mm, and the weight is lightened to 53.5kg from 61.6kg; and the invented disc brake motor for a rotary crane hoister has the advantages of novel structure, small size, light weight, short axial and radial dimensions, flexible braking, accurate position and beautiful integral structure.

Description

technical field [0001] The present invention relates to a brake motor for overhauling the main engine of a slewing jib crane for wind power generation. As the capacity of a single unit of wind power generation equipment continues to increase, the difficulty of maintenance and safety hazards increases. Due to the limitation of space in the tower, it is required to provide a Type, novel and compact structure, short axial dimension, small size, light weight, rapid braking, accurate positioning, reliable operation, convenient maintenance, YHHP1100 disc brake motor for slewing jib crane. Background technique [0002] The original wind power generation equipment uses the traditional electromagnetic brake asynchronous motor for the maintenance of the main engine of the slewing jib crane with wind power. A DC electromagnetic brake is added between the rear end cover of the motor and the fan. The motor and the reducer are assembled separately and are independent of each other. The sp...

[0002] The original wind power generation equipment uses the traditional electromagnetic brake asynchronous motor for the maintenance of the main engine of the slewing jib crane with wind power. A DC electromagnetic brake is added between the rear end cover of the motor and the fan. The motor and the reducer are assembled separately and are independent of each other. The space area is large, the overall appearance installation structure is bulky and heavy, the axial and radial dimensions are large, the structure is clumsy, and the appearance is not aesthetically pleasing
