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

Revolution whilrley crane disc type brake motor

Technical field

The present invention relates to a kind ofly use braking motor for the maintenance of wind power generation revolution whilrley crane main frame, along with the wind energy generating plant single-machine capacity continues to increase, maintenance and the increase of maintenance difficulty potential safety hazard, because limited space in the tower tube, it is a kind of that requirement provides, novel structure, compactness, and axial dimension is short, volume is little, in light weight, braking is rapid, and accurate positioning is reliable, easy to maintenance, revolution whilrley crane YHHP1100 type disc type brake motor.

Background technology

Former wind energy generating plant is owing to be to add a direct current electromagnetic brake between the rear end cap of motor and fan with the maintenance of wind power generation revolution whilrley crane main frame with traditional electrical magnetic brake asynchronous motor, motor and reductor split assembling, separate, the area that takes up room is bigger, bulk shape mounting structure volume, weight are big, axially, radial dimension is big, the structure clumsiness, outward appearance does not have aesthetic feeling.

Summary of the invention

The objective of the invention is to provide a kind of novel suitable wind power generation main frame maintenance revolution whilrley crane usefulness, novel structure, compactness, axial dimension is short, volume is little, in light weight, braking is rapid, accurate positioning, reliable, easy to maintenance, outward appearance is pursued the YHHP1100 type disc type brake motor of aesthetic feeling.

For realizing purpose of the present invention, a kind of revolution whilrley crane provided by the invention substitutes traditional electrical magnetic brake asynchronous motor with YHHP1100 type disc type brake motor and merges into a single whole with the reductor structure, realizes electromechanical integration.

1, the disc type brake motor is fixed, rotor core is disc, end face has radial groove to embed stator winding and centrifugal aluminum casting sliver, the rotor back side is bonded with annular non-asbestos brake block, fixed, tripping spring is housed between the rotor, behind electrical power, fixed, between the rotor except that generation makes the disk type rotor turning moment, also produce axial magnetic pull simultaneously, under the effect of axial force, disk type rotor axial displacement, compression spring, the releasing of brake sheet, the motor entry into service, when outage, axial force disappears, the rotor of strap brake sheet produces braking moment under the effect of compression spring, motor is shut down rapidly, and casing is fixed on the electric machine stand, cover rotor and and the ring-shaped brake sheet between keep braking gap.

2, terminal pad, the rotating shaft of decelerator are removed, substitute by electric machine stand, rotating shaft, expanded motor support thickness is increased to 32mm by 10mm, machine shaft is lengthened to 70mm by 30mm, changing flat key into by spline connects, be easy to processing, motor directly embeds in the reductor, and motor and reductor merge into a single whole, and have dwindled volume, simplify the structure, improved system accuracy and reliability, the length dimension after making original motor and reductor being connected shortens to 354mm by original 437mm, weight reduces to 53.5Kg by original 61.6Kg.

3, adding outside framework oil seal φ 47 * φ 20 * 10 in the disc type brake electric machine stand seals, prevent to enter in the motor cavity with lubricating oil after reductor is connected, motor end play adopts the hole to position with back-up ring 47 and shaft block ring 20, guarantees the electric clearance and the braking gap of motor.

4, motor shaft extension end directly gos deep in the reductor hole, add 304 radial ball bearings at motor shaft extension end and support the location, prevent because motor shaft extends through length, when the driven by motor decelerator turns round, produce not bad phenomenon such as steadily shake, the reliability and the fail safe that have improved motor.

5, the revolution whilrley crane after the invention is formed one with YHHP1100 type disc type brake rotor and brake block, substitute traditional electrical magnetic brake asynchronous motor, the electric machine structure novelty, volume is little, and is in light weight, axial dimension is short, braking is flexible, and accurate positioning having the normal operation of energising, instantaneous the stopping of cutting off the power supply stopped fast function, makes overall structure pursue aesthetic feeling.
