Abstract
The utility model relates to an electromagnetic brake motor, which comprises a main body of a motor, wherein a fan is arranged on a rotating shaft outside a back end cover of the main body of a motor; an electromagnetic brake device is arranged on the rotating shaft between the back end cover and the fan. The electromagnetic brake device comprises an electric magnet, a brake spring, an armature, a brake disk and a positioning plate, wherein the brake disk is provided with a disk core; a splined hole is arranged in the middle of the disk core; friction material layers are attached on two disk faces of the disk core. A plurality of ventilation holes are arranged on the disk core between the splined hole and the friction material layers in a shaft direction; fan grooves are arranged on the friction material layers along the radical direction of the disk core. Thereby, the brake disk also has a function of a centrifugal fan; wind flow can carry heat generated by frictional brake out of the brake for heat radiation after the motor drives the brake disk to rotate. Under the condition of frequence starting and braking, the temperature of the brake disk and the armature, and the positioning plate can be reduced; the utility model solves the problems that the bearing in the motor end cover is overheating, lubricating grease is leaked, the temperature rise of windings is increased and the motor is damaged.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of electromagnetic braking motor.
Background technology
Electromagnetic braking motor of the prior art, it comprises motor body, in the rotating shaft of the rear end cap outside of motor body, fan is housed, in the rotating shaft between rear end cap and the fan electro-magnetic braking device is housed, the problem of its existence is: the electromagnetic braking motor is at Fraquent start, under the braking situation, the brake disc of brake and the frequent friction catch of electromagnetic braking End cover for motor, accumulation has produced a large amount of heats, cause the bearing in the electromagnetic braking End cover for motor seriously overheated, lubricating grease rushes down leakage in a large number, winding temperature increases, and influences bearing of motor and life of winding, damages the electromagnetic braking motor.
Summary of the invention
The technical problems to be solved in the utility model is, at the deficiencies in the prior art, proposed a kind of electromagnetic braking motor of good heat dissipation effect, and it has protected bearing of motor and winding, is particularly useful for the occasion of Fraquent start.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of electromagnetic braking motor, it comprises motor body, in the rotating shaft of the rear end cap outside of motor body, fan is housed, in the rotating shaft between rear end cap and the fan electro-magnetic braking device is housed, described electro-magnetic braking device comprises electromagnet, tripping spring, armature, brake disc and location-plate, be characterized in: described brake disc is provided with the dish core, dish core middle part is provided with splined hole, two cards of dish core are attached with friction material layer, axially have some ventilation holes on the dish core between splined hole and the friction material layer, radially have a fan groove at friction material layer upper edge dish core.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, the magnet spool cover is fixed with one with the motor body rear end cap, magnet spool is contained in the coil cover, be contained in armature in the rotating shaft for slip cap after the electromagnet, be provided with tripping spring between armature and the coil cover, after the armature is the brake disc of fixedlying connected by spline with rotating shaft, be provided with location-plate between brake disc and the fan, described location-plate joins by carrying bolt and magnet spool cover.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, the outer rim of electromagnet coil cover, armature, location-plate is provided with radiating ribs, the radiating ribs of electromagnet coil cover, armature, location-plate outer rim is provided with the carrying bolt connecting hole, and described tripping spring is installed between the radiating ribs of the radiating ribs endoporus of electromagnet coil cover and armature.
The utility model compared with prior art is axially arranged with ventilation hole on the dish core of the brake disc of electro-magnetic braking device, radially has a fan groove along dish.Make brake disc have the effect of centrifugal fan concurrently, the heat that the wind flow that produces after the motor drives brake disc rotates produces friction catch is taken brake out of and is dispelled the heat outward.The magnet spool cover is fixed with one with the motor body rear end cap in addition; brake disc and location-plate are located at electromagnet afterwards near the fan place; make brake disc not with the End cover for motor friction catch; avoided the frictional heat of brake apparatus to be directly transferred to motor body; protected bearing of motor, the winding can be not too high, prolonged the useful life of bearing of motor and winding because of the frictional heat temperature.By experiment, the frictional heat that electromagnetic braking motor of the present utility model is produced is under the acting in conjunction of brake disc centrifugal fan groove and motor shaft end fan, taking motor rapidly out of dispels the heat outward, under the situation of Fraquent start, braking, greatly reduce the temperature of brake disc, armature, location-plate, the bearing that has solved in the End cover for motor is seriously overheated, and lubricating grease rushes down leakage in a large number, winding temperature rise increases, the problem that motor damages.
