Abstract
The utility model discloses a motor, comprising a shaft, a first bearing, a second bearing, a stator and a rotor. The shaft traverses the first bearing; the second bearing is fixedly arranged on the rotor; the stator is fixedly arranged on a back cover; and the second bearing is fixedly arranged on the back cover. The motor is characterized in that the rotor is provided with a second groove and several first grooves, the front end of the rotor is provided with a brake device, the brake device comprises a friction plate, a brake plate and a pressure spring, the friction plate is fixedly arranged on a front cover, the brake plate is sleeved on the shaft, the brake plate is provided with several bosses, the bosses are engages with the first grooves on the rotor, and the pressure spring is disposed in the second groove of the rotor. According to the utility model, the structure is simple, and the motor is stopped in time when power is off.
Description
(1) technical field
The utility model relates to a kind of brake motor, belongs to machine field.
(2) background technology
Brake motor can be divided into the direct current brake motor, exchanges brake motor.The direct current brake motor need to be installed rectifier, and electric machine structure is simple, low cost, and the heating ratio is very fast, easily motor damage.Exchanging brake motor does not need rectification, but its electric machine structure is complicated, and cost is high.
Existing brake motor action principle is: when electrical power, add solenoid and produce axial magnetic control power, make armature overcome acting force of the spring, axially leave the friction plate of brake wheel, the motor rotation is when motor cuts off the power supply, solenoid is shaftless to magnetic control power, armature contacts with the friction plate of brake wheel under the pressure-acting of spring, produces axial friction, and motor is stopped gradually.Said motor has solenoid power consumption, easy burn-out; The electromagnetic brake complex process, cost is high.
(3) summary of the invention
The utility model purpose is that the shortcoming for above prior art exists provides a kind of nothing to add the motor that coil can be realized brake function, solves the high problem of easy burn-out, cost of existing motor.
The technical solution used in the present invention is: a kind of motor, comprise axle, clutch shaft bearing, the second bearing, stator, rotor, axle passes clutch shaft bearing and the second bearing is fixed on the rotor, stator is fixed on the bonnet, the second bearing is fixed on the bonnet, it is characterized in that: rotor is provided with the second groove and some the first grooves, the rotor front end is provided with brake gear, described brake gear comprises friction plate, brake block, compression spring, friction plate is fixed on the protecgulum, and brake block is enclosed within on the axle, and brake block is provided with some projections, projection and epitrochanterian the first engagement, compression spring places in the second groove of rotor.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in: motor is easy burn-out, safe and reliable not, the simple and low cost of manufacture of electric machine structure.
(4) description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of the utility model brake block;
(5) embodiment
Below in conjunction with specific embodiment structure of the present utility model is described further.
As shown in the figure, a kind of motor, comprise axle 1, clutch shaft bearing 2, the second bearing 10, stator 11, rotor 9, axle 1 passes clutch shaft bearing 2 and the second bearing 10 is fixed on the rotor 9, stator 11 is fixed on the bonnet 13, the second bearing 10 is fixed on the bonnet 13, it is characterized in that: rotor 9 is provided with the second groove 7 and some the first grooves 6, rotor 9 front ends are provided with brake gear 14, and described brake gear 14 comprises friction plate 3, brake block 4, compression spring 8, friction plate 3 are fixed on the protecgulum 12, brake block 4 is enclosed within on the axle 1, brake block 4 is provided with some projections 5, the first groove 6 engagements on projection 5 and the rotor 9, and compression spring 8 places in the second groove 7 of rotor 9.
Operation principle of the present utility model is: during energising, brake block moves down rapidly under the effect of the magnetic force that motor produces, projection on the brake block and epitrochanterian the first engagement, brake block breaks away from friction plate, and during outage, motor has not had magnetic force, brake block moves up under the effect of compression spring and contacts with friction plate, brake block is connected with epitrochanterian the first groove by projection, because the effect of frictional force, brake block drive motor rotor stops operating.
