The purpose of this utility model can realize by following technical proposal: the brake gear in a kind of brake deceleration motor, comprise brake wheel that is fixed on the machine shaft and the fixed disk that is fixed on the motor housing, between fixed disk and brake wheel, be provided with and be socketed in the rotating shaft and the armature disc that can in rotating shaft, slide, in fixed disk, be provided with solenoid, it is characterized in that, be provided with between fixed disk and armature disc edge and make armature disc withstand on some springs on the brake wheel, the edge of described brake wheel is provided with the adjusting device that can regulate distance between brake wheel and the fixed disk.
Brake gear in this brake deceleration motor is regulated brake clearance with the spacing of regulating between brake wheel and the fixed disk.Fixed disk is fixed on the motor housing, and brake wheel is fixed in the rotating shaft, along with rotating shaft is rotated together.Behind this brake deceleration electric motor starting, solenoid gets electric, produces magnetic force armature disc is attracted, make armature disc slide and be resisted against on the fixed disk to fixed disk, like this, just have the gap between armature disc and the brake wheel, brake wheel can freely rotate with the rotating shaft of motor.After this brake deceleration motor cut out, the solenoid dead electricity under the effect of spring, made armature disc slide and be resisted against on the brake wheel to brake wheel, and armature disc and brake wheel produce static friction, realize the braking of motor.Brake wheel can be worn away gradually by armature disc, causes brake clearance to become big, at this moment, can regulate distance between brake wheel and the fixed disk by adjusting device, brake clearance is dwindled, guarantee the normal brake application of the brake gear in this brake deceleration motor, improve the fail safe of operation.And the moment of torsion when adjusting device is arranged on the edge and increases braking, good braking effect.
In the brake gear in above-mentioned brake deceleration motor, described adjusting device comprises several adjustment screw that are provided with on the brake wheel, and described adjustment screw is passed brake wheel and is connected by screw thread with fixed disk.Rotate adjustment screw and just can regulate the distance that shortens between brake wheel and the fixed disk, simple in structure, easy to adjust.
In the brake gear in above-mentioned brake deceleration motor, it is evenly distributed that described adjustment screw is pressed circumferencial direction, each adjustment screw pass armature disc and with the armature disc matched in clearance, the rotating shaft of armature disc and above-mentioned motor is a matched in clearance.Armature disc does not rotate with rotating shaft, and therefore, the aperture of the centre bore of armature disc is more a lot of greatly than the external diameter of rotating shaft, and like this, adjustment screw passes armature disc, armature disc can be fixed, and simultaneously armature disc is played the effect of guiding.
In the brake gear in above-mentioned brake deceleration motor, described brake wheel comprises brake disc and the friction plate by the rubber making that is connected on the brake disc, and described friction plate is relative with above-mentioned armature disc.This structure can increase frictional force, guarantees that braking in time, prevents to skid.
In the brake gear in above-mentioned brake deceleration motor, described spring is several, and is arranged on the edge of fixed disk equably by circumferencial direction.This structure can make armature disc be pressed in tightly on the brake wheel, increases braking force.
Compared with prior art, the brake gear in this brake deceleration motor has following advantage:
1, the brake gear in this brake deceleration motor is provided with the distance that adjustment screw is regulated armature disc and friction plate, has reduced brake clearance; Simultaneously, screw is used for fixing armature disc again and armature disc is played guide effect, this reasonable in design, compactness.
2, the brake gear in this brake deceleration motor is arranged on the edge of brake disc with screw, and spring is arranged on the edge of fixed disk, and this structure can increase the friction torsion of armature disc to brake disc, and effect is better when skidding.
