[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a braking device of a motor-driven mechanism to solve the problem that the friction force of the electromagnetic brake depends on the spring to achieve enhancement. The spring is easy to age after a long service time and reduces the friction force. Braking energy loss is large, unable to meet the needs of the existing market

Abstract
The invention discloses a braking device for a motor driven mechanism. The braking device has a structure that includes a rotating shaft, a rotor core, electric brushes, a bearing, a commutator segment, a rear end cover, a housing, a stator winding, a stator core, a winding coil, an iron core, a coil, an armature, rollers I, an upper guide rail, a limit block, an upper brake pad, a blade, a connecting rod I, a lower brake pad, rollers II, a lower guide rail, a front end cover, a spring, a slotting, a baffle, a vertical plate, connecting rods II, and a hinge. The rear end cover is embedded to the rear end of the housing. The front end cover is arranged at the front end of the housing and connected with the housing through a bolt. The rotating shaft penetrates through the front end cover. The rotating shaft is arranged on the central axis of the housing. According to the invention, the braking device for the motor driven mechanism is capable of quickly braking the rotating shaft throughthe upper brake pad and the lower brake pad, with small energy loss and with no need to worry about the aging of the spring, the spring at the bottom of the lower brake pad enables the lower brake padto rise more quickly, and through the acceleration of the rising process, the rotating shaft can be quickly braked.
Description
Technical field [0001] The invention is a brake device of a motor-driven mechanism, belonging to the field of motor brake devices. Background technique [0002] After the motor is cut off the power supply, it takes a period of time (or distance) to rotate by inertia, and the hook of the crane or the hanging basket of the hoist in production requires accurate positioning; the main shaft of the universal milling machine is required to stop quickly; the elevator is stopped after a sudden power failure Need safety protection and accurate positioning control...etc. All of these need to brake the driving motor. The so-called brake is to give the motor a torque opposite to the direction of rotation to make it stop quickly (or limit its speed). There are generally two types of braking methods: mechanical braking and electrical braking. [0003] Common methods of mechanical braking: electromagnetic brake, electromagnetic brake, electromagnetic brake is the brake wheel by the friction plat...
