Braking device for motor driven mechanism

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 relates to a braking device of a mechanism driven by a motor, which belongs to the field of braking devices for motors. Background technique [0002] After the power is cut off, the motor needs to rotate for a period of time (or distance) to stop depending on the inertia, and the hook of the crane or the basket of the hoist in production requires accurate positioning; the spindle of the universal milling machine is required to be able to stop quickly; Safety protection and accurate positioning control are required...etc. All of these need to brake the dragged motor. The so-called braking is to give the motor a torque opposite to the direction of rotation to make it stop rapidly (or limit its speed). There are generally two types of braking methods: mechanical braking and electrical braking. [0003] The commonly used method of mechanical braking: electromagnetic brake, electromagnetic brake, electromagnetic brake is to rely on the frict...

Problems solved by technology

[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
