Abstract
The utility model discloses a permanent magnet brake. In order to solve the braking problem of the prior door rolling machine with a DC motor and the like, the permanent magnet brake consists of a shell (1), magnets (3), a brake pad (2), steel balls (5) and a shaft coupling (4), wherein the shell (1) is connected with a motor through screws, and the driving shaft of the motor passes through the shell (1) and is connected with one end of the shaft coupling (4); the other end of the shaft coupling (4) is connected with a speed reducer, and the shaft coupling (4) also passes through the brake pad (2) and is movably connected with the brake pad (2); and the brake pad (2) is arranged in the shell and is contacted with the shell (1) through the magnet (3), and the positioning steel balls (5) are arranged at the two sides of the brake pad (2) in the shell (1). Accordingly, the utility model has the advantages of reliable braking, convenient maintenance and the like.
Description
Affiliated technical field
The utility model relates to a kind of rolling machine braking device that adopts direct current generator, especially relates to a kind of permanent magnet braking device.
Background technique
At present, a kind of like this rolling machine that adopts direct current generator is disclosed on the market, its braking device is: the governor control characteristics that makes full use of direct current motor is slowed down, reach the braking purpose, adopt this structure after because the effect of machinery inertial, when taking emergency braking promptly to cut off the electricity supply, rolling machine also can continue operation, therefore, and the component on the fragile rolling machine.
Summary of the invention
The purpose of this utility model provides a kind of volume permanent magnet braking device little, simple in structure.
For achieving the above object, the utility model permanent magnet braking device, form by housing, magnet, brake block, steel ball and coupling, housing is connected with motor by screw, and coupling one end that motor transmission shaft passes in housing and the housing is connected, and the coupling the other end is connected with retarder, coupling also passes brake block and is movably connected with brake block, brake block is arranged in the housing, and contacts with housing by magnet, and the brake block both sides in housing are provided with positioning ball.
Be processed with the internal tooth that meshes with the retarder planetary pinion at coupling one end position of center line, porose in the processing of coupling the other end position of center line, see that from cross section the outer surface of coupling should be processed into spline-like.
Also be provided with on the brake block can with the corresponding magnet of magnet on the housing, and be processed with the hole of spline-like in the brake block central position.
After adopting this structure, when direct current generator turned round, motor shaft drove the coupling high speed rotating, because action of centrifugal force, made brake block on the coupling break away from the magnet suction on the housing and rotated; When cutting off the electricity supply, the rotating speed of direct current generator reduces, and the centrifugal force that is produced also diminishes, and is final because the effect of magnet is adsorbed on the housing brake block, and by the steel ball location, thereby reach the emergency braking purpose.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the main cross-sectional schematic of the utility model permanent magnet braking device.
Fig. 2 is the schematic top plan view of the utility model permanent magnet braking device.
