Abstract
The utility model belongs to the electric machine fields, specifically speaking is a bisurface side magnetic electric machine brake, which comprises a casing, a key which is fixed with the casing, a brake disk, a rotor shaft and a magnet. The magnet is fixed on the rotor shaft; a spring is between the brake disk and the magnet; a friction disk is on the other side of the brake disk. The utility model is characterized in that: a brake block is on the other end of the friction disc; the friction disc and the brake block enwrap the rotor shaft and only do the axially moving; a friction surface which is among the friction disc, the brake disk and the brake block is double-sided friction, the friction disc and the brake block only do axially moving. The structure of the utility model is reasonable, the friction disc double-sided contacts with the brake block and the brake disk, the friction area is big and the braking effect is good.
Description
Technical field
The utility model belongs to electric machinery, specifically is a kind of two-sided other magnetogenerator break.
Background technique
At present, electromotor brake commonly used is the single face break, and the break of this structure is provided with an active face and a stationary plane, and motor plays braking effect by the friction of active face, because surface of contact is less in the braking process, braking effect is bad.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of two-sided other magnetogenerator break of rational in infrastructure, good braking effect is provided.
The technical solution of the utility model is as follows:
A kind of two-sided other magnetogenerator break, comprise casing, with fixing key, brake disc, rotor shaft, the suction iron of casing, inhale ferropexy on rotor shaft, between brake disc and the suction iron spring is arranged, the brake disc opposite side has wearing piece, it is characterized in that: the other end of wearing piece has brake block, wearing piece, brake block are sleeved on the rotor shaft, can only do axial motion, between wearing piece and brake disc, the brake block attrition surface be arranged, be two-sided friction.
The utility model is when the motor no electric circuit, because the active force of spring, brake disc is toward brake block and the motion of wearing piece direction, wearing piece is contacted on attrition surface with brake disc, brake block respectively, play the effect of two-sided contact, thereby increased frictional force, rotor shaft can not rotate; When energising, the rotor shaft rotation makes suction iron cutting magnetic line and produces suction, brake disc is sucked back with inhaling iron contact, thereby makes wearing piece and brake disc, brake block break away from attrition surface, and rotor shaft just can freely rotate like this.The utility model is rational in infrastructure, wearing piece with brake block, brake disc is two-sided contacts, the friction area is big, good braking effect.
Description of drawings
Fig. 1 is the utility model internal structure schematic representation.
Embodiment
As shown in Figure 1, a kind of two-sided other magnetogenerator break, comprise casing 1, with fixing key 2, brake disc 3, the rotor shaft 4 of casing, inhale iron 6, inhale iron 6 and be fixed on the rotor shaft 4, between brake disc 3 and the suction iron 6 spring 5 is arranged, brake disc 3 opposite sides have wearing piece 8, it is characterized in that: the other end of wearing piece 8 has brake block 7, and wearing piece 8, brake block 7 are sleeved on the rotor shaft 4, can only do axial motion, between wearing piece 8 and brake disc 3, the brake block 7 attrition surface A, B are arranged, be two-sided friction.
The utility model is when the motor no electric circuit, because the active force of spring 5, brake disc 3 is toward the motion of brake block 7 directions, brake disc 3 continues to promote wearing piece 8 motions, and wearing piece 8 is contacted with the B face at the A face with brake block 7 with brake disc 3 respectively, because two-sided friction contact has increased frictional force, and rotor shaft 4 can not be moved.
When energising, the rotor shaft rotation makes suction iron 6 cutting magnetic lines and produces suction, brake disc 3 is sucked back with inhaling iron 6 contact at the C face, thereby attrition surface A, B are unclamped, and rotor shaft 4 just can freely rotate like this.
