Abstract
The invention discloses a power-off brake with adjustable air gaps. The power-off brake comprises an electromagnet, an armature, a friction disc and a clamping disc. A spring is arranged between the electromagnet and the armature, an air gap with a distance of 0.2mm to 0.5mm is arranged between the electromagnet and the armature, the friction disc is arranged on the right side of the armature and is placed between the armature and the clamping disc, an air gap adjusting mechanism is arranged at the top end of the power-off brake, a locknut is arranged at the tail end of the air gap adjusting mechanism, the locknut and the clamping disc are arranged tightly, the clamping disc and a pressure spring are arranged tightly, and the clamping disc is arranged between the pressure spring and the locknut. According to the power-off brake with adjustable air gaps, defects in existing air gap adjusting structures are overcome, the simultaneous adjustment of two bolts to guarantee air gap values is not needed, only one locknut is needed to be adjusted, and the adjustment is convenient, rapid and accurate.
Description
Technical field
The present invention relates to the break field, be specifically related to a kind of power-off brake that is easy to regulate air gap.
Background technique
Traditional power-off brake is made up of electromagnet, armature, friction disk and clamping disk, and the air gap of 0.2-0.5mm distance is arranged between electromagnet and the armature.When the coil of electromagnet the inside is connected the power supply of voltage rating, produce magnetic field, armature is attracted near electromagnet left, thereby make friction disk released, realize declutching function; Work as coil blackout, magnetic field disappears, and armature 2 is loaded on the electromagnet upper spring and pushes to the right and be close to friction disk, friction disk is pressed between armature and the clamping disk, thereby realizes band-type brake.
The shortcoming of this mechanism is: the adjustment of air gap is through after the adjustment of adjustment piece nut; Again with locking nut locking, after the adjustment nut is adjusted to suitable location, during locking nut locking; Air gap can change; That is, suitable air gap value must be accomplished by adjustment nut and two parts of locking nut jointly, and the difficulty of adjustment is big, requirement is high, precision is low, efficient is low.
Summary of the invention
Goal of the invention: to the objective of the invention is in order addressing the deficiencies of the prior art, a kind of power-off brake that is easy to regulate air gap to be provided.
Technological scheme: for achieving the above object, the invention provides a kind of power-off brake that is easy to regulate air gap, comprise electromagnet, armature, friction disk and clamping disk; Be provided with spring between electromagnet and the armature, the air gap of 0.2-0.5mm distance is arranged between electromagnet and the armature, the right side of armature is provided with friction disk; Friction disk is between armature and clamping disk; Said power-off brake top is provided with air gap adjustment structure, and said air gap adjustment structure end is provided with lock nut, and said lock nut and clamping disk are near setting; Said clamping disk and stage clip are near setting, and clamping disk is between stage clip and lock nut.
Said air gap is regulated through lock nut.
Adopt stage clip to replace traditional air gap to adjust structural locking nut; Adopt lock nut to replace air gap to adjust structural adjustment nut; Only need directly to regulate air gap adjustment structure with lock nut; Automatically push clamping disk through stage clip, make it, to guarantee between electromagnet and the armature suitable air gap being arranged always near lock nut.
Beneficial effect: the power-off brake that is easy to regulate air gap of the present invention, overcome the shortcoming that existing air gap is adjusted structure, do not need to adjust simultaneously two nuts and guarantee the air gap value, only need lock nut of adjustment to get final product, easy to adjust, quick, accurate.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
