Abstract
The utility model discloses a power-off brake with an easily adjusted air gap. The power-off brake comprises an electromagnet, an armature, a friction disk and a clamping disk, a spring is arranged between the electromagnet and the armature, the air gap with the distance of 0.2-0.5mm is formed between the electromagnet and the armature, the friction disk is arranged on the right side of the armature and located between the armature and the clamping disk, an air gap adjusting structure is arranged at the top end of the power-off brake, a lock nut is arranged at the tail end of the air gap adjusting structure and adjoined to the clamping disk, the clamping disk is adjoined to a pressure spring, and the clamping disk is located between the pressure spring and the lock nut. According to the power-off brake with the easily adjusted air gap, defects of existing air gap adjusting structures are overcome, and only one lock nut is required to be adjusted to guarantee an air gap value instead of two nuts, so that the adjustment is convenient, fast and accurate.
Description
Technical field
The utility model relates to the break field, is specifically related to a kind of power-off brake that is easy to regulate air gap.
Background technique
Traditional power-off brake is comprised 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 after adjusting by the adjustment piece nut, lock with locking nut again, after adjusting nut is adjusted to suitable location, during locking nut locking, air gap can change, that is, suitable air gap value must lean on adjusting nut and two parts of locking nut jointly to finish, and the difficulty of adjustment is large, requirement is high, precision is low, efficient is low.
The model utility content
The model utility purpose: the purpose of this utility model is in order to address 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 utility model 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 that the 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, described power-off brake top is provided with air gap and adjusts structure, described air gap is adjusted the structure end and is provided with lock nut, described lock nut and clamping disk are near setting, and described clamping disk and stage clip are near setting, and clamping disk is between stage clip and lock nut.
Described air gap is regulated by 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 adjusting nut, only need directly to regulate air gap with lock nut and adjust structure, automatically push clamping disk by stage clip, make it always near lock nut, to guarantee between electromagnet and the armature suitable air gap being arranged.
Beneficial effect: the power-off brake that is easy to regulate air gap of the present utility model, 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 to adjust a lock nut and get final product, easy to adjust, quick, accurate.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
A kind of power-off brake that is easy to regulate air gap as shown in drawings, comprise electromagnet 1, armature 2, friction disk 3 and clamping disk 4, be provided with spring between electromagnet 1 and the armature 2, the air gap that the 0.2-0.5mm distance is arranged between electromagnet 1 and the armature 2, the right side of armature 2 is provided with friction disk 3, friction disk 3 is between armature 2 and clamping disk 4, described power-off brake top is provided with air gap and adjusts structure 7, described air gap is adjusted structure 7 ends and is provided with lock nut 6, described lock nut 6 and clamping disk 4 are near setting, described clamping disk 4 and stage clip 5 are near setting, and clamping disk 4 is between stage clip 5 and lock nut 6, and described air gap is regulated by lock nut 6.
