Abstract
The utility model provides a kind of without rotor electromagnetic power-off brake, relate to automated execution member arts, comprise the break yoke be arranged on main shaft, break armature, motor ventilating fan, it is characterized in that: described break yoke and back end cover for motor coenosarc, between described break armature side and break yoke, brake spring is set, described break armature opposite side is bonded with friction plate, and the front-end face car of described motor ventilating fan becomes plane, contacts with friction plate as friction pair.Break yoke and back end cover for motor combine by the utility model, save back end cover for motor, effectively can shorten the length of motor, reduce the cost of braking motor; Cancel common brake rotor, be bonded in by friction plate on break armature, and use flat for motor ventilating fan front-end face car as friction pair, during braking, fan is compressed by break armature, friction plate by brake spring, thus reaches the effect of braking.
Description
Technical field
The utility model relates to automated execution member arts, particularly relates to a kind of without rotor electromagnetic power-off brake.
Background technique
Electromagnetic brake is a kind of connector master end torsion being conveyed to passive side, can combine freely according to needs, cut off or brake, start is carried out because using electromagnetic force, be referred to as magnetic clutch, break, electromagnetic brake is a kind of desirable automated execution element in modern industry, in machine driven system, mainly play the effect such as transferring power and controlled motion.Have compact structure, simple to operate, respond sensitive, the life-span is permanent, uses reliable, is easy to realize the advantages such as distant control.
Traditional electromagnetism dead electricity braking, primarily of compositions such as yoke, armature, brake disc (rotor), geared sleeves, when the vertical installation of motor, rotates owing to there being rotor and moves, can produce noise.Existing electromagnetic brake is not suitable with the occasion of vertical installation.Also there is structural design not compact, the defect that volume is larger.
Model utility content
The purpose of this utility model is to provide a kind of without rotor electromagnetic power-off brake, to solve the problems of the technologies described above.For the occasion making electromagnetic brake adapt to vertical installation, by carrying out technological improvement to traditional electromagnetic power-off brake, a kind of electromagnetic power-off brake without rotor is provided, and break yoke and back end cover for motor are combined, the common break of effective solution affects problem by setting angle, also greatly reduces weight and the cost of braking motor.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of without rotor electromagnetic power-off brake, comprise the break yoke be arranged on main shaft, break armature, motor ventilating fan, it is characterized in that: described break yoke and back end cover for motor coenosarc, between described break armature side and break yoke, brake spring is set, described break armature opposite side is bonded with friction plate, the front-end face car of described motor ventilating fan becomes plane, contacts with friction plate as friction pair.
Described break yoke is arranged on main shaft by bearing, and the main shaft of bearing and motor ventilating fan overlaps preloading spring.
During dead electricity, break armature is ejected under brake spring effect, and friction plate is contacted with the friction pair of motor ventilating fan, realizes dead electricity braking; During energising, break armature is attracted to break yoke, and friction plate is separated with the friction pair of motor ventilating fan.
The beneficial effects of the utility model are:
Break yoke and back end cover for motor combine by the utility model, save back end cover for motor, effectively can shorten the length of motor, reduce the cost of braking motor; Cancel common brake rotor, be bonded in by friction plate on break armature, and use flat for motor ventilating fan front-end face car as friction pair, during braking, fan is compressed by break armature, friction plate by brake spring, thus reaches the effect of braking.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in mode of execution, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
As shown in Figure 1, a kind of without rotor electromagnetic power-off brake, comprise the break yoke 3 be arranged on main shaft 1, break armature 5, motor ventilating fan 6, break yoke 3 and back end cover for motor coenosarc, brake spring 4 is set between break armature 5 side and break yoke 3, break armature 5 opposite side is bonded with friction plate 7, and the front-end face car of motor ventilating fan 6 becomes plane, contacts with friction plate 7 as friction pair; Break yoke 3 is arranged on main shaft 1 by bearing 8, and the main shaft 1 of bearing 8 and motor ventilating fan 6 overlaps preloading spring 2.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification is only preference of the present utility model; be not used for limiting the utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. one kind without rotor electromagnetic power-off brake, comprise the break yoke be arranged on main shaft, break armature, motor ventilating fan, it is characterized in that: described break yoke and back end cover for motor coenosarc, between described break armature side and break yoke, brake spring is set, described break armature opposite side is bonded with friction plate, the front-end face car of described motor ventilating fan becomes plane, contacts with friction plate as friction pair.
2. according to claim 1 without rotor electromagnetic power-off brake, it is characterized in that: described break yoke is arranged on main shaft by bearing, the main shaft of bearing and motor ventilating fan overlaps preloading spring.
