Description
Technical field
The utility model relates to a kind of frequency control AC brake threephase asynchronous.
Background technology
Frequency control AC brake threephase asynchronous is made up of YP series frequency converting speed regulating three-phase asynchronous electromotor, three-phase alternating current brake and cooling blower.The high-frequency impulse that variable frequency power supply produces and high order harmonic component on motor and the impact of brake winding very large, therefore on the insulation system of motor and brake, adopt special counter-measure; Braking motor can be widely used in the industries such as light industry, weaving, machine driving, plating production line, and all requirements need speed governing, the equipment of fast braking, accurately location is all applicable to using YPEJU series braking motor.
Summary of the invention
The technical problems to be solved in the utility model is to provide the frequency control AC brake threephase asynchronous that a kind of structure simply reduces labor strength.
For solving the problem, the utility model adopts following technical scheme:
A kind of frequency control AC brake threephase asynchronous, comprise shell, rotating shaft, support, maintenance window, screw rod, armature card, tripping spring, lock nut I, nut, yoke, lock nut II, cooling blower and hand release, described outer casing bottom is provided with support, described shell is connected with rotating shaft by bearing, described rotating shaft is provided with armature card and yoke, described armature card and yoke to be cooperatively interacted with the rear end cap being arranged on enclosure by screw rod and are connected, gap is provided with between described armature card and yoke, described inner space is provided with tripping spring, described rotating shaft end head is connected with cooling blower, described screw rod is respectively arranged with lock nut I and lock nut II at yoke two ends, hand release is connected with above described shell.
As preferably, described shell is provided with maintenance window.
As preferably, described screw rod is equipped with nut.
The utility model structure is simple, easy to operate, more economizes the energy; Environmental protection, life-span length, maintenance are simply; Brake changes by direct current supply the advanced ac brake that three phase mains directly powers into, without the need to switching electronic element, improves reliability of operation greatly; It is fast that ac brake has starting-up response, and braking time is short, accurate positioning, the advantages such as long service life.
accompanying drawing illustrates:
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings;
Fig. 1 is structural representation of the present utility model;
embodiment:
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Consult shown in Fig. 1, a kind of frequency control AC brake threephase asynchronous, comprise shell 1, rotating shaft 2, support 3, maintenance window 4, screw rod 5, armature card 6, tripping spring 7, lock nut I 8, nut 9, yoke 10, lock nut II 11, cooling blower 12 and hand release 13, support 3 is provided with bottom described shell 1, described shell 1 is connected with rotating shaft 2 by bearing, described rotating shaft 2 is provided with armature card 6 and yoke 10, described armature card 6 and yoke 10 to be cooperatively interacted with the rear end cap being arranged on shell 1 inside by screw rod 5 and are connected, gap is provided with between described armature card 6 and yoke 10, described inner space is provided with tripping spring 7, described rotating shaft 2 termination is connected with cooling blower 12, described screw rod 5 is respectively arranged with lock nut I 8 and lock nut II 11 at yoke 10 two ends, hand release 13 is connected with above described shell 1, described support 3 is provided with damping device.
It should be noted that and described shell 1 is provided with maintenance window 4.
It should be noted that and described screw rod 5 is equipped with nut 9.
During the utility model Motor Production Test, all adjusted is to standard value for moment, and after motor uses a period of time, after friction disc wear, tripping spring is slightly relaxed, and braking moment relatively slightly declines, and does not have large impact as used, can be motionless.As felt, moment declines to some extent, when need increase braking moment, and can by even for three lock nuts 4 precession about 180 ° about half-turn forward, maximum one circle, can not be too many, due to braking moment too conference cause adhesive difficulty, or sending unpleasant to hear electromagnetic sound, serious meeting burns out coil.If braking moment need be reduced, then lock nut 4 is unscrewed 180 ° of half-turns backward, a maximum circle, otherwise moment is too little.No matter moment is turned down or tuned up all will be readjusted gap.
The standardized element that the utility model uses all can be commercially, shaped piece all can carry out customized according to specification with the record of accompanying drawing, the concrete connected mode of each part all adopts the conventional means such as bolt, rivet, welding ripe in prior art, machinery, part and equipment all adopt in prior art, conventional model, add that circuit connects and adopt connected mode conventional in prior art, be not described in detail in this.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present 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.
