Degree is big, safeguards and changes trouble；The braking of the modes such as hydraulic pressure, magnetic, magnetic hysteresis is with high costs, it is necessary to which external equipment cooperation realization, is needed
Take larger space；There is the shortcomings of security performance requires high in drive and control of electric machine braking, therefore existing brake apparatus is still
Need to further it improve.
Utility model content
The purpose of this utility model be solve the problems of the prior art there is provided one kind it is simple in construction, with low cost, easily
I＆ M, the friction stopping device of quick and easy adjustable braking moment.
To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of friction stopping device, including rotary shaft, in addition to brake unit and fixed cell,
The brake unit is used for brake rotation shaft, and the brake unit includes friction plate, pressing plate and hold-down mechanism；
The pressing plate is fixedly connected with rotary shaft, and the friction plate is arranged between pressing plate and fixed cell, described to compress
Mechanism sets and acted on pressing plate with rotating shaft coaxle；
When hold-down mechanism is in relaxed state, pressing plate and rotary shaft synchronous axial system；
When hold-down mechanism is in impaction state, the surface of pressing plate, friction plate and fixed cell is pressed against one by hold-down mechanism
Act the rotation for preventing rotary shaft.
Further, the hold-down mechanism includes spring and knob, and the knob is installed in rotary shaft, the spring dress
Between knob and pressing plate；The knob is towards during the displacement of pressing plate direction, and spring-compressed simultaneously pushes against pressing plate, pressing plate band movable friction plate
The surface formation for acting on fixed cell compresses friction catch.
Further, the friction plate is fixedly arranged on the surface of fixed cell.
Further, the pressing plate and rotary shaft are removably secured connection.
Further, the pressing plate is connected with rotary shaft by keyway.
Technical scheme described in the utility model is relative to prior art, the beneficial effect of acquirement：
(1) pressing plate with rotary shaft synchronous axial system is set, friction plate is set between pressing plate and fixed cell, passes through compacting machine
The pressing of pressing plate, friction plate and fixed cell is realized in the effect of structure, and the apparatus structure is simple, cost is relatively low, easy I＆ M,
It is manually operated quickly to produce the rotation that high braking moment prevents rotary shaft, without using special tool(s), save manpower thing
Efficiency is improved while power.
(2) hold-down mechanism is set to spring and knob, and mobile knob is compressible spring and pushes against pressing plate band movable friction plate work
Formed used in the surface of fixed cell and compress friction catch, produced braking moment and this braking moment can be adjusted as needed,
The rotary shaft of different rotating speeds is applicable to, using more extensive.
(3) friction plate is fixedly arranged on the surface of fixed cell, and hold-down mechanism need to only promote pressing plate that pressing plate, friction plate can be achieved
With the pressing of fixed cell, the active force for hold-down mechanism is reduced, it is more laborsaving, save the muscle power of operating personnel.
(4) pressing plate is removably secured to be connected with rotary shaft make it that the maintenance of pressing plate and rotary shaft is more convenient.
(5) pressing plate is connected with rotary shaft by keyway, simple in construction, cost-effective.
