Description
Technical field
The present invention relates to a kind of brake, a kind of particularly water-cooled multi-disc friction brake.
Background technology
At present, the technical measures that the controllable braking of domestic and international ribbon conveyer uses are mainly the following：
(1) disc brake apparatus.Mainly it is made of mechanical Pan Zha and controlled hydraulic station, its operation principle is to pass through brake
Friction brake force is applied to scratch diskette and produces braking moment, the size of oil pressure in brake is adjusted by hydraulic station to be adjusted
Normal pressure, so that the size of adjusting brake moment.Hydraulic station employs electro-hydraulic proportional control technology, so the braking of braking system
Torque can be adjusted automatically according to need of work, realize good controllable braking.Shortcoming is that brake disc linear velocity cannot be too
, otherwise easily there is spark in height.
(2) brake fluid system.Hydraulic pump is driven also to produce torque by conveyer system, hydraulic oil pump is to defeated at this time
Send machine to produce an equal amount of damping torque, when damping torque is sufficiently large, conveyer will be braked and realize braking.Hydraulic braking
Two kinds of braking models can be divided into, one kind is pressure regulation braking, and another kind is speed governing braking.Brake fluid system is by controlling oil pressure
Or flow, it can accomplish preferable downward belt conveyor braking deceleration.Due to being in the state that runs at high speed when hydraulic pump is long,
Quick abrasion, short life, in braking procedure, substantial amounts of braking heat is taken away by hydraulic oil, and water cooled radiator heat-dissipation, adds
Set up system；When high oil temperature, hydraulic package easily breaks down, while fluid is due to cycle operation and the temperature change of big flow
Change, it is easy to it is rotten, further influence the reliability of hydraulic control system；At the same time when conveyer determine car, due to hydraulic pump with
The leakage of hydraulic system, it is necessary to specially add push rod band-type brake to be subject to surely automobile-used；Further increase the complexity of system.
(3) hydraulic brake.When the turbine of coupling device is fixed, the high speed liquid flow that pump impeller drives will be produced huge
The moment of resistance, make its deceleration.This is the operation principle of hydraulic-braking system.Hydraulic-braking system is mainly by with pump impeller, turbine
Hydraulic braking coupling device and hydraulic pressure cooling controller composition.The size of braking moment can be changed by adjusting filling amount, it is real
The controllable braking of existing ribbon conveyer.Since pump impeller and turbine are not rigid attachments, the long lifespan of hydraulic braking coupling device.Shortcoming
It is that hydraulic-braking system can not possibly brake conveyer to zero-speed, mechanical brake must be used when pump impeller speed is less than 400r/min
Braking, its same brake fluid system of hydraulic control cooling system, easily breaks down when equally existing high oil temperature or oil difference.
(4) viscous braking device.Once there is the report to " wet multi-disc brake " both at home and abroad, at present wet multi-disc
Brake is more with engineering truck, and the research to " wet multi-disc brake " starts from the U.S..The work of early stage primarily focuses on
Experimental study, the frictional behavior of wet multi-disc brake and clutch is studied by result of the test.In recent years, related wet type is more
Research in terms of a series of basic theories such as pan brake design principle, structure optimization and failure mechanism progressively carrying out and
Constantly improve.The basic functional principle of the present invention is similar to its, but the working characteristics due to ribbon conveyer and engineering truck are not
Together, the design theory of wet multi-disc brake is not properly suited for ribbon conveyer.Foreign countries have no that " liquid glues to ribbon conveyer
Property brake apparatus " research report.

Piece is installed in the cavity by stator internal tooth casing, which is moved by thrust adjustment mechanism with the movable friction plate matches somebody with somebody
Close；The water inlet pipe covers after being arranged on, and is connected by the centre bore in shaft with cavity, and water outlet and oil inlet are respectively provided with
On housing, which communicates with the inside of cavity, the thrust tune that control oil inlet is covered by oil pipe and after being installed on
Complete machine structure communicates.
The thrust adjustment mechanism is at least two groups, covers and is uniformly distributed after, each group of thrust adjustment mechanism
Include disc spring, guide rod, briquetting, piston, screw rod and adjusting nut, the piston is slidably mounted in housing, and described
Oil pipe it is corresponding；One end of guide rod is installed on piston, and the other end is connected with the briquetting, between briquetting and piston
Guide rod periphery is provided with disc spring, and screw rod covers after being installed on, and the outer end of the screw rod is provided with adjusting nut, and the inner is withstood described
Briquetting.
Bearing in shaft is two, is respectively fore bearing and rear bearing, is installed on the housing at fore bearing
Have front bearing retainer, at the rear bearing after cover rear bearing cover be installed.It is an advantage of the invention that：By setting thrust to adjust
Mechanism so that movable friction plate and the direct thrust of static friction piece can adjust, simultaneously because the skidding of kinematics and static friction piece and produce
Heat between friction plate is taken away realization by the cooling water that warp beam centre bore enters and forces cooling by raw heat, improves work
Efficiency, extends the service life of equipment.
