Disc brake is the hydraulic actuator applied in mine hoist brake
system, mainly used for JTP single cylinder 1.2m, 1.6m, 2m, 2.5m,
3M mine hoist brake device. In the elevator when starting the
hydraulic station output pressure oil on the brakes, lifting
machine to work, work brake, hydraulic station according to the
condition of increasing or decreasing pressure, brake will provide
braking force on the contrary, in the case of accidents, the
hydraulic pressure station to residual pressure, actuator with
maximum braking force in the shortest time to hoist parking
The lifting mechanism has two main types
The disc brake is produced by the disc spring, and the brake is
pressed by the hydraulic pressure. When the braking state is used,
the spring force of the disc spring group is used for the brake.
When the oil pressure is reduced to zero (the gate process), the
spring force generated by the compact disc spring pre mid shaft and
disc spring push studs to the brake shoe wear compensation effect,
positive spring force is applied the brake shoe and the brake disc
brake is attached to pressure, thereby restricting the brake disc
rotation trend. The cylinder pressure chamber filled with oil
(boost brake process), when the oil pressure is gradually increased
to the working pressure, the piston and the brake shoe connected by
oil pressure, overcome the pretightening force of disc spring and
spring compression caused the rearward displacement of piston,
through a large hollow stud, drive shaft, brake disc spring set
wear compensation stud and drives the brake shoe after the shift, a
gap is formed between the brake shoe and the brake disc, thereby
lifting the braking effect on the positive pressure of the brake
disc
Technical parameters:
The advantages of the rear cylinder disc brake are: compact structure, small size, adjustable performance, sensitive action, light weight, small inertia, high safety, good versatility and so on. When used in pairs, the main shaft does not bear the additional axial force, but also can be used in classification |
