The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a friction type braking device comprises a round cover 2, a spring 3, a piston 4, a gasket 5, a cylinder 6, an outer shell 7, an outer friction plate 8, an inner friction plate 9, a spline sleeve 10 and a screw rod 11; the shell 7 is fixedly connected with the cylinder body 6, the round cover 2, the cylinder body 6 and the shell 7 are fixedly connected and fixed on the box body through a screw rod 11, and the screw plug 1 is arranged in the middle of the round cover 2; a piston 4 is arranged in the cylinder body 6, an oil cavity 13 is arranged between the cylinder body 6 and the piston 4, and the piston 4 can axially move under the action of pressure oil; a round cover 2 is arranged at the outer end of the cylinder body 6, a spring 3 is arranged between the round cover 2 and the piston 4, and the spring 3 is a belleville spring; an outer friction plate 8, an inner friction plate 9 and a spline housing 10 are arranged in the outer shell 7, the inner friction plate 9 is connected with the spline housing 10 through an inner spline, and the outer friction plate 8 is connected with the outer shell 7 through an outer spline; the inner end of the piston 4 bears against the outer friction plate 8.
The two sides of the spring 3 are provided with gaskets 5, the thickness of each gasket 5 is 1-5mm, the gaskets 5 can be replaced, and the pressure values of the inner friction plate and the outer friction plate of the piston 4 can be adjusted by adjusting the thickness of each gasket 5.
An oil inlet and outlet 12 is arranged on the cylinder body 6, and the oil inlet and outlet 12 is connected with an oil cavity 13.
The diameters of the outer friction plate 8 and the inner friction plate 9 are the same, the diameter is 200-500mm, and the braking resistance is set by adopting the friction plates with different diameters.
The working process is as follows: the inner friction plate 9 is connected with the spline housing 10 through an inner spline, and the inner spline of the spline housing 10 is connected with the transmission mechanism and can rotate. The outer friction plate 8 is fixedly connected with the outer shell 7 through an outer spline, and the outer shell 7 and the cylinder body 6 are fixed with the box body through a screw rod 11. An oil chamber 13 is formed between the piston 4 and the cylinder block 6 and is axially movable by the pressure oil. The disc spring 3 is in compression between the piston 4 and the dome 2. One end of the piston is pressed against the outer friction plate 8, so that the outer friction plate 8 and the inner friction plate 9 are in a friction braking state, and the pressure value can be adjusted through the gasket 5. During operation, pressure oil enters the oil cavity 13 to push the piston 4 to move axially, the spring 3 is further compressed, and the force applied to the outer friction plate 8 by one end of the piston 4 is reduced, so that the outer friction plate 8 and the inner friction plate 9 are in a non-braking state. Once braking is needed, the pressure oil loses pressure, the spring 3 is tensioned, and the inner friction plate 8 and the outer friction plate 9 are tensioned for braking. When the device is not required to be braked, the screw plug 1 can be detached, and the piston 4 is pulled out by a bolt, so that the outer friction plate 8 and the outer friction plate 9 are always in a non-friction state.
