Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
as can be seen from fig. 1, the present utility model includes: a rotating assembly; the rotating assembly includes: the clutch comprises a clutch seat 13, a spring support disc 7, an O-shaped ring 4, a first screw set 5, a cylindrical pin set 3, a spring 8, a piston 1, a first sealing ring 2, a second sealing ring 6, a pair of plates 10, a wave spring 14, a rear end flange 11 and a second screw set 12; the O-shaped ring 4 and the first sealing ring 2 are arranged on the clutch seat 13; the second sealing ring 6 is arranged on the piston 1; the piston 1 is connected to the clutch seat 13 through a spline and moves relatively axially; the spring 8 is arranged in the piston 1, one end of the spring is propped against the piston 1, and the other end of the spring is propped against the spring supporting disc 7; the spring support disc 7 is connected to the clutch seat 13 through the first screw group 5 and the cylindrical pin group 3; the dual-disc 10 is connected to the clutch base 13 through a spline and moves relatively axially; the wave spring 14 is arranged between the two pairs of coupling pieces 10; the rear end flange 11 is connected to the clutch seat 13 through a second screw set 12; further comprises: a transmission assembly; the transmission assembly includes: an inner gear ring 15 and a friction plate 9; the friction plate 9 is connected to the annular gear 15 through a spline and moves axially relatively; the pair of plates 10 and the friction plate 9 form a clutch friction group, and torque transmission is provided when the clutch friction group is pressed.
The rotating component is connected with a driving piece of the mechanical equipment;

The working principle of the utility model is as follows: when the transmission part stops, hydraulic oil from the outside enters a sealing cavity formed by the clutch seat 13, the piston 1, the O-shaped ring 4, the first sealing ring 2 and the second sealing ring 6 through the oil inlet A, the piston 1 is pushed to move rightwards, the spring 8 moves rightwards, the dual-plate 10 and the friction plate 9 are separated, and the transmission part stops working rapidly. When the transmission part is required to work, hydraulic oil in a sealing cavity formed by the clutch seat 13, the piston 1, the O-shaped ring 4, the first sealing ring 2 and the second sealing ring 6 is rapidly discharged from the rapid oil inlet A, and the spring 8 pushes the piston 1 to move leftwards, so that the dual-plate 10 and the friction plate 9 are engaged to transmit torque, and the transmission part is driven to work.
The utility model also reserves 3 emergency release screws B and 24 emergency joint screws C. The function of installing the emergency release screw at the position 3 is that when the hydraulic system fails, 3 emergency release screws can be installed to pull the piston, so that the hydraulic dry normally-closed clutch is released, and the normal operation of mechanical equipment is ensured. The emergency joint screw is installed at the position 24, so that when the spring of the hydraulic dry normally-closed clutch fails to be damaged, the rotating assembly and the transmission assembly can be fixed by the emergency joint screw, and the mechanical equipment can work normally. Because of the characteristics of the hydraulic dry normally-closed clutch, the utilization rate of equipment can be greatly improved, the later maintenance cost of products is reduced, and the hydraulic dry normally-closed clutch has wide popularization and application prospects.
