Description
Technical Field
The invention relates to a disc brake type hydraulic coupling.
Background
The coupling is a part for connecting two shafts or a connecting shaft and a rotating part, and rotates together with the shafts without disengaging in the process of transmitting power. The coupler comprises a hydraulic coupler which comprises a thick-walled outer sleeve and a thin-walled inner sleeve which are coaxially inserted and sleeved together; wherein, the inner peripheral surface of the outer sleeve and the outer peripheral surface of the inner sleeve are correspondingly matched with each other with a certain taper. The inner circumferential surface of the outer sleeve is provided with oil grooves which are not communicated with the two ends of the outer sleeve, the side wall of the outer sleeve is provided with an oil port which is communicated with the oil grooves, and the oil port is plugged through bolts. When the hydraulic coupling is installed, the outer sleeve slides to one side with a large diameter of the inner sleeve along the inner sleeve joint conical surface by means of radial and axial oil pressure to force the inner sleeve to contract and the outer sleeve to expand, when the movement displacement of the outer sleeve reaches a designed amount, the bolt is unscrewed to release high-pressure oil, at the moment, the inner sleeve is in interference fit with the outer sleeve, positive pressure exists between interference fit surfaces, and torque is transmitted by friction force generated by the positive pressure during working.
When the hydraulic coupling in the prior art is in a working state of high-speed operation, a large rotational inertia can be generated, and a conventional bolt type brake device in the prior art can cause slow braking or the risk of bolt breakage, so that the use requirement can not be effectively met.

Detailed Description
The present invention will be described in further detail with reference to examples and specific embodiments.
As shown in fig. 1, the disc brake type hydraulic coupling structurally comprises an inner sleeve 1, an outer sleeve 2, a brake disc 4 and a piston 6, wherein the outer peripheral surface of the inner sleeve 1 is connected with the inner peripheral surface of the outer sleeve 2, the piston 6 is arranged at one end of the outer sleeve 2, and the butterfly type brake disc 4 is assembled at one end of the outer sleeve 2 where the piston 6 is located.
The brake disc 4 is connected with one end of the outer sleeve 2 in a threaded mode and is fixed through a threaded pin 5.
The outer peripheral face of the inner sleeve 1 and the inner peripheral face of the outer sleeve 2 are connected through conical surfaces which are correspondingly arranged and matched with each other and provided with tapers, a piston 6 is arranged in a stepped piston cavity at one end with the smaller inner diameter of the outer sleeve 2, the piston 6 is connected with the inner sleeve 1 through threads, a sealing ring 9 is arranged at the inner side end of the piston 6 (the stepped piston cavity forms a sealed cavity), oil ports communicated with the piston cavity are formed in the side wall of the outer sleeve 2, thread-shaped oil grooves are formed in the terminal of the inner peripheral face of the outer sleeve 2, oil ports communicated with the oil grooves are formed in the side wall of the outer sleeve 2 in a penetrating mode, two oil ports are respectively internally connected with the blind screws 3, and the two opposite ends of the blind screws 3 are pressed to be pressed (interlocking is achieved).
The top end of the blind screw 3 is positioned inside the oil port. There is no protruding member on the outer peripheral surface of the outer jacket 2.
The outer side of the piston 6 is provided with a pressing plate 8, the pressing plate 8 is pressed on the outer end face of the piston 6, and the pressing plate 8 is fixed on the outer sleeve 2 through a pressing plate bolt 7.
According to the structure, when the shafting runs at a high speed, the brake device slowly shrinks to work in a manner similar to an automobile disc brake, so that the deformation and the deadlocking of the plug pin of the brake disc or the too slow brake caused by too high rotating speed and too large rotational inertia of the shafting can be effectively prevented. Meanwhile, the disc brake type brake disc can be used for a long time, so that the cost is reduced, and the maintenance frequency caused by faults such as dead locking due to deformation of a brake disc bolt and damage of the brake disc can be effectively reduced.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
