Description
Technical Field
The utility model relates to an hub connection technical field specifically is a big moment of torsion hydraulic coupling of vibration/noise reduction type.
Background
The coupling is a part for connecting the two shafts or the connecting shaft and the rotating part and rotates together with the shafts without disengaging in the process of transmitting power. The hydraulic coupler comprises a thick-wall outer sleeve and a thin-wall inner sleeve which are coaxially inserted and sleeved together, wherein the inner circumferential surface of the outer sleeve and the outer circumferential surface of the inner sleeve are correspondingly matched with each other in 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 coupler is in a working state of high-speed operation, certain vibration can be generated, noise is generated due to the vibration, and when the torque is large, the existing coupler cannot well transmit the torque, so that the requirement of the coupler on the market is limited to a certain extent.
Disclosure of Invention
In order to solve the big problem of noise among the big moment of torsion difficulty of current shaft coupling transmission and the high-speed operation, the utility model provides a big moment of torsion hydraulic coupling of vibration/noise reduction type, it can transmit big moment of torsion when solving vibration/noise reduction.
The technical scheme is as follows: the damping and noise-reducing type high-torque hydraulic coupler is characterized in that a flange connecting surface is arranged at one end of the outer sleeve, the end face of the flange connecting surface is a corrugated surface, a connecting hole is formed in the flange connecting surface, and a rubber ring is sleeved in the connecting hole.
The piston is further characterized in that a step piston cavity is arranged at one end of the outer sleeve with a small inner hole diameter, a piston is arranged at the step piston cavity, and a sealing ring is arranged on the inner side surface of the piston;
the oil inlet hole is internally provided with a countersunk head plug screw.
Adopt the utility model discloses afterwards, increase the rubber circle at the connecting hole position of shaft coupling, thereby the rubber circle can absorbed vibration, can be in high-speed moving operating condition at the shaft coupling and reach vibration/noise reduction's effect, and the curved surface contact is made to the flange terminal surface simultaneously, and is more to traditional straight face contact, and the curved surface contact is increasing the transmission moment of torsion of shaft coupling.
