Ultra-light multifunctional hydraulic coupling outer sleeve structure

Technical Field

The utility model relates to an ultra-light multifunctional hydraulic coupling outer sleeve structure.

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 end surfaces 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 by 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, certain vibration can be generated, and noise is generated due to the vibration. And under the condition that the end face of the flange is a straight face, the transmission torque of the coupler cannot be increased, so that the requirement of the market on the coupler is limited to a certain extent, and the use requirement cannot be effectively met.

SUMMERY OF THE UTILITY MODEL

The utility model provides an ultra-light multifunctional hydraulic coupling outer sleeve structure, which aims to overcome the defects in the prior art, save a piston cavity and avoid vibration and noise.

The technical solution of the utility model is as follows: the utility model provides an ultralight multi-functional hydraulic coupling overcoat structure, its structure includes the overcoat body, and overcoat body inner peripheral surface is the conical surface that the whole has the tapering, and it has a plurality of inlet port to have link up to open axially on the overcoat body, and overcoat body both ends face all is the kuppe connection face respectively.

Preferably, the surface of the connecting surface of the air guide sleeve is in a sawtooth thread shape.

The utility model has the advantages that: the hydraulic coupling outer sleeve is reasonable in structural design, a piston cavity structure of a conventional coupling can be omitted, the rotational inertia of the coupling during driving or braking can be effectively reduced under the working state of high-speed operation of the assembled coupling, the whole self weight of the coupling is reduced, and vibration, abnormal sound and potential safety hazards caused by pistons and accessories of the pistons can be avoided.
