A semi-hydraulic coupler

Abstract

The invention discloses a half hydraulic coupler. The half hydraulic coupler comprises an outer shell, an input shaft, an output shaft, an outer rotor and an inner rotor, wherein the outer end of the input shaft and the outer end of the output shaft extend outside the outer shell, the outer rotor is installed in the outer shell and fixedly connected with the output shaft, and the inner rotor is sleeved with the outer rotor and fixedly connected with the input shaft; the inner wall of the outer rotor is a round reducing hook face which is equally divided into a plurality of equally-divided hook face bodies, the reducing size and the direction of the equally-divided hook face bodies are the same, a plurality of movable tooth grooves are formed in the outer wall of the inner rotor, movable teeth are embedded into the corresponding movable tooth grooves in a one-to-one manner, the bottoms of the movable tooth grooves are communicated with a high-pressure oil inlet, and outer ends of the movable teeth face the hook face of the outer rotor. The half hydraulic coupler has the beneficial effects of being wide in speed regulating scope, high in efficiency, small in size and small in weight; the rotating-speed difference is avoided during full-power output power, and meanwhile the soft starting function and outer load impact isolation performance are achieved; as the working efficiency of the half hydraulic coupler is high, the heating amount during working is less, and the half hydraulic coupler has the beneficial effect of being small in number of additional device, high in reliability, low in cost and the like.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a semi-hydraulic coupler which can amplify the input torque, has high efficiency, and has a large speed ratio variation range in addition to the basic characteristics of the hydraulic coupler. Background technique [0002] The hydraulic coupling currently used has the function of stepless speed regulation, which can realize no-load start-up and overload protection functions, realize the soft connection between the power source and the load, can isolate the impact of load vibration on the power source, and can power the power source when the load fails. It is not damaged, and it is a good solution to the needs of some industrial sites. [0003] The shortcomings of the hydraulic coupling as a speed regulating device are mainly manifested in the narrow speed regulating range and low mechanical efficiency; in addition, the hydraulic coupling uses hydraulic power to transmit pow...
