Centrifugal flow guiding intelligent speed governing hydraulic coupler body structure

Abstract

The utility model relates to a body structure of a centrifugal diversion intelligent speed-regulating hydraulic coupling, which belongs to the technical fields of energy saving and hydraulic transmission. Including pump wheel, pump wheel flange, turbine, driving shaft, driven shaft, box body, oil inlet and outlet connecting pipes, speed sensor, speed measuring gear, rotary casing, rotary casing flange, nozzle, left and right sealing end faces, oil sealing ring , the present invention adopts the principle of centrifugal flow diversion. Under the action of centrifugal force, the nozzle installed on the rotary shell is used to draw out the working oil for cooling, and the number and aperture of the nozzle are determined according to the coupling model and load characteristics, and the coupling is more adaptable to the load. ;The radially arranged labyrinth oil seal greatly reduces the leakage at the seal, reduces the energy loss of the coupler, and enhances the controllability of the coupler's speed and working stability; the coupler adopts an external support method, and the box no longer bears the weight of the coupler body , it only plays the role of oil storage, its wall thickness and size are significantly reduced, the overall structure of the coupling is more compact, saving raw materials, and has significant economic and social benefits.

Description

technical field [0001] The invention relates to a speed-regulating hydraulic coupling, in particular to a body structure of a coupling body that adopts a labyrinth oil seal and a centrifugal flow diversion intelligent speed-regulating hydraulic coupling that extracts working oil from a nozzle, which belongs to energy-saving and hydraulic transmission. technology field. Background technique [0002] At present, there are many traditional speed-regulating hydraulic couplings, and their common feature is that a certain amount of working oil is filled in the working chamber of the hydraulic coupling, and the pump wheel obtains mechanical energy from the prime mover, converts it into liquid energy, flows to the turbine and Make it rotate, the turbine converts the liquid energy into mechanical energy output, and repeats itself, realizing the energy transfer from the prime mover to the working machine. Usually, the speed regulation of the speed-regulating hydraulic coupling is rea...

Problems solved by technology

The labyrinth oil seal of the coupler body structure is arranged along the axial direction of the coupler, and the centrifugal force of the working oil rotation cannot be utilized, resulting in large oil leakage, resulting in energy loss and instability of the coupler work; its working oil It is led out from the trumpet-shaped openings with a fixed number and diameter on the rotary housing. The energy of the drawn-out working oil is not fully utilized, and at the same time, the adaptability of the coupler to the load is reduced; the coupler body adopts an internal support method. In order to ensure strength, The structural size of the coupler box is relatively large
