Description
Technical Field
The invention relates to a hydraulic coupler with a quickly adjustable overall length, and belongs to the technical field of hydraulic transmission equipment.
Background
The hydraulic coupler is also called as a hydraulic coupling, and is a universal hydraulic transmission element with wide application. It is placed between power machine (motor) and working machine to transfer power. The characteristic of the hydraulic coupler can be divided into three basic types, namely a common type, a torque-limiting type and a speed-regulating type, and the typical torque-limiting type hydraulic coupler structure consists of components such as an impeller, a shell, a turbine, a rear auxiliary chamber, a main shaft, a brake wheel and the like which are symmetrically arranged. The early hydraulic coupler is mostly an imported part, but with the continuous development of modern industrial technology in China, the imported hydraulic coupler is gradually replaced by domestic technology. Because of different design concepts and technical capacities, in order to ensure that the rotation moment is generally larger and longer, in domestic replacement, the whole driving mechanism must be adjusted in order to ensure normal installation, and a common adjusting scheme is to move the driving motor backwards, so that larger workload is caused. Therefore, how to design a fluid coupling with a length capable of being conveniently adjusted without changing a driving mechanism becomes a problem to be solved.
Disclosure of Invention
The invention aims to solve the technical problem of designing a length-adjustable hydraulic coupler, and the length of the hydraulic coupler can be adjusted by self-assembly data on the basis of ensuring sufficient rotation moment, so that the aim of replacing various types of imported hydraulic couplers by using a domestic hydraulic coupler without adjusting an integral driving structure is fulfilled.
The technical scheme for solving the technical problems is as follows:
The utility model provides a but overall length swiftly adjusts fluid coupling, it includes brake pulley, quincuncial elastic block, male coupling, back assist chamber, fluid coupling main part, and the speed reducer of drive structure is connected to brake pulley one end, and one end is in the same place through quincuncial elastic block, male coupling and back assist chamber connection, and male coupling is half to be fixed in on the brake pulley, and half is fixed in on the back assist chamber shell, and back abdominal cavity is connected with fluid coupling.
The fluid coupling with the overall length capable of being quickly adjusted is a relatively mature product of the current domestic technology, and is not described in detail herein.
The hydraulic coupler with the overall length capable of being quickly adjusted is characterized in that the diameter of the brake wheel is larger than that of the rear auxiliary cavity, and the rear auxiliary cavity can be nested into the brake wheel after the brake wheel and the inserted coupling of the rear auxiliary cavity are mutually inserted.
The size of the inserted coupling insertion block of the brake wheel and the rear auxiliary cavity is larger than that of a common insertion block, the width and the length are designed with redundancy, and the depth of the mutual insertion changes to enable the depth of the rear auxiliary cavity sleeved into the brake wheel to change along with the depth of the mutual insertion, so that the adjustment of the whole length of the hydraulic coupler is realized.
The overall length of the hydraulic coupler can be quickly adjusted, and the length of the rear auxiliary cavity is increased due to the reduction of the diameter, so that the sufficient moment of the hydraulic coupler is ensured.
The beneficial effects of the invention are as follows:
According to the invention, the rear auxiliary cavity of the hydraulic coupler is nested into the brake wheel, the size redundancy design of the plug-in coupling plug-in blocks of the brake wheel and the rear auxiliary cavity is adopted, and the adjustment of the whole length of the hydraulic coupler is realized by adjusting the plug-in depth of the plug-in blocks, so that a domestic hydraulic coupler can directly replace various imported hydraulic couplers of different types, and the problem of large domestic workload of the hydraulic coupler is solved. Under the condition that the main structure of the hydraulic coupler is not changed, the invention realizes the direct replacement work of the domestic hydraulic coupler through reasonable layout, saves the investment for modifying dust removing equipment and improves the maintenance efficiency of the original integral driving mechanism. The novel hydraulic coupler has the advantages of simple structure, reasonable design, convenient installation, disassembly and maintenance, and is suitable for localization of imported hydraulic couplers.
