Problems solved by technology
The conventional seal assembly is used to form an oil chamber between the inner sleeve and the outer sleeve, but the sealing structure is complex and the reliability in operation is low. The reason for using the seal assembly is that the inner sleeve and the outer sleeve of the coupling sleeve are thinner, which cannot overcome the welding process. The deformation caused by

Embodiment
[0038] The processing technology of the coupling sleeve of the hydraulic safety coupling of the present invention, the coupling and the installation structure are as follows: figure 1 As shown, it includes a coupling sleeve, a driving shaft 9 located inside the coupling sleeve and a user mechanism 10 located outside the coupling sleeve. The coupling sleeve includes an inner sleeve 1 and an outer sleeve 2. The inner sleeve 1 and the outer sleeve 2 are assembled into one body and formed between The oil chamber 3 and the jacket 2 are provided with a shear pipe hole 4 and an oil inlet hole 5 connected to the oil chamber 3. The working process is as follows: the high-pressure oil enters the oil chamber 3 through the oil inlet hole 5, and the shear pipe hole is used to The shearing tube 7 inside 4 realizes the locking of oil pressure, and under the action of oil pressure, the inner sleeve 1 and the outer sleeve 2 hold the driving shaft 9 inwardly and the user mechanism 10 outwardly, ...

Abstract
The invention discloses a machining process for a hydraulic safety coupling connection sleeve, and belongs to the technical field of coupling machining. The machining process for the coupling connection sleeve includes the following steps that A, an inner sleeve and an outer sleeve are independently machined, machining allowance is reserved for both the inner side face of the inner sleeve and the outer side face of the outer sleeve, and a radial through gas hole is machined in the position, corresponding to an oil cavity, on the outer sleeve; B, the inner sleeve is assembled in the outer sleeve, and the inner sleeve and the outer sleeve are welded from the two end portions so that the inner sleeve and the outer sleeve can be assembled to form a whole structure with the oil cavity; C, the gas hole is blocked; D, a shearing pipe hole and an oil inlet hole are machined on the outer sleeve; and E, fine machining of the inner side face and the outer side face are conducted on the inner sleeve and the outer sleeve which are welded into a whole, and therefore the deformation amount in the welding process is eliminated, and the concentricity of the inner side face and the outer side face is ensured. According to the machining process, assembling of the inner sleeve and the outer sleeve is achieved through welding, the structure is simple, machining is rapid, and the high-precision connection sleeve is easily obtained, and a coupling manufactured through the process has the beneficial effect of being high in structure reliability.
Description
technical field [0001] The invention relates to a processing technology of a shaft coupling, in particular to a processing technology of a coupling sleeve of a hydraulic safety coupling, and belongs to the technical field of shaft coupling processing. Background technique [0002] With the development of technology, more and more attention is paid to the application of new couplings, and higher requirements are put forward for safety, durability and reliability. As a new type of coupling, hydraulic safety coupling has the advantages of compact structure, light weight, small moment of inertia and easy assembly. It can also be used in combination with other transmission components, such as drum gear coupling, cross shaft universal Couplings, flexible couplings, gears and shafts, etc., can realize the functions of coupling, fixing, torque transmission and overload safety protection. Therefore, the hydraulic safety coupling has great practical value and practical significance i...
