Description
Technical Field
The invention belongs to the technical field of transmission of designed fluid machinery, and particularly relates to a coupler.
Background
In the fluid mechanical transmission, in order to connect the driving shaft and the driven fluid path together, a fluid path rotary joint is generally required to be provided at the joint, and in order to connect the fluid path rotary joint and the driving shaft together, a connecting member having a coupling function is required to be used, thereby realizing efficient transmission between the two. Meanwhile, the connecting piece can effectively avoid the occurrence of factors unfavorable for transmission, such as axial deviation, radial deviation, angle deviation and the like during transmission.
On the other hand, for the purpose of protecting the fluid path, the drive shaft is sometimes required to be a hollow drive shaft, and the fluid path system is hidden in the drive shaft so as to be protected from the environment and other parts. In this case, special constructional requirements are imposed on the connecting elements used.
The structure of the rotor port of the liquid path rotary joint is different from the structure of the two ends of a common transmission device, and the liquid path rotary joint cannot be connected with a main shaft through a common coupler. It is often designed with an irregular shape of a hexagonal prism combined cylinder and interface. The connector must match its dimensional characteristics. If the rotor port of the liquid path rotary joint is directly connected with the main transmission shaft, the internal shape of the main transmission shaft is limited, and the processing difficulty of the internal space of the main transmission shaft is increased.
