Problems solved by technology
[0003] The output shaft of the steam turbine has a large torque. If the general coupling only plays the role of connecting two shafts, it will generally bear too much load and cause the life of the coupling itself to be short. Once the coupling is damaged, it will directly Affects the entire turbine drive system

The invention relates to a coupler for a steam turbine, and relates to the technical field of rotating members. The coupler for the steam turbine concretely comprises a left-end half-coupling device and a right-end half-coupling device, wherein the left-end half-coupling device and the right-end half-coupling device are arranged oppositely; multiple groups of left occluding fixing blocks are equidistantly processed on the circumferential direction of the right end surface of the left-end half-coupling device; right occluding fixing blocks matched with the left occluding fixing blocks are equidistantly processed on the circumferential direction of the left end surface of the right-end half-coupling device; the left occluding fixing blocks and the right occluding fixing blocks are connectedin a crossed occluding way; a group of hydraulic unloading devices is arranged on each of the left ends and the right ends of the left occluding fixing blocks; and unloading grooves are formed in theend surfaces, corresponding to the left occluding fixing blocks, of the right occluding fixing blocks. According to the coupler for the steam turbine provided by the invention, the left-end half-coupling device and the right-end half-coupling device are arranged in a matching way, meanwhile, the left occluding fixing blocks and the right occluding fixing blocks are arranged at the butt-joint part,and the hydraulic unloading devices are arranged on the contact end surfaces of the left occluding fixing blocks, so that when the steam turbine works, a part of a large output torque of an output shaft is unloaded, and the working life of the coupler is ensured.
Description
technical field [0001] The invention relates to the technical field of shaft connectors, in particular to a shaft coupling for a steam turbine. Background technique [0002] Coupling refers to a device that connects two shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal circumstances; it is also used as a safety device to prevent the connected parts from bearing Excessive load, play the role of overload protection. [0003] The torque of the output shaft of the steam turbine is relatively large. If the general coupling only plays the role of connecting two shafts, it will generally bear too much load and cause the life of the coupling itself to be short. Once the coupling is damaged, it will directly Affects the entire steam turbine drive system. Contents of the invention [0004] The present invention overcomes the shortcomings of the above-mentioned prior art and provides a shaft coupli...
