Novel wind power gear box

Abstract

A novel wind power gear box belongs to the technical field of mechanical gear boxes and comprises a box body for supporting, and an input end, an intermediate stage and an output end are mounted in the box body and sequentially connected. Therefore, the structure can effectively reduce the return difference problem of the planetary gear train caused by manufacturing and mounting errors, so that the processing and mounting requirements on high-speed components can be properly reduced by utilizing the structure; the reliability of a design object is improved, so that the design object can be suitable for a power generation occasion with MW-level power; by means of the structure, axial force can be counteracted, the axial force on the shaft is reduced, the joint of the shaft can be fixed through the elastic check ring and connected with the gear coupling, meanwhile, the most beneficial floating uniform load mode is achieved, and the adverse effect of unbalance loading on reliability is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical gearboxes, and in particular relates to a novel wind power gearbox. Background technique [0002] Energy and environmental issues have always been a problem for all human beings. With the continuous advancement of industrialization in the world, energy shortage and environmental pollution have become more and more public problems that all human beings need to face. For this reason, the development of new energy is particularly important. Among them, the utilization of wind energy is one of the most mature technical solutions at present. my country is rich in wind energy resources, but due to the complexity of the wind turbine itself, the core technology and manufacturing level that my country has mastered is not enough to realize the complete localization of high-power wind turbines. . Because in the wind turbine, the rotational speed of the wind rotor is very low, which is far from the rotation...

[0002] Energy and environmental issues have always been a problem for all human beings. With the continuous advancement of the industrialization process in the world, energy shortage and environmental pollution have become more and more public problems that all human beings need to face. Therefore, the development of new energy is particularly important. Among them, the use of wind energy is one of the most mature technical solutions at present. my country is rich in wind energy resources, but due to the complexity of wind turbines, the core technology and manufacturing level that my country has mastered are not enough to realize the complete localization of high-power wind turbines.

However, the bevel gear used in this device has high precision requirements when used, and at the same time, it is not conducive to the realization of floating load sharing, and it is easy to generate noise during operation when the lubrication is not good

[0014] However, due to the complex working conditions and environment of the entire wind power gearbox system, it often works under harsh conditions, and it is easy to generate impact loads on the input end to cause damage to the internal structure. Therefore, if the internal load distribution cannot be properly handled, that is, load equalization, it will cause excessive friction and heat generation, which will make the lubrication failure more serious, cause the parts to wear and fail, cause noise or even the overall failure
