Method for checking intensity of wind power locking disk

Abstract

The invention discloses a method for checking the intensity of a wind power locking disk, belonging to the field of design of wind power generating equipment. The method comprises the following checking steps of: (1) computing the positive pressure of each conical contact surface between an outer sleeve and an inner ring; (2) computing the pressure intensity and interference magnitude of each conical contact surface between the outer sleeve and the inner ring after a bolt is screwed and ensuring the maximum pressure intensity and interference magnitude on the premise of ensuring that each component is not deformed plastically; (3) computing the pressure intensity and interference magnitude of a contact surface between the inner ring and a shaft sleeve after a bolt is screwed and ensuring the maximum pressure intensity and interference magnitude on the premise of ensuring that each component is not deformed plastically; (4) computing the pressure intensity and interference magnitude ofa contact surface between a shaft sleeve and a main shaft after a bolt is screwed and ensuring the maximum pressure intensity and interference magnitude on the premise of ensuring that each componentis not deformed plastically; and (5) computing the maximum torque which can be transferred by the contact surface between the main shaft and the shaft sleeve. According to the method, plastic deformation of each component material and the capabilities of the shaft sleeve and the main shaft for transferring a rated torque after the wind power locking disk is locked can be verified, the rationalityof the design size of the locking disk can be verified effectively, the manufacturing risk is lowered, and the product yield is increased.

Description

technical field [0001] The invention belongs to the technical field of wind power generation equipment design, and in particular relates to a method for checking the strength of a wind power locking disk. Background technique [0002] As a renewable resource, wind energy has the advantages of not requiring fuel, occupying no cultivated land, and having no pollution. It has become the energy industry with the most development potential in the 21st century. my country's wind energy resources are very rich, and the development prospect of wind power industry is very broad. Moreover, its technology is mature, and the construction period is short. It is a safe and reliable energy source. According to the requirements of the national new energy industry planning, my country should vigorously develop the domestic independent development of clean energy power generation equipment. In the long run, with the continuous deepening of technological progress in wind power generation, bot...

Problems solved by technology

[0004] When calculating the interference of the contact surface and the yield limit of the containment part and the containment part, the traditional checking method is to regard the two parts in contact with each other as the containment part and the containment part respectively, while the actual situation is that the jacket, inner ring, The contact surfaces of the shaft sleeve and the main shaft are all interference fits, and the objects on both sides of any contact surface can be regarded as a whole, which leads to the result obtained by the traditional calculation method inconsistent with the actual situation, resulting in excessive errors.
