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.
