Abstract

The invention discloses a wind power locking disc test stand, which comprises a support frame, a shaft sleeve, a main shaft, an arm of force, a base, a key and a bolt and is characterized by also comprises a convex spherical base plate, a concave spherical top cover and a jack, wherein the main shaft is arranged in the support frame; the shaft sleeve is arranged at one end of the main shaft and is connected with the support frame through the key; the arm of force is arranged at the other end of the main shaft; the convex spherical base plate is arranged at the stress position of the arm of force; the concave spherical top cover is arranged on the jack; and the support frame and the jack are arranged on the base. The test stand enhances safety and reliability, lowers equipment cost and hasthe advantages of simple structure, short testing time, small testing site and the like.

Description

technical field [0001] The invention relates to a torque test device, in particular to a wind power locking disk torque test bench. Background technique [0002] The locking disc plays a role in transmitting torque in the wind power generating set. It connects the main drive shaft and the gearbox shaft in the wind generating set into one, and works continuously and permanently. The main structure of the existing locking disc torque test bench is as follows: a plate is set up on the base frame, the shaft sleeve is installed on the center hole of the vertical plate, one end of the main shaft is put into the shaft sleeve to form a clearance fit, and the other end of the main shaft is matched with the symmetrical force The arms are fastened together with bolts, and the two ends of the force arm are respectively equipped with hydraulic cylinders and pressure sensors with opposite forces. The force arm is loaded by hydraulic pressure, and the torque is transmitted to the locking d...
