Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of running-in device, especially, relate to a large -scale machinery main shaft running-in device. BACKGROUND

[0002] The existing running-in device is mainly used for small machinery main shaft running-in. The driving motor is fixed, the position of the dovetail groove sliding seat of the machinery main shaft is adjusted by using the function of dovetail groove sliding, so that the tightness of the belt meets the transmission requirements. The premise of this adjustment mode is that the mass and diameter of the machinery main shaft are relatively small, and the dovetail groove sliding seat can be pushed on the plane. If the mass or diameter of the machinery main shaft is too large, it is easy to cause derailment danger, and it is difficult to adjust the tightness of the belt. The large-scale machinery main shaft generally adopts the clamping seat to fix the machinery main shaft on the dovetail groove sliding seat, and the installation steps are cumbersome when the mass and diameter are too large, and the appearance of the main shaft is often scratched.
