Abstract

The invention relates to an anti-interference precision transmission device of an aero-engine blade grinding and finishing shaft, and belongs to the technical field of machining, the anti-interference precision transmission device comprises a machine shell and a main shaft, one end of the main shaft extends out of the machine shell, a first belt pulley is arranged at the end, extending out of the machine shell, of the main shaft, and a damping assembly is arranged between the first belt pulley and the main shaft; the damping assembly comprises a shaft sleeve and a first bearing, the shaft sleeve is sleeved with the main shaft and fixed to the machine shell, the first bearing is sleeved with the shaft sleeve, a first limiting ring is fixed to the inner wall of the first belt wheel, and the bearing outer ring, close to the machine shell, of the first bearing abuts against the first limiting ring; an end cover is arranged on the side, away from the machine shell, of the shaft sleeve and comprises a first end cover and a second end cover fixed to the first end cover, the second end cover and one end of the main shaft are fixed to the main shaft, the first end cover is fixed to the first belt pulley, and a limiting assembly for limiting the side, away from the machine shell, of the first bearing is connected to the first end cover. The device has the effect of reducing the vibration condition of the main shaft in the rotating process.

Description

technical field [0001] The present application relates to the technical field of mechanical processing, in particular to an anti-interference precision transmission device for the grinding and trimming shaft of an aeroengine blade. Background technique [0002] In the field of aerospace technology, aeroengine blades play an important role. There are many types of aviation blades, different sizes, and complex curved surfaces. The machining accuracy of aviation blades plays a vital role in the performance and operation safety of aero-engines. [0003] The main shaft of the grinding machine for aero-engine blades generally adopts the transmission mode of belt and pulley, and the main shaft is driven by the pulley. When the belt drives the pulley to rotate, the belt is prone to vibration, and the vibration of the belt will be transmitted to the main shaft, causing the main shaft to vibrate during the rotation process, reducing the accuracy of the workpiece.
