Description

Single leg support grinding head device

technical field

The utility model relates to a single-leg supporting grinding head device, which belongs to the technical field of gear grinding.

Background technique

Gear transmission is the most widely used form of mechanical transmission, which has the characteristics of high transmission efficiency and compact structure. However, due to the inevitable manufacturing and installation errors, the vibration and noise of gear transmissions are often relatively large, especially in some high-power transmissions (such as megawatt-level wind power speed increasers, marine gear reducers, etc.) Vibration and noise problems are particularly prominent in transmissions with high comfort requirements (such as automobile gearboxes, etc.). Grinding is a mature and effective technology to reduce the vibration and noise of gear transmission.

Generally, the grinding wheel frame of the grinding tool part of the gear grinding machine is supported by double legs, which is very troublesome for the replacement of the belt and pulley parts, increases the auxiliary time of mechanical processing, reduces the processing efficiency, and affects the processing progress.
