Involute spiral cylindrical outer gear grinding equipment

Abstract

The invention relates to the field of spiral gear machining and manufacturing equipment, in particular to involute spiral cylindrical outer gear grinding equipment. The involute spiral cylindrical outer gear grinding equipment comprises a cylindrical grinding support, a lathe bed, a supporting column and a driving system, wherein grinding heads are arranged on the inner wall of the grinding support, the grinding heads spirally surround the inner wall of the grinding support, and the winding distance of the grinding heads is consistent with that of a machined gear; the plurality of grinding heads which are close to one another and are used for grinding the adjacent tooth grooves of the to-be-machined gear form one grinding set, and the plurality of grinding sets are rotationally and symmetrically arranged relative to the central axis of the grinding support; and one end of the supporting column is installed on the driving system, the other end of the supporting column can be inserted into a machined gear shaft hole and drive the gear to rotate, the central axis of the supporting column coincides with the central axis of the grinding support, and the driving system can drive the supporting column to move along the central axis direction of the supporting column. The equipment has the advantages of being uniform in stress in the grinding process and high in grinding precision.

Description

technical field [0001] The invention relates to the field of helical gear processing and manufacturing equipment, in particular to grinding equipment for involute helical cylindrical external gears. Background technique [0002] The helical cylindrical gear has become a high-precision gear commonly used in precision instruments, meters and automobiles because of its stable transmission and small vibration. [0003] During the grinding process of gears, a rough structure parallel to the tooth root will be produced. These defects appear to be amplified during the meshing process, resulting in enlarged meshing frequencies and higher-order meshing characteristics. This phenomenon is thought to be caused by the gear grinding process, and also occurs in the gear honing process where cylindrical gears are used for precision operations. Combining grinding after grinding is not a good option for several reasons. The additional process is not only costly, but the main reason is tha...
