Abstract

The invention relates to the field of gear production and processing, in particular to a spiral cylinder inner gear groove grinding device. The spiral cylinder inner gear groove grinding device comprises a cylindrical grinding bracket, a lathe bed, a gear fixture and a driving system, wherein grinding heads are arranged on the bracket, the grinding heads are spirally wound on the cylindrical surface of the bracket, and the winding distance of the grinding heads is consistent with that of to-be-processed gears; 3 to 6 grinding heads which are close to each other and are used for grinding adjacent gear grooves of the to-be-processed gears form a grinding group, and a plurality of grinding groups are rotatably and symmetrically arranged relative to the central axis of the grinding bracket; the gear fixture is arranged on the driving system, and a gear workpiece can be clamped and driven to rotate by the gear fixture; and the fixture can be driven to move to the grinding bracket by the driving system. The device has the advantages of uniform stress in a grinding process and high grinding precision.

Description

technical field [0001] The invention relates to the field of gear production and processing, in particular to a tooth groove grinding device for spiral cylindrical internal 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 that it will cause bur...
