Gear accuracy and processing instructions

The gear precision and processing instructions are as follows, for reference and understanding. If you are unclear or related requirements, you can consult EP free of charge.

XNUMX. Gear accuracy:

The gear accuracy grade depends on the gear application range and is usually determined by the part requirements.

Gears are usually classified according to the required tolerances of the gears after machining.

most commonCylindrical gearThe accuracy classification standard is DIN 3962, which is for differentGear parametersTake measurements and classify them on a scale of 1-12.

Other user-specific standards are also common, but their evaluation parameters are roughly the same as the DIN 3962 standard.

XNUMX. Gear processing:

It is very important to choose the most efficient and accurate machining method and gear machining tool.Gear processingfield.

The choice of tool and gear processing method depends on the part, production process and batch size.

Obtaining tight dimensional tolerances is an important problem in the soft processing stage of gears.

In order to make the turning process of hard parts relatively straightforward, careful preparations are made in the quenching stage, and then the gears will be hard processed.

Predictable machining and good surface quality are essential in hard part turning.

Due to electric transportation, a new gearbox design, and ensuring flexibility and high productivity at the same time, the gear machining process will undergo great changes.

Compound machining of gear/spline parts will become the norm, and the focus will no longer be on the common traditional gear processing machine tools.

Strong tooth scraping will replace gear shaping, tooth pulling and spline rolling, and to some extent replace gear hobbing. Strong tooth scraping will become the focus.

The above is the gear processing and precision related instructions shared today, including but not limited to.
