To improveGear processingThe industry's manufacturing precision, production efficiency, clean production and quality, gear manufacturing machine tools and gear manufacturing technology have shown a "full numerical control" development trend.The machine tool has the following advantages after the numerical control of each motion axis and the linkage between some of the axes:

Gear processing technology

1. Improve the functions of CNC lathes, such as hobbing small tapers and drum transmission gears.

2. After shortening the transmission chain and adopting semi-closed loop or full closed loop control, the positioning accuracy and repeat positioning accuracy of each axis can be improved through numerical control compensation, thereby improving the machining accuracy and Cp value of the machine tool, and improving the reliability of the machine tool.

3. When replacing products, the gear shaper also saves the time to replace the inclined guide, which greatly reduces the auxiliary processing time, increases the flexibility of the machine tool, and saves calculation and replacement of variable gears, differential gears, feed gears and The time of the main shaft gear.

4. As the mechanical structure becomes simple, it can be designed to increase the rigidity of the machine tool and reduce thermal deformation.

5. There is no mechanical connection between the shafts, so the structural design becomes typical, which is conducive to the main implementation of modular design and manufacturing.The gears have 13 accuracy levels, arranged with numbers 0-12 from low to high.From the higher level 0, you can know the lower level 12.Gear accuracy refers to a grade divided by the comprehensive error of the gear shape, including some important parameters such as tooth profile, tooth direction, and radial runout.Gear accuracy mainly controls the transmission accuracy between gears during operation and whether the backlash can be small.If there is an impact load, the accuracy should be slightly improved to reduce the damage to the gear caused by the impact load.The choice of gear accuracy grade should be determined according to the purpose of the transmission, use conditions, transmission power, peripheral speed, performance indicators or other technical requirements.
