As an important equipment in mechanical manufacturing, gear hobbing machines are widely used in the processing of various gears. However, there may be some common problems encountered during the use of gear hobbing machines. This article will explore common faults and their solutions of gear hobbing machines to ensure smooth production.

1、 Tool wear

Cutting tools are important components in gear shaping machines, and prolonged use can lead to tool wear, affecting machining accuracy and efficiency. To solve this problem, it is necessary to regularly check the wear of cutting tools and replace severely worn tools in a timely manner. At the same time, adjust the installation angle and cutting parameters of the tool to extend its service life.

2、 Loose workpiece

During the gear shaping process, loosening of the workpiece may lead to a decrease in machining accuracy or damage to the workpiece. To avoid this situation, it is necessary to ensure that the workpiece is firmly installed and fixed with suitable fixtures. Meanwhile, during the machining process, the looseness of the workpiece should be regularly checked, and the fixture should be adjusted or the workpiece should be re fixed in a timely manner.

3、 Tooth profile error

Tooth profile error is one of the common problems in gear hobbing, which may affect the meshing accuracy and transmission effect of gears. To reduce tooth profile errors, it is necessary to ensure correct tool installation and reasonable cutting parameter settings. At the same time, strengthen tool grinding and calibration work to improve machining accuracy. For gears with large errors, post-treatment processes such as heat treatment and grinding polishing can be carried out to further optimize the tooth profile.

4、 Vibration and noise

The vibration and noise generated by the gear hobbing machine during operation not only affect the physical health of operators, but may also cause damage to the equipment. To reduce vibration and noise, it is necessary to ensure stable equipment installation and reduce the impact of external vibration on the gear hobbing machine. At the same time, regularly inspect and maintain the internal components of the equipment to ensure their normal operation. For high-precision gear machining, vibration reduction devices or sound insulation devices can be used to reduce vibration and noise.

5、 Cooling system malfunction

The cooling system is an important component of the gear shaping machine, used to reduce cutting temperature and prevent tool wear. If the cooling system malfunctions, it will cause an increase in cutting temperature, exacerbate tool wear, and affect machining quality. Therefore, the working condition of the cooling system should be regularly checked, and impurities and dirt in the coolant should be cleaned in a timely manner.
