Gear processing process
1. Forging
Hot die forging is still a widely used blank forging process for automotive gear parts. In recent years, cross wedge rolling technology has been widely used in shaft machining. This technology is especially suitable for making blanks for complicated stepped shafts. It has high precision, small machining allowance and high production efficiency.
2. Normalizing
The purpose of this process is to obtain the hardness suitable for subsequent gear cutting and prepare for the final heat treatment, so as to effectively reduce the heat treatment deformation. The gear steel used is usually made of 20CrMnTi. Due to the great influence of personnel, equipment and environment, the general normalizing makes it difficult to control the cooling speed and uniformity of the workpiece, resulting in large hardness dispersion and uneven metallographic structure, which directly affects metal cutting and final heat treatment, making the thermal deformation large and irregular, and the quality of parts uncontrollable. Therefore, isothermal normalizing process is adopted. Practice has proved that the adoption of isothermal normalizing effectively changes the disadvantages of general normalizing, and the product quality is stable and reliable.
3. Turning
In order to meet the positioning requirements for high-precision gear processing, CNC lathes are used to process gear blanks, and mechanical clamping is used without regrinding the turning tool. The simultaneous processing of the hole diameter, end face and outer diameter is realized under 1 clamping, which not only ensures the perpendicularity requirements of the inner hole and end face, but also ensures the small size dispersion of large batch of gear blanks. Thus, the accuracy of gear blank is improved and the machining quality of subsequent gears is ensured. In addition, the high efficiency of CNC lathe processing also greatly reduces the number of equipment, which is economical.
4. Hobbing and gear shaping
The equipment used to process the gear is still a large number of ordinary hobbing machines and gear shapers. Although it is convenient to adjust and maintain, the production efficiency is low. If large capacity is achieved, multiple machines need to be produced at the same time. With the development of coating technology, the re coating of hobs and slotting tools after grinding is very convenient. The coated tools can significantly improve their service life, generally by more than 90%, effectively reducing the number of tool changes and grinding time, with significant benefits.
5. Shaving
radial shaving technology is widely used in the production of large quantities of automobile gears because of its high efficiency and the easy realization of the requirements for the modification of the designed tooth profile and tooth direction. Since the company purchased the special radial shaving machine of Italian company through technical transformation in 1995, the technology has been applied maturely and the processing quality is stable and reliable.
6. Heat treatment
Automobile gears require carburizing and quenching to ensure their good mechanical properties. Stable and reliable heat treatment equipment is essential for products that are no longer subject to gear grinding after heat treatment. The company has introduced the continuous carburizing and quenching production line of German Louyi Company, and has obtained satisfactory heat treatment effect.
7. Grinding
It is mainly used to finish the inner hole, end face, shaft outer diameter and other parts of the gear after heat treatment to improve the dimensional accuracy and reduce the form and location tolerance.

How do you prevent backlash and gear play in a worm gear mechanism?

Preventing backlash and gear play is essential for maintaining the accuracy and performance of a worm gear mechanism. Here’s a detailed explanation of how to prevent backlash and gear play in a worm gear mechanism:

Backlash refers to the play or clearance between the teeth of the worm and the worm wheel in a worm gear mechanism. It can result in inaccuracies, positioning errors, and reduced efficiency. Here are some measures to prevent or minimize backlash and gear play:

  • Precision manufacturing: Accurate and precise manufacturing of the worm and worm wheel is crucial to minimize backlash. High-quality machining techniques, such as grinding, can be employed to achieve precise tooth profiles and minimize any gaps between the teeth. Careful attention to the design and manufacturing tolerances can help reduce backlash.
  • Tight meshing clearance: Proper adjustment of the meshing clearance between the worm and the worm wheel can help minimize backlash. The meshing clearance should be set as small as possible without causing interference or excessive friction. Close clearance ensures a tighter fit between the teeth, reducing the amount of play or backlash.
  • Anti-backlash mechanisms: Anti-backlash mechanisms can be incorporated into the worm gear system to reduce or eliminate backlash. These mechanisms typically consist of spring-loaded components or adjustable devices that help compensate for any clearance between the teeth. They apply a constant pressure to keep the teeth engaged tightly, reducing the effects of backlash.
  • Preload: Applying a preload to the worm gear system can help minimize backlash. Preload involves applying a slight compressive force or tension to the components, ensuring they remain engaged and eliminating any clearance. However, it is important to apply the appropriate preload to avoid excessive friction and wear.
  • Lubrication: Proper lubrication is crucial for minimizing backlash and reducing gear play. Lubricants with suitable viscosity and properties should be used to ensure smooth and consistent operation of the worm gear mechanism. Good lubrication helps reduce friction, wear, and any potential clearance that can contribute to backlash.
  • Regular maintenance: Regular inspection and maintenance of the worm gear mechanism can help detect and address any developing backlash or gear play. Routine checks can identify signs of wear, misalignment, or improper lubrication, allowing for timely adjustments or replacements to minimize backlash and maintain optimal performance.

It’s important to note that completely eliminating backlash in a worm gear mechanism may not always be possible or desirable. Some applications require a certain level of backlash to accommodate thermal expansion, compensate for positional errors, or allow for smooth operation. The acceptable level of backlash depends on the specific requirements of the application.

When implementing measures to prevent backlash and gear play, it is crucial to strike a balance between minimizing backlash and ensuring smooth, reliable operation. The specific techniques and approaches used to minimize backlash may vary depending on the design, manufacturing, and application requirements of the worm gear mechanism.

What are the environmental considerations when using worm gears?

When using worm gears, there are several environmental considerations to keep in mind. Here’s a detailed explanation of these considerations:

  1. Lubrication: Proper lubrication is essential for the efficient and reliable operation of worm gears. Lubricants help reduce friction and wear between the gear teeth, resulting in improved efficiency and extended gear life. When selecting lubricants, it is important to consider their environmental impact. Environmentally friendly lubricants, such as biodegradable or synthetic lubricants with low toxicity, can be used to minimize the potential harm to the environment in case of leakage or accidental spills.
  2. Leakage and contamination: Worm gear systems are susceptible to lubricant leakage, which can cause environmental pollution. It is important to ensure that the gear housing is properly sealed to prevent lubricant leakage into the environment. Regular inspections and maintenance should be carried out to detect and repair any leaks promptly. Additionally, measures should be taken to prevent contaminants such as dust, dirt, and water from entering the gear system, as they can degrade the lubricant and affect the gear performance.
  3. Energy efficiency: Worm gears, like any mechanical power transmission system, consume energy during operation. It is important to consider energy efficiency when selecting and designing worm gear systems. Optimal gear design, proper gear selection, and efficient lubrication practices can contribute to reducing energy consumption and minimizing the environmental impact associated with energy use.
  4. Noise and vibration: Worm gears can generate noise and vibration during operation. Excessive noise can contribute to noise pollution, while high vibration levels can impact the surrounding equipment and structures. To mitigate these effects, it is important to design and manufacture worm gears with low noise and vibration characteristics. This can involve careful gear design, proper lubrication, and the use of vibration-damping materials or mechanisms.
  5. End-of-life considerations: At the end of their service life, worm gear components may need to be replaced or recycled. Disposal of worn-out gears should be done in accordance with applicable environmental regulations. Whenever possible, recycling or reusing gear components can help reduce waste and minimize the environmental impact associated with the disposal of gear materials.
  6. Environmental regulations: Compliance with environmental regulations and standards is crucial when using worm gears. Different regions may have specific regulations governing the use and disposal of lubricants, materials, and manufacturing processes associated with gear systems. It is important to stay informed about these regulations and ensure compliance to avoid any adverse environmental impact and legal consequences.

By considering these environmental factors, it is possible to minimize the ecological footprint of worm gear systems and promote sustainable practices in their use and maintenance. This includes selecting environmentally friendly lubricants, implementing proper sealing and maintenance procedures, optimizing energy efficiency, and adhering to relevant environmental regulations.
