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.

What is the impact of tooth profile on the efficiency of miter gears?

The tooth profile of miter gears plays a crucial role in determining their efficiency. Miter gears are a type of bevel gears that transmit rotational motion between intersecting shafts. The tooth profile refers to the shape and design of the teeth on the gear.

The efficiency of miter gears is influenced by several factors related to the tooth profile:

  1. Tooth Shape: The shape of the teeth can significantly affect the efficiency. Ideally, the tooth profile should have a smooth and gradual transition from one tooth to the next. This ensures a uniform distribution of load and minimizes the impact of meshing forces, resulting in higher efficiency.
  2. Tooth Size: The size of the teeth, including their length and width, can impact the efficiency of miter gears. Larger teeth generally provide better load-carrying capacity and reduce the risk of tooth failure. However, excessively large teeth can increase friction and reduce efficiency.
  3. Tooth Helix Angle: The helix angle of the teeth determines the spiral orientation of the gear. Miter gears with a higher helix angle tend to have smoother meshing action and lower noise levels. This can contribute to improved efficiency by reducing friction and minimizing energy losses.
  4. Tooth Contact Pattern: The contact pattern between the teeth of miter gears should be optimized for efficient power transmission. Proper tooth contact ensures uniform load distribution and minimizes localized wear. A well-designed tooth profile creates a desirable contact pattern, resulting in higher efficiency.

Therefore, when designing or selecting miter gears, careful consideration should be given to the tooth profile. Optimal tooth shape, size, helix angle, and contact pattern can significantly enhance the efficiency of miter gears, leading to improved overall performance and reduced energy losses.

What is the role of the pitch angle in miter gear design?

In miter gear design, the pitch angle plays a significant role in determining the characteristics and performance of the gears. Here’s an explanation of its role:

1. Definition of Pitch Angle:

The pitch angle in miter gear design refers to the angle between the gear’s tooth face and a plane perpendicular to the gear’s axis. It is typically denoted by the Greek letter “β” (beta). The pitch angle determines the shape and orientation of the gear teeth.

2. Tooth Profile:

The pitch angle influences the tooth profile of miter gears. By altering the pitch angle, the shape, size, and thickness of the gear teeth can be adjusted. Different pitch angles result in variations in the tooth geometry, such as tooth thickness, tooth height, and the angle of the tooth face.

3. Contact Ratio:

The pitch angle affects the contact ratio between the gear teeth. The contact ratio refers to the number of teeth in contact at any given moment during the rotation of the gears. An appropriate pitch angle helps optimize the contact ratio, ensuring sufficient tooth engagement and load distribution across the gear surfaces. This contributes to smoother operation, reduced noise, and improved gear life.

4. Strength and Load Distribution:

The pitch angle influences the strength and load distribution capabilities of miter gears. A proper pitch angle ensures optimal load transmission across the gear teeth, preventing concentrated stresses and reducing the risk of tooth failure or breakage. By selecting the appropriate pitch angle, designers can achieve the desired strength and load-carrying capacity for the specific application.

5. Gear Efficiency:

The pitch angle also affects the efficiency of miter gears. By considering factors such as tooth contact, sliding friction, and tooth deflection, the pitch angle can be optimized to minimize energy losses during gear meshing. Efficient gear design with an appropriate pitch angle contributes to higher overall system efficiency and reduced power consumption.

6. Noise and Vibration:

The pitch angle plays a role in determining the noise and vibration characteristics of miter gears. Improper pitch angles can result in undesirable effects, such as excessive noise, vibration, and tooth impact. By carefully selecting the pitch angle, gear designers can minimize these effects, leading to quieter operation and improved gear performance.

7. Meshing Compatibility:

When using miter gears in pairs, the pitch angles of both gears should be compatible to ensure proper meshing and smooth operation. The pitch angles need to be designed and manufactured with precision to ensure accurate alignment and optimal tooth engagement.

In summary, the pitch angle in miter gear design influences the tooth profile, contact ratio, strength and load distribution, gear efficiency, noise and vibration characteristics, and meshing compatibility. By selecting an appropriate pitch angle, gear designers can achieve the desired performance, durability, and efficiency for specific applications.

Can you explain the unique design of miter gear teeth?

The design of miter gear teeth is distinct and plays a crucial role in the functionality of these gears. Here’s a detailed explanation:

1. Tooth Shape:

Miter gear teeth have a straight shape, similar to spur gears. However, unlike spur gears where the teeth are parallel to the gear axis, miter gear teeth are cut at a right angle to the gear’s face. This allows the teeth to engage correctly when two miter gears mesh together at a 90-degree angle.

2. Equal Number of Teeth:

Miter gears have an equal number of teeth on both gears in a pair. This ensures proper meshing and smooth transmission of rotational motion between the gears. The equal number of teeth is essential for maintaining a constant speed ratio and preventing any slippage or irregular motion.

3. Conical Shape:

Another unique aspect of miter gear teeth is the conical shape of the gears themselves. The teeth are cut on the conical surface, which allows for proper engagement and transmission of motion between intersecting shafts. The conical shape ensures that the teeth mesh correctly, providing efficient power transmission at the desired angle.

4. Meshing at 90-Degree Angle:

Miter gears are designed to mesh at a 90-degree angle, allowing for power transmission between intersecting shafts. The teeth are specifically cut to facilitate this arrangement, ensuring that the gears engage smoothly and transmit rotational motion without any loss or disruption.

5. Tooth Contact and Load Distribution:

When miter gears mesh, the contact between the teeth occurs along a single line, known as the line of contact. This concentrated contact area enables effective load distribution and ensures that the gear teeth bear the transmitted torque evenly. Proper tooth contact is vital for minimizing wear and maintaining the longevity of the gears.

6. Lubrication and Noise Reduction:

The unique design of miter gear teeth can influence lubrication and noise levels. Adequate lubrication is essential to reduce friction and wear between the teeth during operation. Additionally, the straight tooth profile of miter gears tends to produce more noise compared to gears with helical or curved teeth. Proper lubrication and noise reduction measures are often employed to optimize the performance of miter gears.

In summary, the unique design of miter gear teeth includes their straight shape, equal number of teeth, conical shape of the gears, meshing at a 90-degree angle, tooth contact along a line, and considerations for lubrication and noise reduction. These design features ensure efficient power transmission, proper load distribution, and reliable operation in mechanical systems that utilize miter gears.
