Customized Gear Box Gear Shaft
Products Description
The gearbox gear shaft is a component of a gearbox or transmission system that helps to transmit power from the engine to the wheels of a vehicle. It consists of a rotating shaft with gears mounted on it, which mesh with other gears in the transmission system to transfer torque and rotation between the engine and the wheels.

gear shaft hardening
Carburizing method
Carburizing method is a method of infiltrating carbon into the surface of gear shafts. It is necessary to place the gear in a carbonaceous material by heating so that the carbon element penetrates along the surface of the gear. This method is suitable for smaller gears and can improve their surface hardness
Nitriding method
The nitriding method is to heat ammonia and deposit it on the surface of the gear shaft to form a layer of nitrogen compounds, which improves the hardness and wear resistance of the gear. It can be used for large gears.
Quenching method
The quenching method is to immerse the heated gear shaft in a coolant to cool it rapidly, thereby forming a high-hardness surface layer. This method can be used for various types of gears, but attention should be paid to the temperature and cooling rate during processing.
Accuracy Grade of gear shaft
The accuracy grade of the gear shaft is an important standard for measuring the manufacturing accuracy of the gear, which directly affects the performance indicators of the gear transmission, such as stability, noise, and life. The higher the accuracy grade, the higher the manufacturing difficulty and cost. Therefore, choosing the appropriate accuracy grade requires comprehensive consideration of the performance requirements and cost budget of the transmission system.
The accuracy grade of the gear shaft is usually divided into 13 levels, from 0 to 12, of which 0 has the highest accuracy and 12 has the lowest accuracy. Specifically for the accuracy grade of the gear shaft.
Level 6 is considered a high-precision grade, which is used for high-speed and high-efficiency gears, such as important gears on aircraft, automobiles and machine tools;
Level 7 is a relatively high-precision grade, which is widely used, such as high-speed gears with small loads, machine tool feed gears, and gears in medium-speed reducers;
Level 8 is a medium-precision grade, which is used for general machinery, aircraft and automobiles. The gears in unimportant and ordinary reducers;
Level 9 is a low-precision grade, which is used for gears with low requirements at low speeds.
When selecting the accuracy grade of the gear shaft, it is necessary to consider the performance requirements, cost budget, use environment, and later maintenance and care of the transmission system. For occasions requiring high-precision transmission, such as precision machinery, instrumentation and other fields, grade 7 precision gears should be given priority; while for general industrial applications, grade 8 precision gears may be sufficient to meet the requirements.
