The transmission function of gearbox components has multiple characteristics, as follows:
1. Stable and correct transmission ratio
       Correct transmission: The gearbox achieves power transmission through interlocking gears, and its transmission ratio is determined by the number of teeth on the gears. As long as the machining and assembly accuracy of the gears are guaranteed, a stable and correct transmission ratio can be provided, ensuring a fixed speed relationship between power output and input. It is widely used in equipment that requires correct transmission, such as machine tools and clocks.
       Constant speed ratio: During the operation of the gearbox, regardless of changes in load size and speed, as long as the modulus, number of teeth, and other parameters of the gears are determined, the transmission ratio remains unchanged, providing reliable transmission guarantee for the stable operation of the equipment, making the operating speed and action of the equipment predictable and controllable.
2. High transmission efficiency
       Low energy loss: Gear transmission is a type of meshing transmission, where the contact area between gears is small, the relative sliding speed is low, and the friction loss is small. Under good lubrication conditions, the transmission efficiency of a gearbox can usually reach over 95%, effectively transmitting power from the input shaft to the output shaft, reducing energy loss during transmission, and improving the energy utilization efficiency of the equipment.
       Efficient transmission of power: Due to the efficient transmission characteristics of the gearbox, it can transmit large power in a small space, suitable for various occasions that require high-power transmission, such as automobiles, ships, industrial machinery, etc. It can meet the high requirements of equipment for power transmission while reducing energy consumption and operating costs.
3. High transmission torque
       Strong load-bearing capacity: The gears of the gearbox are usually made of high-strength alloy steel materials and processed through quenching, grinding and other processes, with high hardness and strength, capable of withstanding large torque and impact forces. By reasonably designing parameters such as modulus, number of teeth, and tooth width of gears, gearboxes can meet the torque transmission requirements of different equipment. From small electric tools to large mining machinery, wind turbines, etc., gearboxes can be used to transmit power.
       Multi gear collaborative work: In some large gearboxes, multiple gears are usually used to mesh with each other to transmit power. By increasing the number of gears and arranging their positions reasonably, torque can be distributed to multiple gears, further improving the load-bearing capacity and torque transmission ability of the gearbox, ensuring stable operation of the equipment under high load conditions.
4. Multiple transmission forms can be realized
       Changing the transmission direction: By setting different types of gears in the gearbox, such as cylindrical gears, bevel gears, worm gears, etc., different directions of power transmission can be achieved, such as converting horizontal power transmission into vertical power transmission, or converting rotational motion into linear motion, etc., to meet the transmission needs of the equipment in different working scenarios.
       Multi speed transmission: The gearbox can achieve multi speed transmission by setting gear sets with different gear ratios, allowing the equipment to obtain different speeds and torques under different working conditions. For example, the gearbox of a car is a typical multi speed transmission gearbox, which can switch different gear combinations according to the vehicle's driving speed and road conditions to achieve different gear shifts and improve the vehicle's power performance and fuel economy.
5. Reliable work and long lifespan
       Durable and sturdy structure: The structure of a gearbox is usually compact, with strong connections between components such as gears, shafts, and bearings, which can maintain a stable working state during long-term operation. Under normal operating conditions, gearboxes that have been properly designed and manufactured can run for a long time without frequent maintenance and component replacement, and have high reliability and service life.
       Low maintenance cost: Due to the high reliability of the gearbox, its maintenance cost is relatively low. Only regular inspections of the gear wear, replenishment or replacement of lubricating oil, cleaning of impurities inside the box, etc. are needed to ensure the normal operation of the gearbox, reduce downtime and maintenance costs caused by transmission system failures, and improve the overall operating efficiency and economic benefits of the equipment.
