Planetary reducer is one of the commonly used types of reducers in mechanical transmission. Its main function is to convert the high-speed rotation of the motor into low-speed and high torque output. With its advantages of high precision, high transmission efficiency, and small size, it is widely used in servo, stepper, and DC motor transmission systems, while ensuring precision transmission.
Low energy planetary reducers are widely used in industries such as automation equipment, mechanical manufacturing, and robot manufacturing to increase torque, reduce load, and reduce the inertia ratio of the motor in the transmission system. They have advantages such as high stability, high precision, and long service life. One of the most important parameters is transmission efficiency, which has a significant impact on the performance and service life of machine equipment in practical applications.
Therefore, when using precision planetary reducers, attention should be paid to the issue of transmission efficiency. What will affect the transmission efficiency of high transmission efficiency planetary reducers.
In a planetary gear reducer, gear matching is an important part of generating friction and transmitting power. However, due to the certain elasticity of the gear during rotation, there is a meshing gap, which leads to insufficient gear matching. When the gear rotates, the friction between the meshing surfaces generates heat, causing the gear to lose a certain amount of energy.
However, the precision of gear meshing determines the quality of torque transmission between gears. If the design of parameters such as gear modulus, gear, and tooth thickness is unreasonable or the manufacturing process is poor, it will lead to slight relative sliding between gears, reducing mechanical efficiency; Secondly, the important component of the reducer is the bearing. Inside the reducer, the bearing plays an important supporting role. However, friction between the bearings during high-speed operation can also generate heat, causing the reducer to lose some energy. However, the bearings in the reducer also have certain losses when transmitting torque. High quality bearings can reduce rolling resistance and friction, and improve mechanical efficiency.
The lubrication method and lubricating oil of the planetary reducer can also affect mechanical efficiency. The lubrication methods include oil immersion and oil mist. The oil immersion lubrication method requires lubricating oil to be filled in the planetary reducer, while the oil mist lubrication method requires lubricating oil to be filled in the planetary reducer. The oil mist lubrication method is to spray lubricating oil into the planetary reducer through atomization for lubrication, and the selection of lubricating oil is also very important.
If the viscosity of the lubricating oil is not good enough, it will lead to increased friction, thereby reducing mechanical efficiency. Another point is that it is very important to prevent leakage and pollution of the textile planetary reducer oil. Suitable lubricating oil and lubrication methods need to be added to the interior of the reducer to reduce friction between parts. At the same time, it can also reduce the high-temperature energy of the planetary reducer, avoid overheating and combustion of parts, and effectively improve mechanical transmission efficiency.
