The ambient temperature has a certain impact on the output speed of the S47-72-0.55KW helical gear worm reducer, as follows:
Low temperature environment:
Increased viscosity of lubricating oil: Low temperature will increase the viscosity of lubricating oil and worsen the fluidity. This will increase the frictional resistance between the components inside the reducer, just like adding an additional 'burden' to transmission components such as gears, making it more difficult for the motor to drive the reducer to run. From an energy transfer perspective, the motor needs to consume more energy to overcome these resistances, which may cause a drop in the output speed. For example, when the ambient temperature drops from normal temperature to -20°C, the viscosity of the lubricant oil may increase several times, and the output speed may decrease by about 10% -20%. The specific drop depends on the specific structure of the reducer, the lubricant characteristics and the degree of low temperature.
Changes in motor performance: In low temperature environments, the magnetic flux density of the motor will decrease, and the friction of the motor will also increase, which will cause the output power of the motor to drop by 12. As the power source of the reducer, the output power of the motor will naturally affect the output speed of the reducer. In addition, low temperature may increase the starting current of the motor, making it difficult to start. Even after starting, it may not be able to achieve normal operating speed due to mechanisms such as overload protection, which will affect the output speed of the reducer.
High temperature environment:
Lubricant performance deteriorates: High temperature will reduce the viscosity of the lubricant and thin the oil film thickness, thereby reducing the lubricating effect of the lubricant. This can intensify friction between components such as gears and bearings and increase energy loss. In order to maintain the normal operation of the reducer, the motor needs to output more power to compensate for these energy losses, but the power of the motor is limited, and the output speed of the reducer may be reduced when the demand cannot be met. Moreover, high temperatures may accelerate the oxidation and deterioration of lubricating oil, further affecting its lubricating performance, resulting in a more significant decrease in output speed. For example, when the ambient temperature exceeds 40°C, as the temperature continues to rise, the output speed of the reducer may gradually decrease by about 5% - 10%.
Deformation of components such as gears and bearings: In a high temperature environment for a long time, metal components such as gears and bearings inside the reducer may undergo thermal deformation. This will lead to a decrease in the meshing accuracy of the gears and a decrease in the operation flexibility of the bearings, thereby reducing the transmission efficiency and affecting the output speed. Severe thermal deformation may even cause damage to the gears and bearings, causing the reducer to not work properly.
It is generally recommended that the operating ambient temperature of the S47 reducer be between -40℃ and 45℃ 7. If this range is exceeded, corresponding measures should be taken, such as preheating the lubricant at low temperatures, strengthening heat dissipation at high temperatures, etc., to reduce the impact of ambient temperature on the output speed and performance of the reducer.
