Temperature changes have many effects on the performance of JZQ500-23.34-1 soft tooth surface reducer, as follows:
Effect on lubrication effect : Temperature changes will change the viscosity of the lubricating oil. At low temperatures, the lubricating oil will become too viscous and deteriorate in fluidity, making it difficult to form a good lubricating film on the surfaces of components such as gears and bearings, resulting in a decrease in lubricating effect and increasing friction and wear between components. At high temperatures, the viscosity of the lubricant oil will decrease, which will become too thin, and will also not be effectively lubricated, which will also aggravate wear.
Influence on component size and gap : Metal components have the characteristics of thermal expansion and contraction. When the temperature rises, metal parts such as gears, shafts, and other metal parts inside the reducer will expand, which may cause the fitting gap between the components to become smaller, affecting the transmission accuracy, and in severe cases, it may even cause the components to be stuck. When the temperature drops, the components shrink and the gap may increase, which will cause impact and vibration to the gears during operation, reduce the stability of the transmission, accelerate the wear of the gears, and also affect the positioning accuracy of the reducer.
Influence on material performance : Low temperature will reduce the toughness of the gear material of the soft tooth surface reducer, increase the brittleness, significantly reduce the impact toughness, and increase the hardness value, thereby reducing the load-bearing capacity of the gear and increasing the risk of brittle fracture of the gear. High temperature will weaken the strength of the metal material, affecting its load-bearing capacity, and being in a high-temperature environment for a long time will also accelerate the aging of parts.
Influence on sealing performance : Temperature changes will affect the sealing performance of the reducer. At high temperatures, the seal may expand, age, harden or deform, resulting in a lax seal and lubricant leakage. At low temperatures, the seal may shrink, which will also degrade the sealing performance. External impurities such as water vapor, dust, etc. can easily enter the reducer, contaminating lubricating oil and damaging parts.
Effect on transmission efficiency : Increased temperature may cause the friction coefficient of the transmission system to change. In some cases, the friction coefficient decreases with the increase of temperature, which can reduce friction loss and improve transmission efficiency. But at the same time, high temperatures will reduce the viscosity of the lubricant, deteriorate the lubricating effect, increase friction, and lead to a decrease in transmission efficiency. In addition, changes in component size and gap changes caused by temperature changes will also affect the transmission efficiency.
Impact on motor performance : Reducers are usually used in conjunction with motors. High temperatures will make the motor heat dissipation performance worse, causing the motor temperature to rise. In order to maintain normal operation, the motor may consume more energy to overcome the additional thermal load, thereby reducing efficiency. At the same time, it will accelerate the aging of motor insulation materials, affecting the service life and safety of the motor.
