In order to improve efficiency, vertical reducers usually use non-ferrous metals as gears, and worms use harder steel.Given its sliding friction speed transmission, it will generate higher heat during operation, resulting in differential thermal expansion between the control and seal of the reducer.Therefore, there is a gap between the matching surfaces, and due to the increase in temperature, the oil becomes thinner, which is easy to cause leakage.The main reasons are as follows: 1. Whether the material matching is suitable.Every reducer has its vital components: gears, bearings and oil seals.When these accessories are not made of superior materials and advanced technology for production.The quality of your device cannot be guaranteed. 2. By imitating the Soviet technology from the 1940s to the 1950s, most of the reducers from the 1960s were built.Although they were promoted later, they were limited to the design, craft level and equipment conditions at that time, and their overall level was far from the foreign level.Since the reform and opening up, many advanced processing equipment have been introduced.Through the introduction, digestion and absorption of overseas advanced technology and scientific research, we have gradually mastered the design and establishment technology of various high-speed and low-speed heavy-duty gear components.Greatly enhanced materials, heat treatment textures and gear machining accuracy. 3. Stable operation and low noise. 4. Small size, light weight, long service life and high bearing capacity. 5. The reducer is composed of gear pairs of various levels.For example, the necessary purpose of deceleration can be achieved by driving a large gear with a small gear.If a multi-stage structure is used, the speed can be greatly reduced. 6. SelectionMaintenance grease When selecting grease according to the bearing load of the travel reducer, choose the grease with small penetration for heavy load.When working under high pressure, it has high oil film strength and extreme pressure function in addition to small penetration.Choose lubricating grease according to environmental conditions. Calcium lubricating grease is not easy to dissolve in water and is suitable for dry and less water environment.When selecting a grease based on operating temperature, the main policies should be dropping point, oxidation stability and low temperature performance.The dropping point can often be used to guess the high temperature function.The actual working temperature of the bearing should be 10-20°C lower than the dropping point.The service temperature of synthetic grease should be 20-30°C below the drop point.
