China's industry is remembered by the world, and China's gear industry is the leader of the world's gear industry. The progress goal of China's gear industry is determined as "promoting China's gear manufacturing power and export power".
In the process of progress, China's gear industry will reveal four major situations: the market will reveal a large number of new gear products with international standards and independent intellectual property rights. It can be widely used in metallurgy, mining, chemical industry, building materials, hoisting, transportation, textile, papermaking, instruments, plastics, rubber, construction machinery, energy and other industrial departments.
The high-speed shaft rotation of hardened cylindrical gear reducer shall not be greater than 1500 rpm. The circumferential speed of gear transmission shall not be greater than 20m / s. The operating ambient temperature is - 40-45 ℃. If it is lower than 0 ℃, the lubricating oil shall be preheated to above 0 ℃ before startup. The reducer can be used for operation in both positive and negative directions.
The lubricating oil shall be replaced after the first use or new replacement of the worm pair and 150-400 hours of operation, and the subsequent oil change cycle shall be less than or equal to 4000 hours. Regularly check the quantity and quality of oil, keep enough lubricating oil, and replace the oil mixed with impurities or deterioration in time. The oil filling quantity shall be in accordance with the requirements of the table. It is forbidden to mix oils of different brands. Oils of the same brand but different viscosity are allowed to be mixed. See attached table 1 for oil injection volume. The operating ambient temperature of the reducer is - 40 ~ + 40 ℃ according to attached table 2. When the ambient temperature is lower than 0 ℃, the lubricating oil must be heated above 0 ℃ or the lubricating oil with low freezing point must be used before startup.
