Transmission characteristics of three horse copper worm gear
The transmission of copper worm gear is the most important way of transmission in machinery. Its transmission power range is large, transmission efficiency is high, and it can drive the movement and power between any two axes.
The movement and power transmission of copper worm gear are accomplished in the interaction and relative motion of each pair of meshing tooth surfaces in the gear mechanism, and friction will inevitably occur between them. In order to maintain the working efficiency and prolong the service life of gear mechanism, it is necessary to form adsorption film and reaction film on the tooth surface of lubricant - gear oil, so as to reduce friction coefficient, friction and wear. Gear oil is an important lubricating material for ensuring the efficiency of gear transmission and prolonging the service life of gears. According to statistics in 2000, China's annual output of vehicle gear oil 36,000 tons, working gear oil 15,000 tons, complete varieties, quality reached or approached the international advanced level, fully meet the needs of the domestic lubricating oil market. But the proportion of gear oil in lubricating oil product structure is 2.3% in China, which is lower than 5% in developed countries. The reason is that a considerable number of gear equipments in China use full-loss system oil to cause poor lubrication and loss of equipment.
Worm gear and worm oil, mainly used for copper-steel pairs of cylindrical and double-head type of worm gear and worm pairs to withstand light loads, transmission in a smooth and non-impact; L-CKE/P heavy-duty worm gear and worm oil, mainly used for copper-steel pairs of cylindrical bearing heavy loads, transmission in vibration and impact of worm gear and worm pairs, including double-head and multi-head Head worm gear pair. Worm gear and worm device can achieve a large transmission ratio in a small space at one time, the tooth surface is linear contact, coupled with several teeth at the same time meshing with each other, in order to transmit high load and noise-free operation. Worm gear drive has different characteristics from gear transmission, and also has special requirements for lubricating oil. Worm and worm gear transmission speed is high and calorific value is high. Worm wheels are often made of bronze, sometimes brass or cast iron. Worms are usually made of alloy or carbon steel. Matching the material can reduce wear and prevent cementing. In order to prevent the chemical corrosion of oil to copper worm gear, the sulfur content, chlorine content and neutralization value in oil are strictly required. In order to investigate the transmission efficiency of worm gear and worm oil, the temperature rise of oil, the wear and tear of worm gear pair and the bearing capacity of worm gear, besides the routine analysis and evaluation, it is necessary to make the evaluation of worm gear and worm oil bonding bench and efficiency bench.
