In modern industry, open gear transmissions and closed gear transmissions have coexisted as two forms of gear transmission. In the cement, metallurgy, mining and other industries, open gear transmission applications are extremely common, especially in some very large rotating equipment, such as grinders, dryers, mining shovel and so on.
Compared with foreign lubricant products, the performance of domestic open gear lubricant products is quite different. In actual use, various accidents have also occurred. In foreign countries, asphalt lubricant products have long been eliminated, solvent dilution type. Lubricating oil products generally contain chlorine in the solvent, and the international requirements for lubricants are becoming more and more strict. This kind of lubricating oil products are also being eliminated.
At present, the latest type of lubricating oil products are synthetic products, which have excellent extreme pressure and anti-wear properties, excellent thermal oxidation stability and anti-pollution, and are called environmentally friendly products.
The high viscosity of open gear lubricants is an important aspect of ensuring its adhesion properties. Solid lubricants play an important role in open gear oils. The lubrication method of the open gear cannot be lube oil-type circulating lubrication. Therefore, the lubrication method has a certain influence on the lubrication. In the past, some enterprises often used the small oil groove in the small gear, relying on the rotation of the pinion. Lubricating oil is lubricated on the large gear; even in the form of hand-applied lubricant.
As a modern large open gear, it is mostly lubricated with a modern spray device. The principle is to use compressed air to disperse the lubricating oil into a mist through the nozzle, blow it to the open gear tooth surface and evenly spread it. The advantage is that the lubricating oil applied at any time is the best quality, and each The amount of secondary oil is small, which undoubtedly provides a reliable guarantee for the safe operation of equipment, especially large equipment.
