Worm gear and worm gear lubrication common three questions

Worm gear and worm gear lubrication common 2019 - three questions 10 - 23 worm gear and worm gear box are common in industrial production, and other gear reducer, good lubrication is one of the most important aspects of the gear box and maintenance. For worm gear and worm gear, lubrication problems mainly has three aspects: lack of oil, lubrication, gear oil, improper choice. 1, lack of lack of lubricating oil, can cause the dry friction occurs while the worm gear and worm, and the dry friction causes the worm and worm wheel wear. In use, these circumstances are prone to dry friction, low temperature cold start, oil shortage, not timely to add, leak lead to lack of oil, or even forget to cheer when installation, and so on. Low temperature, the gear oil viscosity increases even stops flowing, inadequate lubrication gear, therefore, should consider when choosing gear oil winter minimum temperature, to ensure that the gear oil at low temperature has good liquidity. Use the add gear oil from time to time and keep the oil in a suitable range. There is a kind of situation can cause lack of oil although less common, but also should pay attention. After gear box in the process of transportation, often didn't add gear oil, on the one hand, because of gas increase the weight, especially a large quantity of oil gear box. Followed by the convenience of users, users receive after gear box, add gear oil, if the original additive gear oil, lubricating oil mixed may occur, and the different gear oil should not be mixed. But when installing a worm gear and worm gear box, does someone forgot to add lubricant, especially new employees, if not peered at the tag or install prompts, employees may not really go start the gear box. If lack of oil, worm gear and worm will soon wear, especially the copper on the worm gear. Even if later found that the addition of gear oil, the damage is irreparable. 2, insufficient lubrication gear oil oil, or installed, can cause worm gear and worm insufficient lubrication. Worm gear and worm in the installation, most of the time is the worm gear, worm in; Sometimes it is the opposite. Note that in both cases, the gear oil level requirement is different, if it is worm gear, worm at the bottom, need the gear oil oil amount more than the worm gear next. When the worm gear on, therefore, must pay attention to increase the oil gear oil, otherwise it will cause the worm and worm wheel lubrication, dry friction output shaft is short of oil. In use, inadequate lubrication is often overlooked, after a period of time, found the gearbox fault. In some cases, staff have no relate with insufficient lubrication of the gearbox fault. Therefore, when installing a worm gear and worm, should according to the installation, in the form of the gear oil in the oil quantity adjusting, avoid insufficient lubrication, in the case of worm in next, pay special attention to. Incorrect 3, worm gear and worm gear oil equipment manufacturer will give you the selection of gear oil, including gear oil viscosity grade, type, suitable for oil, and other oil. Users in the selection of gear oil, should according to the manufacturer's recommendations, and connecting with the actual use of temperature ( High temperature, low temperature) And load conditions, choose appropriate gear oil. Choosing gear oil, to choose the appropriate ISO viscosity grade. Viscosity is too big, in the operation of the gear box will be fever, increase energy consumption. Viscosity is too small, gear oil in the oil film strength is insufficient, will cause the gear wear and tear, so choice should follow the principle of suitable viscosity. Generally speaking, the worm gear and worm worm gear tooth using copper, and the worm made from steel. Suitable for worm gear and worm gear oil, the most common is compound gear oil, this kind of gear oil additive added fat, provide sliding between the worm gear and worm gear lubrication, reduce friction between tooth surfaces. Select extreme pressure gear oil ( EP) , attention should be paid to some extreme pressure gear oil containing active sulphur or active chlorine extreme pressure agent, copper of worm gear tooth can cause corrosion, shorten the service life of gear, so should avoid to use this kind of extreme pressure gear oil. （ Source: shun yi industrial integration service provider)
