To improve the performance of DBY280-22.4-II gear reducer, you can start by selecting the appropriate lubricant, determining the lubrication method, controlling the oil quantity, and regularly maintaining. The specific lubrication methods are as follows:
Choose the right lubricant : choose according to the use conditions, workload and speed of the reducer. It is recommended to use lubricating oil or grease with good adhesion, extreme pressure and wear resistance. If the reducer is in a high temperature environment, lubricating oil with good thermal stability is required; in humid environments, lubricating oil with good rust resistance and emulsification resistance should be selected.
Determine the lubrication method : If the gear circumferential speed is greater than 12m/s, oil injection lubrication can be used. Oil is supplied at a certain pressure through an oil pump or a central oil supply station, and lubricating oil is sprayed onto the meshing surface of the gear teeth using the nozzle, and the nozzle position is determined according to the circumferential speed of the gear. If the circumferential speed of the gear is less than 12m/s, it is suitable to use oil immersion lubrication. Immerse the gear teeth of the large gear into the oil pool. When the gear is driven, bring the lubricating oil to the meshing tooth surface. At the same time, use the oil to flutter the oil to dissipate heat. Pay attention to the moderate depth of the gear immersed in the oil.
Control oil volume : The amount of oil in the oil pool must be determined based on the power transmitted by the gears. Generally speaking, for every 1kW of power transmitted by a single-stage transmission, the oil demand is about 0.35L-0.7L, and the oil demand for multi-stage transmission increases exponentially by stage. Too much oil will increase stirring loss and heating, and too little will lead to insufficient lubrication, which may affect the lubrication effect and even cause failure.
Regular inspection and replacement : Check the quality and quantity of lubricant regularly to see if the lubricant is clean and free of impurities. If the oil becomes darker, the viscosity changes or there is a peculiar smell, etc., it may be that the oil is aging or contaminated, and it should be replaced in time. At the same time, it is necessary to ensure that the oil level is within the normal range and replenish lubricating oil in a timely manner. It is also necessary to check the operating status of the lubrication system to ensure that the oil pump, nozzle and other components work normally.
Pay attention to cleaning and protection : Keep the reducer clean to prevent dust, impurities and other pollutants from entering the lubrication system. For open or semi-open gear reducers, dirt and impurities on the gear surface should be regularly cleaned to ensure lubrication.
