For gear lubrication, the mounting position of the nozzle must be calculated to determine the optimum working position. In general, under the standard air source pressure (5 ~ 7MPa), the distance between the nozzle and the outer pitch circle of the lubrication gear is preferably set at 200mm. The angle of incidence of the nozzle to the tooth surface is preferably within 30° of the front of the meshing portion and is selectable within 120° of the front of the meshing portion.
See the location of the single gear drive oil lubrication device. The best position shown in the figure, suitable for low speed operation, ensures that the entire ring gear covers the lubricant in one injection interval. Of course, it is also possible to inject the pinion gear. The installation of the double gear transmission fuel lubrication device can refer to the single gear transmission system. The principle is generally to ensure that the tooth surface is fully lubricated and a small amount of oil droplets drip. Generally, the lubrication of the pinion and the injection of the large ring gear have similar effects.
In the centralized system installation centralized system, the installation of each spray plate is no different from the stand-alone system, and the piping and control lines are arranged. Inspection of fuel injection effect Although the fuel injection device is automatically controlled, regular inspection of the atomization state is also essential for maintenance work. For the convenience of regular inspection, several types of fuel injection devices should be designed with inspection holes. Even if the equipment is in operation, the fuel injection device can be conveniently and safely opened to check the spray atomization condition.
After the adjustment and commissioning equipment is installed, the test operation shall be carried out. At this stage, the following principles shall be observed. The injection time shall ensure that each lubrication belt of the gear is fully lubricated in each lubrication cycle. According to experience, when the injection time is twice the gear rotation period, the lubricating oil film is formed well. Suggestions for improvement of the domestic fuel injection lubrication system. At present, the existing domestic fuel lubrication system can basically meet the production requirements, but due to the domestic use of lubricating oil. The quality difference is large, which causes the nozzle to be clogged during the use of such equipment, which increases the maintenance of the equipment. Therefore, solving the general adaptability of the oil-injection lubrication equipment to the oil product and reducing the clogging of the nozzle are the problems that should be solved in the next stage of research and development of such products.
