9 methods of lubricating commonly used sliding bearings
Author:admin Date:2022-09-14
1 Manual lubricating oil
When it is found that the lubricating oil of the sliding bearing is insufficient, it is the most primitive method to use the oiler to supply oil in time. This method is difficult to maintain a certain amount of oil, and there is a greater risk of forgetting to refuel due to negligence. It is usually only used in light-load, low-speed or intermittent motion occasions. It is best to set a dust cover or a ball valve on the refueling hole, and use felt, cotton, wool, etc. as a filter device.
2 drops point lubrication
A roughly quantitative amount of lubricating oil is supplied from the container through holes, needles, valves, etc. The most classic is the drip oil cup. The amount of oil dripping varies significantly with lubricant viscosity, bearing clearance and oil supply hole location. It is used for light-load and medium-load bearings whose peripheral speed is less than 4～5m/s.
3 oil ring lubrication
Lubrication method for horizontal shafts only. A rotatable ring that hangs on the shaft brings the lubricating oil from the sump to the bearing. Suitable for medium and high speed bearings with shaft diameter greater than 50mm. The oil ring is preferably seamless. When the bearing width-diameter ratio is less than 2, only one oil ring can be used, otherwise two oil rings are required.
4 Oil rope lubrication
The lubricating oil in the oil cup is led into the bearing by the capillary action and siphon action of the oil rope. The oil rope also has a filtering effect.
5 Oil pad lubrication
Use the capillary action of the oil pad to apply the lubricating oil in the oil pool to the surface of the shaft diameter. This method can keep the friction surface clean frequently, but the dust can also block the capillary pores and cause insufficient oil supply. The oil supply of oil pad lubrication is usually only 1/20 of that of oil lubrication.
6 Oil bath lubrication
Lubrication method in which part of the bearing is immersed in lubricating oil. This method is often used for thrust bearings of vertical shafts, and is not suitable for radial bearings of horizontal shafts.
7 Splash Bearings
The lubricating oil splashed by the slap of the rotating parts in the oil tank is supplied to the bearing, which is suitable for the bearing of higher speed.
8 spray lubrication
The lubrication method of atomizing lubricating oil on the friction surface is suitable for high-speed bearings.
9 pressure oil supply lubrication
The oil is supplied to the bearing by the pressure of the lubricating pump, and the lubricating oil flowing from the bearing is recovered to the oil pool for recycling.
