Jiangsu Malone empty shaft lubrication solutions
In the hollow shaft portion of the bearing tube mill installed rolling bearing bold diameter, hollow shaft in turn being cooled dilute oil transmitted to the hollow shaft bearing temperature falls within the normal range of 60 ° or less. The advantage of bearing the following areas:
1. superior lubrication for grease, so to minimize bearing friction coefficient, better energy-saving effect.
2. The normal operation of the bearing temperature, than dry oil lubricated bearing temperature is much lower, extending bearing life.
3. Bearing Xiazuo has oil sight oil standard, the operator can always see the oil level is low, be able to replenish fuel, to prevent starvation and poor lubrication, avoid the occurrence of bearing damage accidents.
The oil content of the oil chamber bearing, rolling bearings can be installed outside diameter narrowing (in and out equipment to ensure the installation of adequate strength and torque force premise), hollow shaft and access to materials to set up a spiral tube coupling flange end face, and access to materials spiral tube flange connection. In the hollow shaft from coarse to fine end face, set a compression flange bearing rings to prevent axial bearing sprang.
5. Remove the bearing outer top cover to prevent dust from entering the bearing box, to maintain a good quality oil to ensure that the bearing life, safe and reliable operation.
6. Since the diameter of rolling bearings increased, with an average outside diameter of the hollow shaft diameter difference formation of thin oil lubrication chamber, increase lean oil level, reducing the thin oil spill has received a certain effect.
7. Since the installation of the hollow shaft diameter bold rolling bearing parts of the rolling bearing and the radial distance between the spiral tube out of material increase, played a certain role in cooling insulation. Cooling of the bearing, long life, play a role.
Rolling Block and Rolling Bearing Lubrication medium diameter pipe mill in the cement industry, mining industry, power industry has been widely used. Design and manufacture of rolling bearing housings, most dry oil lubrication. In recent years, the use of situation, because the site operators and oiling work can not be observed in the oil level, can not replenish grease, the grease in the bearing cartridge loading can not be clearly reflected in the emergence of the bearing oil, poor when the phenomenon have occurred, causing light to shorten bearing life, severe damage to the bearing, the need to re-purchase and install new bearings, to bearing manufacturers use a lot of inconvenience and a certain economic losses. To solve this problem, we developed a thin oil lubricated bearing seat of the new technology.
The bearing Xiazuo by two oil chamber and a circulating water chambers, thin oily surface of each oil chamber height position in the inner diameter of the bearing, the oil chamber bottom plane of the floor up to the oil chamber. 1/3 volume of the rolling bearing was immersed in thin oil chamber, thus ensuring a good lubrication of rolling bearings. Intermediate oil chamber is provided with two cooling water circulation jacket body, the oil temperature will be cooled to the cooling water temperature of the bearing fit. This setting, to ensure the needs of bearing lubrication, lubrication does not require the use of complex facilities, stations and other peripherals, do not install the temperature control device, you can achieve safe operation.
In summary, this new hollow shaft with rolling bearing installation forms and methods are based on progress and improve on the original installation method. This new bearing lubrication, lubrication is essential to ensure good bearing.
