bearing lubrication methods introduced 4
1, oil ring lubrication: lubrication only way for the horizontal axis. By hanging in the shaft and can rotate the ring to the oil pool oil into the bearing. Applicable to medium-speed shaft diameter greater than 50mm and high-speed bearings. Oil ring preferably seamless, bearing wide-diameter ratio less than 2, may use only one oil ring, Otherwise required two oil ring.
2 Lubrication: from the container through holes, pins, valve oil supply roughly quantitative, the most classic is the oil drip cup. Drop of oil increased with the oil viscosity, bearing clearance and oil supply holes in different positions have changed significantly. For the circumferential speed of less than 4 ~ 5m / s and contains light-load bearing.
3, oil bath lubrication: part of the bearing in the lubrication oil immersion method. This method commonly used in the vertical axis of the thrust bearing, and should not be used for horizontal shaft radial bearings.
4, the oil cushion lubrication: The oil pad by capillary action, the oil pool oil coating to the surface of shaft. This method enables the friction surface be kept clean, but dust will plug the pores caused by insufficient oil supply. Oil cushion lubrication oil lubrication oil supply is usually only 1 / 20.
bearings Clean Heat Treatment:
The use of waste heat burner has reached a high level, bearing burner mix and air - fuel ratio of strict control to ensure a reasonable premise of combustion, so that bearing NOX and CO decreased to a minimum; use of gas carburizing, carbonitriding and vacuum heat treatment technology to reduce waste treatment alternative to salt bath containing salt and CN-are toxic contamination of water sources; using synthetic water-soluble quenching oil to replace part of the quenching oil, used vegetable oil instead of part of biodegradable mineral oil to reduce oil pollution.
bearing formation of heat production wastewater, waste gas, waste salt, dust, noise and electromagnetic radiation Dengjun causes environmental pollution.
Solution heat treatment of environmental pollution, the implementation of clean heat treatment (heat treatment, or green) is the developed countries, the developing direction of heat treatment technology. In order to reduce SO2, CO, CO2, coal dust and emissions, bearing has basically put an end to the use of coal as fuel, heavy fuel oil use less and less, instead of mostly light oil, natural gas remains the most desirable fuel.
