Abstract
The utility model relates to a Roots blower with double oil tanks, which belongs to machinery devices and comprises a drive shaft and a driven shaft, wherein a shaft at one end of the drive shaft and a shaft at one end of the driven shaft are provided with gears which are arranged in the oil tanks, and the other end of the drive shaft and the other end of the driven shaft are driving ends which are also provided with oil tanks; shafts at the driving ends are provided with oil slingers; bearings at both ends of the blower use oil for lubrication, which can improve the lubricated condition of the bearings of the blower and can extend the service life of the bearings so as to cause the Roots blower to be suitable for running in high pressure without using water for cooling for reducing the operation cost. Simultaneously, the utility model is suitable for running at high rotation speed and can improve the volume efficiency and the overall efficiency of the blower.
Description
Technical field
The utility model relates to a kind of root's blower, belongs to mechanical device.
Technical background
Roots blower extensively applies to industrial fields such as environmental protection, electric power, oil, chemical industry, grain conveying.Common Roots blower one step bearing adopts oil lubrication, and the other end adopts grease lubrication, when induced pressure surpasses 0.08Mpa, generally all requires to increase water cooling system, to reduce the fan bearing temperature, prolongs bearing life.The deficiency that common Roots blower exists is: adopt the bearing life of grease lubrication and bearing capacity to be significantly less than the bearing that adopts oil lubrication; The waste that blower fan adopts water cooling to bring water resources.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of suitable higher load pressure is provided and need adopt water-cooled pair of fuel tank Roots blower, its innovative point is fan design is become two fuel tanks, make drive end and gear end bearing all adopt oil lubrication, when blower fan moves in elevated pressures, need not adopt water cooling.Specifically be achieved like this: two fuel tank Roots blowers, comprise driving shaft, driven shaft, on driving shaft and the driven shaft one end axle gear is installed, gear places fuel tank, the other end is a drive end, it is characterized in that drive end also is provided with fuel tank, is equipped with disc on the drive end axle.The blower fan gear end is provided with gear tank, and this step bearing adopts gear to get rid of oil lubrication; The blower fan drive end also is provided with fuel tank, and this step bearing adopts disc to get rid of oil lubrication.
The utility model driving shaft passes drive end fuel tank place and is provided with oil sealing, in case leak-stopping oil.
The two fuel tank Roots blower bearings at both ends of the utility model all adopt oil lubrication, improved the lubricating condition of fan bearing, prolonged bearing life, make Roots blower be fit to the elevated pressures operation, need not adopt water cooling, greatly reduce the operating cost of blower fan, be fit to the operation down of high rotating speed simultaneously, improved the volumetric efficiency and the fan total efficiency of blower fan.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
