Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe wholely.
Shown in Fig. 1 and 2, a kind of energy-saving and high-pressure Roots blower, including cylinder body 1, cylinder body 1 side is provided with Driving terminal 2 He
Driving fuel tank 4, opposite side is sequentially provided with driven end cap 3 and driven fuel tank 6；It is provided with an active impeller axle 7 and through this cylinder body 1
Driven impeller axle 6, the afterbody of described active impeller axle 7 be provided with drive this active impeller axle 7 rotation driving gear 9, described from
Movable vane wheel shaft 6 afterbody is provided with the driven gear 10 driving this driven impeller axle 6 to rotate；Described active impeller axle 7 and described driving
End cap 2 junction is provided with a spring bearing 19；Described impeller axle (6,7) is provided with machinery fan with the joint portion of described end cap (2,3)
Palace seals.
Described mechanical labyrinth seals and includes that a seal receptacle 11 and is located at the piston ring seat 13 below seal receptacle 11, described work
The outer surface of plug ring seat 13 is provided with annular groove, is provided with elastic piston ring 12 in described annular groove；Described active impeller axle 7 end and institute
State driven impeller axle 6 end and be equipped with a driven end bearing 18；Described active impeller axle 7 afterbody and described driven impeller axle 6 tail
Portion is equipped with drive end bearing 17 and an oil scraper ring 14；It is provided with wavy spring between driven end bearing 18 and impeller axle (6,7)
8；Actively impeller axle 7 afterbody and end, the end of described driven impeller axle 6 are equipped with a disc 20；The tail of driven impeller axle 6
Portion is provided with an impeller clearance adjusting apparatus, and this device includes the U-shaped lid 16 being buckled in driven impeller axle 6 tail end and a bolt
15, described U-shaped lid 16 is fixing with bolt 15 to be connected, and can drive U-shaped lid 16 transverse shifting when bolt 15 rotates.
As illustrated in fig. 1 and 2, present invention employs five bearing arrangements, stretch out one in active impeller axle 7 tail end (drive end)
Spring bearing 19.General Roots blower uses four bearing arrangements, is respectively arranged with two at the two ends of two impeller axles (6,7)
Bearing supports, totally four bearings, and the cantilever of its actively impeller axle 7 drive end is longer, and cantilever is the longest more easily produces flexure, and with
The increase of jib-length, the impact on amount of deflection is gradually incremented by, and its excessive amount of deflection not only affects the precision of transmission, has an effect on tooth
The bearing capacity of wheel, will cause the vibration of fierceness at high speeds.Aerator of the present invention shortens active impeller axle 7 drive end
Jib-length, reduces amount of deflection, improves the rigidity of actively impeller axle 7 so that transmission is more steadily reliable, decreases friction and produces
Heat, make Roots blower can obtain higher pressure.Transmission the most smoothly, reduces energy loss, has saved energy
Source.Spring bearing 19 improves the force-bearing situation of bearing of blower, gear simultaneously, improves the bearing capacity of aerator, extends
Bearing of blower, the service life of gear, reduce use cost；The present invention improves sealing structure, prevents letting out of gases at high pressure
Dew, general Roots blower does not has sealing gland or uses the simplest oil sealing, to avoid the lubricating oil in fuel tank not enter in cylinder body 1
Chamber.The present invention adds mechanical labyrinth in end cap (2,3) inner side and seals, including seal receptacle 11, elastic piston ring 12 and piston ring
Seat 13.Annular groove, elastic piston ring 12 is had to be arranged in piston ring seat 13 annular groove on the outer surface of piston ring seat 13, elastic piston ring
The elastic reaction of 12, makes elastic piston ring 12 outer ring be close on the inwall of end cap (2,3) inner ring, prevents gas from impeller axle
Gap between (6,7) outer ring and end cap (2,3) inner ring leaks out, good sealing effect, it is ensured that gas is not from cylinder body 1 inner chamber
Leak into the fuel tank (4,5) in end cap (2,3) outside, thus obtain higher use pressure；Invention increases disc 20.Fortune
During Zhuaning, by the effect of disc 20, the lubricating oil making fuel tank (4,5) bottom can be to the tooth on upper leaf wheel shaft (6,7)
Wheel (9,10) and bearing (17,18) sufficient lubrication, improve the lubrication heat-sinking capability of aerator, reduces the temperature of aerator, extends
Bearing of blower (17,18), the service life of gear (9,10).Simultaneously between bearing (17,18) and mechanical labyrinth seal
It is mounted with oil scraper ring 14, can effectively stop lubricating oil to enter aerator cylinder body 1 inner chamber, it is ensured that the air cleaner of conveying, it is achieved nothing
Oil conveying.
Multiple amendment to these embodiments will be apparent from, herein for those skilled in the art
Defined General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.
