The work process of the present invention and principle
As it is shown in figure 1, the present invention is operationally, motor or other power-equipment drive the power transmission shaft 4 of vertical speed reducer
Rotating, the box bottom of decelerator is equipped with lubricating oil, and lubricating oil floods the lower bearing lubrication hole on the sleeve pipe 9 above lower bearing 3
15 and fuel feed hole 10.Lower bearing 3 is lubricated by lubricating oil by lower bearing lubrication hole 15.When power transmission shaft 4 rotates, lubricating oil leads to
Crossing fuel feed hole 10 and enter the helicla flute 8 on sleeve pipe 9 intermediate solid drive shaft 4, power transmission shaft 4 will enter the profit of helicla flute 8 in rotary course
Lubricating oil pumps into the cavity between upper bearing (metal) 2 and bearing cap 12 by oil storage annular groove 7, main oil gallery 6 and oil outlet 11, the profit in cavity
Upper bearing (metal) 2 is lubricated by lubricating oil.Meanwhile, the lubricating oil via through holes 13 in cavity and oil leak hole 14 flow into travelling gear 5, to biography
Moving gear 5 is lubricated.Lubricating oil after lubricating travelling gear 5 returns to the box bottom of decelerator.
The present invention in the specific implementation, as shown in Figure 1.The lower end cylindrical of power transmission shaft 4 is machined with a plurality of helicla flute 8 He
Article one, annular oil storage annular groove 7, oil storage annular groove 7 communicates with each helicla flute 8, oil storage annular groove 7 and main oil gallery 6 phase in power transmission shaft 4
Logical, it is designed with the oil outlet 11 of a through power transmission shaft of radial direction 4 in the upper end of power transmission shaft 4, during processing main oil gallery 6, by power transmission shaft 4
Holing in top, is blocked in the processing aperture of main oil gallery 6 with screw and sealing gasket the most again；Sleeve pipe 9 is enclosed within power transmission shaft 4
Outside helicla flute 8 and oil storage annular groove 7, sleeve pipe 9 is fixed by screws on lower box, the endoporus of sleeve pipe 9 and helicla flute on power transmission shaft 4
The cylindrical at 8 places coordinates, and fit clearance is 0.01～0.015mm；On the top of vertical speed reducer, bearing cap 12 is solid by screw
Being scheduled on upper box, upper ball cover coordinates the hole on cylindrical to communicate with the through hole 13 on upper box and oil leak hole 14 with upper box.
While power transmission shaft 4 band nutating gear 5 rotates, the lubricating oil in reduction box passes through the oil-in on sleeve pipe 9,
Entering the helicla flute 8 on power transmission shaft 4 cylindrical, under the influence of centrifugal force, the lubricating oil in helicla flute 8 constantly enters into phase therewith
Logical oil storage annular groove 7, under pressure, lubricating oil enters into upper bearing (metal) by the main oil gallery 6 on power transmission shaft 4 and oil outlet 11
Cavity between 2 and bearing cap 12.Lubricating oil in cavity, the upper bearing (metal) 2 on part lubrication vertical speed reducer top, a part
After each movement parts in the through hole 13 on bearing cap 12 and the oil leak hole 14 lubricating transmission gear 5 on casing 1, then flow back to subtract
Circulation lubrication is realized in the oil sump in speed bottom portion.
In the present invention, spiral fluted direction of rotation on power transmission shaft 4 cylindrical, is that the direction of rotation according to power transmission shaft 4 is carried out
Design and Machining, is divided into two kinds of situations: one is power transmission shaft 4 single direction rotation；Two is that power transmission shaft 4 positive and negative alternate rotates.When power transmission shaft 4 is single
To rotation, direction of rotation is that helicla flute 8 is processed into dextrorotation clockwise；Direction of rotation is that counterclockwise helicla flute 8 adds
Work becomes left-handed；When power transmission shaft 4 positive and negative alternate rotates, helicla flute 8 is processed into left-handed or dextrorotation.If power transmission shaft 4 reciprocal crosses
For rotating, then one of them direction of rotation is pump oil operative orientation, and another direction of rotation power transmission shaft 4 does not carry out pump oil work
Making, now, the lubricating oil stored in the cavity between upper bearing (metal) 2 and bearing cap 12 can be continuously in upper bearing (metal) 2 and travelling gear 5
Each movement parts be lubricated, when power transmission shaft 4 reversely rotates, the lubricating oil in cavity is supplemented, makes vertical speed reducer
The purpose of automatic circulation lubrication is all can reach when upper bearing (metal) 2 and travelling gear 5 are unidirectional at power transmission shaft 4 and positive and negative alternate rotates.
