The promising connection part that prevents of the joint welding of the shell of above-mentioned band gear ring and lower contact and upper connection produces the locking steel plate that moves.
Above saidly be fixed on the input shaft with key in order to the whole centrifugal equilibrium of forces iron on the balance eccentric journal.
Above said compound planet gear, band gear ring shell and and the output shaft of band small gear all adopt the manufacturing of resistant to elevated temperatures high-strength stainless heat-resisting steel material, and heat-treat according to material requirements; The output shaft of the shell of compound planet gear, band gear ring and band small gear all increases the nitrocarburizing of wear-resisting property to be handled.
Superiority of the present utility model is: 1, this oil-immersed pump speed reducer can use well depth greater than 1000 meters deep-well in, and can under the high temperature of 100 ℃-200 ℃ of ambient temperatures and borehole pressure be steady running under the high pressure more than 10 MPas; 2, other any speed reducers of this speed reducer volume ratio are little, and transmission power is big, running steadily, the efficient height, the life-span is long, overload capacity and heat-resisting, wear resistance all are better than other like product; 3, simple and compact for structure, cost of production is relatively low, and is practical, and powerful DEVELOPMENT PROSPECT is arranged.
(4) description of drawings:
Accompanying drawing is that the master of the related a kind of oil-immersed pump special reduction gear of the utility model cuts open figure.
Wherein: 1 is compound planet gear, and 1a is the small gear on the compound planet gear, and 1b is the ring gear on the compound planet gear, 2 is bearing I, and 3 is eccentric journal, and 4 is balance iron, 5 is input shaft, and 6 is the body lower contact, and 7 is bearing I I, 8 is the O RunddichtringO, and 9 is shell, and 9a is the fixed gear ring in the shell, 10 is bearing I II, and 11 is the small gear on the output shaft 12, and 12 is output shaft, 13 is bearing I V, and 14 is the body upper connection, and 15 is locking steel plate.
(5) embodiment:
Embodiment: a kind of oil-immersed pump special reduction gear (seeing accompanying drawing) is characterized in that it is to be made of compound planet gear 1, input shaft 5, output shaft 12, bearing and other relevant part; Said compound planet gear 1 is installed on by bearing I 2 on the eccentric journal 3 of input shaft 5, and input shaft 5 lower ends are installed on bearing I I7 in the lower contact 6 of body, and its upper end is installed in the hole of small gear 11 of output shaft 12 lower ends with bearing I II10; The 9a engagement mutually of fixed gear ring on the small gear 1a of compound planet gear 1 lower end and the shell 9, simultaneously the ring gear 1b of duplicate gear 1 upper end is meshed with the small gear 11 of output shaft 12 lower ends again, overlaps bearing IV13 as deceleration output shaft 12 usefulness two of output and is installed in the body upper connection 14; Also be equipped with one on the input shaft 5 in order to the whole centrifugal equilibrium of forces iron 4 on the balance eccentric journal 3; Shell 9 is made an integral body with fixed gear ring 9a in it, and the shell 9 of band gear ring 9a is threaded integral body with lower contact 6 and upper connection 14 usefulness, and the joint O RunddichtringO 8 that has docking port to seal; Said pitch wheel closes: the small gear 1a of compound planet gear 1 lower end adopts 40 teeth, fixed gear ring 9a on the shell 9 that is meshed with it adopts 42 teeth, the ring gear 1b of compound planet gear 1 upper end adopts 34 teeth, and pinion in mesh 11 adopts 32 teeth with it; All gears all adopt the short tooth profiles of tooth that modulus is 2.75, tooth-shape angle is 20 degree to design.
The shell 9 of above-mentioned band gear ring 9a produces the locking steel plate 15 that moves with the promising connection part that prevents of the joint welding of lower contact 6 and upper connection 14.
Above saidly be fixed on the input shaft 5 with key in order to the whole centrifugal equilibrium of forces iron 4 on the balance eccentric journal 3.
Above said compound planet gear 1, band gear ring 9a shell 9 and and the output shaft 12 of band small gear 11 all adopt the manufacturing of resistant to elevated temperatures high-strength stainless heat-resisting steel material, and heat-treat according to material requirements; The shell 9 of compound planet gear 1, band gear ring 9a and the output shaft 12 of band small gear 11 all increase the nitrocarburizing of wear-resisting property to be handled.
Transmission principle of the present utility model is: when input shaft 5 is pressed the motor speed rotation, because the effect of eccentric journal 3, make the small gear 1a of compound planet gear 1 lower end in the fixed gear ring 9a of shell 9, do the planetary motion that existing revolution has rotation again, this planetary motion drives small gear 11 rotations of output shaft 12 lower ends again by the ring gear 1b of compound planet gear 1 upper end, output shaft 12 can be with the output of the rotating speed after slowing down, pass to next stage mechanism, simultaneously moment of torsion is amplified, finish gearing down, realize the transmission purpose of speed reducer; In addition, because eccentric journal 3, bearing I 2 and compound planet gear 1 on the input shaft 5 are together, in high speed rotating, can produce sizable centrifugal force, cause speed reducer to produce vibrations, therefore the centrifugal force that produces in the time of must coming eccentric mass on the balance input shaft in high speed rotating by the opposite centrifugal force of equal and opposite in direction, direction that the eccentric mass of balance iron 4 produces when the high speed rotating makes the speed reducer can smooth operation.This speed reducer uses the power input that can be used as screw pump in oil well to use.This case must be in addition by output mechanism, and difficulty of processing reduces significantly, thereby accomplishes the end in view.
