" Eleventh-Five Year Plan " New Countryside Construction of formulating at current project of South-to-North water diversion and country, transform new rural area, greatly develop the agriculture cause of China.Many hydraulic engineerings obtain building and technical innovation, main transmission epicyclic gearbox as the key equipment bidirectional submersed three-flow pump of hydraulic engineering construction is able to a large amount of being used, the utilization of epicyclic gearbox in submersible pump can reduce the investment of whole hydraulic engineering greatly, and along with China's gear-box manufacturing industry develops on an unprecedented scale, the gear-box manufacturing technology is increasingly mature, material property improves day by day, design level is gradually improved, can not only design high performance speed reducer, also can produce the gear-box of diving with high-performance, high-reliability.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of compact structure, reliable, good concentricity, the sensitivity of floating and the good planetary gear box specially for great power bidirectional submersed three-flow pump of load are provided.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: planetary gear box specially for great power bidirectional submersed three-flow pump, the body that comprises the saturating lid of saturating lid and back before being fitted with, the technical measures of taking also comprise: body is the overall structure that front and back are equipped with flange, and forward flange connects with motor, rear flange connects with the pump main body, internal body is equipped with ring gear, all connects by screw and gib headed key; Body is fitted with sun gear, planet wheel, planet carrier; Input shaft, planet carrier, sun gear, output shaft concentric, input shaft one end is hollow internal tooth casing, the other end connects with sun gear by the unsteady tooth cover of crowned teeth, planet carrier is installed on body and the bearing support by fore bearing and rear bearing, one end of planet carrier projecting shaft bearing is an output shaft, and this output shaft is the involute splines cover; The normal engagement that uniform three planet wheels of planet carrier periphery, planet wheel guarantee identical meshing backlass with corresponding ring gear and sun gear respectively.
The concrete technical measures of taking also comprise: planet wheel by Bearing Installation on the uniform planet axis of planet carrier periphery.Temperature transducer is installed on the ring gear.Oil sealing all is housed between output shaft and the bearing support.Oil sealing is an outside framework oil seal.The fore bearing and the rear bearing that are used to install planet wheel on the planet carrier are roller bearing.
Compared with prior art, advantage of the present invention is: output stage adopts involute splines to connect can eliminate the decentraction that produces because of manufacturing, input end adopts the crowned teeth splined, can strengthen the unsteady effect of sun gear like this, sun gear and each planet wheel are all carried, thereby improved the bearing capacity of complete machine; Axially locate between sun gear and the planet carrier, thereby sun gear is still unsteady sensitive under the low speed situation, also reaches carrying evenly by ball bearing; Complete machine is to be the special-purpose planetary speed reducer of the diving of the supporting design of bidirectional submersed three-flow pump, and this speed reducer is seven to eight meters dark work under water, and environment and operating mode are abominable, require the design output torque big, the overload capacity height.
Description of drawings
Fig. 1 is the general assembly cross-sectional schematic of the embodiment of the invention;
Fig. 2 is the assembling schematic representation that Fig. 1 left side is looked.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1, shown in Figure 2,1, input shaft, 2, sun gear, 3, preceding lid, 4, fore bearing, 5, body, 6, planet carrier, 7, gib headed key, 8, ring gear, 9, planet wheel, 10, planet axis, 11, bearing support, 12, after lid thoroughly, 13, rear bearing, 14, oil sealing, 15, temperature transducer.
Specific embodiments of the invention, planetary gear box specially for great power bidirectional submersed three-flow pump, the body 5 that comprises the saturating lid 12 of saturating lid 3 and back before being fitted with, body 5 is the overall structure that front and back are equipped with flange, and forward flange connects with motor, rear flange connects with the pump main body, and internal body is equipped with ring gear 8, all connects by screw and gib headed key 7; Body 5 is fitted with sun gear 2, planet wheel 9, planet carrier 6; Input shaft 1, planet carrier 6, sun gear 2, output shaft concentric, input shaft 1 one ends are hollow internal tooth casing, the other end connects with sun gear 2 by the unsteady tooth cover of crowned teeth, planet carrier 6 is installed on body 5 and the bearing support 11 by fore bearing 4 and rear bearing 13, one end of planet carrier 6 projecting shaft bearings 11 is an output shaft, and this output shaft is the involute splines cover; The normal engagement that uniform three planet wheels 9 of planet carrier 6 periphery, planet wheel 9 guarantee identical meshing backlass with corresponding ring gear 8 and sun gear 2 respectively.Planet wheel 9 by Bearing Installation on the uniform planet axis 10 of planet carrier 6 periphery.Temperature transducer 15 is installed on the ring gear 8.Between output shaft and the bearing support 11 oil sealing 14 is housed all.Oil sealing 14 is an outside framework oil seal.The fore bearing 4 and the rear bearing 13 that are used to install planet wheel 9 on the planet carrier 6 are roller bearing.
Advantage of the present invention is: the inner temperature transducer of installing can monitor the temperature variation of gear-box under water on the ground; Output stage adopts involute splines to connect can eliminate the decentraction that produces because of manufacturing, and input end adopts the crowned teeth splined, can strengthen the unsteady effect of sun gear like this, sun gear and each planet wheel is all carried, thereby improved the bearing capacity of complete machine.Axially locate between sun gear and the planet carrier, thereby sun gear is still unsteady sensitive under the low speed situation, also reaches carrying evenly by ball bearing; Complete machine is to be the special-purpose planetary speed reducer of the diving of the supporting design of bidirectional submersed three-flow pump, and this speed reducer is seven or eight meters dark work under water, and environment and operating mode are abominable, require the design output torque big, the overload capacity height.The special-purpose planetary speed reducer configuration design smoothness of bidirectional submersed three-flow pump is attractive in appearance, with whole submersible pump one integrated mass, the internal structure compact and reasonable, bring into play the carrying advantage of planetary speed reducer to greatest extent, in conjunction with up-to-date manufacturing technology process and the leading new material that adopts, make the bearing capacity of this planetary speed reducer reach 2.5 times of common epicyclic gearbox of same specification size.
