The speed reducer comprises an input shaft, an output shaft, an exciter, a bearing, a planetary wheel and a center wheel. The utility model is characterized in that a crankshaft is composed of one planetary wheel and the input shaft; the utility model is additionally provided with a flexible sealing device and a transitioning bearing; a single-piece planet wheel is in erection joint with an accessory shaft; the utility model is provided with a balancing device to ensure the swinging balance of the planetary wheel. The utility model has the advantages of good tightness, and can be used for industry, such as chemical industry, medicine, etc.
Description
The utility model relates to the drive mechanism and the seal arrangement of cycloidal planetary gear speed reducer and planet-gear speed reducer, belongs to field of mechanical technique.
Existing cycloidal planetary gear speed reducer is a dual planetary gear, two planet wheels are separately fixed on the input shaft, input shaft and output shaft all are d-axis, be to install by the off-centre of input shaft and planet wheel, reach and radially wobble, two planet wheels reach balance with respect to input axis symmetry, at the input shaft part mechanical seal or stuffing seal are set.This planetary speed reducer complex structure, sealing effect is poor, has the problem of leaking, befouling environment, the working life of influence machinery, and planet-gear speed reducer, because the same sealing effect, so be subjected to certain limitation in the application of aspects such as chemical industry.
The purpose of this utility model is to provide a kind of simple in structure, and gear ratio is big, the hermetically sealed planetary speed reducer of good seal performance.
The purpose of this utility model is achieved in that hermetically sealed planetary speed reducer, comprise input shaft, output shaft, exciter, bearing, planet wheel, central gear, it is characterized in that speed reducer is provided with flexible seal device, Equilibrator and transition bearing, input shaft is the bent axle that is provided with noncoupled axle, the monolithic planet wheel is set on the noncoupled axle, noncoupled axle opposite on input shaft is provided with Equilibrator, the transition bearing is arranged between exciter and the planet wheel, and the top of flexible seal device, bottom are connected with the saturating lid of flange and exciter respectively.Said planet wheel is cycloid wheel or planetary pinion.Planet wheel, central gear, transition bearing etc. are enclosed in the Seal cage, are isolated from the outside, reach hermetic effect.Flexible seal device is a bellows or by the compound compound seal cover that constitutes that connects of bellows and corrugated plate.Equilibrator is that iron block and coupling constitute.If the planet wheel cycloid wheel then forms the sealing cycloid speed reducer, if the planet wheel planetary pinion then is a planet-gear speed reducer.
The utility model is simple and reasonable, manufactures easily, and cost is low, and gear ratio is big, and good sealing effect can be widely used in industries such as chemical industry, medical science.
Accompanying drawing is a structural representation of the present utility model, among the figure 1 flexible seal device, 2 input shafts, 3 cover thoroughly, 4 central gears, 5 planet wheels, 6 covers, 7 bearing pins, 8 exciters, 9 output shafts, 10 bearings, 11 transition bearings, 12 flanges.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
Noncoupled axle is established in lower end at input shaft, the axis parallel of the shaft axis of noncoupled axle and input shaft, output shaft.Noncoupled axle is connected with exciter by bearing, exciter is connected with the monolithic planet wheel by the transition bearing, establishing bearing pin between planet wheel and the output shaft is connected, the Equilibrator that is made of iron block and link is set on input shaft, iron block is on the opposite of noncoupled axle, and the center of gravity line of iron block and input shaft axis and attached shaft axis are in a plane.With bellows and the compounded compound seal cover of corrugated plate is flexible seal device, and the upper end of compound seal cover is connected with flange, and the lower end is connected with the saturating lid of exciter.
