Abstract
The utility model relates to a cycloid pin gear planetary reducer. The cantilevered end of an output mechanism of the cycloid pin gear planetary reducer is particularly provided with a uniform load plate, and the end of the uniform load plate is provided with a fastening ring as an auxiliary support point. Therefore, the force bearing conditions of the component mechanism can be changed significantly, the problems of serious deformation and easy wearing of major parts caused by non-uniform force bearing of the mechanism and corresponding impact on the service life of the reducer can be solved, and the service life of the reducer can be prolonged. The reducer is suitable for extensive applications in large lifting machinery of ports and other heavy mechanical products.
Description
Technical field
The utility model relates to a kind of cycloid pin tooth planetary speed reducer, through special design, changes the output mechanism force-bearing situation, reduces distortion, prolongs this speed reducer working life, makes it suit in large-scale hoisting machineries such as harbour facilities, to use.
Background technique
Existing cycloid pin tooth planetary speed reducer is particularly exported the speed reducer of high pulling torque, and the output mechanism discontinuity makes the distortion of main part in addition, and easy abrasion has influenced working life of speed reducer.
Summary of the invention
The purpose of the utility model is: a kind of newly-designed cycloid pin tooth planetary speed reducer is provided; The special design of the cantilever end of its output mechanism has been installed additional and has all been carried part; And at its end installation aiding support point; Changed this mechanism's force-bearing situation, solved, influenced the speed reducer problem in working life because of this mechanism's stress deformation.
The utility model is achieved in that a kind of cycloid pin tooth planetary speed reducer, and it is made up of pin wheel housing, cycloid wheel, eccentric bushing, pin tooth, spacer ring, guide, rear end cover, bearing pin, bearing, back-up ring, output shaft, oil sealing, retaining ring, locating stud, setting sleeve, input shaft, front cover, equal load plate etc.Pin wheel housing, front cover and rear end cover are formed the body shell.Input shaft tightens the cover eccentric bushing; The eccentric bushing two ends are supported by pair of bearings; Be bearing in respectively in output shaft and the equal load plate, and output shaft is close to by locating stud, setting sleeve, bearing pin, guide and equal load plate, forms output mechanism; Output shaft is supported by pair of bearings with equal load plate, is bearing in respectively in rear end cover and the front cover.On the eccentric bushing in two eccentric circles and pair of bearings and the cycloid wheel two round-formed holding be connected; Through cycloid wheel profile cycloidal curve and pin tooth cylindrical, the hypocycloidal engagement of pin wheel housing; Form the cycloid speed reducer structure; Cycloid wheel is likened to the deceleration that designs slowly run,, the output shaft low speed high torque is rotated by circle in the cycloid wheel guide, bearing pin, setting sleeve, position pin in output mechanism.
In the said output mechanism, installed equal load plate additional, at left end aiding support point retaining ring has been installed again,, solved the problem of output mechanism stress deformation speed reducer influence in working life to improve the force-bearing situation of output mechanism in the special design of its right cantilever end.
The beneficial effect of the utility model makes the extensive use in a lot of engineering goods such as harbour large-scale hoisting machinery of this deceleration function the working life that can obviously improve cycloid pin tooth planetary speed reducer, and very big economic benefit is arranged.
