Abstract
The utility model discloses a large speed ratio planetary speed reducer free from planetary bearings. The speed reducing ratio of single stage is 10; 600. The large speed ratio planetary speed reducer free from planetary bearings aims to replace a cycloidal pin-wheel speed reducer and a worm reducer and becomes a universal and systematic reducer. The utility model has the advantages of simple structure, easy manufacturing, higher efficiency, small size, high strength, low cost, small size and low noise. The large speed ratio planetary speed reducer free from planetary bearings is mainly characterized in that the reducer is free from planetary bearings. The utility model is suitable for various machines, in particular to the speed reducing ratio of single stage being 87; 600 of large strength situation. For example, the large speed ratio planetary speed reducer free from planetary bearings replaces a cycloidal pin-wheel speed reducer and the cost can be reduced more than 20%.
Description
It is the planetary speed reducer of 10-600 that the utility model belongs to single-stage reduction speed ratio general in the engineering part.
What the present various countries use of large speed ratio planetary speed reducer was maximum is the cycloidal planetary gear speed reducer of few tooth differential, and the existing shortcoming of this machine is: planetary shaft strength is very big; Output mechanism is cantilever mast Xiao, often becomes the weak link of complete machine; Input shaft is two eccentric so dynamic unbalance produces vibration and noise when rotating speed is high; Material therefor requires very high, adopts Bearing Steel in a large number; The heat treatment requirements height; A large amount of parts need grinding, and requirement on machining accuracy is very high, single-stage speed ratio 11-87, and surpassing 87 promptly must double reduction; Because planet wheel is cycloid wheel and milling machine that must be special-purpose, grinding machine and can not use gear hobbing, the gear shaping machine that generally has, when producing in serial form, when gear ratio change, pinwheel number and cycloidal gear number average change thereupon, make processed complexization.
The purpose of this utility model is a kind of involute profile of design; Adopt the common shaping machine that rolls; Speed ratio is wide; Simple in structure; Easy processing, seriation are easy to, material is common cheap; Size is little; Cost is low and the universal seriation speed reducer of greater efficiency arranged.
Structure of the present utility model is shown in Figure of description.(1) is input shaft among the figure, is processed with an external gear above, and its left end frame is held on the end cap (6), and the right-hand member frame is held on the shaft.(2) be casing, be processed with an internal gear above.This internal gear and planet (4) engagement.(3) be supporting ring, it is sleeved on the diameter of axle of planet wheel two ends.(4) be planet wheel, its simultaneously with go into shaftgear and casing on internal gear, the internal gear on the shaft be meshed, quantity is three.(5) be shaft, be processed with an output inner gear above, be held on the casing with two axis of rolling bolsters.When the input shaft high speed rotating, planet crop rotation planetary motion drives shaft simultaneously and does to slowly run.
Characteristics of the present utility model are:
1. the inside and outside of planet wheel all do not have rolling bearing to support, and be simple in structure.
2. planet wheel is a simply connected, easy processing.
3. only use two garden ring bearings outside three planet wheels.
4. number of spare parts is few, easy processing.
5. the complete dynamic balancing of input shaft, vibration, noise is little.
6. because the symmetry properties of structure makes the stressed minimizing of its input shaft and shaft rolling bearing, the life-span increases.
Claims (1)
- A kind of by input shaft (1), casing (2), supporting ring (3), planet wheel (4) has the shaft (5) of output inner gear, and the planetary speed reducer that end cap (6) etc. is formed is characterized in that:1, there is not the rolling bearing supporting inside and outside the planet wheel, but by a pair of garden ring bearing.2, be processed with an output inner gear on the shaft.3, all gears are involute profile.
