Abstract
The utility model discloses a cycloidal planetary speed reducer, comprising an input shaft, an output shaft, an epicycloidal wheel, a hypocycloid wheel, a housing and a rolling body. The utility model is characterized in that a holder of the rolling body is arranged on an eccentric wheel of the input shaft via a bearing; the rolling body is uniformly arranged on the holder of the rolling body; the epicycloidal wheel is connected with an output shaft via a connecting disk. The utility model has the advantage that the utility model has convenient assembly, and prevents the rolling body from shifting or sliding out.
Description
The utility model relates to a kind of retarder, particularly the cycloid in planet retarder.
General cycloid in planet retarder generally adopts two epicyclodial wheels to be installed on the eccentric bushing of input shaft at present, adopts the pin axle type output mechanism, is sliding friction between epicyclodial wheel and the pinwheel, and the rotary arm bearing of this retarder is stressed bigger, influences transmission efficiency.There was the people to propose new design (seeing that China Patent No. is 89210535.6 patent documentation) in 1989, the main points of this design are that two epicycloid planet wheels are made one, adopt inside and outside cycloid wheel to replace the pin axle type output mechanism by the output mechanism that rolling element is meshed, though this retarder has reduced volume, changing sliding friction is rolling friction, but because rolling element does not have fixing device, both increased the difficulty of assembling, and in operation process, especially under big load, can cause rolling element displacement or skid off, influence transmission efficiency.
The purpose of this utility model is to provide a kind of not only can prevent the cycloid in planet retarder that rolling element moves or skids off but also is convenient to assemble.
The purpose of this utility model be achieved in that epicyclodial wheel by Bearing Installation on the eccentric wheel of input shaft, the hypocycloid wheel is installed on the housing, epicyclodial wheel is meshed with the hypocycloid wheel by rolling element, technological points of the present utility model be have a roller holder by Bearing Installation on the eccentric wheel of input shaft, rolling element evenly is installed on the roller holder, and epicyclodial wheel is connected with output shaft by land.
The utility model is owing to installed roller holder, and rolling element evenly is installed on the roller holder, has so not only prevented the rolling element displacement or skids off, and keeps the stability of velocity ratio, and assembles simple and easy to doly, is suitable for producing in batches.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cut-away view of A-A among Fig. 1.
Referring to Fig. 1 and Fig. 2, epicyclodial wheel 6 is installed in by bearing 9 on the eccentric wheel 1 of input shaft 2, and hypocycloid wheel 10 is installed on the housing 12, and epicyclodial wheel 6 is meshed with hypocycloid wheel 10 by rolling element 5.Roller holder 11 is installed on the eccentric wheel 1 of input shaft 2 by bearing 13.The offset of epicyclodial wheel 6 is 2 times of offset of roller holder 11, and promptly the offset of epicyclodial wheel 6 is 2e, and the offset of roller holder 11 is e, and both eccentric directions are identical.Rolling element 5 evenly is installed on the roller holder 11, and in this example, rolling element 5 is a cylindrical roller, and this roller is installed on the roller holder 11 by roller pin 4.Many 2 of the number of teeth of the gear ratio epicyclodial wheel 6 of hypocycloid wheel 10, the quantity of rolling element 5 is Duoed 1 than the number of teeth of epicyclodial wheel 6.Epicyclodial wheel 6 is connected with output shaft 7 by land 8.For keeping the running balance, on input shaft 2, be provided with an equilibrium block 3.
Claims (4)
