Planetary Gear

AIM:- Designing of the Planetary Gear and its motion analysis.

components required:-

1.Carrier

2.Ring gear :-

module : 2.5,pitch diameter:115 , no.of teeteh :46

3.sun/centre gear :-

module : 2.5,pitch diameter:35 , no.of teeteh :14

4.planet gear :-

module : 2.5,pitch diameter:40 , no.of teeteh :16

CALCULATION OF THE DIA.OF PLANET GEAR USING FORMULA:

radius of ring gear = dia.of planet gear + radius of sun gear.

CALCULATION OF NO.TEETH OF PLANET GEAR.

T = d/m , where , T = no.of teeth ,d= pitch diameter,m = module (i.e.2.5)

These all componets of imported directly in the assembly.

• Design library > Toolbox >ANSI metric > power transmission> gear for sun and planet gear :- select (spure gear) & gear for ring gear:- select(Internal spure gear)

The motion analysis is done on the basis of :

input speed of 200 rpm .
