Compound planetary gear train planetary gear train with more than one arm r14 t1t3. This method is extremely methodical, which is appropriate since use of trxin is quite futile with an epicyclic gear train such as the following example. Great thanks in advance!
grar Hence the gear ratio has the same meaning as nnptel the simple gear trains. The pitch circle is an imaginary circle that contacts the pitch circle of any other gear with which it is in mesh. No registered users and 9 guests. The nature of the train used depends upon the velocity ratio and the relative position of the axes of shafts. Thus the load inertia may be reduced so much that it is actually less than the motors own inertia j m.
