Series null of the gearbox which adopts inscribed gearing epicyclic gear structure

摘要

PURPOSE: To actualize those of being lighter in weight, compact in size and high steeliness as well as to make multifarious combinations easily obtainable at the time of promoting a series of reduction gears adopted with an internal meshing planetary gear structure. ;CONSTITUTION: A reduction gear mechanism part is supported inboard on a casing 112 via a pair of bearings 115a and 114b, while a range of up to these paired bearings 115a, 115b is set to a reduction gear part pack F and unitized as one body. In addition, this reduction gear part pack F is housed in an internal gear 110 and, in turn, this internal gear 110 is unified with the casing 112, and further a planetary gear structural part D or E, inclusive of an output shaft cover too, are unitized. Likewise, those of input side portions A1, A2, B and C are also unitized respectively, and at the same frame number, respective ones are made so as to be optionally combined together via a joint spline 200.;COPYRIGHT: (C)1994,JPO&Japio
