Mission device null for coaxial reciprocal revolution farming machine

摘要

PROBLEM TO BE SOLVED: To provide a transmission device capable of reducing its cost by installing a reserve bearing seat in advance to make right and left half case bodies a same shape. ;SOLUTION: This transmission device for a coaxial forward and reverse rotating plower is provided by forming a bearing seat 68S as a reserve for the second middle shaft for a right half case body in the vicinity of a bearing seat 67 of the first middle shaft, also a bearing seat 67S as the reserve for the first middle shaft for a right half case body in the vicinity of a bearing seat 68 of the second middle shaft in a left half body base 64L, and a similar constitution in a right half case body base. It is possible to make the left half case and the right half case bodies a same shape, and as a result, since the number of design drawings is reduced to a half and the number of molds are also reduced to a half, it is possible to aim the wide reduction of its cost.;COPYRIGHT: (C)1997,JPO
