Document Type and Number:
WIPO Patent Application WO/2014/042064
Kind Code:
A1
Abstract:
This gear transmission is provided with an internal gear, an external gear, a crankshaft and a support member. The crankshaft is supported at both ends by the support member via a pair of first cylindrical roller bearings. The eccentric body of the crankshaft is engaged in a through-hole of the outer gear through a second cylindrical roller bearing. In the axial direction of the crankshaft, a first ring member and a second ring member are arranged further outwards than the first cylindrical roller bearings. The first ring member is fixed to the crankshaft. The outer diameter of the first ring member is smaller than the outer diameter of the first cylindrical roller bearings. The second ring member is fixed to the support member. The inner diameter of the second ring member is smaller than the outer diameter of the first cylindrical roller bearings.
