摘要： An intermittent transmission apparatus according to this invention, broadly, includes a driving element and a driven element. The driving element comprises a first cam having a first cam surface, a second cam having a second cam surface, and an intermediate member displaced between the first and second cams. The driven element comprises a driven element main body having recesses for contacting a plurality of rollers arranged on the intermediate member, bearings erected on the driven element main body to be pushed by the first cam surface, and bearings erected under the driven element main body to be pushed by the second cam surface. During non-drive period of the driven element, the bearings contact a circular arc surface of the second cam, and further the recesses contact the plurality of rollers, to restrict rotation of the driven element.

摘要： Two cam-bearing holders of an indexing drive are bolted to opposed side walls of a housing in such a way that respective positions of the cam-bearing holders are adjustable in a plane orthogonal to an axial direction of the cam shaft along the side walls. Each of the cam-bearing holders has a first reference surface for positioning the cam-bearing holder relative to a positioning reference surface of the output shaft in the axial direction of an output shaft and a second reference surface for positioning the cam-bearing holder in a direction orthogonal to the axial direction of the output shaft. With such novel arrangements, there is achieved an improved cam-positioning mechanism for the indexing drive which can accurately adjust a meshing engagement between the cam and roller followers of the output shaft and thereby allows the indexing drive to be assembled with greatly increased accuracy.
