Infinite transmission gearing countershaft comprises two parallel bevel gear pairs and planet gear to afford simply performed infinite gear ratio adjustment.

摘要

The intermediate gearing shaft (13) is formed by two parallel encircling gears (15,16,18,19,20) and (24,25,27,28,29) of adjustable gear ratio. The drive shaft (2) mounts a planet gear (4) and at one end carries the co-rotating planet gear sun wheel (6). The shaft is rotatably joined to the planet carrier (7) through the infinitely adjustable gearing (1). The countershaft gear (5) is made up of a first bevel gear pair (19,20) and a second pair (24,25), with gears (20,24) respectively adjusting along the countershaft (21). Gears (20,24) of the first pair and gears (19,20) are integrally joined and in this way form the bevel gearing adjusting along the countershaft. The offtake shaft (13) meshes with the outside teeth (37) of the internally toothed ring gear (11) as meshing with the planet gear wheels (10).
