Reducing gear and starter device of an internal combustion engine

摘要

The invention relates to a reducing gear (3), in particular for a starter device (1) of an internal combustion engine, for speed-reducing coupling of a drive shaft and a driven shaft (5, 7), said coupling accomplished by way of at least two toothed gears (11) that engage with one another. The toothed gears (11) comprise straight cogs, and the cogging (30) is extra deep cogging (31). The invention further relates to a starter device (1) of an internal combustion engine.

主权项

1. A reducing gear (3) for speed-reducing coupling of a drive shaft and a driven shaft (5, 7), by means of at least two gearwheels (11) which engage with one another, characterized in that the gearwheels (11) have straight-cut toothing and the toothing (30) is extra deep toothing (31), wherein the reducing gear (3) is a planetary gear mechanism (4), with a sun gear (8), a ring gear (9) and at least one planet gear (10), which is arranged between the sun gear (8) and the ring gear (9) and engages therewith, and wherein the extra deep toothing (31) has an effective minimum profile coverage of at least two between the sun gear (8) and the planet gear (10).
