Embodiment Construction

[0028] according to figure 1 The perspective partial exposure of FIG. 2 shows an embodiment of a lantern-type gear unit 1 according to the invention, in the embodiment shown here, the lantern-type gear unit 1 being used as a camshaft adjuster 2 of an internal combustion engine. For this purpose, a gear unit 1 is arranged on one end of the camshaft 3 and allows a rotational movement exerted via the gear unit 1 to be transmitted via the valve cam 4 to a control valve (not shown) of the internal combustion engine. It can be clearly seen from the exposed part of the gear unit 1 that the lantern-shaped gear unit 1 is configured as a two-stage gear unit, the first gear stage 5 is arranged on the side of the gear unit facing away from the camshaft 3, and the second gear stage 6 is arranged on the side facing away from the camshaft 3. Gear unit side of camshaft 3.

[0029] According to the configuration of this two-stage lantern-type gear unit 1 as an eccentric gear arrangement, the ...

Abstract

A lantern-type gear unit, in particular for a camshaft adjuster, comprising at least two meshing gear wheels, a first gear wheel being configured as a lantern gear wheel and a second gear wheel including a lantern gear ring that engages with the lantern gear wheel. The lantern gear ring comprises at least one first annular bolt holder and a plurality of bolts arranged on the boundary of the bolt holder. The annular bolt holder has, together with the bolts, a circumferential contour that is overlap-free with respect to the lantern gear wheel in an axially parallel direction, so that the annular bolt holder can, together with the bolts, be assembled with the lantern gear wheel in an axially parallel direction. A camshaft adjuster for an internal combustion engine comprising such a lantern-type gear unit is also provided.

Description

technical field [0001] The invention relates to a lantern-type gear unit comprising at least two meshing gears, a first gear configured as a toothed lantern gear, a second gear comprising a lantern ring gear engaging with the lantern gear, said lantern ring gear comprising at least one first ring A bolt holder and a plurality of bolts arranged on the border of the bolt holder. Furthermore, the invention relates to a corresponding camshaft adjuster for an internal combustion engine. Background technique [0002] Conventional gear units, whether they are configured as toothed gearing, planetary gearing or eccentric gearing, are used in the prior art as single-stage or multi-stage gearing for various applications. In addition to the actual toothed gearing, planetary gearing or eccentric gearing can also include toothed gears and in addition to the shaft which remains fixed relative to the frame (without changing its position in the gearbox) A rotary shaft that rotates eccentr...
