A cam phaser for an internal combustion engine having such a gear mechanism is also provided. | 03-26-2015 |
20150133256 | LANTERN-TYPE GEAR UNIT - 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. | 05-14-2015 |
20150176443 | CHAIN-BASED TRANSFER DEVICE - A transfer device is provided with variable rotation angle having an internally toothed ring gear, an externally toothed sun gear, a transmitter element and an adjustable actuation device, wherein the transmitter element comprises a circumferential engagement device arranged between the ring gear and sun gear. The actuation device comprises an activation element that can be moved along the engagement device for rotation angle adjustment. In this case, the circumferential engagement device is partially engaged with the internal toothing of the ring gear and partially engaged with the external toothing of the sun gear by means of the activation element. Moreover, a correspondingly designed camphaser of a combustion engine, and a method for adjusting the relative rotation angle position of the camshaft to the crankshaft in a combustion engine, are provided. | 06-25-2015 |
20150176681 | LANTERN-TYPE PLANETARY GEARING - An epicyclic gearing, particularly a planetary gearing, has at least two central wheels and at least one planet wheel, whereby the at least one planet wheel engages simultaneously with two central wheels in order to transmit a movement of the one central wheel to the other central wheel. The at least two central wheels are thereby formed as lantern elements and the at least one planet wheel is formed as a lantern wheel. Alternatively, the at least one planet wheel is formed as a lantern element and the at least two central wheels are formed as lantern wheels. | 06-25-2015 |
