  • Patent number: 11073194
    Abstract: A planetary gearset (6) has a sun gear (10) connected rotationally fixedly to an input shaft (8), a carrier (15) that carries planetary gears (11) and is connected rotationally fixedly to an output shaft (16), and a ring gear (14) fixedly connected to a housing (4) that encloses the planetary gearset (6). To reduce the noise emission from the planetary gearset with as little structural complexity as possible without reducing its efficiency due to pressure rings that are guided and slide against the planetary gears and the carrier, the sun gear (10), the planetary gears (11) and the ring gear (14) are provided with helical teeth and the input shaft (8) is at least indirectly supported on the housing (4), in both axial directions, by way of a single roller bearing (20).

  • Patent number: 9478345
    Abstract: A converter unit includes: a housing with a moulded-on hollow cylinder that extends into the housing; a non-magnetic toroidal core supporting a first secondary winding, contacting the housing bottom concentrically with the hollow cylinder and is embedded in a solid compound; a magnetic toroidal core supporting a second secondary winding, arranged concentrically with the hollow cylinder above the non-magnetic toroidal coil; and a casting compound with which the housing opening is closed. To achieve a compact converter unit, a first planar spacing element is arranged between the first and the second secondary windings, directly contacting the first secondary winding and the second secondary winding. In addition, electrically insulating particles fill out the space between the second secondary winding and the housing wall, and the casting compound extends at least up to the particles, which lie at the top towards the housing opening.
