A drive includes a transmission driven by an electric motor. A drive shaft of the transmission has multiple eccentric regions with differing widths in the axial direction, in which the high points thereof are offset relative to one another in the circumferential direction. The respective eccentric region is radially surrounded by a respective cam disk region, e.g., of a housing part of the transmission. Respective rollers are accommodated in respective recesses of a cage and arranged with a radial degree of freedom. The cage is rotationally fixed to the output shaft of the transmission. The output shaft along with the cage is rotatably mounted both relative to the cam disk regions and relative to the drive shaft. During operation, the respective rollers are made to roll and/or slide on the respective cam disk region by the respective eccentric region. The eccentric regions are arranged behind one another in the axial direction such that the dynamic imbalance is minimized and/or eliminated.

Drive including a transmission driven by an electric motor

A transmission includes a first housing part, a second housing part connected to the first housing part, and bearings accommodated in the first housing part and supporting an input shaft in a rotatable manner. The input shaft projects through a recess that extends through the second housing part, and a cover part is connected to the first housing part. The cover part or a flange part inserted into the cover part accommodates a sealing system, which provides sealing with respect to the input shaft. The second housing part has an inlet for lubricating oil, which terminates in an axial bore being open with respect to the side of the first housing part facing the cover part, and in a second annular space. The opening of the axial bore facing the cover part is covered and/or sealed by the cover part, and rolling elements of two bearings at least also restricting and/or surrounding the second annular space together with the first housing part.

Transmission and method for producing different transmissions, in particular a range of transmissions

A system for the contactless sealing of a rotatably mounted shaft with respect to a housing, and a gear unit, oil being provided in the interior of the housing, in particular, the rotating shaft protruding from the interior into the outer area; a centrifugal disk, joined in rotatably fixed manner to the shaft, having at least partially radially extending bores that connect oil from a centrifugal chamber to a collection chamber surrounding the centrifugal disk.

System for the contactless sealing of a rotatably mounted shaft with respect to a housing, and gear unit

A gear unit, including an input shaft, a bearing for supporting the input shaft being provided in a housing part of the gear unit, wherein a fan impeller is provided on the input shaft, the housing part being beveled at least in the surface area adjacent to the fan impeller and/or a beveled cowl being mounted on the housing part.

Gear unit

A gear unit having at least one shaft supported by a bearing in the gear unit housing,

A gear unit at least partially filled with oil, wherein 

Gear unit at least partially filled with oil

A gear unit, an oil scraping device being provided on the front of a rotatably supported gear wheel, in particular on a plane area of the front of a gear wheel.

In a system for contactlessly sealing a rotably mounted shaft from a housing, and a gear unit, oil is provided in the interior of the housing, the rotating shaft in particular projecting from the interior to the outer area, wherein a centrifugal disk is provided, which is connected to the shaft in torsionally fixed manner and has at least partially radially extending bores, which connect oil from a centrifugal chamber to a catch basin surrounding the centrifugal disk.
