A gear unit includes a housing having a lower part and a cover part, e.g., fitted onto the lower part, and an output shaft and a driving shaft. The lower part includes a first support, a second support, a base plate, and side walls. Each side wall is connected, e.g., welded, the first and second supports. The first support is a closed annular structure, e.g., a closed ring. The second support is an open annular structure, e.g., an open ring. A first bearing, e.g., a double bearing, for rotatably supporting the output shaft is received in the base plate. A second bearing for rotatably supporting the output shaft is received in the bearing receiving part. The base plate is connected, e.g., welded, to the second support and to the bearing receiving part.

Gear unit including a housing having a lower part and a cover part

A gear unit includes a shaft, rotatably mounted via a first bearing, a housing part, and a cover connected to the housing part. The shaft has a threaded region onto which a nut is screwed, and a spacing sleeve and a disk are arranged between the nut and an inner ring of the spacing sleeve. The greatest outer diameter of the disk is greater than the greatest outer diameter of the spacing sleeve; the greatest radial distance of the disk relative to the rotational axis of the shaft is greater than the greatest radial distance of the spacing sleeve relative to the rotational axis of the shaft; and/or the radial spacing region covered by the disk and relative to the rotational axis of the shaft contains the radial spacing region covered by the spacing sleeve.

Gear unit having a shaft, a first bearing, a housing part, and a cover

A gear unit includes a shaft and a housing part. A bearing is received in the housing part, and a flange part is connected to the housing part. The flange part is sealed from the shaft using a first and a second labyrinth seal, and the first labyrinth seal is axially spaced apart from the second labyrinth seal. The shaft has an elevation that is arranged axially, e.g., in the axial direction, between the first labyrinth seal and the second labyrinth seal.

Gear unit having a shaft and a housing part

A drive device includes a gear unit, which is able to be driven by a motor and includes a pressure-lubrication system. The pressure-lubrication system has a distributor block, having a continuous longitudinal bore and continuous transverse bores. The distributor block is arranged as a single piece, in particular from metal such as steel or aluminum.

Drive device

A gear unit includes a housing, a trough for guiding oil and reducing losses due to splashing surrounding a circumferential section of a toothing part, particularly a gear wheel, especially in the radial and axial direction, the trough including at least three parts, e.g., at least one bottom plate and two side walls, the bottom plate being screw-connected to the two side walls, the trough being fastened to the housing, the trough having an opening, particularly a channel, especially at its lowest surface area, e.g., particularly at the surface area having the greatest radial distance, in particular, during rotational movement of the gear wheel, oil being conveyed from the oil pan of the gear unit through the opening between the trough and gear wheel, especially to a position higher than the level of the oil pan, the bottom plate and the side walls being stamped bent parts.

Gear unit having a housing

A gear unit includes a housing, a trough for guiding oil and reducing losses due to splashing surrounding a circumferential section of a toothing part, the trough including at least three parts, e.g., at least one bottom plate and two side walls, the bottom plate being screw-connected to the two side walls, the trough being fastened to the housing, the trough having an opening, the bottom plate and the side walls being stamped bent parts.

A gear includes helical toothing and is composed of segments, and each segment has a toothing section that has a helical toothing. Each toothing section of each segment is connected via first and second webs as well as connecting sections to the connection region, the connecting sections, and the first and the second webs are set apart from each other or are at least sectionally set apart from each other, e.g., such that the segment has a plurality of axially uninterrupted recesses, in particular three or more. The axial region covered by the first webs is set apart from the axial region covered by the second webs, in particular so that the segment has at least one recess that is uninterrupted in the circumferential direction.

Gear with helical toothing, and segment for a gear

A gear unit includes a housing, a trough for guiding oil and reducing losses due to splashing surrounding a circumferential section of a toothing part, particularly a gear wheel, especially in the radial and axial direction. The trough includes at least three parts, e.g., at least one bottom plate and two side walls, the bottom plate being screw-connected to the two side walls. The trough is fastened to the housing and includes an opening, particularly a channel, especially at its lowest surface area, e.g., particularly at the surface area having the greatest radial distance. In particular, during rotational movement of the gear wheel, oil is conveyed from the oil pan of the gear unit through the opening between the trough and gear wheel, especially to a position higher than the level of the oil pan. The bottom plate and the side walls are stamped bent parts.

Gear unit having a housing with lubrication groove

A housing for a gear unit includes a housing top part mounted on a housing bottom part, a first bearing mounting for a first bearing of a shaft being formed by a first bearing carrier of the housing top part and a first bearing carrier of the housing bottom part, a second bearing mounting for a second bearing of a shaft being formed by a second bearing carrier of the housing top part and a second bearing carrier of the housing bottom part, a first end area of a first bearing carrier of the housing bottom part and a first end area of a second bearing carrier of the housing bottom part being joined by two end plates set apart from each other.

Housing for a gear unit

A gear wheel includes helical toothing, and a segment for a gear wheel which is made up of segments, each segment having a toothing section having helical toothing, the toothing section being joined to a retaining section.

Gear wheel having helical toothing and segment for a gear wheel

A housing for a gear unit and a gear unit having a housing, the housing having a housing top part and a housing bottom part, the housing top part having a frame-like support section on which wall sections are molded, the frame-like support section being formed in one piece, thus integrally, with the wall sections, particularly as a casting, especially as a steel casting.
