A gear has a gear body made of a first plastic material. The gear body has an axis of rotation, external toothing arranged around an axis of rotation, a centrally located receiving opening, and an intermediate portion located between the external toothing and the wall of the receiving opening. The gear body is fixedly integrally formed on a support body, which is arranged at least partially in the intermediate portion and is made of a second plastic material having a higher stiffness and lower elasticity than the first plastic material, such that surface portions of the external toothing, of the wall of the receiving opening, of the intermediate portion, and of the support body form a substantially flat end face of the gear. The external toothing is helical toothing with teeth which, at least in portions, extend at a helix angle to the axis of rotation.

Gear

A toothed gear for use in a gearing, comprising a base body that forms a ring gear with a number of first teeth having a first deformability and a number of second teeth having a second deformability, wherein the second deformability is greater than the first deformability and to a gear pair of a gearing, comprising such a toothed gear and at least one further toothed gear which can be made to mesh or is in mesh with the toothed gear. The invention relates moreover to a gearing with such a gear pair.

Gear for use in a gear transmission, gear pairing of a gear transmission and gear transmission with such a gear pair

The present invention relates to a gear wheel comprising an outer part () having a gear rim (), an insert () which has an insert outer diameter (dEa) and a receptacle section () having an insert part inner diameter (dEi) for forming a shaft-hub connection, and a connecting part () which is arranged between the insert part () and the outer part () and which connects the insert part () and the outer part () in a formfitting and/or materially-bonded and/or friction-locked manner, wherein the connecting part () has a number of ribs () or the connecting part () is formed by a number of ribs (), wherein the ribs () each extend along a tangent (T) which abuts a tangent circle (CT), wherein the tangent circle (CT) has a tangent circle diameter (dCT) which is larger than or equal to the insert inner diameter (dEi) and smaller than or equal to the insert outer diameter (dEa).

Gear wheel

A gearwheel pair for a gear unit, comprising a first gear and a second gear, which can be meshed with one another, wherein the first gear consists entirely or partially of metal or plastic and the second spur gear comprises an outer part having a gear rim made of a first plastic and having a number of injection-molded portions, an inlay part made of metal, and a connecting part, which is arranged between the inlay part and the outer part and is made of a second plastic for the interlocked and/or materially-bonded connection of the inlay part and the outer part and further relates to the second spur gear per se, a gear unit having such a gearwheel pair, and a method for producing a second gear, which is used for such a gear unit.

Gear, gearwheel pair, and method for producing a gear

The present invention relates to a gear ring carrier part () for a two- or multi-component gear (), the gear ring carrier part () having a circular ring section () rotating in the circumferential direction about an axis of rotation (A), a gear ring () arranged radially on the outside of the circular ring section (), and an extension () extending radially inward from the circular ring section (), the extension () having a first extension face () and a second extension face (), a number of first ribs () and an equal number of first pockets () being arranged on the first extension face (), and/or a number of second ribs () and an equal number of second pockets () being arranged on the second extension face (), the first ribs () and the first pockets () and/or the second ribs () and the second pockets () each extending radially and being arranged adjacent to one another in the circumferential direction. The invention also relates to a two-component or multi-component gear () with such a gear ring carrier part ().

The present invention relates to a multi-component gear () with an axis of rotation (X) and a first end face () and a second end face (), having an inner part () and an outer part () made of a plastic with at least one injection-molding section (), wherein the outer part () is arranged on an outer lateral surface () of the inner part () in a form-fitting and/or integral manner on the inner part (), and wherein the outer part () on the first and/or the second end face () has at least one tab () which is free-standing in the circumferential direction around the axis of rotation (X) and which protrudes over the relevant end face () of the inner part (). The present invention also relates to a gear () and a planetary gearset ().
