摘要： The gear housing may be a housing to enclose a gear assembly of a land mobile vehicle. The gear housing may have an upper housing portion and a lower housing portion. The lower housing portion may have a wall reference position below a lowest surface structure of a gear assembly wherein a wall of smooth, generally non-planar surfaces may be positioned below a gear assembly centerline with an interior surface at the wall reference position adjacent the lowest surface structure with sufficient separation to avoid contact between the gear housing and the gear assembly. The wall may have at least one concave curved segment to position the wall adjacent to a contour of outer surface structures of the gear assembly, but not contacting the gear assembly. An upper housing portion may be attached to the lower housing portion to enclose the gear assembly.

摘要： A method of forming a ring gear from a ring blank includes providing a mandrel having a central axis and an outer annular forming surface. The outer annular forming surface defines a plurality of forming elements having a forming element axis offset from the central axis of the mandrel. The ring blank has a ring axis and is placed over the mandrel generally aligning the central axis of the mandrel with the ring axis of the ring blank. A roll is provided having a roll axis that is generally parallel with the element axis. The roll is forced radially inwardly while circumscribing the central axis. The roll pivots around the roll axis deforming the ring blank radially inwardly forming teeth on an inner surface of the ring blank that coaxial with the element axis and offset from the mandrel axis.

摘要： The invention relates to a method for cold-form profiling cylindrical, thin-walled hollow parts (1), comprising profiles (4) which extend in an essentially parallel manner in relation to the longitudinal axis (A) of the hollow part (1). At least one profiling tool (5) engages in a strike-like hammering manner with the outside of the hollow part (1) in a radial manner in relation to the longitudinal axis (A) of the hollow part (1). The profiling tool (5) engages, respectively, in an essentially vertical and oscillating manner on the surface of the hollow part (1). Then, the profiling tool (5) is displaced in an axial manner in relation to the hollow part (1) at a constant radial adjusting depth until the desired profile length is obtained.

摘要： A method permits replacement of components of existing epicyclic gear mechanisms of a wind energy system without having to lift the gear mechanism down from the gondola. In accordance with the method, the housing is divided up alternately in its first parting plane and in its second parting plane and moved apart. The center section of the housing, which includes the internal geared wheel, always remains connected with an adjacent section and therefore does not have to be moved with a hoist. Access to the components to be replaced is always guaranteed by the special method of opening. An installation bolt is also provided that is particularly suitable for implementing the method.

摘要： The present invention discloses a differential housing and a method operable to form the differential housing. The method includes the step of disposing a member having an outer surface on a mandrel. The member in the exemplary embodiment of the invention is a ring that enhances the strength of the finished differential housing. The method also includes the step of cold-working a housing preform by flow-forming the inner surface of the housing preform into conformance with the mandrel and with the outer surface of the member after said disposing step. The member is disposed in situ as the housing preform is cold-worked to produce the finished differential housing.
