摘要： Apparatus and associated methods relate to a unitary ring gear-flange body (URGFB). In an illustrative example, the flange body may be spin-formed and may, for example, include a riser body extending substantially parallel to a longitudinal axis and a flange extending substantially radially outward from the riser body. To the riser body may, for example, be welded a ring gear to form a unitary assembly, the ring gear having an axis of revolution aligned with the longitudinal axis. A continuous coating may, for example, be applied to at least a selected portion of a surface of the unitary assembly. Various embodiments may advantageously provide a cost-efficient, weight-efficient, and/or time-efficient unitary body which may, for example, be coupled to machinery to provide a shaftless torque-transmitter.

摘要： A method for manufacturing a gear toothing on a metallic workpiece and a tool device for calibration of a gear toothing inlet and/or a gear toothing outlet of a gear of the metallic workpiece. The method includes producing the gear toothing by forming manufacturing and performing a compression process to calibrate a gear toothing inlet and/or a gear toothing outlet of the gear toothing, wherein a gear tooth shape and a gear tooth length are adjusted during the compression process. The tool device includes a workpiece location for accommodating the workpiece, an axially movable die selectively engageable with the gear toothing, the die supporting the gear toothing and predefining the gear tooth shape to be adjusted on the gear toothing inlet and/or on the gear toothing outlet, and at least one axially movable compression ring which calibrates the gear toothing inlet and/or gear toothing outlet by a compression process.

摘要： A workpiece executes a rotation movement about a longitudinal axis and is machined by a tool in a multitude of reshaping engagements, in which an active region of the tool comes into contact with the machining region. The tool is held by a tool holder. The tool holder is mounted in an orbiting body so as to be rotatable about a rotation axis and is driven to carry out a rotating movement about the rotation axis, and is driven to carry out an orbiting movement by the orbiting body. Rotation movement of the workpiece is synchronised with the orbiting movement of the tool holder and the rotating movement of the first tool holder is synchronised with the orbiting movement of the tool holder.

摘要： A method of manufacturing a tooth-shaped component including a process of draw-forming a workpiece so as to obtain a cylindrical container, which has a bottom surface portion and a side surface portion; a diameter-reducing process of reducing the diameter of a particular part in which a tooth tip portion is to be formed in the side surface portion of the cylindrical container, so as to increase the thickness of a corner portion such that an external shape of the corner portion between the bottom surface portion and the side surface portion satisfies the following conditional expression (ΔR+ΔH)≤2t; and a tooth shape-forming process of forming the tooth tip portion in the particular part of the cylindrical container reduced in diameter in the diameter-reducing process, so as to obtain a tooth-shaped component which has the bottom surface portion, the side surface portion, and the tooth tip portion.

摘要： A method for forming a component utilizing ultra-high strength steel and components formed by the method. The method includes the step of providing a flat blank of ultra-high strength 22MnB5 steel. The next step of the method is cold forming the flat blank into an unfinished shape of a component while the blank is in an unhardened state. Then, heating the unfinished shape of the component and generating a spline form thereon. The method proceeds by forming a finished shape of the component using a quenching die resulting in a fine-grained martensitic component material structure and enabling net shape processing to establish final geometric dimensions of the component.

摘要： A method for roll-forming disk carriers or the like, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in their interior, which roll out the disk carrier to be formed with their outer circumference and thus impart toothing on the disk carrier to be formed, wherein the forming depth of the profile rollers at the disk carrier to be formed is designed in such a way that a narrow, peripheral, self-contained, unformed bridge remains between the inner diameter and the outer diameter of the toothing, wherein the bridge increases the engine-speed strength of the disk carrier as a hoop band cylinder that is integrated into the toothing.

摘要： A planetary drive includes a planet carrier and planetary gears. The carrier includes two axially-facing carrier plates and at least one connecting element. The connecting element is a linear strip of metal that is bent to take the shape of a cylinder for assembly. The strip of metal connects the two carrier plates while maintaining them in a spaced apart relationship. The strip includes a plurality of openings or holes for receiving a part of the planetary gears as they rotate. The strip is a separate element from the carrier plates, but is assembled to and between the plates.

摘要： For machining a concave-convex gear in which concave teeth of the concave-convex gear and convex teeth of a mating gear are formed in a circumferential direction, to allow torque transmission to or from the mating gear, in a trajectory extracting step a relative movement trajectory of each convex tooth of the mating gear with respect to the concave-convex gear at the time when torque is transmitted is first extracted as a machining target. Then, in a machining step, the concave teeth of the concave-convex gear are machined on a disc-shaped workpiece by moving at least one of the disc-shaped workpiece and a working tool such that a relative movement trajectory of the working tool with respect to the disc-shaped workpiece coincides with the relative movement trajectory of each convex tooth of the mating gear with respect to the concave-convex gear extracted in the trajectory extracting step.
