The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

Disclosed is a counter-roller active power flexible spinning device for a large cylinder, including a rack unit, a spindle unit, an outer roller unit, and an inner roller unit. A spindle turntable of the spindle unit is used to fix a cylinder blank. A second driver drives the spindle turntable to rotate, thereby achieving the rotation of a cylinder blank. A first driver drives the spindle turntable to be axially fed along a cylinder through a spindle platform. A third driver of the outer roller unit can drive an outer roller to rotate, and a fourth driver drives an outer roller seat to be radially fed along the cylinder at the top of an outer pillar. A fifth driver of the inner roller unit can drive an inner roller to rotate, and a sixth driver drives an inner roller seat to be radially fed along an inner roller disk.

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.
