The present application relates to a wheel rolling device, which is composed of a lower lifting rotating system, first rolling systems, a synchronous clamping drive system, a second rolling system and a third rolling system. The present application may not only strengthen the center hole, the inner and outer rims, the upper and lower rims, the flange root and the like portion of the wheel by rolling, but also may strengthen the bolt holes and valve holes of the wheel by extrusion; at the same time, the present application has the characteristics of high automation, powerful function, advanced technology, strong versatility and safe and stable performance.

Provided are an oil receiver (20) having an annular recess portion (52) which faces an entire circumference of an outer circumferential edge of a concave spherical portion (36), and a guide member (21) which guides lubricating oil, which has flowed out from a spherical engagement portion between a convex spherical portion (24) and a concave spherical portion (36), toward an annular recess portion (52).

The tooth part includes: a tubular portion having an inner tooth portion formed on an inner peripheral surface and an outer tooth portion formed on an outer peripheral surface; a plurality of inner peripheral wall portions that each extend in an axial direction of the tubular portion and form a tooth tip portion of the inner tooth portion and a tooth bottom portion of the outer tooth portion; a plurality of outer peripheral wall portions that each extend in the axial direction and form a tooth bottom portion of the inner tooth portion and a tooth tip portion of the outer tooth portion; and an annular rib that is joined to the outer peripheral wall portions and that extends in an annular shape on an open end side with respect to the inner peripheral wall portions in the axial direction and radially outward from the inner peripheral wall portions, at an open end of the tubular portion.

Provided are an oil pan (20) which has an annular recess portion (52) facing an outer circumferential edge of a spherical concave portion (36) throughout a whole circumference; and a cover (21) which is constituted in a tubular shape, of which one axial end portion is rotatably supported by a part adjacent to a radially inner side of the annular recess portion (52), and of which an axially opposite end portion is rotatably supported by a part of a shaft-equipped spherical seat (18) on the one axial end side.

A sweep auger system having a driveshaft with auger flighting and a backboard extending a length from an inward end to an outward end. An input of a gearbox is connected to an outward end of the drive shaft and a sweep wheel having a plurality of notches, arms and feet is connected to an output of the gearbox. A drive shield is placed around a rearward side of the sweep wheel that forms a channel that is configured to capture grain agitated by the sweep wheel. A guide plate is connected to the gearbox and covers a portion of the gearbox. The guide plate angles from an upper outward edge downward and forward to a lower inward edge that is configured to urge the grain captured within the channel of the drive shield to move in front of the sweep auger system reducing grain left in the grain bin.

The present application discloses wheel engraving equipment, which includes a lower lifting system, lower flange engraving systems, inner rim engraving systems, a wheel positioning and clamping system, an upper lifting and rotating system, a synchronous clamping and rotating system and the like.

A spinning forming method includes: preparing a plate including a back surface at which a ring-shaped projection is formed along an outer peripheral edge of the plate, a ratio of a thickness at a reference position of the plate to a thickness at a tip end of the projection being 0.7 or less, the reference position being a position where an inclination of a portion of the back surface which portion extends toward the tip end of the projection is 45 or more; rotating the plate; moving a processing tool outward in a radial direction from an inner side of the projection to a position above the projection while pressing the processing tool against a front surface of the plate that is rotating; and locally heating a portion of the plate against which portion the processing tool is pressed.

A method for manufacturing a wheel hub (300) for a non-pneumatic wheel (100). A sheet (332) of material may be folded, cut, bent, and otherwise processed to form portions of the desired wheel hub(300). The wheel hub (300) may be connected with an annular band (108) through load supporting members (106) that can be selectively connected and disconnected from the hub (300).

A new method of building a vehicle wheel utilizing hydro forming from a solid piece of steel metal sheet.
