82 FACE SPLINE MOLDING DEVICE AND FACE SPLINE MOLDING METHOD EP12800950.3 2012-05-23 EP2722115B1 2018-03-07 KIMURA, Takahiro; MATSUNAGA, Hiroshi
Provided are a face spline forming apparatus and a face spline forming method, with which fluctuation of an inner diameter of a cup section can be suppressed and a face spline can be formed stably. An outer joint member formed by the face spline forming apparatus and the face spline forming method, and a constant velocity universal joint using the outer joint member thus formed are proposed. The face spline forming apparatus comprises: a punch member (50) having a tooth portion (62) for forming a face spline (28); a pedestal (53) having an end-surface receiving surface (52) for receiving an opening end surface (51) of a cup section (7); and a shaft member (57) having an inner-surface receiving surface (56) for receiving a bottom-wall inner surface (55) of the cup section (7). The opening end surface (51) and the bottom-wall inner surface (52) are brought into a simultaneous pressure receiving state. In this state, the punch member performs rocking motion to form the face spline (28) in a bottom-wall back surface (26a) due to plastic deformation caused by the tooth portion (62) of the punch member (50).

90 Process for fabrication of rack shaft and fabrication machine therefor EP98103303.8 1998-02-25 EP0860225A3 1999-03-17 Yagi, Tadashi

A steel pipe having a circular sectional form is retained by a retainer. A rotatable first roller is pressed against an intermediate portion of the steel pipe. In this state, a pusher causes the steel pipe to move axially of the steel pipe. This causes the steel pipe to be plastically deformed while maintaining the first roller in rolling contact with the steel pipe whereby a flat portion is formed at the intermediate portion of the steel pipe. Subsequently, a second roller for forming rack teeth which is formed with teeth at its outer periphery is pressed against the flat portion of the steel pipe while the steel pipe is relatively moved in the axial direction thereof. This causes the flat portion of the steel pipe to be plastically deformed for formation of rack teeth at the flat portion.

A method and apparatus for making rotary die racks (12) having an elongated shape including a partially circular forming face (16) of less than 180° and a flat mounting surface (26) that faces in the opposite direction as the forming face (16). Cast metal blanks of the die racks are secured to a rotatable spindle (10) in a side-by-side relationship to turn the forming faces (16). Forming projections, i.e. teeth that extend parallel to the axis of the forming face, are then cut in the turned face (16). Heat treating of the die racks (12) is then performed before mounting thereof on a fixture to perform a finish grinding of the teeth. The spindle preferably includes a spindle member and a central shaft on which the spindle member is mounted for rotation. The fixture includes a pair of spaced end plates and a bed that extends between the end plates and has a stop and an adjustable positionerforclamping the die racks.

95 Device for manufacturing rack shaft JP33705394 1994-12-27 JPH08174126A 1996-07-09 YASUDA TSUTOMU; MINAMOTO ATSUSHI
PURPOSE: To form rack teeth on a side face of a base stock by comparably small force and to obtain a rack shaft whose burrs are reduced by sliding the hollow base stock for rack shafts and a form-rolling roll each other. CONSTITUTION: By relatively sliding the base stock 11 for rack shafts and the form-rolling roll 27 by a sliding means 24 in the tangent direction of the form-rolling roll 27, the rack teeth 12 are formed by rolling on the base stock 11 for rack shafts. At this time, the form-rolling roll 27 is in press-contact with the base stock 11 for rack shafts, but the base stock for rack shafts is relatively slid on the form-rolling roll 27 in the tangent direction, so the rack teeth 12 are formed by rolling on the base stock 11 for rack shafts. The center distance between the form-rolling roll 27 and the base stock 11 for rack shafts is narrowed by a feeding means 25 every prescribed stroke of the relative slide to the base stock 11 for rack shafts. In this way, since the form-rolling roll 27 is caused to bite the base stock little by little every prescribed stroke of the relative slide, large force is unnecessary at one time and the rack teeth 12 are formed by comparably small force.

97 Manufacture of timing gear for variable speed JP27371088 1988-10-28 JPH02121740A 1990-05-09 TOMITA MIKIO; FURUYA HIROYUKI
PURPOSE:To prolong the life of a rolling die and to prevent burrs from falling when the die is used by forming recessed stripe grooves on the deddendum in the lengthwise direction when the stock of timing spline teeth is forged and press-forming a reverse tapered gear surface with rolling dies. CONSTITUTION:The spline gear 11' for the timing gear is made. Recessed stripe grooves 12 are formed on this addendum. When the tooth surfaces 13' is roll- formed to a reverse tapered tooth surfaces 13, the excess thickness flows from the formed part of the tooth surfaces toward the deddendum but the excess thicknesses flow to bury the recessed stripe grooves 12 formed on the deddendums does not make burred projections. Consequently, the load to the rolling die is reduced and the life is elongated. Besides, the excess thickness does not fall-off, and a change gear is not broken by the excess thickness like fallen burrs after the gear is assembled to a gear box.
98 Manufacture of grooved metal bar JP28357786 1986-11-27 JPS63137535A 1988-06-09 FUKUDA HIROSHI; AZUMA HIDEKI
PURPOSE:To obtain at low cost a grooved metal bar of high accuracy without any strain by forming the range performing a grooving in a thin part and rolling the thin part by using a roll having a projecting bar thereafter. CONSTITUTION:A thinner part 1B is formed by rolling or cutting the range performing a grooving in the longitudinal direction of a metal bar 1 and an annealing and buffing are executed on the metal bar 1 provided with the thinner part 1B thereafter. In succession a rolling is performed once or several times by arranging between the roll 2 with projecting bar having plural projection bars in a rolling stage and a flat roll 3 the thinner part 1B of said metal bar 1 so as to conform to the projection bar part 2A of the roll 2 with projecting bar. At this rolling time the groove lower part 1C performing a grooving by the projection bar of the roll 2 with projecting bar is extruded by the projecting bar, coming into the recessed part between the projecting bar of the roll 2 with projecting bar 2 and the projecting bar. A straightening by a leveler is thereafter performed as the final stage.
