摘要： The object of the invention is to provide a rack shaft having two rack teeth groups (A2,B2) and hollowed throughout the whole body, to lightweightize the shaft and to reduce the cost. The two rack teeth groups (A2,B2) are located longitudinally apart from each other and have phase difference related to an angle around the axis of the shaft. After the two rack teeth groups (A2,B2) are formed simultaneously or sequentially by die forming on the flat bottoms of the workpiece beforehand gutter-shaped, the legs of the gutter-shaped workpiece are bent to butt to each other and, thereby, a tubular body of the shaft is given to the workpiece. The centers of the material are offset beforehand corresponding to the phase difference.

摘要： A manufacturing method of a hollow rack bar wherein the load imposed on the rack teeth configuration of a forming die is reduced and precision level of the formation of rack teeth is improved. After the formation of a flat portion (12), a steel pipe (10) is placed in the forming die (14) having a rack teeth configuration (14a) and a plurality of mandrels (16) having extruding portions (18,19) of different sizes are sequentially inserted into the steel pipe (10) in order to form rack teeth (1a). A mandrel (16) having a planar extruding portion (22) is firstly inserted and then a mandrel (16) having an extruding portion with an approximately central depression (26) in the longitudinal direction is inserted. The width of the mandrels (16) is smaller than the inside diameter of the steel pipe (10).

摘要： 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.
摘要翻译：具有圆形截面形状的钢管由保持器保持。可旋转的第一辊被压靠在钢管的中间部分上。在该状态下，推杆使钢管沿钢管轴向移动。这导致钢管塑性变形，同时保持第一辊与钢管滚动接触，从而在钢管的中间部分形成平坦部分。随后，在钢管相对于其轴向相对移动的同时，用于形成在其外周形成有齿的齿条齿的第二辊被压在钢管的平坦部分上。这导致钢管的平坦部分塑性变形以在平坦部分形成齿条齿。

摘要： The invention relates to a method for producing a steering gear rack (100), which has a tooth-set segment (110) having a steering tooth set (115) and a screw segment (120) having a recirculating ball screw (125), comprising: - providing a rod-like blank composed of a solid metal material; - hollowing out the screw segment (120) by means of deep-hole drilling at one end, wherein a deep blind hole (130) extending axially through the screw segment (120) is produced; and - producing the recirculating ball screw (125) on the hollow screw segment (120) by means of machining. The invention further relates to a steering gear rack (100) for a motor vehicle produced by means of said method, said steering gear rack comprising a tooth-set segment (110) having a steering tooth set (115) and a screw segment (120) having a recirculating ball screw (125), wherein, despite the one-piece production, the tooth-set segment (110) is solid and the screw segment (120) is hollow.
