摘要： A method of producing a sintered body (1) having different cross-sections along a main axis (5), in particular a toothed-belt or chain wheel, by compression moulding a sintering powder in the direction of the main axis (5) and subsequent sintering. At least two partial bodies (6, 7), which can be form-fitted into each other in the direction of the main axis (5), are pressed from sintering powder, which partial bodies each form an axial portion of the sintered body (1) with different cross-sections, and that the separately pressed and possibly presintered partial bodies (6, 7) are jointly sintered after joining them together.

摘要： A process for powder metallurgic manufacture of a coupling body (1) with a crown (2) of coupling teeth (3) is described, whose flanks (5) going out from wedge-shaped end faces (4) are in relief, such that a formed body with coupling teeth (3), which have wedge-shaped end faces (4), but flanks (5) parallel to axis, is pressed out of a sintering powder and sintered to a molded blank, whose coupling teeth (3) for forming the flank reliefs are subjected to axial compression molding between two form tools (9, 10) on the one hand for the wedge-shaped end faces (4) and on the other hand for the flank reliefs. To create advantageous processing conditions it is suggested that during compression molding of the flank reliefs in the transition region between the flanks (5) and the wedge-shaped end faces (4) a flank-side interlocking shoulder (7), with a rounded transition (8) to the wedge-shaped end faces (4) and lying in the mold surface (11) of the form tools (9, 10), is pressed into the flanks (5) of the coupling teeth (3).
摘要翻译：描述了一种用于具有联接齿（3）的冠部（2）的联接体（1）的粉末冶金制造方法，其楔形端面（5）从楔形端面（4）外侧脱离，使得具有楔形端面（4）但平行于轴线的侧面（5）的具有联接齿（3）的成形体从烧结粉末中压出并烧结成模制坯料，其成形齿（3）为了形成楔形端面（4），另一方面用于侧面浮雕，用于形成侧面浮雕的两个成形工具（9,10）之间经受轴向压缩模制。为了产生有利的加工条件，建议在侧翼（5）和楔形端面（4）之间的过渡区域中的侧面浮雕的压缩模制期间，具有圆形过渡的侧面互锁肩部（7）（8）到所述楔形端面（4）并且位于所述成形工具（9,10）的模具表面（11）中，被压入所述联接齿（3）的侧面（5）中。
