摘要： In order to provide a wormwheel gear (1) which is mouldable the toothing (2) which is disposed at least about a portion of the periphery of the gear has a decreasing pitch diameter over a first axial portion (6) thereof extending from one transverse face (3) of the gear and is straight and has a non-increasing, and preferably constant, pitch diameter over a second axial portion (7) extending to the other transverse face (4) of the gear. Such a configuration enables a moulding, which may be the gear or a green compact therefor, to be removed from the mould by simple relative axial movement of the moulding and mould, without the need to relatively rotate the mould or moulding.

摘要： A multiply-acting powder metal press is disclosed for making green form double helical gear compacts. The press has inner and outer lower punches, and an upper, outer punch. The upper and lower outer punches have left hand and right hand external helical profiles as chosen to produce a desired helical gear. The punches co-operate with left hand and right hand helical dies carried by the press about the punches. The helical faces require that the dies rotate relative to the punches during operation. A cam and roller mechanism may drive this rotation. The compact forming process commences with an open position in which powder is introduced to a vacant lower die cavity. The upper portions of the press advance downward to close the cavity. All parts of the press except the lower inner, or transfer, punch then move downward at the same speed to transfer powder to the extremities of the cavity. When transfer is complete both lower punches may be stopped, while the upper punches continue to advance. The dies advance at half the speed of the upper punches, rotating partially as they do so. Once the powder reaches its compacted density the upper and lower punches cease motion, but their dies continue to turn, separating themselves and compressed part. Finally, the part is ejected and the press returns to the initial condition.
摘要翻译：公开了一种用于制造绿色双斜齿轮压块的多功能粉末金属压力机。压机具有内外冲头和上冲头，外冲头。上下外冲头具有选择的左手和右手外螺旋轮廓以产生期望的斜齿轮。冲头与冲压机携带的左手和右手螺旋模具围绕冲头配合。螺旋面需要在运行期间模具相对于冲头旋转。凸轮和滚子机构可以驱动该旋转。紧凑的成型过程开始于将粉末引入空的下模腔的打开位置。压机的上部向下推动以关闭空腔。除了较低的内部或转移冲头之外，压力机的所有部件以相同的速度向下移动以将粉末转移到腔的四肢。当传送完成时，可以停止下冲头，而上冲头继续前进。模具以上冲头的一半速度前进，部分旋转。一旦粉末达到其压实密度，上下冲头停止运动，但它们的模具继续转动，分离自身和压缩部件。最后，零件被弹出，压机回到初始状态。

摘要： A device for producing compacts having main cylindrical elements and helically-shaped secondary elements from a powdery material, in particular a metal powder, has a female mould (1), at least one upper punch (2) mounted to rotate around its longitudinal axis and at least one bottom ram (3) mounted to rotate around its longitudinal axis. The upper punch (2) and the bottom ram (3) are motor-driven in the axial direction in relation to the female mould (2) and the upper punch (2) is rotated around its longitudinal axis besides being axially driven in order to describe a helical movement. The invention is characterised in that an electronic control (8) is provided, in that the bottom ram (3) is also motor-driven and in that the motors that rotate the upper punch and bottom ram (2, 3) are mechanically uncoupled from the motors that axially drive them and may be separately regulated by the control (8).

摘要： A multi-chain sprocket is manufactured by moulding a central hub (10) from a powder of a metal or metal alloy, and moulding a plurality of sprocket rings (11) from a powder of the same or a different metal or metal alloy. The moulded sprocket rings (11) are mounted on the hub (10) in required locations, then the rings are bonded to the hub (preferably by sintering). The product multi-chain sprocket is usually hardened or steam treated before the bore of the hub and the location face of the sprocket are finish ground.
