摘要： A method of making a commutator ring (2) for a commutator, which is provided with a plurality of commutator segments (7) with connection lugs (10) and anchoring means (44) and which is cold-formed by reduction and gauging in a single manufacturing step of a forming apparatus from a blank (1) with preformed segmental grooves (6) and a flange (4) which can subsequently be made into connection lugs. The forming apparatus is provided with a single or multi-stage, single or multi-part die. The blank is pressed against the die by radially disposed slides (39, 59) of the apparatus which are adjacent each commutator segment (7) and connection lug (10). Finally, during retraction of the die from the blank, the anchoring means (44) are formed on the commutator segments by a gauging apparatus being drawn through the tubular blank to "mushroom" inner teeth of the blank and shape them to form dovetail shaped anchors in a commutator hub sleeve. The die serves as an ejector for the finished commutator ring during its return movement to its initial position. After assembly to the commutator hub sleeve, the remaining connecting elements (8, 11) which held the commutator segments and connection lugs in closed, ring shape are removed or severed.

摘要： A method of forming flanged commutator segmental rings in a single power stroke by cold-extrusion which assures full formation of the inner ribs which become commutator segments, so that the segments will anchor well and resist centrifugal force at high rotational speed. The extrusion apparatus has an inner rib-forming die (18) and an outer ring-shaped flange-forming die (16). In the first stage of the power stroke, a ring-shaped blank (1) is formed into a flange precursor and a shaft portion (24) with inner ribs. In the second stage of the power stroke, the ring-shaped die (16) forms the flange (4) while the rib-forming die (18) forms a longer shaft (3) with a full complement of inner ribs (5) and a counter-punch (13) maintains pressure.

摘要： A commutator for electric machines has a multiplicity of segments (2), which are provided with anchoring means (5) for securing in the insulating body (13), are joined at one end with associated winding ends (8) of a rotor, and are divided from one another in the circumferential direction by slots (10) which are filled with insulating material (15). The insulating material forming the insulating body (13) and filling the slots (10) as insulating lamellas (15) protrudes radially, in the form of widened supports (16), beyond the insulating lamellas (15). The supports (16) form the boundary in the circumferential direction for the terminal grooves (17) of the segments (2) for the rotor winding ends (8), which are welded to the segments (2).

摘要： To retain end portions (10,11) of armature conductors in slots (6, 37) formed in radially projecting lugs (5) of armature segments (2) of a commutator (1), the side walls of the slots are formed with a deviation from a plane surface, for example by a recess (7) or an inwardly extending projection (38), and the end portions (10, 11) of the windings are then placed in the slot and deformed under punch or stamping pressure to form, together with the recess or the region adjacent the projection, an interfitting projection-and-recess connection which will withstand high centrifugal forces, and prevent loosening of the connection under conditions of shock, vibration, high temperatures and temperature changes, to make the connection particularly suitable for installation in mobile, typically automotive dynamo electric machines. The apparatus to make the connection includes a punch press which can either sequentially or simultaneously place one or two end portions (10, 11) of conductors into the slots (6, 37) of the lugs. For further clamping, the edges of the lugs adjacent the walls of the slots can be deformed, for example by shearing, to overlap the uppermost end portion (11) of the conductors.
摘要翻译：为了将电枢导体的端部（10,11）保持在形成在换向器（1）的电枢段（2）的径向突出的凸耳（5）中的槽（6,37）中，槽的侧壁形成有例如通过凹部（7）或向内延伸的突起（38）与平面的偏离，然后将绕组的端部（10,11）放置在槽中并在冲压或冲压压力下变形以形成与凹部或邻近突起的区域一起，形成能够承受高离心力的相互配合的突出和凹陷连接，并且在冲击，振动，高温和温度变化的条件下防止连接的松动，从而使连接特别适合安装在移动电话，通常是汽车发电机。用于制造连接的装置包括冲压机，其可以顺序地或同时地将导体的一个或两个端部（10,11）放置到凸耳的槽（6,37）中。为了进一步夹紧，邻近狭缝壁的凸耳的边缘可以例如通过剪切而变形，以与导体的最上端部分（11）重叠。
