摘要： A novel method of manufacturing a toothed disc is taught wherein the teeth can be cold formed to a relatively high set of tolerances in a relatively time-efficient manner. A cold-formed disc blank with an annular thickened ring about its periphery is forced through a set of tooth forming rollers which engage the annular thickened ring. As the blank is forced through the set of rollers, the rollers cold forming tooth structures in the annular ring. In some circumstances, the tooth structure can be a final desired tooth profile and in other circumstances, the disc blank may be forced through two or more different sets of tooth forming rollers, each set of tooth forming rollers contributing to the forming of the final, desired tooth profile.

摘要： The invention relates to a heat exchanger tube with a tube axis, with a tube wall, with a tube outside and with a tube inside. Continuously running, axially parallel or helically circling inner ribs are formed out of the tube wall on the tube inside, each inner rib having two rib flanks and a rib tip. A continuously extending groove is formed in each case between adjacent inner ribs. The rib tip has at regular intervals recurring elevations which have an essentially frustopyramidal form. In the solution according to the invention, the rib flanks of the inner ribs are raised in the radial direction on the contour line which is defined by the transitional edge of a rib flank to the rib tip, in that protuberances advancing out of the rib flank are formed in this region. Furthermore, the invention relates to a method for producing a heat exchanger tube.

摘要： In a camshaft for an internal combustion engine having a cam disk support shaft, to which a plurality of cam disks and a drive wheel are attached, the outer radius of the cam disk support shaft varies continuously in those sections in which the cam disks are attached. The cam disks have bores whose inner radius varies continuously and the cam disk support shaft is alternately provided with elevations and depressions in those sections in which the cam disks are attached, the elevations and depressions forming a wedge-shaped curve profile about the circumference of the section of the cam disk support shaft The elevations continuously enlarge the outer radius of the cam disk support shaft, the bores of the cam disks being matched to the enlarged portion of the outer radius of the cam disk support shaft, so that by relative rotation of the cam support shaft and the cam disks and also the drive wheel the components are firmly joined and the camshaft is formed.

摘要： When working a linear guide rail having one or more raceway grooves 2 on the side surfaces thereof, using rotary dies each including on the circumferential portion thereof a projection-shaped working portion matched in shape to the raceway groove 2, the raceway grooves 2 are rolled onto a rail blank work W. Since the raceway grooves 2 can be rolled with high accuracy by a single working step, the working time of the raceway grooves as well as the working cost thereof can be reduced.

摘要： The present invention provides an internally-toothed member of reduced size and enhanced quality, durability and productivity in manufacture. This internally-toothed member has a first cylinder portion and a second cylinder portion which is larger in diameter than the first cylinder portion. First and second internal teeth are formed to protrude radially inwardly from inner peripheral surfaces of the first and second cylinder portions respectively. Because a meshing portion can be formed as second internal teeth protruding from an inner periphery of the second cylinder portion, the diameter of the internally-toothed member is relatively small. Because the area between the second internal teeth and a concave portion and the concave portion itself do not decrease in thickness during formation of the second internal teeth, it is possible to prevent cracking and to thereby enhance durability of the internally-toothed member. Further, because there is no sagging of the inner peripheral surface of the meshing portion, the quality of the internally-toothed member is further enhanced.

摘要翻译： 本发明提供一种减小尺寸并提高制造质量，耐久性和生产率的内齿构件。 该内齿构件具有直径比第一气缸部分大的第一气缸部分和第二气缸部分。 第一和第二内齿形成为分别从第一和第二圆筒部分的内周表面径向向内突出。 因为啮合部分可以形成为从第二圆筒部分的内周伸出的第二内齿，所以内齿构件的直径相对较小。 由于第二内齿与凹部之间的区域和凹部本身在第二内齿的形成期间的厚度没有减小，因此能够防止裂纹，从而提高内齿构件的耐久性。 此外，由于啮合部的内周面没有下垂，因此进一步提高了内齿部件的品质。

摘要： The method includes making a fluid communication channel (44), which has a selectively variable cross-sectional area profile, in the inner face of a gas spring cylinder (32) so as to permit fluid communication at different selective rates bypassing around or across the piston assembly (68) of the gas spring (52)as the piston assembly (68) moves within the cylinder (32). Preferably the cross-sectional area profile of the fluid communication channel (44) is initially substantially the same throughout the length of the channel(44) and is thereafter selectively changed in certain portions of the channel (44) so as to restrict and in some instances block gas or fluid flow through the fluid communication channel (44).

摘要： A method for producing press-rolled tubes (3) with a press mandrel (1) and one or more pressure rollers (2), with the tube (3) being arranged between the press mandrel (1) and the pressure rollers (2) and being plastically deformed by means of force loading of the pressure rollers (2). To produce tubes with end wall thickenings, in a first working operation, a first press mandrel (1a) with a tailstock-end shoulder (4) is used. The pressure rollers (2) begin their transforming work at the tailstock-end shoulder (4) and work in the direction of the machine spindle. The half-finished tube (3a) is taken from the first press mandrel (1a), and, in a second working operation, the half-finished tube (3a) is clamped at the end with the wall thickening (5) which has already produced into a lathe chuck (6) (tensioning spindle or similar) mounted in the press-rolling machine, and a second press mandrel (1b), fastened on the tailstock end and having an outer diameter (d.sub.2) which corresponds to the inner diameter of the wall thickening, is pushed into the half-finished tube (3a). Then the pressure rollers (2) form the second wall thickening from the tailstock-end in the direction of the machine-spindle end.

摘要： A method of manufacturing a tie rod bar for a steering linkage of a motor vehicle. Between both end portions of a steel pipe material, through a multistage cold forging, there are formed a spherical section, a neck section, a first shaft section, a second shaft section smaller in diameter than the first shaft section, a hexagonal section, and a third shaft section smaller in diameter than the second shaft section, to thereby constitute the tie rod bar. Secondly, the neck section is formed at a portion of the first shaft corresponding to a proximal end portion of the spherical section, a boot groove is formed at a given position on the second shaft section, close to the spherical section, and a screw section is formed on the third shaft section. Subsequently, a heat treatment is performed to remove the residual stress from the formed components concurrently with increasing the strength and improving the ductility. Finally, a coating is made for rust prevention. The boot groove is made to have an uneven configuration.

摘要： An internally toothed member is shown suitable for use as a clutch drum in an automatic transmission. The internally toothed member has the shape of a cup with an open end and a central axis. The cup-shaped member has first internal teeth extending in the axial direction and second internal teeth extending further toward the open end of the member than the first internal teeth. The internal teeth are each formed on an inner circumferential surface of the cup-shaped member in each of a plurality of locations spaced in the circumferential direction. Also, a groove for receiving a snap ring is formed in the second internal teeth closer to the open end than end faces of the first internal teeth facing the open end. Because the first and second internal teeth are formed projecting radially inward, they do not lower the rigidity of the internally toothed member. Also, because it is not necessary to fix a cylindrical member to the outside of the internally toothed member for reinforcement, working man-hours can be reduced and it is possible to lower the cost of the internally toothed member.
