| 21 | COMPOSITE BRAKE DISC AND METHOD AND APPARATUS FOR MANUFACTURE OF THE SAME | US15027293 | 2014-10-22 | US20160238095A1 | 2016-08-18 | Daniel Dériaz |
| With the method for manufacturing a composite brake disc, which includes a brake disc chamber and a friction ring having an inner profiling, a brake disc chamber blank is introduced into the friction ring. The brake disc chamber blank is then formed into the inner profiling via at least one embossing tool. A composite brake disc permitting a good torque transmission between the friction ring and the brake disc chamber can be manufactured in a cold-forming manner in this way. The forming-in can take place in a hammering manner, in particular by successively implementing a plurality of embossing steps in the region of different profile gaps of the inner profiling. Axial stops can also be simultaneously produced on forming-in. The axial stops serve to stop the brake disc chamber and the friction ring (3) are prevented from axially sliding apart. | ||||||

| The present invention relates to a system for and a method of manufacturing a linear gear (rack gear), in which a forming roll and a guide roll are used to form gear teeth in a sequential manner so as not to require a high load, thereby enabling to easily manufacture the rack gear. A system for manufacturing a rack gear according to the invention includes a forming roll having a convexo-concave portion formed on a part of the surface contacting with a linear bar, a guide roll adapted to roll while facing the forming roll, and at least one support member for supporting the linear bar so as to allow the linear bar to linearly move. A method of manufacturing a rack gear according to the invention includes a first step of passing a linear bar through between a pair of rollers provided in front of a forming roll and a guide roll, a second step of charging the linear bar into a charging hole between the forming roll and the guide roll, a third step of rolling the forming roll and the guide roll to partly form teeth on the outer circumferential surface of the linear bar, and a fourth step of rolling the forming roll and the guide roll forward or backward to discharge the linear bar. | ||||||

The front end face of an advancing blank engages the teeth of the masters in the region of the larger-diameter ends of cones formed by the crowns of teeth on the masters and the outer diameters of annuli of teeth or splines formed by the masters exceed the diameters of the blanks. The masters are adjustable radially and/or angularly with reference to the axes of the blanks.

CONSTITUTION: In this manufacturing method, a core metal 26 is inserted into the inner part of a hollow pipe-like rack shaft blank 11, and the rack shaft 11 and a form-rolling roll are relatively slid to form the rack teeth 12 on the rack shaft blank 11. The core metal 26 whose cross sectional shape has a working supported surface 90 being apart from a predetermined rack tooth shaping part of the rack shaft blank 11 through a gap and working supported surface 90 is high at the middle part is used.
