20160082570 | METHOD AND TOOL FOR INCREASING THE STRENGTH OF SHAFTS, IN PARTICULAR OF CRANKSHAFTS - A method and compression roller tool for increasing the strength of load-bearing surfaces on shafts, in particular on crankshafts, which surfaces are pre-machined with the removal of chips, wherein the cylindrical surfaces of the main bearing journals and pin-bearing journals and optionally also the journal of crankshafts have additional oil bores. At least one of the load-bearing surfaces is compression-rolled by way of at least one cylindrical body which has a surface structure and extends over the width of the load-bearing surface. Afterwards, the compression-rolled load-bearing surfaces are machined with the removal of chips with a low chip depth. The compression roller tool consists of a cylindrical compression roller body and a supporting body opposite it, wherein the compression roller body has thickened portions on its cylindrical surface, which thickened portions run either in the circumferential direction or in the axial direction or diagonally with respect to the axial direction. | 03-24-2016 |
20150239480 | METHOD AND DEVICE FOR INSPECTING RAILWAY WHEELS - The present invention concerns a method and a device for inspecting railway wheels with respect to use-related wear and/or a material defect. The task of the present invention is to create a technical solution in this regard by means of which various configurations of railway wheels can be tested in a short time. In particular, an inspection should be carried out in override mode so that the test results for a complete train can be prepared during the passage time over an allocated test device. This task is accomplished in that the rolling railway wheelset passes through a spatially restricted magnetic field that is coupled through the rails along which the allocated rail vehicle is guided. For this purpose, a device is used in which an electromagnet ( | 08-27-2015 |
20150074998 | METHOD FOR IMPROVING THE QUALITY OF THE SURFACES OF CRANKSHAFTS - The invention relates to a method for machining surfaces of the bearing seats of main and pin bearings on crankshafts made of cast steel following the machining of surfaces with an undefined cutting edge by grinding or finishing. The problem of improving the quality of the running surfaces of the bearings of hardened or unhardened crankshafts is solved. This is achieved by irradiating the surfaces with a laser beam. | 03-19-2015 |
