Abstract

662,769. Grinding non-circular profiles. MUSYL, R. Jan. 17, 1949 [Jan. 24, 1948], No. 1272/49. Class 60 A device for producing non-circular profiles, particularly those on cams, in which a grinding process is effected in such a manner that the centre of the grinding wheel is always situated on the normal to the profile at the point where the latter makes contact with .the grinding wheel, is characterized in that two master cams are provided which control the movements of the tool by means of movable elements. The work 19 is rotated at a constant angular velocity by a synchronous motor while a compound motion is imparted to the grind. ing wheel 3 by two co-axial cams 1, 2 also driven by a synchronous motor in timed relation with the work. The cam 2 produces vertical movement of the grinding wheel through a lever 5 having a fixed pivot 4, while the cam 1 produces horizontal movement through a slide 13. The latter bears on a roller 15, which together with the grinding wheel is journalled at the end of a lever 7 pivoted to the free end of the lever 5 and biassed by a spring 16. Pulleys 21, 22, and 23 are provided for the belt drive to the grinding wheel from a motor 20 which is fixedly mounted on the machine frame. Shafts with a number of cams may be ground in a machine such as that shown in Fig. 10. The camshaft is supported between a headstock 41 and a tailstock 42 mounted on an adjustable table while each grinding unit is adjustable in both the longitudinal and transverse directions of the camshaft. A change-speed device for each grinding wheel is provided, and a number of pairs of master cams may be arranged on a shaft which can be adjusted axially by a handwheel 39 to bring the required pair into operation.
