Abstract
1367488 Trueing grinding wheels SKF (UK) Ltd 10 Oct 1972 [9 Sept 1971] 42161/71 Heading B3D A method of dressing the periphery of a grinding wheel 10 to provide it with a profile comprising two convex circular arcs 37 with a valley therebetween comprises moving a dressing tool 35 across the periphery in a direction parallel to the axis of rotation of the wheel and, at the same time, towards and away from the axis by means of two arms 21, 22 which pivot in succession about fixed abutments 29, 30 as the tool is moved across the periphery. The dressing mechanism has a base 15 which is slidably mounted on the bed of the grinding machine for movement towards and away from the grinding wheel which is arranged for grinding the tracks on the inner ring of a bearing heaving a double row of part-spherical rollers. A primary carriage 16 is movable by an actuator parallel to the axis of the grinding wheel on the base 15 and supports a secondary carriage 18 movable perpendicularly to the axis, the carriages sliding on re-circulating ball slides. A dressing tool 35, which may be a diamond-pointed tool or acutting wheel rotated by a flexible drive shaft 36 is mounted on a holder 19 on the secondary carriage which also mounts a pivot 20 for the lever arms 21, 22 swingable about an axis 26. The secondary carriage is spring-biased towards the grinding wheel and to a position determined by engagement of an abutment with a stop adjustable by a micrometer screw 24. The arms are adjustable in length by screws 33, 34 and are fixed to one another at a set angle. The ends of the arms have part-spherical ends 27, 28 for engagement with respective abutments 29, 30 on the base 15, the abutments being adjustable in a direction parallel to the axis of the grinding wheel by screws 31, 32. During dressing, the arm 22 is initially out of engagement with the abutment 30 and the secondary carriage. During the movement the processing carriage 16 moves in a circular arc under the control of arm 21 and abutment 29 so that the tool 35 forms the first are from point A. At the end of the first arc, the abutment 25 is engaged by the stop 23 so that the dressing tool moves parallel to the axis of the wheel to dress a cylindrical portion until the arm 22 engages the abutment 30 and the secondary carriage, and hence the tool, is moved to dress the second circular arc on the wheel up to the point B. In another embodiment, the arms 21, 22 are telescopic between their ends 27, 28 and the pivot 26 and their length is governed by internal stops.
