1377106 Bearings TOYO BEARING MFG CO Ltd 29 Aug 1972 [6 Sept 1971 17 Nov 1971 18 Nov 1971] 39944/72 Heading F2A Apparatus for automatically assembling rolling bearings comprises a measuring part which measures the difference in the groove diameters of inner and outer race rings and determines the size of rolling elements suited to said rings, a part which when a measured pair of rings arrives at the assembling position, feeds said pair with rolling elements suited in size thereto, and an electric memory part interconnecting said two parts which stores information as to element size in the order in which said pairs of rings are measured. Measuring race rings (Fig. 1).-Inner and outer rings roll down respective shoots 1, 2 to groove-measuring devices 3, 4, the measured valves being transmitted to an arithmetic unit 5. The rings are then paired by mechanism 8 and stored as paired units in shoot 9. The memory circuit 10 stores output signals from the unit 5 in order of measurement taken, and controls the operation of a rolling element supply device 11, 12. Supplying rolling elements (Fig. 3).-Rolling elements are stored according to size in bins 11a, which are radially arranged on a table 14. Each bin supplies elements by means of a verticallyreciprocating sleeve 17 to a respective elementcounter 12a, which can accommodate a certain predetermined number of elements, and can be reciprocated by means of a piston and cylinder 12b between positions for receiving elements from pipe-line 16 and discharging them through a common pipe-line 18 situated at the centre of the ring of counters. The operation of the appropriate piston and cylinder is controlled by a signal from the memory circuit in accordance with the dimensions of the next pair of rings to be filled with elements. The elements of the appropriate size are temporarily stored in a store 19 until the operation of a further piston and cylinder 13b causes them to be discharged from a device 13a into an eccentric clearance created between the race rings of the appropriate pair.
