摘要： An auxiliary equipment for valve grinding is provided, including a main body, a driving shaft, a first linkage, a second linkage, a third linkage and a driven shaft. The driving shaft defines a first axial direction. The driving shaft is for connecting to a rotating tool. One end of the first linkage is connected to the driving shaft. The second linkage and the other end of the first linkage are connected to a first movable connecting portion. One end of the third linkage and the second linkage are connected to a second movable connecting portion. The driven shaft defines a second axial direction. When the first linkage rotates together with the driving shaft, the first movable connecting portion rotates about the first axial direction, the second linkage swings about the first movable connecting portion, and the second movable connecting portion swings about the second axial direction.

摘要： In forming a helical gear by grinding with a grindstone, the modification accuracy of crowing etc. is improved in such a way that the inequality .beta.>.gamma. c is established wherein .beta. is the helix angle of the helical gear to be ground and .gamma. c is the inclination angle of the grindstone, and the profile of the grindstone is designed to have a vertical angle which is equal to the inclination angle (.gamma. c)of the grindstone.

摘要： An apparatus for the precision grinding of conical valve seats of nozzles, for example, injection nozzles for internal combustion engines. The body is entered hydraulically on a mandrel and a driver has a rubber O-ring braced against the nozzle body to frictionally engage it is rotation while passing through the mandrel for the shaft of a grinding tool which is located at the end of the mandrel. The system avoids radial clamping stresses on the workpiece and hence allows, precision low tolerance finish grinding to be achieved.
