摘要： A cross shaft joint (6) includes a bearing cup (24), a cross shaft (23), and a joint yoke (20). The bearing cup (24) includes a cylindrical portion (48) in which an opening portion (50) for receiving a shaft portion (46) is formed in one end of the bearing cup in an axis direction, and a bottom portion (49) that closes the other end of the cylindrical portion (48) in the axis direction. The bearing cup (24) is press-fitted into the fitting hole (31,42) and supports the shaft portion (46) through a rolling element (53) so that the shaft portion (46) is able to rotate. The bearing cup (24) is fitted onto the shaft portion (46) inside the fitting hole (31, 42) and holds the rolling element (53) with the shaft portion (46). A diameter of an inner peripheral surface (48A) of the cylindrical portion (48) is smaller on the opening portion (50) side than the bottom portion (49) side in a free state of the bearing cup (24) before being press-fitted into the fitting hole (31, 42).

摘要： In effecting two-sided surface grinding for surface-grinding the opposite surfaces of a workpiece (17) simultaneously by a pair of oppositely disposed grinding wheels (12) and (13), infeed grinding is performed by oscillating the workpiece (17) within the range where the surfaces to be ground (17a) of the workpiece (17) do not stick out from the inner and outer peripheries of the grinding wheel surfaces (12a) and (13a) of the grinding wheels (12) and (13), and then through-grinding is performed by feeding the workpiece (17) to allow the surfaces to be ground (17a) to pass along the inner and outer peripheries of the grinding wheel surfaces (12a) and (13a). As a effect, worn wheel edges or the like can be prevented from being formed in the inner and outer peripheral edges, that grinding wheel surfaces can be maintained in proper shape for a prolonged time, that the grinding accuracy is better, and that dress interval can be prolonged, thus improving the life of grinding wheels.

摘要： Detecting the deviation of the grinding wheel position from the amount of work deformation after grinding, and correctly adjusting the grinding wheel position, it provides both-side grinding techniques for making the work excellent in flatness and parallelism.
When the feeding operation of grinding wheels (1, 2) is completed, the distances from hydrostatic pads (20, 21) to the surface and back of work (W) are measured at three points, and the deformation amount of work (W) is detected from the results of measurement at the three points by using air gauge sensors( Sa, Sb, Sc), and in case the calculated amount of deformation exceeds the specified value, the moving adjustment of grinding wheels (1, 2) is performed in accordance with the amount of deformation so that work (W) is flat without deformation when the feeding operation of grinding wheels (1, 2) is completed.

摘要： A high efficiency centerless grinding method capable of grinding the tip portion of bar-shape work, assuring high coaxiality and cylindricity even in case of work having extremely small diameter. The base portion (Wa) of work (W) is pressed and supported by pressure roller (4) against regulating wheel (2), forcibly rotating the work (W), and the work (W) is fed by pusher (5) in the axial direction in order to grind the tip portion (Wb) of work (W) by grinding wheel (1). In this way, even when the tip portion (Wb) of work (W) is extremely small in diameter, the lengthwise grinding of the work (W) may be accurately controlled, and the tip portion (Wb) of work (W) is ground in accordance with the diameter of the base portion (Wa) . As a result, it is possible to grind the work (W) into a stepped work (W) in a short time with little deflection in axial center of the work (W) while assuring high coaxiality and cylindricity.

摘要： A speed-increasing spindle device comprises a device main body (1) and shank (2), capable of using a coupling bolt (41) of large diameter, high rigidity, and sufficient strength. The head (41 a) of the coupling bolt (41) is rotatably engaged in a bolt head engaging part (42) provided at one side of the device main body (1) and shank (2), while the threaded part (41b) of the coupling bolt (41) is engaged with a screw hole (43) provided at the other side of the device main body (1) and shank (2). An engaging part (5a) for a rotary operation tool is provided on an outer end plane in the axial direction of the coupling bolt (41) and addresses the outside through the insertion hole (58) of the shank (2). The bolt head engaging part (42) has a bolt head accommodating space (56) larger than the maximum hole diameter permitted in the shank (2) in terms of strength, and therefore the shaft diameter of the coupling bolt (41) may be set, at least, as large as the maximum hole diameter of the shank (2).
