摘要： In general, in a metallic Oldham coupling, the transmission of a rotational force between a pair of rotary shafts cannot be carried out accurately due to the existence of a clearance. According to the present invention, an Oldham coupling body (18) is molded of a resin, and the end portions (12A, 12B) of rotary shafts (10A, 10B), i.e. members to be coupled are respectively engaged with recesses (30, 32). Since the widths (LY, LX) of these recesses vary greatly with temperature, the variations of the widths are restricted by a metallic size restriction member (16). In order to prevent respective clearances from occuring in the longitudinal direction (Z) of the rotary shafts and in the direction of the depth of the recesses (30, 32) between the end portions (12A, 12B) of the rotary shafts and the recesses, a pressing force is applied constantly in the longitudinal direction (Z) by spring members (14A, 14B) provided there between.

摘要： If a pulse encoder having a plurality of absolute-type slits (24, 26, 28, 30) and a plurality of increment-type slit groups (14, 16, 18, 20) has a structure wherein the shape of each increment-type slit group is rectangular, it is impossible to irradiate both of these groups and the absolute-type slits with one light-emitting element (46). To solve this problem in this invention, the increment-type slit groups are formed each in a sectorial shape and are radially arranged about the optical axis (13) of the light-emitting element (46). It becomes thus possible to arrange the absolute-type slits (24, 26, 28, 30) in the remainder of a region (12) irradiated with the one light-emitting element (46) and, hence, to provide a pulse encoder which is compact at a low cost.

摘要： This invention relates to a structure for fixing a rotor (12), in which rotor cores (16) and magnets (14) are arranged alternately in the circumferential direction, of a synchronous motor to an output shaft (10). A molding resin (24) is packed in a clearance between the inner circumferential surface of the rotor (12) and the outer circumferential surface of the output shaft (10) and hardened, whereby these two structural elements (10, 12) are combined with a high reliability to enable the bending rigidity of the output shaft (10) to be increased.

摘要： A permanent magnet field rotor assembly with a rotor shaft (11). Around the rotor shaft, a plurality of yokes (12), which extend in the axial direction of the rotor shaft, are arranged so that the yokes are spaced from one another in the circumferential direction of the rotor shaft. The permanent magnets (13) extending in the axial direction of the rotor shaft are held between two adjacent yokes. A pair of end plates (14, 15) attached to both end portions of each yoke consist of a non-magnetic material. Bosses (14a, 15a) which can be fitted around the outer circumferential surface of the rotor shaft are formed at the central portions of the end plates. The bosses of the end plates are fixed to the outer circumferential surface of the rotor shaft by the tightening force of shrunk rings (18, 19) set on the outer circumferential surfaces of the bosses by shrinkage fit.
