The magnetizing yoke includes a base; a set of first segmented cores disposed on the base in a circumference, each of first segmented cores having a recess portion open inward in a radial direction corresponding to the circumference; a set of coil cartridges disposed inside the set of first segmented cores in the radial direction; and a set of positioning members positioning the set of coil cartridges relative to the base. Each of the coil cartridge includes: an insulator having a pair of walls facing each other in the radial direction; a coil disposed between the pair of walls; and a second segmented core including a protrusion received in the recess portion. The insulator, the coil, and the second segmented core are integral with each other. The set of positioning members prevent the set of coil cartridges from moving inward in the radial directions respectively. Each of coil cartridges is detachable from an assembly of the base, a first segmented core, and a positioning member.

Magnetizing yoke

A center shaft machining apparatus includes: a grinding structure that moves on a machining central axis while rotating about the machining central axis and machines an end surface on one end side of a workpiece arranged on the machining central axis; an end portion support structure that supports an opposite end side of the workpiece; and a shaft portion support structure that supports a shaft support portion set at an intermediate portion of the workpiece. The end portion support structure includes an eccentric mechanism capable of supporting an opposite end of the workpiece in a state where a workpiece central axis of the workpiece is eccentric with respect to the machining central axis.

Center shaft machining apparatus

A magnetizing yoke prevents coils from being damaged and/or broken when an object to be magnetized is magnetized, more securely as compared with any conventional arts. The magnetizing yoke includes a slot member made of thermoplastic resin and formed with slots for inserting and fixing windings of an iron core, wherein the slot member is inserted into and fixed to the iron core. The magnetizing yoke is manufactured using a simple step of mounting the slot members made of resin on the iron core.

Magnetizing yoke and manufacturing method thereof

This backlash measurement device measures the backlash existing between a first part and a second part that is provided with: a left pressing piece (L) and a right pressing piece (R) that rotate together with the second part, that pass through the center of rotation (), and that extend the same distance from the center of rotation; a left pressing mechanism (L) that presses the left pressing piece and a right pressing mechanism (R) that presses the right pressing piece; a displacement amount detection mechanism () that comes into contact with the right pressing piece and that measures the displacement amount of the left pressing piece and the displacement amount of the right pressing piece; and a calculation unit () that determines backlash on the basis of the left displacement amount and the right displacement amount detected by the displacement amount detection mechanism.
