Title: Cylindrical linear motor and manufacture of cylindrical linear motor
Inventor: TOMOSUGI HIROYUKI
IPC: B60G11/00
Filed: 1995-05-19
Abstract: PURPOSE: To decrease the fluctuation of thrust without lowering the thrust of a linear motor. CONSTITUTION: Pole bodies 9, wherein a plurality of permanent magnets held with magnetic substances 8 from the upper and lower sides, are laminated in the axial direction, and an inner rod 2 is formed. The inner rod 2 is coupled into an outer tube 5, which is formed by laminating electromagnets 16 constituted by coupling coils 27 into slots S of magnetic substances 26, so that the rod is freely moved in the axial direction. In this linear motor 6, a thin cylindrical inner casing 18 comprising a magnetic substance is fixed to the inner side of the electromagnets 16. Thus, the closed magnetic path surrounding the electromagnets 16 is formed. Furthermore, a thin cylindrical gap-forming member 28 comprising a nonmagnetic substance is fixed to the inner surface of the inner casing 18.  The inner rod 2 is brought into contact with the inner surface of the member 28 so that the rod 2 is freely slid. Thus, the fluctuation of the gap caused by the eccentricity of the inner rod 2 and the outer tube 5 is prevented.

Abstract: PROBLEM TO BE SOLVED: To lubricate the power roller of a toroidal transmission unit during vehicular towing and to materialize lubrication by using an existing power roller lubricating oil path as its oil path. SOLUTION: As shown in (a), hydraulic oil is discharged from an oil pump, O/P, during engine operation. A valve body 37 uses the hydraulic oil as a medium for transmission control. The spent hydraulic oil for lubricating a power roller 8 (9) is cooled by means of an oil cooler 45 and is then exhausted to the power roller 8 (9) through a pipe 46 oil holes 43, 42 from an exhaust hole 41. As shown in (b), during vehicular towing, an elevation in the oil level of an oil pen evolves a gear 20-immersing hydraulic oil reservoir. Output gear sets 20-22 scratch up the hydraulic oil reservoir for storing an oil reservoir 52. As shown in an arrow mark in (b), gravitational force from the oil reservoir 52 directs the stored oil for lubricating the power roller to the power roller through the oil holes 43, 42, and the exhaust hole 41 with a check valve 55 opened.
