Patent number: 9593720Abstract: A motor includes a motor body, a pin, a core, and an input cam. The motor body includes a housing and an output shaft. The pin is arranged in the output shaft to extend in a direction orthogonal to a rotation axis of the output shaft. The core is pivotally supported by the pin and rotates coaxially with the output shaft. The input cam is annular and surrounds an outer circumference of the core. The input cam rotates integrally with the core. An end surface of the core closer to the housing includes a first deviated surface. The core includes an insertion portion into which the pin is inserted. When a center axis of the core is coaxial to the rotation axis of the output shaft, the first deviated surface is located at a position farther from the housing than the insertion portion.Type: GrantFiled: March 6, 2015Date of Patent: March 14, 2017Assignees: ASMO CO., LTD., Denso CorporationInventors: Yoshiyasu Inoue, Nobuhiro Matsumoto, Masanori Ozaki, Hirokazu Tajima, Masaru Irie, Taei Sugiura

Patent number: 9103242Abstract: A planetary carrier supports a geared rotor from an inside in a radial direction, and receives a radial load in a first region, which is offset to one end from a center position in an axial direction. A ball bearing roller supports the planetary carrier from an outside in the radial direction in a second region, which is offset to an other end from the center position. The ball bearing roller is a single-row ball bearing roller that has an outer ring supported by a drive rotor, an inner ring which supports the planetary carrier, and a plurality of rolling elements which are rotatably installed in a single row to be in contact with and between the outer and the inner rings. The geared rotor is tilted relative to the axial direction, and contacts a driven rotor in the axial direction. An angle of the geared rotor relative to the axial direction is set to be smaller than a maximum allowable angle at which the inner ring is allowed to be tilted relative to the axial direction.Type: GrantFiled: June 12, 2014Date of Patent: August 11, 2015Assignee: DENSO CORPORATIONInventor: Taei Sugiura
