Patent number: 11585377Abstract: A holder has a protrusion which protrudes from a side surface at a side opposite in an axial direction with respect to a rolling element held in a pocket toward the side opposite in the axial direction. An oil supply hole which penetrates through the holder from the side surface to a surface at a side of the rolling element in the axial direction is formed in the holder. When the holder rotates, the protrusion guides oil into the oil supply hole, and the oil is introduced from the side surface of the holder to the surface on the side of the rolling element.Type: GrantFiled: March 1, 2022Date of Patent: February 21, 2023Assignees: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, JTEKT CORPORATIONInventors: Mamoru Tohyama, Yasuhiro Ohmiya, Norikazu Sato, Michiru Hirose, Takaaki Onizuka, Yoshio Tateishi, Kenichi Hasegawa, Takuya Toda, Komatsugu Nishimura, Yuya Yamamoto

Publication number: 20150083655Abstract: Provided is an oil deterioration prevention device with which the trapping effect with respect to oil deteriorated components can be improved and with which the oil passage resistance can be reduced, thereby suppressing a rise in pressure loss. This oil deterioration prevention device is equipped with a filter unit equipped with a filter material that filters oil; and a deterioration prevention unit equipped with a powdery deterioration suppressing agent that suppresses oil deterioration. The deterioration prevention unit contains a mesoporous inorganic material, and of the oil fed from an oil storage unit, the oil filtered by the filter unit is fed to parts which are to be lubricated, and the oil in which deterioration has been suppressed by the deterioration prevention unit is returned to the oil storage unit or is fed to the parts to be lubricated.Type: ApplicationFiled: April 30, 2013Publication date: March 26, 2015Applicants: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventors: Hideto Morishita, Yasuhiro Saito, Ippei Fukutomi, Motoichi Murakami, Katsuichi Miyasaka, Yasuhiro Ohmiya, Hiroshi Moritani, Mamoru Tohyama, Narihito Tatsuda
