Publication number: 20120240706Abstract: A ball return channel of a ball screw is formed within a nut and a ring-shaped non-contact seal is arranged at the axial both ends of the nut. A suction hole radially penetrating the nut is formed within the range of a raceway (a rolling channel formed by a spiral groove of the nut and a spiral groove of the screw shaft). This guarantees not to emit dust produced inside the nut, and attains dust reduction effect higher than that of the conventional ball screw.Type: ApplicationFiled: October 29, 2010Publication date: September 27, 2012Applicant: NSK Ltd.Inventors: Tsutomu Ohkubo, Kazuhito Yamamoto

Publication number: 20120144944Abstract: A ball screw apparatus is provided which is less likely to increase dynamic friction torque even when a nut is contracted by cooling, and in which cooling effect is made as high as possible and which does not invite excessive machining efficiency droop and increase in pressure loss. The ball screw apparatus includes a screw shaft, a nut screwed with the screw shaft via a plurality of balls, and a cooling section cooling the nut. The plurality of balls to which preload is applied in a two-point contact state, with a preload direction as a tensile direction, are disposed between a screw groove of the screw shaft and a screw groove of the nut. Or, a ratio of the axial length L of the through hole axially formed in the nut and the diameter D of the through hole axially formed in the nut is given by an equation “10?L/D?60”.Type: ApplicationFiled: August 25, 2010Publication date: June 14, 2012Applicant: NSK LTD.Inventors: Kazuhito Yamamoto, Junji Minakuchi, Yutaka Nagai, Masahiro Nobutomo

Publication number: 20120043741Abstract: A side airbag has a high-pressure chamber and a low-pressure chamber with a pressure lower than the pressure in the high-pressure chamber. An inflator is provided in the low-pressure chamber with a gas discharge section facing the high-pressure chamber. In a side collision, gas from the inflator is supplied mainly toward the high-pressure chamber and is supplied also to the low-pressure chamber. The high-pressure chamber and the low-pressure chamber are partitioned by a partition wall. A check valve mounted to the partition wall is opened by the pressure gas supplied from the inflator, which is provided in the low-pressure chamber, toward the high-pressure chamber, and thus the cheek valve permits the gas to flow from the low-pressure chamber to the high-pressure chamber. When the inflator completes the discharge of the gas, the check valve restricts such flow of the gas from the high-pressure chamber to the low-pressure chamber.Type: ApplicationFiled: May 11, 2009Publication date: February 23, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Kazuhito Yamamoto
