The motor case covers an outer periphery of the motor housing and is coupled to the transmission case. The seal member is between the motor case and the motor housing and isolates the wet space and the outer space. The motor housing is divided into a divider wall housing dividing off the wet space and an outer wall housing dividing off the outer space, the divider wall housing being a material lighter than a material of the outer wall housing and integrally coupled thereto. The divider wall housing is divided from the outer wall housing at a position nearer to the dry space than the seal member. | 02-05-2015 |
20150075311 | ACTUATOR AND METHOD FOR MANUFACTURING THE SAME - A housing accommodates a motor and a deceleration mechanism. The deceleration mechanism includes a support axis extending perpendicularly to an output shaft of the motor. The housing includes a case and a cover. The case is in a bottomed tubular shape to have an accommodation chamber and a holder portion. The holder portion surrounds a bottom of the accommodation chamber and is in contact with the motor. The cover is mounted to the case to surround an opening of the case and to form a hollow portion with the holder portion to accommodate at least the motor. The motor and the deceleration mechanism are mountable into the accommodation chamber through the opening in one direction from a side of a mounting surface of the case, on which the housing is to be affixed to a support portion of an affixing member. | 03-19-2015 |
20150128739 | DRIVING DEVICE FOR WASHING MACHINE - Disclosed is a driving device for a washing machine including a bearing housing affixed to a lower surface of a tub; a spin-drying shaft that extends through the bearing housing, having an upper end coupled with a drum, and having a serration at an outer circumferential edge of a lower end; a washing shaft that extends through the spin-drying shaft so that opposed ends of the spin-drying shaft extend beyond and end of the washing shaft, having an upper end coupled with a pulsator or agitator, and having a serration or gear a lower end; a driving unit configured to deliver power to rotate the spin-drying shaft and/or the washing shaft; and a driving unit support part having one end coupled to the bearing housing and another end fastened with the driving unit. | 05-14-2015 |
