摘要： A sealless-type centrifugal pump includes a casing that forms a pump chamber having a liquid inflow port and an outflow port, an impeller disposed in the pump chamber and rotatably supported by a pivot bearing, and a magnetic coupling device including a driven permanent magnet built into the impeller and a driving magnet that rotationally drives the driven permanent magnet through a partition. The impeller supported in the direction of the rotation axis with respect to the casing is driven by the magnetic coupling device, and pressure is applied to liquid introduced from the direction of the rotation axis through the inflow port to send the liquid through the outflow port in a radial direction. The magnetic coupling device is disposed on a line inclined from an impeller rotating surface to the inflow port side toward the center of the rotation axis.

The centrifugal pump includes a casing that forms a pump chamber having a liquid inflow port and an outflow port, an impeller disposed in the pump chamber and rotatably supported by a pivot bearing, and a magnetic coupling device including a driven permanent magnet built into the impeller and a driving magnet that rotationally drives the driven permanent magnet through a partition. The impeller supported in the direction of the rotation axis with respect to the casing is driven by the magnetic coupling device, and pressure is applied to liquid introduced from the direction of the rotation axis through the inflow port to send the liquid through the outflow port in a radial direction. The magnetic coupling device is disposed on a line inclined from an impeller rotating surface to the inflow port side toward the center of the rotation axis.

摘要： A rotating shaft is supported by journal bearings that can support without contacting the rotating shaft itself. Then, one end of both shaft end portions of the rotating shaft has a main impeller installed and the other end is provided with a sub impeller. By utilizing a force being generated by rotation of the main impeller, liquid being pumped (fluid being pumped) is sucked in through a suction port and discharged through a discharge port. On the other hand, by utilizing a force being generated by rotation of the sub impeller, fluid is transported to the journal bearings, thereby having the journal bearings support the rotating shaft.

摘要： A ball screw mechanism including a screw shaft with a screw groove formed on an external surface, a nut with a screw groove formed on an internal surface, and plural balls held in the grooves. A ball circulation piece is fit in a window portion in the nut and has a circulation groove for circulating the balls. The screw groove of the nut and the circulation groove are machined by moving a tool of a diameter equal to or larger than the diameter of the balls, along the screw groove of the nut so that a step is eliminated at a joint therebetween. The infeed depth of the tool is gradually changed as the tool is moved toward the joint so that boundary lines between a machined surface and a non-machined surface on flanks of the screw groove of the nut extend at an acute angle to one another.

摘要： An electric power steering apparatus comprises a rack-and-pinion mechanism and a ball screw mechanism. The ball screw mechanism comprises a shaft formed a screw groove and a nut formed a screw groove. A ball-roll path is created spirally by the screw grooves of the shaft and the nut being opposite each other. A plural number of balls are contained into the ball-roll path. A ball-return path is connecting both ends of the ball-roll path so that the balls go through. A circulation path consists of the ball-roll path and the ball-return path, in which the balls move endlessly. A plural number of separators is arranged between the balls respectively in order to prevent balls from contacting each other. A number of the balls is fewer from one ball to three balls than a maximum number of the balls which can be contained into the circulation path.
