摘要： PROBLEM TO BE SOLVED: To reduce driving torque of a rotary pump.
SOLUTION: A curvature of an arc comprising a side 72da of a suction groove 72d is made larger than that of an arc comprising a side 72ea of a discharge groove 72e. Thereby, when the suction groove 72d and the discharge groove 72e are viewed from the axial direction of a drive shaft 54, in the radial direction of a rotating part, a distance between the suction groove 72d and the discharge groove 72e is short in a portion intersecting a line W vertical to a center line Z and becomes longer as separating from the portion and approaching to closed part 53a, 53b. Therefore, the distance between the suction groove 72d and the discharge groove 72e can be increased, and total fluid pressure generated between the grooves 72d, 72e can be enhanced. In addition, contact surface pressure of an outer rotor 51 and an inner rotor 52 in a second side plate 72 necessary for obtaining reaction force is reduced, and driving torque of the rotary pump can be reduced.

摘要翻译：要解决的问题：减少旋转泵的驱动转矩。解决方案：使包括吸入槽72d的侧面72da的弧的曲率大于包括排出槽72e的侧面72ea的电弧的曲率。因此，当从驱动轴54的轴向观察吸入槽72d和排出槽72e时，在旋转部的径向方向上，吸入槽72d和排出槽72e之间的距离在部分与垂直于中心线Z的线W相交，并且随着与该部分分离并接近闭合部分53a，53b而变长。因此，能够提高吸入槽72d与排出槽72e之间的距离，能够提高槽72d，72e之间产生的总流体压力。此外，减小了获得反作用力所需的第二侧板72中的外转子51和内转子52的接触面压力，能够降低旋转泵的驱动转矩。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To suppress the deformation caused by welding in the whole periphery of a cylindrical member such as a gear pump P. SOLUTION: In the gear pump in which an inner rotor and an outer rotor are disposed inside casing 10, and the casing consists of circumferential casing covering the outer circumferential face of the outer rotor and side casing covering both the sides of the outer rotor and the inner rotor, all around the circumferential side edges on both the sides in the circumferential casting is subjected to welding (t) to the periphery of each side casing. The welding is performed from a section (c) turned by 90 degrees to the peripheral direction from the center of two notch (holes) 11 for loading sliding seals. In the welding for the welding starting point (c) and the notch parts 11, the force to deform the casing 10 into an elliptic shape works by the solidification thereof, but the solidification force is deviated by 90 degrees to cause canceling, so that its deformation is suppressed.

摘要： PROBLEM TO BE SOLVED: To permit measurement of coaxiality in a short time, which relates to a coaxiality measuring device.
SOLUTION: The coaxiality measuring device is provided with: a rotational mechanism 3 for rotating a workpiece 1 to prescribed rotational positions in order; a first sensor 41 for measuring the radial position of the outer circumferential surface in a first cylindrical part 11; a second sensor 42 for measuring the radial position of the outer circumferential surface in a second cylindrical part 12; and a computational means 6 for calculating the coaxiality of the first cylindrical part 11 and the second cylindrical part 12, on the basis of the rotational position data from the rotational mechanism 3 and the measurement data of the first and second sensors 42. Because the first cylindrical part 11 and the second cylindrical part 12 can be simultaneously measured, the coaxiality can be measured in a short time.

摘要： PROBLEM TO BE SOLVED: To make heat radiation possible while operating a rotary pump, not stopping the rotary pump completely. SOLUTION: When driving a trochoid pump, the timing that a sealing member is pressed against an outer gear and an inner gear and the timing that the sealing member is not pressed against the outer and inner gears are set. In other words, the timing that frictional heat is generated in spite of sealing properties between the outer and the inner gears and a second side plate being secured and the timing that heat radiation can be performed in spite of the sealing properties being unable to be secured are switched with each other. Thus, the trochoid pump can be kept driving, and the operation of a braking device is made possible to continue. Thus, improvements in the performance of the braking device can be made possible.

摘要翻译：要解决的问题：为了在操作旋转泵时进行散热，不能完全停止旋转泵。解决方案：当驱动次摆线泵时，设置密封构件压靠外齿轮和内齿轮的时间以及密封构件未被压靠外齿轮和内齿轮的时刻。换句话说，尽管固定有外齿轮和内齿轮之间的密封性能以及即使不能确保密封性能也可进行热辐射的时刻，摩擦热产生的时刻彼此切换。因此，能够维持等速摆线泵的驱动，能够使制动装置的动作持续。因此，能够提高制动装置的性能。版权所有（C）2006，JPO＆NCIPI
