摘要： A shaft 3 of bearing steel is formed with a number of inclined grooves 20. An annular member or pulley seat 5 of lower hardness than the shaft 3 is press fitted thereon so that the material of the annular member 5 protrudes into the grooves 20. A rust-preventing oil is applied to the shaft 3 before fitting to improve the joint, and generally remains after fitting. The joint is suitable for connecting a shaft of an automobile water pump to a fan pulley seat 5 as shown. … …

摘要： PROBLEM TO BE SOLVED: To suppress the deterioration in sealing performance of a mechanical seal provided to a shaft sealing part in a fluid pump with a mechanical seal which is maintained in a state that a shaft provided with an impeller for fluid pressurization and rotationally driven by external power source eccentrically rotates.
SOLUTION: The fluid pump (water pump) is equipped with a shaft 2 provided with an impeller 4 for cooling water pressurization and rotationally driven by an engine output shaft, and with a mechanical seal 6 for sealing a shaft sealing part through surface contact followed by a mating ring 63 supported by a rotation side support member 61 rotating together with the shaft 2 and a seal ring 167 tiltably supported by a fixed side support member 64 fixed to a casing 1. In an inner peripheral surface of the seal ring 167, the opposite part to a tip side outer peripheral part of the fixed side support member 64 is provided with an annular projecting stripe 167A for receiving mechanical interference of the tip side outer peripheral part of the fixed side support member 64 with respect to the inner peripheral surface of the seal ring 167 instead of the inner peripheral surface.

摘要： PROBLEM TO BE SOLVED: To provide a liquid pump capable of preventing leak of liquid from a mechanical seal part. SOLUTION: The water pump 1 is provided with a rotating shaft 30, a rotor 20, a housing 10, and a mechanical seal section 50, interposed between the rotating shaft 30 and housing 10, surrounding the rotating shaft 30, and forming a liquid-tight space covering the rotor 20 in the housing 10. The mechanical seal section 50 is provided with a stationary body 53 connected to the housing 10, a rotary body 52 connected to and rotating with the rotor 20 and abutting on the stationary body 53, and a spring 56 enhancing air tightness at the mechanical seal section 50 by pressing the stationary body 53 toward the rotary body 52 in a thrust direction. Distribution of contact force between the stationary body 53 and rotary body 52 is generated by the force applied by cooling water 100 onto the rotor 20. A regulating part 80 is provided for making this distribution uniform. COPYRIGHT: (C)2006,JPO&NCIPI
