摘要： PURPOSE:To provide a dynamic pressure bearing unit that can secure a dynamic pressure bearing body to a housing firmly by means of an elastic body even if a groove and a projection are not formed in this housing. CONSTITUTION:An outer diameter D1 of an axial intermediate part 31 on a peripheral surface of a cylindrical dynamic pressure bearing body to be attached to a housing 2 via a circular tube-form elastic b:4 1 is formed into being smaller than an outer diameter D2 of each of both axial ends 33 and 34. Likewise, in this elastic body 1, an inner diameter D3 is formed smaller than the maximum outer diameter D2 of the dynamic pressure bearing body. Accordingly, if this dynamic pressure bearing body is inserted into the elastic body 1, both these ends 33 and 34 in the axial direction of this bearing body bite into an inner circumferential surface of the elastic body 1.

摘要： PROBLEM TO BE SOLVED: To provide an electric pump, comprising a smaller number of parts, and achieving compactness and low cost. SOLUTION: At the part of a through hole 11a in a partition member (housing base 11) parting a pump part 3 and a motor part from each other, a sleeve 5 is disposed through an O-ring 6, and the sleeve 5 is pressed to a large diameter part 4a formed in a main shaft 4 by an axial direction pressure means (washer 7). In this constitution, the sleeve 5 is a sliding bearing to support rotation of the main shaft 4, and it also composes a mechanical seal to prevent penetration of working fluid on the side of the pump part 3 into the side of the motor part 2. Compared to conventional devices in which a bearing and a seal member are separately disposed at different positions in an axial direction, the number of parts is reduced, and compactness and light weight are achieved.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of applying a finishing process to the inner peripheral surface of a resin bearing sleeve while maintaining its roundness.
SOLUTION: The bearing sleeve 1 is formed by injection-molding a resin, fitted into a cylindrical holder 2 having an opening diameter slightly larger than the outer diameter of the sleeve 1, and the finishing process (cutting process) is applied to the inner peripheral surface of the sleeve 1 while rotating the holder 2 in the held state of the holder 2 by holding means (chuck claws 3a, 3b, 3c) spaced in three or more parts in the circumferential direction. By this holding method, the centering and fixing thereof can be performed without causing partial deformation in the inner diameter of the sleeve 1. As a result, this bearing sleeve 1 less deforms also after it is removed after processing, and the errors of the inner diameter dimension and the roundness of the bearing sleeve can be minimized.

摘要： PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing device causing less abrasive powder and having a long service life while using a low cost resin bearing sleeve.
SOLUTION: A large number of projected parts 1b reducing the contact area thereof with a shaft member are formed on the inner peripheral surface 1a of the resin bearing sleeve 1 excluding a dynamic pressure groove 1v part to facilitate the sliding thereof on the surface thereof. Accordingly, even if the shaft member is brought into contact with the bearing sleeve 1 when the device is started/stopped, abrasive powder can be prevented from being produced. Thus, since troubles resulting from the abrasive powder can be prevented, the service life of the device can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a compact axial-flow pump capable of operating with a high speed revolution in which flow efficiency is high.
SOLUTION: In the axial-flow pump, support members 2, 2 including a hole 2b for supporting a shaft equipped with an impeller 1a are arranged at an inner circumference of a housing 10 with spacing in a longitudinal direction. A rotor 11a and stator 11b of a motor 11 are arranged between the support members 2, 2. Dynamical pressure generating grooves (dynamical pressure grooves) 2v, 2v are each formed on an inner circumferential surface of the support members 2 for supporting rotation of the shaft 1. Consequently, the dynamical pressure is generated in a fluid that has obtained entrance into a gap between the shaft 1 and the hole 2b the support member 2 to thereby enable the shaft 1 to be supported in a contact-free manner. As a result, the pump can be operated at an appropriate revolution speed in which high flow efficiency is obtained.
