Patent number: 6506007Abstract: A fastening bolt fastens flanges between a bolt head and a nut attached on the threaded portion of the shaft via spherical washers. The fastening bolt has a cavity formed within the shaft. By application of pressure in the cavity with a hydraulic fluid supplied through a hydraulic pressure port in a plug, the shaft is extended and the fastening bolt becomes unfastened condition. In the unfastened condition, a gap is created between flange and nut, and the nut and the fastening bolt are free to rotate each other, therefore, the nut can be removed easily by hand from the fastening bolt, even the bolt is large in size. The fastening force is adjustable by the width of the gap before releasing hydraulic pressure in the cavity. By releasing hydraulic pressure in the cavity, the fastened condition is obtained. Conversion between fastened condition and unfastened condition can be made quickly and easily.Type: GrantFiled: January 28, 2002Date of Patent: January 14, 2003Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Mitsuharu Kishimoto, Yukihiko Koza, Hiroki Nomoto, Kenichi Yajima

Publication number: 20020114681Abstract: An improved bolt/nut structure capable of preventing from dead locking and loosening and being vibration resistive, wherein, an internal threaded lining and an external threaded sleeve are made from helix springs with the cross section of each ring thereof in the shape of “]” and are used as an external thread and an internal thread for the bolt and the nut respectively to provide the function of dead locking and loosening and of vibration resisting. A plurality of expansion slits are provided on the internal and external peripheries of the helix springs, the springs with the expansion slits are suitable for use on the surface with collapsing of screw threads to suitably expand, and to confine the screw threads respectively. Moreover, a single or a plurality of helix springs are provided to form the internal threaded lining or the external threaded sleeve of one of various pitch gauges, thereby, the bolt structure has the capability of changing for the coarse and fine threads.Type: ApplicationFiled: February 22, 2001Publication date: August 22, 2002Inventor: Shao-Chien Tseng

Patent number: 6368053Abstract: An impeller clearance adjustment system provides for the desired clearance between an impeller and suction housing irrespective of the amount of torque applied to the bolts of the adjustment system. A bearing housing has a plurality of generally evenly spaced apart threaded first openings while a bearing frame has a plurality of threaded second openings registerable with the first openings. A twinsert is threadably received within each of the plurality of second openings. An adjustment bolt, having an opening in its central axis, is threadably inserted into each of the first openings and abuts a face of a twinsert. An attachment bolt is inserted through each adjustment bolt's opening and is threadably received within the respective twinsert. Once the impeller clearance is set, each attachment bolt is tightened thereby maintaining the set impeller clearance.Type: GrantFiled: November 17, 2000Date of Patent: April 9, 2002Inventor: Michael J. Knight, Sr.
