Abstract: A telescopic drive shaft in a protective tube of a handheld work apparatus has one end connected to a rotational drive and the other end thereof to a driven tool. The drive shaft includes a rigid shaft segment and a connecting section. The rigid shaft segment has a hollow shaft end portion and an engagement length (E) of the connecting section engages therein. The engagement length (E) and the length of the hollow shaft end portion mutually overlap to form a joining section. The hollow shaft end portion is deformed for connecting the connecting section to the rigid shaft segment. The material of the hollow shaft end portion is compressed over its entire periphery and deformed so that the material of the hollow shaft end portion is radially displaced and is pressed in a rotative manner onto the engagement length (E) to produce a balanced, loadable connection.

Abstract: A system for transmitting power from a drive shaft to a seed meter shaft of a seeder is disclosed. The system comprises a first transmission that connects to one of the drive shaft and the seed meter shaft. The first transmission also connects to a clutch assembly. The clutch assembly connects to a flexible drive shaft assembly, and the flexible drive shaft assembly connects to a second transmission. The second transmission connects to the other of the drive shaft and the seed meter shaft. The clutch assembly is detachable from the first transmission and the flexible drive shaft assembly and the flexible drive shaft assembly is directly connectable to the first transmission.

Abstract: A rotatable drive connection is provided for transmitting torque. The connection includes a first component having an aperture with a plurality of corners. The connection further includes a second component having an end portion with a plurality of edges. The end portion of the second component is smaller than the aperture of the first component. The end portion of the second component is disposed within the aperture of the first component such that at least one of the edges of the end portion is always biased into engagement with at least one of the corners of the aperture throughout a full rotation of the first and second components.

Abstract: A transmission mechanism of a carving grinder and particularly to a transmission mechanism of a carving grinder capable of maintaining concentricity during rotation and enhancing stability to reduce transmission wobbling is provided. The mechanism includes a motor and a transmission tube coupled through a motor transmission member. The motor transmission member has a shaft and a driving member with an axle held by two bearings to improve steadiness during rotation of the shaft and axle. The axle has an integrated embossed key at one end to achieve concentricity. The transmission tube and motor transmission member and driving member are coupled through a square pin and a square hole to further enhance rotation steadiness.

Abstract: A powered apparatus having an elongate pole, a drive at a proximal region of the elongate pole and operable to rotate a first component on the drive, a tool at a distal region of the elongate pole with a second component that is rotatable to operate the tool, and a power transmission assembly for transmitting a drive force generated by rotation of the first component to the second component to thereby operate the tool. The power transmission assembly has a flexible drive link with a flexible length located between the drive and at least one other substantially inflexible drive part that is downstream of the drive link. The flexible length of the flexible drive link is greater than four (4) inches.

Abstract: An apparatus for preventing disengagement of an axially movable and rotatable flexible core of a flexible shaft attachment, which has a driven end and a handpiece end, and the driven end has a ferrule for attachment to a rotary power tool. The rotary power tool has an exteriorly threaded hollow output shaft with a first predetermined interior depth for receiving the base end of tool bits that can be used with the power tool, and the flexible shaft attachment has a drive cap attached to the output shaft, and the drive cap has an aperture sized and shaped for receiving the core in fixed rotating engagement. The apparatus includes a generally cylindrical stop plug having an open end portion and a closed end portion, and a cylindrical chamber extending from said open end portion to said closed end portion. The open end portion has an outward extension adapted to engage the end of the output shaft and be held in place by the attached drive cap, and the chamber is capable of receiving the core therein.

Abstract: A flexible drive transmission comprising a flexible drive shaft assembly having a first end connectable to a drive motor and a second end connectable to a driven implement, a tubular casing surrounding and coaxial with the drive shaft assembly, a lubricant disposed within the casing, and a lubricant-seal for blocking leakage of lubricant from the second drive shaft assembly end. The drive shaft assembly comprises a flexible elongated drive transmitting member, a first drive coupling fixed to the drive transmitting member at a first end, and a second drive coupling fixed to the drive transmitting member at the second end. The casing rotatably supports the drive shaft assembly and comprises a tubular flexible conduit, and end fitting that permanently secures one drive coupling against axial movement relative to the casing.

Abstract: A shaft arrangement includes two shaft ends positioned in end-to-end abutting relation and an outer sleeve surrounding the abutting ends of the two shaft ends. The outer sleeve has through-channels for introducing pressure medium in the interface between the shaft ends and the outer sleeve to create a sleeve expanding effect during mounting and dismounting, and a radial grip acting between the sleeve and the two shaft ends, when the pressure medium has been drained through the through-channels, with the radial grip effecting a radial as well as an axial joining of the shaft ends and the outer sleeve. Each shaft end adjacent its abutting end face is equipped with a grip arrangement that is engaged by a thrust member. The thrust member bridges the abutting end faces and engages the grip arrangement inside the outer sleeve to inhibit the two shaft ends from being axially pulled apart even upon application of a large axial force.

Abstract: A drive element (10) is provided for coupling together rotatable shafts (12) and (14). The shafts (12) and (14) are able to rotate about their respective longitudinal axes (12A) and (14A). Additionally, the shafts (12) and (14) can pivot relative to each other about a pivot point P which is coincident with the geometric center of the drive element (10). Drive element (10) includes a groove (20) for receiving a tongue (16) of shaft (12); and, a tongue (22) which is seated in a groove (18) formed in shaft (14). Surface (26) of the groove (20) and surfaces (34) on opposite sides of the tongue (22) are shaped so that as the axes of rotation (12A) and (14A) of the shafts (12) and (14) are pivoted relative to each other through a predetermined range of angles the respective loci of closest contact between the shafts (12) and (14) and the pivot point P remains constant.

Abstract: All points at which torque is usually applied to subsea equipment, particularly in the search for and production of oil, are centralized at a single panel upon which standard kinds of connecting terminals fitted with sockets are clearly marked and corresponding to torque working points, in order to make access easier by remote operated vehicles.Individual connection between applying points and the sockets on the panel is achieved by means of flexible devices.
