Abstract: A compressor has a cylindrical casing unit having at least one open end. A compression element includes a circular cylinder held in the casing unit, a cylindrical rotating body having at least one spiral groove on its outer periphery and eccentrically arranged in the cylinder, and a spiral blade wrapped on the rotating body and fitted in the spiral groove in a manenr to be freely displaceable relative to the spiral groove. The cylinder and rotating body are journaled in a bearing means. A frame includes a cylindrical section intimately inserted into an open end of the casing unit and a disc section blocking the cylindrical section and provided orthogonal to an axis of the cylindrical section, the frame blocking the open end of the casing unit and supporting the bearing means.

Abstract: A bearing device for miniature motors having a cylindrically-shaped bearing support formed by pressing an end face of a metallic motor case, and a bearing press-fitted into the bearing support to rotatably support a motor shaft, characterized in that a pressed groove is formed on the outer circumferential surface of the bearing support by pressing the outer circumferential surface is disclosed. A method of making a bearing device for miniature motor in which the clearance between the bearing and the motor shaft is set by pressing the outer circumferential surface of the bearing support using a pressing jig in a state where the motor shaft is inserted into the bearing is disclosed.

Abstract: The axial mounting with skewing compensation for a turbomachine has a fastening flange (1) and a bearing housing (2) which is in one piece with the latter and which is subdivided into a middle housing part (9) and an outer housing part (10) by means of at least one pair of slots (4,7) in two respective planes. The slots (4,7) are widened in a lobe-like manner at their ends, and these ends respectively limit at least one pair of webs (5,8) located diametrically opposite one another in the said planes. These webs (5,8) perform the function of rigid joints for damping angular deflections of the shaft which are caused by operating loads. The webs (5,8) of the two planes are offset relative to one another by 90.degree., generally by the amount of half their circumferential division.

Abstract: A rotary kiln having a material processing drum rotatably supported by a shaft. The shaft is rotatably supported by a bearing structure having a radial bearing and a thrust bearing. A radial bearing aligner and a thrust bearing aligner are provided for, respectively, aligning the radial bearing and the thrust bearing with the shaft of the drum if the shaft moves relative to the radial bearing and the thrust bearing.

Abstract: A bearing assembly for a shaft comprises a body having a cylindrical bore open at one end, a mount bracket extending from the one end and an annular stop flange at the other end of the bore. An apertured bearing of a hardened plastic material is enclosed within the body and at one end has an annular stop shoulder bearing against the stop flange and defining a cylindrical extension of reduced diameter extending outwardly of the body adapted to journal a shaft. In a modification, an annular groove in the cylindrical extension outwardly of the stop flange receives a snap ring to restrain the bearing against endwise movements relative to the body.

Abstract: A bearing unit of this invention includes, instead of a conventionally used bracket, a housing formed with an external thread and a bush press fitted in an inner bore of the housing.

Abstract: A bearing ring for a drive assembly including a protective funnel and a wide angle joint, wherein the bearing ring consists of an outer supporting ring and an inner sliding ring defining an annular space therebetween with flexible webs extending between the supporting ring and the sliding ring and with supporting cams extending radially into the annular space being provided on the supporting ring of a sliding ring. Radial slots with three points of intersection positioned on a joint center line are provided in two places on the sliding ring and in one place on the supporting ring.

Abstract: An end shield for an electric motor or the like includes a generally disk shaped planar portion having a cylindrical bearing socket therein for mounting a cylindrical bearing. The socket has a cylindrical side wall and an end wall, and is formed from ears and tabs from the material of the disk such that the ears are bent out of the plane of the disk to extend at right angles to the planar portion. The ears define the cylindrical side wall of the socket. The tabs extend generally radially inwardly and define the end wall of the socket. A cylindrical bearing within the socket is retained radially and in axial alignment by the cylindrical side wall of the socket, and is restrained in an axial direction by the end wall of the socket. A spring may be mounted within the socket to resiliently preload the bearings of the motor in the axial direction.

Abstract: A fiber reinforced plastic leaf spring including a curved central section and a pair of end sections, each having a bushing to receive a connecting member. The spring is formed from a plurality of longitudinally extending substantially continuous strands of fibrous material impregnated with a cured thermosetting resin which are wound in a loop configuration around the bushings. The windings consist of a pair of generally parallel runs which extend between the bushings and are disposed in contiguous relation and the resin is cured to formed an integral structure. Each bushing includes a tubular section and at least one circumferentially extending rib that extends outwardly from the tubular section and is encapsulated in the fibrous windings. The ribs act to prevent delamination of the two runs along the neutral axis of the spring when the spring is subjected to load in service.

Abstract: To mount rotatably supporting members such as a rotary shaft to an arm body of an industrial robot arm, the former and the latter are solidly secured to each other by fastening members such as rivets after a bonding agent is applied to spaces formed between the arm body and the rotatably supporting members, whereby necessity for the stage of assembling work by the welding is eliminated, shearing forces are supported by the bonding agent and tensile forces are supported by the fastening members, so that the robot arm being high in precision and mechanical strength can be obtained.

Abstract: A rotary kiln construction of the type where a cylindrical kiln is supported for rotation on an annular bearing ring wherein the ring has an inner circumference larger than the outer circumference of the kiln cylinder and a plurality of spacing plates are arranged around the circumference of the cylinder to support the bearing ring concentrically with the cylinder, supporting assemblies for the spacing plates including a support element welded on the cylinder with abutment strips preventing axial displacement of the bearing ring and angle lugs preventing axial displacement of the spacing plates with the support assemblies located axially opposite each other so as to hold the plates between them and permit withdrawal of the plates from either axial direction.

Abstract: An inboard outboard drive having a structural part which passes through an opening in the hull of a boat. A mounting shield for supporting the structural part is at its inner portion provided with symmetrical receiver grooves into which the support flanges on the structural part may be selectively inserted in either one of two reversed positions and has in an outer portion an asymmetrically located flange for securing to the hull. The shield may according to need be put on the inner or outer side of the hull, depending on which of them is more even than the other.

Abstract: A stiff bearing support for the guide bearing of a drive shaft of a hydro-turbine machine which effectively isolates the radial movement of a grounded head cover from that of the bearing surface while it solidly transfers the lateral bearing reaction load to the grounded head cover.
