Abstract: One embodiment includes a device for solar tracker systems. The device includes a first purlin including a first mating surface configured for frictional attachment to a first side of a torque tube. The first purlin further including a first linear shaped top surface configured for mounting a first solar module. A second purlin includes a second mating surface configured for frictional attachment to a second side of the torque tube. The second purlin further including a second linear shaped top surface configured for mounting a second solar module. The first purlin and the second purlin connect to one another with a fastening clamp that is configured for holding the first purlin and the second purlin against the torque tube.

Abstract: A crankshaft bearing support structure includes a cylinder block having a first holding portion; a first plain bearing held by the first holding portion of the cylinder block; a crank cap fastened to the cylinder block, the crank cap having a second holding portion; a second plain bearing held by the second holding portion of the crank cap; and a crankshaft having an axis of rotation, the crankshaft being rotatably held by the first plain bearing and the second plain bearing and configured to receive an explosive load from a piston via a connecting rod. The crankshaft flexes, when subjected to the explosive load, in a direction of the explosive load. The crank cap in provided with a mechanism which causes the second holding portion to flex in a manner that a bearing holding surface of the second holding portion follows flexure of the crankshaft subjected to the explosive load.

Abstract: A tie rod support apparatus for a large pressure vessel system. The tie rod support apparatus comprises a tie bar, an upper bearing unit, a bottom bearing unit and a tie rod support base. The upper bearing unit is coupled to a pipe section or other component in the large pressure vessel system and includes a bearing to provide a pivotally moveable connection point. The bottom bearing unit is coupled to the other end of the tie rod and configured with the tie rod support base. The tie rod support base is connected or attached to a support surface (e.g. a concrete slab or block) that is independent from the large pressure vessel system. The bottom bearing unit may include a bearing to provide another pivotally moveable connection point. According to an embodiment, the tie rod support includes a length adjustment mechanism configured to allow adjustment of the length or span of the tie bar.

Abstract: The invention relates to a bearing arrangement (1), in particular for bearing the carrying shaft (30) of a parabolic trough collector (26), having a disc- or ring-shaped component (3), at least one support roller (5), which radially fixes the component (3) and on which the component (3) rolls on the circumferential side during rotation about a rotation axis (2), and a support structure (6), on which the support roller (5) is mounted by a radial sliding bearing (8). According to the invention, the lateral surface (12) of the support roller (5) which receives the component (3) has a convex curve in the axial direction. The invention further relates to parabolic trough collector (26) mounted on a plurality of such bearing arrangements (1).

Abstract: An solar tracker bearing comprising a pair of stationary outer bearing races attached on either side of a bearing support element and a rotatable inner bearing race held by the pair of outer bearing races, the rotatable inner bearing race having an beam slot for seating a torque tube beam therein.

Abstract: In a sheet feeder of the present invention, a groove-shaped concave provided on an inner surface of a bearing extends therethrough in a direction where a rotational shaft of a feed roller extends. A surface of the rotational shaft of the feed roller is supported on a pair of outer edges of the groove-shaped concave formed on the inner surface of the bearing. A bottom of the groove-shaped concave is substantially circular-arc and concentric with the inner surface of the bearing other than the groove-shaped concave. The bottom of the groove-shaped concave is formed at such a depth that the surface of the rotational shaft of the feed roller does not contact the bottom while the rotational shaft of the feed roller is supported on the outer edges of the groove-shaped concave.

Abstract: A hangar bearing is designed to be employed in a drying oven, generally known as a "tunnel" type, which is used to dry plywood, veneer board, fiber, or gypsum board. The hanger bearing main body support is made from a pair of identical stamped forms or fabricated plates which include various matched bores to facilitate both mounting and mutual securement. Each of the main body plates includes a depression that conforms to provide a bearing insert support cavity when the plates are fitted together. The bearing insert support cavity may or may not include anti-rotational flanges and/or longitudinal travel stops to hold the semi-cylindrical bearing insert element in place. A steel retaining loop or strap is provided to overarch the bearing element, once it is in place, the loop or strap being preferably provided with a hinge and a releasable retaining clip.

Abstract: A bearing setup is provided for the supporting disks of an open-end spinning machine, the supporting disks being supportively fixed on the ends of a shaft extending through a bearing sleeve of a supporting disk bearing. The bearing setup includes a fastening system configured with the bearing sleeve so that the supporting disk bearing can be readily and easily removed from the pillow block of the spinning machine without disassembly of the pillow block from the machine frame. The fastening system may include a threaded bore defined in the axial sleeve for engagement with a threaded screw member extending through the pillow block.

Abstract: A bearing assembly is disclosed for supporting the downstream end of a shaft for a position indicating system for a turbofan thrust reverser. The bearing assembly has a pair of support arms supporting a bushing which is attached to the downstream end of the shaft. The arms are oriented in a plane substantially transverse to the longitudinal axis of the shaft and are clamped to a mounting bracket by spring biased mounting plates. Belleville springs are utilized to provide the biasing force and may be adjusted to compensate for wear of the system.

Abstract: A bearing support arrangement for electrical machines is made double-walled and box-like and has, between the two walls, reinforcements and supports for the bearings, the bearing support arrangement extending approximately up to the axial center plane of the bearings. The bearing support arrangement can be made in one part or in several parts, that is to say it can, at least on one side of the machine, be subdivided horizontally into two supporting bodies, or the lower supporting body and the upper supporting body, respectively, can likewise be subdivided in a vertical direction.
