In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

A low-back-clearance robot speed reducer includes a wheel holder (16), a pin gear shell (1), a first cycloidal wheel (6), a roller pin (8), a second cycloidal wheel (11), a gland (2), an elastic member (9), a first cross-shaped slider (5), a second cross-shaped slider (13) and a crankshaft (10). The first cycloidal wheel (6) and the second cycloidal wheel (11) are in a phase relation of 180 degrees and have a multi-point engagement transmission relationship with the pin gear shell (1) and the roller pin (8). The first cross-shaped slider (5) and the second cross-shaped slider (13) form a double cross-shaped slider structure, in which the groove profile of the sliders is of a trapezoidal groove structure. A clearance is automatically axially compensated by the elastic member (9). The center of rotation of the crankshaft (10) is coaxial with the wheel holder (16) and the gland (2).

A coupling e.g. for an actuator, includes a housing which is preferably in the form of a ring mounted around the end of an outer rod of the actuator and which can be mounted to a component e.g. a cowl being deployed. Within the housing of the coupling is provided an eccentric bearing mount and bearing arrangement mounted eccentrically to the housing so as to permit some eccentric movement.

The present invention relates to an actuation device for a compressor inlet adjustment mechanism. The actuation device comprises a housing part and a lever assembly. The lever assembly comprises a bearing section, an input section and an output section. The output section is configured to be coupled to an adjustment ring of the adjustment mechanism on a first side of the housing part. The input section can be coupled to an actuator rod on a second side of the housing part. The lever assembly is rotatably mounted in the housing part via the bearing section on the compressor inlet side here.

An assembly has a radial ball bearing including a bearing inner ring, and a rotatable shaft with a shaft end region with a bearing seat. The bearing seat has a shoulder on one side, on which the bearing inner ring of the radial ball bearing is seated for supporting the shaft. The bearing seat is shortened in the longitudinal direction relative to the radial ball bearing, and extends toward a height of the radial ball bearing. The bearing seat terminates at a distance (L) from an orthogonal projection from the proximalmost points of a distalmost row of balls onto the bearing seat surface such that L=k*D, wherein k is in a range between 0.7 and 0.5.

A bearing for holding a rotary conversion tool (10, 11) that includes two end rolling bearing devices (26, 28), at least one intermediate rolling bearing device (27) interposed between the end rolling bearing devices (26, 28), the end and intermediate rolling bearing devices (26, 27, 28) being intended to engage with an end (10a, 10b, 11a, 11b) of the rotary tool (10, 11), and at least one mechanical actuator (32, 33) configured to exert a radial preload force (Fo, Fo′) at the intermediate rolling bearing device (27).
