A system for adjusting and/or restraining a gearbox of a wind turbine includes a base component fixed to the gearbox and a vertical displacement device configured atop the base component. As such, the vertical displacement device is configured to apply a force to the base component. Accordingly, by lifting the vertical displacement device, a downward vertical force is applied to the base component so as to adjust (i.e. lower) the gearbox.

A link assembly between an engine and a gearbox includes a male link coupled to the engine or the gearbox, a female link coupled to the engine or the gearbox, wherein the female link receives the male link to allow translation of the male link relative to the female link and to form a radial interface, wherein the radial interface dampens translation of the male link relative to the female link, and a pin releasably coupled to the male link and the female link to selectively retain the male link and the female link.

A propulsion system for a tiltrotor aircraft includes an engine supported by the airframe and a fixed gearbox operably coupled to the engine. Inboard and outboard pedestals are supported by the airframe and positioned above the wing. A pylon assembly is rotatably coupled between the inboard and outboard pedestals. The pylon assembly includes a spindle gearbox having an input gear, a mast operably coupled to the input gear and a proprotor assembly operable to rotate with the mast. The spindle gearbox is rotatable about a conversion axis to selectively operate the tiltrotor aircraft between helicopter and airplane modes. A common shaft, rotatable about the conversion axis, is configured to transfer torque from an output gear of the fixed gearbox to the input gear of the spindle gearbox. Each of the inboard and outboard pedestals includes a pillow block housing such as a full or a split pillow block housing.

A vehicle mounted hydraulic pump assembly includes a gearbox that is configured to be connected to a power take-off that is driven by a transmission of a four-wheel drive vehicle. The gearbox includes an input gear and an output gear where a radius of the input gear is the same as a radius of an output gear. A female output connector is associated with the output gear and is configured to be disposed below a forward driveshaft that is associated with the transmission. A hydraulic pump is connected to the gearbox and is configured to be disposed forward of a transfer case that is also associated with the transmission.

A method of mounting a motor to a gearbox includes positioning a coupling along an input shaft of the gearbox from a starting position to a first alignment position. In the starting position, the coupling drivingly engages a greater portion of the gearbox input shaft than in the first alignment position. In the first alignment position, the coupling operatively contacts the motor output shaft. Another step includes rotating the coupling so that the coupling aligns with the motor output shaft. Another step includes axially positioning the coupling at a second alignment position such that the coupling drivingly engages both the motor output and the gearbox input shafts. Another step includes positioning the motor to allow mounting of the motor on the gearbox with the coupling at a third alignment position drivingly engaging a greater portion of the motor output and the gearbox input shafts than in the second alignment position.
