A case that houses a chain includes a first cover member fixed to a cylinder block and a cylinder head, and a second cover member arranged on the opposite side of the cylinder block and the cylinder head from the first cover member. In an intermediate part, which is a part of a confronting wall of the first cover member between the first flange and the second flange, a cover-side rib is provided, having a height so that a distal end of the cover-side rib is not in contact with the cylinder block.

An adaptor is used to couple a prime mover to an actuator. The adaptor includes a first portion that attaches to the prime mover and a second portion that attaches to the actuator. The outer surface of the first portion is defined by at least one flat portion connected by at least one arcuate portion. The second portion has a bore configured to accept the first portion, with an inner surface shaped to complement the outer surface of the first portion. A bore through the first portion accepts a drive shaft of the prime mover therethrough where the drive shaft is configured to engage the actuator.

The present disclosure is directed to a gearbox assembly for a wind turbine. The gearbox assembly has a maximal installed width and a maximal transport width. The maximal installed width is greater than the maximal transport width. The gearbox assembly includes at least one torque arm coupled to opposing sides of the gearbox housing. Each of the torque arms includes a proximal end and a distal end. The proximal ends are removably coupled to the exterior surface of the gearbox such that the distance between the distal ends define the maximal installed width. The torque arms are coupled to at least one support element and to a bedplate of the wind turbine.

A suspension assembly for a motorized vehicle includes a rotatable drive-unit driveshaft extending outwardly from an aperture of a drive unit. A first portion of a dropcase is pivotally coupled to the drive unit. A first end portion of a dropcase driveshaft is coupled to the drive-unit driveshaft such that rotation of the drive-unit driveshaft causes a corresponding rotation of the dropcase driveshaft. A second end portion of the dropcase driveshaft extends outwardly from a second portion of the dropcase and is suitable for coupling to a wheel hub. A pivotal-coupling assembly pivotally couples the dropcase to the drive unit. The pivotal-coupling assembly provides a pivot axis between the dropcase and the drive unit along a longitudinal length of the drive-unit driveshaft.
