An engine reduction gear system includes at least two self-contained, independent engine reduction gearboxes, each capable of connecting to an aircraft engine. Each of the engine reduction gearboxes provides redundant, reduced speed to a main rotor gearbox via a shaft.

A non-pressurized accessory gearbox for an aircraft includes: a housing, one or more gears disposed within the housing, an input rotating member to receive input from a main rotor gearbox via a shaft connected to the one or more gears, and one or more output rotating members in communication with the one or more gears. The gearbox is configured to utilize splash lubrication for moving a lubrication fluid within the housing.

A gear box assembly for a twin rotor combine is provided. The gear box assembly includes a two speed gear box having a casing, an input shaft, an output shaft, and a two speed gear assembly housed within the casing and operatively connected between the input shaft and the output shaft. The gear box assembly also includes a splitter gear box operatively connected to the output shaft. The splitter gear box includes a housing, and a splitter gear assembly housed within the housing and configured to split a torque provided by the output shaft between a first output shaft and a second output shaft extending from the housing in a direction opposite a direction the output shaft extends from the two speed gear box. The two speed gear box is pivotable relative to the splitter gear box housing.

A power transmission device for a work vehicle includes a boss section, a spline shaft, a rotational force transmission section, and a housing. The boss section includes a spline groove on an internal circumferential surface thereof. The spline shaft fits to the spline groove. The rotational force transmission section is coupled to the boss section or the spline shaft. The housing includes an oil sump section retaining lubricating oil. The oil sump section is in communication with a fitting section at which the spline shaft and the spline groove are fitted to each other, an oil inlet path arranged to introduce the lubricating oil into the oil sump section, and an oil drain path arranged to drain lubricating oil retained in the oil sump section, the oil drain path being positioned higher than a lower end of the spline groove.

A motor-gearbox assembly includes a housing, a motor, and a gearbox. The housing includes a first alignment mechanism and a second alignment mechanism. The first alignment mechanism is at a first end of the housing and the second alignment mechanism is at a second end of the housing. The motor is mechanically positioned within the housing in accordance with the first alignment mechanism. The gearbox is mechanically positioned within the housing in accordance with the second alignment mechanisms to mechanically couple to the motor.

A transmission includes a main housing having a rear wall and at least one sidewall extending from the rear wall. The rear wall has an outer side and has an inner side that cooperates with the at least one sidewall to define an interior. A planetary gearset is disposed within the interior. An output shaft is coupled to the gearset and extends through a hole defined in the rear wall. An extension housing is connected to a rear portion of the main housing such that the outer side and the extension housing cooperate to define a torque-sensor cavity. The output shaft extends through the cavity. A torque sensor is disposed within the cavity adjacent to the output shaft and has an electrical connector disposed in a wall of the extension housing.

A motor-gearbox assembly includes a housing, a motor, and a gearbox. The housing includes a first alignment mechanism and a second alignment mechanism. The first alignment mechanism is at a first end of the housing and the second alignment mechanism is at a second end of the housing. The motor is mechanically positioned within the housing in accordance with the first alignment mechanism. The gearbox is mechanically positioned within the housing in accordance with the second alignment mechanisms to mechanically couple to the motor.

Disclosed herein is an assembly structure of a dust cap being coupled to an assembly part of a rack housing which is open such that a steering shaft is inserted therethrough, wherein the dust cap includes a body provided in a hollow tube shape through which the steering shaft passes, a first coupling portion bent to extend outward from the body and press-fitted onto an outer circumferential surface of the assembly part, and a second coupling portion provided to be spaced a certain interval from the first coupling portion and inserted into the assembly part, and the second coupling portion is provided such that, when assembled to the assembly part, a gap is formed between the second coupling portion and an inner surface of the assembly part.

Various embodiments of the teachings herein include a gearbox adapter. For example, some embodiments include an adapter body with an internal cavity, a first end having a gearbox connection structure connecting the adapter body to a gearbox body, a first shaft hole in an end face of the first end providing communication between the internal cavity and an outside of the adapter body, and a second end having an opening in communication with the internal cavity; a transmission shaft configured to extend from the outside into the internal cavity via the opening and then out of the adapter body through the first shaft hole; an opening cover with a second shaft hole, the opening cover fitted at the second end to block the opening but allow the transmission shaft to pass out of the internal cavity through the second shaft hole; and a rotating bearing arranged in the internal cavity and fitted to the transmission shaft to support the transmission shaft.
