摘要:
A power transmission device that includes a transmission; a transmission case that accommodates the transmission; a counter drive gear to which power from the transmission is transmitted; a brake that holds one of rotary elements of the transmission stationary to the transmission case such that the rotary element cannot rotate; and a support member that includes a cylindrical boss portion rotatably supporting the counter drive gear, a wall portion extended outward in a radial direction of the transmission from one end of the boss portion, and a cylindrical drum portion extended in the same direction as that of the boss portion and in an axial direction of the transmission from the wall portion and functioning as a brake drum of the brake, and that is fixed to the transmission case, wherein the boss portion, the wall portion, and the drum portion are formed integrally.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.
摘要:
A drive system includes a drive housing and one or more drivetrain cartridges. The one or more drivetrain cartridges enables better manufacturability by allowing drivetrain components to be installed together outside the housing and then installed as a unit together into the housing. Serviceability is improved by allowing one or more of the drivetrain cartridges to be removed individually from the housing for maintenance or repair. The housing may include mounting surfaces to securely engage the one or more drivetrain cartridges to the housing to prevent play. The housing may include a bottom or side panel with installation mounts to fasten the drivetrain cartridge or cartridges securely to the bottom or side panel of the housing.

A gearbox supporting device of a wind turbine that has a rotor, a substantially horizontally oriented rotor shaft, a gearbox, and a main frame. The gearbox supporting device includes at least one rolling bearing arranged between a rotor hub and the gearbox and at least two supports on the gearbox. The supports each have at least one central supporting body, at least one frame and a plurality of flat elastomer bodies that are clamped between the frame and the central supporting body. The central supporting body is supported only on one side.

A transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle of the motor vehicle. The transfer case includes a housing, an input shaft allocated to the driving unit, a first driven shaft allocated to the first axle, and a second driven shaft allocated to the second axle and offset parallel to the input shaft. The transfer case further includes an offset drive for transmitting driving torque from the input shaft to the second driven shaft. The offset drive comprises a gear wheel coaxial to the input shaft or to the driven shaft. The gear wheel is rotatably mounted on a section of the housing.

A right-angle drive having dual shaft bearings is provided. The right-angle drive includes a pair of transmission assemblies that each have a shaft. Each shaft is supported by multiple bearings to enhance the load-bearing capabilities of the transmission assemblies.
摘要:
A family of transmission gearing arrangements provides between eight and ten forward speed ratios and a reverse speed ratio. Three planetary gear sets are located on the input axis and a fourth planetary gear set is located on an offset axis. Axis transfer gears convey power between the input axis and the offset axis. One axis transfer gear is supported by a front support while another is supported by a center support. The center support also supports a clutch module and supplies pressurized fluid to engage the clutches in the clutch module.

A power unit having a casing for rotatably supporting a driving force output power shaft and for protecting an oil seal provided between the casing and the driving force output power shaft. A first casing for rotatably supporting input power shafts and a second casing disposed at a position offset in an axial direction from the input power shafts and having an output power shaft supporting portion on which a driving force output power shaft provided in the transmission. The first and second casings are disposed adjacent each other such that the output power shaft supporting portion projects to a side farther than the first casing. A breather chamber is formed between first and second case members which cooperate with each other to configure the second casing disposed above a projection of one end portion of the driving force output power shaft from the output power shaft supporting portion.
摘要:
A slew drive includes a housing, a worm shaft having a worm thread carried within the housing for rotational movement and a torque tube having an outer surface. The torque tube is carried by the housing for rotational movement perpendicularly to the worm shaft and worm thread. A ring gear section having teeth is carried by the torque tube with the teeth engaging the worm threads. An inner raceway is fabricated as an integral part of the torque tube. An outer raceway is fabricated as an integral part of the housing, the outer raceway radially overlying the inner raceway, and bearing elements captured between the inner raceway and the outer raceway.
摘要:
A planetary gear transmission has a gearbox, multiple stages of planetary gears, and an output shaft. Except for the last stage, each planetary gear stage shares a common first internal gear ring. Each stage has a sun gear, a planet carrier, and multiple planet gears. The sun gear of each stage, except for the first stage is integrally formed with or fixed to the planet carrier of an immediately preceding stage. The last stage of the transmission has a second internal gear ring. The planet gears of the last stage mesh with the second internal gear ring. The second internal gear ring includes a support portion, and the output shaft passes through and is rotatably supported by the support portion.
