The present invention relates to a method for the assembly of or for preparing to assemble a traction drive module (10) in a drivetrain (2) with the method steps: providing a traction drive module (10) having a transmission housing (18) in which are arranged a first gear wheel (40) rotatably mounted on the transmission housing (18), a second gear wheel (48) arranged at a center-to-center distance (58) to the first gear wheel (40), and a traction means (46) via which the first and second gear wheel (40, 48) are in rotary driving connection with one another; attaching an assembly aid (16) acting between the second gear wheel (48) and the transmission housing (18) and detachable from the traction drive module (10); and changing the center-to-center distance (58) by moving the second gear wheel (48) relative to the transmission housing (18) while adjusting a predetermined tension of the traction means (46) by means of the detachable assembly aid (16). In addition, the present invention relates to a traction drive module (10).

A transmission for an agricultural or heavy load vehicle is provided, and includes a central drive shaft, at least one planetary gearset comprising a planet carrier, at least one output drive element, and one brake device. The drive shaft is connected to the output drive element via the planetary gearset. The brake device is located between the planet carrier and the output drive element in the form of a ring gear, such that the output drive element can be coupled to the planet carrier via the brake device.

An apparatus and a method of retaining a bearing assembly having a bore to a shaft received within the bore, the method comprising physically limiting the axial movement of the bearing assembly on the shaft by a retainer mounted to an end of the shaft and having a portion extending radially beyond the shaft and into an axial path of the bearing assembly.

A profiled wheel assembly for coupling to a shaft includes a profiled wheel having a first guide slot extending radially outwardly from a central aperture of the profiled wheel and a first assembly slot spaced apart from and parallel to the first guide slot. A retainer is supported on the profiled wheel for movement between a lock position wherein the retainer axially locks the profiled wheel relative to the shaft and a release position wherein the retainer axially unlocks the profiled wheel relative to the shaft.

A floating spacer assembly for a gear mounted on a shaft, such as a planet gear mounted to a planet carrier, is disclosed. The gear may be mounted on the shaft with a pair of roller bearings with inner races and bearing rollers, and a gear bore having a gear groove defined therein functioning as the outer races of the roller bearings. The floating spacer assembly may include an annular spacer ring having one or more sector slots circumferentially spaced around the spacer ring, and a spacer sector disposed within each of the sector slots and extending radially outward from the spacer ring and into the gear groove when the floating spacer assembly is installed between the roller bearings. The spacer sectors may engage surfaces of the gear groove and the spacer ring may engage the bearing rollers to limit axial movement of the gear relative to the shaft.

A pulley device for a tensioner roller or winding roller of a transmission element, providing a pulley, and a bearing. The bearing includes a rotating outer ring mounted to the pulley, a fixed inner ring, and at least one row of rolling elements arranged between the rings. The inner ring of the bearing has at least one end portion protruding axially with respect to the outer ring. The pulley is provided with at least one pulley element that is C-shaped in axial section. One of the at least one pulley elements is provided with a lateral portion extending substantially radially to pass into the immediate vicinity of an outer surface of the axially protruding end portion of the inner ring.

A transmission system has a housing including a wall and a gear support extending from the wall. The gear support has an outer surface and an inner surface defining a passage. The outer surface includes a seal receiving portion and a seal support axially spaced from the seal receiving portion. A seal is positioned about the gear support at the seal receiving portion. A sleeve is arranged on the outer surface of the gear support between the wall and the seal and a pump drive gear is mounted on the gear support and is supported by the sleeve. The pump drive gear includes an outer toothed surface, an inner surface, and a bushing arranged on the inner surface, the bushing extending about the sleeve.

A transmission includes a transmission main housing, an intermediate plate secured to the transmission main housing; and a rear housing attached to the intermediate plate. An input shaft is connected to an extension shaft including a plurality of splitter gears selectively couple-able to the extension shaft. A main shaft is rotatably supported on the extension shaft and includes a plurality of main box gears selectively couple-able to the main shaft. A range shaft is drivingly connected to the main shaft and provides input to a planetary gear assembly, the range shaft being supported by a first bearing disposed within the intermediate plate and further including a bore disposed within a forward end. The extension shaft is supported at a first end by a bearing assembly within a partition wall and a second end is supported by a bearing assembly disposed within the bore in the range shaft.

A rear mount power take-off for a transmission includes a housing assembly configured to be mounted in an opening in the transmission. A power take-off shaft includes an externally splined end extending into an opening in the housing assembly and is configured to be driven by a component of the transmission. A guide sleeve is received in the housing assembly and includes an exterior shoulder opposing an interior retaining shoulder of the housing assembly, the guide sleeve further including an interior shoulder. A spring biases the guide sleeve against the interior retaining shoulder of the housing assembly. A coupler sleeve is secured to an interior of the guide sleeve and includes a first internal spline for selective engagement with the externally splined end of the power take-off input shaft and a second internal spline configured to engage a power take-off device.

Belt-driven systems, such as a front-end accessory drive for an internal-combustion engine, often include one or more idler pulleys. It is typical for these idler pulleys to be retained by a bolt or bolt and washer. To obviate the bolt and washer, a fastener-less system has a shaft with a circumferential groove and a bearing with an inner race that has a circumferential ridge. An idler pulley is mounted on the bearing. The ridge engages with the groove of the shaft to retain the idler pulley/bearing on the shaft. Additionally, either a key inserted into keyways or stakes are used to avoid relative rotation of the inner race of the bearing with respect to the shaft.
