A propeller shaft includes: a cylindrical boot member including a protruding portion, and a boot band tightening portion; a shaft member which is inserted into the boot member, and which includes a first diameter portion having an outside diameter greater than an inside diameter of the protruding portion, a groove portion which has an outside diameter smaller than the outside diameter of the first outside diameter portion, and in which the protruding portion is received, and a second outside diameter portion having an outside diameter greater than the outside diameter of the first outside diameter portion; and a boot band tightened on the boot band tightening portion.

The present invention relates to a measuring device with a magnetic field sensor for detecting at least one operating parameter of an agricultural joint shaft for torque transmission between a power take-off shaft of a towing vehicle and a transmission of an agricultural appliance, which includes at least one journal cross, to the opposing journals of which a shaft body is connected, and a protective tube rotatably accommodating the shaft body therein, wherein the magnetic field sensor is adapted to measure a magnetic field emanating from the bare shaft body of the joint shaft.

A universal joint shaft with universal joint shaft protection comprises at least one shaft element for transmitting torque, at least one protective tube element arranged around the shaft element, and an intermediate bearing, by means of which the shaft element is rotatably mounted about an axis of rotation (L) in the protective tube element, wherein the intermediate bearing comprises an outer ring fixed to the protective tube element and an inner ring fixed to the shaft element, which are rotatable relative to each other, and a clamping mechanism by means of which the inner ring is fixed on the shaft element.

A drive shaft (1) includes a telescopic shaft (3) having an outer tubular shaft (9) and an inner tubular shaft (11) inserted slidable into the outer shaft (9). A lubrication system is further provided, including: a lubricant receiving chamber (39) housed in the inner shaft (11); a lubricant distribution block (41) housed in the inner shaft (11); lubricant supply ports (11.9) for supplying lubricant from the lubricant distribution block (41), through a tubular wall of the inner shaft (11), towards a gap between the inner shaft (11) and the outer shaft (9); at least a lubricant transferring duct (47.1; 47.2) from the receiving chamber (39) to the distribution block (41). wherein the supplying ports (11.9) are distributed in at least two positions offset in direction of the axis (A-A) of the telescopic shaft (3).

A guard for a power transmission coupling includes first and second housing members extending longitudinally along corresponding first and second axes and each having first and second longitudinal ends. The first longitudinal end of the first housing member defines an opening configured to receive one of a drive shaft and a driven shaft of the power transmission coupling while the first longitudinal end of the second housing member defines an opening configured to receive the other shaft. The second longitudinal end of the second housing member is configured to be telescoped within the second longitudinal end of the first housing member and the second housing member is movable relative to the first housing member in the direction of the first axis. A plurality of guides are disposed between and couple the first and second housing members and are configured to allow relative movement of the first and second housing members.

A safety guard support for a power take off shaft, the safety guard support: including a bearing; and a retainer ring. The bearing and the retainer ring including corresponding interlocking formations configured to prevent rotation of the bearing relative the retainer ring about a longitudinal axis.

A dual plunging constant velocity (CV) drive shaft is provided for communicating rotational forces from a transaxle to a drive wheel of a vehicle. The dual plunging CV drive shaft comprises a drive shaft that transfers torque from the transaxle to the drive wheel. An inboard plunging CV joint is coupled between the transaxle and the drive shaft, and an outboard plunging CV joint is coupled between the drive shaft and the drive wheel. The inboard and outboard plunging CV joints each comprises an elongate housing that receives a CV joint coupled with the drive shaft. The inboard and outboard plunging CV joints communicate rotational forces from the transaxle to the drive wheel during vertical pivoting of a trailing arm coupled with the outboard plunging CV joint. The elongate housings allow the drive shaft to “float” longitudinally, as needed, during extreme pivoting motion of the suspension.

A protective device for a universal shaft (3) has an attachment element (6), a tubular guard (7) and at least one latching device (24, 25). The attachment element (6) is positioned around a shaft journal (2) projecting from a housing (1). The tubular protective protective guard (7) extends along a longitudinal axis L and is positioned around a universal shaft (3) connected to the shaft journal (2). The at least one latching device (24, 25) attaches the protective guard (7) on the attachment element (6). The protective guard (7) has at least one joining lines (9, 10) extending in the longitudinal direction L. The protective guard (7) can be separated and opened to receive the universal shaft (3).

A protective device for a universal shaft (3) has an attachment element (6), a tubular protective guard (7) and a latching device (24, 25). The attachment (6) is positioned around a shaft journal (2) projecting from a housing (1) and is attached to said housing (1). The tubular protective guard (7) extends along a longitudinal axis L and is positioned around a universal shaft (3) connected to the shaft journal (2). The latching device has at least one latching element (24) and at least one latching projection (25). The latching element (24) is arranged on either the attachment element (6) or the protective guard. The latching projection (25) is arranged on either the protective guard (7) or the attachment element (6). The latching element (24) is displaceable between a latched position and a release position. The latching element (24) is elastically formed and engages, in the latched position, behind the latching projection (25).

The drive shaft (1) comprises end universal joints (5, 7) with accident-preventing end protections (19). Each accident-preventing end protection comprises a lubricant reservoir, delimited radially inwardly by a sleeve (63) of an inner fork (23) of the respective universal joint (5; 7) and radially outwardly by a rigid annular structure of the accident-preventing end protection.
