A drive shaft assembly to interconnect a driving component and a driven component has a first shaft and a second shaft operably engaged with the first shaft to enable torque transmission and relative axial sliding motion. A joint component operably interconnects one of the first and second shafts to one of the driving and/or driven components. The joint component is rotatable through a specified range of rotation, or 'free-motion'. The joint component is axially fixed relative to one of the second shaft, driving component and/or the driven component.

Drive shaft coupling

A torque transmission device, for driving or in drives of agricultural implements or self-propelled working machines, has a coupling () with a coupling housing () including a connection plate () and a coupling hub (). Torque transmission elements () are positioned between the two in at least one rotational direction for transmitting a torque between the two. A driving member () defines a longitudinal axis (). The driving member () is provided with distributedly arranged second driving elements () around the circumference of and radially projecting from a driving member portion (). Gaps () are formed in a circumferential direction between the second driving elements (). A support plate () is present on which the driving member () is rotationally supported around the longitudinal axis (). First driving elements (), as distance holders, retain the support plate () at an axial distance to the connection plate () on the coupling housing (). A space () is formed between the driving member () and the connection plate (). The driving member portion () of the driving member () is received in the space (). The first driving elements () engage driving member () in the gaps () in a circumferential direction around the longitudinal axis () with a limited rotational free motion in reference to the connection plate ().

Torque transmission device

A torque limiting coupling has a first coupling hub () with first driving members (), and a second coupling hub () with second driving members (). The hubs () are jointly received in a coupling sleeve () and are rotatable independently of one another. When a set torque is exceeded while the first coupling hub () is driven in one of two driving directions of rotation Nor N, the second coupling hub () is subjected to a force which ensures that, in the driving direction of rotation N, the driving members () of the first coupling hub () are transferred into the disconnected position and that, in the driving direction of rotation N, the second driving members () of the second coupling hub () are transferred into the disconnected position.

Torque limiting coupling

A coupling, especially a torque limiting coupling, has a coupling housing ( ) and an inner coupling member ( ) received therein. The inner coupling member ( ) connects to a drive shaft. Torque transmitting elements ( ), active in the form of locking members, are positioned between the inner coupling member ( ) and the coupling housing ( ). The coupling housing ( ) has a connecting bore portion ( ) which receives a connecting portion ( ) of a connecting element ( ). The outer contour ( ) of the connecting portion ( ) follows the inner contour ( ) of the coupling housing ( ) in the area of the connecting bore portion ( ). The connecting portion ( ) is accommodated with a radial clearance. Thus, radial displacements, circumferential displacements as well as angular displacements are possible between the coupling housing ( ) and the connecting element ( ).

Coupling, especially torque limiting coupling

A drive assembly, especially for agricultural implements with rotatingly driven masses, has a shear pin coupling ( ) with a coupling hub ( ) and a coupling sleeve ( ) rotatable relative to the coupling hub ( ). A ratchet gear ( ) supported on the coupling hub ( ) and rotatable relative to the coupling hub ( ) and the coupling sleeve ( ). All three components ( ) are connected to one another by the head screw ( ) constituting the shear pin. A ratchet (not illustrated) may engage a holding face of the ratchet gear ( ). This results in the head screw ( ) being sheared. As a result, the coupling sleeve ( ) is disconnected from the coupling hub ( ) in respect of drive.

Drive assembly, especially for agricultural implements

A shaft-hub-connection has a shaft with an external face portion seating in a first bore portion ( ) of the hub ( ). A tensioning screw ( ) is provided with a head which is supported on a support disk ( ). The disk is non-movably held in an axial direction on the hub ( ), in the tensioned condition where the threaded shank ( ) sits in the threaded bore ( ) of the shaft ( ). A nut ( ) is between the support disk ( ) and the shaft ( ). The nut ( ) is on the threaded shaft ( ). This nut ( ) is non-movably retained on the shank. When actuating the tensioning screw ( ) in a disconnecting direction the nut ( ) abuts the support disk ( ), so that the hub ( ) and the shaft ( ) move away from each other and become separated.

Shaft-hub-connection

A bearing ring ( ) for supporting a protective device of a rotating driveshaft is adapted to engage an annular groove of a component of the driveshaft, for example a joint yoke. The bearing ring ( ) has a basic ring portion ( ) which connects to a component of the protective device. The bearing ring also includes a bearing ring portion ( ) which engages the annular groove. The bearing ring ( ) is a composite component. The basic ring portion is produced from a different type of plastics than the bearing portion. The bearing portion ( ) is produced by being injection molded around the basic ring portion ( ). The bearing portion ( ) is a PEEK material. Thus, the bearing portion ( ) achieves a long service life while the costs of the bearing remain acceptable.

Bearing ring for supporting a protective device

A protective device for a driveshaft (1), with two universal joints (2, 3) has a protective cone (6) associated with the first universal joint. The protective cone (6) has an extension in the form of a cone portion (14). A sleeve (15) is received in a rotationally fast way in the cone portion (14). The sleeve (15) cooperates with an adapter ring (21). The adapter ring (21) is stationarily secured to an agricultural implement. The sleeve (15) is positioned on the adapter ring (21). The sleeve has inwardly directed splines which engage correspondingly distributed grooves (23) in the outer face of the adapter ring (21) which achieve a rotationally fast connection. The protective device also includes a first protective tube connected to the first protective cone (6). The first protective tube is associated with a second protective tube of the second universal joint in a rotationally fast way. The second tube is firmly connected to the second protective cone by an attaching cap. The attaching cap is secured to the second universal joint so that the entire protective device remains rotation free.

Protective device for a driveshaft

A protective device for telescopic driveshafts used in driving agricultural implements has two protective tubes (8, 9) which are axially inserted into, and overlap, one another. The tubes (8, 9) are adjustable relative to one another along their longitudinal axis (5) and are made of plastics. The outer protective tube (8) includes three circumferentially distributed pairs of ribs ( 13, 14). The ribs (13, 14) are arranged at a distance from one another and a groove (11) is formed between the ribs (13, 14). Guiding webs (15) are provided between pairs of ribs ( 13, 14). The webs (15) project inwardly towards the longitudinal axis (5) from the inner face (12) of the outer protective tube (8). The webs (15) also project inwardly towards the longitudinal axis (5) and serve to center and radially support the tube (9). The outer face of the outer protective tube has a smooth finish. Thus, there are no projections which may possibly injure the operative when unintentionally rotating the protective device.
