A driving shaft (3) includes an inner tube (1) and an outer tube (2) having a modified cross-section. These tubes (1, 2) are axially movable but not rotatable relative to each other for transmitting torque therebetween. The driving shaft (3) comprises a partition unit having a pair of partition walls (8a, 8b; 16) hermetically sealing at least part of the inside of the inner tube to define a grease reserving space (8A) in the inner tube on the side of its distal end. The partition wall (8a, 16) on the side of its proximal end is provided with a hose mounting portion (8c; 23) having an oil hole (9). The driving shaft (3) further comprises an oiling port unit (10; 20) provided on a fitting yoke (7) on the side of the proximal end of the inner tube and an oiling conduit unit (11; 24, 25) for connecting the oiling port unit (10; 20) and the hose mounting portion (8c; 23) of the partition unit. The driving shaft further comprises a distribution passage unit (13, 14; 14) for distributing grease from the grease reserving space (8A) to the sliding surfaces of the tubes (1, 2) participating in torque transmission. With this construction, the grease is surely supplied to the portions (12) participating in torque transmission of the driving shaft (3) without requiring frequent grease supply. Moreover, there is no risk of the oiling hose from being unintentionally removed from the fixed position.

Eine Schutzabdeckung für Zapfwellen (10) mit einem U-förmig ausgebildeten Gehäuseteil (22), welches in einer Ausgangslage die Zapfwelle (10) von oben und von beiden Seiten her abdeckt, wird so ausgebildet, daß das Gehäuseteil (22) zwischen zwei Wangen (12, 14) um eine Achse (34) schwenkbar gelagert ist. Das Gehäuseteil (22) läßt sich aus einer Ausgangslage herunterklappen, so daß der Basisschenkel (24) aus einer waagerechten Lage in eine senkrechte Lage übergeht und die Stirnseite der Zapfwelle (10) abdeckt. Das Gehäuseteil (22) enthält ferner ein zwischen den freien Schenkeln (26, 28) angeordnetes Abdeckteil (36), welches bei heruntergeklapptem Gehäuseteil (22) die Zapfwelle von oben her abdeckt.

摘要:
A cardan shaft for a tool which is connected to a motor and which is provided with a system for checking the conditions of use thereof. The cardan shaft comprises a rotatable portion which comprises a rotatable shaft, which may be in the form of a telescope-like member, with one or two end cardan joints. One or more sensor members are mounted on the cardan shaft in order to transmit signals to a data acquisition and data-processing electronic control unit (ECU) which is mounted on a fixed protection of the cardan shaft itself. The sensor members are provided to measure data selected from the group comprising: rotation speed of the rotatable shaft of the cardan shaft, number of rotations of the rotatable shaft, vibrations of the cardan shaft, temperature of at least one cardan joint and, when the rotatable shaft (26) is a telescope-like member, extension of such telescope-like member. The system for checking the conditions of use of the cardan shaft comprises a remote node which is connected to the ECU which is mounted on the fixed protection in a wired manner or wirelessly. The remote node is provided to acquire, store and process the data sent to the ECU by the one or more sensor members mounted on-board the cardan shaft.
