ABSTRACT:
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.
