Abstract
A lubricating device for a propeller shaft with two tubular plunging profiles (2, 4) inserted into one another. The lubricating device has two formed parts (16, 21) and a connecting hose between the two. The first formed part (16) is arranged towards the inner end (12) of the inner plunging profile (4). The first formed part has a through-bore (17) which ends in apertures (14, 15) opening towards the region of transition between the plunging profiles (2, 4). The first formed part further includes a connecting sleeve (18) with a lubricating channel (19). The second formed part (21) is arranged in the region of the other end of the inner plunging profile (4). It is secured inside the inner plunging profile (4). The second part has a continuous lubricating channel (23) extending through a connecting sleeve (22). A lubricating nipple (24) is threaded into the other end of the lubricating channel (23). The two formed parts are connected by the hose (27) slid over the connecting sleeves (18, 22). The parts of the two plunging profiles (2, 4) slide on one another and are lubricated by pressing lubricant through the lubricating nipple (24).
