Abstract

In an axial blower wheel with a number of blades swingably journalled in a hub ring 3, each blade base 1 is connected with a blade shaft 4 by a bayonet engagement between said two elements of which one has a part shaped as a bayonet male part having at least one pair of opposed cam portions 28, 29, and the other a part shaped as a bayonet socket part designed with a bore 7 with grooves 30, 31 matching said cam portions 28, 29. Bayonet male part and bayonet socket part may each be made as part of either blade base or blade shaft. The grooves 30, 31 in the bore 27 of the bayonet socket part are made with play in the axial direction relative to the axial length of the cam portions 28, 29 of the bayonet male part. Two fixing screws 34, 35 are extending through threaded bores 36, 37 in the blade base 1 and have their ends formed as smooth guides 38, 39 for insertion into fit holes 40, 41 in a centring part 42 of the blade shaft 4. Within the guide 38, 39, each fixing screw 34, 35 has a collar 43 for abutment against a spring element placed between the blade base 1 and the side of the centring part 42 facing this. At the mounting of the blade, tightening of the fixing screws 34, 35 is done after establishing the bayonet engagement. Hereby, the blade base 1 with the blade is pressed outwards into frictional engagement between the cam portions 28, 29 of the blade shaft and the grooves 30, 31 in the bore 27 of the blade base 1. <IMAGE>
