PCT No. PCT/SE90/00360 Sec. 371 Date Nov. 19, 1991 Sec. 102(e) Date Nov. 19, 1991 PCT Filed May 29, 1990 PCT Pub. No. WO90/15262 PCT Pub. Date Dec. 13, 1990.An arrangement for locking a shaft or an axle to a machine member. The shaft has a cylindrical part which is intended to carry a bearing. The arrangement includes two expander sleeves which have a control internal shape and each of which is intended to be mounted on a respective end of the shaft of similar conical shape. The expander sleeves function as annular wedges with the apex of the wedge facing towards the cylindrical part of the shaft or axle and when tightening a nut are caused to expand against the machine member and lock the shaft. The shaft comprises an outer sleeve which faces the conically shaped end-parts, and a pin which is arranged coaxially with and within the sleeve and one end of which has an outwardly curved, mushroom-headed end-part whose radially inward surface is intended to abut an adjacent second expander sleeve, and the other end of which pin carries the nut with which the first and second expander sleeves are caused to expand into clamping contact with the machine member when tightening the nut.
