Estimating the term…
This cam motion machine comprises several cams each defining at least one running track for a follower roller. Each cam is provided with a centring reaming on a drive shaft, while means are provided to apply a tightening force parallel to this drive shaft with a non-circular section. At least one washer-spacer, for which the internal edge is non-circular and designed to enable an axial displacement along the shaft and to fix the washer-spacer and the shaft in rotation, and is arranged around this shaft bearing in contact with at least one of the cams. The washer-spacer may be fixed to the cam by adherence and to the shaft by cooperation of shapes due to complementary projections provided respectively on the shaft and on the washer-spacer.
Cam motion machine for a weaving loom, said machine comprising several cams each defining at least one running track for a follower roller, each cam being provided with a centring reaming on a drive shaft, while means are provided to apply a tightening force parallel to said drive shaft, characterised in that:
Washer-spacer of a cam motion machine for a loom, said washer being flat with a constant thickness and provided with a non-circular internal edge designed to enable axial displacement along a drive shaft of the cams of said machine, and to fix said washer-spacer in rotation with said shaft, this washer also being designed to be pushed into contact with at least one cam of said machine under the effect of a tightening force parallel to said shaft.
Cam for a cam motion machine for a loom, said cam defining at least one running track for a follower roller while being provided with a centring reaming on a drive shaft, characterised in that said cam is provided with a recess that runs along the edge of said reaming and opens up into said reaming, on at least one of its side faces perpendicular to said running track, said recess being designed to hold a washer-spacer arranged around said drive shaft, when said cam is mounted on said shaft.
