Problems solved by technology

[0003] This attachment by means of adhesion is sometimes not sufficient to securely secure the cam relative to the drive shaft
As far as the performance required of modern camming machines is concerned, their rotational speeds are gradually increased to the point where the torque exerted on the cam by the driven roller can bias the angle of the cam on that axis, which causes the camming machine to become out of tune and Reduced production quality of textiles

Embodiment Construction

[0038] figure 1 The weaving machine M shown comprises a plurality of heald frames, only one of which is shown at 1 in the figure. The different heald frames of the loom M are indicated by the double arrow F 1 The vertical vibratory motion shown is driven and controlled by a cam machine 10, wherein the output rod 11 is in contact with the connecting rod 12, which is connected with the crank rod 13 - which are connected to each other and through the connecting rod 14 connected to the heald frame.

[0039] The number of rods 11 provided is the same as the number of heald frames 1 and they are mounted about the longitudinal axis X of a common shaft 15 supported by the frame 16 of the camming machine 10 15 Free pivoting, as double arrow F 2 shown. The camming machine 10 also comprises a plurality of complementary cams 20 each defining two tracks 20A and 20B on which rollers 21A and 21B are carried in pairs supported by the rod 11 .

[0040] The cams 20 are mounted on a common ...

Abstract

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.

Description

technical field [0001] The present invention relates to a cam motion machine. The invention also relates to a washer-spacer and a cam for the cam-moving machine, a loom in which the cam-moving machine is installed, and a method of assembling the cam-moving machine. Background technique [0002] In the field of looms, it is known that cam machines comprise a series of oscillating rods, one for each heddle frame to be mounted on the loom. Each oscillating lever is designed to be coupled to one of the heald frames and is equipped with two rollers that cooperate with two tracks of a complementary cam controlled by a The common shaft of the kinematic machine is driven in rotation. The cams must be mounted on a drive shaft in such a way that, after having been adjusted to a specific angle with respect to each other according to the function of the desired camming machine, the cams will withstand the axial force exerted by a suitable tightening device. is operatively rotationall...
