摘要:
The present disclosure relates to a system that uses linear actuators to generate a torque on a shaft. In an example implementation, a system may include a shaft and an attached cam. The cam includes an involute portion. The system also includes a first linear actuator and a second linear actuator configured to move along a first axis and a second axis, respectively. The linear actuators are configured to detachably couple to the cam based on at least a reference angle of the shaft. That is, as the shaft rotates about its rotational axis at the reference angle, the first and the second linear actuators may couple to, and decouple from, various portions of the cam. As the linear actuators couple to, and decouple from, the various portions of the cam, different rotational torques and/or different ranges of such torques may be imparted onto the shaft.

A cam apparatus for transforming a linear motion into a rotational motion. The cam apparatus (1) within the start region or upon stoppage of a driving cylinder (4) serves as a drive member. A rotatable turret (2) serving as a follower member with follower rollers (22) is caused to confront a flat portion (10) of a slider (8). The shape of the cams or lobes improves the starting phase.

Selective actuation device (1) comprising and actuator (5) acting upon an actuation lever (7) that has at least one thrusters element (7b) for the actuation of a first operating group (12, 13) and a cam element (6) mobile between an activation position in which it acts upon a second operating group (9, 10) and a rest position in which the activation of the first operating group (12, 13) is disassociated from the second operating group (9, 10).

The present invention provides a novel cam-actuated spindle assembly for selectively attaching a cam follower to a capping spindle. By adjusting the assembly, the user can easily adjust a capping spindle to follow a selected one of different tracks that are formed into a barrel cam. This simplifies the process of adjusting a bottle capping or corking machine to accommodate a variety of products with different types and sizes of closures and bottles. The mounting assembly weighs considerably less than a spindle or barrel cam, and therefore, is considerably easier to reposition and adjust. There is no need to remove the barrel cam or change out the spindle, which significantly reduces costs, down-time, and manpower requirements. The mounting assembly is designed to be compatible with existing bottle capping equipment.

Control device, employing a follower member and a camtrack, for an element of a container processing machine, comprising two camtracks defined by a single rigid assembly, and means for producing relative movement between the follower member and the rigid assembly, between at least two positions, the follower member engaging with a first camtrack in a first position, and with a second camtrack in a second position. Blow moulding or stretch blow moulding comprising at least one such device, notably for controlling the movement of the elongation rod, or for locking/unlocking moulds, or for opening/closing moulds.

The present invention relates to a cam-operated device (5) for controlling at least one component, said device comprising a cam (6) comprising at least one first camway (7, 8) on a first face and a second camway (9) on an opposite face, said first camway (7, 8) having a depth, measured starting from an opening, at the level of said first face, of said first camway, and said second camway (9) having a depth, measured starting from an opening, at the level of said opposite face, of said second camway, a height of the cam (6), measured between the opening of the first and second camways, being less than the sum of the depths of the camways (7, 8, 9).

A gear shifting drum (2) for the gear shifting device of a motor vehicle variable-speed gearbox has a curved path (11a to 11c) for guiding a catch (13) of the gearshift fork (12a to 12c) and the gearshift forks (12a to 12c) are directly linked to a synchronisation device. According to the invention, at least one wall (9, 10) which extends outwards in the radial direction is provided on the outer surface (8) of the gear shifting drum (2) for forming the curved path (11a to 11c).
