A torque drive transmission, having at least two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams are operative to: (i) convert a linear input to a rotary output, and (ii) drive a pair of coaxial drive shafts in opposite directions along the rotational axis. Furthermore, each counter-rotating cam defines a cam profile surface having drive and follower surfaces defining angles and respectively. The angles and are unequal to drive each cam and respective output drive shaft in an opposite rotational direction. As such, the cams may be driven in opposite directions irrespective the initial rotational position of the linear input, i.e., relative to each counter-rotating cam.

A drive transmission has two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams have asymmetrical lobe profiles which are operative to drive a corresponding pair of coaxial drive shafts in opposite directions along the rotational axis. The asymmetry of the lobe profiles prevents the cams from locking when the lobe apexes pass the top and bottom dead center positions relative to the follower or drive pins.

A method for producing a ready-for-use camshaft for controlling valves of an internal combustion engine may be directed towards camshafts that include a carrier shaft on which an end component, for example, a drive wheel, a phase adjuster, or a part of a phase adjuster, is arranged and cam elements that are attached in a positionally fixed manner to the carrier shaft. In some examples, the method comprises providing a carrier shaft and an end component, joining the end component to the carrier shaft, grinding at least the carrier shaft to form cam seats so as to establish readiness for use, introducing a surface profile into a first cam seat, providing a cam element with ready-for-use characteristics, seating the cam element on the cam seat with the surface profile, and repeating certain steps for additional cam elements.

A cam device includes a cam, a cam roller, a rotary drive device, a linear motion guide device, and an action unit. A cam profile of the cam includes a rotary end at a circumferential one end, at which a camshaft is non-rotatable in a reverse direction by the cam roller, a cam surface from the rotary end to the circumferential other end, on which the cam roller is abuttable, and formed of a single CV curve from a vicinity of the rotary end to the circumferential other end of the cam surface, and a non-continuous section formed between the rotary end and the circumferential other end of the cam surface and not in contact with the cam roller.

A dishwasher system for cleaning dishes may include at least one rack configured to receive a silverware basket, the basket including at least one silverware compartment, a pair of camshafts including a first camshaft and a second camshaft, each fixed to the rack and operable by a gearbox configured to rotate the camshafts with respect to the rack, the camshafts arranged below the silverware basket, and a cam arranged at each end of each of the camshafts, wherein upon rotation of the camshaft by the gearbox, the cams affect the height of a respective corner of the basket to allow the silverware therein to be lifted or lowered and exposed to spray at various heights or angles from sprayers within the dishwasher.

A device for assembling cams on a camshaft pipe of a camshaft may include a first gripper and a second gripper each configured for gripping and holding a respective cam. The first gripper and the second gripper may receive the respective cam in a common direction and may be movable in a common direction into alignment with respect to the camshaft pipe. The second gripper may be configured to grip and hold the respective cam that is pivoted by 90 with respect to an orientation of the respective cam in the first gripper.
