A camshaft assembly support structure includes two camshaft assemblies including two shafts parallel to each other and cam pieces fitted on an outer surface of each of the two shafts, support members independent from each other and each including two bearings receiving the two shafts, the bearings each having a bearing surface seamless over an entire inner circumference, and positioning members each having a through hole receiving and tightly holding the shaft. The positioning members are positioned on both sides of each of the support members to position the support members in the axial direction of the shafts with the shafts being received in the bearings.

A unidirectional spring assembly for controlling a rotating rod. The unidirectional spring assembly includes a reduced disc mounted fixedly onto the rotating rod, a rotary clutch member, and a spring assembly. The reduced disc rotates synchronously with the rotating rod around a first axis. The reduced disc includes a concave surface and a push pin. The rotary clutch member includes a clutch arm and a circular slot on a side surface of the rotary clutch member. The spring assembly includes a guide rod configured to move along a second axis, a roller attached to a distal end of the guide rod, and a spring coupled to the guide rod.

A method for installing an adjustable camshaft may include inserting an adjustable camshaft in an installation device. The camshaft may include an outer shaft surrounding an inner shaft. The installation device may enable alignment of at least one cam rotatably mounted on the outer shaft. The method may include aligning the at least one cam by pushing an alignment pin through a radial passthrough opening in the at least one cam and through a drillhole in the inner shaft congruent therewith. The method may include non-rotatably connecting the at least one cam to the inner shaft by pushing a connecting pin into the passthrough opening and the drillhole in a direction opposite a direction the alignment pin was pushed. Non-rotatably connecting the at least one cam to the inner shaft may include detachably coupling the connecting pin and the alignment pin in a positive locking manner.

Engine and its camshaft, camshaft manufacturing method, the camshaft comprises a central shaft having an axial hole, the central shaft has a fitting section, the outer circumference of a cross section at any axial position of the fitting section is a polygon; a first cam and a second cam, the first cam and second cam are respectively installed on the fitting section of the central shaft and are spaced axially. Such a structure has the advantages of higher torque transmission, simpler structure, simplified manufacturing process, shorter manufacturing time consumption and reduced cost.

A cam assembly is provided for a pick-up reel of an agricultural harvester. The cam assembly includes a cam track, a roller bearing assembly, a crank arm, and a biasing member. The roller bearing assembly includes a baffle and first and second cam followers. The first and second cam followers are each mounted to the baffle in spaced apart relation and engaging the cam track. The crank arm is for mounting to the pick-up reel. The biasing member biases the roller bearing assembly relative to the crank arm.

The invention relates to a transport device comprising a transport element for receiving a workpiece, said transport element being movable by means of a motor from a first idle position into a second idle position, the transport element being drivably connected to at least one driver that engages in a drive groove of a drum cam that can be driven by the motor, which can be controlled by means of a programmable control device on the basis of a motor control curve. The drive groove has a variable incline at least in sections and the motor control curve also has a variable course at least in sections, the movement of the transport element being generated by a simultaneous superposition of a first movement component based on a region of variable incline of the drive nut and a second movement component based on a variable region of the motor control curve.

An axle disconnect apparatus having a cam cylinder including a ramp disposed in a radially outer surface thereof. A first clutch element disposed at least partially inside the cam cylinder and an intermediate shaft disposed at least partially within the first clutch element. The intermediate shaft includes a splined portion in constant mesh with the first clutch element. A half shaft may be disposed coaxially with the intermediate shaft, and a second clutch element may be coupled with the half shaft. The first clutch element selectively engages the second clutch element. The axle disconnect apparatus further comprises a latching mechanism whereby the cam cylinder maintains an axial position. The latching mechanism including a radial depression in the cam cylinder ramp, and a cam follower selectively disposed at least partially in the radial depression.
