A vibratory assembly has a power source with a rotational output, an implement configured to work uncured concrete, and a vibratory head means for receiving a rotational input from the power source and converting the input from the power source into mechanical oscillation and to transfer the mechanical oscillation to the implement.

This disclosure is drawn systems, devices, apparatus, and/or methods related to the separation of a mixture of solids according to size and the separation of solids from liquid. Specifically, this disclosure is drawn to an adjustable weight set for use on vibratory separators. In some examples, the adjustable weight set may include a base plate rotatable about an axis and extending radially outward from the axis; a plurality of slots extending through the base plate and being disposed between a radially outward periphery of the base plate and the axis; a plurality of weights coupled to each other about the base plate; and a weight locking tab that partially surrounds the base plate that may include one or more hooks extending through a portion of a slot.

A vibration device for generating various vibration signatures or characteristics is provided. This various vibration signatures or characteristics allow a single vibration device to be used to test and replicate failures in a subject device across a broad range of vibration signatures or characteristics transferring to the subject device. The vibration devices includes a pair of spaced-apart plates, each defining a slot therein. An adjustable fastener connects the upper and lower plates and extends through the upper and lower elongated slots. A vibrator is fastened to the upper plate via the upper elongated slot. To enable the vibration signatures or characteristics to be varied, the fastener is adjustable in a vertical direction to alter the distance between the lower plate and the upper plate, and is adjustable in a horizontal direction along the upper and lower slots. The motor can also translate along the upper elongated slot.

A vibratory drive system comprises a rotatable drive shaft and an out-of-balance wheel that is coaxial with and rotatable relative to the drive shaft. A rotary transmission system couples the drive shaft to the wheel in order to transmit rotational movement of the drive shaft to the wheel. The rotary transmission system comprises a shaft gear, a wheel gear, and intermediate gears coupling the shaft gear to the wheel gear. The intermediate gears are carried by a gear carrier that is rotatable relative to the drive shaft, and are rotatable with respect to the gear carrier. The arrangement allows the phase angle of the out-of-balance wheel to be adjusted with respect to the drive shaft.

A tamping beam device of a paving screed, in particular of a road paver, with a tamping beam, which is arranged on at least one connecting rod, with a drive shaft, which is connected to the connecting rod via an eccentric device. The eccentric device is configured such that a first and a second stroke setting of the tamping beam can be adjusted by means of a thrust member that is axially adjustable on the drive shaft. The thrust member comprises a first region, which is arranged in the eccentric device, and a second region, which is arranged outside the eccentric device. The second region is connected to an axial adjustment device via a thrust bearing. A paving screed and a road paver having such a tamping beam device. A method for changing the stroke of a tamper beam device.
