Abstract: A driving mechanism of a wave-producing ornament is mounted in a base of the ornament and includes a motor which rotates a disc. A connecting link is pivotally connected at a first end to an outer periphery of the disc and at a second end to a lower end of a push bar. The push bar is located in a channel integrally formed on the base of the ornament and has a round head projects from a top opening of the channel to contact with an end of a liquid container of the ornament above the base. When the disc rotates, it brings the connecting link to move in a circular motion and pull and push the push bar to descend and ascend along the channel reciprocatingly. Whereby, the liquid container is periodically lifted and lowered at one end by the round head of the push bar to produce waves in the container.

The first drive system can move the rotary table into a starting position and the second drive system is a linear one and has a play-free pre-loaded ball-and-screw spindle drive by means of which the movement of the rotary table is performed within the predeterminable angular segment. The linear drive system can be coupled and uncoupled free from play to and from the rotary table by means of a clamping system, with the linear drive system being connected to the support member and to the clamping system with two play-free joints. A rotary measuring system is mounted at the axis of table rotation to ascertain the table's current angle of rotation.

Abstract: An eccentric bearing includes inner and outer race rings, an eccentric ring positioned between the inner and outer race rings, two spaced apart rows of roller elements positioned between the inner race ring and the eccentric ring, and two spaced apart rows of roller elements positioned between the eccentric ring and the outer race ring. An adjustment lever is positioned adjacent one side surface of the eccentric ring and is mounted on a link pin that is positioned in a bore in the eccentric ring. The link pin is axially fixed in place by a tie bolt that extends through the bore in the eccentric ring. The link pin includes a conically shaped mantle surface that engages a correspondingly shaped portion of the bore in the eccentric ring, thus achieving a tight seat with a large surface at the point most at risk, i.e., the point where the link pin exits at the side surface of the eccentric ring.
