Oscillating Conveyor Technology

Guided Oscillating Systems

Guided oscillation refers to the channeling of momentum to impart movement in a defined direction, as is the case with shaker/rocker conveyer systems. 
Examples include tobacco shakers and shuffle conveyer.

Type AD-C

The ROSTA double suspension units type AD-P/AD-C are used for suspending and supporting two-mass shaker systems. The centre point, for frame fixation, is in the middle of the double rocker arm.

The AD-C model is designed to be frictionally engaged in the same way as the AS-C type. The housings and the inner square sections are made of welded steel. The inner square section of the AS-C type are made of aluminium profile.

Type AD-P

The ROSTA double suspension units type AD-P/AD-C are used for suspending and supporting two-mass shaker systems. The centre point, for frame fixation, is in the middle of the double rocker arm.
The AD-P suspension units are mounted by means of fixing flanges.

The housings and the inner square sections are made of welded steel. The core of the AD-P type is equipped with fixing plates constructed analogously to the AU type.

Type AK

The ROSTA universal joints type AK are maintenance-free elastic joints which can be moved in any direction. They are used as universal joint supports for mounting or suspending gyratory screens, screening tables, tumbling oscillators, sorters and screening machines positively driven by eccentrics or freely oscillating with unbalanced drive.

The types AK 27 until AK 100-4 have got housings made of SC iron, all the other sizes are made of welded steel structures. The types AK 15 to AK 50 have got aluminium square sections, the other sizes have steel cores.

Type AR

The ROSTA oscillating mountings type AR are maintenance-free elastic joints used for the same purposes as our other oscillating mounting types AU, AS or AD. The distance between the centres can be freely chosen. The commercial circular tube (connection between the two elements) must be supplied by the customer. The inner square profile is frictionally engaged to the machine frame, analogously to type AS-C and AD-C.

The housing of mounting type AR is made of cast aluminium, the core is made of aluminium profile.

Type AS-C

The ROSTA rocker suspension units type AS-P and AS-C are maintenance-free elastic guide arms used for the same purposes as the oscillating mountings type AU. This low cost model is suitable for fixed distances between the two bearings (rocker length A). The AS-C types are designed to be frictionally engaged to the machine frame. The central mounting allows an easy adjustment of the rocking angle.

The housings are made of welded steel. The inner square section of the AS-C type is made of aluminium profile.

Type AS-P

The ROSTA rocker suspension units type AS-P and AS-C are maintenance-free elastic guide arms used for the same purposes as the oscillating mountings type AU. This low cost model is suitable for fixed distances between the two bearings (rocker length A). The AS-P types are mounted on the trough or the machine frame by means of fixing flanges.

The housings and the inner square sections are made of welded steel. The core of the AS-P type is equipped with fixing plates which are similar to the ones of the AU type.

Type AS-PV

The ROSTA rocker suspension units type AS-PV and AS-C are maintenance-free elastic guide arms used for the same purposes as the oscillating mountings type AU. This low cost model is suitable for fixed distances between the two bearings (rocker length A). The AS-PV types are mounted on the trough or the machine frame by means of fixing flanges.

The housings and the inner square sections are made of welded steel. The core of the AS-PV type is equipped with fixing plates which are similar to the ones of the AU type.

Type AV

The ROSTA oscillating mountings type AV are maintenance-free elastic joints designed for guiding circular motions of hanging screens such as gyratory sifters and screens in flour mills, chemical processing plants and paper mills.

The rubber inserts of these oscillating mountings are larger than the ones of the other ROSTA elements. Therefore they intensively absorb the vibrations of the hanging sifters and better protect the building structures and ceilings.
All these mounting types have got housings made of cast aluminium; only type AV 50 has got an SC-cast-iron housing.
The cores are all made of aluminium profiles, also the size AV 40 and AV 40L. We start to produce the elements with the inner square made of light metal profile approx. within February 2014. All the dimensions are kept, that means the elements are fully adaptable with the previous version. The previous version is still available as a special element.

Type ST

ROSTA oscillating drive heads type ST are flexible joints transmitting the acceleration forces from eccentric drive to the oscillating machine part - free of play, silently, reliably and without requiring maintenance. The common maintenance problems which are characteristic of these drive components are thus eliminated.

The inner square section (core) and the trough are joined together by a so-called "fork". The outer housing is screwed to the slider crank rod and locked. Right- or left-hand threads are available, which allows the crank length to be adjusted easily. The drive heads up to type ST 45 have got an aluminium housing and core; type ST 50 has a housing made of SC iron and an aluminium core; ST 60 and ST 80 have an SC iron housing and a steel core.

The common maintenance problems which are characteristic of these drive components are thus eliminated.

The inner square section (core) and the trough are joined together by a so-called \"fork\". The outer housing is screwed to the slider crank rod and locked. Right- or left-hand threads are available, which allows the crank length to be adjusted easily.
The drive heads are made out of aluminium.
