Chain driven tapered rollers

Product catalog summary
Overview: The document provides technical specifications and guidelines for chain-driven tapered rollers used in curved sections of conveyor systems. These rollers are designed for efficient handling of curves with minimal space requirements.
Specifications: The rollers are available in light and heavy-duty versions, with fixed hexagonal spindles and M8 tapped ends. They are supplied in standard lengths with galvanized tubes. The document specifies dimensions such as inner radius (Ri), punching heights (h, h’), and other critical measurements for different roller types.
Assembly Instructions: Proper assembly is crucial, with specific positioning of rollers as illustrated in the document. The frames should have slots to adjust the chain tension effectively.
Designation: Each roller is designated by a code, finish reference, and length in mm. Examples of designations are provided for clarity.
Load Capacity: Load capacities are detailed for various RPMs, with specific values for each roller type. The document also references the load capacity of base rollers for those with polypropylene inserts.
Curve Dimensions: The document includes graphical construction of curves, emphasizing the importance of maintaining specific angles and distances between rollers. Nominal dimensions for 90° curves are provided, considering the most common motorization center distances.
Additional Notes: All dimensions are subject to machining tolerances. The manufacturer reserves the right to modify products without notice, and reproduction of the document's content is prohibited.

Chain driven tapered rollers-2

RULLI COMANDATI CON CATENA PER CORSIE CURVE RULLI CONICI LEGGERI COMANDATI CON CATENA These tapered rollers are used for curves in chain driven roller conveyors when small radii are required. They have fixed exagonal spindle at one end, M8 tapped at the other. They are available only galvanized (ZB execution) and in standard lengths. The holes on the outside frame of the curve allow regulating the tension of the chain links (see drawings 1 and 3). The opposite exagonal bores (drawing 2) prevent spindle rotation. Rollers must be properly assembled as shown in the drawing of page 8. The table of...

RULLI COMANDATI CON CATENA PER CORSIE CURVE DIMENSIONI DELLE CURVE COMANDATE CON CATENA Riportiamo la costruzione grafica di una curva a rulli conici comandati con catena, nella quale si tiene conto del comando con anelli di catena in serie. Per questa motorizzazione si ammette un angolo max. fra gli assi dei rulli di 5°. Si noterà che per ottenere lo stesso interasse E su due archi diversi R’ ed R”, si determinano due angoli al centro diversi, che sono rispettivamente B’ e B’’. Questa geometria richiede una foratura con interasse alternativamente maggiore (e’-i’) e minore (e”-i”) sui longheroni....
