The catalogue is printed on FSC® certified paper, demonstrating Rulmeca's dedication to environmental sustainability. FSC® certification ensures responsible forest management.
The catalogue includes a variety of components for internal logistics, such as rollers, drum motors, and 24VDC drive rollers, designed to improve system performance and reliability.
- Rollers for Gravity Conveyors: Includes series like GL, 111, 117, designed for noiseless applications.
- Components: Features wheels, minirail, medirail, heavyrail, omnidirectional wheels, ball transfer units, speed controllers, and profiles.
- Rollers for Chain Driven Conveyors: Includes pinion sprocket driven rollers and crown sprocket driven rollers.
- Rollers for Belt Driven Conveyors: Covers grooved rollers for round belt transmission and Poly-V belts.
Guidelines for product selection and application include code designation, measurement units, and plastic materials information. Design criteria for various conveyor systems are also provided.
Rulmeca invites feedback and inquiries via email at [email protected].
- Angle Measurements: Conversions between radians, degrees, minutes, and seconds.
- Speed and Angular Speed: Speed in meters per second (m/s) and feet per second (ft/sec), angular speed in radians per second (rad/s) and revolutions per minute (R.P.M.).
- Torque and Power: Torque in Newton-meters (N·m) and pound-inches (Ib·in), power in watts (W), horsepower (H.P.), and cavallo vapore (CV).
- Electrical Measurements: Units for electric current (ampere, A), voltage (volt, V), and frequency (hertz, Hz).
- Pressure: Pressure in pascals (Pa) and pounds per square inch (psi).
- Introduction: RULLI RULMECA has used polymers with steel for over 40 years, offering economic advantages over aluminum and stainless steel.
- Advantages of Polymer Rollers: Noise reduction, shock resistance, lightness, minimal starting resistance, and corrosion resistance.
- Applications: Suitable for loads up to 200 kg, beneficial in environments requiring easy cleaning, like the food industry.
- Material Properties: Details on polymers like polyamide, polypropylene, and PVC, highlighting mechanical and chemical resistance.
Discusses load distribution, emphasizing that nominal values should not be taken at face value. Load should be divided based on contact points and surface rigidity, affecting deflection and stress levels.
Ensures load capacity (Pc) is greater than or equal to the applied load (P). Environmental conditions and tube thickness must be considered, especially for concentrated load shocks. Larger diameter rollers can reduce thrust force or inclination in gravity conveyors.
Careful estimation of slope is necessary to ensure packages restart after pauses. Heavy packages require speed regulating rollers for long distances, and fragile packages may not be suitable for gravity conveyors.
Proper alignment, parallelism, and squareness are essential for efficient operation. Special applications may involve inclined rollers or omnidirectional wheels for package alignment and direction.
Describes different shaft executions for roller installation, including spring-loaded shafts for easy installation and shafts with internal or external threads for fixed ends.
Outlines the calculation of the supporting structure based on an equally distributed load, with key parameters including total load, deflection resistance, moment of inertia, span distance, and elasticity module.
Defines chain-driven roller conveyors, detailing components like the chain, rollers, chain guard, and chain guide. The direction of transport is determined by gear rotation, with tensioners compensating for chain length variations.
Discusses two main transmission systems: simple tangential chain version (P1C) and chain loops version (P2C), suitable for ambient temperatures from -5°C to +80°C and speeds up to 0.5 m/s.
Designed for heavy unit handling, featuring steel tubes welded to pinion sprockets and swaged at the idle end. Bearings are permanently lubricated and protected by polypropylene caps.
Divided into static and dynamic categories. Static load capacity considers shaft and tube deflection, while dynamic load capacity is related to rotating speed, calculated for a 10,000-hour lifespan.
Allow unidirectional drive, ideal for loading or unloading at higher speeds than the conveyor. The free wheel is mounted on a special end-cap with a 6201 ball bearing.
Designed for light and medium loads, transmitting motion through friction. Available in zinc-plated steel or PVC, with pinions in Polyamide or steel.
Provides detailed specifications for rollers used in chain-driven conveyors, with ordering codes including type, shaft diameter and execution, tube diameter and execution, and length "C".
Constructed using various materials, including Polyamide for pinion sprockets and options for stainless steel bearings (AISI 440) and antistatic versions.
Describes several series of rollers, including Series 1382, featuring friction rollers with Polyamide pinion sprockets for simple tangential chains (P1C) and chain loops (P2C).
FDN and FDR series designed for heavy loads, featuring double friction and adjustable double friction capabilities.
Guidelines for correct positioning of rollers and construction of side frames for chain-driven tapered roller curves.
Legend for execution codes used in roller manufacturing, such as R for drilled and threaded shafts, J for zinc-plated shafts, and I for AISI 304 stainless steel shafts.
Discusses availability and specifications of Poly-V belts, including transmittable torque and pretension requirements.
Fixed and friction-driven rollers with toothed belt heads, compatible with Poly-chain GT belts and HTD belts.
Tapered rollers with grooves for round belt transmission, constructed using polypropylene cone sleeves and precision radial bearings.
