Bending - Import export

The UBM 6-20 M is a universal bending device for steel pipes up to 20 mm OD. It comes with a set of bending rolls for common applications. An integrated scale for angle detection helps you to reach the required pipe dimension in only one work step. The telescopic lever keeps the operator’s forces low when bending rigid pipes. •Compact design •Compact for mobile usage •Standard with a set of 6 bendings rolls •User friendly •Easy handling •Simple adjustment •Wide workpiece range •Innovative design •Angle scale included •Telescopic lever

This version of the RfN 7015 is designed for high bending load applications such as conveyor pulleys, by providing lower shaft and hub pressures. If the pressures are too high for the application please note datasheets Mb 20% - Mb 80% with reduced bending moments. Characteristics Version of the Locking Assembly RfN 7015.0 with lower surface pressure for reduction of the stresses at soft end discs. Explanation to table A bending moment, created by radial forces, results in an additional load for the Locking Assembly, shaft and hub. This load creates an additional pressure, works in rotation and has to be superpositioned with the pressure resulting from the Locking Assembly. For a viable connection, a minimum surface pressure at the contact areas between Locking Assembly, shaft and hub must be maintained, as soon as shaft and hub have to take up the maximal pressures. Additionally, the listed torque values (T) have been reduced due to the additional bending moments. To achieve...

Especially for the bending moment transmission designed 3 part Locking Assembly with reduced stresses in the Locking Assembly itself. Special Features - Through the long and flat cones one Locking Assembly RfN 7515 can transmit torques and axial forces and bending loads. At mounting is a small axial movement from Locking Assembly and hub. Bending moment and radial loads – combined loads can be transmitted (Please contact our specialists for assistance). Excellent centering ability – with a relatively wide design. Example applications: Belt drums, gear wheels If the pressures are too high for the application please note datasheets Mb 20% - Mb 80% with reduced bending moments.

For superb centering and high torque transmission, this dual tapered device reflects the best in RINGFEDER engineering expertise. This style is in two types, 7015.0 for general engineering applications and 7015.1 for conveyor pulley applications. Available in sizes 100 to 600 mm.

The new Locking Assembly series RINGFEDER ® RfN 7012.2 is specially designed to fulfil the requirements of constantly increasing bending moments for conveyor pulleys. The challenge was to develop a product with the same dimensions as the standard RINGFEDER ® RfN 7012 to fit into existing end discs – Attention: yield point of end disc has to be checked – so that also material handling equipment at hand can be upgraded. At the same time the Locking Assembly should carry a multiple of the bending moments of the standard RINGFEDER ® RfN 7012. If the pressures are too high for the application please note datasheets Mb 20% - Mb 80% with reduced bending moments.

Typical belt drum application The bending moment acting on the hub/shaft connection is the main load to evaluate in a belt drum or similar application. Excessive bending moments can cause overstress in the webs between the screw holes in the locking assembly. In the case of additional loads (bending moments/ radial loads) screw tightening torques may have to be reduced. To limit the influence of the bending load on the locking assembly connection we use the following criteria during the belt drum design process: - Shaft deflection from the bending moments can only have a maximum deflection fm < 1/2000 * L (bearing centre distance). - For the permissible bending load values please refer to our tables. If the pressures are too high for the application please note datasheets Mb 20% - Mb 80% with reduced bending moments. One of the most demanding challenges of our promise of performance is the conveyor pulley application field. The extreme loads which such components are subject...
