Drive alignment laser

BMG’s extensive range of Fenner power transmission components and instruments includes the Fenner Drive Alignment Laser, designed for accurate pulley and sprocket alignment in order to reduce wear on belts and pulleys and ensure drive efficiency. Carlo Beukes, Business Unit Manager, Power Transmission at BMG, says, “The portable Fenner Drive Alignment Laser sys- tem – which is suitable for both vertical and horizontal mounted machines – is quick and easy to use and delivers accurate results. It is a compact and lightweight tool and the la- ser line allows rapid adjustment to perfect alignment. Conventional alignment meth- ods, which often require difficult, lengthy po- sitioning of components, can prolong down- time and affect efficiency. “The Fenner alignment system shows parallel and angular misalignment,” says Beu-

kes. “As a result, drive efficiency is improved and energy savings can be increased. With minimal friction and vibration, the service life of chain, sprockets, shafts and bearings is significantly extended and the costs of main- tenance, repair and downtime are reduced.” For maximum accuracy, the mounting unit is magnetised to attach firmly to sheaves or pulleys. It is also possible to attach this in- strument to non-magnetic sheaves simply using double-sided adhesive tape. BMG’s Fenner range includes synchro- nous transmission belts, pulleys and acces- sories, as well as shaft fixings, chain drives and couplings. The company also supplies Fenner shaft-mounted speed reducers (SMSRs). Enquiries: Carlo Beukes at BMG. Tel. +27 (0)11 620 7558, or email: carlob@bmgworld.net

Optimising OEMs’ costs for engineering machines

and through the life cycle of the machine. For simplified installa- tion, book and compact form factors reduce the machine footprint and allow efficient space usage, whether the machine is mounted in a frame or installed in an electrical cabinet. Fewer additional devices are needed to manage the machine safely and repeated sequential movements are managed internally within the drive. Printed circuit boards are class 3C3 coated, in accordance with IEC 61721-3-3, to protect against corrosion in harsh environments. The drives maintain a thermal state allowing uninterrupted oper- ation with ambient temperatures up to 60 °C. Integrated safety features include a safe stop and speed control as well as a guard door locking device. The system is suitable for applications in materials handling, packaging, the textile industry, mechanical actuators and hoisting. Magnet supports the Altivar ATV320 range with a technical ad- visory and installation service throughout Southern Africa.

Magnet supplies a range of Schneider energy management and automation systems which includes the Altivar ATV320 variable speed drives (VSDs). This system, developed to improve a ma- chine’s performance in diverse applications, also supports the op- timisation of design and engineering costs for original equipment manufacturers. “Schneider’s range of variable speed drives – with simple plug- and-play commissioning – meets simple and advanced application requirements for three phase synchronous and asynchronous mo- tors from 0,18 to 15 kW,” says Brian Howarth, Managing Director of the Magnet Group. “The Altivar ATV320 drive, which combines safety, reliability and simplicity, is used for building more effective machines, with greater reliability, at optimised costs.The drives provide for contin- uous machine operation, even in harsh environments with elevat- ed ambient temperature levels, dust, electrical interruptions and mechanical disturbances. “Schneider drives also maximise machine operating time be- cause production changes, maintenance, safety diagnostics, net- work configuration and system integration can be accomplished quickly,” says Howarth. Altivar ATV320 drives meet various machine throughput re- quirements, including open loop motor control, with dynamic accuracy for start/stop applications and torque-sensitive opera- tions, even at low speed. Closed loop motor control is offered for applications requiring velocity-sensitive operation or precise positioning. The drive system offers advanced connectivity with automation architecture via all common fieldbuses, in real time, with fast task cycle times. The Altivar range is designed for easy integration with various machine layouts. It reduces total machine costs during installation

Altivar ATV320 variable speed drives are designed to improve machine performance and allow for optimising OEM engineering costs.
