Reliance Gear Co. Ltd Offers Picture Perfect Scanning with Reli-a-Flex(TM) High Torsional Stiffness Coupling
With the latest advances in digital optical scanning speed, professional flatbed scanner manufacturers are requiring more accuracy from their drive systems. A European company with leading edge technology in drum and flatbed scanners, image setting and integrated media processor products uses Reli-a-Flex(TM) couplings in all their flatbed products. With XY technology, speeds of up to 50 scans per hour and resolutions of up to 5400 dpi, the accuracy and reliability of the Reli-a-Flex(TM) coupling makes it the ideal choice.
Prior to the introduction of the Reli-a-Flex(TM) coupling slight variations in the speed of the CCD element caused errors when trying to capture high resolution images. These errors manifest themselves as a colour registration defect, which resulted in an unacceptable banding effect across the image. Although these errors were small (typically 3.0 microns) they could easily be detected by the naked eye.
The cause of these errors was identified as the flatbed drive system. Introduction of a Reli-a-Flex(TM) coupling manufactured from low inertia Grade 7075-T6 Aluminium was instrumental in bringing these registration defects under control. The unique slit pattern with radial rather than spiral slits gives the Reli-a-Flex(TM) coupling high torsional stiffness and unsurpassed accuracy. However, with Reli-a-Flex(TM) high torsional stiffness does not mean high bearing load, the Reli-a-Flex(TM) slit pattern has been carefully designed to give low bearing loads in conjunction with its high torsional stiffness.
Also, being tested to 50 million cycles at rated torque, the Reli-a-Flex(TM) is ideal for high duty cycle applications such as busy printing and typesetting applications. All in all the Reli-a-Flex(TM) has proved itself to be ideal for accurate positioning and responsive servo systems.
