Assembly workers and technicians often use rotary assembly tables. Once the components are installed, the assembler will turn the workbench to complete the next work step without having to change his position. Finding the best settings for each rotation is important, as adjustments made every month can quickly add a few hours. Especially at the end of the shift, attention may be weakened, which may cause the workbench to turn too far and miss the work steps. This can lead to expensive rework. "In order to solve these problems, we have added a new locking function to the PRT-04 series of rotary table bearings," said Dean Aylott, product manager of the PRT slewing ring business at igus UK. "It's a relatively simple mechanical device, but it's very effective." Never forgetting a work step PRT-04 The lock function of the turntable bearing is easy to use. Before turning, pull the spring bolt by hand. At the next locking point, the default is every 90 degrees, the bolt is re-clicked after rotation and the bearing is firmly fixed in place. Users no longer waste time making further adjustments. In addition, the locking point can be set individually. So, for example, in an engine assembly, the operator can rotate the bearing table by 20° to screw the glow plug into the engine, and then rotate it by 70° to insert the dipstick. The card returns to its original position so that you will not forget a step. The PRT-04 with locking function is part of the integrated module. The system has a small installation space specially developed for loads up to 48,000N. This allows the customer to configure his/her personal iglidur PRT slewing ring bearing in one of eight sizes from 20 to 300 mm. In addition to accessories such as drive pins, variable mounting plates and clamping rods, igus also provides three external gears and internal gears for limited installation space. The slewing ring bearings can be driven by toothed belts or gears, which are injection molded from a friction-resistant polymer. Like all slewing ring bearings, igus uses radial and axial sliding elements between the inner and outer rings of the bearing. Lubrication-free sliding elements made of high-performance plastic iglidur J ensure that friction and wear are minimized; not only when using ready-to-use systems in assembly stations, but also in control panels or stage and lighting technology in the theater and film industries.
