Outer Diameter from *0 mm/0.*5" to ***0mm/*0" Face Widths upto **0 mm/*1" In Single or multi starts Center Distance from *5mm/1" to **0mm/*0" In Cast Iron, Bronze (PB2S), or as specified standard and custom made as per Specifications, Drawing or Sample Worm Gears available on very tight delivery schedules, some Worm Wheel & Worm shafts Pairs like for Worm Gear Boxes (most of the makes) of C.D. *0, *0, *5, *5, **0 mm, Ratio *0:1 or *0:1 are usually available Ready-Stock. Other ratios are also available within One day of placing Order or on short notice (subject to conformation). Gear Box Overhauling and Rebuilding Services Worm gear and worm shaft pair speed reducers are right angle speed reducers used in applications usually involving low horsepower. Worm gear set maintain high gear ratios, low or nearly nil gear play or backlash, high shock tolerance, and compact design. Worm gears provide a normal single reduction range of 5:1 to ****1 and can go easily upto **7:1 or more under rare circumstances. The pitch line velocity is ideally up to *0 m/s. The efficiency of a worm gear ranges from *8% for the lowest ratios to *0% for the highest ratios. As the frictional heat generation is generally high the worm box is designed disperse heat to the surroundings and lubrication is and essential requirement. Worm gears are quiet in operation. Worm gears at the higher ratios are inherently self locking - the worm can drive the gear but the gear cannot drive the worm. A worm gear can provide a *0:1 speed reduction but not a 1:*0 speed increase. In practice a worm should not be used a braking device for safety linked systems xxxxx hoists.
