SHACON WORM GEAR BOXES

SHACON WORM GEAR BOXES

About Our Products SHACON WORM REDUCTION GEAR BOXES are convenient, efficient and economical means of power transmission. SHACON Gear Boxes incorporate advanced designs and are manufactured by specialized techniques. Standardised sizes developed facilitate interchangeability of gear boxes and spares. Design : SHACON Gear Boxes incorporate worm gearing that conforms to National / International standards. Derived from our experience and based on the development efforts of our engineers, valuable modifications have been incorporated to obtain rugged, silent, efficient and long lasting gearing. Generously sized bearings and shafts sustain external loads and increased life of gear boxes. Box type gear case with ribs used in SHACON Gear Boxes have proved to be capable of handling heavy duty loads and highly efficient to radiate heat thus increasing power transmitting capacity of the gear box. Worm Shaft : selected steel is used for worm shafts for increased strength and life. Precision machined involute thread form used make gearing more efficient and silent running. nalised metric sizes of shaft extensions are available as standard. Worm Wheel : Smaller worm wheels are of single piece construction and made out of chilled cast high grade Phosphor Bronze. Larger size worm wheels are made out of centrifugally cast high grade Phosphor Bronze rims shrink fitted on CI center and positively secured by special pegs. Finely distributed and refined grains of Bronze matrix give high impact strength, reduce friction and subsequent heating and increase life of gearing. Worm wheel teeth profiles are generated by specially developed Hobbing and Reaming cutters to obtain true conjugate action between worm thread and worm wheel teeth thus ensuring high load carrying capacity, silent running and efficient power transmission. Each and every worm wheel is inspected on a specially developed gear checker to ensure adherence of quality standards and interchangeability between any worm and wheel of that size and ratio. Specialised assembly methods used to obtain optimum tooth bearing contacts and proper bearing per-loads for actual conditions of the gear boxes when in service. Output Shaft : In a standard SHACON Gear Boxes this is made out of quality plain carbon steel and precision machined. nalised metric sizes of shaft extensions are available as standard. Gear Case : This is made out of fine quality cast iron and accurately machined with the help of jigs and fixtures to ensure accuracies of important parameters, ease of maintenance and interchangeability of spares. Bearings : Generously sized dual purpose bearings are used to sustain gearing and external shaft loads for longer life. Lubrication : SHACON Gear Boxes have built-in splash lubrication system that splashes and cools the oil effectively. On larger size gear boxes this is further assisted by an external cooling fan. Quality Assurance : It has been our endeavour at SHACON to manufacture the products worthy of money the buyer spends and hence all the products we manufacture undergo quality and inspection checks governed by our quality assurance scheme. This scheme provides for the purchase of materials to testing of every assembled gear box. Special custom built gear boxes : We also undertake design, development and manufacture of special worm gear boxes such as aeration cone gears, lift gears, cooling tower gears, agitator gears, tube mill gears etc.
