Ashoka as one of a leading Bull Gear Manufacturers In India, In order for gears to achieve their intended performance, life and reliability, the selection of a suitable material is very important. Often not all design requirements are compatible. High load capacity requires a tough, hard material which is difficult to machine; whereas high precision favors materials that are easy to machine and, therefore, have lower strength and hardness ratings. Light weight and small size favors light non-ferrous materials, while high capacity requires the opposite. Thus, tradeoffs and compromise are required to achieve an optimum design. Materials vary widely, ranging from ferrous metals, through many non-ferrous and light-weight metals, to various plastics. The designer and user faces a myriad of choices. The final selection should be based upon an understanding of material properties and application requirement

Computer Aided Gear Designing. ASHOKA utilizes special computerized design generation software such as AUTOCAD, SOLID WORKS etc. for accurate designing of the gears and pinions. All software are generally updated to latest versions. Interference check and dimensional accuracies are also checked using these tools. ASHOKA generally works with client designs and drawings, however, all designs are checked and suggestive feedback given to the client for any possible improvement of the design.

At ASHOKA stagewise tests are carried out at various stages of manufactures of the ring gear production for which a complete check log in checked for reference. Third party tests agencies such as LLOYDS, SGS, DNV, TPL, MOODY etc. have often visited our factory for witnessing of above tests and subsequent qualitative clearance of the respective jobs. We welcome any third party agency in all cases.

General Gear Manufacturing Procedure Site Audit & Gear Inspection. The condition of girth gear is evaluated at site keeping in mind the remaining working life of the gear. Recommendations on existing gear life and requirement of new gear are made according to audit findings.

An appropriate mill grade of material in steels (alloy steels and carbon steels), irons (including graded irons, SG iron etc.) or bronze (generally phosphorus bronze) is selected based on the required mechanical properties in case the same is not specified by the client. We provide gears and pinions in cast and forged forms. Various international mill material standards are used including ASTM (USA), AISI (USA), BS (British), JIS (Japanese), GS (German), IS (Indian) standards.

Casting or forging under Gears Pinion Shafts Manufacturers, is produced keeping minimum necessary machining allowances on all relevant and required faces and surfaces. The casting/forging is volume heat treated in special enclosed furnaces with proper temperature controls for attaining the desired mechanical properties. Chemical testing is done using latest spectrometers, mechanical properties derived from test pieces using universal testing machines and hardness obtained using equotip type hardness testers.Non destructive testing to detect internal and surface flaws including Magnetic Particle Inspection (MPI) is carried out once after the casting is heat treated and ready for machining, where as, Ultrasonic Testing (UST) is carried out after proof machining of the job for accurate results.

Joint facing is carried out on all girth / split gears on each side of joints on the two halves on special horizontal floor borers (UNION, SKODA). Appropriate machining allowance is kept for finish machining in case further heat treatment is to be carried out that may create distortion on the job and hence variation in the sizes. In all such cases finish machining is done after the preliminary turning and heat treatment and in some cases even after one round of teeth cutting.
