國際：印度螺旋傘齒輪公司概況（Gears and Pinions）
原文：Since our inception four decades ago, we have set new standards for the gear manufacturing industry by adopting the latest technology, optimally utilising our production capacities and adhering to stringent quality checks.
Apart from specialising in the manufacture of Spiral Bevel Gears, we also make Angular, Hypoid and Straight Bevel Gears. We also have the facility to manufacture ground Spline Shafts. Over the last few years, Spiral bevel gear sets, have been regularly exported to America, UK and Iran.
Our state-of-the-art design center, manned by specialists in CAD/CAM, is equipped with the latest equipment to ensure quality design and processes. The various manufacturing processes are computerized to ensure quality components, with a high level of consistency.
Our recently enhanced production capacity enables us to cater to all your needs. Our emphasis on quality, competitive pricing & just in time deliveries, assures you of the best Gears, competitively priced and quickly delivered.
原文：In our integrated-manufacturing cycle the blank goes through various processes while being transformed from the raw material to the end product. Each stage in the manufacturing cycle has in-built quality checks which ensure that the end product will conform to all relevant quality parameters.
Here the forged blanks are turned to suit the drawing requirement on CNC machines. Necessary supporting equipments for drilling, tapping, broaching, key-way slotting etc. are also installed.
Gear Cutting Department
The Gleason Five Cut method is followed for Spiral Bevel Gears and Crown Wheel and Pinions manufacturing. Our products conform to AGMA standards. Gears are cut by using the Generation or Format method and Pinions are made using the Three Cut Gleason Cycle.
Before the cutting commences, the cutter blades are mounted on the cutter head and trued radially and axially.
The re-sharpening of the blades are done on special purpose cutter grinding machines.
Straight Bevel Gears are cut on machines using the Coniflex System. This system of cutting ensures high productivity and good surface finish.
Cutter blades are re-sharpened radially and axially on special purpose cutter sharpening devices.
Spline Hobbing & Thread Milling:
Splines are hobbed on imported Spline hobbing machines and threads are milled on imported special purpose thread milling equipment.
In our recent expansion program we have installed the latest machinery for internal, cylindrical spline and surface grinding.
The internal diameter of hardened crown wheels are ground by holding the component in pitch line chucks to ensure accuracy of the finished gear.
Heat Treatment Department
Each component is gas carborised in an pit type furnace, then hardened in oil electrical degreased and then tempered. The component is then shot blasted.
To ensure low distortion while hardening, Crown Wheels are press quenched i.e. the component, while hot, is held in a custom made die and immersed in quenching oil. Care is taken to ensure that the part is always pressed under controlled pressure while being quenched.
Some components are cooled to sub-zero temperatures, using special application low-temperature equipment, to get better micro structure. Some components are sharpened to get better life and stress control.
To ensure smooth and quiet running, the Gears and Pinions are lapped after hardening. Lapping is accomplished by running mating pairs together in a Gleason Hypoid lapping machine and feeding a liquid abrasive compound under pressure into the gear pair. The compound removes small amounts of metal as the gears rotate, thus refining the tooth surface and achive desired contact pattern.
