Industrial Gears

Mechanical Gears



People often looked for constant technological advancement to gauge the progression of a piece of equipment. One noteworthy evolution in the last 50 years is of mechanical drive. Trenchers used to put stuffs in the ground gradually shifted over the last several years to mechanical drive. Mechanical drives used gearboxes, shafts, pulleys, chains and sprockets to drive the trencher chain. Mechanical gear are used to provide a variable output speed from a constant speed power source or to provide torque increase for a variable speed power source as in an automobile. Mechanical drives are less costly than competing electrical drives and their control is much simpler. The disadvantage of these drives is that they are not durable and cannot be controlled as precisely as electrical drives. They cannot transmit as much power as electrical drives when variable speed is essential. They are used in industries ranging from aerospace to mining and heavy industry. With the advanced technology, the working of mechanical drive has become more efficient. Specific characteristics like low-stress, universal mounting, high-strength monobloc casings, high-energy efficiency and low noise level are designed. The monobloc design has increased center distances between the output shaft bearings, making the unit able to withstand significantly higher radial loading. Mechanical drives have internal spaces that have void spaces where residues can be deposited.


Idler Gears 


Idler gear wheel placed between two other gears to transmit motion from one to the other. It does not alter the speed of the output, but it does alter the direction it turns. It is used to ensure that the rotation of two gears is the same. An idler gear is placed between two gears. The idler gear rotates in the opposite direction as the driver gear and the follower gear rotates in the opposite direction of the idler, the same direction of the driver. It is also used to change the spacing between the input and output axes. It does not change the gear ratio between the input and output gears. All the gears and wheels that turn inside the treads of a battle tank are all idler gears that transfer power from the input gear to the output gear to move the tread and move the tank forward. The power take off mechanism includes a gear train with an input idler gear, a first intermediate idler gear, a second intermediate idler gear and an output gear. The input idler gear receives a rotary input and the first intermediate idler gear meshes with the input gear and the second intermediate idler gear. The output gears transmit rotary power to one of the first and second axles.

Worm Gears




Industrial Gears

We service a wide spectrum of industrial gears including mining, pulp and paper, tunnel boring, compressor drives, steel, automotive, aerospace and many more by providing quality gears. We can provide ground gears up to 95" in diameter and cut gears over 20 feet in diameter. Our diverse capabilities include:

External gears to 240 inches diameter.
Internal gears to 270 inches diameter.
Carburized and external and internal ground gears to AGMA Quality 14.
Spur, helical, and double helical gears.
Bevel Gears.
Ground worms and worm gears.
Large machine shop, including extensive CNC capabilities.


Reduction Gears



We are manufacturers and exporters of worm reduction gear box. Casings are made from fine graded cast iron. Worm are made from nickel alloy steel, case hardened and precision ground surfaces. Worm Wheels rims made from Aluminium, Bronze and Phosphorous Bronze (PB2C) casted on Graded Cast Iron hubs. The worm gears are hobbed with multi start hobs to ensure a high load carrying capacity. All these internals are supported on high quality Ball / Roller Bearings designed for life under Grease / oil splash lubrication. Hardened and ground worm drives are available.

Spur Gears



The company manufactures durable and highly efficient spur gears upto 5000 mm OD 50 Module in Cast Iron & Steel (Single, Double & Multi Starts) for Cranes, Material Handling Equipment, For Cement plants, Sugar plants, Chemical plants and Mineral Processing Plants, Coal Handling Equipment, Steel Rolling Mills & Petrochem sectors. They connect parallel shafts, have involute teeth that are parallel to the shaft and can have internal or external teeth. They cause no external thrust between gears. They are inexpensive to manufacture. They give lower but satisfactory performance. They are used when shaft rotates in the same plane. The main features of spur gears are dedendum, addendum, flank and fillet. Dedendum cylinder is a root from where teeth extend, it extends to the tip called the addendum circle. Flank or the face contacts the meshing gear, the most useful feature if the spur gears. The fillet in the root region is kinetically irrelevant.

Planetary Gears



A gearset in which all of the gears are in one plane, grouped around each other like the planets around the sun. The central gear is called the "sun gear". In mesh with it is a circular grouping of gears, called "planet gears", mounted on a rotating carrier. The planet gears also engage teeth on the inner periphery of the "ring gear". By holding any one of the three gear elements motionless, different ratios can be produced between the other two. Planetary gearsets are common in automatic transmissions.
