Shaft Mounted Gear Box Shaft Mounted Gear Boxes are manufactured in standards 5:1, 12.5:1 & 22:1 and also in customized ratios based on requirements. The gear box shaft dimensions are interchangeable with reputed Indian and European manufacturers. Gears from case hardened alloy steel and O/P shaft from medium carbon steel or with or without key are housed in graded C.I housing. Flange motors to IEC/CFMA frames can be accommodated as integral unit when required. |

Helical Gear Box The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement. His gradual engagement makes helical gears operate much more smoothly and quietly than spur gears. For this reason, helical gears are used in almost all car transmissions. Because of the angle of the teeth on helical gears, they create a thrust load on the gear when they mesh. Devices that use helical gears have bearings that can support this thrust load. One interesting thing about helical gears is that if the angles of the gear teeth are correct, they can be mounted on perpendicular shafts, adjusting the rotation angle by 90 degrees.

Spur Gear Spur gears are the most common type of gear. The teeth on spur gears are 90° to the side, or face, of the gear. This requires that spur gears run parallel to one another. Spur gears can be arranged in long trains to meet required ratio reductions as well as maintained required size constrictions. The larger of two gears are typically called the gear, with the smaller one being a pinion. Manufacture Capacity

| Helical Gears What are Helical Gears? Helical gears offer a refinement over spur gears. The teeth are cut at an angle, allowing for more gradual, hence smoother meshing between gear wheels, eliminating the whine characteristic of straight-cut gears. The advantage of helical gears is an increased load capacity due to the extended face width over spur gears. the use of helical gears is indicated when the application involves high speeds, large power transmission, or where noise abatement is important. The speed is considered to be high when the pitch line velocity (i.e. circumferential velocity) exceeds 5000 ft/min or the rotational speed of the pinion (i.e. smaller gear) exceeds 3600 rpm. Helical gears may also be ran at 90 degrees to one another by using gears with the same helix angle. Manufacture capacity

Bevel Gears What are Bevel Gears? Where two axles cross at point and engage by means of a pair of conical gears, the gears themselves are referred to as bevel gears [1]. These gears enable a change in the axes of rotation of the respective shafts, commonly 90°. A set of four bevel gears in a square make a differential gear, which can transmit power to two axles spinning at different speeds, such as those on a cornering automobile. Manufacture capacity Diameter = 20 mm to 800 mm Module = .40 to 30 Module Face Width = 200 mm |

| Internal Gear What are Internal Gears? A gear with teeth on the inner cylindrical surface. The teeth can be either spur or helical. In an involute-form, internal gear teeth have a concave rather convex shape with a thicker base than an equivalent external gear. This not only gives it greater tooth strength but due to a lower sliding velocity along the tooth profile, also makes them quieter. Manufacture capacity Max. Internal Dia. = 450 mm (Ext. Dia - 600 mm) Module up to 6 Module Face width = 120 mm | |||||||||||||||||||

Worms & Worm Wheels What are Worm & Worm Gears? If the axles are skewed, that is, non-intersecting, then a worm gear can be used. This is a gear that resembles a screw, with parallel helical teeth, and mates with a normal spur gear. Worm gears are used when large gear reductions are needed. It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater. Manufacture capacity Worm Wheel Diameter up to 1500 mm Module up to 20 Worm Diameter up to 300 mm Module = 1 to 20 Minimum CD of Worm & Worm Wheel = 28 mm by Tangential Method. |

| Pinion What are Racks & Pinions? Torque can be converted to linear force by a rack and pinion. The pinion is a spur gear, and meshes with a toothed bar or rod that can be thought of as a sector gear with an infinitely large radius of curvature.
