Rotex jaw type couplings are characterised by small dimensions, light weight and low mass moments of inertia yet transmit high torques. The running quality and service life of the coupling are improved by accurate all-over machining. Their application is ideal for transmitting torque while damping torsional vibrations and absorbing shocks produced by the uneven operation of certain prime movers. Rotex are torsionally flexible and designed for positive torque transmission, and they are fail-safe. Operational vibrations and shocks are efficiently dampened and reduced, and two congruent coupling halves with concave claws on the inside are peripherally offset in relation to one another by half a pitch. They are designed to enable an involute spider to be located between them. These couplings are capable of compensating for axial, radial and angular displacements of the shafts that are connected. The maximum torsion angle amounts to 5°, and they can be fitted both horizontally or vertically. The flexible teeth of rotex products are subject to pressure only, and this gives the advantage of the individual teeth being ability to withstand considerably higher loads. The elastomer parts show deformation with excessive loads and speeds, so sufficient space for expansion should be given.

Muff Couplings are long cylindrical coupling bored and keyed to fit over both shafts. These are split axially and clamped over both shafts with recessed bolts.

Muff couplings consist of a hollow cylinder whose inner diameter is the same as that of the shaft. These are fitted over the ends of the two shafts by means of a gib-head key. The power is transmitted from one shaft to the other shaft by means of a key and a sleeve. It is, therefore, necessary that all the elements must be strong enough to transmit the torque. Muff couplings are the simplest type of rigid coupling for transmitting high torques at high speeds where misalignment is neither present nor desired.

Our muff couplings are made from the best quality materials such as cast iron, stainless steel, alloy steel and many more materials and are available in various sizes. We also customize muff couplings as per our clients' requirements and specifications.

Fenner Curved Tooth Flexible Gear Coupling is the result of many years of experience in the field of Mechanical Power Transmission. These Gear Couplings are distinguished by their mechanical flexibility and compensation of Angular, Parallel and Axial misalignments of the connected shafts. They are made for extensive use in Metal Rolling Mills, Paper Machinery, Crane, Dredgers, Rubber and Plastic Industries, Cement Plants, Conveyors and Elevators, Compressors, Fans, and Blowers,
Screens and other general industries. Flexible Gear Couplings basically consist of two hubs, with crowned external teeth and two outer sleeves with internal spur teeth.

Gear Hubs and the outer sleeves are manufactured from carbon steel and are hardened to the required degree. They are machined to fine tolerances for proper meshing of the gears as well as for interchangeability.

A Nuteck Gear Coupling is a mechanical device for transmitting torque between two shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle.

Each joint consists of a 1:1 gear ratio internal/external gear pair. The tooth flanks and the outer diameter of the external gear are crowned to allow for angular displacement between the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are called gears because of the relatively large size of the teeth.

Gear couplings and universal joints are used in similar applications. Gear couplings have higher torque densities than universal joints designed to fit a given space while universal joints induce lower vibrations. The limit on torque density in universal joints is due to the limited cross-section of the cross and yoke. The gear teeth in a gear coupling have a high backlash to allow for angular misalignment. The excess backlash can contribute to vibration.

We are offering Rigid Cylindrical Coupling to our clients. The one-piece rigid coupling wraps around the shaft, providing high torsional holding power without damage to the shaft or fretting.

Ruland Rigid Coupling is available in one and two-piece designs, with and without keyways, in aluminum, carbon steel, and stainless steel. A large number of standard sizes are available in straight and step bore combinations to fit shafts ranging in the inch series and in the metric series. Inch to metric conversion couplings is also available by special order. Each rigid coupling is stamped with the Ruland name and the bore sizes for easy identification.

The one-piece rigid coupling wraps around the shaft, providing high torsional holding power without the shaft damage and fretting inherent when set screw style couplings are used. The two-piece rigid coupling has the additional benefit of allowing for disassembly and maintenance without removal of other components. The two-piece design also features opposing hardware for dynamic balancing.

Extra steps are taken in the manufacture of rigid couplings to provide important performance benefits. As one of these steps, the bores of Ruland straight bore rigid shaft couplings are precision honed. Honing of the bores provides several benefits that enhance the overall performance of the rigid coupling. Applications that require strict control of shaft alignment benefit greatly from honing, which assures both bores are collinear. Honing also corrects any residual distortions caused by stresses introduced during the manufacturing process, resulting in around, precisely sized bore. Proper sizing and geometry assure a large percentage of shaft contact and greater torque transmission ability.

Rigid couplings come with Ruland's unique Nypatch® socket head cap screws for increased performance and reliability. Nypatch® is a proprietary process that involves depositing a 360-degree coating of Nylon on several threads of the socket head cap screws. This coating is designed to reduce screw vibration, which can cause the screws to loosen and torque transmission ability to diminish during the course of normal use. The Nylon also provides the necessary dissimilar material to reduce galling of the screw threads in stainless steel rigid couplings.

Double wide shaft collars are an excellent alternative to rigid shaft couplings in applications where space is limited. The double-wide shaft collar has a reduced torque capability compared to the rigid coupling due to its use of a single socket head cap screw per shaft. However, the compact size of the collar reduces inertia making it ideal for motion control applications.

The benefits of using rigid shaft couplings include their economy, high torque capacity, and zero backlashes. Rigid couplings are suitable for applications when misalignment is neither present nor desired, including connecting line-shafting or attaching a motor to a gearbox.

Rigid couplings are increasingly used in precision motion control applications where components are properly aligned. Read the article "Rigid Couplings for Precision Motion Control Applications" to learn how a rigid shaft coupling can be used in servo applications.

We, Ravi Transmission offer a wide range of Torque Limiter that is used as a protective device and limits torque transmitted in a drive system. Our range performs such function by slipping when the torque demand exceeds a preset value because of the shock load. Our range of Torque Limiter automatically re-engages when the overload torque has passed hence no re-setting is required.

We are offering Tsubaki Chain Coupling to our clients. The roller chain coupling is a flexible coupling of amazingly simple construction. It consists of a combination of one coupling chain and a pair of coupling sprockets. Flexible and strong, the U.S. Tsubaki, Inc. roller chain coupling is suitable for a wide range of coupling applications.

Compact and Powerful
Torque is apportioned over the whole roller chain and all sprocket teeth and is held at a point close to the outer diameter of the sprockets. This construction and the superior qualities of U.S. Tsubaki roller chain combine to make a compact and lightweight coupling.

Safe and Smart
The casing, which revolves around the body of the coupling, has an attractive design. And unlike other couplings, there are no dangerous projecting bolts. Connecting and removing the shafts is simply accomplished using a connecting pin.

Easy Alignment
Shafts to be coupled should be aligned as accurately as possible along a straight line. Unfortunately, this proves quite difficult. The chain coupling provides necessary flexibility because the chain and sprocket produce a clearance. In addition to protecting the bearings from overheating and abrasion, it safeguards the machine during use.

• Simple & compact in construction.
• GRADED cast iron is used for the better life of coupling.
• Hub diameters are enlarged for better grip of the large diameter of shafts.

Rigid couplings are used when precise shaft alignment is required; shaft misalignment will affect the coupling's performance as well as its life. These couplings connect rotating members such as shafts so that these couplings secure onto both members and provide transmission of torque and motion. Rigid couplings are used where the axes of the shafts are directly in line. A rigid coupling is suitable for shafts in close alignment or held in alignment without inducing destructive forces in shafts or bearings.

Our rigid couplings are available in one and two-piece designs, with and without key-ways, in aluminum, carbon steel, alloy steel, stainless steel and many more materials. A large number of standard sizes are available in straight and step bore combinations to fit shafts of various dimensions. Extra steps are taken in the manufacturing of our rigid couplings to provide important performance benefits.

These rigid couplings are corrosion and abrasion resistant and fail-safe since stringent quality standards are followed while manufacturing these couplings. Our rigid couplings are also very economical in prices.

Various features of our rigid couplings are as follows:

• Simple and economical

• Maintenance free

• No wear and tear

• Torque limited only by clamping force between coupling and shaft

• Low moment of inertia
