Rathi couplings

Rathi Transpower Pvt Ltd, is part of the family owned Rathi Group Pune. Our expertise lies in designing and manufacturing flexible couplings for exacting power transmission applications.

Our manufacturing facility boasts of broad spectrum of machining and testing equipment and our processes have continually improved over time. Our facilities are certified to ISO 9001 since 1993.

Few manufacturers globally can offer such a vast variety of standard range of couplings, readily available through our global distribution system.

Our extensive project management expertise and our pursuit of synergies are the key for providing the highest standards for our customers.

Couplings are regularly overlooked until a task is nearing its end. With time running out, clients regularly buy whatever a supplier has available rather than the best answer for the system.

Understanding the application and requirements for coupling choice enables the user to choose the best coupling solution.

Realizing the application details is a standout amongst the most basic and overlooked factors in proper coupling determination.

There are a larger number of elements to consider than simply the undeniable torque and shaft issues. The picked coupling should fit the majority of the application issues.

Although a few distinctive coupling types might be utilized for a given application, each type can contrast in cost, unpredictability and execution.

While choosing a coupling, first decide the space in which the coupling will be introduced to guarantee the item will fit. Installing and keeping up the coupling is likewise basic.

Some coupling designs permit establishment and maintenance without moving the surrounding gear. These "drop-in/drop-out plans" are regularly utilized on huge, heavy gear for simplicity of maintenance.

A few couplings also require periodic maintenance. Maintenance-free, non-greased up structures are favoured and fit into generally applications.

The selection of couplings accessible to the present engineers can be overwhelming, yet pursue our rules and you will land at the ideal coupling for your specific application.

• Does the coupling give satisfactory misalignment protection?

• Can it transmit the heap torque?

• Do I need pivotal movement or hub solidness?

• Can it support the required speed of revolution?

• Will it fit inside the accessible space envelope?

• Can it work at the assigned encompassing temperature?

• Does it give torsional firmness required to positional precision?

• Does it give electrical disconnection between the poles?

• Will it have the required future?

Dual Purpose of Miniature Couplings: Motion Control and Power Transmission

The use of miniature couplings for FA is divided into two groups. The first is for "Motion Control", which means to control the movement of systems using both the combination of stepping motors or servo-motors with couplings.

The other usage is "Power Transmission", which is used to transmit power to the next component.

For the "Motion Control", the most critical requirement for couplings is "precision", accomplished by high torsional solidness.

It is an obligatory condition to choose from "zero-backlash" coupling types, which don't have any "play" in revolution bearing.

Then again, for "Power Transmission", the key requirement for couplings is "quality", which can accept and transmit high torque.

Type of miniature coupling used for "Motion Control"

Over a decade ago, Disk-type coupling, with all metal structure, was highly recommended because of its high torsional stiffness. However, because of dramatic improvements in motor performances, now the best coupling to use is High-Gain Rubber type coupling.

By the combination of high vibration absorption capability and the optimum torsional stiffness, Rubber type couplings avoid the co-vibration of the system and realize the highest performance of the motor.

In the event that you would prefer not to enable any misalignment and need to connect two shafts with high coaxiality, at that point rigid coupling is the most appropriate gratitude to its superior precision.
