Grid and Spring CouplingsYes! I am interested
Powertech Grid / Spring Couplings give you a combination of advantages of high power rating of a gear coupling and flexibility of elastomer coupling. They are easy to install and simple to maintain. The flexible grids are quickly replaceable without disturbing the connected equipment.
Powertech Grid / Spring Couplings are available in broad range of sizes covering from 0.45 kW to 1307 kW per 100 rpm and bores upto 267mm.

Construction :

A High torque Grid / Spring Coupling basically comprises a grid spring which connects two hubs – one on the driving and the other on the driven shafts – through axially cut grooves around the peripheries of the two hubs. The spring, which is of special design compatible to the required characteristics of the system, form a series of Grid / Spring bridges along the grooves. The grooves are flared to allow the grid members long flexible spans under normal loads as well as better support by the sides of the grooves under over load conditions.
The stiffness of the spring and thus the coupling depends on the length of each flexible span not in the contact with the grooves. Subsequently, the contact length changes with every variation in torque, resulting in change in the stiffness of the coupling at every instant during a vibration cycle. Consequently this produces a powerful detuning action resulting in continuous alteration of the torsional vibration frequency and prevention of a build up of resonance in the system.
The principle of design adopted in Grid / Spring Coupling, makes it capable to accommodate considerable axial, parallel and angular misalignment between a driving machine and a driven machine. Simultaneously, it can absorb considerable overloads due to high torque with consequent reduction in wear and tear on plants and machinery. With the use of Grid / Spring couplings, break-down and down time in any manufacturing unit, will be minimum.
Variable Speed PulleyYes! I am interested

We are engaged in the trading and supplying of the finest quality of Variable Speed Pulley, which is use for conversion of constant speed motor in to a variable speed smoothly and accurately even if machine is in motion. The product is fabricated from superior quality of raw material and available in various sizes to meet the requirements of customer. The product is available with us at competitive prices.



Construction & Working


Pulley disks (A) slide axially along the serrated hub (B) and are forced on to the working flanks of the variable speed belt (C) by special basket shaped springs (D). These special basked shaped springs are located in rotational symmetry on both the disks & provide the required force for efficient power transmission. The connection between the pulley disks & the hub is through serrations. Due to these serrations, mirror allowable surface pressures are maintained. Therefore a very long life is achieved.


Speed Adjus™ent


The drive motor with its variable speed pulley is fitted to the adjustable motor slide base. By adjusting the center distance between the driver and driven shafts, the wide section V- belt is pulled either further in or further out of the spring loaded variable speed pulley and thereby the speed of the fixed pulley. In addition to the motor slide base, speed adjus™ent can be made with motor jacks or jockey pulley.

Swati Motor Slide Base are of flat & solid design. They are robust with perfect parallelogram guide ways, ensuring quite running of Swati Variable Speed Pulleys. To limit the adjus™ent range two end stops are provided. Three Sizes are available in different configurations.

Angular handwheel (u) – The handwheel is fixed at 33° above horizontal plane.


Straight handweel (st) – The handwheel is parallel to the horizontal
