Lovejoy Gear CouplingsYes! I am interested
Mechanical Gear CouplingsYes! I am interested

Why Gear Coupling ?

A Gear Coupling is used to join two rotating shafts for efficient transmission of mechanical power. Although the shafts are accurately aligned at the time of installation, it is likely that during the operation the alignment may get disturbed due to setting of foundation, thermal expansion, shaft deflection, wearing out of other parts, improper maintenance and many more reasons. Due to this unavoidable misalignment occurring during the operation a gear coulping provides a better solution to compensate or minimise the effect of misalignment.

The gear Couplings are therefore idealy suited for wide range of application in the entire field of drive technology.


The main function of any Gear coupling is not only to connect two rotating shafts but also to accommodate mis-alignments of the connecting shafts ELIGN Gear coupling accommodates the following three types of misalignment.



When axes of connected shafts are parallel but not in the same straight line


When axes of connected shafts intersect at center point of coupling but not in the same straight line.  

C. COMBINED RADIAL & ANGULAR When the axes of connected shafts do not intersect at point of coupling and are not parallel. 

Besides above three types of misalignment, the ELIGN Gear coupling also permits axial movement of the shaft.



Normally permissible angular mis-alignment of ELIGN gear coupling is 0.75 for each half. However, it does not mean that the misalignment should be permitted to this limit from the initial installation. Since in case of misalignment occurring during operation the Elign gear coupling takes care of it without undue damage to the connected equipment, however the coupling’s life may reduce due to relative motion between hub teeth and housing teeth causing fast wearing out of teeth. It is therefore extremely important to align the interconnecting shafts precisily during initial installation.

Unique Tyre CouplingsYes! I am interested

PX Series couplings are light weight tyre type flexible couplings, has less mechanical losses and are economical. These couplings are easy to installl and need no special toolings. Their inspection can be done without dismentalling them. These couplings need no maintenance or lubrication etc., Standard range covers continuous torque uoto 5.500 NM.



PH Series couplings,in a new sofisticated design, are used to neutralise parellel, axial and angular misallignments upto 8mm., 12mm and 6 degree respectively. It cushions shock loads, absorbs tortional & lateral vibrations.

These couplings consists of punched & slitted tyre firmly bolted with twin hubs and flanges through the hole punched in the tyre, eliminatimg any possibility of the tyre slipping out of the assembly, in all conditions.



UNIQUE Tyre Type Automatic Flexible Cushion Couplings are used to neutralise parellel axial and angular misallignments, Endfloats singaly or in combination and to absorb vibration and cushion shocks. The heart of UNIQUE couplings is a tyre shaped radially split flexible member made of Neoprene / Nitrile / Natural rubber compounds reinforced with Nylon / Rayon cords. Special construction of flexible member allows it to flex at will in all directions with negligible heat build up / powerloss. Thus long life nor only for coupling but also for connected equipment is assured. These couplings are easy to install. Replacement of the flexible member can also be done quickly and easily. Inspeciton of these coupling can also be done without dismentalling them since there is no moving part no lubrication is required.

Fenner Tyre CouplingsYes! I am interested
Fenner Tyre couplings provide all the desirable features of an ideal flexible coupling, including Taper Lock fixing. The Fenner Tyre coupling is a "torsionally elastic" coupling offering versatility to designers and engineers with a choice of flange combinations to suit most applications.

The flanges are available in either F or H version Taper Lock fitting or bored to size B. With the addition of a spacer flange, the coupling can be used to accommodate standard distance between shaft ends and facilitate pump maintenance.

Fenner Tyre couplings can accommodate simultaneous maximum misalignment in all planes without imposing undue loads on adjacent bearings and the excellent shock-absorbing properties of the flexible tyre reduce vibrations and torsional oscillations.

Fenner tyres are available in natural rubber compounds for use in ambient temperatures between -50 C to +50 C. Neoprene rubber compounds are available for use in adverse operating conditions e.g. oil or grease contaminations and can be used in temperatures of - 15O C to + 70O C.

F.R.A.S. tyres are available for use when fire-resistance and antistatic (F.R.A.S.) properties are required.
Industrial Fluid CouplingsYes! I am interested
When the Elecon - Fluid Couplings is filled with oil to the appropriate level and the motor is switched on, oil in the passages between the vanes of the impeller is accelerated radially outwards gaining energy all the time until it reaches the maximum circuit diameter. The oil then passes from the impeller to the runner in which it is forced to move inwards between the vanes and as its radial velocity falls energy is transferred to the runner and output shaft. Because the oil passes directly from the impeller to the runner, (there is no reaction member, as in a torque converter), the efficiency is high, with full load slips of between 2 and 5% being achieved in practice and depending on the application and size selection.
Windage and oil circulation losses are negligible therefore efficiency equals 100% slip %. Should an overload occur the fluid coupling will stall, i.e. slip 100 % at a torque value determined by the initial oil filling level. Thus motor and machine are both protected.
ELECON hydrokinetic constant filling fluid couplings have the following advantages :


The level of performance achieved by Fluid Coupling is governed mainly by the design of its working circuit which includes the shape of the circuit, number of vanes in the circuit, the vanes placement etc. The working circuit developed by Elecon is out of number of years of experience in the field and is vital in the performance of the fluid coupling. Elecon Fluid couplings are very rugged in construction, simple in design and reliable in operation.


When Elecon fluid coupling is connected to the drive system it allows the motor to start practically at no load. This results in reduced starting current enabling quick start and acceleration of the drive motor.


It gives gradual start to driven equipment and thus provides smooth and shockless transmission.


Driving and driven equipments suffer less wear and tear and thus there is reduction in electrical and mechanical maintenance cost.


In case of overload, accidental jamming, the transmission torque is limited by the fluid coupling and thereby providing protection to the electric motor and the connected machine. In case of extended jamming period, fusible plug blow off will empty the fluid coupling thereby disconnecting the output from the input, and protecting both driving and driven equipment. To prevent the loss of oil and to have an additional safety device, thermal trig switch can be provided when demanded in addition to the fusible plug.
