Sleeve-Flex can be installed quickly and easily, because there are no bolts, gaskets, covers or seals.
Alignments can be checked with a straight edge placed across the outside of the precision machined flanges.

The teeth of sleeve lock into the teeth of the flanges without clamps or screws, tightening under torque to provide smooth transmission of power. There is no rubbing action of metal against rubber to cause wear.
Couplings are not affected by abrasives, dirt or moisture.

The placement of the hubs of the GEARex all-steel gear coupling can make for a very short shaft distance, regular shaft distance and short shaft distance along with a different mounting position of hubs as per customer requirement. The hubs of the gear coupling can be locked and are connected to the coupling sleeve with threaded joints or interference fit. The construction of the sleeve and hub enables transmission of high amounts of torque.

Features:

• Torque up to 135,000 nm
• Hubs can be turned inside and outside as per customer requirement
• Manufactured to AGMA Standard
• Short design which enables transmission of high torque in space constrained application
• High Power Density

Due to the position of the hubs the all-steel gear coupling GEARex DA has a very short shaft distance dimension.

The hubs of this gear coupling can be axially fastened by thread for setscrews or interference fit.

Adjustments of material of sleeve and hubs allow for the transmission of high torques. Thanks to the cover design the gear coupling can easily be mounted. The spline can be visually inspected by dismounting the cover.

Features

 

• Double-cardanic all-steel gear coupling
• High power density
• High torques up to 2,750,000 Nm with small dimensions
• Sleeve in cover design for easy assembly
• High torques with small dimensions
• Both hubs are turned inside
• Short dimensions
• Application ranges: mechanical engineering, pump drives, compressors and steel mills
• Complying with ATEX (acc. to EU directive 2014/34/EU)
• UKEX compliant (according to UKEX Directive SI 2016:1107)
• Double-cardanic

Product Brochure

A gear coupling is a type of coupling that is often used with high torque or high-power output. Gear couplings are typically able to withstand more torque than universal joints, whereas universal joints produce less vibration. A gear coupling is made up of a two-part hub with internal and external teeth and an external or internal sleeve.

Features:

• Minimum backlash
• High bore capacity (Upto 710mm)
• High power to weight ratio
• Accommodates Parallel, Angular and Axial Misalignment
• Can be used up to 120 degrees Celsius. It can be used in even high temperatures if proper oil and lubrication is used.

Fenner Curved Tooth Flexible Gear Couplings are 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. 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 inter-changeability.

They are made for extensive use in Metal Rolling Mills, Paper Machinery, Cranes, Dredgers, Rubber and Plastic Industries, Cement Plants, Conveyors and Elevators, Compressors, Fans and Blowers, Screens and other general industries.

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.

Misalignment

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.

 

A. RADIAL

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

B. ANGULAR

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.

 

CAUTION :


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.
