GEOMETRIC flexible Disc Couplings are torsionally rigid type with zero backlash. Torque is transmitted through pure tension in flexible elements. Flexibility is achieved by flexing elements due to bend between the Drive and Driven bolts and has NO Relative Motion Between Coupling Components hence it requires “NO LUBRICATION”. Reliability of Flexible Disc couplings are very high compared to all other types of couplings include Gear. Disc couplings are maintenance friendly compared to other types. Example for the replacement of Flexible elements in the coupling NO-NEED to disturb the equipment foundation & NO-NEED to remove HUB from the equipment shaft. Low thrust loads and low bending moments on equipment shafts due to misalignment during running. Flexible Disc couplings are Ideal for: STEAM TURBINES, GAS TURBINES, PUMPS, FANS, COMPRESSORS, PAPER MILL Drives etc.

Standard Coupling Design consisting two hubs connected with one spacer and two flexing elements as shown. one hub is mounted on Drive shaft and other is on Driven shaft along with center spacer connected by two flexible elements stacks. These couplings are suitable for PUMP Drives, FAN Drives, PAPER MILL Drives etc.

Generally these designs are having multi spacers and compliance with API 671 standards. The flexible elements are factory assembled and coupling bolts connected to these elements should not be disturbed at site. Gagging screws are provided for compression of flexible element during the time if installation. It consisting of two flanges one is on drive side and other is on driven side. These couplings are dynamically balanced as per the API standard. Hardware which are coming in the coupling are weight balanced to avoid any unbalance due to change the orientation of bolt fixing.

Adaptor designs consisting of two adaptors one is connected to drive equipment flange other is with driven equipment flange. These designs are more popular for high torque transmissions like Steam turbines and Gas turbines & Marine applications. These are transmission unit type and no need to disturb flexible disc pack for dismantling of equipment. Adaptors are designed to suit equipment flange shaft details.

Transmission unit type design having two HUBS one is mounted on Drive shaft other is on driven shaft and connected with factory assembled transmission unit. These couplings are compliance with API 671 standard. These designs are more popular for Petroleum and Petro-Chemical industry include PUMP Drives, Compressor drives, paper M/C drives etc.

Low D.B.S.E & reverse Hub Designs consisting of two HUBS one is connected to drive shaft other is connected to driven shaft having flanges on equipment side. These designs are more suitable for retrofitting of Gear couplings having low DBSE. Major applications are BFP, FANS, MILLS etc.

Shear Pin Couplings are designed to disenguage drive and to the driven-end at a designed torque. Shear Pins will act as mechanical fuse to limit the transmitting torque to safeguard the equipment against Peak torques.
