Gear Couplings

Gear Couplings 

We provide precision engineered gear couplings which are applied for transmitting torque and power between two shafts. Gear couplings are used for coupling of motor to fly wheel, fly wheel to gear box and other such uses. We design and manufacture gear couplings as per client specification or as required for the application area.

Technical features :

Gear Material: Forged EN-9 Steel or Forged Low Alloy Steel
Type: Triple crowned double engagement type
Size: Suitable for 150mm PCD Mill to 750mm PCD Mill 01 No. to 20 No.
Lubrication: Allen bolt, forced greased type
Flange Hole: Reamed


Special Features:

• A torsionally rigid, lubricated design that offers high torque capacity
• Capable of taking jerk load
• Rated torque, rated speed, torsional stiffness, and backlash are some of the points considered while designing a gear coupling
• High Tensile fixing bolts
• Teeth of the Gear Coupling are properly heat treated
• All Pitches of the gear coupling are precisely checked

Speed Increaser

Speed Increaser 

We offer speed increaser, which helps in improving machine productivity. They allow the connection of a diesel engine to a drive pump, compressor, or fan, with the input engine speed to be changed to different output speed for the connection. The speed increaser offers greater rigidity and accuracy. The gear speed increaser is equipped with hardened and ground steel gears that minimize noise and vibration.

They require special care in design and manufacturing as they often involve high speeds that may create problems in gear dynamics. We offer these increaser at most competitive prices.
