We offer an impeccable range of universal joint couplings, with the aid of our cutting edge technology. Prepared from alloy steel with heat treated working parts, our range of universal joint couplings is available with or without finish bore as per customer requirement. Our couplings are appreciated for durability, high tolerance and corrosion resistance.

Specifics:

• Up to 4" shaft size
• 2000 kg Torque
• Available up to 8"

We offer a wide assortment of gear couplings, prepared using optimum quality grades of raw material. Available in fully flexible and half rigid gear couplings, our range conforms to defined industry standards.

Specifications encompass following:

• Available in range of 19 sizes
• Can transmit torque up to 12,00,000 Nm
• Accept diameter up to 1250 mm

Construction

Full gear type LFG Lovejoy Flexible Gear Coupling consists of two identical toothed hubs, tow identical flanged sleeves with internal teeth, a gasket, a set of bolts, nuts and lock washers, lube plugs and two oil gears reataining seals over the hubs.

Nomenclature

• Forged Hubs with external teeth
• Forged sleeves with internal teeth
• Flange Gasket
• Close tolerance connecting botls
• Lubrication Plug

Selection Procedure

• Select an appropriate SERVICE FACTOR from table given below.
• Multiply trie rated running power by the service factor This gives DESIGN POWER at rated speed (rpm)  Convert this to design power at 100 rpm. This is used as a basts tor coupling selection.
• Refer to the rating column and read until the power greater than or equal to the design power al 100 rpm is found. The size of the gear coupling Is given inlhe corresponding first column  Check the max bore capacities. If required bore size is given in the corresponding first column. Check the max. bore capacities. If required bore size is greater than the max. bore of selected coupling size, the go for higher size meet the required bore.
