Nylon Gear Coupling

Nylon gear couplings/ GE gear couplings/NL Nylon couplings/ 

We have with us a wide range of Gear Couplings, which include the standard gear couplings and the steel gear couplings. Available in metal seal and o-ring designs, these couplings are provided with advanced features like crowned and barreled teeth with tooth tip piloting, fitted bolts and forged steel components. Owing to their quality features, these gear couplings are confirmed to the gear coupling specification number

We are well known Gear Couplings manufacturer and supplier. We offer gear couplings, flexible gear couplings etc., which all are unmatched example of modern engineering. Under the misalignment condition of two shafts of the equipment, the teeth contact in case of straight cut hub will be as minimum-as shown. Under heavy loads the ends of the hub teeth will get damaged resulting in the excessive play between hub and sleeve, and, therefore, the reduction in life of coupling.

A gear coupling is a mechanical device for transmitting torque between two shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle.

Each joint consists of a 1:1 gear ratio internal/external gear pair. The tooth flanks and outer diameter of the external gear are crowned to allow for angular displacement between the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are called gears because of the relatively large size of the teeth.

Gear couplings and universal joints are used in similar applications. Gear couplings have higher torque densities than universal joints designed to fit a given space while universal joints induce lower vibrations. The limit on torque density in universal joints is due to the limited cross sections of the cross and yoke. The gear teeth in a gear coupling have high backlash to allow for angular misalignment. The excess backlash can contribute to vibration.

Gear couplings are generally limited to angular misalignments, i.e., the angle of the spindle relative to the axes of the connected shafts, of 4-5°. Universal joints are capable of higher misalignments.

Gear Coupling follows the international standards of AGMA and JIS ,which easily allows to replace with major industrial products .Our Gear coupling compensate angular misalignment ,parallel misalignment and end float .The fully crowned hub teeth provide minimum loading stress , and ensure longer life.

Characteristic

1)      High torque, small size, long life and very little loss of transmitting power.

2)      The concave-convex flange design allows easy assembly and the high quality gasket prevent leakage of lubricant.

3)      Gear Coupling permits parallel, angular misalignments and end floating by crown gear teeth.

 Application:

a)       Heavy load, but compact design coupling.

b)      Highs speed up to 5000 rpm(Depending on size ,refer to the data)

c)      Low speed, but high starting torque.

d)      End float application

e)       Spacer required ,due to longer distance between shaft ends

f)       Low load and light weight application is not recommendable.
