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.

Advantages of EPT gear coupling

1. Lowest price based on large scale production.

2. High and stable quality level.

3. Widely used in various mechanical and hydraulic fields.

4. Compensation for axial. radial and angular misalignment.

5. Convenient axial plugging assembly.

6. No brittlement at low temperature.

7. Good slippery and frictional properties.

8. Resistance to chemical corrosion.

9. Rich experience working with big companies in this field.

Design advantages

The Flexible Coupling method of connecting rotating shafts is a vital and necessary technique. Large massive shafting. loosely mounted in sleeve bearings and merely joined together by rigidly bolted flanges. cannot provide efficient mechanical power transmission. Especially today. as machine designers and builders demand higher speeds. higher torques. and higher misalignment capacities. the need for “flexibly connecting” this equipment becomes apparent.

A flexible coupling is necessary since it is practically impossible to achieve and maintain perfect alignment of coupled rotating shafts. During initial assembly and installation. precise alignment of the shaft axes is not only difficult to achieve but in many cases it is economically unfeasible. During operation. alignment is even more difficult to maintain. Shaft misalignment – caused by uneven bearing wear. flexure of structural members. settling of foundations. thermal expansion. shaft deflection and other factors – is an operating certainty. Because these factors are extremely difficult to control. a flexible coupling serves as an ideal answer to compensate or minimize the effects of unavoidable misalignment and end movement of coupled shafts.

 

A flexible coupling must provide three basic functions:

1. Physically couple together two rotating shafts for efficient transmission of mechanical power. transferring the torque of one shaft to the other. directly and with constant velocity.

2. Compensate for all types of misalignment between rotating. connected shafts without inducing abnormal stresses and loads on connected equipment. and without tangible loss of power.

3. Compensate for end or axial movement of the coupled shafts. preventing either shaft from exerting excessive thrust on the other and allowing each to rotate in its normal position.
