About EPG Group Divisions Formed in 1966, Shen represents an impressive list of internationally respected companies and manufactures under licence to a number of these companies. We also manufacture a range of products and equipment developed and designed by our own engineers. In 1990 an employee owner group was formed and acquired 50% of the company from co-founder Mike Shen . These shareholders span a diverse section of the company and underwrite the efficient function of the EPG Group.

EPG is willing to cooperate sincerely and develop commonly with friends!

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.

How Can You Be Safe When Using PTO Shafts? First, make sure the shaft is shielded. This includes the driveline shield that covers the implement driveline, and the master shield which covers the universal joint and PTO stub shaft on the tractor.Maintain the shield so it can work for you. PTO driveline shields are usually mounted on bearings, so they need to be maintained. always REPLACE the shield when it is damaged or missing.Next, keep a safe distance from it when in use. Keep others away, too. How far? A distance of twice your height is a good start.Allow only those who absolutely must be in the area to be there. Keep all children away!Always pay attention to what is happening. Most PTO victims were caught by surprise.If something goes wrong — stop the machinery; take the PTO out of gear, stop the engine and set the brake. Put the keys in your pocket before working on the machinery.When stopping the machinery for any reason — end of work, lunch, repairs, or communication — take the PTO out of gear, stop the engine and set the brake.Road planers, dredges, and other equipment require power from some sort of engine in order to perform their designed function. Without a power take off, it would be necessary to add a second engine to provide the power necessary to run hydraulic pumps and other driveline attached equipment.
