TB WOODS WES5 Dura-Flex Element, Polyether Urethane, WE5 Size, 925 lbs.-in. Torque, 7500 rpm

TB Woods WES5 Dura-Flex coupling element is used with the compatible hub to connect 2 shafts for a high-quality power transmission component, providing reliable and efficient performance. They are suitable for application in the agriculture, manufacturing and material handling industries.

Features:

• WES5 Dura-Flex coupling element features polyether urethane construction for exceptional resistance to wear, oil and abrasion, ensuring long-lasting performance.
• It has a maximum angular misalignment capability of 4 degrees, reducing stress & wear on the system and resulting in smoother and more efficient power transmission.
• This Dura-Flex coupling element offers a maximum RPM of 7500 and 925 lb-inch rated torque, ensuring efficient power transmission and preventing overloading or premature failure.
• It can tolerate a maximum parallel misalignment of 1/16 inches, allowing for slight misalignments between the driving & driven components and compensating for minor variations in their positioning.

Frequently Asked Questions:

Q. How to install this TB Woods WES5 Dura-Flex coupling element?

A.

• Thoroughly examine all coupling components and eliminate any protective coatings, lubricants, paint or rust from bores, mating surfaces and fasteners. Ensure that shafts are free from any existing burrs or imperfections.
• Employ keys as necessary and slide one hub onto each shaft. If utilising QD or Taper-Lock hubs, adhere to the instructions provided with the SureGrip or Taper-Lock bushings.
• For spacer couplings utilising high-speed rings, loosely install one ring on each half element.
• Position one-half element on the hubs to determine the appropriate hub spacing. If employing spacer elements with high-speed rings, hold both half elements on the hubs to confirm that the rings do not encounter any interference.
• Securely but lightly fasten hubs to shafts to prevent any movement during alignment procedures.
• Without rotating the coupling, employ a calliper to measure the widest point around the hub. Adjust the calliper to the narrowest point using feeler gauges. Reposition the equipment until this value is minimised.
• Utilising the misalignment value obtained in the previous step, consult the maximum allowable parallel misalignment. Without rotating the shafts, utilise a straight-edge around the hub and determine the maximum offset using feeler gauges. If necessary, readjust the shafts and recheck parallel alignment.
• Tighten fasteners on the motor and drive equipment according to the manufacturer's specifications. Recheck both parallel and angular alignments.
• Once the parallel and angular alignment values fall within the service ratings, ensure that all set screws, cap screws and other fasteners are securely tightened as specified. Recheck both parallel and angular alignment after tightening.
• Install the coupling guard as per relevant safety regulations.
• Periodically inspect the alignment, as settling can often cause changes in equipment position.

Q. How to determine the proper size of TB Woods WES5 Dura-Flex coupling element?

A.

• Determine the type of prime mover being used, such as an electric motor, internal combustion engine or another power source. This classification is crucial in selecting the appropriate coupling for the application.
• Analyze the specific load characteristics of the driven equipment, including factors like starting torque, speed fluctuations, shock loads, and other relevant parameters. Additionally, consider the service factor, which accounts for the application's duty cycle and any intermittent or peak loads.
• Based on the prime mover's power output and the load requirements, calculate the design horsepower or design torque needed for the coupling.
• With the design horsepower or torque determined, select an appropriate coupling that can handle the specified requirements. Consider the coupling type, size and specific features that align with the application's demands.
