Coupling Installation

COUPLING INFORMATION

COUPLINGS INSTALLATION AND ALIGNMENT

These instructions are intended to help you to install and align the coupling. Covered here will be general information, hub mounting, alignment, assembly, locknut torquing, discpack replacement, and part numbers. The coupling as received, may or may not be assembled.

*If assembled, the locknuts are not torqued.

*If coupling is assembled, remove the bolts that at- tach the hubs to the disc packs. Remove both hubs. Leave the disc packs attached to the center member.

A. Hub Mounting:

1.Clean hub bores and shafts. Remove any nicks or burrs. If bore is tapered, check for good contact pattern. If the bore is straight, measure the bore and shaft diameters to assure proper fit. The key(s) should have a snug side-to-side fit with a small clearance over the top.

NOTE: If the hub position on the shaft does not allow enough room to install the short bolts in the hub after hub mounting, install the bolts and disc pack before mounting hub on shaft.

B. Straight Bore:

1.Install key(s) in the shaft. If the hub is an interfer- ence fit, heat the hub in an oil bath or oven until bore is sufficiently larger than the shaft. 350º F. is usually sufficient. An open flame is not recom- mended. However, if flame heating is necessary, use a very large rose bud tip to give even heat distribution. A thermal heat stick will help deter- mine hub temperature. DO NOT SPOT HEAT THE HUB OR DISTORTION MAY OCCUR. With the hubs expanded, slide it up the shaft to the desired axial position. A pre-set axial stop device can be helpful.

C.Taper Bore:

1.Put the hub on the shaft without key(s) in place. Lightly tap hub up the shaft with a soft hammer. This will assure a metal-to-metal fit between shaft and hub. This is the starting point for the axial draw. Record this position between shaft and hub face with a depth micrometer. Mount a dial indica- tor to read axial hub movement. Set the indicator to “0”. Remove hub and install key(s). Remount hub, drawing it up the shaft to the “0” set point. Continue to advance hub up the taper to the de- sired axial position. Use the indicator as a guide only. A pre-set axial stop device can be helpful. Check the final results with a depth micrometer. The hub may have to be heated in order to reach the desired position on the shaft. DO NOT SPOT HEAT THE HUB OR DISTORTION MAY OCCUR. Install shaft locknut to hold hub in place.

D.Shaft Alignment.

Move equipment into place.

1.Soft Foot. The equipment must sit flat on its base (+/- 0.002 inches). Any soft foot must be corrected now.

2.Axial Spacing. The axial spacing of the shafts should be positioned so that the disc packs (flex- ing elements) are flat when the equipment is running under normal operating conditions. This means there is a minimal amount of waviness in the disc pack when viewed from the side. This

VSS, VSM, VSR specifications

Emerson VSM, VSR, and VSS are advanced technologies designed for process automation and control, often utilized in industrial applications. These systems are part of Emerson's broader portfolio of solutions aimed at enhancing operational efficiency, safety, and reliability.

The Emerson VSM, or Valve Signature Management, focuses on the digital management of valves within a system. One of its main features includes advanced diagnostics that monitor the health and performance of control valves. This technology allows for predictive maintenance, ensuring that valves operate at peak efficiency and reducing the risk of unexpected failures. The VSM utilizes a combination of smart sensors and actuators to gather data, enabling real-time analytics that can enhance decision-making and operational strategies.

On the other hand, VSR, or Valve Status Reporting, enhances visibility into the operational state of valves in real time. This system provides operators with critical updates and alerts related to valve conditions, significantly reducing response times to potential issues. The VSR technology integrates seamlessly with existing control systems, allowing for easier implementation and minimal disruption to ongoing operations. The reporting capabilities feature user-friendly dashboards that present complex data in a straightforward manner, empowering operators to make informed decisions quickly.

The Emerson VSS, or Valve Service Solutions, complements the VSM and VSR by focusing on the maintenance and support of valve systems. This offering includes comprehensive service packages that range from routine maintenance to advanced troubleshooting and repair. The VSS is designed to improve the lifespan of valves through proactive service, ensuring reliability and minimal downtime. Emerson’s trained technicians leverage predictive analytics derived from VSM and VSR data, allowing for timely intervention before issues escalate.

In summary, Emerson’s VSM, VSR, and VSS technologies work together to create a robust ecosystem for valve management in industrial settings. The combination of advanced diagnostics, real-time reporting, and comprehensive service solutions provides operators with a powerful toolkit aimed at optimizing performance and ensuring operational reliability. With these technologies, companies can embrace digital transformation, reduce operational risks, and improve overall process efficiency, leading to a safer and more productive environment. Each component plays a crucial role in empowering industries to meet the challenges of modern automation and maintain competitive advantages in their respective markets.
