Bore Sizing and Recommended Fit, Keyways

9.0Bore Sizing and Recommended Fit

The finish bore size should be based on the actual measured shaft dimen- sion, regardless of whether straight or taper shaft. For keyed shafts, a light interference fit based on a nominal interference rate of 0.0005 inch per inch of shaft diameter is suggested, or refer to published AGMA standards. Do not exceed an interference fit of 0.001 inch/inch of shaft diameter. If other than a light interference fit is desired, consult the published AGMA boring and keyway standards.

For Straight Bores, the rigid hub diameter should be chucked in the bor- ing lathe and dial indicated as shown of Figure 11. For Taper Bores, chuck and indicate as shown on Figure 11. Machine the counterbore and SKIM A REFERENCE DIAMETER on the hub body. Then chuck the hub as shown on Figure 12, and indicate using the reference diameter before final boring. Run-outs should be as near zero as possible. It is essential that the fin- ished bore be concentric with the two indicating surfaces.

10.0Keyways

Keyways should be cut to give a tight fit on the sides and slight clearance over the key. Keyways should not have sharp corners. Refer to published AGMA standards for specific dimensioning of coupling bores and keyways.

11.0General Recommendations

11.1KOP-FLEX KD2 and KD20 disc couplings are designed to operate for extended periods without the need for lubrication or maintenance. Visual inspection of the disc packs is sufficient to assess the operational condition of the coupling.

11.2All machinery should be monitored to detect unusual or changing vi- bration levels. KOP-FLEX KD2 and KD20 couplings, under normal condi- tions, have no wearing parts and will retain their original balance quality. Any change in vibration levels should be investigated and remedial action should be taken immediately.

Important Safety Instructions

Before start-up . . .for reasons of safety and to extend shaft coupling life, follow these requirements.

1.Coupling guards protect personnel.

ALL COUPLINGS MUST BE COVERED WITH A GUARD AS PER OSHA REQUIREMENTS.

2.Recheck alignment after all foundation bolts and mechanical connections are tightened.

3.Make sure all fasteners are properly installed and tightened.

4.Take the time to double check your work.

5.Only authorized KOP-FLEX replacement parts are to be used.

6.Call KOP-FLEX for any clarification or questions.

KD2, KD20 specifications

The Emerson KD20 and KD2 series represent cutting-edge advancements in the realm of process automation and control, particularly for industrial applications. These controllers are designed to provide exceptional performance and versatility, catering to various needs across sectors such as manufacturing, energy, and environmental management.

The Emerson KD20 is engineered for comprehensive data acquisition and control, offering a wide array of features that enhance operational efficiency. One of its standout characteristics is its advanced user interface, which includes a high-resolution display and intuitive navigation. This facilitates easy monitoring and adjustment of parameters in real-time, enabling operators to respond swiftly to changes in process conditions.

In terms of connectivity, the KD20 is equipped with multiple communication protocols, such as Modbus, Profibus, and Ethernet, ensuring seamless integration into existing systems. This flexibility allows the KD20 to communicate effectively with a range of devices, from sensors and actuators to higher-level management systems, fostering a connected and intelligent operational environment.

The KD2, while similar in many aspects, offers more compact dimensions and is tailored for applications where space conservation is critical. It retains the essential features of the KD20 but prioritizes simplicity and efficiency, making it ideal for smaller setups or less complex processes. Its robust construction ensures reliability in demanding environments, withstanding temperature fluctuations and other challenging conditions.

Both models utilize Emerson’s proprietary control algorithms, which incorporate advanced methodologies like PID control and adaptive tuning. These algorithms optimize process control, ensuring consistency and accuracy in output, which is crucial for maintaining product quality and minimizing waste.

Furthermore, the KD series includes advanced diagnostic capabilities that provide valuable insights into system performance. These diagnostic tools help in predictive maintenance by identifying issues before they escalate, thereby reducing downtime and operational costs.

In summary, the Emerson KD20 and KD2 controllers combine sophisticated technology with user-friendly design, presenting powerful solutions for modern industrial automation. Their advanced features, robust construction, and flexible connectivity options make them essential tools for enhancing efficiency, reliability, and overall productivity in a wide array of applications.
