For drives where torque fluctuations are greater or where the operation is near a serious critical or torsional vibration, a mass elastic study is necessary. To determine an engine drive service factor, first determine the application service factor for motors. Then, use that to find the correct engine service factor in the table below. When the application service factor for motors is greater than 2.0 or where one, two or three cylinder engines are involved, contact jbj Techniques Limi ted technical office telephone: +44 (0)1737 767493 or email: info@jbj.co.uk with complete application details for an engineering review.

20 Standard Coupling Installation Please complete the following steps to install QUICK FLEX couplings. You should have the following pieces before starting the job: » Two hubs. » One insert. » One cover with included hardware. Note: It is critical to identify what style cover you are using, as this will change the hardware included, as well as the installation procedure. A mismatch between the coupling and the applicationmay result in less than optimal performance. There are four types of covers as seen in the diagrambelow. » High-speed cover: QF5 through QF175 use standard snap ring to secure cover in place. QF250 and larger use eight bolts with lock washers. » Low-speed split cover: This cover is free-floating and is located outside the shoulders of the two hubs. All sizes come with four bolts for securing the two halves together around the insert. » High-speed split cover: QF15 through QF250 use eight bolts around the rim to secure the two halves together, QF500 through QF1890 use 16 bolts, and QF3150 and larger use 20 bolts. QF250 and larger use eight bolts with lock washers to secure the cover to one of the hubs. Also available horizontally split. » High-performance split cover: This cover is free-floating and is located on the insert with an internal radial groove. All sizes come with four socket-head cap screws for securing the two halves together around the insert. Installation 1.Check the bore size of the coupling halves and the shafts. Ensure that they are the correct bore size to fit the application. 2.If the coupling does not fit easily, clean and deburr the shafts. 3.Identify cover style: d. If using a high-speed cover, it should be placed on the driven shaft. If space does not permit, then it can be mounted on the drive shaft. If cover uses a snap ring, slide the snap ring down the shaft, then slide the cover onto shaft with the larger opening facing the shaft separation. e. If using a low-speed or high-performance split cover, leave cover aside and continue to step 4. f. If using a high-speed split cover, QF250 and larger, use bolts and washers to secure in place. Slide one half down each shaft before installing hubs. Do not bolt into place until installation is complete. Note: Standard hubs are supplied with a clearance fit and should slide onto the shaft without excessive force. If the hubs have been ordered with interference fit, then industry standards suggest heating the coupling halves to approximately 300° C (572° F) before installing on shafts. If not heated properly, the couplings will not fit on the hub properly.

Table 11. Cover Bolt Tightening Torque 4. Install the first hub. It should be mounted so the end of the shaft is flush with surface “A” as shown in fig. 6. It is acceptable for the shaft to extend past “A” as long as it is not past the teeth shown as “B.” 5. Install the second hub with the insert in place. This will set the hubs at the minimum hub gap (G ) dimension, ensuring proper clearance. For specific Min G and G dimensions see table 12. Min max 6. Tighten both hubs securely to the shafts. 7. Check coupling for misalignment (table 13) and align as necessary. 8. Install the cover: a. High-speed cover: Slide the cover over the hub and insert until fully rested against the shoulder of the hub. QF5 through QF175 use standard snap rings to hold the cover in place. QF250 and larger couplings use eight bolts and washers. Use the included hardware to secure the cover. b. Low-speed or high-performance split cover: Place each half over the insert and secure using the four bolt/ washer/nut hardware combinations supplied. For the high-performance split cover bolt tightening torque ratings, see table 11. c. High-speed split cover: Slide the two cover halves over the hub and insert until faces meet. Install the radial outer bolts used to secure the two halves together. Install the bolts to secure the cover to one hub. Revolutions Per Minute (RPM) andBalance The QUICK FLEX coupling is machined on all surfaces and thus its dynamic balance is good. If the coupling is run at a high speed, it is important that the keys used to attach the hubs are the same length as the hub. The set screws should also be changed to full length to fill the hole. Please refer to table 14 for maximumRPM ratings. Note: Shaft should penetrate to base of teeth and hubs should be set at G . Otherwise, the couplingmay not deliver maximum torque. min 21 Quick Flex Couplings Installation Guide WARNING Failure to observe the following warnings could cause the power transmission product to break and parts to be thrown with sufficient force to cause serious injury or death. Contact with moving parts and/or rotating shafts poses a risk of serious injury. Proper guards in accordance with OSHA and American Society of Mechanical Engineers standards must be installed on all power transmission equipment. Power transmission equipment should not be started if proper guarding is not in place. Observe all required lock out/tag out procedures when servicing power transmission equipment. www.jbj.co.uk/couplings.html #DriveLineHarmony Fig. 6. Proper shaft-to-hub engagement.
