PRODUCT SAFETY INFORMATION Product Safety Information General - The following information is important in ensuring safety. It must be brought to the attention of personnel involved in the selection of the equipment, those responsible for the design of the machinery in which it is to be incorporated and those involved in its installation, use and maintenance. The equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power transmission equipment proper precautions must be taken as indicated in the following paragraphs, to ensure safety....

INSTALLATION & MAINTENANCE GEAR COUPLING WITH NYLON SLEEVE

NYLICON COUPLING INSTALLATION OF NYLICON GEAR TYPE FLEXIBLE COUPLINGS Errors of alignment fall into categories of angularity and eccentricity, or a combination of both. While the NYLICON gear type flexible coupling compensates for a certain amount of misalignment, its life is greatly Increased if any errors present are reduced as much as possible. It is important, therefore to check the coupling for alignment with the setting gauge supplied before tightening the grub screws in the two hubs on their respective shafts. The gauge should be placed on the coupling as shown above. Check for...

INSTALLATION & MAINTENANCE ELFLEX COUPLINGS FLEXIBLE PIN AND BUSH COUPLING

1.0.1 Inspect the coupling components and remove any protective coatings, ensure all coupling parts and mating shafts are clean and free of oil or grease. 1.0.2 Check the key fit in both shafts and hubs, and fit the keys into the shafts 1.0.3 Install each coupling half on its shaft, the half containing the rubber elements should be mounted on the driven shaft, the hubs should positioned so that the coupling face is flush with the shaft end Note! With press fits it is recommended to apply an appropriate lubricant to the hub bores and shafts, The hubs may be heated (max 120° C) to install...

ELFLEX PIN AND BUSH FLEXIBLE COUPLING REMOVAL 1.1.9 Slacken all screws by several turns. Remove one (size 12 to 13, remove two) and insert it (them) into the jacking off holes shown thus in the diagram, after oiling thread and point of grub screws or thread and under head of cap screws. 1.1.10 Tighten the screw(s) until the bush is loosened in the hub and the assembly is free on the shaft. 1.1.11 Remove the assembly from the shaft. Check shaft alignment as follows:- Errors of alignment fall into categories of angularity (see figure 1) and eccentricity (See figure 2), or a combination of...

CONE RING FLEXIBLE COUPLING 4.0 4.1 RUBBER BUSH INSPECTION Check the condition of the rubber bushes periodically (every 6 months) for wear. If the outside diameter of the bushes is worn down more than 5% compared to the pin bore diameter, then the pin and bush assembles should be changed. With the pins removed an alignment check in accordance with Section 2.0 should be carried out. New pin and bush assemblies shall be fitted back into the coupling as detailed in section 3.0

INSTALLATION & MAINTENANCE ELIGN COUPLINGS GEAR TYPE COUPLINGS

Type ER Single Engagement 1.1 Inspect the coupling components and remove any protective coatings. Ensure all coupling parts and mating shafts are clean and free of oil or grease. 1.2 Check that the keys fit correctly into both shafts and hubs (1) or (3) Coat each key with a grease resisting sealing compound (to prevent leakage of grease through the keyway) and fit the keys into the shafts 1.3 Apply a light coat of grease to the O-rings (8) and insert O-rings into grooves (X) in sleeves (2) on ES type couplings insert the O-rings into end caps (2a) 1.4 Place sleeves (2) over shaft ends, on...

ELIGN GEAR COUPLING 1.0 HUB ASSEMBLY - cont.. 1.6 Coat the hub (1) & sleeve (2) gearing with coupling grease (see appendix ??) and place the sleeve over the hub 1.7 Install the machinery to be connected and set the gap (F) between shafts. Note! The gap can vary dependant on coupling size and type. See the table 3 or an approved drawing for the correct gap, - if in doubt pease contact our engineers. 1.8 Adjust machinery for acceptable shaft alignment as per section 2.0. Note! Use metal shim strips under machinery feet as packing to achieve adjustments. 1.9 Slide sleeve over the hub into...
