Coupling alignment formula manual

 · Set the dial to zero, and mark the coupling half beside where the button rests. Rotate both shafts by the same amount, i.e., all readings on the dial must be made with the button beside the mark. The dial readings will indicate whether the driver has to be raised, lowered or moved to either side. Image 2 (left). Angular misalignment. suitable alignment fixtures to span the separation and measure the four 90° points. OFFSET ALIGNMENT INSTRUMENT METHOD Note: For maximum coupling life, the Instrument Method of coupling align-ment is recommended. Attach a dial indicator bracket to one hub with dial indicator probe contact-ing the opposite hub’s alignment sur-face. Manual No.: 03/G/IM/10/05/R1. 1 ELECON-HYDROKINETIC FLUID COUPLING TRACTION TYPE: INSTRUCTIONS FOR Fluid Coupling alignment. Kn, using the following formula: From Table 2.b. filling angle for Km of is about 65 degree and from table 3.b the quality of fluid is litres.

Where this information is not avaliable the following calculations will assist in establishing thermal growth. DL = L (c) (DT) Where DL = thermal expansion L = height centerline to base of machine c = coefficient of thermal expansion of material (” for cast iron) DT = change in temp from ambient. So a coupling alignment offset measurement (reverse dial indicator or laser system) of ” at one flexplane, and a flexplane separation of 2” would be a ratio of 4 mils/2” = 2 mils/in. The Alignment Quality Grade chart in the standard shows that at RPM. Coupling Alignment Fundamentals Rexnord, S. Moorland Rd., New Berlin, WI Telephone: Fax: February August

You must have two dial indicators in order to complete this procedure. 1. Attach two dial indicators on the pump coupling half (X): a) Attach one indicator (P). In the case of hot water pump coupling alignment, it is important to observe the pump manufacturer's special instructions relating to thermal deformations. Modern laser alignment equipment also often contains a program that can check for soft foot without undergoing this manual procedure.
