For safety or convenience they may need to be installed some distance from the motor Follow the control manufacturer’s instructions to make Angular Alignment Foot Plane To determine proper foot plane: V-Belts Hot Alignment Completing Mechanical Installation Doweling Doweling Inserting Dowel Pins Vibration Alarm Trip Timer Trip (Shutdown) Setting (1) Operation Initial Start Oil Circulating Systems For motors with oil circulating systems, proceed as follows before startup; 1.Fill motor reservoirs to normal level (see motor outline drawing) Trouble Shooting TROUBLE POSSIBLE CAUSES CORRECTION Page Maintenance Preventive Maintenance Maintenance Checklist Inspection Antifriction Bearing 1.Remove the parting bolts at the horizontal split Remove the bolts at the outer circumference of the upper half of the 3.Pull the upper bracket away from the face of the frame and remove bracket Sleeve Bearing - 1120 Frames 3.Air deflectors on sleeve bearing motors are horizontally split Vibration Most problems can be detected when inspected visually. Check for; 2.Accumulation of dirt on fan or rotor Associated equipment Foundation construction Insulation Resistance 2.3 + 1 = 3.3 (megohms) Drying Insulation 1.A warm air oven 2.Electric strip heaters Bearings Bearing Construction Insulated Bearings Antifriction Bearings Sleeve Bearings Oil Rings Oil Seals The primary purposes of the oil seal are: 1.To prevent the entrance of dirt into the bearing cavity 2.To retain the oil in the bearing cavity 3.To provide pressure regulation in the bearing cavity Sealing Parts Apply sealant as follows: Surfaces shall be clean of dirt, grease, and oil sealant. Use a gap when mating surfaces are together 4. Assemble parts 1.Ring out of round (should be round to 0.062 inch) 2.Fouling on a projection of the bearing bushing 5.Oil too cold or viscous, or oil level too high 6.Shaft not level – oil ring tends to bind Force Feed Lubrication Bearing Replacement For typical antifriction bearing configuration, see Figure The complete A.F.B.M.A 2.Identifying numerals and manufacturer stamped on the bearing Bearing tolerance class, i.e Sleeve Bearing Sleeve Bearing Replacement 500 and 580 Frames (See Figure 5) MAINTENANCE, SEALING PARTS 680 and 800 Frames (See Figure 6) 1120 Frame (See Figure 7) End Float – Sleeve Bearings Page Spare Parts Identification Parts Identification Siemens Industry Page Bearing Housing Bearing Bushing Oil Seal Oil Ring Air Seal Figure 11a.
