Frame Design January 11, 2013UL Vibration Test Apparatus11 Advantages: Allows for a single technician to mount the luminaire Extra support of U-channel decrease vibration of system Rubber pads in-between supporting beams help in dampening the system More space efficient than current design Approximately 44” X 34” footprint
Lubrication Drive Shaft Bearings: Double sealed flange mount bearings with easy access grease zerk fittings. Linear Bearings: Double sealed closed bearings with easy access grease zerk fittings. Crank Arm Bearings: Double Sealed roller bearings pre-packed with grease. Easy access for lubrication by taking off Polycarbonate cover. January 11, 2013UL Vibration Test Apparatus12
Test Plan Test the deflection of the pipe Dial gauge Measure required torque using torque wrench Flanged collar mechanism January 11, 2013UL Vibration Test Apparatus13
-Brinkman Lab Machining: $90 per hour -Only part of the frame may be developed for test purposes -Unexpected tooling costs that may arise -Need for remaking parts (we are not expert machinists)
