Frame Design UL Vibration Test Apparatus
Frame Design 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 UL Vibration Test Apparatus
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. UL Vibration Test Apparatus
Test Plan • Test the deflection of the pipe • Dial gauge • Measure required torque using torque wrench • Flanged collar mechanism UL Vibration Test Apparatus
-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)
