EAAuxiliaryType EA One-way Auxiliary Branch-off Spiral Bevel GearboxONE-WAY AUXILIARYAvailable RatiosType EA gearbox is available in 1:1and 10 speed-reducing ratios:1.25:1 3:11.5:1 3.5:11.75:1 4:12:1 5:12.5:1 6:1and 4 speed-increasing ratios:1:1.25 1:1.751:1.5 1:2One input and up to three output shafts in one plane.Engineering note: d 1 and d 5 operate at the same speed.Internal Gear ArrangementsSchematic:d 1d 2DimensionsThe dimensions for the 8 sizes of speed-reducing ratiosare the same as those for STANDARD speed-reducinggearboxes. See the table on page 11.The dimensions for 8 sizes of speed-increasing ratiosare the same as those for STANDARD speed-increasinggearboxes. See the table on page 13.14
Monitoring the Oil LevelAuxiliary pinion EA style gearboxes may requirespecial oil level monitoring. When a one-way EAauxiliary gearbox is mounted vertically, the normaloil level sight-glass is used to monitor the oil level.When the gearbox is mounted horizontally, thenormal sight-glass can no longer be used. An externalsight-glass must be installed. The schematic at rightindicates the various positions available. This isTandler special design S-545. When ordering agearbox with this feature, please specify this specialdesign number and position of the sight-glass:(example: A1 EA-III 1:1 S-545-A).Also see page 32 for additional lubricationinformation, or consult your DieQua representative.Vertical Shaft ApplicationsGearboxes mounted with a shaft in a verticalposition will require special lubrication options. Thebearings supporting the upper portion of the verticalshaft generally do not receive sufficient quantities ofoil for proper lubrication and cooling. Severaloptions exist:EAONE-WAY AUXILIARY1. For vertical pinions S515 d1:The pinion is supported by two preloaded angularcontact ball bearings. The lower bearing isreplaced by a sealed bearing, and the pinion cavityis filled with grease.2. For vertical shafts S515 d2:The ball bearing supporting the upper portion ofthe vertical shaft is replaced with a permanentlylubricated sealed ball bearing.Radial Load CapacitiesSizei = 1:2 to 3:1 i = 3.5:1 to 6:1 i = 1:2 to 3:1 i = 3.5:1 to 6:1Sized 1 = d 5 d 2 d 1 = d 5 d 2 d 1 = d 5 d 2 d 1 = d 5 d 2STD 00STD 01STD A1STD B1300 N500 N1200 N1750 N320 N1000 N2500 N3500 N--450 N1000 N1500 N--1000 N2500 N3500 NSTD C1STD D1STD E1STD F13000 N3500 N4000 N6000 N4500 N7000 N8500 N10,000 N2000 N2400 N2800 N3500 N4500 N7000 N8500 N10,000 NThe figures in the table above are provided for reference only.
