LZL Vane motor/gear unit combinations Combined with helical gear units, type LZL vane air motors can be used over a very wide torque and speed range. Models are nominally available with gear ratios that range from 5:1 to 240:1, corresponding to a speed range of 500 to 18 r/min and an output torque of up to 2500 Nm at max output. Helical gear units type BG. Helical gear units are available in 2, 3, or 4-stage configurations. They deliver high efficiency levels and are available in wide choice of ratios, Figure 4. Shaft loading Figure 4 The maximum allowable radial load on the output shaft of each gear unit, at the half way point on the shaft can be obtained from the data tables for each model. The maximum permitted axial load is 20% of the table value for radial load if full permitted radial load is occurring. If there is no radial load the maximum permissible axial load is 50 % of the table value for radial force. 5 6 AT L A S C O P C O A I R M O T O R S Calculating sprocket or gearwheel dimensions If it is intended to fit a sprocket, gearwheel or pulley onto the output shaft, the radial load generated when running must be within the permitted level. The following formula is used to calculate the minimum diameter of these components, to ensure the radial load does not exceed this limit. Dmin = 2 x M x kt [m] F where M = load torque in Nm F = permitted radial force halfway along the shaft extension kt = 1.0 for sprocket 1.3 for gear wheel 1.5 for pulley Operating speed To avoid damage to seals the gear units should not be run continuously above 4200 rpm. Mounting There are two options of mounting arrangement: Foot or Flange as illustrated in fig.5. 1. Foot Temperature 2. Flange Figure 5 The gear units can operate within an ambient temperature range of –20°C and +40°C. If it is required to use a gear unit outside these temperature limits please consult with your local Atlas Copco representative.
Mounting position/ordering procedure. Depending on the mounting position of the motor with gear the amount of oil in the gear unit varies. Therefore the mounting position must be specified together with ordering number for motor/gear unit. The mounting position is specified with the 10 digit numbers according to description below. The alphanumeric numbers B3, B5 etc. are referred to in the product information enclosed at delivery. Position number: 8990 0020 01 Position number: 8990 0020 19 B3 B5 B6 B51 Position number: 8990 0020 27 B7 B53 Position number: 8990 0020 43 V5 V1 Position number: 8990 0020 35 B8 B52 Position number: Please contact your Atlas Copco representative.
