L I N E A R P O S I T I O N E R SLinear Motion Terminology: Linear Positioner PrecisionBacklashThe clearance between elements in a drive train or leadscrew assembly which produces a mechanical “dead band”or “dead space” when changing directions, is known as thebacklash in a system.In most mechanical systems, some degree of backlash isnecessary to reduce friction and wear. In a Kollmorgen LinearPositioner System, system backlash will typically be 0.010– 0.015 inches. Usually 0.006 – 0.008” is attributed to the ballscrew/ lead screw assembly. For ballscrews this will remainconstant throughout the life of a cylinder, while for leadscrews it will increase with wear.Reducing the Effects of Backlash1. Approach a stop position from the same direction.2. Apply a constant linear force on the cylinder thrust tube orcarriage. This is done automatically for cylinders used invertical orientations with a backdriving load.3. For programmable positioning devices it is possible toprogram out backlash by specifying a small incrementalmove (enough to take out the backlash) prior to makingyour normal moves in a particular direction.4. Use a preloaded nut on a ballscrew to counteract thebacklash. Contact Kollmorgen about the precision groundscrew option which reduces backlash in the drive nut.5. An inline positioner with the motor directly coupled tothe ballscrew has less backlash than parallel or reverseparallel units which utilize a gear train or drive belt/pulley.Primary Sources of Backlash1.

Linear Motion Terminology: Critical Speed and Column LoadingCritical SpeedAll ballscrew systems have a rotationalspeed limit where harmonic vibrationsoccur. With Kollmorgen cylinders,this limit is a function of unsupportedballscrew length. Operation beyond thiscritical speed will cause the ballscrew tovibrate (whip violently) eventually bendingor warping the screw.Column StrengthAll ballscrews have a maximum columnloading limit which causes the screwto compress as load increases. InKollmorgen cylinders this limit is afunction of unsupported lead screwlength. Exceeding this limit will causethe ballscrew to buckle and becomepermanently damaged.Determining the LimitsCritical Speed and Column Loadinginformation for each screw type (i.e. 2B,5A, 8A, 5B …) can be found at the bottomof each “Performance” page in theparticular linear positioner’s section.SPEEDEC4-AKM52G-nnn-15-10BCompression (column) LoadTORQUE - N-m, lb-in0.0 3.8 7.6 11.4 15.1 18.9 22.70.0mm/s in/s33.5 67.0 100.6 134.1 167.6 201.1413 16.3330 13.0248165830.09.86.53.30.00 520 1040 1560 2080 2600 31200 2313 4626 6939 9252 11565 13878THRUST - lb, NEC4-AKM52G-15-10BL37152972222914867430MOTORRPMColumnLoad LimitThrustLoadColumnSpeed LimitLinear PositionersL I N E A R P O S I T I O N E R SExampleFind the Column Load and Critical Speedlimits for an EC4-10B, 42 inch strokeelectric cylinder.
