Walther Flender Gruppe Clamping sets Page 43 Causes of malfunctions Fault Cause Solution Excessive noise levels Misalignment of pulleys Excessive belt tension Overload of drive system Worn timing belt pulley Incorrect pulley profile Rim flange stop face too large Air displacement in hollows Visible belt elongation Reduction of centre distance of axes due to loosening of the shaft bearings or timing belt pulley mounting Pulley wear (outer diameter) Overload of drive system Heat-up and subsequent cooling of drive system Excessive change in the timing belt material (melting, softening) Belt runs off to side Belt runs off the side of the timing belt pulley Excessive wear on side of belt Loosening of rim flanges Misalignment of pulleys, resulting in excessive axial forces Align pulleys Excessive wear on side of belt Incorrect axis parallelism or change in the centre distance of axes due to insufficient strength of bearings and axles Rim flanges defective or not bevelled Damage due to incorrect handling Timing belt too wide Premature tooth wear Initial tension too high or too low Belt runs off over rim flange Incorrect belt profile for timing belt pulley Worn timing belt pulley Timing belt pulley surface too rough Overload Excessive damage due to foreign objects Shearing of belt teeth Not enough teeth meshing Overload of drive system Worn timing belt pulley Incorrect belt profile for timing belt pulley Insufficient belt tension Extreme shock loads Broken belt Timing belt pulley diameter too small Overload of drive system Foreign objects Incorrect handling of timing belt during installation, belt damaged from kinking or bending Abnormal wear of timing belt pulley (outer diameter or tooth flanks) Increased belt tension or overload of drive system Timing belt pulley diameter too small Incorrect profile Foreign objects Cracks in tooth back Temperature too low Temperature too high Aggressive chemicals Increased temperature Initial tension too high or too low Incorrect timing belt profile or timing belt pulley profile Outer diameter too large Vibrations Initial tension too high or too low Loose timing belt pulley Vibrations in the slack side Align pulleys Reduce initial tension Increase belt width Replace timing belt pulley Correct profile Use of standard rim flanges with bending radius Custom profile Reset centre distance of axes and reinforce mounting Replace timing belt pulley Redesign drive system Check thermal expansion coefficient and use other materials, if necessary Reduce temperatures to permissible range Align drive system correctly Align drive system correctly Check axis parallelism and/or increase strength of axles and bearings Align or replace rim flanges Follow procedure in assembly instructions Use timing belt pulleys with correct width Correct initial tension Align timing belt pulley/correct initial tension Use PolyChain® timing belt pulleys Replace timing belt pulley Replace timing belt pulley System must be redesigned Timing belt cover Increase number of pulley teeth or use smaller pitch Increase belt width Replace timing belt pulley Use correct tooth profile Set correct belt tension System must be redesigned Increase pulley diameter or belt power output Use wider timing belt Protective drive cover Comply with installation instructions Reduce initial tension or increase belt width; redesign system, if necessary Use correct timing belt pulleys Use correct drive system Protective drive cover Avoid low temperatures Avoid high temperatures Protective drive cover Set correct initial belt tension Use correct drive system Correct outer diameter Set correct initial belt tension Re-attach timing belt pulleys and mount according to specifications Install a tangential tension pulley
