Backlash of cursor:On applying various pressures (shaking by hand) on pos. 30 of thesectional view, running loose (vibrating) should not to be stated.In case of vibrating: -> Adjusting the cursor, chapter 7.3.2.42. Pretension of V-belt:Check the pretension by lifting the belt. It should not be possible to lift thebelt off the section without aid.In that case: -> Tensioning of V-belt, chapter 7.3.1.23. Wear of V-belt:Check the wear of the belt by visual inspection. If there are any signs ofabrasion -> wear.In case of wear: -> Replacing the V-belt, chapter 7.3.1.4_______________________________________________HZR_______________________________________________01.09.00/Goral D:\\DEPO\\GORAL\\DOCU\\HZR\\WART_REP\\ENGL\\7_3E.DOC page 7.3.17.3 Repairs7.3.1 V-belt7.3.1.1 Miscellaneous1. New V-belts are to be unpacked at once. They are to be stored in a dryplace at room temperature.2. Do not bend the belts.3. Pitching of belt and synchronous disks have to match.4. Continuous operational temperatures of maximum 80° C are permitted. Ashort-term increase of temperature up to 120° C can be tolerated.5. The drives are to be protected against dust, dirt, hot water, and steam aswell as acids and lyes.6. Pretension is to be brought in line with the operational load. It must nothowever surpass half the maximum tensile force.(see also table 12).7.3.1.2 TighteningImportant:It means a considerable difference to the achieved pretension if the axis isadjusted unloaded (separate, in horizontal position) or loaded (built-in) Allvalues given in the table refer to the unloaded condition. Deviating fromthese is only permitted on prior consulting of HAUSER.1. Loosen the lock-nut pos. 602. Loosen belt clamping / tensioning component Pos. 50. Loosen locatingscrews pos. 53.3.

This ensures that all guide rolls transport / run.1. For easier working, remove the engine combined with the mechanism pos.72/74 by loosening the clamping screws pos. 76.Important:In case the servo shaft has already been in use, it is recommended toreset the shaft to the start position and to mark this position on the cursorprofile prior to proceeding.With this, checking of the start position required for your programmebecomes easy before restarting operations.2. Dismantle cover plate pos. 41 from casing by removing the screws pos. 42and carefully shift it over the cursor profile as far as it will go.3. Loosen the slotted-head nuts pos. 10 (special tools required, see alsochapter 7.4)4. Adjust pulley by turning the eccentric stud pos. 7 so that it runs with onlyslight pressing.Important:Only slight pressing of the pulleys is permitted as otherwise marksdevelop needlessly which increase an uneven running of the cursorprofile.5. Re-tighten the slotted-head nuts pos. 10 keeping hold of the eccentricstud pos. 7.6. Proceed repeating 4, 5 until all pulleys are running.7. Return the cover plate pos. 41 to the casing and fasten it with screws pos.42.Important:Take care that the wipers are evenly used._______________________________________________HZR_______________________________________________01.09.00/Goral D:\\DEPO\\GORAL\\DOCU\\HZR\\WART_REP\\ENGL\\7_3E.DOC page 7.3.67.3.3 Pulleys7.3.3.1 General Remarks1. The pulleys of the HAUSER linear unit are ball-bearing pulleys withreamless plastic coating.2. The plastic coating of polyamide (PA 6) allows high specific surfacepressing and offers sufficient abrasion resistance.3. With prolonged standstills, the pulleys may flatten out a little whichrecovers completely.4. The ball-bearings used comply with common standards for antifrictionbearings and are self-lubricating. Z-type seals are generally used asseals.5. The pulleys are allowed for an ambient temperature of -40° to 80°.6. With an increased ambient temperature as well as an increased airhumidity, the allowed loads are to be reduced and/or even other materialis to be used.7. With increased air humidity, rust-resistant bearings are to be used due topossible corrosion.Important:Replacing of pulleys should be carried out only by HAUSER staff,wherever possible. For any questions and problems concerning cursorplease refer to chapter 7.3.2._______________________________________________HZR_______________________________________________01.09.00/Goral D:\\DEPO\\GORAL\\DOCU\\HZR\\WART_REP\\ENGL\\7_3E.DOC page 7.3.77.3.3.2 Exchanging fixed pulleys1.
