  • Page 60: Start-Up

    Start-up Start-up Risk of personal injury or damage to other system components caused by rapid linear motion of the transport carrier, caused by thrown loads. Only authorised specialist personnel may start up the linear unit. Risk of crushing if the transport carrier is moved in the wrong direction. If the directions of rotation of the drive (motor or gearbox) and the carriage drive (spindle or timing belt) do not match, the mounted transport carrier may move in the wrong direction.

  • Page 61: Operation

    Operation Operation Risk of damage from harmful environmental influences! Operate the linear unit only under the ambient conditions approved by the manufacturers. Ambient conditions Operate the linear unit only within the permissible temperature range of 0 … 80 °C. If the linear unit is operated in moist, abrasive medium, foreign bodies may penetrate it.

    Start-up Start-up Risk of personal injury or damage to other system components caused by rapid linear motion of the transport carrier, caused by thrown loads. Only authorised specialist personnel may start up the linear unit. Risk of crushing if the transport carrier is moved in the wrong direction. If the directions of rotation of the drive (motor or gearbox) and the carriage drive (spindle or timing belt) do not match, the mounted transport carrier may move in the wrong direction.

  • Page 98: Operation

    Operation Operation Risk of damage from harmful environmental influences! Operate the linear unit only under the ambient conditions approved by the manufacturers. Ambient conditions Operate the linear unit only within the permissible temperature range of 0 … 80 °C. If the linear unit is operated in moist, abrasive medium, foreign bodies may penetrate it.

  • Page 99: 10 Maintenance

    Maintenance 10 Maintenance • All installed ball bearings are sealed and maintenance-free. • Remove excessive dust and dirt from the cover band and other components of the linear unit on a regular basis. • The timing belt is maintenance-free. If the timing belt rips or is stretched beyond its elastic range, replace it.
  • Page 100 Maintenance Lubrication points on linear units Figure 9: Possible lubrication points (1) on the carriage The categories and positions of lubrication point depend on the model of linear unit. The categories of lubrication point are identified by the markings S, F, O on the unit. There is a separate lubrication schedule for each lubrication point category.
  • Page 101 Maintenance Schedule for lubrication point F (for linear guide) Carriage size Lubrication interval Grease type Grease quantity [cm³] per carriage 15 with ball chain approx. 0.4 Greases to DIN 51825- KPE1R-20, e.g. Klüberplex 20 with ball chain approx. 0.6 BE 31-102 approx.

    Maintenance 10.2 Replacing the timing belt To preserve the optimum running of the linear unit and prevent it from being damaged during operation, take care that no foreign bodies penetrate the base profile or other linear unit components during installation and assembly. Do not damage the standard parts (screws, pins, etc.) or the cover band and its elements;...
  • Page 104 Maintenance Procedure Dismantle the drive unit (motor, gearbox). Loosen the lubricating nipples: − On Beta 60 to 80 Unscrew all screw-fit lubricating nipples (a) about 2 turns so as not to damage the sealing faces. − On Beta 60 to 80 Remove all conical lubricating nipples or the external lubrication ports and unscrew the lubricating adapters (a)
  • Page 105 Maintenance Push the left-hand end of the timing belt into the bottom slot on the driven bearing casing until the pulley engages. Rotate the drive shaft by hand and push the timing belt out through the top slot in the bearing. Secure the timing belt holders at the timing belt ends.
  • Page 106 Maintenance Replace the bands indicating the safety zones at the right and left ends of the linear unit as necessary. Only for linear units with cover bands above the timing belt: To ensure the cover band engages safely in its guideway, slowly move the carriage along its entire travel distance by hand.

    Maintenance 10.3 Replacing cover bands To preserve the optimum running of the linear unit and prevent it from being damaged during operation, take care that no foreign bodies penetrate the base profile or other linear unit components during installation and assembly. Do not damage the standard parts (screws, pins, etc.) or the dismantled components;...

  • Page 109 Maintenance Stretch the cover band and fix it by the clamp fitting at the other end. Make sure the O-rings are fitted on the lubricating apertures on the underside of the carriage and refit the carriage in the correct position. To check that the carriage is correctly installed, run it slowly from one end of the linear unit to the other, ensuring the cover band is held all the time in its guideway.
