Mounting variants

Mounting work – Influencing factors and assessment

The amount of work involved in mounting is essentially determined by:

  • the arrangement of the screw mounting and locating surfaces for the guideways and carriages
  • the accessibility of the fixing screws.

Based on these points, the mounting work can be assessed.

The structure, ➤ Figure, is ascending and describes the work according to the following criteria:

  • simple mounting without fitting aids
  • simple mounting with fitting aids
  • demanding, time-consuming mounting with fitting aids
    .

For reasons of time and cost (reduced mounting work) only variants corresponding to

and
should be selected.

For the assessment of mounting work, see table.

Connection to the adjacent construction

The connection between the guidance elements and the adjacent construction influences the effective load carrying capacity. The direction of the forces and moments, the position and arrangement of the locating faces as well as the load carrying capacity and the number of screws must be taken into consideration.

The better supported the guidance system is in relation to the forces occurring, the greater the extent to which the load carrying capacity can be used, ➤ Figure.

ACHTUNG

Locating faces must be provided.

Favourable application of force
FS = lateral force

If no locating faces are present, the maximum lateral load that can be transmitted is dependent on the screw connection between the guideway and adjacent construction, ➤ Figure. This must be taken into consideration in the design process at the customer.

FS = lateral force

Pressure and fixing elements

For guideways and carriages, pressure and fixing elements should be provided, see table.
