Design fundamentals / Lubrication / Maintenance

LINE TECH bridge modules

LINE TECH bridge modules with ball screw or toothed belt drive are modular, ready-to-install linear units with drive. Sealed rail guiding elements are em-ployed.Guides and drive are protected from ex-ternal factors (such as dirt and chippings) by a steel strip / the toothed belt.The base profile as well as the lateral profile are made of aluminium alloy and manufactured with the extrusion process.Additional limit switches fitted on the outside, in conjunction with motors and a controller, ensure correct positioning of the carriage and provide protection against overrun.The selected design provides for a high level of performance with the most com-pact dimensions.

Lubrication

LINE TECH bridge modules are lubricated with Microlube GBU Y 131 at the factory. This quality grease offers outstanding properties for the guidance and screw drive elements as well.Greasing should be carried out at regular intervals, depending on the load and area of operation. On an average, re-greasing is required every 500 hours.All roller bearings are greased for life and thus do not require any maintenance. Correct and adequate greasing can substantially prolong the life of bridge modules.

Note: Also follow here the instructions on the grease points, page 102.

Maintenance

LINE TECH bridge modules are main-tenance-free (apart from re-greasing required).

Service temperature

The permissible operating temperature (between 5 and 80 °C) is determined by the synthetic materials used.The specifications of the relevant manu-facturers apply for motors and control units.

Note on dynamic load ratings and torques

The determination of dynamic load rat-ings and torques is based on a 50, 000 m stroke. If comparative values must be

calculated for a 100, 000 m stroke, the values for Mx, My, Mz and C must be divided by the factor 1.26.

Expedient load

With a view to serviceable life, loads of less than 20% of the dynamic load rat-ings have generally proved to be expedi-ent.

Permissible deflection

Bridge modules may be assembled self-supporting. However, the deflection (which limits the possible load) must be taken into consideration.

If the maximum permissible deflection is exceeded, the bridge modules must be additionally supported.

The maximum permissible deflection is limited by the maximum deflection angle of 5’. Exceeding this value without sup-port will have a negative effect on the unit’s service life.

If increased demands are made on sys-tem accuracy we recommend supporting the bridge module along its entire length.

The following diagrams apply for:– firm clamping (40–50 mm per side)– 3–4 screws per side– solid base

Mounting positions: horizontal

Limit switches

The limit switches are used in conjunc-tion with a control unit to limit the stroke (prevent overrunning of the carriage) and to define the reference position.

LINE TECH employs the following stand-ard inductive limit switches:

– PNP openers (PNP-NC) Supply: 10...30 V DC Current consumption off-load: < 10 mA Load: max. 200 mA

On request the following non standard limit switches are available:

– PNP make type (PNP-NO)– NPN break type (NPN-NC)– NPN make type (NPN-NO)– Reed switches– Mechanical switches

Note: At the factory the plus and minus limit switches are preset to a nominal stroke of 0 to +5 mm.

fitting position of limit switches

The following diagrams show the moun-ting position of the limit switches. The reference position can be allocated either to the plus (+) or to the minus (-) limit switch.

Special applications often require a sepa-rate reference point switch to be mount-ed between the positive and negative limit switches. The limit switch closest to the motor mounting (limit switch control-ler interface) is known as the forward limit switch.

Note: If a lateral support rail (type LM…L/R) or a lateral profile (type BM...V/W) is selected, the limit switches can only be fitted on the opposite side.

Limit switch with/without connector box

Plug connector

The connector pin assignment when using a connector box is shown in the diagram on the right. The individual pins are assigned as follows:

Pin 1 Minus (–) direction (load)Pin 2 0 V (GND)Pin 3 Plus (–) direction (load)Pin 4 +10...30 V (DC)Pin 5 Reference (load)

Colour code key for the diagrams:

Load = black+V DC = brown0 V (GND) = blue

Limit switch preparation

Limit switches are supplied as standard without connector box with 2 metre long cables (order code N); a connector box with completed cabling is available as an option (order code S).

Limit switch mating connectors and cables are not included in the delivery but can be ordered ready-made from LINE TECH.

Standard: without connector box (N), with loose connector cables (L = 2 m)

Optional: with connector box (S)
