LINE TECH Linear Modules
Design fundamentals
LINE TECH Linear Modules
LINE TECH linear modules are of modular conception, ready to built-in linear car-riages with drive unit. A linear rail guide with two guiding carriages is used as guiding element. The drive unit preferably consists of ball screws or toothed belts. With little axial load, also high-helix lead screws “Speedy” can be used. The guidance as well as the actuation are protected by a steel strapping or by the drive belt against the intrusion of dirt, chipping etc.The housing as well as the cradle are made of colorless anodized aluminium bars, prefabricated in an extrusion mold-ing process. Additional, external mounted inductive proximity switches allow, in conjunction with servo drives or step motors and the control unit, for the perfect positioning and prevent from the carriage over run.
Lubrication
LINE TECH linear modules stand for a long lasting, maintenance free use. The guide system is therefore equipped with a specially developed device for continuous lubrication.Only the ball screws shall be lubricated approx. every 500 running hours through the provided grease point.
Service temperature
The permissible service temperature of 80° C is predetermined by the compos-ites in use. For the motors and controls refer to the values in the respective publications.

Drive
In order to simplify the selection of the optimal drive, you’ll find hereafter the vari-ous drive solutions in line with the most important performance data.This allows for the comparison of the dif-ferent drives and the selection of the drive solution appropriate to the customers individual need.
In case of any specific or higher require-ments to the positioning system we ask you to get in contact with LINE TECH customer service.

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. The widely used and LINE TECH stand-ard inductive limit switches are of the PNP-break contact type and show the following characteristics:
Supply: 10…30 VDCCurrent consumption off-load: < 10 mA Load: max. 200 mAMechanical switch-ratio: ≤ 0.4mm
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)– Mechanical limit switch (micro switch) The LINE TECH product range includes continuous- and linear path control sys-tems as well as step motors, AC- and DC servo drives. The individual components are tuned together and complete LINE TECH elements to custom made posi-tioning systems.
Fitting of the limit switches
The fitting position of the limit switches is shown in picture 13a. The reference position can be allocated either to the plus (+) or to the minus (-) limit switch. Special applications often require a sepa-rate reference position switch which will be, upon customer definition, located between the plus and minus limit switch. The limit switch mounted closer to the drive (electrical motor) is named the front or forward limit switch.
Limit switch-counterplugs with cable are not included in the delivery. However they can be ordered ready-made at LINE TECH (picture 13b).
On request the limit switches can be con-nected to a connector shell (picture 13b).
The limit switch cable (article ES31.2P) is equipped with a plug on one side.

Load rates
Load rate
The load rate is given by the guiding sys-tem. Considering the requested life time we recommend to apply max. 20% of the dynamic load rate to the unit.
Torque
Also for the torque, the values are de-termined by the execution of the guiding system. The illustration at right (picture 15) shows the directions of possible torque application.
Area momentum
For positioning units the maximum al-lowed deflection angle is of 5’. This value being exceeded will have an impact on the unit’s life-cycle.

Dimensions motor mount
The basic dimensions for the drive mount are shown in this chapter. The dimen-sions shown in pictures 16 to 19 are also valid for the respective axially symmetric executions (drive mount left or bottom).The drive mount is likely to protrude above or below in most cases (depending on the size of the drive and the module respective.

Grooves and sliding blocks, Profile cross-sections LM3
Grooves and sliding blocks
For all unit sizes the profiles, and often the carriages as well, come with grooves. The cradles of the linear modules LM4 and LM5 are not equipped with such. The fixing on those two types is made through threaded holes.The positions of the grooves as well as the maximum thread reach are shown in profile cross-sections.
According to the groove width, sliding blocks of the types NS5, NS6 and NS8 are suitable. The sliding blocks are available at LINE TECH. The order number must show type, material and thread size (e.q. NS5 St M5). The available types are shown in the chart beside.

Concept
The determination of service life must be calculated based on the respective documents of the linear guide bar system and the ball screw drives. Also for the drive belts we shall refer to the specific literature.It is the guide bar or guide roller system which normally determines the service life. Therefore the following rules can be applied for a coarse definition.
Dynamic load
The nominal service life L10 is being calculated from the dynamic load factor Cdyn [N] and the applied load Fr [N]:
Cdyn 3
L10 = (––––) [105 m run] Fr
Static load
in case of only static load to be applied, the static index fS is being calculated in
order to show that a module with an ad-equate load capacity has been selected. Taking into account the static load factor C0 [N] and the load Fr [N] it results:
C0fS = –––– Fr
If fS ≥ 1, the safety margin is sufficient.If fS ≤ 1, contact LINE TECH for further advise.
Remark
The above formulas are applicable only in case all bearings are equally loaded, i.e. the load Fr F is applied at the center of the cradle. Especially in vertical ar-rangements of the linear modules, the drive (screw or belt) must be checked. LINE TECH disposes of different test programs. If you provide us all the necessary infor-mation, we’ll be pleased to assist you.
Definition of the drive motor
The drive motor forms the link between the control signal and the movement to be applied to a given load. Size and type of the drive motor primarily depend on the load, the required displacement speed and the acceleration factor. Cal-culation and choice of a positioning unit shall be based on the worst case service conditions. For the optimal drive unit configuration, LINE TECH offers you different types of step-motors, DC and AC motors together with the appropriate continuous- or linear path control.To allow you the determination of the adequate drive motor for any specific application, always use the formulas and examples shown hereafter.
