2.1 Product construction and description
The profile (1)
By using finite element analysis we
have optimised the aluminium extru-
sion bar profile to maximise rigidity
(torsion and deflection) and minimise
weight.
The modular concept permits the
same profile to be used for all HPLA
variants:
a) drive version with timing belt drive
b) version with rack-and-pinion
c) guide with plastic rollers on alu-
minium
d) guide with steel rollers on a steel
strip which is integrated into the
profile.
6 steel strips (8) are fitted into the
profile of the version with steel rollers.
The profile can be supplied in cross-
sections of:
•
80 x 80mm (HPLA80)
•
120 x 120mm (HPLA120)
•
180 x 180mm (HPLA180).
Two assembly grooves are located
on the two sides and on the bottom.
These can be used in accordance
with DIN-508 for T-nuts to fasten ad-
ditional mechanical components and
to connect several linear actuators.
When combined with the covering
profile (9), this forms cable ducts, e.g.
for the initiator cables.
The carriage (2)
The aluminium carriage profile has
also been optimised using FEA
methods. The plastic or steel rollers
(mounted on roller bearings and lu-
bricated for life) are set via the ec-
centric to eliminate play on all sides.
The carriage can be supplied in two
sizes as the standard carriage with 12
rollers or extended carriage with 24
rollers.
The tensioning station (3)
An easily accessible tensioning sta-
tion which is simple to maintain and
assemble. It is used to set the neces-
sary tension of the timing belt and its
alignment (parallel to the pulleys).
The drive station (4)
The HPLA can be delivered with
numerous drive options. Every-
thing is possible – from the pulley
mounted on gearbox shaft
through a fully supported hollow
shaft up to a drive shaft on left, on
right or on both sides.
The timing belt (5)
The timing belt is slip-free and is re-
inforced by integral steel wires, there-
by ensuring maximum travel speeds
and repeatability.
Clamping of timing belt (6)
The timing belt clamping angle and
the large area of the clamping guar-
antees a secure connection between
the timing belt and the carriage.
The clamping system allows the tim-
ing belt to be replaced without the
load attachment plate having to be
dismantled. This means that attach-
ments do not normally need to be
removed.
The load attachment plate (7)
The longitudinal grooves integrated
on the top of the plate offer many op-
tions for the assembly of attach-
ments. When used in conjunction with
our clamping profiles, this allows for
simple incorporation in a multiple axis
system.
Simple and adjustable attachment of
operating cams or switch lugs is pro-
vided by means of lateral and longi-
tudinal grooves.
Height and bolt points are unaffected
if the steel strip cover is attached at a
later date.
