High Speed Automation HPLA Series
The HPLA is a rugged “next generation”
linear module that offers high speed, high acceleration, and long travel, combinedwith stiff, rigid construction characteristics. It is ideally suited as a single axis product or as a component for high speed multi-axis gantries.
The HPLA carriage is rigidly supported on three sides by heavy duty
caster bearings, housed in a rugged alumi-num housing. The bearing wheels are pre-loaded via eccentric bushings to eliminate play in the system, and are strategicallylocated to evenly distribute the load across the length of the carriage. A high strength drive belt and pulley system provides
fast and highly repeatable positioning of the carriage. This high thrust drive belt is securely connected to the carriage by a
unique
vise system. This system provides a secure connection and enables easy belt replacement without the need to
remove the payload. Having a low coefficient of friction, the carriage design provides a high mechanical efficiency and long
service life. Special carriage lengths and
linear systems with multiple carriages are available for custom applications.
Drive Station Drive Belt Carriage
The drive stations are designed to acceptplanetary gear reducers or provide differentshaft outputs for driving the HPLA. A zero backlash, steel reinforced timingbelt provides high speed, high force, andhigh acceleration. A serrated clamp
mechanism between belt and carriageguarantees a safe, strong connection andallows belt replacement without removing
the load. Roller bearing wheels are installed on threesides of the carriage to provide smooth linearmotion and support. The wheels are
positioned to evenly distribute the loadacross the length of the carriage. Eccentricbearing wheel bushings are adjusted to
eliminate play on all sides of the carriage.The carriages are available in standard andextended lengths.
Tensioning Station
An easily accessable tensioningstation is used to set the drive belt
tension.
Housing
An extruded
supplier of aluminum profile provides
maximum rigidity (torsion and deflection) at
minimum weight. It is designed to accom-modate both steel or polyamide rollerbearing wheels. The polyamide wheels ride
in the extruded guideway and the steelwheels ride on integral hardened steelbearing ways.
Magnetically attached stainlesssteel seal strip (not shown in thisillustration) provides environmen-
tal protection to interior compo-nents.
Roller Bearing
Three rows of preloaded heavy duty steel
roller
bearings supplier provide the highest loadcarrying capability available. Each rollerbearing incorporates a low friction,
lubricated and sealed radial ball bearingenclosed in a hardened steel outer ring(or raceway). A polyamide tread can be
substituted for the steel ring wheneverwhisper quiet motion is desired.
