The new LPK+ gearheads from alpha are the right-angled brother of the LP+ In-Line Low-Backlash Planetary gearhead. It unleashes previously inaccessible areas and increases the potentials for innovations in a host of Servo applications, requiring low-to-medium precision.
In addition to broadening alpha's product spectrum, the new right-angled gearhead marks a conscious step towards becoming a one-stop supplier of Servo gearheads and Mechanical Drive Systems. The benefits united in LK+/LPK+ are its high power density, a torsional backlash limited to 10 arcminutes, high continuous speeds that guarantee maximum productivity and rugged output bearings to prolong the service life.
As well as providing economic efficiency, the gearhead creates unrivalled flexibility. This includes being suitable for any operating mode, installation position or motor type and is also included in Cymex, alpha's sizing software. Designers can use this software to optimise applications featuring LK+/LPK+ and verify such aspects as capacity utilisation, service life and motor mounting. The new LPK+ represents an alternative technology to Servo Worms or Bevel Spur Gearheads for Servo Motors.
The delivery time is normally 1-2 weeks after the start of serial production, but products can be shipped within 24-48 based on the customer's requirements. The New LK+ and LPK+ can optionally be supplied with the alpha Rack & Pinion System or Shaft Couplings solutions. Courtesy of the universal motor mounting system, the gearhead can be mounted to any Servo Motor in just five minutes. From positioning feed axes through motorised auxiliary axes, to heavy-duty loading axes and economical rotary axes, the LK+ and LPK+ are a stable and versatile performer in any application that must meet exacting productivity and reliability requirements.
LPK+ will initially be available in three sizes with acceleration torques up to 250 Nm. It has a torsional backlash limited to <10 arcminutes and a peak speed of 6000 rpm. The gearhead comes with ten reduction ratios from i = 3 to i = 100 (all exact ratios).
LPK+ has many advantageous features, including Cartesian robots with a timing belt drive, (for example, in palletisers and loading/unloading robots). LPK+ assures high rigidity due to its planetary stage on the output side, and withstands high timing belt pre-tension; and owing to its right-angle design, requires only minimal installation space.
Another benefit is the XY axes with a Rack & Pinion Drive in medium-precision flatbed machines. LPK+ unites reliable, efficient precision with a high power density, thus reducing the weight of traversing axes.
LPK+ also features high-speed axes for feeding, cutting, slotting, erecting, sealing, etc. in packaging machines: High speeds facilitated by high efficiency and the right-angle stage in an aluminium housing form the basis for high productivity. Almost zero wear and constant torsional backlash permit consistently high quality.
