Workpiece changing tables

Peiseler uses three-piece worm gears, a well-known design developed by Ott. These gears consist of a worm wheel and a two-piece worm, the shank worm and hollow worm. During assembly, we adjust the gear so it is backlash-free. Readjusting the worm during its service life is simple with a commercially available mounting tool. The design advantages are a compact gear ratio, high mechanical precision and the control's excellent regulatory quality. Heat limits the duty cycle.

The benefits for you

• Simple commissioning/easy installation

• Easily adjustable worm gear

• Maximum drive moment and low backlash

• Self-braking (safety feature)

• Cost-effective solution for positioning applications

Peiseler designs and produces lifting and non-lifting Hirth couplings for indexing processes. NC operation is not possible with this technology. Hirth couplings transfer very high loads, particularly tangential moments. They have a very high positioning repeatability. In the non-lifting variant, the rotary tables are designed with an axially fixed bearing. With this special design, the face plate remains in position axially during all movement sequences. Designs with a lifting Hirth coupling lift the face plate by a few millimetres for turning.

The benefits for you

• Various spacings available up to 360 teeth/1°

• Manufactured in house and can be adapted to any installation space

• Form-fitting for maximum mechanical positioning precision & repeatability

• Maximum rigidity in drive train

• Combined with generously proportioned cast housings for an optimum damping performance

• All core assemblies from a single source!

Peiseler designs and produces Hirth couplings as a component of subdevices, spindles and as a centring coupling for shaft force transmission. Our product portfolio includes Hirth sets made of two rings for the lifting mode of operation and three rings for the non-lifting mode of operation. High-quality, heat-treated steels allow us to integrate bearing running surfaces or other design elements. Peiseler primarily delivers Hirth couplings according to customer specifications.

We build rotary manifolds for air, water, cooling lubricant or oil up to 250 bar pressure. We have developed low-friction seals in rotary manifolds to meet the demands of the mould-forming industry and high-speed axis applications. We work with our suppliers to develop special lines of seals with an optimum sealing performance. Coated manifold shafts withstand the loads of the dynamic, continuous movements common in free-form surface production.

The benefits for you

• Developed in house/maximum design flexibility

• Can be adapted to suit any requirements

• Nested design available

• Maximum availability/process reliability

• Low-maintenance

• Compatible with a wide range of media

• All core assemblies from a single source!

Our generously proportioned housings are designed for rigidity and outstanding damping capability to ensure the best possible surface quality for your workpiece.  In dynamic applications, we can optimise the components in house based on FEM calculations. A reduced mass inertia allows for more dynamic axis designs, shortens cycle times and reduces the power consumption of the drives. We always focus on your key requirements.
