Balancing Machines for Axle Drives with Fully Automatic Unbalance Correction Series SBAL

Fully automatic measuring run
Force-measuring bearing pedestals
Fully automatic unbalance correction by drilling into the input flange
CAB 850 measuring unit
Simulation of environmental conditions by so-called dummy-balancing

Range of application

Measurement and correction of the unbalance of front and rear axle drives
Application of the machine in axle drive production
Low-speed measurement of unbalance at approx. 1500 min-1
Unbalance correction by drilling into the axle drive input flanges (welding available as option)

Design

Machine design optimally adapted to the task. Arrangement of machine assemblies based on ergonomic principles. Available as 1- or 2-station machine.
Welded machine base of special design. Force-measuring bearing pedestals with auxiliary balancing frame, adapted specifically to the axle drive in hand.
Pneumatically operated gear clamping mechanisms restrain the axle drive during the balancing process.
Automatically operating drive unit with active tooling and automatic correction unit. High-performance chip extractor for removing drilling chips in the machine working area.
