Planetary gearbox assembly lines for gears and industrial transmissions
Sytec designs and builds automated assembly lines for the production of mechanical components
MECHANICS
Automating the assembly of gearboxes and transmissions
A planetary gearbox contains dozens of components that must fit together with micrometric precision. Recirculating ball screws require a preload calibrated to the hundredth of a newton. Roller chains have to endure thousands of cycles with no elongation outside tolerance. In all these cases, manual assembly introduces a variability the product cannot tolerate.
Companies that produce transmission components know the problem well: sample quality control that is no longer enough, and throughput that cannot keep up with demand. The answer is an assembly line designed around the specific component, where every operation is controlled and every piece is traced.
What Sytec does for the transmission sector
Sytec designs assembly lines dedicated to power transmission assembly and the production of mechanical transmission components. Depending on the component, the stations handle different operations.
Planetary gearbox assembly: satellite insertion, planet carrier fitting, bearing keying, crown and pinion assembly including helical gear assembly, backlash control and load testing.
Recirculating ball screws: ball insertion, nut fitting, preload adjustment, sliding check and axial load testing. The same stations also handle lead screw assembly.
Roller chain manufacturing: link assembly, pin insertion, riveting, pitch control and tensile load testing.
For belt drive assembly and worm drive assembly: pulley fitting, tensioning, alignment and functional testing of the whole unit.
In every configuration, the gear inspection equipment verifies the critical dimensions of every assembled component. Sytec’s proprietary software manages the assembly recipes for each product variant and transmits all data to the customer’s systems.
Precision and flexibility: two requirements that are not mutually exclusive
Manufacturers of gearboxes and transmissions often manage catalogs with dozens of variants: different reduction ratios, different sizes, different shaft configurations. Sytec designs lines that move from one variant to the next with no stoppages, adapting fixtures, tightening programs and testing parameters automatically. The result is a system that keeps the precision of dedicated assembly together with the flexibility of a line that runs multiple products.
Every system is designed and built internally at the Sytec plant. Industrial robots are integrated into the stations where speed and precision matter, from handling the gears to loading the bearings.

Sytec lines for planetary gearbox assembly, transmission assembly and roller chain manufacturing integrate dimensional control and functional testing stations directly into the production flow. Every gearbox, every ball screw and every roller chain is measured and tested before leaving the line. Assembly and testing data is captured and archived automatically, ensuring complete traceability from the single component to the production batch.

From the single station to the complete line for the transmission sector
Every manufacturer of gearboxes and transmissions starts from a different point. Some look for a single planetary gearbox assembly station to integrate into an existing line. Others need a complete system, from component feeding to final testing. Sytec handles both scenarios, designing scalable solutions that grow with the customer’s needs.
The expertise built up in the assembly of electric motors, electromechanical components and hydraulic components lets Sytec manage even the most complex mechanical products, from planetary gearbox assembly to power transmission assembly. The company also operates in the automotive and medical sectors, as well as in all the main areas of the industrial sector. Thanks to ISO 9001:2015 certification, every system meets the quality standards required by customers.
