Linear Solutions Technology − short and to the point
Linear drives are motor-gearhead combinations with a spindle as gearhead output. The high radial and axial forces are absorbed at the gearhead output via a reinforced bearing, which eliminates the need for external support. Linear drives have advantages when it comes to installation complexity and overall length, and they can be used in numerous combinations with motors and feedback sensors. Versions with ceramic components, metric spindles, ball screws, and trapezoidal screws are available.
Spindle drives Properties
Customized linear motors and integration In addition to rotary drives, maxon produces customized linear motors and complete linear drive systems. Our engi- neering teams support customers from the requirements analysis through develop- ment to industrialization, in order to deliver precisely tailored solutions, even when standard products fall short.
– Standard length and thread pitch. Other lengths and thread pitches available optionally – Standard thread nut. Optional flange nut or cylindrical nut – The output stage and spindle are axially preloaded in their bearings. This allows the high axial forces to be absorbed directly by the gearhead without additional support
In the process, we seamlessly integrate motor, sensors, electronics, and mechani- cal systems into the customer application; on request, complete mechatronic systems can be provided, optimized for specific environmental conditions and load pro- files. Please contact your local maxon sales organization.
Metric spindles Properties – Self-locking – Low costs Metal spindles – Efficiency < 30% – Spindle diameter M2.5 to M10 Ceramic spindles – Higher load than metal spindles – Efficiency up to approx. 40%
Ball screws Properties – High efficiency (> 90%) – Not self-locking – High load capacity – Spindle diameter 5 mm to 10 mm
Trapezoidal screws Properties – Self-locking – Low costs – Efficiency < 50% – Higher load capacity than metric spindles – Spindle diameter TR10
