Switch over to efficiency: Two-speed gearboxes.
High-quality workpieces need to be manufactured and machined economically and efficiently. And this is where we come in with our innovative PS SensorShift gear unit. Operable in two gear stages with different gear ratios.
And why are two-speed gearboxes so interesting? It’s a high-precision, helical planetary gearbox, perfect for high torques in the transmitted gear. And at the same time, it is designed for high speeds – decoupled in a loss-optimized direct gear. Combined with digital gear shift monitoring for a smooth gear change.
STOBER two-speed gearboxes are extremely energy-efficient, which is one of their most outstanding properties.
The energy savings are primarily the result of a design that is more innovative than previous solutions on the market. The shifting process, between a gear stage with a transmitted gear and a stage with a loss-optimized direct gear, lets you reach high speeds or high torques within an extremely short time. What is outstanding is that gear shifts are digitally monitored.
Two-speed gearboxes: The temperature of the gear unit also remains constantly low, even when there are frequent gear shifts or maximum speed loads.
PS gear units are ideal for all machine tools that need sophisticated drive concepts for main feeds: gantry machines, vertical and horizontal lathes, or milling and drilling centers.
The transmitted hear of the PS series works with a proven helical STOBER planetary gear unit. The various gear ratios in this gear stage deliver high torques and are perfect for machining hard materials. In this precision design, the helical gearing is what also guarantees highly smooth operation.
In direct gear, however, the planetary set is completely decoupled. In this design, the engine torque is transmitted almost without loss – as if there were no gear unit in between. They let you reach high speeds quickly for tasks such as fine machining workpieces, for example. Energy losses are almost completely eliminated, while the dynamics increase significantly.
Get the benefit of a very unique concept: STOBER SensorShift – a special digital gear shift control developed for shifting between the two stages.
The critical moment in shifting is when the gears mesh together just after the planetary gear is activated in the transmitted gear. SensorShift detects this moment in advance and briefly reduces the velocity. This reduces the shifting error rate to less than 0.01%!
The gentle acceleration and deceleration ramps also protect the mechanics while increasing the service life.
By the way, SensorShift has a completely non-contact design and is therefore free of wear. The number of gear switches is counted and stored. Another plus: The split-second teach-in function makes mechanical setting, as for limit switches, absolutely unnecessary.
