Gearbox Design Helps to Prevent Motor Shaft Slippage April 10, 2014

All GAM inline gearboxes feature a radial clamping collar as the connection method to secure the motor shaft.  We’ve had many customers call us and ask for a gearbox with a keyed input because they’ve had motor slipping issues while using other manufacturers’ gearboxes.  These other gearboxes have a set screw design to connect to the motor shaft.  Depending on the type of set screw used, the set screw either presses against or penetrates the motor shaft to generate the holding force.  While there can be many factors that can contribute to the motor shaft slipping, having the holding force come from a single point isn’t an optimal design.  A better option than a set screw or keyed connection uses a radial clamping collar.

With this design, the radial clamping collar compresses the gearbox input shaft and evenly distributes the clamping force around the entire circumference of the motor shaft.  The gearbox input shaft is sliced in three locations to ensure a secure connection even if the motor shaft has a key slot with the key removed. 

Not only does the radial clamping connection generate higher clamping forces, but it won’t mar the motor shaft like a set screw connection can.  And due to the design of the radial clamping collar, the gearbox input shaft has a smaller diameter, resulting in a lower moment of inertia compared to a gearbox with a set screw input.  This radial clamping design comes standard on all GAM inline planetary gear reducers even including the low cost PE series.
