MODEL SERIES - GBW
SPUR REDUCTION GEARHEAD
Design - Gearhead GB W contains heavily loaded steel gear wheels. The spur gears are fixed on steel spindles which are hardened and polished
to a mirror finish & rotate in sintered bushings. The thick output shaft rotates in robust sintered bushings. All the gears are housed in between metal plates & closed by plastic dust cover. All bearings are permanently lubricated and therefore require no maintenance. GB W can also be combined with small to medium sizes of DC motors (up to Ø52mm). Output shaft can also be emerging from the rear side or both sides. Potentiometer can be mounted on to the gearhead & connected to the output shaft by means of a gear ratio (standard = 1.5:1; others possible). Instead of rotational, linear drive also possible (on demand only). Linear versions with 1mm & 1.25mm pitch available.

Limit switches are necessary for the independent delimitation of movements at cranes, lifting witnesses and similar transporting equipments. A further application results for the execution of monitoring and tasks of bolting device. The rules for the prevention of accidents require that with powered lifting gears the upward motion must be limited by a limit switch. It must still permit the downward movement after its responding. With corridor-served gantry cranes with stationary control stand limit switches are prescribed for the crane and crab traversal. The limit switches are implemented with transmission, spindle or lever drive and can switch their full achievement up to 600mal per hour.
