Spur Gearheads

Spur Gearboxes from Maxon

Spur Gearboxes are made with straight teeth mounted on a parallel shaft. The noise level of spur gears is relatively high due to colliding teeth of the gears which make spur gear teeth prone to excessive wear.

If mechanical power is required at a high torque and correspondingly reduced speed, a Maxon precision gearhead is recommended.  According to the gear ratio, the output speed is reduced while the output torque is enhanced (less efficiency losses).  Maxon Spur Gearheads consist of one or more stages.  One stage represents the pairing of two cogwheels.  The first cogwheel (pinion) is mounted directly on the motor shaft.  The motor pinion is the input for the first gearwheel stage and is rigidly affixed to the motor shaft.  Gears are precisely installed directly to the pinion to obtain optimum gear efficiency.  The bearing of the output shaft is usually made of sintered material.  Spur gearboxes are economically priced and preferable in low torque applications.  Maxon Spur Gearheads are offered in size ranges 12mm to 45mm OD.  Features include:
