DynaGear was developed for highly dynamic servo applications requiring exceptional accuracy and efficiency in a compact footprint. DynaGear uses optimized hypoid gears for high, smooth torque transfer with backlash as low as < 2 arc-min. Tapered roller bearings on the input and output sides of the gearbox absorb high radial and axial loads, ensuring long service life. A planetary input is used to achieve higher ratios.
DynaGear uses a weight efficient one-piece aluminum housing for high stability under load. Versatile output mounting options include solid shaft, hollow shaft, dual shaft and robot flange. The extremely compact design provides significant space savings for small installation envelopes. Lubricated for life, DynaGear is a reliable maintenance-free solution.
At nominal input speed, service life is 30,000 hours.
The maximum torque when starting or stopping operation. Permitted 1,000 cycles/hour.
The maximum torque allowed under a stress situation. Permitted 1,000 times during service life.
The average input speed at nominal input torque. Maintain housing temperature below permitted value.
The maximum intermittent input speed.
The maximum radial load the gearbox can accept. Measured at center of output shaft at 400rpm output.
The maximum axial load the gearbox can accept. Measured at center of output shaft at 400rpm output.
The efficiency at full load.
At nominal output torque. Does not include lost motion.
Measured at output, 2% load and max 10Nm.
Measured at 3,000 rpm input.
Based on S5 duty cycle <60% and <20 minute run time.
