TPFR Series

PRODUCT FEATURESS Planetary arm bracket and output shaft are one-piece constructed to ensure maximum torsional rigidity. The gears adopt the full-needle design,in order to broaden the contact area and to increasing the structure rigidity and the output torque. The mild-steel gears' hardness of adopting surface hardening technology is HRC62 ,so that the abrasion resistance and impact toughness can achieve best. Because adopting high technology to design the tooth profiles , the best gear tooth profiles are obtained and the noise are reduced. In case to gain power transmission,the maximum clamping force and zero backlash(ultra-precision) are obtained by adopting double- locked method between the gearbox input side and the motor shaft. Adopt spiral bevel gear design, allow high output torque, more than 30% higher than straight bevel gear. High tolerance input speed, more than 8 times higher than straight bevel gear input. The meshing tooth imprint of spiral bevel gear has been optimized by optimum design, and the contact tooth surface load is uniform, and long running life. Cochlear bevel gears are meshed by optimum motion error analysis and strict process control to ensure high precision running back clearance.
