SGR today announced that they have been featured as the best planetary gearbox manufacturer in China. This was after a survey that brought together all gearbox manufacturers. The aim of the survey was to review latest technology, innovation, progress and development in gearbox manufacturing industry.
“SGR has continually distinguished itself from the rest of planetary gearbox manufacturers by investing and adopting new manufacturing technologies – we thank our technical staff and customers for their support,” said Dennis Yan, SGR product manager. “We are certain all SGR planetary gearboxes will dramatically improve every aspect in the manufacturing and processing industries. They feature modular designs, case hardening, heavy duty bearing and different torque range.” after won “Science and Technology Advancement Prize” awarded by the National Speed Reducer & Variator Industry Association.
This survey focused on six different types of SGR planetary gearboxes. It aimed to analyze every planetary gearbox to achieve: proportional torque distribution, heavy load bearing capability, transmission efficiency and gear reduction stages for different gear ratios. Also in term of low speed shaft design: Cylindrical with key, internal hollow spline, extensional spline, hollow shaft with shrink disc, High speed design: Cylindrical with key, hydraulic motor, electric motor as well.
Key SGR planetary gearboxes that were featured included:
