S-II-0841-MC precision spur gear slew drive is used in the field of automation. The product is installed vertically and has a large tilting moment. The spur gear slewing drive is used to drive the workpiece to rotate at different angles. The angular error requirements are very small and need to be guaranteed within 0.01°. According to the customer’s use requirements, the code S-II-0841-MC spur gear slewing drive was recommended to the customer. The slewing bearing height of the II series slewing drive is higher, the load and tilting moment are relatively large, vertical installation is more stable. What’s more the gears are designed with a small modulus, which can better reduce the angle error and increase the gear ratio, customers can choose to use reducer with small gear ratio to cooperate with their machine. The overall cost is lower and the total transmission error is smaller. In the design process, the factors that affect the transmission accuracy are minimized, continue to optimize the design, reduce the difficulty of production and improve the reliability of the spur gear slewing drive.
During the production processes, all steps are strictly in accordance with the technological requirements. As for housings, casting, annealing, rough machining, finish machining to ensure the stability and accuracy of the mounting base. As for the slewing rings, forging, rough machining, tempering, semi-finish machining, quenching, finish machining, gears grinding to ensure slewing bearing clearance, runout and gear accuracy. As for pinions, forging, rough machining, tempering, finish machining, gear machining, quenching, grinding and keyway machining to ensure transmission accuracy. The adapter flange is still designed and produced according to the customer’s connection size to provide customers with the greatest convenience. The quality control of the parts is strict in early stage, finally the final assembly is easily completed, assembling, testing, issuing inspection reports, packing and shipping without a break. Another precision spur gear slewing drive is sent out from Unique Transmission to serve customers.
