The project design of external gear same direction flange precision spur gear slew drive

S-II-O-0941-MC spur gear slew drive, used by customers in automatic machinery and equipment, requires a rotation accuracy of ≤0.01°. The customer’s equipment is relatively high, and the rotating part can only be placed at the bottom, which means that the spur gear slew drive can only be installed at the bottom, in this way, there is no installation space for reducer and motor. Through communication with customer, we understand that there is installation space on the top of equipment. According to the customer’s equipment situation, Unique Transmission customized this external gear same direction flange precision spur gear slew drive to customer, which solved the customer’s problem from the design.This type of gear reducer can solve the problem of insufficient bottom installation space and the gear motor can only be installed vertically upwards, providing customers with great convenience.

S-II-O-0941-MC external gear same direction flange precision spur gear slew drive can install the reducer and motor on top, but sealing is a problem, because the input end of the transmission gear is designed to the top, NBR rubber seals cannot be installed on the outer ring of the slewing ring, can only find a way to install the seals on the housing. Unique Transmission has designed a steel plate seal for customer, which was installed on the housing, sturdy, safe, beautiful and practical to ensure the reliability of the spur gear slew drive. The stability of precision spur gear slew drive is very important. The spur gear slew drive housing was made of thickened ductile iron castings and processed by a machining center. The accuracy and stability are guaranteed.The slewing ring still adopted 42CrMo tempering, negative clearance and gear grinding. The support bearing adopted P5 grade precision bearing. The rich experience of the Unique Transmission design team ensures the rationality of the mutual cooperation between the components, only reasonable cooperation can make precise products.
