What is the The SG-H Spur Gear Slewing Drive

High Load-Bearing Capacity: It adopts a double-row slewing bearing design, which can withstand large axial forces, radial forces, and overturning moments, meeting the requirements of various high-load working scenarios, such as port cranes, columnar palletizers, and other equipment.

High Transmission Efficiency: By using gear transmission, compared with some other transmission methods, it has less energy loss, can transfer power quickly and accurately, and achieve efficient slewing motion, effectively improving the working efficiency of equipment.

Compact Structure: The design of an external gear slewing bearing and a small gear takes up less space and is easy to integrate into various mechanical equipment, facilitating the lightweight and miniaturized design of equipment and saving installation space.

Good Protection Performance: With a fully enclosed design and an NBR rubber seal, it reaches an IP65 protection level, providing excellent dustproof and waterproof effects. It can effectively prevent external pollutants from entering the interior, protect internal components, extend the service life, and reduce maintenance costs.

High Slewing Accuracy: Through precise gear processing and assembly technology, it can ensure high slewing accuracy, meeting the requirements of high-precision automated equipment and industrial applications, such as robotic arm bases and automated inserters.

The SG-H Spur Gear Slewing Drive has many remarkable advantages

Efficient Transmission: The spur gear design enables more direct power transmission, effectively reducing energy loss and greatly improving transmission efficiency. Compared with other types of slewing drives, it can achieve a larger output torque with a smaller input power. In fields such as aerial work platforms and logistics handling equipment, it allows the equipment to complete slewing movements quickly and accurately, significantly improving the operation efficiency.

High Load-Bearing Capacity: It is made of high-strength materials and features an optimized structural design, capable of simultaneously withstanding huge axial forces, radial forces, and overturning moments. When used in cranes and port machinery, even when lifting heavy objects and rotating frequently, it can operate stably, ensuring safe and reliable operations and reducing equipment failures caused by insufficient load-bearing capacity.

Easy Installation and Maintenance: With a simple and compact structure, it requires less installation space, facilitating integration into various types of equipment, reducing the overall design difficulty and cost of the equipment. Moreover, its components have strong universality, making it easy to obtain replacement parts during maintenance. The maintenance process is simple, which can shorten the downtime and improve the equipment utilization rate.

High Precision and Stability: With excellent manufacturing processes, high tooth profile accuracy, smooth slewing, and precise positioning. In precision machine tools and laser processing equipment, it can ensure processing accuracy, avoid affecting product quality due to slewing errors, ensure stable equipment operation, and extend the service life.

The SG-H Spur Gear Slewing Drive has the following special structural designs:

Slewing Bearing: Usually, a four-point contact ball type is selected, which has the ability to simultaneously withstand axial and radial loads and overturning moments and performs well in terms of rotational speed. In special working conditions, such as when facing large overturning forces, high impacts, and high vibrations, a crossed roller type or three-row roller type slewing bearing can also be used. The material is a 42CrMo forging that has been quenched and tempered to improve its mechanical properties and load-bearing capacity. The raceways and teeth are induction hardened to meet the hardness requirements, with the characteristics of a hard surface and a soft core, providing strong load-bearing capacity, wear resistance, and impact resistance.

Gear: The material is also a 42CrMo forging that has been quenched and tempered. The shaft hole is mated with the reducer shaft or motor shaft to transfer kinetic energy. A sliding fit is used and precision grinding is carried out to ensure accurate dimensions. The gear is designed with universal bearings supported at both ends. It does not rely on external shaft support and can rotate independently. It can withstand high radial forces and has high reliability in large-impact and large-inertia working conditions, effectively reducing external shaft damage and reducing the failure rate.

Housing: It is cast from nodular cast iron QT450 – 10 and normalized. Its mechanical properties are close to those of steel. It has excellent castability, small processing deformation, high strength, wear resistance, and durability, providing stable protection for internal components.

Adapter Flange: It plays a crucial role in connecting the upper and lower parts. It can fix the gear to ensure its stable rotation and also serves as the input end to connect to the output flange of the reducer or motor. Generally, it is customized according to the dimensions of the equipment selected by the user. Flexible solutions are required to address various special issues during the design process.

Support Bearings: According to specific working conditions, universal bearings such as angular contact ball bearings and tapered roller bearings are reasonably selected to support the rotation of the gear.

Seal: An NBR oil-resistant nitrile rubber seal is used to seal the raceway of the slewing bearing and the area between the slewing bearing and the housing, achieving dustproof and waterproof effects and reducing the frequency of maintenance and servicing.

The Price of the SG-H Spur Gear Slewing Drive

Related to Load-Bearing Capacity: The higher the load-bearing capacity, the higher the price is usually. Because high load-bearing capacity requires better materials, more precise manufacturing processes, and larger structural sizes to ensure stable and reliable operation when bearing large axial forces, radial forces, and overturning moments.

Affected by Accuracy Requirements: If high slewing accuracy is required, such as for use in precision instruments or high-precision automated equipment, stricter quality control and inspection methods are needed during the production process. This increases the cost and, accordingly, the price.

Differences in Customization Levels: Customized products usually cost more than standard products because they require special design, mold manufacturing, and production process adjustments. For example, customization according to the installation dimensions, interface requirements, or special working environments of specific equipment will increase the cost.
