Note:
- Ball & Roller combined slewing bearing is applied for heavy axial loading, the eccentric rate(e) less than 1.2 and continuous rotating and long life.
- Refer to Table A if slewing bearing are stuck with double row sealing; Refer to Table B if slewing bearing are with labyrinth seal.
- If you need more information about the structure please contact with us.
- The gear torque is under atmosphere of Q&T
The slewing bearing is an important part of the excavator. In simple terms, in addition to the role of "connecting up and down", it is more important that it is the basic guarantee for the excavator to rotate 360 degrees.
Due to the different working conditions of slewing bearings, most of them work under eccentric load. In addition to bearing axial load and radial load, the bearing must also overcome the effect of overturning moment. Therefore, the bearing selection calculation is based on the load-moment diagram. The curve is the method commonly used by major manufacturers at present as the selection method of slewing bearings
Slewing bearing price, High speeds, high loads and salty environment require strong and precise components. The Fenghe slewing rings is the perfect answer to the offshore industry. Our specific design satisfy the main manufacturers of onboard and harbour cranes, winches, davits and rubber tired gantry cranes as well as propellers. We propose innovative solutions of sealing to completely protect the bearings from the environment. fenghe follows the international certification standards.
China Slewing Ring Bearing Manufacturers, Excavator Slewing Bearing, For the slewing ring manufacture, Fenghe selects the best material specifications to suit most foreseen usages.These materials are manufactured by approved steel works.
According to different structural types, Fenghe slewing bearings can be divided into four-point contact ball slewing bearings, double-row angular contact thrust ball slewing bearings, crossed cylindrical roller slewing bearings, crossed tapered roller slewing bearings, and three-row cylindrical roller combined slewing bearings. The above-mentioned various types of bearings are divided into different structures such as gearless external gear or internal gear according to whether they have teeth and the distribution of gear teeth.
The double rows ball slewing ring consists of two parts slewing rings, which can withstand large axial loads, radial loads and titling moments, and has a higher safety factor. It is widely used in medium and large cranes, mining equipment, excavators and other mechanical equipment.
Fenghe's worm gear and worm rotary drive includes two categories: cylindrical worm and envelope worm, of which cylindrical worm is suitable for medium speed. Heavy-duty applications while the enveloping worm is suitable for low-speed heavy-duty and high-precision applications, the worm gear and worm rotary drive can be self-locking, in the power movement The domain can provide basic security and further simplify the overall design of the equipment, and is an excellent industrial accessory.
The worm-gear type slewing drive is developed by the slewing bearing. It is composed of housing, a turbine ferrule, a worm gear, a motor and kits. Compared with the conventional slewing bearing, the structure is compacted, safe and modularity. The characteristics of modify the main engine. Nowadays, due to the demand for heavy loading, the duplex worm slew drive device has been developed. It has better product structure compactness and high loading ability and higher output torque.
