Our quality control system is equipped with advanced inspection equipment, and we comply with international standards such as ISO 9001:2008, TS16949, and ROHS certified by SGS.
Below is a detailed specification table:
Established in 2020 and officially put into the market in 2022, it is one of the leading products of Xingtai Zhongwei Zhuote Hydraulic Technology Co., Ltd. Widely used in construction machinery, engineering machinery, port machinery, metallurgy machinery, light industry machinery, wind power generation, medical CT, military industry and other fields, and exported to Europe, America and Southeast Asia in batches.
As the "joint of the machine", the Swing Bearing is an important transmission component necessary for the machine that needs relative slewing motion between two objects and bears axial force, radial force and tilting moment at the same time; It is a mechanical component integrating supporting, rotating and fixing functions, which can greatly simplify the manufacturing, installation and maintenance of the host.
In order to adapt to different use requirements, there are many structural types of Swing Bearings.
(1) The rolling elements can be divided into point contact type and line contact type according to their types;
(2) It can be divided into single-row, double-row and three-row roller types according to the structure type;
(3) It can be divided into internal toothless type and external toothless type according to the gear form.
It is mainly composed of outer ring, inner ring, ball, spacer block and sealing belt. The four-point contact between ball and arc raceway can bear radial load, axial load and tilting load at the same time. Small and medium-sized engineering machines, such as small and medium-sized cranes and excavators, hydraulic excavators, rotating machinery, large and medium-sized excavators and other engineering machinery can be selected.
(1) The nominal contact between rolling elements and raceways is point contact (in fact, it becomes surface contact after being loaded, but the contact surface is still small), and the slewing resistance is small;
(2) The manufacturing error of raceway, installation clearance, elastic deformation of rolling ring and seat frame have little influence on the contact condition, so the above points are less sensitive to the bearing capacity;
(3) The contact stress is higher than the line contact, and the shear stress formed under the surface of the raceway during movement is larger, so the dynamic bearing capacity is lower than the line contact;
(4) The raceway section is curved, so it is slightly difficult to process and grind.
ZHTE HYDRAULIC has an existing rolling production line for Swing Bearings, which can produce single-row row Swing Bearings. Carefully select medium carbon alloy steel as the raw material, and produce the raw blank through the rolling production line. This process can accurately control the accuracy of the blank, change the material performance, reduce the material stress, improve the material density, greatly improve the wear resistance of the material, and extend the service life of the parts.
The following operations will be carried out after the inspection of the original blank is qualified:
(1) Thermal stress relief of blank
(2) ROUGH TURNING - FINISH TURNING - DRILLING - SERRATION - FINISH GRINDING
(3) Raceway quenching treatment
(4) Gear quenching treatment
(5) Product inspection
Billet inspection - tempering inspection - quenching depth inspection - crack inspection - with clearance inspection - assembled finished product inspection
(6) Install the nameplate
