The slewing bearing used by SANY ST85F Forestry Industries machine is a single-row ball slewing bearing with internal gear, and the teeth are quenched.
The slewing bearing used by SANY ST85F Forestry Industries machine is required to carry a large axial force, overturning moment and gear circumferential force, and has higher requirements on the clearance, installation size and material of the slewing bearing. Selecting a suitable slewing bearing can effectively improve the safety and stability of the equipment, and tooth quenching can improve the wear resistance of the teeth, thereby increasing the service life of the slewing bearing.
Gear Heat Treatment
Special heat treatment design is carried out according to the different needs of specific industries for gears, mainly including induction single-tooth quenching and induction-type integral tooth quenching. Single tooth quenching is divided into tooth surface quenching and tooth surface and root quenching. After quenching, tempering treatment is carried out to make the surface hardness and the depth of the hardened layer meet the design standards. The most advantageous process is the special process of integral tooth quenching, which can improve the transmission efficiency and increase the wear resistance and impact resistance of the tooth surface, so as to meet the needs of customers.
The raceway heat treatment of the slewing bearing is realized by induction heat treatment technology. Longwei transmission Slewing Bearing has advanced heat treatment equipment (processing equipment and testing equipment) and scientific processing technology, so that the depth and hardness of the hardened layer conform to JB /T2300-2018 slewing bearing standard.
The inner and outer gears of the slewing ring are directly toothed on the inner or outer ring, and are processed by a gear hobbing machine or a gear shaper. If the working environment is loaded, it needs to be quenched. The internal gear slewing ring: the overall appearance is relatively neat, There is no need to install a safety cover at the meshing part of the gear and the slewing ring. The gear has better dust resistance, longer retention time by adding lubricant, and lower transmission contact stress of internal gear meshing, less wear and longer service life.
Raceway heat treatment and tooth heat treatment are the biggest advantages of longwei transmission slewing bearing co.,ltd.
Tooth heat treatment is an important process in the processing of slewing bearings, and the application of some products requires relatively high hardness of the tooth surface. Through high-frequency induction hardening, the bearing tooth surface can be hardened, effectively increasing the strength and service life of the product. We can perform single tooth quenching or overall quenching according to the modulus and product design requirements.
When continuous induction heating quenching is performed on the raceways of the slewing ring gear and the rolling ring, attention should be paid to the connection between the starting point and the end point of the slewing ring quenching. If the slewing bearing quenching belt overlaps, cracks are likely to occur. For this reason, a certain distance should be maintained at the head-to-tail quenching connection of the slewing ring.
