Embodiment Construction
[0029] The present invention can be explained in more detail by the following examples, and the present invention is not limited to the following examples;
[0030] combined with Figure 1-2 The processing technology of the double-row different-diameter ball type large-scale slewing bearing, the double-row different-diameter ball large-scale slewing bearing includes internal gear type and external gear type, and the process steps include forging customization, soft turning and Raceway processing, the specific operation steps are as follows:
[0031] (1) Customized forgings
[0032] The internal-tooth double-row ball-type large slewing bearing with different diameters includes outer ring A, outer ring B and an inner gear ring. When the forging is formulated, the outer ring A and the large end faces of the outer ring B are bonded together to form a combined forgings, and set the cut-off knife edge and the allowance of the cut-off surface on the combined forgings; the external ...

A processing technology for a double-row ball type large-scale slewing bearing, which relates to the technical field of bearing processing. The double-row ball type large-scale slewing bearing includes an internal gear type and an external gear type. The process steps include forging customization , soft turning and raceway processing. When the forgings are formulated, the large end faces of the inner ring A (1') and the inner ring B (2') are fitted together to form a combined forging, and a cutting edge is set on the remaining amount of the combined forging. (3') and the reserved amount of the flat section of the car, and then rough machining the internal tooth type combined forging according to the incoming material size of the combined forging, and finally the bearing raceway (4) and the bearing raceway (4') using variable Curvature processing; the invention not only ensures the product quality, but also effectively solves the problem of residual quenching oxide skin at the chamfering of raceway groove mouth.
Description
[0001] 【Technical field】 [0002] The invention relates to the technical field of bearing processing, and in particular the invention relates to a processing technology of a double-row different-diameter ball type large-scale slewing bearing. [0003] 【Background technique】 [0004] Known, double-row ball bearings with different diameters have three ferrules, which are processed according to the conventional process. The three parts are individually customized forgings, and then the three forgings are processed normally, but if the part of the ferrule is separated, If the thickness of the two outer rings or the two inner rings is relatively thin, the deformation of the parts after the heat treatment of the raceway is too large, and the subsequent normal processing cannot be guaranteed. Cracks are prone to occur when cracking, and the depth of the hardened layer will also be affected to a certain extent. [0005] 【Content of invention】 [0006] In order to overcome the deficie...
