Abstract
The invention relates to a single-row tapered roller thrust bearing roller path grinding method. The method is characterized by comprising the following steps of: adjusting a machine tool to a set angle, processing with the outside diameter of a grinding wheel; firstly adjusting the angle of a grinding wheel spindle and coping the angle of a single-row tapered roller thrust bearing roller path, the half angle of the grinding wheel after finishing is the angle of the roller path, then adjusting the angle of the head of the machine tool and the angle of the grinding wheel spindle to cause the included angle between the grinding wheel spindle and a workpiece spindle to be 90 degrees, adjusting the outside diameter of the grinding wheel to be parallel to the roller path, processing the roller path, and completing roller path processing according to the set accuracy, thus the single-row tapered roller thrust bearing roller path is obtained. By applying the method provided by the invention, the grinding wheel is provided with the set angle after being finished and ground, the set angle is matched with the angle of the roller path, a workpiece is polished by the grinding wheel only requiring that an angle of 90 degrees is kept, vertical angle is easy to control, implementation is more convenient, the method provided by the invention is simple and is easy to operate, working efficiency is improved by several times, and product quality can be guaranteed.
Description
Technical field
The present invention relates to a kind of processing method of bearing, be specifically related to a kind of single-row bearing rollaway nest of thrust cone roller method for grinding.
Background technique
Bearing is made up of inner ring, outer ring, a plurality of roller and retainer usually, and a plurality of rollers are installed in respectively in the pocket hole that keeps corresponding on the stand and are placed in the raceway that is made up of inner ring and outer ring, and the retainer lid is fixed on the upper-end surface that keeps stand.And the correction Line of contact of the roller of single-row tapered roller bearing and raceway contact point can reduce stress and concentrates; Tapered roller bearing can bear bigger radial load and thrust load; The raceway at band tilt angle can make tapered roller bearing bear radial and axial joint load; These characteristics make tapered roller bearing become desirable selection in many applications, are single-row tapered roller bearings and use maximum in the tapered roller bearing.
Single-row tapered roller thrust bearing and to depress bearing different with other tapered roller thrust bearing; The raceway wider width of these products; Traditional processing method is to become irregular angle to polish with workpiece emery wheel, according to traditional processing method, and the bad assurance of this angle; Quality can't guarantee, and manufacturing efficiency is lower.
Summary of the invention
The purpose of this invention is to provide a kind of single-row bearing rollaway nest of thrust cone roller method for grinding, utilize this method to process single-row bearing rollaway nest of thrust cone roller, efficient is high, and quality meets standard.
The technological scheme that adopts is:
A kind of single-row bearing rollaway nest of thrust cone roller method for grinding comprises following process step:
Lathe is adjusted to set angle, process with the emery wheel external diameter; The angle of adjustment grinding wheel spindle is carried out reconditioning with emery wheel by the angle of single-row promotion tapered roller bearing raceway earlier; The half-angle of finishing back emery wheel is the angle of raceway, adjusts lathe head of a bed angle and grinding wheel spindle angle again, makes grinding wheel spindle become 90 degree with the workpiece spindle angle; The emery wheel external diameter is adjusted to parallel with raceway; Process raceway, press setting accuracy and accomplish raceway processing, promptly get.
Through evidence, the raceway face roughness of utilizing the single-row bearing rollaway nest of thrust cone roller method for grinding among the present invention to process can meet the demands, and machining angle is accurate, easy to be held, and is difficult for changing, and the fault rate of operative workpiece reduces greatly.
The invention has the advantages that:
The present invention has set angle after with the emery wheel reconditioning, is complementary with raceway angles, as long as become an angle of 90 degrees to polish with workpiece emery wheel; Vertical angle is easy to control, implements more conveniently, and method is simple; Easy to operate, working efficiency has improved several times, and can guarantee quality of product.
Embodiment
A kind of single-row bearing rollaway nest of thrust cone roller method for grinding comprises following process step:
After lathe adjusted to set angle,, adjust the angle of the lathe head of a bed and emery wheel again with the angle that the external diameter reconditioning of emery wheel becomes the tapered roller conical surface to set; Make the emery wheel wheel shaft become an angle of 90 degrees with workpiece spindle; The emery wheel external diameter is adjusted to the desired location on the workpiece, polishes, promptly get.
