Aligning device and aligning method for ball-filling gap of grinding bearing

Abstract

The invention relates to the field of manufacturing of deep groove ball bearings and angular contact ball bearings and provides an aligning device for a ball-filling gap of grinding bearing. The aligning device comprises a fixed seat, a column, a connecting block, a slide bar, a slide block, a rotating shaft, a measuring arm and a gap aligning sheet, wherein the column is fixed on the fixed seat, the connecting block is connected to the column and the slide bar, the slide block is arranged on the slide bar, the rotating shaft is further mounted on the slide block, the slide bar on the slide block is parallel to the rotating shaft in axis, the slide block can freely slide and rotate on the slide bar, the rotating shaft is fixedly connected to the measuring arm, and one end of the measuring arm is fixedly connected to the gap aligning sheet. According to the aligning device and the aligning method provided by the invention, locating grinding on a gap can be performed precisely and continuously, so that the grinding machining precision of the ball filling gap of the bearing is improved, the shape precision and the surface roughness of the gap are guarantee, the grinding gap defect is avoided, and meanwhile, the aligning device is simple in structure, convenient to use and low in cost, and the work efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of manufacturing deep groove ball bearings and angular contact ball bearings, in particular to an alignment device and an alignment method for grinding filling gaps of full complement deep groove ball bearings and angular contact ball bearings. Background technique [0002] Full complement deep groove ball bearings have ball openings on one side of the inner and outer rings of the bearing, so there are more steel balls that can be loaded, and compared with bearings with the same inner and outer diameters, they can withstand larger radial loads , especially suitable for parts on the aircraft body that need to bear a large load or similar special applications, and the market demand is large. However, the size accuracy and position accuracy of the ball filling gap are relatively high, and the processing is relatively difficult. At present, the current domestic processing methods are mainly milling processing or drilling ...

Problems solved by technology

However, the size accuracy and position accuracy of the ball filling gap are relatively high, and the processing is relatively difficult. At present, the current domestic processing methods are mainly milling processing or drilling processing, which cannot guarantee the processing requirements of high-precision bearings. The ball-filling notch is finished during grinding, and the shape accuracy and surface roughness of the arc-shaped notch radius R are guaranteed. In order to ensure that the grinding notch can meet the strict process requirements, the correct installation of the workpiece in the grinding fixture must be considered Location

If there is an error in the installation position, the gap after grinding will produce grinding defects such as "double eyelids", which not only affects the technical requirements of the product, but also has a negative impact on assembly
