Problems solved by technology

However, the steel plate stamping corrugated cage uses stamping to process the pockets. Due to its thin thickness, poor wear resistance and impact resistance, it can only be used in occasions with low speed and stable load.
The engineering plastic cage is formed by injection molding. Due to its poor dimensional stability, large thermal expansion, low strength, and poor heat resistance, it can only be used in occasions with low speed and stable load.

Embodiment Construction

[0015] The present invention is a brass or bronze cage. The specific processing steps are as follows: According to the traditional method, the blank is cut off by a lathe for outer diameter, inner diameter, and turning end, and then processed into a single half-piece annular cage, and the outer diameter is softly ground, and the inner diameter is finely turned. After positioning the inner diameter and end face of the single half-piece annular cage 1 through the support plate 2 and the pressure plate 3, use the compression screw 6 to axially compress, and the machine tool automatically selects the spindle speed and feed rate according to the program. Use the spherical milling cutter 5 from the end face The direction is along the axial direction, and the plunge-cut milling first roughs out the shape of the spherical pocket, and then uses the fine milling cutter to process the required spherical size and shape tolerance. After the milling of the hemispherical pocket hole is compl...

Abstract

This holder process technology is once positioning, processing step of half-ball hole, rivet hole. It is ensuring the changable and raising processing precision.

Description

Technical field [0001] The invention belongs to the technical field of processing bearing cages, and mainly relates to a processing method for spherical pocket cages of deep groove ball bearings. Background technique [0002] There are three main types of known deep groove ball bearing cages: car-made brass or bronze two-half cages, steel stamping corrugated cages, and engineering plastic cages. Car-made brass or bronze two-half cages are mainly suitable for bearings with an inner diameter greater than 200mm, high speed, heavy loads, and impact loads. Since the shape of the pocket of this cage is cylindrical, the guiding method is the outer ring or The ribs of the inner ring are guided, resulting in a small guide gap, and it is difficult for the lubricating medium to enter. In addition, the radial movement of the cage is large. When running at high speed, the ribs of the ferrule are likely to rub against the outer diameter or inner diameter of the cage, wear and generate hea...
