Embodiment Construction

[0010] The non-integral circular track thrust ball bearing provided by the present invention includes equally divided sector blocks 4, 5 or horizontal and vertical cutting blocks ( Figure 4 ), positioning pin 1, screw 3, steel ball cage 6, high-strength wear-resistant adhesive 2 and other parts. Each equalized fan-shaped block or horizontal and vertical cutting block of the present invention is forged with bearing material GCr15, and assembled on the assembled track base surface of the vertical lathe base and the track base surface of the vertical lathe workbench after processing, and the assembly process belongs to the known technology , so no explanation is given. Form a circle composed of multiple equally divided fan-shaped blocks or horizontal and vertical cutting blocks, and then carry out CNC cutting and machining of the track. After the processing is completed, disassemble each block for heat treatment, and then assemble it to the base surface , Fill the gap with high-...

Abstract

A thrust ball bearing for a vertical lathe workbench mainly reflects in a non-integral ball track circle. The thrust ball bearing comprises equant sector blocks or horizontal perpendicular cutting blocks, a positioning pin, a screw, a steel ball retainer and a high-strength wear-resistant adhesive for filling gaps. Processed equant sector blocks or horizontal perpendicular cutting blocks are installed on a processed basal plane of a vertical lathe seat assembly rail and on a basal plane of a vertical lathe workbench assembly rail. Steel balls with different specifications and a steel ball retainer for a rolling bearing are provided according to actual need, and the non-integral rail thrust ball bearing can be applied to the vertical lathe immediately. The invention has the advantages of simple structure, convenient maintenance, low cost, and high precision reaching or exceeding the national precision requirement on vertical lathe workbench.

Description

technical field [0001] The invention relates to the mechanical equipment manufacturing industry, in particular to a vertical lathe in the machine tool industry. Background technique [0002] Thrust ball bearings are the basic parts of the mechanical equipment manufacturing industry and are national standard parts. However, there are certain limitations in the application of vertical lathes as workbench supporting thrust rotating parts, especially in the case of larger diameters, the difficulty of manufacturing and installation is more prominent. Bearing material GCr15 is difficult to achieve in forging and heat treatment, and has to be replaced by other materials, which affects the service life of the bearing. Usually, the vertical lathe table rotates with hydrostatic bearings, whose running accuracy can only meet the general requirements, and the structure is complex, and installation and maintenance are inconvenient. Contents of the invention [0003] The object of the...
