Abstract

The invention discloses an electrochemical machining device and method for an internally-oblique micro line segment gear. The electrochemical machining device comprises a power system, a PLC control system, an electrolyte circulating filtration system, a numerical control rotary table, a cathode system and a workpiece clamp. According to the method, a sheet-shaped cathode which is machined by a high-precision linear cutting machine and has the thickness of 1mm is used, and the gear outline shape on a tool cathode is obtained by the fact that a workpiece inner gear shape to be machined and formed is offset to the inner side by a machining gap delta in the radial direction; in the machining process, the tool cathode makes rotating movement around a shaft while being fed downwards in the radial direction, and workpieces are machined according to an electrochemical anodic dissolution principle; the spiral angle of an inner gear is guaranteed by the speed ratio of axial feeding and rotary feeding around the shaft, and when the spiral angle of the gear is changed, corresponding angle machining can be achieved through change of the speed ratio of the axial feeding and the rotating movement around the shaft. The electrochemical machining device and method are beneficial to improving the machining efficiency and the gear forming precision.

Description

technical field [0001] The invention belongs to the technical field of special machining, and in particular relates to an electrolytic machining device and method for internally inclined micro-segment gears. Background technique [0002] Micro-segment gear is a new type of gear invented in recent years. Its tooth profile curve is composed of micro-segments, which is similar to a curve of stepped circular arc tooth profile. High efficiency, small temperature rise and so on. The research shows that micro-segment gears have high bending strength and contact strength, and the minimum number of teeth is small (3~4 teeth), which can well meet the all-round requirements of modern industry for gear transmission performance, especially for high-speed, heavy-duty gears. and miniaturization requirements. The high-precision, high-efficiency and stable manufacturing of micro-segment gears has become a key problem to be solved in the field of manufacturing and processing. Internally in...
