Embodiment 1

[0031] A low-cost and high-efficiency machining method for a cycloidal gear, comprising the following process steps:

[0032] (1) Select No. 45 steel round billet with better comprehensive mechanical properties as the raw material;

[0033] (2) Normalizing: heat to 920°C, hold for 1 hour, quickly cool to 600°C, hold for 1 hour, take it out of the furnace and cool in the air;

[0034] (3) Carry out bearing hole 1 processing on the round billet after normalizing treatment, and then carry out broaching processing on the billet with the bearing hole 1 positioned to obtain a cycloidal 3-tooth shape (such as figure 2 shown);

[0035] (4) Phosphate and saponify the billet after broaching in the phosphating solution and saponification solution. The components of the phosphating solution are: zinc dihydrogen phosphate 60 g / l and zinc nitrate 110 g / l, The temperature of the solution is 70°C. Wash the pickled workpiece with water and put it into the prepared phosphating solution for p...

Abstract

The invention relates to a low-cost and high-efficiency machining method for cycloid gears. The method is characterized by comprising the following process steps that (1) round metal billets are selected as raw materials; (2) the round billets are subjected to normalizing treatment; (3) the round billets are subjected to gear broaching; (4) the billets are subjected to phosphating and saponifying treatment in sequence; (5) the billets are subjected to oil film lubrication and extrusion machining; (6) annealing is carried out; (7) the step (4) and (5) are repeated; (8) auxiliary holes of the billets are machined with a cycloid as the benchmark; (9) quenching treatment is carried out; (10) tempering treatment is carried out; (11) workpieces are subjected to finishing machining; and (12) polishing treatment is carried out. According to the method, the cycloid gears are subjected to extrusion machining for two times through the oil film lubrication and extrusion technology; the cycloid gears are subjected to polishing treatment through abrasive flow machining technology; the machined cycloid gears are low in surface roughness and high in dimensional accuracy; and the machining efficiency of the cycloid gears is remarkably improved, and the machining cost is reduced.
