;The worm gear set is a spatial crossed axis transmission mechanism, compared to the cylindrical worm drive, the double-enveloping worm drive has the characteristics of higher contact ratio, higher transmission efficiency and larger load capacity. Since cylindrical worm drive have been widely used in industry, and there are relevant specifications for standard parameter design, but the double-enveloping worm drive does not have a clear design standard. The difficulty design of the parameters, production costs stay at a relative high level, and difficult control of precision, contribute to mass production is popular, and its advantages cannot be effectively utilized.
The purpose of this study is to analyze ZK-Type double enveloping worm gear set. Firstly, the mathematical model of worm gear set was developed based on the theory of gearing. Based on the relationship between the ZK-Type worm-type hob cutter and the conjugate tooth surface of the worm gear, the line contact of the conjugate gear set were discussed. In addition, in order to change the worm gear set from line contact to point contact, three methods were proposed on the worm gear tooth surface modified including tooth profile modification, lead modification, and double crowning modification. Finally, the contact paths, contact patterns and transmission errors were calculated by unloaded tooth contact analysis. The effects of assembly errors on the contact paths and contact patterns were also investigated and discussed.
