摘要:

为减小堵塞度,严格控制某大型连续式跨声速风洞双转轴机构装备尺寸,研制出一种用于大负载双转轴机构的小体积、高扭矩、高传动精度的减速单元。通过对比分析渐开线行星、摆线针轮、谐波及蜗轮蜗杆传动等常用精密减速方式,提出了成熟摆线针轮RV传动与NGW行星传动串联组合的精密重载传动方式。基于ISO 6336、序列二次规划算法、有限元法对行星减速器进行优化设计及关键零部件强度分析,计算行星传动单元的回差与传动误差,对减速器进行了精度理论分析。其中,小齿隙行星传动加工及装配为其关键技术,突破了内齿圈及行星架精密加工、齿轮热处理变形控制与高精磨齿、整机复杂结构装配调整技术。研制专用试验台对该精密重载减速器进行传动性能测试,然后对其进行风洞验证,证明了所研制的减速单元满足某大型连续式跨声速风洞双转轴机构应用要求。

Abstract:

In order to reduce the degree of blockage, strictly control the equipment size of a large-scale continuous transsonic wind tunnel double rotating shaft mechanisms, a small volume, high torque and high transmission accuracy reduction unit for heavy duty double rotating shaft mechanisms was developed. By comparing the common precision deceleration methods such as involute planet, cycloid-pin, harmonic and worm gears, the precision heavy duty transmission method of RV and NGW planetary reducer in series combination was put forward. Optimization design of the planetary reducer and strength analysis of key components were conducted based on ISO 6336, sequential quadratic programming algorithm, and finite element method. The return difference and transmission errors of the planetary transmission unit were calculated, and precision theoretical analysis of the reducers was performed. Among them, the processing and assembly of small backlash planetary transmission were the key technology, breaking through the precision machining of internal gear ring and planetary carrier, gear heat treatment deformation control and high-precision grinding, as well as the whole complex structure assembly adjustment technology. The dedicated test rig was developed to evaluate the transmission performances of the current precision heavy duty reducer, followed by validation in the wind tunnel, confirming that the manufactured reduction unit meets the requirements for applications in a large continuous transonic wind tunnel double rotating shaft mechanisms.

Key words: wind tunnel, double rotating shaft, precision, heavy duty, RV reducer, planetary transmission
