摘要

在具有加工和安装误差的情况下

为了研究各蜗杆参数对无侧隙双滚子包络环面蜗杆的齿廓及蜗杆齿面接触线的影响规律

建立了包含加工误差和安装误差的蜗杆传动啮合函数

建立了蜗杆齿面接触线及蜗杆齿廓方程

利用三维建模技术分析了蜗杆、蜗轮轴交角误差

中心距误差

蜗杆轴向窜动误差

蜗轮滚子齿距角误差

砂轮滚子偏距误差

转角误差等对蜗杆齿廓的影响

同时分析了在误差作用下蜗杆齿面接触线发生的变化

并进行了运动学仿真.研究结果表明:转角误差、砂轮滚子齿距角误差达0.5°时对蜗杆齿廓影响较为明显

即容易产生卡死现象;当蜗杆轴交角误差达0.5°时

整个蜗杆齿廓产生了严重变形

且蜗杆轴断面变为椭圆形

极易发生蜗轮轮齿折断现象;其他误差在1 mm以内时对齿廓及齿接触线的影响较小.

Abstract

For a new non-backlash double-roller enveloping hourglass worm

the tooth profile and contact curve equation

which involves several errors of worm parameters

was established to investigate the effects of the errors on the worm tooth profile. Technology of three-dimensional modeling was chosen to analyze the influence law of the errors. The influences of the setover error of roller

the error of axial float of worm

the centre distance error

the error of axial movement

the angular pitch error and the error of shaft angle on the tooth profile were discussed

the contact curve was analyzed

and the kinematic simulation was carried out. The results show that the axial movement error

the angular pitch error and the error of shaft angle reaching 0.5° exert clear influence on the tooth profile of worm; especially

when the error of shaft angle gets 0.5° the tooth profile of worm is heavily deformed and the axis cross-section becomes ellipse; however

the other errors have lighter influence on the tooth profile of worm as the values are limited within 1.0 mm.
