Abstract

本实用新型涉及一种用于机械传动中的弧形齿圆柱齿轮。弧形齿圆柱齿轮与传统的各种圆柱齿轮不同之处是该齿轮的齿在齿轮圆柱表面上呈弧线排列,而不是呈直线排列。
弧形齿圆柱齿轮与直齿圆柱齿轮,斜齿圆柱齿轮和人字齿圆柱齿轮相比较,其主要优点为:传动中重合系数大,啮合平稳,没有轴向力,传动效率高,可连续范成加工,切齿工艺简单,能达到较高精度。

Description

本实用新型涉及到一种用于机械传动中的弧形齿园柱齿轮。
齿轮在机械传动中是应用最广的零件之一。传递平行轴之间转动的齿轮为直齿园柱齿轮、斜齿园柱齿轮和人字齿园柱齿轮,由于这些园柱齿轮的齿在园柱表面上是呈直线(或斜直线)排列的,因而它们都存在一些难以克服的缺点。如直齿园柱齿轮重合系数小,传动平稳性差,承载能力较低;斜齿园柱齿轮会产生轴向力,影响传动效率;人字齿园柱齿轮结构复杂,加工困难。为克服园柱齿轮的这些缺点,特提出本实用新型--弧形齿园柱齿轮。
弧形齿园柱齿轮与直齿园柱齿轮、斜齿园柱齿轮和人字齿园柱齿轮不同之处在于该齿轮的齿在园柱表面上是呈弧线排列的,而后者是呈直线排列的。至于弧形齿园柱齿轮的齿廓曲线,在法向断面上,与一般园柱齿轮是相同的,即可以是渐开线也可以是摆线或园弧曲线等。
弧形齿园柱齿轮的特点是:与直齿园柱齿轮相比,它的重合系数较大,因而啮合平稳性好,传递载荷较大;与斜齿园柱齿轮相比,它不产生轴向力,因而传动效率较高;与人字齿园柱齿轮相比,它的加工方法大为简化,可以用园盘铣削头连续范成加工,切齿工艺简单,加工效率高,且能达到较高的精度。此外,由于弧形齿园柱齿轮的齿在园柱表面上呈弧线排列,它与呈直线排列的园柱齿轮相比,在齿轮宽度相同的情况下,它的一双齿的接触线就更长,这对提高齿轮的承载能力和传动平稳性也是有利的。
下面对附图进行说明。
附图为本实用新型的外观立体图。其中〔1〕为呈弧线形排列在园柱表面上的齿。
应用范成法即可加工出本实用新型所称的弧形齿园柱齿轮。
