在一辆T—54A坦克上安装了双圆弧齿轮侧减速器,行驶里程已达三千公里,并进行了爬坡和过各种障碍的特种试车,未发现异常情况。当完成七十公里工厂试车、一千公里保险期试车和三千公里试车时,均进行了分解鉴定。经观测:齿轮啮合正常、跑合良好、接触迹高于7级精度;齿面光亮、光洁度大大提高;齿面磨损较小(公法线长度的减小量在一千公里后为0.05mm,三千公里后累积为0.07mm);轴承良好,负荷最大而且承受轴向力的双排短圆柱向心推力轴承3522的径向间隙仍在出厂时合格的范围内,接触迹正常。复装后齿轮啮合响声较小,并继续试车考核。低速、重载的坦克测减速器,若采用双圆弧齿轮,将比渐开线齿轮的承载能力和使用寿命有大幅度的提高。
In a T-54A tank mounted double arc gear side reducer, mileage has reached three thousand kilometers, and carried out a variety of climbing and obstacles of special test run, did not find any anomalies. When the completion of the seventy kilometers of factory test drive, 1000 km test run and 3000 km test run, were decomposed appraisal. Observed: the gear meshing normally, run well, the contact trace is higher than the accuracy of 7; teeth bright, greatly improved finish; tooth surface wear is small (the reduction of the length of the common law after a thousand kilometers to 0.05mm, three After the kilometer mileage is 0.07mm), the radial clearance of the double row short cylindrical radial thrust bearing 3522 with good bearing, maximum load and axial force is still within the acceptable range of the factory and the contact trace is normal. After the gear meshing noise is smaller, and continue to test assessment. Low-speed, heavy-duty tank measured reducer, if the double arc gear, than the involute gear bearing capacity and service life has greatly improved.
