升级本田叶轮到定子轴承

Torque converter rebuilders have been reporting Honda bearing failures in increasing numbers. The bearing failures have been from different locations within the converters and have been reported in most Honda and Acura models. The most common of the failures has been the bearing located between the impeller and stator in thelarger diameter converters。在所有转换器中，当车辆加速时，该位置的轴承携带大部分推力负荷，并且通常是最失效的第一轴承。由于较大的直径转换器用于较大的扭矩V6应用中，因此该轴承上的推力负载甚至更大。

在失败的轴承上完成的根本原因分析发现，尽管轴承上的推力负荷是一个因素，但它不是轴承故障的主要原因。本申请的OE HONDA轴承是露面轴承（HO-N-6）使用法兰叶轮轮毂的推力表面作为其轴承比片之一。叶轮轮毂图1是典型的啊f a failed unit.

在失败转换器中的叶轮集线器的紧密检查产生了几个关于故障的线索。过热引起的明显变色是第一个线索。土豆芯片磨损图案是第二线索，延伸圆周整个长度的磨损图案是第三线索。由于本田转换器众所周知，由于其过热问题，因此可以轻松跳到结论，即转换器过热地耗尽叶轮轮毂的轴承表面并导致轴承失效。过热以变为蓝色的转换器已经足够热，以改变金属的脾气。检查这种表面的硬度似乎备份了这个假设。轴承赛的正常硬度应在58-60罗克韦尔范围内，并且该叶轮毂的轴承表面在一个点处低至50个罗克韦尔。

虽然过热问题仍然是导致脾气失利的好候选人，但这不是唯一的可能性。这个单位的集线器不是原创的，而是一个替代品。现在问题变得越来越多：转换器是否过热，以影响更换中心的硬度，或者在安装焊接过程中是替换中心的轴承表面的脾气何处？在焊接过程之前和之后测试叶轮轮毂轴承表面的硬度是必要的，以回答这个问题。

维珍替代叶轮轮毂的轴承表面（ho - 90 - 4 g）经过测试并落在58-60罗克韦尔范围内。然后将叶轮轮毂焊接到叶轮中，并且硬度被重新测试。从焊缝开始并继续持续约75％的焊缝的持续时间，硬度仍然在58-60洛克韦尔范围内。在焊缝的最后25％附近测量的硬度是不同的故事。在该领域，硬度在10克尔韦尔和浸到50罗克韦尔的一点时变化。第二个硬度测试的结果导致了几个结论。一个是轴承表面的整个圆周处的磨损图1was probably caused by the loss of temper during the weld process, and that the potato chip distortion also was caused by the same heat. A second conclusion was that Honda had recognized this issue and addressed it by using a two-headed welder to install all of its impeller hubs (see图2）。

The third conclusion was that it was either time to invest in a two-headed welder or source a suitable enclosed bearing to replace the Honda OE bearing. Since two-headed welders are very expensive, the enclosed bearing seemed to be the better choice.

轴承（JA-N-13）在大多数情况下在定子和叶轮之间找到RE5R05Aconverters is a good replacement bearing (图3.）。It is very robust, and dimensionally it is ideal for the application. It is .035" larger in diameter than the cavity where the OE bearing and wear plate live, so a minimal clean up of the bore is all that is necessary to fit the bearing into the stator (图4.）。继续将加工过程延续到孔的底部将为良好的轴承寿命提供大量润滑油。成品看起来像图5.。

Another plus of using this bearing is that it is about .040" thicker than the combined thickness of the OE bearing and wear plate. This extra thickness allows you to either clean up the wear on the OE impeller hub or remove the potato chip distortion of the replacement hub caused by the welding process.
