徐州INA轴承NKI12/20农具旋耕机损坏的观察分析

徐州INA轴承万向节损坏是旋耕机作业中常见的问题。在大多数情况下，轴承疲劳损伤会导致轴承疲劳损伤。一般来说，轴承疲劳损伤造成的损伤只有三分之一来自润滑不顺畅，三分之一来自污染物进入轴承或安装和处理不当。然而，这些类型的损坏都是与工业轴承无关的精*密零件，所以在使用高性能轴承时要小心，即使使用不当，也不能达到预期的性能效果，而且容易造成轴承损坏。据调查，造成旋耕机万向节损坏的主要原因是：使用不当、安装不正确、万向节轴和套筒选用不当、未按规定及时***、等待提升和强制旋转时转动刀头或不上升。

Damage of universal joint of Xuzhou INA bearing is a common problem in rotary tiller operation. In most cases, bearing fatigue damage will lead to bearing fatigue damage. Generally speaking, only one third of the damage caused by bearing fatigue damage comes from poor lubrication, and one third comes from the incorrect entry of pollutants into the bearing or the improper installation and treatment. However, these types of damages are precise * compact parts unrelated to industrial bearings, so be careful when using high-performance bearings, even if used improperly, can not achieve the desired performance results, and easy to cause bearing damage. According to the investigation, the main reas*** for the damage of the universal joints of rotary tillers are: improper use, incorrect installation, improper selection of universal joints axles and sleeves, failure to maintain in time according to regulati***, turning the knife head or not rising while waiting for lifting and forced rotation.

防止徐州INA轴承旋耕机万向节损坏的措施如下：

Measures to prevent damage of cardan joint of Xuzhou INA bearing rotary tiller are as follows:

旋耕机不应在多石的土地上使用。应使用其余农具。

Rotary tillers should not be used on stony land. The rest of the farm tools should be used.

首先采用动力组合，然后缓慢降低农具，使旋耕机的叶片提前缓慢落入土壤中。

Firstly, the power combination is adopted, then the farm tools are slowly lowered, so that the blades of the rotary tiller fall into the soil slowly in advance.

万向节的方轴和套筒长度应与农具类型相匹配。如果太长，使用中会损坏变速器零件。如果太短的话，农具在被提起时就会出来。

The square axis and sleeve length of universal joint should be matched with the type of farm tools. If it is too long, tran***ission parts will be damaged in use. If it is too short, the farm tools will come out when they are lifted.

万向节安装时拨叉开口应在同一*平面上，以保证刀轴徐州INA轴承的旋转力均匀，否则容易损坏传动部件。

When the universal joint is installed, the opening of the dialing fork should be on the same * plane to ensure that the rotation force of the Xuzhou INA bearing of the cutter shaft is uniform, otherwise the tran***ission parts will be easily damaged.

润滑***应按要求按时进行。为了防止干摩擦造成的早期损坏，所有润滑点不应省略喷油和注脂。

Lubrication maintenance should be carried out on time as required. In order to prevent early damage caused by dry friction, oil injection and grease injection should not be omitted at all lubrication points.

农具提升高度由液压控制，旋耕机提升高度不大于20。

The lifting height of farm tools is controlled by hydraulic pressure, and the lifting height of rotary tiller is not more than 20.

转动时，徐州INA轴承**须先将农具吊起，否则容易损坏传动部件。

When turning, the INA bearing in Xuzhou must be lifted first, otherwise the tran***ission parts will be damaged easily.

在工作中，万向节方轴与传动平面的夹角不应超过10度，否则会降低传动效率。农具吊装后角度不宜超过30度，否则易损坏万向节。轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。当识别轴承的真实性时，通过触摸轴承上的钢印来识别轴承的真实性是更快、更准确的。这种***如果用手触摸就没有接触，但用钉子轻轻地触摸徐州INA轴承就可以感觉到。

In the work, the angle between the universal joint square shaft and the tran***ission plane should not exceed 10 degrees, otherwise the tran***ission efficiency will be reduced. The angle of farm tools should not exceed 30 degrees after hoisting, otherwise the universal joint will be easily damaged. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When recognizing the authenticity of bearings, it is faster and more accurate to recognize the authenticity of bearings by touching the steel stamps on bearings. This stamp has no contact if it is touched by hand, but it can be felt by touching Xuzhou INA bearing gently with a nail.
