收割机中的铆钉，如移动刀组件和铆钉，通常由冷挤压制成。铆接不能加热。如果加热，材料的强度会降低。铆接徐州NSK轴承后，采用成形冲头强化刀片和刀杆的硬度。

Rivets in harvesters, such as moving knife assemblies and rivets, are usually made by cold extrusion. Riveting cannot be heated. If heated, the strength of the material will decrease. After riveting Xuzhou NSK bearing, the hardness of blade and tool rod is strengthened by forming punch.

易碎部件，尤其是销、片、套和垫圈

Fragile parts, especially pins, sheets, sleeves and gaskets

在维修过程中，不可能用更多的黄油代替更换和修理。如果零件长期磨损到极限，则会缩短其余机器的使用寿命。

During the maintenance process, it is impossible to replace replacement and repair with more butter. If the parts are worn to the limit for a long time, the service life of other machines will be shortened.

在修理各种没有平衡器的车轴时，止推徐州NSK轴承可以安装在车轴的一端，夹在车床的三个爪子上，另一端由顶部支撑。如果车床短，轴另一端的轴承可由中*心框架夹紧以校正平衡。但在称重时，拧紧螺丝，尽量不要使用焊*接称重。

When repairing various axles without balancers, the thrust Xuzhou NSK bearing can be instalLED at one end of the axle, clamped on three claws of the lathe, and the other end is supported by the top. If the lathe is short, the bearings at the other end of the shaft can be clamped by the central frame to correct the balance. But when weighing, tighten the screw and try not to use welding joint weighing.

在维修方面，购买进口轴承材料并不容易。目前，我国大多数车轴都采用废旧车轴进行加工。如果需要淬火和回火，氧气和陶炉可以按要求加热到洪中武，并在苛刻条件下置于盐水中。

In terms of maintenance, it is not easy to purchase imported bearing materials. At present, most axles in our country are processed with waste axles. If quenching and tempering are required, oxygen and pottery furnaces can be heated to Hongzhongwu as required and placed in Brine under harsh conditions.

加工套筒零件时，尽量拉动徐州NSK轴承套筒孔内的油槽。

When processing sleeve parts, pull the oil groove in the sleeve hole of Xuzhou NSK bearing as far as possible.

因为给收割机的一些部件加油非常困难，所以除了尼龙套筒之外，任何难以加油的地方都可以使用黄油和重油。代替尼龙套筒零件，**好不要用铸铁、铜、铝代替，因为尼龙套筒承受一定的冲击而不变形。

Because it is very difficult to refuel some parts of the harvester, butter and heavy oil can be used wherever it is difficult to refuel, except for nylon sleeves. Instead of nylon sleeve parts, ** do not use cast iron, copper, aluminum instead, because the nylon sleeve bears a certain imPACt and does not deform.

轮轴键槽的修理

Repair of Wheel Shaft Keyway

车轴上的键槽可以用焊*接填料修补，这样徐州NSK轴承键槽就可以在旧键槽相反的方向上铣削。滑轮上的键槽可以通过插入来设置。插入后，可通过轻敲插座中的沉头螺钉来拧紧键槽。

The keyway on the axle can be repaired by welding filler, so that the keyway of Xuzhou NSK bearing can be milled in the opposite direction of the old keyway. The keyway on the pulley can be set by insertion. After insertion, the keyway can be tightened by tapping the countersunk head screw in the socket.

收割机的液压部分、卸载分配器和安*全阀应由空气泵维护，以冲洗管道压力。液压油在二次装载时应过滤并排出。卸货后应更换密封件。

The hydraulic part of the harvester, the unloading distributor and the safety valve shall be maintained by an air pump to flush the pipe pressure. Hydraulic oil should be filtered and discharged during secondary loading. Seals should be replaced after unloading.
