Bearing in daily life use, need to pay careful attention to its use, let’s look at the nine things we need to pay attention to.

1. the riveting parts of the harvester such as the knife assembly, rivets are generally made of cold extrusion, in the riveting should not be heated, such as heating will reduce the strength of the material. After riveting, the forming punch is applied to strengthen the fastness of the blade and the tool rod.

2. vulnerable parts, especially the pin shaft, press, sleeve, pad iron in the maintenance can not be replaced by more butter and repair, such as long time use wear to the limit of parts will cause the reduction of other mechanical life.

3. no balancing machine shaft repair in repair all kinds of shaft to balance, can be installed at one end of the shaft with a thrust bearing, clamping on the lathe claw, the other end can be used to stand on the top, such as lathe short, available center frame clamp the other end of the SKF bearing mounted on the shaft, calibration balance. But in the counterweight, tighten with screws, try not to use welding counterweight.

4. In maintenance, due to the variety of bearing materials, it is not easy to purchase. At present, most of the used shafts in China are made of 45# carbon steel.

5.in the processing of sleeve parts as far as possible in the sleeve hole in the oil groove because of some parts of the harvester refueling is very difficult, where it is difficult to refueling butter and heavy oil, except nylon sleeve. Where the nylon sleeve is used, it is best not to use cast iron, copper, aluminum instead, because the nylon sleeve bears a certain impact without deformation.

6. key and keyway on the shaft, pulley, and repair shall ensure that the size is not in advance, could not increase the size of the key, otherwise it will affect the strength of the shaft, shaft keyway available welding filler repair welding in the opposite direction to the old key a keyway milling, pulley keyway on the set of available (transition fit), with good after use countersunk screw tapping to tighten the plug button in the set of seam.

7. The maintenance of the hydraulic part of the harvester is to unload the distributor and the flow reduction valve, etc., and use the air pump to pressure the pipe fittings. When the hydraulic oil is loaded twice, it should be filtered and exhausted.
