Ingeniously repairing the worn-out bearing housing hole The bearing housing hole has been worn out by the bearing “outer ring†(set) and can be repaired by the following method.
1 dozens of powder coating method: the worn hole of the hole, evenly beaten with a sharp point in the wear and tear, the wear and tear should be deep, and the wear and tear should be shallow. Then, the grinding wheel powder (iron filings) which are usually polished by the grinder is blended with the butter in equal parts, and evenly stirred and applied to the surface of the perforated bearing hole. Its thickness and thickness should be determined according to the degree of looseness. In addition, the bearing seat is at the mouth. Due to the rotation of the bearing "outer ring", the edge of the "outer ring" of the bearing is also ground, which needs to be flattened with a wedge, and then padded with a suitable copper or other circle at the "stop".
2 Dot sparking method: use a secondary line of the battery to connect to the object to be hit (bearing hole sleeve or outer ring of bearing), and the other wire is connected with carbon rod or spot welding with aluminum wire (punching). Experience has learned that with the above two methods, the effect is very good, especially the first method is more simple and easy.
The reasons for the oil seal leakage and the oil seal leakage are: 1 the oil seal itself is broken and the spring of the oil seal is slack.
2 The amount of axial forward and backward movement is large, so-called shifting pump oil.
Cooperate with the over-tight parts to take the original interference fit parts of the car. In the use, due to deformation, rust or lack of special tools during the repair, such as "axis" embedded "set"; bearing "outer ring" jacket With the "seat hole" and the engine front timing wheel, the "shaft and gear" that is too tight in the transmission.
Deep Hole Coolant Thorugh Drill
Advantages for the deep hole carbide drill:
1. Optimized groove geometry design. These cemented carbide deep hole drills have advanced groove geometry design to optimize chip removal from deep in a wide range of material holes;
2. The shape of Dahua coolant pipeline. In order to provide a better coolant supply to the cutting edge, the tool has a larger coolant pipe profile, which ensures an effective coolant supply to the cutting edge and chip removal;
