Chongqing Xiexiang Machinery Manufacturing Co., Ltd. specializes in the production of crankshaft pins. We have many different problems in the use of crankshaft pins. What are the inspections for crankshaft pin damage?

1. Use outside micrometer for wear.

2. Inspection of cracks

(1) Oil seepage tapping method: soak the cleaned crankshaft pin in kerosene, take out the crankshaft pin and wipe it clean, sprinkle white powder on the surface, and then tap the crankshaft pin non-working surface along the shaft pin with a hand hammer. If there are obvious crack-like oil marks in the white powder, there are cracks.

(2) magnetic flaw detection method: with the aid of a flaw detector to magnetize the parts, and sprinkle some magnetic powder at the parts where cracks may occur. When the magnetic lines of force pass through the edge of the crack, the magnetic powder will be adsorbed at the crack, thus showing the location and size of the crack.

I hope today's analysis can have a reference for the majority of motorcycle enthusiasts!

Repair of Cracks in Crampins

Chongqing Xiexiang Machinery Manufacturing Co., Ltd. is a company focusing on the production and sales of crankshaft pin. It is a crankshaft pin factory in Chongqing, a crankshaft pin manufacturer in Chongqing and a crankshaft pin company in Chongqing. We stand in a very professional point of view to analyze how to repair the crack of the crank pin. If the crack occurs in the non-stressed position or the crack does not extend, it can be repaired. Crank pin cracks in the pin shank arm and pin neck and other stress parts, should be replaced with new parts. Therefore, our crankshaft pin is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance.

Repair of crank pin of motorcycle

As a motorcycle crankshaft industry research for more than ten years of small series, has long known that the production of the crankshaft is a high technical accuracy of the work, then how to repair the crankpin? First of all, we analyze the crankshaft pin fineness, crankshaft journal roundness and cylindricity error of more than 0.01~0.0125mm, should be in a special crankshaft pin grinding machine for grinding. Crankshaft pin radial runout, generally not more than 0.04~0.06mm. If it exceeds 0.10mm, it needs to be corrected.
