How to repair the eccentric shaft jaw crusher?

HJ Series Jaw Crusher is used very widely in national economic construction. In the operation process, because the axis neck circle loss, often appear eccentric shaft failure problems, affect the normal operation, so need to promptly to the eccentric shaft failure repair. The eccentric shaft repair can lose round view from shaft neck to complete correction. Fixed axis neck circle loss can be welded surfacing method and brush plating method two.

welding method

Welding is one of the effective methods to modify the eccentric shaft neck, welding method is broken shaft neck wear surfacing machine must thickness in the jaw, and then machining fine car in place. Simple way of heating surfacing wear parts, without special equipment, but the quality of the welding quality, and the use is not the best, the reason is that when welding thermal stress. The correction process is:

The shaft in Lathe will remove rear axle neck car wear small 5~10m. Also can not directly welding car.

The oil stain cleaning shaft neck clean

The surfacing positions and adjacent parts of heating. There are two kinds of heating methods. One is around the neck circumference heating with oxygen torch, shaft can be supported on a roller top roll, so that the entire circumference temperature near unanimous. Another is the copper wire winding temperature in the shaft ends. The heating temperature of the two methods should reach 750 degrees celsius. Welding in a thermal state, the intent is to ensure the welding quality and future cutting quality.

brush plating mending method

The process of brush plating skills revision shaft are as follows:

The brush plating before the shaft neck appearance with TGY-1 activated liquid energized by electrochemical treatment, obtains the wedge surface cleaning.

The axle clamp TDY-102 on lathe (with thimble as skill based standard) as the slow rotation.

The tooth brush plating pen wrapped cotton, with the rapid solution of nickel and workpiece touch, and relative motion, the metal ion in the solution under the electric field effect to job relocation after discharge, appearance, crystal deposition in the Journal on the surface, forming a solid coating.

Brush plating skills with modified shaft neck uniform coating thickness, coating and base metal contact strength and other physical and chemical target arrives at the rules demand, because the coating surface is clean, without further grinding. The biggest flaw brush plating skills is a must have for brush plating machine.

Both surfacing method is still brush plating modified eccentric shaft, can greatly save steel, reduce repair costs, at the same time shorten repair time, create conditions for the normal production of crusher.
