Guangxi Diesel Generator Set Accessories Camshaft Maintenance

Guangxi diesel generator accessories camshaft maintenance includes camshaft, camshaft maintenance, maintenance of other parts of the three fields, the following by professional diesel generator manufacturer DingBo power for you to describe in detail.  

Engine camshaft shaft wear there are two ways to repair.  1 is pressed into the cylinder block bearing hole can be removed CAM bearings, and such a camshaft is relatively extensive, can be used to grind small motor shaft shape size and matched with the corresponding shape size of the CAM bearings.  Its maintenance dimensions are usually divided into four levels, each level reduced by 0.25mm(0.25mm, 0.50mm, 0.75mm, 1.00mm), usually in the CNC grinder.  The other is that the engine camshaft rotates directly in the cylinder block bearing hole, then the maintenance of the motor shaft, the application of chrome plating thick, and then grinding to the standard size or maintenance shape size and then match.

Camshaft surface such as strike mark, coarse and uneven wear, the application of engine camshaft special type CNC grinding machine repair, or according to the benchmark sample for delicate maintenance.  Camshaft height to width ratio due to wear down to the bottom limit (it can be the bottom limit decision in the thickness of the camshaft nitriding layer, usually not more than 0.50-0.80mm), should be in a special type of imitation machine tool or engine camshaft special CNC grinding machine light grinding.  

If worn out can do a good job of alloy electrode surfacing (such as the selection of general electrode, after welding to do a good job of nitriding and heat treatment process), then according to the sample to do a good job of light grinding, repair the original three-dimensional geometry.  In order to avoid thermal deformation during surfacing, the camshaft can be placed in water, and only part of the welding will leak out of the water.  Camshaft top with external thread, if the external thread is missing or does not meet the requirements, should be repaired.  

If there is any damage to the screw thread of the fixing nut of the camshaft of diesel generator, repair it by surfacing or replace it with a new one.  Timing gear key and keyway should be matched, if worn out, should be replaced with a new key.  When the tooth of driving gear of oil pump is worn out and its tooth loss exceeds 0.5mm, it should be repaired by surfacing welding.  When the eccentric wheel surface is worn out more than 0.5mm, it should be repaired.  When the chicken wing gear and camshaft are worn out too much or broken, the engine camshaft should be replaced.
