A kind of km silicon carbide abrasive and its preparation method and use method

Abstract

The invention provides a KM silicon carbide abrasive and its preparation method and use method. The abrasive comprises the following components: 5-30 parts of emery particles, 10-20 parts of white lead powder, 1-4 parts of calcium hydrogen phosphate, 20~40 parts of engine oil, 20~30 parts of linseed oil, 2~5 parts of sodium silicate, 32~37.99 parts of silicon carbide. The invention has high processing efficiency; little damage to the hard surface gear body; greatly shortens the running-in time of the newly assembled gear and the gear after repair; it is especially suitable for the point, line and surface grinding processing of the high-precision gear transmission line, and can effectively accelerate the grinding of the gear Meshing, reducing the influence of manufacturing and assembly errors on gear transmission, through online grinding processing, except for center moment deviation, pitting peeling, bearing damage, etc., the grinding process of meshing surface points, lines, and surfaces is fast and simple , easy to operate, easy to grasp, and suitable for popularization, which greatly improves the gear transmission accuracy and ensures the smooth production of new and repaired gears. It also has the advantages of no pollution, no influence on the quality of lubricating oil, greatly reducing the vibration frequency of the gear to the allowable range of the design, and no side effects.

Description

technical field [0001] The invention relates to the field of on-line processing of hard-faced gears, in particular to a KM silicon carbide abrasive and its production method and use method. Background technique [0002] Conventional hard-faced gears, due to their high hardness, are generally HRC58°~62°. After the gears are ground by the gear grinding machine, due to the processing accuracy of the equipment; Factors such as the displacement of the gear axis caused by the deformation of the parts in the process will cause the gear tooth surface to be stressed unevenly during the transmission process, which will inevitably cause a sharp increase in the vibration frequency during operation, which will easily cause damage to the motor, Accidents of reducers, driving wheels, and passive wheels have caused a high psychological burden on engineers and technicians. For large-scale equipment gears, it is not easy to disassemble. In order to avoid this disadvantage, the conventional m...

[0002] Conventional hard-faced gears, due to their high hardness, are generally HRC58°~62°. After the gears are ground by the gear grinding machine, due to the processing accuracy of the equipment; Factors such as the displacement of the gear axis caused by the deformation of the parts in the process will cause the gear tooth surface to be stressed unevenly during the transmission process, which will inevitably cause a sharp increase in the vibration frequency during operation, which will easily cause damage to the motor, The accidents of reducer, driving wheel and passive wheel caused a high psychological burden to engineers and technicians

For large-scale equipment gears, it is not easy to disassemble. In order to avoid this disadvantage, the conventional method can only use an electric grinder to install thousands of blades and manually grind them. This method is time-consuming and laborious, usually 10 to 15 days. Grinding requires extremely high levels of professional skills for operators; it is very difficult to manually make accurate judgments on abnormal working surfaces of gear meshing and processing; the grinding quality is very unstable due to human factors, and the tooth surface meshing is extremely uneven It will further aggravate the vibration of gears and cause serious accidents of broken teeth and gear scrapping, which directly affects the normal operation of the whole set of equipment
