Improve the service life of GICL drum gear coupling

An important way to improve the service life of GICL drum gear couplings.The tooth width coefficient affects the tooth root bending strength and tooth surface contact strength of the tooth. The larger the tooth width coefficient, the greater the strength of these two items. The tooth width coefficient affects the coincidence degree. When the tooth width coefficient is less than a specific value, its value The increase of φ has a great influence on the increase of the coincidence degree, and when the value is greater than this specific value, the increase of the device value has a smaller effect on the increase of the coincidence degree. For the GICL-type drum gear coupling with a circular bulge curve, the tooth width It is still to determine the parameters of the bulge circle radius and backlash. The larger the tooth width, the larger the bulge circle radius and the larger the backlash required. Therefore, the following bright spot requirements are required:

1) When the inclination angle between the shafts is large, there will be no edge contact phenomenon;

2) The smaller the gear tooth concentrated load, the better, and the curvature of the tooth surface is proportional to the circumference of the drum, so the drum radius is as large as possible.The curvature radius of the bulge curve is proportional to the single-sided thinning of the internal tooth, so the bulge circle radius should be as large as possible.The radius of curvature of the drum curve is proportional to the single-sided thinning of the internal tooth, that is, it is related to the meshing gap of the tooth. Insufficient thinning may cause interference, and excessive thinning will weaken the strength of the tooth, and the backlash will be large. .

High-speed GICL-type drum gear couplings are usually lubricated with lubricating oil. The tooth surface requires continuous lubrication. The lubricating oil should be drained smoothly, otherwise the temperature of the tooth surface will rise and accumulate moisture and dirt. The lubricating oil needs to be filtered by an oil filter. , The filtration degree is less than 10 microns. Some important high-speed GICL-type drum gear couplings can also adopt the structure of oil collecting grooves, that is, the oil collecting grooves are machined in the shaft hole of the external gear, and the grooves are drilled at the bottom of the tooth groove of the external gear. The oil holes connected to the oil collecting groove use the centrifugal force generated by the high-speed operation of the GICL drum gear coupling to spray oil into the meshing part of the inner and outer teeth to make it sufficiently lubricated.

The localization and independent research of wind turbines is an urgent problem that my country needs to solve. Usually, wind power equipment has to operate in the field for more than XNUMX years and has to withstand the test of complex weather conditions and wind changes. Therefore, the quality of wind power equipment requires strict requirements.Coupling is a particularly important part of wind turbines. However, its design and manufacturing have always been a problem that plagues technical personnel. At present, there is no manufacturer of coupling parts in our country, and all rely on them. Therefore, there is only one solution to the coupling. It is difficult to design and research to realize the mass production and research of domestically produced large-scale wind turbines.The more important thing in the research and design of the coupling is to determine that it has sufficient strength and rigidity. Therefore, it is very important to calculate and check the strength and rigidity of the coupling.

Wind power generation converts the kinetic energy of the wind into mechanical energy, and then converts the mechanical energy into electrical energy. The basic principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the rotation speed through a speed increaser to promote the generator to generate electricity.Household electricity generally uses single-run small wind turbines and batteries.Production electricity usually uses medium and large wind turbines and grid-connected operation of public grids. It can also be combined with diesel generators to form a system for switching operation, grid-connected operation or parallel operation, and output AC power. Many wind power has good environmental benefits and no emissions The outstanding advantages of arbitrary waste and harmful gases, and it is also a very low-priced renewable energy technology, which costs only 4 to 6 cents per kilowatt hour, and the construction cost of wind power plants is also higher than that of thermal power stations and hydropower stations. Compared with other forms of energy generation in nuclear power plants, wind power generation does not require raw materials, and there is no additional consumption other than normal overhaul and maintenance.Although wind power generators make noise during wind power generation, windy places are often wastelands or grasslands with fewer residents nearby, and the construction of wind farms also creates local tourism resources.my country has built a large number of wind power generation facilities on the grasslands of Inner Mongolia, and the technology has improved day by day, and the production cost has also been reduced.Wind power generation also has corresponding shortcomings. In some areas, due to terrain and other reasons, wind energy varies greatly, the wind is intermittent, and the distribution is also very uneven. The worse the situation is, such as Taiwan and other places that require better summer and daytime. Electricity, but the wind is less at this time. Therefore, in order to make the user's power supply stable and sufficient, wind turbines can complement solar cells. When the wind is strong and the sun is weak, wind power is the mainstay, and photovoltaics are the auxiliary; When the weather is clear and the wind is low, photovoltaics are the mainstay, and wind power is a supplement.
