Nylon gear noise reducing measures

Nylon gear has been widely used in all kinds of machinery. It with belt drive, chain drive, worm drives have many advantages compared. For example:

Wide range of transmission speeds, transmission power, transmission reliability, compact, durable, can guarantee constant of instantaneous transmission ratio, but it's one of the disadvantages is noise. So, how to effectively reducing the noise of nylon gear sets, the author talking about the following:
1, select nylon gear parameters
When the nylon gear is selected, be conducive to reducing the noise of nylon gear. When choosing which tooth nylon gear should take the multi-tooth number as well. Namely: Center distance is confirmed, in the premise of meeting the bending fatigue strength, minimizing the modulus. Due to the d=MZ, when the nylon double spur gear pitch circle diameter d is constant, the smaller the modulus m, the number of teeth z more overlap coefficient is increased, thereby reducing the nylon gear driving noise. Meanwhile, modulus decreased nylon gear will cut processing costs. The other hand, when the nylon plastic gear is not reduced when the module, you should consider using oblique nylon gear, this can also increase the overlap factor, reducing the nylon gear driving noise. In oblique nylon gear for the choice of Helix angle is very high, because due to the smaller Helix angles, reflecting no advantages of oblique nylon gear, helical angle increases, corresponding to cause the increase of axial, so usually require between 8 ° ~20 ° Helix angle. In practical application, under the condition of small power transmission, spiral angle is slightly larger than a 16 °, so to reduce the noise effect is more obvious, and cannot lead to a considerable temperature rise (due to large spiral angle, axial force increase will make useless increases in temperature). Once again, our nylon gear set of general purpose standard pressure angle α = 20 °, but high speed nylon oil pump gear on the coincidence coefficient close to 2, addendum coefficient is recommended for 1~1.2, nylon gear pressure angle of 16 ° ~18 °, which can increase the flexibility of tooth, reduces the nylon gear fabrication driving noise.
2, the choice of materials
Gear materials such as carbon steel, forged steel, cast steel, cast iron and non-metallic materials (such as nylon, cloth and plastic). In order to reduce the noise of gear drive in certain strength requirements of the occasion, bold use of non-metallic material as gear of choice materials. Especially with the development of China's science and technology workers in research and development of non-metallic materials gradually, non-metallic materials part strength, accuracy will gradually increase, it will be increasingly favored by mechanical design workers. Meanwhile, in a pair of mesh nylon gear coupling sleeve, a gear with non-metallic materials, Metallic materials for other gear. Generally small gears made of nonmetallic and metallic materials for large gears, gear noise can be reduced.
3, Assembly
Quality large nylon gear driving noise. About use the same machines spinning nylon gear Assembly, will help reduce the noise of nylon gear meshing. Assembly pay particular attention to cleaning the nylon gear end of Burr, end Burr in the engaged directly in the process of noise, there are conditions to the tooth profile of intercropping reduce noise relief.
4, simulation runs
These measures still fall short of requirements, and unconditional renewal of the nylon gear coupling Machining accuracy when, running of the simulation is the most effective and inexpensive ways. Run time, mesh coated with abrasive paste and forward 10~20h, reverse the same amount of time. Run time be careful not to let the abrasive paste into the bearing area, so as not to cause bearing wear. To clean equipment after running, leaving no grinding paste and debris.
5, structure
Nylon gear trying to avoid the use of solid structure, and should be designed as a Web Panel structure. That is, as long as the strength to meet the requirements, nylon spiral bevel gears to minimize weight. This can reduce the natural frequency of the nylon gear, thus reducing the noise of mesh.
Without improving the precision of nylon gear reduced noise transmission
As we all know now the production of plastic nylon gear accuracy is generally not high, as well as in particularly serious noise during use, if deliberately choosing high-precision plastic nylon gear too highly uneconomical cost.
In short, the use of nylon pinion gear turns, in the nylon gear design, manufacture and installation should take a practical and effective approach, this nylon gear noise can be reduced. To improve working environment and health are of great significance. http://www.eilifen.com
