Drum gear coupling warranty

　　Under the conditions of sufficient tooth root bending strength and tooth surface contact strength, the tooth width should be determined with a larger degree of coincidence, and the tooth width should not be blindly increased, so as not to increase the size of the structure.The general tooth width factor is 8-14.The small tooth width should be determined by the allowable tooth root stress, and the width required for the displacement of the force point along the tooth width caused by the inclination angle between the shafts should also be considered.

　　An important way to increase the service life of 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 the value range, its value is Increasing has a greater impact on the increase in coincidence, and when it is greater than this value, the increase in the device value has a smaller impact on the increase in coincidence. For drum-shaped gear couplings with an arc drum curve, the tooth width still determines the drum. The radius of the degree circle is also the parameter of the backlash. The larger the tooth width, the larger the radius of the drum circle, and the larger the backlash required. Therefore, the following two requirements are required: the drum tooth surface of the drum gear coupling The contact conditions of the inner and outer teeth are improved, and the disadvantages of edge extrusion and stress concentration of the straight teeth under the condition of angular displacement are avoided. At the same time, the friction and wear of the tooth surface are improved, the noise is reduced, and the maintenance cycle is long.

　　The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears very convenient.High-speed 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 a high-precision oil filter. , The filtration degree is less than 10 microns, some important high-speed drum gear couplings can also adopt the structure of oil collecting groove hole, that is, the oil collecting groove is machined in the shaft hole of the external gear, and the oil collecting groove is drilled at the bottom of the tooth groove of the external gear. The communicating oil holes use the centrifugal force generated by the high-speed operation of the drum-shaped gear coupling to spray oil into the meshing parts of the inner and outer gears to make them fully lubricated.
