Good lubrication is
Drum gear couplingA necessary guarantee for safe and reliable operation is also a necessary condition for slowing down wear.
Most of the high-speed drum gear couplings are lubricated by lubricating oil. The lubricating oil needs to be filtered by a high-precision oil filter with a filtration degree of less than 10 microns. The tooth surface requires continuous lubrication, otherwise the temperature of the tooth surface will increase and moisture and water will be accumulated. Dirt, some high-speed drum gear couplings sometimes use the structure of the oil collecting groove, that is, the oil collecting groove is machined in the external gear, and the oil hole communicating with the oil collecting groove is drilled at the bottom of the external gear tooth groove, in order to make it fully lubricated , We use the centrifugal force generated by the high-speed operation of the drum-shaped gear coupling to spray oil into the meshing part of the inner and outer teeth.
An important way to improve 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 degree of coincidence. When the tooth width coefficient is less than a certain value range, the increase of its value has a greater impact on the increase of the coincidence degree. When it is greater than this certain value, the increase of the device value has a smaller impact on the increase of the coincidence degree. For drum-shaped gear couplings of the degree line, the tooth width is still a parameter that determines the drum radius and backlash. The larger the tooth width, the larger the drum radius and the greater the backlash required.
