Coupling is a component that connects two shafts axially and transmits torque and motion, and has the ability to compensate for the offset of the two shafts.On this basis, the coupling must be concentric.From a mechanical point of view, the coupling is subject to force. The motor drives the coupling to rotate after being powered on, and then the coupling drives the device to rotate.However, if the coupling is concentric, the power consumption of the motor is normal, and the transmission efficiency will be very high; if the power loss increases when the coupling is not concentric, the transmission efficiency will be reduced, and the current of the motor will naturally increase. The consequences of the motor may be burned.
The so-called drum tooth means that the outer tooth is made into a spherical surface, the center of the spherical surface is on the gear axis, and the tooth side clearance is larger than that of a general gear.The drum-shaped gear coupling can allow a larger angular displacement relative to the straight-tooth coupling.And the contact conditions of the teeth are improved, so that the ability to transmit torque is improved, and the service life of the coupling is prolonged.
If the drum gear coupling is guaranteed to work reliably, good lubrication is indispensable, and replacement can slow 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 accumulate. 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 shaft hole of 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 To get lubricated, we use the centrifugal force generated by the high-speed operation of the drum-shaped gear coupling to spray the oil into the meshing part of the inner and outer teeth.
In order to eliminate the edge extrusion and stress concentration of the straight tooth tooth end of the coupling under the condition of angular displacement, the drum tooth surface improves the contact conditions of the inner and outer teeth, thereby reducing the friction and wear of the tooth surface, and reducing noise.Under the same conditions, the outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the carrying capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling;
