The Importance Of Good Sealing Working Condition For Drum Gear Coupling

The progressive contact meshing transmission of the inner and outer tooth surfaces of the drum-shaped gear coupling avoids the disadvantages of edge extrusion and stress concentration of spur tooth tips under angular displacement conditions, and at the same time reduces tooth surface friction and wear. The noise is reduced and the maintenance cycle is long. It has become common for drum-shaped gear couplings to be used in high-speed transmission shaft systems after undergoing dynamic balancing tests. The drum gear coupling has a small radial size and a large load-bearing capacity. It is often used for shaft system transmission under low-speed and heavy-load conditions. High-precision and dynamically balanced drum gear couplings can be used for high-speed transmission, such as combustion engines. Shaft transmission of steam turbine.

We select the coupling type based on comprehensive factors such as power machine and coupling load type, rotation speed, and working environment, and select the coupling type based on factors such as coupling matching and connection conditions. Based on the nominal torque, shaft hole diameter and shaft hole length, the model of drum gear coupling is determined. Drum gear couplings are widely used in shaft transmission of metallurgical machinery and heavy machinery. In high-speed and heavy-load power transmission, some couplings also play the role of buffering, vibration reduction and improving the dynamic performance of the shaft system. The coupling consists of two hubs, which are connected to the driving shaft and the driven shaft respectively.

When using couplings, the equipment in the shaft system such as diesel engines, gearboxes, shaft systems and highly elastic couplings must complement each other in design and use, and their design and manufacturing levels are also relatively high, so The quality of the designed ships is also very high. The sinking of the main machine's shock absorber causes the shaft system of the coupling to become asymmetrical, thereby increasing the additional torque. This causes the highly elastic coupling to heat up and cause breakage accidents during use. Because the scope of use of couplings is relatively wide, they are widely used in many industries.

Improper use in specific situations or lack of thorough consideration during use may also cause the coupling to be damaged during use. When the drum gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the drum gear coupling requires working under a good sealing condition, the drum gear coupling is composed of an inner ring gear with the same number of teeth and a flange half coupling with external teeth. The teeth of the drum-shaped gear coupling are in contact with each other. conditions, improve the ability to transmit torque and extend the service life.
