Sealing condition of Curved-tooth Gear Coupling

Curved-tooth Gear Coupling

After the machine has been used for a long time, its various parts will also age, and even some of them will be damaged during operation. If these hazards cannot be found in time, it will not only cause low efficiency during operation and use, but also may cause damage to the staff. The same is true for Curved-tooth Gear Couplings. Before each use, check the condition of each component to see if there is any damage or failure. If there is any, repair it in time and loosen the lubricating oil of the machine. If there is not enough oil, add more.

When refuelling, you should not add too much, as long as it reaches the standard value. Adding too much will only burden the machine, and cause the machine to malfunction. The Curved-tooth Gear Coupling has the ability to compensate radial, axial and angular axis deviation, which is especially suitable for low-speed and heavy-load working conditions, such as metallurgy, mining, lifting and transportation, and also for shafting transmission of various machinery such as petroleum, chemical, general machinery, etc. The Curved-tooth Gear Coupling is a rigid and flexible coupling, which is composed of internal gear ring with the same number of teeth and flange half coupling with external teeth, and is convenient to use.

The external teeth are divided into straight teeth and drum teeth. The so-called drum tooth is to make the external teeth into a spherical surface, the spherical center is on the gear axis, and the tooth side clearance is larger than that of ordinary gears. The Curved-tooth Gear Coupling can allow larger angular displacement, improve the contact conditions of the teeth, improve the ability to transmit torque, extend the service life, and the contact state along the tooth width when there is angular displacement. When the Curved-tooth Gear Coupling works, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth periodically make axial relative sliding, resulting in tooth surface wear and power consumption. Therefore, the Curved-tooth Gear Coupling needs to work under a good sealing condition.

The Curved-tooth Gear Coupling has small radial size and large bearing capacity, and is often used for shafting transmission under low speed and heavy load conditions. The Curved-tooth Gear Coupling with dynamic balance can be used for high-speed transmission, such as shafting transmission of gas turbine. The gear blank only performs rotary motion, and the hob center performs circular motion to complete the vertical feed and horizontal feed of the gear blank. This method is adopted when the gear hobbing machine is equipped with a hob feed mechanism for processing drum teeth; The Curved-tooth Gear Coupling is not suitable for machinery requiring vibration reduction, buffering and alignment. The surface needs to be carburized or tempered, otherwise the hardness of the tooth surface is different.
