What is the difference between Drum gear cardan universal shaft coupling and drum gear coupling
When the Drum gear cardan universal shaft coupling works, the two shafts produce relative angular displacement, and the inner and outer tooth surfaces periodically slide relative to each other in the axial direction, which will inevitably lead to tooth surface wear and power consumption. Therefore, the Drum gear cardan universal shaft coupling needs to work in a good sealing state.
Drum gear cardan universal shaft coupling has small radial size and large bearing capacity, and is often used for shafting transmission under low speed and heavy load conditions. The toothed coupling has high precision and good dynamic balance, and can be used for high-speed transmission, such as the shaft transmission of gas turbines. Since the angle compensation of the Drum gear cardan universal shaft coupling is greater than that of the spur gear coupling, the drum gear coupling is widely used, and the spur gear coupling is an outdated product, so the person who chooses it should not choose it as much as possible .
Drum gear cardan universal shaft coupling and drum gear coupling belong to rigid-flexible coupling. The gear coupling is composed of inner gear ring and outer gear flange half coupling with the same number of teeth. External teeth are divided into straight teeth and drum teeth. The so-called drum tooth means that the outer tooth is made of spherical surface, its center is on the axis of the gear, and the backlash is larger than that of ordinary gears.
Drum gear cardan universal shaft coupling can allow larger angular displacement (compared with straight coupling), which can improve the contact conditions of teeth, improve torque transmission capacity and prolong service life. Contact state in the tooth width direction during angular displacement. It has radial, axial and angular axis deviation compensation ability, compact structure, small turning radius, large bearing capacity, high transmission efficiency, low noise, and long maintenance period. It is especially suitable for low-speed and heavy-load conditions such as metallurgy, mining, lifting, transportation, etc., and is also suitable for shafting transmission of various machinery such as petroleum, chemical, and general machinery.
