Henan CIICL type drum gear coupling

The CIICL type drum gear coupling is suitable for connecting two horizontal coaxial transmission shafts through an intermediate shaft, and has the ability to compensate for the relative deviation of the two shafts.

Type I-The sealed end is a separate type, with a large tooth spacing, which can allow a large radial displacement, and can be connected with Y, J1, and Z1 shaft extensions.

Type Ⅱ-The sealing end is integral, with small tooth spacing, relatively small radial displacement, compact structure, small moment of inertia, and can be connected with Y and J1 shaft extensions.

GIICL drum gear coupling has the ability to compensate for axis deviations such as radial, axial and angular axis. It has the advantages of compact structure, small gyration radius, large carrying capacity, low transmission, low noise and long maintenance cycle. It is especially suitable for low speeds. Heavy-duty conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmissions of various machinery such as petroleum, chemical, general machinery, etc.Drum gear couplingIt belongs to a rigid-flexible coupling. The gear coupling is composed of an internal gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum-shaped gear couplings allow Larger angular displacement (compared to spur gear coupling), the contact condition of the teeth can be improved, the ability of transmitting torque is improved, and the service life is prolonged.The contact state along the tooth width when there is angular displacement.When the gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling must have a good and Work in a sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft transmissions.Since the angular compensation of drum gear couplings is greater than that of spur gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products and should not be used as much as possible.

Maintenance method of GIICL drum gear coupling

How to analyze the maintenance method of GIICL drum gear coupling? Good lubrication is the operation of drum gear coupling, and it also reduces wear.Under the condition of sufficient tooth root bending strength and tooth surface contact strength, the tooth width should be determined with a larger degree of coincidence, and the tooth width should not be blindly increased to avoid increasing the structural size.The general tooth width factor is 8-14.The width of the small tooth should be determined by the allowable root stress, and the width required for the displacement of the force point along the tooth width caused by the inclination angle between the shafts should also be considered.

An important way to improve the service life of GIICL 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 coincidence degree. When the tooth width coefficient is less than the value range, its value is Increasing has a greater impact on the increase in coincidence, and when it is greater than this value, the increase in the device value has a smaller impact on the increase in coincidence. For drum-shaped gear couplings with an arc drum curve, the tooth width still determines the drum. The radius of the degree circle is also a parameter of the backlash. The larger the tooth width, the larger the radius of the bulge circle, and the greater the backlash required.
