GIICL / GIICLZ drum gear coupling production prices manufacturers Taiyuan drum gear coupling with radial, axial and angular axis deviation, such as the ability to compensate, with a compact, small turning radius, large carrying capacity, transmission efficiency High, low noise and long service intervals, etc., especially for low-speed heavy-duty operating conditions, such as metallurgy, mining, lifting and transportation industries, but also for petroleum, chemicals, machinery and other general machinery drive shaft, drum gear coupling are just flexible coupling, gear coupling is composed of the same number of teeth of the ring gear and flange coupling half with external teeth and other parts. Straight teeth and outer teeth into two toothed drum gear, drum gear is called the outer teeth made of spherical, sphere centered on the axis of the gear, the gear backlash than the average large drum gear coupling can allows a larger angular displacement (relative to straight teeth couplings), tooth contact conditions can be improved to enhance the ability to transfer torque and prolong life. Contact state along the tooth width when the angular displacement. Gear coupling at work, generating two axes relative angular displacement, relative sliding axially inner and outer tooth surfaces periodically teeth, will inevitably lead to tooth wear and power consumption, therefore, gear couplings need to have a good and Work under the seal of the state. Small gear coupling radial size, large carrying capacity, commonly used in low-speed heavy working conditions shaft drive, precision and by balancing the gear coupling can be used for high-speed transmission, such as gas turbine shafting drive. As the drum gear coupling angle to compensate more than straight teeth coupling, at home and abroad are widely used drum gear coupling, straight gear coupling products are being phased out, the choice should try not to choose . Drum gear coupling characteristics (compared with straight teeth coupling has the following characteristics): 1, drum gear coupling loading capacity. Under the same set of outer and inner tooth couplings maximum diameter, drum gear coupling carrying capacity than the straight average of gear coupling 15 to 20% 2, the angular displacement of the large amount of compensation. When the radial displacement is zero, straight teeth coupling permissible angular displacement of 1o, and drum gear coupling permissible angular displacement of 1o30'''', increased by 50%. In the same modulus, teeth, tooth width, the drum-shaped spur gear ratio allows a large angular displacement, 3, the drum-shaped drum gear coupling tooth surface to make contact to improve the conditions of outer teeth, avoiding the the angular displacement of the teeth of the end conditions BARS edge extrusion, the drawbacks of the stress concentration, and improves the tooth surface friction, wear condition, reducing the noise and long maintenance cycle. Four, drum-shaped outer tooth gear coupling sleeve trumpet shaped tooth end, so that the inner and outer tooth disassembly is very convenient. 5, the drum gear coupling transmission efficiency up to 99.7%. Based on the characteristics of the Scripture, at present, at home and abroad has generally been an alternative to straight teeth drum gear coupling. 6, I plant couplings short duration, fast delivery.
