Drum gear couplings have the advantages of small size, large transmission torque, strong ability to absorb coupling errors, and good durability among a wide range of couplings. It is common in medium and heavy machinery to connect two drive shafts. part.
With the rapid development of modern industrial technology, technical and economic indicators such as the carrying capacity, reliability, efficiency, circumferential speed, volume and weight of the drum gear coupling have been put forward increasingly high requirements.The drum gear coupling is developed on the basis of the straight gear coupling to meet the technical requirements of large inclination, variable inclination, small size and high reliability.The structure of the drum gear coupling is basically symmetrical.From the direction of the tooth tip, the teeth on the outer gear sleeve are drum-shaped teeth, and the tooth thickness gradually decreases from the center to both sides. The teeth on the inner gear ring that mesh with it are straight teeth.
Since the top of the outer gear sleeve and the tooth surface are arc-shaped, the entire coupling is double articulated and flexible, so that it can adapt to the larger deflection angle between the two axes.Drum gear couplings play an important role in production practice.It can compensate the angular error caused by the misalignment of the two connecting shafts, the axial and radial installation errors, and allow a certain displacement of the two shafts.
