Among a wide variety of couplings,
Drum gear couplingIt has a small transmission torque, strong ability to absorb connection errors, and excellent durability. Its function is to connect the driving shaft and the driven shaft, and the transmission torque makes the two shafts rotate together. It is a common connection in medium and heavy machinery. Parts of the two drive shafts.
With the development of modern industrial technology, technical and economic indicators such as the bearing capacity, reliability, efficiency, circumferential speed, volume and weight of the drum gear coupling have been put forward increasingly higher requirements.Drum gear couplings are developed on the basis of straight gear couplings to meet the technical requirements of large inclination angle, variable inclination angle, small size and high reliability.The structure of the drum-shaped gear coupling is symmetrical. The teeth on the outer gear sleeve are drum-shaped teeth from the direction of the tooth tip, and the tooth thickness gradually decreases from the center to the two sides. The teeth are straight teeth.Because the tooth tip and tooth surface of the external gear sleeve are arc-shaped, the entire coupling is double articulated and flexible, so that it can adapt to the large deflection angle between the two axes.The drum gear coupling plays an important role in production practice. It can compensate for the angular error caused by the misalignment of the axes of the two coupling shafts, the axial and radial installation errors, and allow a certain displacement of the two shafts.
