Among a wide variety of couplings,
Drum gear couplingIt has the advantages of small size, large transmission torque, strong ability to absorb coupling errors, and excellent durability. It is the most common component that connects two drive shafts in medium and heavy machinery. In engineering practice, due to manufacturing and installation errors, parts Deformation, wear, and foundation sinking will cause the axis positions of the two shafts to shift, resulting in axial displacement, radial displacement, angular displacement, and comprehensive displacement.The existence of offset causes additional dynamic loads on shafts, bearings, and couplings, causing vibrations and worsening the working conditions of machine parts.
With the development of near-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 high requirements.Drum gear couplings are developed on the basis of straight gear couplings to meet the technical requirements for inclination, variable inclination, small size and high reliability.The structure of the drum-shaped gear coupling is basically symmetrical. The teeth on the outer gear sleeve are drum-shaped teeth viewed from the direction of the tooth tip. The tooth thickness gradually decreases from the center to the two sides, and the inner gear ring meshes with it. The upper 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.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.
