Rubber gear coupling is a type of toothed coupling that utilizes the meshing of internal and external teeth to achieve the transmission of torque and rotational motion between the two halves of the coupling. This type of coupling is suitable for connecting transmission shaft systems with two concentric shafts and has a certain compensation performance for the relative displacement of the two shafts. It consists of main components such as an internal gear ring, a gear shaft sleeve, and an end cap. Generally, small-sized gear coupling end caps and internal gear rings can form a whole. Rubber gear couplings are widely used in various mechanical industries such as metallurgy, mining, lifting and transportation, petroleum, and shipbuilding due to their compact structure, high load-bearing capacity, wide range of operating speeds, and reliable performance.
The design and manufacturing of rubber gear couplings consider various material options, including different rubber materials such as NBR, EPDM, Viton, FKM, FFKM, NR, HNBR, CR, SBR, PU, TPU, etc. These materials provide different hardness (30 °~95 °), color (the most common being black, white products may be slightly more expensive), and adaptability to working environments. In addition, factors such as procurement quantity, size, material, hardness, color, tolerance, and working environment need to be considered when customizing rubber gear couplings. In order to provide faster and more accurate services, it is recommended that customers provide detailed inquiry information, including the parameters mentioned above, so that manufacturers can produce rubber gear couplings that meet customer needs
