▎ 摘　　要

NOVELTY - The net-shaped flexible coupling comprises a ball net (1) whose upper and lower sides are provided with flange (2). The outer side of the ball net is provided with a spiral mesh (4). The spiral mesh has a rust-proof layer, a toughness layer, a bending-resistant layer and a wearable layer. The bottom of the anti-rust layer is fixedly connected with the top of the toughness layer, and the bottom of toughness layer is connected with a top portion of the bending resistant layer. The bottom portion of bending resistant layers, the bottom portion is connected to the top of the wearable layer. A connecting plate (3) is fixed at both ends of the spiral mesh. A disassembly mechanism (5) is provided inside the connecting plate. The rust-proof layer is graphene coating. USE - Net-shaped flexible shaft coupling for three-dimensional (3D) printing used in mechanical transmission structure. Can also be used for connecting two shafts of different mechanisms to transmit torque. ADVANTAGE - The connecting plate and the spiral knitting net can be detached to replace, which increases the convenience. The self-adapting adjusting property is strong, screwing the rotating head. The rust-proof layer and the toughness layer are fixedly connected by adhesive. The anti-breaking effect is better, by the anti-rust layer. The service life of the spiral woven net is prolonged. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a net-shaped flexible shaft coupling for three-dimensional printing.
