Rigid Clamping GNC 28.5X 38 Aluminum Alloy Shaft Coupling For Machine
Products Features
The flanged coupling is a rigid coupling, which is to connect two half-couplings with flanges to the two shafts with ordinary flat keys, and then use bolts to connect the two half-couplings into one to transmit motion. and torque. This kind of coupling has two main structural forms: 1. Relying on the hinged hole to use bolts to achieve the alignment of the two shafts and relying on the bolt rod to withstand extrusion and shearing to transmit torque; 2. relying on a half-coupling on the The shoulder is aligned with the groove on the other coupling half.
>Integrated structure, the overall use of high-strength aluminum alloy materials
>High torque, high rigidity
>The rigid type basically does not allow eccentricity, so it must be fully adjusted in use
>Fastening method of setscrew screw
