KGC3-45 is a gear coupling inner hub with a module of 2.5, 42 teeth, and a 45 mm bore diameter. It is made of S45C steel with induction-hardened gear teeth rated at 50~60 HRC. The hub has a pitch diameter of 105 mm, an outside diameter of 110 mm, a face width of 20 mm, and a total length of 135 mm. A keyway of 12 mm width by 3.3 mm depth complies with JIS B1301 standards. The allowable torque is 785 N·m (80 kgf·m), and the backlash ranges from 0.40 to 0.60 mm. The part weighs 2.74 kg. Set screws and snap ring grooves are not included. Secondary operations are prohibited on tooth areas due to induction hardening.

Couplings Types
Couplings can be divided into two categories: flexible and rigid. Both types are used to connect two rotating shafts driven by a motor and transmit torque and angular velocity; however, flexible couplings and shafts are designed to accommodate angular misalignment, angular offset, axial movement, and a variety of load conditions. A flexible coupling is pliable due to the twisting and compression of a durable, adaptable material, like neoprene, rubber, or silicone.
Flexibility can also be achieved with thin metal disks, corrugated aluminum bellows (bellows couplings), or even a stainless-steel ball (miniature ball couplings). Some materials can provide vibration reduction, as in our precision flexible antivibration couplings.
Rigid couplings are limited by comparison; rigid couplings are used when shafts are already positioned in precise lateral and angular alignment. Their rigid design inhibits shaft misalignment. They can generally transmit more power than flexible couplings due to their rigidity.
Even the most complicated application challenges can be solved by our skilled engineers, they will identify the best coupling solution for your application. SDP/SI provides a comprehensive range of rigid and flexible couplings. Many of our precision couplings, including the Miniature Bellows Coupling and the Neo-Flex Coupling, have our patented Fairloc® Hub design, which solves phasing, timing, positioning, and frequent removal problems.
