Rigid couplings connect rotating members such as shafts and transmit torque and motion. They permit neither axial nor radial relative motion between the shafts of the driver and driven unit. When the two shafts are connected solidly and properly, they operate as a single shaft. A rigid coupling is primarily used for vertical applications like vertical pump. Most rigid couplings are made of aluminum, steel, or stainless steel. Shrink discs are rigid couplings with two external rings that tighten together axially and exert inward force on a third ring via tapered surfaces. This closes the inner ring onto the shafts and provides a secure connection. Rigid couplings with keyways include keys that can be used to stop the rotation of the shaft couplings. The couplings require accurate machining to avoid a potentially catastrophic misalignment.
Rigid Gooseneck Trailers are engineered for strength, durability and safety. It provides solutions for quick and efficient loading of multiple pieces of equipment. This trailer is designed with beavertail and ramps for rear loading. Its carrying capacity ranges from 35 ton to 200 tons.
Rigid in compression locking gas springs have oil on both sides of the piston so that the chamber between (where the rod enters the body) and the piston are always full of oil. The oil is contained in the closed end of the tube and a floating piston retains the gas in the nose bearing end chamber. When a compressive load is applied to the locked rod, the oil between the piston and the closed end of the tube does not compress and the rod cannot move. Applications include operating, massage and veterinary tables and wheel chair recline and support systems amongst many others.
Rigid in tension locking gas springs have oil on both sides of the piston so that the chamber between (where the rod enters the body) and the piston are always full of oil. This oil is contained by a floating piston that separates it from the gas in the enclosed tube. Since oil is incompressible, when a tension load is applied to the locked rod the oil between the nose bearing and the piston does not compress and the rod cannot move. Applications for rigid in tension locking springs include hospital beds, aircrafts, coach and rail seat back recline control and wheel chair recline and support systems.
