Are spider coupling flexible?
These spider / jaw mechanical power transmission couplings are torsionally flexible shaft couplings, the operating characteristics of which are two hubs with concave claws, transmitting the torque by meshing with an elastic involute gear ring.
How many types of coupling spiders are there?
Six different types of couplings described.
What is a flexible jaw coupling?
Flexible Jaw couplings are generally used to connect continuous-duty electric motors with driven machinery, pumps, and gearboxes. In jaw couplings, the element is loaded in compression between the jaws of mating hubs. These jaws operate in the same plane, with the driving hub jaws pushing toward the driven hub jaws.
What circumstances flexible couplings are used?
Flexible couplings are usually used to transmit torque from one shaft to another when the two shafts are slightly misaligned. They can accommodate varying degrees of misalignment up to 1.5° and some parallel misalignment. They can also be used for vibration damping or noise reduction.
What is the purpose of flexible coupling?
The function of a flexible coupling is to transmit torque from the driver to the driven machine while making allowances for minor shaft misalignment and shaft end position changes between the two machines.
What are the operating characteristics of a spider coupling?
Spider couplings are torsional flexible shaft couplings, the operating characteristics of which are two hubs with concave claws, transmitting the torque by meshing with an elastomer involute gear ring.
What kind of steel is used in Spider jaw couplings?
Large stocks for quick delivery and in-house machine shop for exact fit to your application machinery. • Hub material: Aluminium (Al), Cast Iron (GG/GGG), Sintered Steel (Si), Steel (St). The important information you need for these spider / jaw type mechanical power transmission couplings.
Why are spiders used in McMaster Carr couplings?
Spiders act as a cushion between the two hubs, reducing vibration and compensating for slight shaft misalignment. No need to remove hubs, disconnect shafts, or move equipment to replace worn split spiders— they are split along one side for easy installation and removal.
What can Spidex power transmission couplings be used for?
Spidex power transmission couplings can be used for horizontal as well as for vertical shaft connections, for reversing, intermittent service and are electrically insulating. The operating characteristics and the durability of the coupling are very positively influenced by the high overall precision of the machining, especially the claws,…
