کوپلینگ انعطاف پذیر 5X5 میلی متری ویژه پرینترهای سه بعدی

Description:
A '''coupling '''is used to connect the drive shaft of a power source, such as a 3D Printer to a shaft on a piece of driven machinery.
Flexible couplings compensate for temperature changes and permit end movement of the shafts without placing unwanted stresses on motors and seals. Flexible couplings should not be used to compensate for misalignment at the time of installation. Types of flexible couplings include gear, spring grid, chain, metal disk, and elastomeric.
Flexible coupling can accommodate a slight misalignment between two shafts in 3D printer, but a rigid coupling cannot accommodate any misalignment. Flexible coupling can absorb shocks and backlash but a rigid coupling cannot. A rigid coupling is simple and inexpensive but flexible couplings are expensive.
All flexible couplings consist of two hubs that are attached, with a fit elastomer in between, one each to the driver and driven shafts. The hubs may be attached to the shaft by a keyway, taper fit, screw or other means. The hubs are connected in various ways.
For all flexible couplings, the hubs must be aligned to within the manufacturer’s specifications for the driven equipment, driver, and coupling. In addition, some equipment may require that the coupling permit end float of the shaft, but limit the end float to a certain amount.
The aluminum couplers are usually 5mm motor shaft to 8mm threaded rod. If you are running a 5/16" threaded rod there will be a center-line offset between the motor shaft and the threaded rods. If you use Flexible coupling, the motor can tilt a little on the coupling and absorb any wobble and backlash in the assembly. This eliminated all unwanted wobble issues.
