China Factory DJM 04 Flexible Disc Coupling for Chemical Industrial Lowes Air Compressor
Product Description
A coupling is a device used to connect 2 shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.
The primary purpose of couplings is to join 2 pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.
Benefits of DJM 04 Shaft Couplings
- Allows for the connection of shafts of units that are manufactured separately, enabling easy disconnection for repairs or alterations.
- Provides flexibility and accommodates misalignment of the shafts.
- Reduces transmission of shock loads from one shaft to another.
- Offers protection against overloads.
- Alters the vibration characteristics of rotating units.
- Connects the driving and driven parts.
- Efficiently transfers power from one end to another (e.g. motor to pump).
Disc couplings, like the DJM 04 Flexible Disc Coupling, transmit torque from a driving to a driven bolt tangentially on a common bolt circle. Torque is transmitted between the bolts through a series of thin, stainless steel discs assembled in a pack. Misalignment is accomplished by deforming the material between the bolts.
