STRESS CONCENTRATION PHENOMENON IN GRID COUPLINGS

When the concentricity of the driving shaft and the driven shaft changes, the serpentine spring coupling will experience stress concentration;When working at high speed, you can consider using lubricating oil, but you must have a reliable seal, and apply sealant if necessary.When the grid coupling uses lubricating oil, under the action of centrifugal force, the metal wear debris adheres to the inner surface of the housing, so that the oil on the spring can be kept clean.

Grid spring couplings can reliably transmit torque and motion and must work in a well-sealed state.The elastic snake spring of the snake spring coupling has a certain compensation effect on the center deviation, but the relative free movement of the two hubs must be ensured during installation and operation.Serpentine spring shaft coupling are widely used in heavy machinery and lifting equipment.

There is a lubrication groove on the inside of the Hub for easy lubrication.The springs are arranged in an orderly manner within the teeth of the hub and must not be loose.There is a space between the spring and the cover to store grease and compensate for the loss of grease to reduce stress concentration, prevent spring breakage in the serpentine steel flex coupling, and increase the life of the serpentine spring coupling.
