Tension spring gear coupling

Tension spring gear coupling

Tension spring tooth profileCouplingIt is suitable for the connection of two shafts in high-speed devices and mechanical equipment.The tension spring toothed coupling includes a hub-shaped half coupling with a connecting plate and a hub-shaped half coupling with an outer ring gear. A sector-shaped tooth centrifugal block is arranged on the assemblage, which can be wound around its own shaft. The center rotates, the outer surface of the centrifugal block is made into a ring groove, and an elastic ring is installed in the ring groove.

     Tension spring tooth profileCouplingIt is suitable for the connection of two shafts in high-speed devices and mechanical equipment.The tension spring toothed coupling includes a hub-shaped half coupling with a connecting plate and a hub-shaped half coupling with an outer ring gear. A sector-shaped tooth centrifugal block is arranged on the assemblage, which can be wound around its own shaft. The center rotates, the outer surface of the centrifugal block is made into a ring groove, and an elastic ring is installed in the ring groove.In addition, a tension spring is installed on the connecting plate half coupling, one end of which is fixed on the centrifugal block in pairs, and the other end is fixed on the connecting plate along the circumference, and the fixed point is symmetrical with the axis of the two centrifugal blocks.In a static state or when rotating in any direction without load, the outer gear ring of one coupling half is in mesh with the sector teeth of the centrifugal block of the other half coupling. Under the action of torque, the half coupling with outer gear ring The device rotates with the sector teeth of the centrifugal block, and the tension spring is stretched and drives the hub of the disc half coupling to rotate.At this time, the symmetrical axis of the centrifugal block deviates from the symmetrical axis of the half-coupling by an angle, that is, one half-coupling drives a corresponding angle relative to the other half-coupling.When the rotation speed increases, under the action of centrifugal force, the centrifugal block returns to the initial position and maintains dynamic balance.When the centrifugal block rotates, the elastic ring can play the role of friction and vibration reduction, thus can eliminate torsional vibration.The use of this coupling can improve the damping effect on torsional vibration and dynamic load, and improve the sensitivity of rotation stability.
