XL plum blossom star coupling

Plum blossomCouplingIt is a widely used coupling, also called a claw coupling, which is composed of two metal claw discs and an elastic body.The two metal claws are generally made of No. 45 steel, but aluminum alloys are also useful when load sensitivity is required.

  Plum blossomCouplingIt is a widely used coupling, also called a claw coupling, which is composed of two metal claw discs and an elastic body.The two metal claws are generally made of No. 45 steel, but aluminum alloys are also useful when load sensitivity is required.

  Plum blossomCouplingCraftsmanship:

  Plum couplingIt is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.In order to ensure sufficient mechanical strength, there is also a claw plate on the market that is a casting, which can produce large quantities of two types of plum couplings, and eliminates processing losses.So the price is much lower than machining. But the performance of castings is not very good.It is better not to use it in some important occasions.In addition, the claws of the casting are prone to tapping (the claws fall off) at high speed or high load.

  (1)Compact, no backlash, providing three different hardness elastomers;

  (2) It can absorb vibration and compensate radial and angular deviation;

  (3) Simple structure, convenient maintenance and easy inspection;

  (4) Maintenance-free, oil-resistant and electrical margin, working temperature 20℃-60℃;

  (5) Plum blossom elastomer has four petals, six petals, eight petals and ten petals;

  (6) The fixing methods include top wire, clamping and keyway fixing.
