The characteristics and application scope of plum coupling

The plum blossom coupling is a kind of coupling, and it is widely used at present. The staff of Ever-Power mechanical processing plant will give a brief introduction below:

XNUMX. Feature of plum coupling:

The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.With sufficient mechanical strength, there is also a kind of claw plate on the market that is a casting, which can be produced in large quantities and avoids processing losses.

At the same time, because the elastic body of the plum blossom coupling is generally composed of engineering plastics or rubber, the life of the coupling is also the life of the elasticity. The life of the general elastomer is 10 years, so the service life of the plum blossom coupling is still very long. long.

XNUMX. Application range of plum coupling:

Plum couplings are used in CNC machine tools, CNC lathes, processing, engraving machines, CNC milling machines, computer gongs, metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, lifting machinery, transportation machinery, light industry machinery, textile machinery, water pumps, Fans and other industries have a wide range of applications.

There are two main types of plum blossom couplings, one is the traditional straight claw type, and the other is the curved (concave) claw type zero-backlash coupling.The traditional straight-jaw plum blossom coupling is not suitable for use in high-precision servo transmission applications.The zero-backlash claw type plum blossom coupling is evolved on the basis of the straight claw type, but the difference is that its design can be suitable for the application of the servo system, and is often used to connect servo motors, stepping motors and ball screws.The curved surface is to reduce the deformation of the elastic plum spacer and limit the influence of centripetal force on it during high-speed operation.The zero-clearance claw coupling is composed of two metal sleeves (usually made of aluminum alloy, stainless steel can also be provided) and a plum blossom elastic spacer.The plum blossom elastic spacer has multiple leaf branches. Like a slider coupling, it also squeezes the plum blossom elastic spacer and the sleeves on both sides to match, and thus its zero clearance performance.Different from the slider coupling, the plum blossom coupling is driven by squeezing while the slider coupling is driven by shear.When using a zero-clearance claw coupling, the user should pay attention not to exceed the large bearing capacity of the elastic element given by the manufacturer (under the premise of zero clearance), otherwise the plum elastic spacer will be squashed and deformed and lose its elasticity. The disappearance of the preload, resulting in the loss of zero-gap performance, may also be discovered by the user after a serious problem occurs.

The plum blossom coupling is simple in structure, does not require lubrication, is convenient for maintenance, easy for inspection, maintenance-free, and can run continuously for a long time.Polyurethane elastic elements are resistant to oil, have large carrying capacity, and have a long service life.Work stably, with good vibration damping, buffering and electrical insulation properties.It has large axial, radial and angular compensation capabilities.The structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed occasions.
