Henan ml series plum blossom elastic coupling shock absorption and wear resistance

  Henan ml series plum blossom elastic coupling shock absorption and wear resistance:
  There are two types of plum blossom couplings, one is the traditional straight claw type, and the other is the curved (concave) claw type zero clearance coupling
The traditional straight claw type plum blossom coupling is not suitable for high precision servo drive applications
The zero clearance claw type plum blossom coupling is evolved from the straight claw type, but the difference is that its design is suitable for the application of servo system
It is often used to connect servo motor, stepping motor and ball screw
The curved surface is to reduce the deformation of the elastic plum blossom spacer and limit the influence of the centripetal force on it during high-speed operation
The zero clearance claw coupling is composed of two metal shaft sleeves (usually made of aluminum alloy, or stainless steel) and a plum blossom elastic spacer The plum blossom elastic coupling is applicable to the transmission shaft system connecting two coaxial lines, with compensation for the relative offset of the two shafts, shock absorption, wear resistance and cushioning performance; The working temperature is -35 ℃ ~+80 ℃, and the transmission nominal torque is 16-25000n m
The allowable speed is 10900-1900r/min, the diameter range of shaft hole is 14-140mm, the length of shaft hole is 42-252mm, and the length of shaft hole is 42-252mm The plum blossom coupling has simple structure, no lubrication, convenient maintenance, easy inspection and maintenance free, and can operate continuously for a long time
High strength polyurethane elastic element is wear-resistant and oil resistant, with large bearing capacity, long service life, safety and reliability
Stable and reliable operation, with good vibration damping, cushioning and electrical insulation performance
It has large axial, radial and angular compensation capabilities
Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions Quincunx couplings have good balance performance and are suitable for high-speed applications (up to 30000 RPM), but can not handle large deviations, especially axial deviations
Larger eccentricity and deflection angle will produce greater bearing load than other servo couplings
Another concern is the failure of the plum blossom coupling
Once the plum blossom elastic spacer is damaged or fails, the torque transmission will not be interrupted
At the same time, the metal claws of the two shaft sleeves mesh together to continue to transmit torque, which is likely to cause problems in the system
Selecting appropriate plum blossom elastic spacer material according to actual application is a major advantage of this coupling
Some automation equipment companies can provide plum blossom spacer of various elastic materials with different hardness and temperature bearing capacity, so that customers can select appropriate materials to meet the performance standards of practical application

The plum blossom coupling is machined by turning, milling, broaching and other machining methods, and then subjected to overall heat treatment
In order to ensure sufficient mechanical strength, there is also a kind of claw plate on the market, which is a casting, which can be produced in large quantities without processing loss
Therefore, the price is much lower than that of machining But the casting performance is not very good
Don't use it on some important occasions
In addition, the claw teeth of the casting are prone to tooth cracking (claw teeth fall off) at high speed or under high load
(1) Compact, no backlash, three kinds of elastomers with different hardness; (2) It can absorb vibration and compensate radial and angular deviation; (3) Simple structure, convenient maintenance and inspection; (4) Maintenance free, oil resistant and electrical insulation, operating temperature 20 ℃ -60 ℃; (5) Plum blossom elastomer has four, six, eight and ten petals; (6) The fixing methods include jackscrew, clamping and keyway fixing
