Characteristics of all kinds of coupling device

1. Elastic coupling

(1) integrated metal elastomer

(2) Zero rotary clearance, synchronous operation

(3) Elastic action compensates radial, angular and axial deviations

(4) High torque rigidity and sensitivity

(5) Clockwise and counterclockwise rotation characteristics are the same

(6) Maintenance free, oil resistance and corrosion resistance

(7) Aluminum alloy and stainless steel materials for choice

(8) There are two main fixing methods: wire jacking and clamping.

2. Diaphragm coupling

(1) High rigidity, high torque, low inertia

(2) using ring or square elastic stainless steel sheet deformation

(3) Large torque bearing, high torque rigidity and sensitivity

(4) Zero rotation clearance, clockwise and counterclockwise rotation characteristics are the same

(5) Maintenance free, oil resistance and corrosion resistance

(6) Double stainless steel diaphragm can compensate radial, angular, axial deviation, single diaphragm can not compensate radial deviation.

3. Bellows coupling

(1) No backlash, torsional rigidity, reliable connection, corrosion resistance, high temperature resistance

(2) Maintenance-free, oil-resistant, bellows shape structure compensates radial, angular and axial deviation, can also keep constant speed operation in case of deviation

(3) Clockwise and reverse needle rotation characteristics are the same

(4) Bellows are made of phosphor bronze and stainless steel

(5) Can be used for high precision and stability requirements of the system.

4. Slider coupling

(1) no backlash connection, simple transmission structure for small torque measurement

(2) Easy to use, easy to install, save time, wide size range, small moment of inertia, easy to visual inspection

(3) Oil corrosion resistance, electrical insulation, available for different materials slider elastomer selection

(4) The sliding between the bushing and the middleware can allow large radial and angular deviation, the special convex design of the middleware has the function of supporting, allowing large Angle deviation, does not produce bending moment, and the load of the axle is reduced.

5. Quintuple coupling

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

(2) Can absorb vibration, compensate radial and angular deviation

(3) Simple structure, convenient maintenance, easy to check

(4) Maintenance-free, oil resistance and electrical insulation, working temperature of 20℃-60℃

(5) The plum blossom elastomer has four, six, eight and ten valves

(6) Fixed with top wire, clamping, keyway fixed.

6. Rigid coupling

(1) Light weight, ultra-low inertia and high sensitivity

(2) Maintenance-free, oil and corrosion resistance

(3) eccentricity is not allowed, and the shaft should be exposed as far as possible when used

(4) The main material is aluminum alloy/stainless steel

(5) Fixing methods include clamping and wire fixing.
