Coupingused to join different organizations in the two axis (driving shaft and driven shaft) to rotate to common transmission torque of mechanical parts.The overloaded power transmission at high speed, some coupling and buffer, vibration and enhance the role of shaft system dynamic performance.Coupling consists of two parts, respectively, and the driving shaft and driven shaft connection.Most general engine by means of coupling machine connected with work.
Commonly used precision couplings are: the elastic coupling, diaphragm coupling, bellows couplings, oldham coupling, plum coupling, rigid coupling.
The characteristics of
1. The elastic coupling(1) a integrated metal elastomer(2) zero rotation clearance and synchronous operation(3) the elastic compensation radial, angular and axial deviation(4) high torque and excellent rigidity sensitivity(5) is exactly the same clockwise and counterclockwise rotation characteristics(6) is a maintenance free, oil resistance and corrosion resistance(7) of aluminum alloy and stainless steel materials to choose from(8) fixed way mainly covered yarn and clamping two kinds.
2. The diaphragm coupling(1) high rigidity, high torque and low inertia(2) adopting the circular or square stainless just slice deformation(3) carrying large torque, high torque and excellent rigidity sensitivity(4) zero rotation clearance, clockwise and anticlockwise rotation characteristics are the same(5) is a maintenance free, strong resistance to oil and corrosion resistance(6) double stainless steel diaphragm can compensate radial, angular and axial deviation, single diaphragm cannot compensate radial deviation.
3. The bellows coupling(1) no backlash, twist to the rigid, reliable connection, corrosion resistance, high temperature resistant(2) free maintenance, strong resistance to oil, corrugated tube structure compensation Angle to the radial, and axial deviation, deviation of the presence of also can keep the constant actuation(3) clockwise and reverse the needle turning feature exactly the same(4) the material is phosphor bronze and stainless steel bellows to choose from(5) can be suitable for used in the system of high accuracy and stability requirements.
4. The oldham coupling(1) no backlash connection, for small torque measuring transmission structure is simple(2) easy to use, easy to install, save time, wide range of size, moment of inertia of small, easy to visual inspection(3) oil resistance, electrical insulation, for different materials of slider elastomer to choose(4) the shaft sleeve and sliding between the middleware can allow big Angle to the radial and bias, middleware support the role of the special protruding point design, allows a larger angular deviation, do not produce the bending moment, kan axial load to a minimum.
5. Plum coupling(1) compact, no backlash, provides three different hardness of the elastomer(2) can absorb vibration, radial and angular deviation compensation(3) simple structure, convenient maintenance, easy to check(4) is a maintenance free, oil resistance and electrical insulation, the working temperature of 20 °C to 60 °C(5) the plum blossom has four petals, six petals, eight disc elastomer and ten disc(6) fixed way covered wire, clamping, keyway fixed.Rigid coupling
6.(1) light weight, low inertia and high sensitivity(2) free maintenance, strong oil resistance and corrosion resistance(3) not allow eccentric, when using, should as far as possible let shaft leakage(4) optional subject material aluminum alloy/stainless steel(5) the way of fixed clamping, with the top wire fixation.Coupling main use (for reference)Elastic coupling: suitable for rotary encoders, stepper motorDiaphragm coupling: suitable for servo motor, stepping motorBellows coupling: suitable for servo motorOldham coupling: suitable for general micro motorPlum coupling: suitable for servo motor, stepping motorRigid coupling: suitable for servo motor, stepping motor
