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.
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 type plum blossom coupling is not suitable for high-precision servo transmission applications.
The elastic coupling is cut with a metal round bar wire, and the commonly used materials are generally aluminum alloy, stainless steel and engineering plastics.The elastic coupling uses two grooving systems, parallel or spiral, to adjust to accommodate deviations and transmit torque.
The plum blossom coupling is suitable for connecting two coaxial transmission shafts. It has the functions of compensating the relative deviation of the two shafts, buffering, damping, and adapting to general occasions.
The gap between the bolt fitting section of the diaphragm coupling and the flange hole fitting section is generally based on the bolt diameter of 0.20mm ~ 0.30mm. This fitting section plays a key role in transmitting torque. If the gap exceeds the standard, replace it.
The diaphragm coupling alignment tool includes a guide seat with a V-shaped groove at the bottom, a groove opening to one side and the top surface in the middle of the upper seat body, and a V-shaped groove at the bottom radially Intersecting and penetrating observation slots; measuring plate, L-shaped structure, thickness and guide seat
Diaphragm couplings rely on metal diaphragms to transmit torque and absorb deformation caused by misalignment. There is no relative movement between parts, no friction/wear, and no lubrication is required, which is in line with the development direction of oil-free process equipment.
The slider coupling is also known as the metal slider coupling. Its slider is ring-shaped and made of steel or alloy. It is suitable for transmissions with low speed and large transmission torque. The slider coupling and the cross The structure of the sliding block coupling is similar, the difference is that the middle cross block is a square sliding block.
The clamping shell coupling cannot be processed due to the long shaft hole, so make a lifting ring in the middle of the axial position to prevent axial movement, and secondly for the accuracy of the shaft hole.
