Nowadays, with the continuous reform of mechanical equipment, the coupling, which is the main transmission component of mechanical equipment, has also undergone a series of reforms to meet the requirements of various equipment for transmission parts.Such as the combination of shaft hole style, size change and surface oxidation treatment, mainly
Select the structure of the coupling according to the needs of the supporting host. When the coupling is used in conjunction with the brake, a coupling with a brake wheel or a brake disc should be selected; when overload protection is required, the coupling should be selected; When connecting with flange, flange type should be selected; long distance
The plum blossom coupling is a widely used coupling, also called a claw coupling, which is composed of two metal claw discs and an elastic body.The two metal claws are generally made of No. 45 steel, but aluminum alloys are also useful when load sensitivity is required.
Plum coupling is a kind of elastic coupling, which is widely used in the transmission field of pulverized coal machine. It is widely used by customers, such as large amount, simple and cheap to use.The working principle of the plum blossom coupling is to install a whole plum blossom-shaped elastic ring on two semi-couplings with the same shape.
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.
