Product Description
Product Details
A coupling is a mechanical component that is used to firmly connect the driving shaft and driven shaft in different mechanisms together, rotate together, and transmit motion and torque. It is also sometimes used to connect shafts and other parts (e.g. gears, pulleys, etc.). It usually consists of 2 parts, which are connected by a key or clamping fit, respectively, and fastened at the 2 shaft ends. Couplings can compensate for deviations (including axial, radial, angular or combined offset) between 2 shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation, as well as shock and vibration absorption. The most commonly used couplings have been standardized or normalized. In general, it is only necessary to select the type of coupling correctly and determine the type and size of the coupling. If necessary, check and calculate the carrying capacity of the vulnerable and weak links; When the rotational speed is high, it is necessary to check the centrifugal force on the outer edge and the deformation of the elastic element for balance detection.
Couplings are used to connect shafts in different mechanisms, mainly by rotation, thus transferring torque. Under the action of high-speed power, the coupling has the function of buffering and damping, and the coupling has good service life and working efficiency.
The function of the coupling:
a device that connects 2 shafts or shafts with rotating parts and rotates together in the process of transmitting motion and power and does not break away under normal circumstances. Sometimes, it is also used as a safety device to prevent the connected parts from bearing excessive loads and play the role of overload protection. The coupling is installed between the active side and the passive side of the power transmission, which plays the role of transferring torque, compensating the installation deviation between shafts, absorbing equipment vibration and buffering load impact. One of the functions of couplings is to absorb and compensate for deviations between shafts through their own deformation. The greater the elasticity, the stronger the ability to absorb the deviation; The less flexibility you have, the less ability you have to absorb deviations. In general, the deviation between the shaft and the shaft can be divided into the following 3 aspects: The connection between the coupling and the peripheral equipment is achieved by inserting the shaft of the device into the shaft hole of the coupling.
1. The role of the coupling is to connect the 2 shafts in different mechanisms (drive shaft and driven shaft) to rotate and transmit torque together, and some couplings also have the role of buffering, damping and improving the dynamic performance of the shafting.
2. Eliminate the inertia of the radial force, connect the motor spindle with the load, and use a coupling to weaken the starting power when the motor starts.
3. Power conduction, transmission of power and torque (improve the performance of the transmission system)
4. Different degrees of vibration reduction and buffering
5. Disconnect when the load is too large to play a protective role
6. Good for maintenance
7. Change the drive direction
8. Concentricity correction (different degrees of axial, radial and angular compensation performance)
The types of couplings
Bellows coupling
The bellows coupling is composed of 2 hubs and thin-walled bellows that are welded or bonded together. The input end of the coupling structure is a clamping structure, and the pre-tightening force is generated by clamping screws, and the power input shaft is firmly connected with the clamping hoop. Flexible and rigid stainless steel bellows have the ability to correct radial, axial and angular deviations, transmit torque with zero backlash, and have different bushings designed to meet different equipment requirements.
A plum coupling
Plum coupling is a widely used coupling, elastomer is a balance accessory, can zero back backlash transfer torque and shock absorption. The different types of elastomers determine the characteristics of the entire drive system. Zero back backlash is achieved through a pre-pressure between the 2 coupling bushing and the elastomer. Its elastomer is usually composed of engineering plastics or rubber. Because elastomers have the function of buffering and reducing vibration, they are widely used in the case of strong vibration.
Safety coupling
The safety coupling mainly relies on the spring force and works with the shape, which can protect the adjacent drive components from damage caused by overload. Divided into synchronous type, stepping type 60°, failure protection type, closed. Features of a special butterfly spring system. No torque transfer is possible until the torque control nut is linked to the butterfly spring to apply pressure. The service life of the safety coupling is largely determined by the speed at which the coupling is disengaged and the holding time of the coupling. The safety coupling is not worn when it is engaged, does not require maintenance, and does not require additional refueling.
Rigid coupling
The rigid coupling is actually a torsional rigid coupling. Even under load, there is no turning clearance. Even if there is a deviation that creates a load, the rigid coupling is still rigid to transmit torque. Rigid couplings need to be used to connect 2 shafts in strict alignment without relative misalignment, so they are used less in motor test systems. Of course, if the relative displacement can be successfully controlled (the alignment accuracy is high enough), rigid coupling can also play an excellent role in the application. In particular, the small size rigid coupling has the advantages of light weight, ultra-low inertia and high sensitivity. In practical applications, rigid couplings have the advantages of maintenance-free, ultra-oil resistance and corrosion resistance.
Long shaft coupling
The standard length of the long-shaft coupling is up to 6 meters, and no intermediate support is required. The 2 ends are connected by high-performance stainless steel or high-strength aluminum, and the middle pipe is made of different materials such as steel, aluminum or carbon fiber. The allowable deviation range, speed and torque of the standard model should be reduced by 30%. The allowable working speed depends on the total length of the joint shaft and can also be adjusted according to demand.
Diaphragm coupling
Diaphragm couplings transfer torque by friction and diaphragm assembly, so there are no stress concentrations, backbacklash and micro-displacement that occur when torque is transferred through shoulder bolts. It has a near unlimited service life and increases the torsional rigidity of the individual components of the complete coupling, which can compensate for a variety of combined shaft assembly errors as a percentage of the total allowable error value listed in the data sheet. The sum of the percentages of the 3 errors cannot exceed 100%.
