Coller Chain Coupling
The roller chain coupling uses the common chain to mesh with two parallel sprockets with the same number of teeth.
Roller Chain Coupling
The roller chain coupling uses the common chain to mesh with two parallel sprockets with the same number of teeth. The main difference between different types of roller chain couplings is the use of different chains. The common ones are double row roller chain coupling, single row roller chain coupling, tooth chain coupling, nylon chain coupling, etc.
Characteristics of roller chain coupling: the performance of double row roller chain coupling is better than that of other types of couplings, and it is widely used at home and abroad. Applied disciplines: Mechanical Engineering (first level discipline); mechanical parts (second level discipline); coupling (third level discipline)
Flange coupling
YL – basic, YLD – medium.
Flange coupling is the use of bolts to connect two flange disc half couplings. The two half couplings are respectively connected with two shafts by keys, so as to realize two shaft connection and transfer torque and motion. The flange coupling has the advantages of simple structure, convenient manufacture, low cost, reliable operation, convenient assembly, disassembly and maintenance, and large transmission torque, which can ensure that the two shafts have high centering accuracy. It is generally used in shafting transmission with stable load, high speed or high transmission accuracy requirements.
Slider coupling
The model is wh.
The structure of the slider coupling is similar to that of the cross slider coupling, but the difference is that the cross slider in the middle is square, and the middle slider is used to slide in the corresponding radial slots on the end faces of the coupling halves on both sides, so as to realize the connection of the coupling halves. Slider coupling noise, low efficiency, wear fast, generally try not to choose, only the use of low speed occasions. The model is wh.
Chain coupling
GL type (without cover), GLF type (with cover)
The chain coupling uses the common chain, and at the same time, it is meshed with two parallel chain wheels with the same number of teeth. The main difference of Chain Couplings with different structures is that they use different chains. The common ones are double row roller chain coupling, single row roller chain coupling, tooth chain coupling, etc. The performance of double row roller chain coupling is better than other structural types of coupling. It has the advantages of simple structure, convenient assembly and disassembly, no need to move the two shafts connected during disassembly, and low cost.
Gear coupling
Gear coupling is composed of inner gear ring with the same number of teeth and flange half coupling with outer teeth. The external teeth are divided into straight teeth and drum shaped teeth. The so-called drum shaped tooth is to make the external teeth into a spherical surface with the center of the spherical surface on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum shaped tooth coupling can allow larger angular displacement .
When the gear coupling is working
The two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer teeth periodically make relative axial sliding, which will inevitably lead to tooth wear and power consumption. Therefore, the gear coupling needs good lubrication and sealing state.
Universal coupling
There are many kinds of universal couplings, including cross universal coupling and ball cage universal coupling. The common feature of universal couplings is that the angular compensation is large. The angle between two axes of universal couplings with different structures is different, generally between 5 and 45 degrees.
It is mainly divided into: SWC type universal coupling, SWP type universal coupling, SWZ type universal coupling, WSD type universal coupling, WS type universal coupling, WSH type sliding bearing universal coupling.
Advantages of roller chain coupling
The advantage of GL type roller chain coupling is that it can transmit motion and power when the center distance between two shafts is far. It can work under the condition of low speed, heavy load, high temperature and heavy dust. It can ensure accurate transmission ratio, high transmission power and small force acting on the shaft. High transmission efficiency.
