Jiangsu SWPF type large telescopic single universal coupling

The common feature of SWPF type large telescopic single universal joint is that the angular compensation is large, and the angle between the two axes of universal joints of different structure types is different, generally ≤5°-45°.The universal coupling utilizes the characteristics of its mechanism to make the two shafts not on the same axis, and when there is an angle between the axes, it can realize the continuous rotation of the connected two shafts, and transmit torque and motion simultaneously.The universal coupling is characterized by large angular compensation capability, compact structure and transmission. SWPF type large telescopic single universal coupling is a commonly used coupling.Utilizing the characteristics of its structure, it can make two shafts that are not on the same axis or that have a large angle of axis or that have a large axial movement continue to rotate at equal angular speed, and transmit torque and motion simultaneously.Can be widely used in metallurgy, lifting, engineering transportation, mining, petroleum, shipbuilding, coal, rubber, papermaking machinery and other heavy machinery industries to transmit torque in mechanical shafting.

The main features of SWPF type large telescopic single universal coupling are:

1. Has a large angle compensation capability.

2. The structure is compact and reasonable. The SWC type uses an integral fork to make the carrier more flexible.

3. Large carrying capacity.Compared with other types of couplings with the same rotating diameter, the torque transmitted by it is larger. This is superior to the range of matching mechanical equipment with restricted rotating diameter.

4. Transmission.Its transmission efficiency is 98-99.8%, which is used for high-power transmission and energy saving.

5. Stable transportation, low noise, easy assembly and disassembly and maintenance.

For severe impact loads or transmissions that require shafting torsional vibration, tire couplings and other couplings with high elasticity can be selected. The working speed of SWPE type (long type with telescopic flange) cross-shaft universal coupling and the amount of centrifugal force caused.For high-speed drive shafts, couplings with high balance accuracy should be selected, such asDiaphragm couplingEtc., it is not appropriate to use eccentric slider couplings.The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.The general power machine is mostly connected with the working machine by means of a coupling.

In order to overcome the shortcomings of the double cross shaft universal coupling, the length of the intermediate shaft in Figure 1 is shortened to 0, that is, the intermediate shaft is eliminated, and the two cross shafts are correspondingly changed into a cross shaft and a cross ring structure, then the ring fork type Constant angular velocity universal coupling.In order to meet the characteristics of uniform motion, it is necessary to add a set of indexing mechanism, which is similar to the lever-type indexing mechanism of the ball cage universal coupling, which achieves that the movement plane of the universal coupling is the main force transmission point. , Constant velocity transmission conditions of the angular bisecting surface of the driven shaft.

The analysis shows that when the ring-fork universal joint has an indexing error, it will have an impact on the constant angular velocity, but its effect is small, so the constant angular velocity of the ring-fork universal joint is acceptable.The uniform velocity of the ring fork universal joint is close to that of the RzEPPA ball cage universal joint.
