HangzhouJS type housing radial mounting type coupling

The structure and precautions of JS type casing radially mounted coupling

The JS type housing radial mounting type coupling is a structural metal.It relies on serpentine springs to transmit torque.The serpentine coupling is a shaft coupling transmission component in today's mechanical field, and it is also a very versatile shaft coupling transmission component.

There are nine types of serpentine spring couplings, namely JS housing radial mounting type (basic type), J housing axial mounting type, JSS double flange connection type, JSD single flange connection type, and SJS connection middle Shaft type, JSG high speed type, JSZ wheel type with brake, JSP type with brake disc, JSA type, etc.

The main structure of the serpentine spring coupling is composed of two half couplings, two half outer covers, two sealing rings and a serpentine spring sheet.It transfers torque by embedding the serpentine spring into the tooth slots of the two coupling halves, and the coupling uses serpentine spring sheets to be embedded in the tooth slots of the two coupling halves to realize the link between the driving shaft and the driven shaft.During operation, the driven end is driven by the axial force of the active end tooth facing the snake spring to transmit torque, which largely avoids the occurrence of resonance phenomenon and the elastic variable generated by the reed when transmitting torque , So that the mechanical system can obtain a better damping effect, with an average damping rate of more than 36%.

Precautions and application of JS type casing radial mounting type coupling:

XNUMX. Installation and alignment, control reasonable deviation

(1) Correction of the gap and angular deviation between the two-lobe couplings. When installing, measure the gap between the two-lobe serpentine spring couplings every 90°, and the difference between the large value and the small value does not exceed 0.38 mm.

(2) Correction of radial deviation.Put a ruler on the two-part coupling, measure it every 90°, and check with a ruler, the radial deviation does not exceed 0.38mm.

XNUMX. Application of Snake Spring Coupling

(1) It is suitable for medium and high-power transmission shafts connecting two coaxial lines, with compensation for the relative deviation of the two shafts, vibration reduction, and cushioning performance. The working temperature is -30℃~+150℃, and the nominal rotation is transmitted. Moment is 45~800000N.m.

(2) Mainly used in rock crusher, crank reciprocating motion, reducer, metallurgy, mining, hoisting machinery, etc.

(3) The shaft transmission of other various machinery and equipment can be applied wherever a motor is connected to the staff, the motor is connected to the reduction box or the shaft is connected to the shaft.

The JS-type casing radially mounted coupling uses a serpentine spring leaf to axially embed the two halves for more than 36%.The serpentine spring leaf of the trapezoidal cross-section is made of spring steel, which has undergone strict heat treatment and processing. It has good mechanical properties, so that the service life of the serpentine spring coupling is much longer than that of the non-metal elastic element coupling (such as elastic sleeve). Column pins, nylon rod pin couplings) have greatly increased.

JS type housing radial installation coupling is used in a variety of different host products, and the surrounding working environment is more complicated, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, salt water Conditions such as, radiation, etc., are one of the important factors to consider when choosing a coupling.

The tooth surface contacted by the reed of the JS type casing radially mounted coupling is arc-shaped, and the size of the contact surface changes with the size of the transmitted torque, so it can withstand large load changes. The short-term The overload capacity is 2 to 3 times the rated torque, and the transmission efficiency reaches 99%.
