Henan JSA type serpentine spring coupling

JSA type serpentine spring coupling is a kind of metal elastic coupling with reasonable structure. It relies on serpentine springs to transmit torque. The serpentine spring coupling is a shaft coupling transmission part, and it is also a very versatile shaft. There are nine types of serpentine spring couplings for connecting transmission components, namely JS shell radially mounted (basic) serpentine spring couplings, JS B shell axially mounted serpentine spring couplings, and JSS Double flange connection type serpentine spring coupling, JSD single flange connection type serpentine spring coupling, SJS connection intermediate shaft type serpentine spring coupling, JSG high speed type serpentine spring coupling, JSZ belt system Moving wheel serpentine spring coupling, JSP serpentine spring coupling with brake disc, JSA serpentine spring coupling, etc.

The main structure of the JSA serpentine spring coupling is composed of two half couplings, two half outer covers, two sealing rings and serpentine spring plates.It transfers torque by embedding the serpentine spring into the tooth grooves of the two coupling halves, and the coupling uses serpentine springs to be embedded in the tooth grooves 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 and the elastic variable produced by the reed when transmitting torque. , So that the mechanical system can obtain a better damping effect, with an average damping rate of over 36%.

Installation and alignment, control reasonable deviationSerpentine spring couplingAlthough a large installation deviation is allowed, it should also be within the specified value during installation. (1) When aligning the gap and angular deviation between the two couplings, every 9°.Measure the gap value between the two-lobe coupling, and the difference between the larger value and the smaller value does not exceed 0 mm. (38) Alignment of radial deviation.Use a ruler to place it on the two-part coupling, every 2°.Measure once and check with a feeler gauge, and the radial deviation does not exceed 9 mm. 1 It is better to choose a suitable grease with an oil injection point temperature of ≥0℃, which can resist the action of centrifugal force, has separation stability, no impurities, and does not corrode carbon steel and nitrile rubber. 38 Filling with a sufficient amount of grease Adequate lubrication is important to the work of the coupling, and it is recommended to check once a year.Use a dry oil gun to inject grease until there is excess grease overflow in the hole. 2 Control the working environment temperature of the coupling, generally at 150～3℃.
