Clamping coupling

   JQ type clamp coupling (HG5-213-65):

    Scope of application:

    The shell coupling is suitable for the connection between the I-type shaft head of the vertical reduction frame and the stirring shaft head of the reactor.

    Structural features:

    The clamping shell coupling uses the two halves of the coupling along the axial part. The clamping shell and the shaft are clamped by the pre-tightening force of the bolts, and the torque is transmitted by the friction between the two.It can be assembled and disassembled without moving in the axial direction.But this coupling can only connect two cylindrical shaft extensions with the same diameter.

    The housing coupling does not need to move axially when assembling and disassembling, so the assembly and disassembly is very convenient. The disadvantage of the housing coupling is the low accuracy of the axis of the two shafts, the structure and shape are more complicated, and the manufacturing and balance accuracy is low. , It is only suitable for occasions with low speed and stable load. Generally, the linear velocity of the outer edge is not more than 5m/s. When the linear velocity exceeds 5m/s, a balance check is required.

    The characteristics of the vertical clamp coupling are similar to those of the clamp coupling, simple structure, easy to assemble and disassemble, suitable for low speed (circumferential speed of XNUMXM/S), no impact, and stable vibration load. It is suitable for occasions The connection of agitator and other vertical shafts.

    Type of coupling:
    Coupling classification: GT type flange coupling, JQ type jacket coupling, SF type three-point coupling, DF type coupling with short section, DT type rigid flange coupling, HE type Welded flange coupling, HL type elastic pin coupling.The characteristics of the coupling: GT type flange coupling; it only transmits torque.Simple structure and good neutrality.It is used for the connection between the shaft head of the reducer and the mixing shaft head on the single fulcrum frame. JQ jacket coupling; good neutrality, easy to disassemble and assemble during use.The radial dimension is small.It can play the role of suspending agitator, generally used for the connection between the stand without fulcrum or the mixing shaft in the tank. SF type three-part coupling; good centering, easy to use and disassemble.There is a gap for replacing the sealing ring in the axial direction. Only the stirring shaft needs to be lowered by 6-8mm during replacement, which is suitable for occasions where the sealing ring needs to be replaced frequently. DF type coupling with short section; used in YDJ and YSJ series racks with good neutrality.Without dismantling the reducer and frame, simply remove the coupling sub-section to remove the lower half of the coupling, frame bearing seat and sealing device. DT-type rigid flange coupling; similar in structure to GT-type coupling, with shaft end stop plate, which can bear axial load.The shaft end of the agitator needs to be machined with a lifting hole. HE type welded flange coupling; simple structure, the coupling disc and the drive shaft are welded together.It is used for the connection between the mixing shafts in the tank, or in similar applications. HL type elastic pin coupling; simple structure, easy to assemble, disassemble and replace.Allows large radial and angular deviations between the two shafts, and has a good shock-absorbing and buffering effect.Applicable to double pivot racks.

   The clamp shell coupling uses two clamp shells split along the axial direction, which are clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling surface, and the flat key is used as an auxiliary connection.

  The performance and characteristics of JQ type-jacket coupling:
  The JQ-type clamp shell coupling uses two clamp shells that are split along the axial direction. The clamp shell coupling spacer has multiple leaf branches, which are like a slider coupling, with a clamp shell coupling structure. Because elasticity has the function of buffering and damping vibration, it is used more in situations with strong vibration.The performance limit temperature of the elastomer determines the use temperature of the coupling. It has good versatility and a wide range of applications. It is easy to use and popularize. One of the outstanding advantages of the coupling is that it is difficult to install as long as it is suitable for axis alignment. This guarantees its zero-gap performance.Different from the slider coupling, the plum blossom coupling is driven by squeezing while the slider coupling is driven by shear.
 The radial and angular axis offset performance of the JQ-type-jacket coupling requires minimizing the working conditions of auxiliary working hours.It also squeezes to make the plum elastic spacer and the shaft sleeves on both sides coincide, so as to realize the connection of the two halves of the slider coupling.
 Good vibration reduction performance, simple structure, stable and reliable work, no noise, no lubrication, simple maintenance, convenient assembly and disassembly, good manufacturability, low cost, can be derived into a variety of structural forms, through the extrusion between the claw and the elastic ring The power is transmitted under pressure, and the relative deviation of the two shafts is compensated by the elastic deformation of the elastic ring, so that the shaft does not need to move axially when assembling and disassembling the clamp coupling, so the assembly and disassembly are very convenient. The shortcomings of the clamp coupling It is the two-axis axis alignment accuracy is low, the structure and shape are more complicated, the manufacturing and balance accuracy is low, and it is only suitable for low speed and stable load occasions. Generally, the linear velocity of the outer edge is not more than 5m/s, when the linear velocity exceeds 5m /s needs to be balanced.In order to improve the balance, the bolts should be installed between the forward and reverse phases.
 JQ type jacket coupling does not have axial, radial and angular compensation performance.The characteristics of the vertical clamp coupling are similar to those of the clamp coupling, simple structure, convenient assembly and disassembly, suitable for low-speed (high peripheral speed of 5M/S), no impact, and stable vibration load occasions. For the connection of vertical shafts such as agitator.All models under the supporting bracket of the worm gear reducer are equipped with a clamp coupling as standard. Due to the simple structure, low cost, and large torque transmission, when the speed is low, there is no impact, the shaft has high rigidity and good centering. .
