The life of the GCLD drum gear coupling depends on the contact strength

Publication time: November 2016, 05【L Small

    The bearing capacity and life of GCLD drum gear couplings depend on the contact strength: for flexible and drum gear couplings, some are lubricated with grease.That is, when the coupling is working, it can be lubricated due to the squeeze of grease.When assembling, grease is applied to ensure sufficient lubrication inside.The grease used in the high-speed device ensures that the oil and soap will not separate under the action of centrifugal force, otherwise the coupling oil leakage will reduce the lubrication effect.At the same time, it requires multi-efficiency, that is, it must have heat resistance, and it must have a certain degree of cold resistance when working at low temperatures.The lubrication of spring-type couplings mostly uses grease.When assembling, the grease fills the gap between the grid plates, and the grease is not leaked after being bandaged.Regular inspections are required during work, and the refilling grease is generally lithium-based grease.Pin couplings and flexible chain couplings generally use lithium-based grease.The universal main coupling is also lubricated with grease. It can also be greased frequently without stopping the machine. Generally, grease products with good water resistance and strong adhesion are required.

  How to disassemble and assemble the pulley or coupling of the motor:

  1. When disassembling, mark the position between the pulley or coupling and the rotating shaft first, screw the factory fixing screws and pins, and then slowly pull it out with a puller.If you can't pull it out, you can pour some kerosene into the inner hole and pull it out.If it still can't be pulled out, use rapid fire around the pulley or coupling to quickly heat it. At the same time, wrap the shaft with a damp cloth and continuously pour cold water to prevent heat from being introduced into the motor.

  2. When assembling, first use a fine iron emery cloth to smooth the shaft hole of the shaft, pulley or coupling, align the pulley or coupling with the keyway and set it on the shaft, and use wrought iron or hardwood block to pad one end of the key. Gently tap the key into the slot.The key should be properly tight in the groove. Too tight or too loose will damage the key and groove, and too loose will cause the belt to slip or vibrate.The bearing capacity and life of the drum gear coupling depend on the contact strength, while the radius of curvature of the tooth surface and the tooth engagement angle directly affect the contact strength.

  The GCLD drum gear coupling has the characteristics of compensating the above displacement, reduces the additional load caused by the axis displacement, improves the working stability and reliability of the transmission device, and thus prolongs the service life of the transmission device. The characteristic of JZMJ diaphragm coupling is a bit like a bellows coupling. In fact, the way the coupling transmits torque is similar.The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to 1.5 degrees of deviation, while generating a lower bearing load in the servo system. JZMJ diaphragm couplings are often used in servo systems. The diaphragm has good torque rigidity, but it is slightly inferior to bellows couplings.

  GCLD drum gear coupling is a new type gear coupling developed on the basis of spur gear coupling, digesting and absorbing foreign advanced technology.It is composed of an outer gear sleeve with a drum-shaped tooth thickness and a matching inner gear ring that connects two shafts. It is suitable for heavy load and two-axis transmission that requires axis displacement compensation.Under normal circumstances, it is required that the two shafts to be connected are completely concentric, and it is impossible to continue to maintain the concentric state during operation. Because of installation errors, bearing wear, force deformation, foundation sinking, etc., the axis produces radial, Angular displacement.On the other hand, the JZMJ diaphragm coupling is very delicate and can be easily damaged if it is misused or improperly installed during use.Therefore, it is very necessary to ensure that the deviation is within the tolerance range of the normal operation of the coupling.Choosing the right coupling is a key step to make good use of the coupling. You have to consider what type of coupling to choose in the design stage.The power of the power machine in the transmission system should be greater than the power required by the work machine.
