     The serpentine reeds of the serpentine spring coupling and the curved tooth surfaces on the outer gear shaft sleeve are difficult to manufacture due to their complex shapes.When the snake reed is manufactured, not only a large number of special forming molds are required, but also the dimensional accuracy is difficult to meet the design requirements.The formation of the snake spring is achieved by using a mold under heating, and then heat treatment. During the heat treatment, the arc of the reed is prone to problems such as micro cracks.The possible accidents of the coupling are: 1. The axis of the coupling is skewed and the coupling does not advance: In order to prevent such accidents, except for the alignment of the axis, the position of the coupling hole and the shaft, and the position of the striker Do it right when...
    Compared with the gear coupling, the diaphragm coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient to manufacture, and can partially replace the gear coupling.Diaphragm couplings have been widely used in developed countries in the world. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.The diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are interlaced with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into rod type and different shapes. The whole piece.The diaphragm coupling needs to be maintained during the effective use cycle...
     The plum-shaped elastic coupling has the advantages of small radial size and moment of inertia, no gap, good damping and buffering effects, and strong axial, radial and angular compensation capabilities. It is widely used in metallurgy, petroleum, chemical industry, etc. Lifting and other industries, especially medium and high speed working conditions with frequent starting and forward and reverse rotation.Although the plum blossom flexible coupling has good misalignment compensation capabilities, the misalignment of the coupling still produces additional force and torque on the rotor and bearing system, and these additional forces often bring serious consequences.With the advancement of science and technology, the rotor system is gradually developing in the direction of high speed and heavy load...
     Before disassembling the coupling, it is necessary to make some marks for the coordinated positions of the various parts of the coupling for reference when reassembling.For couplings used in high-speed couplings, the coupling bolts are weighed, and the transmission accuracy of the coupling must be clearly marked and cannot be mistaken.When disassembling the diaphragm coupling, generally disassemble the connecting bolt first, and the working environment.Because a layer of grease, corrosion products and other deposits are deposited on the surface of the thread, the bolt is not easy to disassemble, especially for the heavily corroded bolt, it is very difficult to disassemble.The disassembly of the connecting bolt must choose a suitable tool, because the bearing surface of the outer hexagon or inner hexagon of the bolt has been...
     Reasons for damage to the drum gear coupling: 1. When the coupling is used, the equipment in the shafting system, such as diesel engine, gearbox, shafting, and high-elasticity coupling, must interact with each other in design and use. In addition, the level of design and manufacturing is relatively high, and the quality of the ship designed in this way is also high. 2. The main reason is that the vibration damper of the main engine has sunk, which makes the shafting of the coupling appear asymmetry, thereby increasing the additional torque, which makes the highly elastic coupling in use When there is a breakage accident due to fever. 3. Because the use range of couplings is relatively wide, in...
    The plum blossom elastic coupling has a simple structure, a small number of parts, a small radial dimension, and no need for lubrication; the elastic element has a high load-bearing capacity under pressure.Except for the double-flange plum blossom elastic coupling, the half coupling must be moved axially when replacing the vulnerable plum blossom elastic parts.This kind of coupling has a certain ability to compensate the relative offset of the two shafts.The cross-section of the plum petals of the plum elastic coupling is usually circular, which can improve the uniformity of the load distribution on the working surface, and can transmit larger torque, but the elasticity is slightly reduced.It can also be made into a rectangle or fan shape.When the coupling is working, the plum petals are squeezed, and only half of the plum petals carry work.Quincunx...
