Reed coupling features installation instructions

　　The reed coupling is a kind of coupling, and its service life is also very long. Therefore, what is the product description of the reed coupling? The following is the coupling of the content brought by the editor, I hope you can get something!

　　Reed coupling prevents the elastic cushion from losing its cushioning effect

　　Reed couplings are widely used in coal mine installations.The adjustment of the assembly end and the gap directly affects the driving torque of the motor.The gap can effectively prevent the elastic cushion from losing its buffering effect and prevent the electric cleaner or reducer from overheating.Relevant standards stipulate that the clearance at the assembly end of the coupling is 2-4 mm.

　　Since small repair items are produced by the same manufacturer, the size of the coupling is slightly different.If the end and gap of the coupling are accurately measured before assembly, then determining the assembly position may lead to reentry.In the case of large torque transmission, the coupling and shaft are too large and difficult to return.Taking the plum-shaped elastomer coupling used in the Szzh 80/250 medium double-chain scraper conveyor as an example, the plum-shaped elastomer coupling is briefly explained.End and gap adjustment force method.

　　Couplings are used more and more widely, but the installation details of couplings are not very clear in many occasions, resulting in high coupling loss rate and great economic losses.The installation technique of the coupling is as follows.

　　(1) Before installation, first check whether the prime mover and the working machine are prime movers, whether there are wrapping paper on the surfaces of the two shafts, whether there are debris in the inner holes of the two halves of the coupling, and whether the hole-edge coupling is inside There is debris; if there should be a shaft, clean the half coupling with a fine file.On this basis, it was investigated whether the diameter and length of the inner holes of the two semi-horizontal machine tools were consistent with the diameter and length of the prime mover, the processing machine tool, and the extension of the shaft.Under normal circumstances, the length of the half coupling between the prime mover and the working machine should be less than 10%.

　　(2) In order to facilitate installation, preheat the two half couplings in the 120-150 incubator or oil tank to increase the inner hole size and facilitate installation.After installation, ensure that the shaft head does not protrude from the half coupling part, so it is flush.Detect the distance between the two halves of the coupling:

　　The average reading of 3-4 points on the inner side of the half coupling flange and the sum of the measured dimensions of the extension section and the two diaphragm groups should be controlled within the range of 0-0.4 mm.

　　(3)正确：用刻度器检测耦合的两个半边的法兰截面和外圈。法兰外圈小于250mm时，打数值不得大于0。o 5mm;法兰外圈大于250mm时，打数值不应大于0.08mm。

　　During the assembly process, appropriate measurement standards should be selected to avoid amplifying measurement errors. Generally, the combination of the motor and the connecting plate should be selected as the measurement reference for the semi-coupling of the motor.The measurement data of the half coupling of the reducer generally select the combination of the connecting cover and the connecting plate, and adjust the end and the gap of the plum elastomer coupling. The axial gap of the half coupling is 8≤b-(a≤m ).

　　among them:

　　The distance between the bottom of the motor half coupling of the motor and the connecting plate combination

　　h is the connecting cover and connecting plate combined with the top of the reducer half coupling (clutch), and the distance m is the thickness of the connecting plate

　　At the same time, when assembling the motor half coupling, the distance t between the step of the motor output shaft end and the bottom of the motor half coupling must be considered, because the value of t is a direct factor that affects the assembly position of the half coupling.In the lower adjustment force method, it is discussed whether the half coupling is to increase the distance pad or the inner end face, and the daily t value is adjusted.

　　The reed coupling has good damping characteristics, good elasticity, large changes in elastic elements, compact and reliable structure, but high price, suitable for large load changes.Torque vibration shafting is mainly used in diesel power devices such as ships, diesel locomotives, diesel generator sets, heavy vehicles, and industrial diesel power devices to adjust the vibration frequency of the torque vibration of the shaft drive system to reduce the amplitude of resonance.The elastic element coupled by the elastic resistance reed is composed of a set of reeds.The reeds are distributed radially along the radial direction.One end of each group of reeds is a fixed end, which forms a fixed connection on the supporting block, and the other end is a free end, which forms a movable connection with related parts.

　　When the coupling transmits torque, the movable end of the reed contacting the spline shaft is bent relative to the fixed end, so that the two half couplings are twisted at an angle relative to each other.In order to improve the buffering and damping effect of the coupling, the cavity between the reeds of each group is filled with lubricating oil. Under the action of variable load, the reeds are bent and deformed to form a pressure change in the oil cavity and force the lubricating oil to pass through the reed The cracks on both sides of the sheet flow from one side to the other.A great viscous friction damping is produced.The coupling has good damping performance, and the lubricating oil can also reduce the friction and wear directly generated on the reed due to the bending and deformation of the reed.

　　The content of the reed coupling introduced above, I hope it can be helpful to you. Our website also organizes more information about it. If you want to learn more, please remember to collect it.
