Explanation of the same number of couplings with different center heights

Couplings with different center heights, same numbers and different powers (the test machine is a high-power motor, and the tested machine is a low-power motor); the same center height is different and the same power motor; the different center height is different and the same power motor; the same center height is different Changes in the number of motors with different powers; the test machine is a high-power motor, and the test machine is a low-power motor with different center heights and different numbers of different power motors.

The electronic prototype motion mechanism simulation generates motion constraint connections by calling a large number of motion constraint connection methods provided by the system, and then realizes the motion simulation of the electronic prototype.All moving parts of the motion simulation need to be in the same level of the structure tree, and belong to the same level relationship.When the electronic prototype motion mechanism simulation inserts the above-mentioned sub-assembly part, the system will treat the part as a single rigid body, so that the 83 parts of the entire model become 11 moving parts.

The metal diaphragm coupling has all the advantages of the rubber element coupling, and it also has the advantages of small axial thrust, good service life and vibration reduction, which determines the accuracy of the transmission power.When transmitting the same amount of torque, the metal diaphragm coupling produced by the coupling manufacturer has the advantages of smaller size, lighter weight, convenient maintenance and cost saving than other couplings.The selection of the coaxial centerline and the surface are located on the same part entity. If you want to select the two end faces of the bearing sleeve and the baffle as the contact surface, select the centerline of the bearing sleeve and the baffle when selecting the coaxial centerline, otherwise the mouse It will not be possible to select the end faces of the bearing sleeve and the baffle.

Considerations in power matching The motor under test can have corresponding fluctuations in power matching requirements during the test. The power of the tested machine can float between 70% of the power of the test machine, and different types of motors can be dragged. The situation is a matching test between the same center height, the same power and several levels.According to the test situation and test standard analysis of the test station, P=(170%)P different kinds of motors are affected by the comprehensive factors of the motor center height, shaft diameter, number of motors and power during the towing test. In order to determine the test quality, Test the quality and simplify the design of the coupling.Two identical motors are driven in pairs; two different motors are driven in pairs, with the same center height and the same number of different power motors.

Gear couplings are difficult to process and easily made into scrap parts.Because the outer circle of the inner gear ring is 4350mm, the inner circle is 330mm, one side is 10mm thick, and it already has 12 holes, it is difficult to process, and the entire set of couplings will be scrapped once the process is not good. Shaft, and may delay production at the same time.It requires manual disassembly, transportation, processing, and assembly costs. The specific method is to use a through hole at the root of the inner ring gear, and there is no longer a small circle of the same size.The outer circle of the bolt hole of the inner gear ring is enlarged to increase the diameter of the bolt of the retaining ring, which is easy to install on site.The sealing box is made into two halves by wire cutting technology, which reduces the gap and improves the sealing performance.It is cumbersome to install and fix the seal on site.

The internal gear ring of the gear coupling adopts a processing improvement method: after the twisted bolt holes are marked, the entire coupling is disassembled.The inner gear ring of the gear coupling is cut into two parts containing teeth and a sealing groove where there are no teeth. Holes and taps 12-M6 are drilled in the tooth-containing part, and the sealing groove part is drilled 12-7.The sealing groove part and the sealing baffle are milled into two halves with a milling machine.When replacing the motor, after assembling the motor, the motor shaft sleeve 1, the brake wheel and the inner gear ring (including the gear part), insert the outer gear shaft sleeve in parallel, and then use the seal groove part and the seal baffle in 12-35 The hex bolts are fixed together to complete the motor replacement.

The clearance of the sealing process is large, and the sealing performance is poor.After the improvement, it has been successfully put into use after the improvement. The effect has been good. It not only shortens the online maintenance and replacement time, but also reduces the labor of workers to repair and replace spare parts. It also saves processing costs and brings obvious economic benefits.Generally, couplings produced by many domestic manufacturers are not interchangeable.At present, most of the twisted bolt holes of the shaft sleeves of the drum-shaped gear couplings are assembled by using the method of drilling and reaming, and then marking and checking into the seat.Couplings manufactured in this way are not interchangeable.

Therefore, when replacing the motor, the steps for removal are to remove the twisted bolts, remove the motor and the motor shaft sleeve, and remove the brake wheel; the old inner gear ring is destroyed and removed by gas cutting.The external gear shaft is sleeved on the shaft head of the reducer. Due to the large shaft diameter of 110mm, on-site space and maintenance time constraints, it is generally not replaced.Therefore, the treatment of installing a new motor is to assemble the motor, motor shaft sleeve, brake wheel and inner gear ring. After the overall hoisting, the inner and outer gear gaps allow the inner gear ring to be inserted into the outer gear shaft sleeve in parallel. The structure is restricted, and the inner gear ring is improved.
