Description

Technical Field

[0001] The invention relates to the technical field of couplings, and in particular to a high-performance drum gear coupling. Background Art

[0002] Couplings, also known as couplings, are mechanical parts used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. They are sometimes also used to connect shafts with other parts, such as gears and pulleys. The coupling is composed of two halves, which are keyed and fastened to the two ends of the shaft, and then connected in some way. The drum gear coupling is a rigid-flexible coupling with the ability to compensate for radial, axial and angular axis deviations. Compared with the straight gear coupling, it has the advantages of compact structure, small turning radius, large load-bearing capacity, high transmission efficiency, low noise and long maintenance cycle.

[0003] When the existing drum gear coupling is in use, some iron debris will be generated due to the friction caused by the transmission between the outer drum gear and the inner gear ring. These debris will accumulate on the outer drum gear and the inner gear ring, resulting in greater friction between the outer drum gear and the inner gear ring, causing greater damage to the outer drum gear and the inner gear ring. The iron debris cannot be flushed out during use, thereby affecting the service life of the coupling. Summary of the invention

At this time, the oil inlet pipe 31 drives the permanent magnet plate 35 to rotate, and the permanent magnet plate 35 is stirred at the bottom of the mounting frame 6. At this time, the oil will flow along the permanent magnet plate 35 to the oil inlet port 34 on the oil inlet pipe 31. At the same time, when flowing, iron filings mixed in the oil will be adsorbed by the permanent magnet plate 35, so that the iron filings in the lubricating oil are adsorbed and filtered.

Then, the cleaning door 42 at the bottom of the installation frame 6 is opened, and the iron filings on the permanent magnet plate 35 are cleaned. After cleaning, the extracted oil is poured back into the installation frame 6, so as to realize portable cleaning of the debris and reuse of the lubricating oil.

[0029] The working principle of the present invention is as follows: the shaft sleeve 2 is driven to rotate by the rotation of the coupling during operation, and the shaft sleeve 2 drives the first transmission gear 21 to rotate.

At this time, the oil will flow along the permanent magnet plate 35 to the oil inlet port 34 on the oil inlet pipe 31. At the same time, when flowing, iron filings mixed in the oil will be adsorbed by the permanent magnet plate 35, so that the iron filings in the lubricating oil are adsorbed and filtered. Then, the purified oil enters the connecting pipe 32 through the oil inlet pipe 31, and then enters the oil pump 11 through the connecting pipe 32, so as to realize self-cleaning and filtration of the lubricating oil and realize the recycling of the lubricating oil.

[0031] After long-term use, there are many iron filings on the permanent magnet plate 35 and they need to be cleaned. At this time, the electromagnetic valve on the oil outlet pipe 12 is closed, and the electromagnetic valve on the oil drain pipe 41 is opened. Then the oil is discharged into the oil barrel through the oil drain pipe 41 for storage. Then, the cleaning door 42 at the bottom of the installation frame 6 is opened, and the iron filings on the permanent magnet plate 35 are cleaned. After cleaning, the extracted oil is poured back into the installation frame 6, so as to realize portable cleaning of the debris and reuse of the lubricating oil.
