Shaft manufacturers analyze various types of coupling lubrication maintenance methods

Published: 2020-04-15

     Good lubrication of the coupling is to work, it is a way to slow down the wear, and it is also an important way to improve the life of the coupling. Because of the diversification of coupling models, its characteristics and performance are also different. TodayCoupling manufacturersThe editor will give you a detailed introduction to the lubrication methods of different types of couplings: 　

  　Double-head gear coupling: The circumferential speed is about 60m/s, lubricated with No. 0 or No. 1 grease, the amount is to fill the coupling, the grease change cycle is 6-12 months, and the lubricant is required to have good adhesion.Coupling manufacturersThe sealing requirements are not strict; the circumferential speed is about 60m/s, and it is lubricated with N150 and N220 gear oils, and the amount is half of the capacity of the coupling, so that there is no oil leakage when stationary. The oil change interval is 12 months. The sealing requirements are not Strict; The circumferential speed is about 150m/s, and it is lubricated with N150 and N220 gear oil. It requires sufficient flow to pass through the coupling continuously in the axial direction without sealing. 　

　 Single-head gear coupling: The peripheral speed is about 60m/s, and it is lubricated with No. 0 or No. 1 grease. The amount is to fill the coupling. The grease change cycle is 6-12 months. The lubricant is required to have good adhesion.Coupling manufacturersThe sealing requirements are not strict; the circumferential speed is about 60m/s, lubricated with N150, N220 gear oil, the amount is half of the capacity of the coupling, so that there is no oil leakage when stationary, the oil change interval is 12 months, ordinary mineral oil, The sealing requirements are not strict; the circumferential speed is about 30m/s, lubricated with No. 0 or No. 1 grease, the amount is to fill the coupling, the grease change cycle is 6 months, the lubricant is required to have good adhesion, and the sealing requirements are not strict . 　　

    Jaw-type coupling: peripheral speed is about 150m/s, lubricated with N150, N220 gear oil,Coupling manufacturersSufficient flow is required to pass through the coupling continuously in the axial direction without sealing. 　　

    Spring leaf coupling: The peripheral speed is about 30m/s, lubricated with No. 1 grease, the amount is to fill the coupling, the grease change cycle is 1000 hours, and the sealing requirements are not strict. 　　

    Disc spring coupling: The peripheral speed is about 60m/s, lubricated with No. 2 or No. 3 grease, the amount is to fill the coupling, the grease change cycle is 12 months, and the sealing requirements are not strict; the peripheral speed is about 150m/ s, lubricate with N150, N220 gear oil, and require sufficient flow to continuously pass through the coupling in the axial direction. 　　

    Cross slide coupling: The circumferential speed is about 30m/s, lubricated with No. 2 grease, the gap in the middle slide is filled with grease, and the grease change cycle is 1000 hours, suitable for ball bearing grease.The peripheral speed is about 30m/s. It is lubricated with N220 gear oil. The gap in the middle slide block is filled with oil. The oil change interval is 1000 hours. Sometimes a felt pad filled with oil is used.
