Lubrication maintenance of coupling

   Single-head gear coupling: High circumferential speed of about 60m/s, lubricated with grease of No. 0 or No. 1, the amount is to fill the coupling, the grease change cycle is 6-12 months, and the adhesion of the lubricant is required.

Good, the sealing requirements are not strict; the high 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, and the oil change interval

12 months, ordinary mineral oil, not strict requirements for sealing; high circumferential speed of about 30m/s, lubricated with 0 or 1 grease, the amount is to fill the coupling, the grease change cycle is 6 months, and lubrication is required

The adhesion of the lubricant is better, and the sealing requirements are not strict.
　 Jaw-type coupling: High peripheral speed of about 150m/s, lubricated with N150, N220 gear oil, and sufficient flow is required to pass through the coupling continuously in the axial direction without sealing.
　 Diaphragm coupling: High peripheral speed of 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: high peripheral speed of 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; high peripheral speed

Approximately 150m/s, lubricated with N150, N220 gear oil, and sufficient flow is required to continuously pass through the coupling in the axial direction. 　

    Cross slide coupling: High circumferential speed of 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 high circumferential speed is about 30m/s, and it is lubricated with N220 gear oil. The gap in the middle sliding block is filled with oil. The oil change interval is 1000 hours, and sometimes a felt pad filled with oil is used.
