Double-headed toothed coupling: The maximum peripheral speed is about 60m/s, lubricated with No. 0 or No. 1 grease, the amount used is to fill the coupling, the grease-removal period is 6-12 months, and the lubricant adhesion is better. Lax sealing requirements; the maximum circumferential speed of about 60m / s, with N150, N220 gear oil lubrication, the amount used to install half the capacity of the coupling, so that no oil leakage at rest, change the oil cycle 12 months, the sealing requirements Lax; the highest circumferential speed of about 150m / s, with N150, N220 gear oil lubrication, requires sufficient flow, continuous through the shaft along the axial direction, no seal.
Single-head gear coupling: The maximum peripheral speed is about 60m/s, lubricated with No. 0 or No. 1 grease, the amount used is to fill the coupling, the grease-removal cycle is 6-12 months, and the lubricant adhesion is better. Strict requirements for sealing; the maximum circumferential speed of about 60m / s, with N150, N220 gear oil lubrication, the amount used to install the coupling capacity of half, so that no oil leakage at rest, the oil change period of 12 months, ordinary mineral oil , Lax sealing requirements; the highest circumferential speed of about 30m / s, with No. 0 or No. 1 grease lubrication, the amount used to fill the coupling, grease cycle 6 months, requiring better lubricant adhesion, sealing requirements Lax.
In-line coupling: The maximum peripheral speed is about 150m/s. It is lubricated with N150 and N220 gear oils. It requires sufficient flow and continuously passes through the coupling along the axial direction without sealing.
Spring Couplings: The maximum peripheral speed is about 30m/s, lubricated with No. 1 grease, and the amount is filled with couplings. The grease-removal period is 1000 hours and the sealing requirements are not strict.
Disc spring coupling: The maximum peripheral speed is about 60m/s. It is lubricated with No. 2 or No. 3 grease. The amount used is to fill the coupling and the grease replacement cycle is 12 months. The sealing requirements are not strict; the maximum peripheral speed is approx. 150m/s, lubricated with N150, N220 gear oil, requires sufficient flow and passes axially through the coupling.
Cross-slider type coupling: The maximum peripheral speed is about 30m/s. It is lubricated with No. 2 grease. The gap in the middle slider is filled with grease, and the grease replacement cycle is 1000 hours. It is suitable for ball bearing grease. The maximum peripheral speed is about 30m/s. It is lubricated with N220 gear oil. The gap in the middle slider is filled with oil. The oil change interval is 1000 hours. Sometimes the felt pad of M oil is used.
How to maintain and lubricate the coupling
How to maintain and lubricate the coupling is as follows:
