Oldham clamp coupling consists of two parts: hubs and elastomer.The oldham coupling respectively connects to the driving shaft and driven shaft. It is alco called shaft couplings. Most of the general power machines are connected to the working machine by means of a shaft coupling. Oldham couplings work in high speed and heavy load transmission. Oldham couplings also have the function of buffer, vibration reduction and improving the shafting dynamic performance.
