WebVariable speed fluid couplings with incorporated gears are the workhorses for higher horsepowers and/or speeds, and combine variable couplings with sleeve bearings one or two steps of gear sets, all included in one housing (Figure 8). It was basically developed for boiler feedwater pump applications, but has also been successfully used for WebSep 22, 2024 · Use special coupling indicator clamps where possible. Ensure that thermal growth allowance is correct. Using an indicator clamped on the coupling, depress and lift on each coupling and note the dial indicator change. Determine if the deflection is normal for this machine. Refer to OEM manual.
