Proper V-belt drive design and installation are important to the performance and lifespan of a blower and blower package. Every blower has a factory specified overhung load limitation that needs to be met when a v-belt drive is designed for a blower package. Incorrectly designed v-belt drives lead to premature bearing failure and shaft breakage as shown in Figure 1 and 2.
Even if a drive is correctly designed, it can lead to blower failure if incorrectly installed. Below we have an incorrectly installed v-belt sheave (figure 3) next to a correctly installed v-belt sheave (figure 4). The closer you can get the sheave to the face of the blower (as in figure 4), the better!
