Figure 4 The Basic Ratio

To obtain the basic ratios of a group of bearings, divide the lubricant

requirements of each bearing by the smallest oil requirements of the

group. (Refer to calculating lube requirements, Trabon Application

Engineering Lit. No. L20115.)

Example:

This illustration shows both the relative and actual quantity of oil

discharged during one complete cycle of the divider valve.

It can be seen in Figure 5 that the total oil discharged by the divider

valve during one cycle is .080 cubic inches. Conversely, if .080

cubic inches of oil is supplied to the inlet of this divider valve it will

complete one cycle.

(One cycle equals Ts x 2)

(Where Ts = total of intermediate section sizes)

Figure 5 Proportioning

Examples:

By multiplying the basic ration by the smallest intermediate section

capacity (5) the actual section size can be determined.

Crossporting joins two adjacent intermediate sections, thus

combining their capacities.

Example: 15 S & 15 S yields .060 cu.in./cycle

10 S & 10 S yields .040 cu.in./cycle

A wide range of ratios are available.

SYSTEM DESIGN

Proportioning—

The proportioning of oil in a Maxi-Flo system depends on the

relative size of the pistons in a divider valve. Therefore, to size the

pistons correctly one need only know the relative size of the oil

requirements. This relative size is called "The Basic Ratio."
