Session 6 Shafts and bearings

TOTAL TIME: 1 to 2 Hours

OBJECTIVES: To begin learning about how power is transmitted by shaft and bearing mechanisms.

To work with the models of shaft and bearing systems.

MATERIALS: Model materials & supplies, wood, wire, glue, pins, construction paper, etc.

Shaft and bearing materials or examples (rear auto axle or similar parts).

PROCEDURES:

Step 1: 10 minutes

Discuss the different materials used for bearings and pass around examples of bearings.

Step 2: 10 minutes

Discuss the type of bearings to be used in the mill being built during the training program.

Trainer Note

Oil soaked or greased wood bearings make excellent low-cost bearings. If they are to be used, discuss their maintenance needs and their limitations.

Step 3: 40 minutes

Construct and work with models, making various shaft and bearing combinations.

Trainer Note

For groups with very little experience with machinery and power, a model making kit consisting of 1 Erector Set, 1 Tinkertoy and 1 Lincoln Log, plus an assortment of small screws and bolts can be used. Encourage the use of models at all stages of the building process.
