Press, Shrink, and Friction Joints

  Definitions. A press joint, also called a force joint, is obtained by forcing a shaft into a hole that is slightly smaller than the shaft. This is possible because of the elasticity of the materials which produces the grip that holds the hub and shaft together.

A shrink joint differs from a press joint chiefly by the method of assembling it. The hub is heated to expand its bore and to slip it on the shaft. When the hub cools down to the temperature of the shaft, the grip is produced in the same way as in the force joint. The shrink joint is also used to connect machine parts by means of special rings, anchors, and tie rods.

  In a friction joint the holding grip is produced by the conical shape of the shaft end and the hub bore and by the pull of a nut, or by a slotted hub whose bore is smaller than the shaft and which is spread by a wedge when the joint is being assembled.

Riveted Joints.

General Remarks.- Riveting has been the standard method of joining plates and structural parts before welding began to replace it with increasing rapidity.

Rivets.-A rivet is a round bar consisting of an upset end called the head, and a long part called the shrank. The rivet blank is heated to a red glow, inserted into one of the holes, and, while the head is held firmly against the plate by a heavy sledge, the projecting end is formed into a second head, called the point, by means of a hand hammer and set or by a press.

Button heads are used for small rivets which are driven cold; pan heads are used chiefly in ship work; countersunk heads are used only in special cases, chiefly in structural work and below the water line in ships; the countersunk points weaken the plate so much that they should be used only when unavoidable; the others, including button heads, are used in boiler and structural work.

Bearings

A Beaming is a machine part which supports a moving part and confines its motion. That part of a shaft which rotates in a bearing is called a journal. Bearings in which one rubbing surface slides over another are called plain bearings and may be divided into two classes: Those with a continuous rotary motion and those with an intermittent motion. To the first class belong journal bearings, which carry a load acting at right angels to the shaft axis, and thrust bearings, which take a load acting in the direction of the shaft axis. To the second class belong bearings of parts having a rocking motion, as crossheads.

Bearings with a continuous rotary motion form the great majority of all bearings. Bearing failures.-The failure or need of replacement of a bearing with sliding contact may be due to:

a) excessive wear of the bearing surfaces;

b) overheating; or

c) cracking of the bearing metal.

Excessive Wear.-Wear is caused by metal-to-metal contact. It cannot be entirely eliminated but can be reduced by providing a sufficient bearing area and by adequate lubrication

Overheating, if not stopped in time, may cause either seizure of the journal if it runs in a hard-metal bearing or melting of the bearing surface if the bearing is lined with a metal having a low-melting temperature. Overheating is primarily caused by metal- to-metal contact. Lubrication decreases the danger of overheating.

Cracking of the bearing metal is due to heavy shock loads, such as are taking place in the running gear of internal combustion engines when the compressive stresses in the bearing metal exceed its endurance limit..
