Clubmaking 101

For increased speed, some clubmakers will dip a small portion of the shaft tip in the epoxy and then insert the shaft into the hosel. In either case, insert the epoxy coated shaft slowly into the hosel with a rotating motion while going in an up and down motion to ensure complete coverage around the total circumferences of the two components.

Control line

Control line (also called U-Control) is a simple and light way of controlling a flying model aircraft. The aircraft is connected to the operator by a pair of lines, attached to a handle, that work the elevator of the model. This allows the model to be controlled in the pitch axis. It is constrained to fly on the surface of a hemisphere by the

Lubrication Selection for Enclosed Gear Drives

2020/8/15RO inhibited oils are commonly used to lubricate high-speed single helical, herringbone reduction gear sets that have pitchline velocities greater than 3,500 feet/minute (17.5 meters/second) and are subjected to light to moderate loads.

OAV Air Bearings

We design our Air bearings to have a special epoxy to block the pores on the surface where air flow is not desired. Our design forces the flow in the direction of the frictionless surface. This results in higher stiffness, more stability, and better damping properties.

Carbon/Graphite for Dry Running Mechanical Seal

2020/4/22In high-speed applications, this helps to facilitate heat dissipation away from the sealing interface where frictional heat is typically generated. Coupled with graphite's low coefficient of friction, its high-thermal conductivity considerably reduces excessive heat buildup at the sealing interface, which can ultimately deteriorate the seal face, coke hydrocarbons and introduce leak paths.

Optimal Design of High Speed Rotating Graphite/Epoxy

1983/3/1An important problem in the design of a high speed rotating shaft of significant span is the lateral stability. With light weight Graphite/Epoxy material it is relatively easy to meet the torsional stiffness and strength requirements using a thin walled tube, but this might lead to a shaft which is sensitive to lateral buckling.

Advances in the design and manufacture allow today to increase both the performance and efficiency of the machines by making them operate in speed ranges increasingly high. However, the forces generated, increasingly important, strongly urge the overall dynamic behavior of the machine and the vibration amplitudes often become too high for the structure can withstand.

Richard Nakka's Experimental Rocketry Site

A metallic item of mass rotating at high speed represents a significant amount of stored energy. A chuck, on its own, is heavy, and when holding a workpiece, even more so. Jamming, dismounting of the workpiece, or other such adversity may subject the operator to the unleashing of this energy, often manifested in a sinister way.
