Pulley Wheels With Bearings

pulley wheels with bearings

  • A person's way of standing or moving

  • Relation or relevance

  • (bearing) relevant relation or interconnection; "those issues have no bearing on our situation"

  • (bearing) the direction or path along which something moves or along which it lies

  • The way one behaves or conducts oneself

  • bearing(a): (of a structural member) withstanding a weight or strain

  • a simple machine consisting of a wheel with a groove in which a rope can run to change the direction or point of application of a force applied to the rope

  • @#!* is the third full-length album by the punk rock band Pulley.

  • A wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights

  • A pulley, also called a sheave or a drum, is a mechanism composed of a wheel on an axle or shaft that may have a groove between two flanges around its circumference. A rope, cable, belt, or chain usually runs over the wheel and inside the groove, if present.

  • (on a bicycle) A wheel with a toothed rim around which the chain passes

  • A wheel or drum fixed on a shaft and turned by a belt, used esp. to increase speed or power

  • A circular object that revolves on an axle and forms part of a machine

  • (wheel) change directions as if revolving on a pivot; "They wheeled their horses around and left"

  • Used in reference to the cycle of a specified condition or set of events

  • A circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move easily over the ground

  • (wheel) a simple machine consisting of a circular frame with spokes (or a solid disc) that can rotate on a shaft or axle (as in vehicles or other machines)

  • steering wheel: a handwheel that is used for steering

Factory Ruins - Orange Trail Wilderness Area, The Great Swamp National Wildlife Refuge,
Meyersville, New Jersey

The Great Swamp was a thriving community many years ago appropriately known as Meyersville. There were numerous homes there as well as some factories and businesses, and here is evidence of one of the factories. It took me a few minutes to figure this out, as I was pretty sure that no one shot this metal wheel into a tree. My theory is that the shaft was at one time supported by wooden mounts with bearings mounted periodically along the drive shaft. The wheel was a drive wheel that was likely connected via a leather pulley to a steam engine (there's no water differential in the swamp to drive anything by water power). But how did the wheel get imbedded in the tree? A close look at the tree showed that after the plant was abandoned the structure rotted away and a small tree grew next to the wheel. Then as the tree grew larger the trunk pressed against the wheel and the tree eventually grew around the wheel. Then after the wheel was imbedded in the tree the wooden supports for the shaft rotted away and left a 20 foot shaft pointing directly out of the side of the tree. The shaft is solid steel and quite heavy, so the bend in the shaft is due to the weight of the shaft.

Hay Loader Drum and Motor

Hay Loader Drum and Motor

The core of the hoist is a differential from an old Chevy. Others have been tried, but don't work as well. You can see the bulge of the differential in the center between the brake at the far left and the winding drum. The pulley connects to the input shaft of the differential. Per Eric, the bearings and seals have been replaced a time or two over the years.
Also seen is the alternator and, obviously, the gasoline engine. Fire that puppy up and get to work!

To operate, one fellow controls the brake shoe at the output axle at the far side of the differential. Normally the winding drum is idle, under tension from the rope, and the brake drum is free-wheeling, as allowed by the differential. But when the brake shoe is applied, the axle fitted with the brake drum slows, and the differential action causes the winding drum to take up the rope. This lifts the bale of hay, at a rate of speed and strength that is controlled by the amount of slip allowed on the brake-drum axle. To let down the line after a bale is stacked in place on the hay stack, the brake is loosed fully, allowing the that drum to freewheel at will and allowing the winding drum to do whatever it wants to, which in this case is to reverse under tension and pay out the line ready to start over.
