Regal Rexnord Corporation is a manufacturer of electric motors and power transmission components based in Milwaukee, Wisconsin. The company has manufacturing, sales, and service facilities throughout the United States, Canada , Mexico , Europe and Asia , with about 29,000 employees.
Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft.It is defined as the force (usually in tonnes-force or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient ...
Rexnord was founded as the Chain Belt Company by inventor Christopher W. Levalley at the age of 58. Levalley, along with Chain Belt co-founders F.W. Sivyer and W.A. Draves, held the first board of directors meeting on September 9, 1891. Chain Belt was incorporated in the state of Wisconsin on February 24, 1892. [citation needed]
A typical chain tool. With a chain placed on the central sprocket, the screw is turned until a pin is pushed from the linkage. A chain tool is a small mechanical device used to "break" a bicycle chain in such a way that it can be mended with the same tool. A bicycle chain has links and plates that are pinned together; these pins can be pushed ...
The mechanical advantage would equal the ratio of chain link pairs required for each revolution to the net gain of chain link pairs. Put another way, the mechanical advantage would be the distance of pull required for each unit distance of gain. The mechanical advantage at the differential sprocket pair equals P 1 / P 1 − P 2 .
By 1913 annual sales reached $1 million. At that time the company's products were organized into three major divisions: chain products for power transmission; chain-driven construction machinery; and chain-powered bulk conveying equipment. In 1914 it introduced the Rex brand-name, which was first used on a chain-driven concrete mixer.
Drawbar force gauges allow early detection of problems with the spindle's Belleville spring stack, verification of performance of the clamping system as a whole, help prevent damage to spindle taper and other machine features critical to machining accuracy, and ultimately help to keep the machine operator safe.
