A safety device that stops the escalator if the speed exceeds the rated speed, or before the Steps' traveling direction changes due to an abnormality such as breakage of the Drive Chain. *A standard device for public-use escalators or those exceeding 6m in rise.
Increase the life of chains and belts with chain and belt tensioners from Grainger. They can extend belt and chain life by as much as 30%. Tensioners minimize wear on shaft and drive bearings and include elastomeric components to provide shock and vibration absorption.
Chain Tensioner Drive Chain Accessories Excessive chain sag can cause vibration and excessive noise and prevent the chain from properly engaging the sprocket, which prevents the chain from operating smoothly.
Drive chain is a machine element that transmits the power of a motor or the like as tension to driven machinery via sprockets. Features include: large reduction ratio, high flexibility in the distance between shafts, both sides can be used for multi-axis shaft transmission, etc.

Mechanisms and Mechanical Devices Sourcebook, Fifth Edition, contains new chapters on mechanisms for converting renewable energy into electrical power, 3D digital prototyping and simulation, and progress in MEMS and nanotechnology based on carbon nanotubes.
Chain drive was the main feature which differentiated the safety bicycle introduced in 1885, with its two equal-sized wheels, from the direct-drive penny-farthing or "high wheeler" type of bicycle. The popularity of the chain-driven safety bicycle brought about the demise of the penny-farthing, and is still a basic feature of bicycle design today.
Chain drive, Device widely used for the transmission of power where shafts are separated at distances greater than that for which gears are practical. In such cases, sprockets (wheels with teeth shaped to mesh with a chain) take the place of gears and drive one another by means of a…
Chain Drive Principles. Chain drives normally transmit power from one rotating shaft to another. Chain drives maintain a positive speed ratio between driver and driven sprockets. The driver and driven sprockets will rotate in the same direction on typical chain drives.

…assembled from pin links and roller links. A pin link consists of the two side plates connected by two tightly fitted pins. A roller link consists of two side plates connected by two tightly fitted bushings on which hardened steel rollers are free to rotate.
Automatic Traction Devices (A.T.D.'s) are used primarily on commercial vehicles, emergency vehicles, and busses. ATD's are devices mounted under the vehicle that sling chain segments under the inside drive wheels. These devices can be deployed by the driver when the need for extra traction is required.
While servicing a chain-and-sprocket drive assembly on a roof tile conveyor system, an employee turned off the conveyor, removed the guard, and began work on the drive assembly without locking out the system. When someone started the conveyor, the employee's fingers became caught in the chain-andsprocket drive and were amputated.

Chain Drive Counterbalancers can change as the chain wears. They usually have a way to take up or adjust slack on the chain as it wears. Some Yamaha and Honda twins use adjustable, chain driven, Balancers. Usually, one of the sprockets can move, tightening or loosening the chain. Sometimes the adjuster sprocket is spring loaded.
