SILENT OR INVERTED TOOTH CHAIN

Silent or inverted tooth chain consists of a series of toothed links alternately assembled either with pins or with a combination of joint components in such a way that the joints articulate between adjoining pitches. Side Guide chain has guide links which straddle the sprocket sides to control the chain laterally. Center Guide chain has guide links that run within a circumferential groove or grooves for lateral control.

Characteristics of Silent Chain Drives

The silent or "inverted-tooth" driving chain has the following characteristics: The chain passes over the face of the wheel like a belt and the wheel teeth do not project through it; the chain engages the wheel by means of teeth extending across the full width of the under side, with the exception of those chains having a central guide link; the chain teeth and wheel teeth are of such a shape that as the chain pitch increases through wear at the joints, the chain shifts outward upon the teeth, thus engaging the wheel on a pitch circle of increasing diameter; the result of this action is that the pitch of the wheel teeth increases at the same rate as the chain pitch. The accompanying illustration shows an unworn chain to the left, and a worn chain to the right, which has moved outward as the result of wear. Another distinguishing feature of the silent chain is that the power is transmitted by and to all the teeth in the arc of contact,...

Products & Services
Silent Chain
Silent chain or inverted-tooth chain features teeth on its links that engage the sprocket teeth.  Silent chain can be wide and is used in a variety of power transmission and conveying applications.
ANSI Roller Chain Sprockets
Roller chain sprockets engage chain drives in power transmission and conveyor systems, though sprockets can engage any perforated material. Chain drives can be highly efficient and can produce a mechanical advantage as speed reducers/increasers. Sprockets conforming to ANSI standard B 29.1 are not meant to engage roller chains of any other parameter. ANSI conforming roller chain is smaller and somewhat weaker than its European counterpart.
ISO Roller Chain Sprockets

Roller chain sprockets engage chain drives in power transmission and conveyor systems, though sprockets can engage any perforated material. Chain drives can produce a mechanical advantage as speed reducers/increasers. ISO sprockets are designed to engage British Standard Chain and conform to ISO standard R606. These sprockets are not interchangable with ANSI defined sprockets.

Conveyor Chain
Conveyor chain is used for material conveyance under harsh conditions, in specialty applications, or when material can be allowed to fall through gaps in the conveying surface.
Rack and Pinion Gears
Rack and pinion gears are used to convert rotation into linear motion.
