| Silent chain drive for power transmission |
Ramsey has manufactured silent chain for more than 80
years.
Silent chain drives are capable of transmitting power with low noise, high
efficiency, and reduced vibration, at speeds and loads that exceed the
capability of other belts and chains. There are many styles of silent chain
and Ramsey offers a wide range of designs for different application
requirements and budgets. Almost all Ramsey silent power transmission chains
utilize efficient, quiet, two-pin roller bearing joints; technology which
has been shown to outperform conventional, round pin joints.* These chains
can be found in a wide variety of demanding industrial applications and
similar designs are used in 4 wheel drive automobiles and NASCAR racing
engines. | |
|
| Typical conveying chains |
Ramsey silent chain is the preferred conveying
solution for the worlds largest glassware producers.
Silent conveying chains provide a heat resistant, flat, durable, non-slip,
conveying surface that can be customized to fit a wide range of industrial
applications. All Ramsey conveying chains are designed to smoothly and
efficiently engage sprockets, providing minimal speed variation in the
conveying surface. Chain options include single pin or two pin joint
construction, link-spacer or all link constructions, stainless steel, pin
head protection, and widths up to 20 inches (508mm). | |

| Silent Chain Sprockets |
Stock and Made to Order
Ramsey offers a full range of stock and made to order sprockets in pitches
ranging from 3/16” pitch to 2 1/4” pitch. Stock sprockets are available with
minimum plain bores or taper lock bushings. For an additional charge they
can be machined with a finished bore and keyway. Made to order sprockets
provide an almost unlimited range of options and are a large part of our
daily production.
Ramsey also supplies sprockets to replace most competitors' products. We
welcome all inquiries.
Materials
RPV, RP and SC sprockets are typically made from carbon steel or ductile
iron, with sprocket teeth hardened to Rockwell hardness of Rc 50. For RP and
SC only, some sprocket sizes are available in class 30 gray iron with
unhardened teeth. Other materials are available subject to customer
preference, sprocket size, cost, and availability. | |
|
| Flexible Shaft Couplings |
There are two models of Ramsey couplings, the Straight
Type and the Diagonal Type. Straight Type couplings are composed of coupling
halves that are split perpendicular to the shaft axis. A hardened steel
silent chain joins the two halves. Diagonal Type couplings are split at an
angle to the shaft axis. Due to the angular split, the chain that wraps a
Diagonal couplings is loaded in shear,as well as tension. This results in
Diagonal couplings having a somewhat higher load capacity than straight
couplings, where the chain is only loaded in shear.
Both Straight and Diagonal chain couplings have a torque capacity that is
greater than the largest diameter mild steel shaft on which it is mounted.
The choice between the the two types is often determined by ease of
installation in a specific application. | |

 |
| Roller Chain Sprockets, Pulleys, and Gears |
| Ramsey offers made to order roller chain sprockets,
gears, and pulleys. There is no minimum order quantity and parts can be
machined from the material of your choice, to your exact specifications.
Tooth hardening is available. | |

| Complete Chain Drive Solutions |
Are you faced with coupling together multiple
components to achieve the speeds and drive ratios you require? Do you find
it difficult to find an off the shelf speed reducer that will accommodate
your center distance? Or, are you tasked with designing an enclosure and
lubrication system for a chain drive?
A Ramsey Hyperlink drive may be the answer to your problems.
Ramsey’s Hyperlink drives are customized, fully enclosed chain drive
solutions built to deliver the exact loads, speeds and drive ratios needed
in your application. . All Hyperlink drives feature proprietary, high
performance RPV, or Rampower , silent chains. Chains are sized for each
application and matching sprockets are precision machined and heat treated
for maximum wear life. Input and out put shafts can be machined with keyways
or splines and enclosures can be designed to fit specific space and mounting
requirements. Fully contained lubrication systems are available and all
components are sized to provide long lasting, trouble free, performance. | |

Take Out Arm Drives
Working with Glass Industry engineers, Ramsey has developed a new solution
that greatly extends the life of take out arm drives. Utilizing high
performance RPV silent chain in place of elastomeric belts, Ramsey take out
arm drives can provide more than 10 times the life of a typical belt drive.
Available in kit form to retrofit most existing take out arms or as a
complete assembly.
