ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to an improved method and device for securing a cylindrical component in any mechanical assembly in any industry, and more particularly, to a method and device for securing a cylindrical component in a precision web fed media transport system employed in an imagesetter or platesetter in the prepress printing industry.
2. Description of the Prior Art
There are many uses for cylindrical components in mechanical assemblies in various industries. For example, cylindrical shafts are used to drive or transfer power throughout machines, cylindrical rollers are used to guide web substrates, and cylindrical bearings are used to facilitate rotation of various machine elements. Quick, secure and easy installation of cylindrical components is desirable to save both time and money.
Often, precision is required in fastening cylindrical components onto mechanical assemblies. One prior art precision system for fastening a cylindrical component
12
onto a mechanical assembly
8
is illustrated in FIG.
1
. Cylindrical component
12
is accurately positioned in a slot
19
with respect to first and second surfaces
14
and
16
, respectively. A machining slot
18
is sometimes used when machining the surfaces
14
and
16
with a milling machine. Typically a pair of precision slots
19
are used to secure either end of the cylindrical component
12
and to align the cylindrical surface
9
of the cylindrical component
12
with other components (not shown) of the machine assembly
8
.
The system
10
for securing the cylindrical component
12
includes a support
22
which is fastened onto the mechanical assembly
8
to secure the cylindrical component
12
between the support
22
and the surfaces
14
and
16
. The support
22
includes two clearance holes or slots
2
for accepting two screws
20
which, in turn, are secured into threaded holes
4
in the mechanical assembly
8
.
SUMMARY OF THE INVENTION
The present invention is directed towards a device and method for accurately securing cylindrical components onto mechanical assemblies in a manner which is easy, inexpensive and consumes little time. Both the removal and reinstallation of cylindrical components is simplified.
Specifically, a cylindrical component is secured in a slot of a mechanical assembly. The slot is defined by two registration surfaces which meet at a vertex and a third surface which meets one of the registration surfaces. The securing method includes: placing the cylindrical component into contact with the two registration surfaces; applying a force F
1
against the cylindrical component causing compression of the cylindrical component into the two registration surfaces; and applying an anti-rotational force against the third surface to prevent redirection of the force F
1
. One fastener which uses the above method includes: a surface which contacts the cylindrical component; a threaded engagement mechanism which secures the fastener to the mechanical assembly through a clearance hole in the fastener; and a protruded section which prevents rotation of the fastener by engagement with the third surface.
