Description

CARRIER OF LINEAR MOTION GUIDE
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a carrier of a linear motion guide which is
generally adapted to various automated systems for guiding a linear movement, and
in particular to a carrier of a linear motion guide which includes a nut insertion
groove in an upper portion of a carrier for receiving a nut therein for thereby
implementing a rotation of the same and preventing a horizontal movement of the
same, obtaining a stable support state of a nut by increasing a contact area of a nut
which contacts with a carrier by eccentrically engaging an engaging bolt of a
variable track roller bearing installed in a lower surface of a carrier in the center of
the nut thereby preventing a movement of the engaging bolt, increasing a load
capacity of a carrier, preventing an abrasion, preventing a movement of the variable
track roller, obtaining an accurate operation of the system, having a free loosening
prevention structure of a nut and increasing the size of a wrench hole by forming a
position adjusting wrench hole in a head portion of the engaging bolt, for thereby
increasing a tightening torque based on a larger rotational force and enhancing a
durability and the life span of the system.
2. Description of the Background Art
As shown in Figure 5, in the structure of a carrier which was filed to the Korean intellectual Property Office(KIPO) by the same inventor as the present
application, a plurality of fixing track roller bearings(not shown) and a plurality of
variable track roller bearings 75 are installed in a lower portion of a carrier block 76
using an engaging bolt 74 which is fixedly installed based on a frame 70 having a
channel-shaped cross section and a rail member 72 and a nut 73 which are
longitudinally installed in a lateral wall 71 of the frame 70 and contact with the rail
member 72. The above-described conventional structure has the following problems.
First, since the diameters of a threaded portion and a head portion of an
engaging bolt 74 are different, and the centers of the same are eccentrically formed,
a fabrication process is complicated, and it is impossible to implement a certain
fabrication accuracy, so that a fabrication cost is increased, and an operation error is
increased for thereby decreasing a reliability of a product.
Second, since the fabrication process is complicated, and an arc with respect
to an adjusting angle is short when adjusting an eccentricity, it is difficult to
implement an accurate eccentricity adjustment, so that a long assembling time is
needed.
Third, since the contact surface of the nut 73 which contacts with the carrier
block 76 is limited to a lower surface, and the contact portion of the engaging bolt 74
is limited to an inner surface of an installation hole of the carrier block 76, the entire
contact surface is decreased, so that it is impossible to implement a state support
state of the engaging bolt. In- the case that a load or impact is applied to the carrier
block in the horizontal direction, the carrier block 76 is pushed, so that the inner portion of the installation hole of the carrier block which is formed of a relatively soft
material and contacts with the engaging bolt 74 is worn out, so that the nut 73 and
the engaging bolt 74 are moved min the horizontal direction, whereby the variable
track roller bearing 75 is escaped from the rail member 72. In this case, it is
impossible to obtain an accurate linear movement. In addition, if a larger load is
applied to the system, it is impossible to implement an accurate operation.
Fourth, in the conventional art, since there is not a free loosening prevention
structure of the nut 73, the nut 73 is loosened based on the repeated operation of
the carrier block 76, and the engaged state of the engaging bolt 74 becomes a
unstable state, so that it is impossible to implement a stable contact of the variable
track roller bearing 75 with respect to the rail member 72 for thereby causing an
error operation.
Fifth, since the position adjusting wrench hole 77 is formed in an end portion
of the threaded portion of the engaging bolt 74, the size of the formation of the
position adjusting wrench hole 11 is increased, so that the wrench hole 11 is
decreased. Therefore, a rotational force is intensively applied to a small area portion,
so that the wrench hole 77 or a circumferential portion of the wrench are easily work
out. In addition, since the rotational force for rotating the engaging bolt 74 is small, it
is impossible to implement a stable adjusting operation for the position setting.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a carrier of a linear motion guide which overcomes the problems encountered in the conventional
art.
It is another object of the present invention to provide a carrier of a linear
motion guide which is capable of preventing an abrasion by implementing a stable
and tight support state of a nut by increasing a contact area of a nut which contacts
with a carrier and preventing a movement of an engaging bolt, obtaining an
accuracy operation for preventing a free position change of a variable track roller,
decreasing an assembling time by implementing an easier and accurate position
setting of the variable track roller bearing, increasing the size of a wrench hole,
applying a larger rotational force and increasing a support capacity of a load and a
durability and life span of the system.
To achieve the above objects, there is provided a carrier of a linear motion
guide which includes a circular nut insertion and support groove which is formed in
an upper potion of the carrier block, a circular nut which is inserted in such a manner
that the lower and outer surfaces of the nut are tightly contacted with the inner
surfaces of the nut insertion and support groove, and the nut is not moved in the
horizontal direction and has an eccentric engaging hole which is eccentric from the
center point, a rotation guide hole formed in a bottom center portion of the nut
insertion and support groove of the carrier block, a screw loosening prevention
structure formed of a screw hole which passes through the nut and a set screw
engaged into the screw hole, and an engaging bolt which is engaged to the
eccentric engaging hole and has the same diameters except for a head portion thereof in a linear shape with no eccentricity and a wrench hole formed in the head
portion in a structure in which a channel shaped frame and a rail member which are
longitudinally formed in both lateral walls of the frame are formed, and a plurality of
fixing and variable track roller bearings are inserted in a lower portion of a carrier
block and contact with the rail member.
To achieve the above objects, there is provided a carrier of a linear motion
guide in which a nit insertion and support groove is formed in an upper portion of the
carrier for thereby supporting a lower and outer surface of the nut and implementing
a rotation of the same and preventing a position change in a horizontal direction. In
addition, an engaging bolt of the variable track roller bearing installed in the lower
surface of the carrier is eccentrically engaged with respect to the center of the nut.
To achieve the above objects, there is provided a carrier of a linear motion
guide in which it is possible to prevent a free loosening operation of the nut by an
external impact or movement which is tightened by a screw hole which passes
through a certain portion of the nut and a set screw.
To achieve the above objects, there is provided a carrier of a linear motion
guide in which a position adjusting wrench hole is formed in a head portion of the
engaging bolt, not in the threaded portion of the engaging bolt, for thereby forming a
wrench hole having a relatively larger diameter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The embodiments of the present invention will be described with reference to
the accompanying drawings.
Figure 2 is a view illustrating an embodiment of a carrier of a linear motion
guide according to the present invention. As shown therein, in a structure in which a
channel shaped frame 1 and a rail member 3 which are longitudinally formed in both
lateral walls 2 of the frame are formed, and a plurality of fixing and variable track
roller bearings 5' and 5 are inserted in a lower portion of a carrier block 4 and
contact with the rail member 3, a carrier of a linear motion guide includes a circular nut insertion and support groove 10 which is formed in an upper potion of the carrier
block 4, a circular nut 20 which is inserted in such a manner that the lower and outer
surfaces of the nut 20 are tightly contacted with the inner surfaces of the nut
insertion and support groove 10, and the nut 20 is not moved in the horizontal
direction and has an eccentric engaging hole 22 which is eccentric from the center
point 21, a rotation guide hole 30 formed in a bottom center portion of the nut
insertion and support groove 10 of the carrier block 4, a screw loosening prevention
structure 40 formed of a screw hole 41 which passes through the nut 20 and a set
screw 42 engaged into the screw hole 41, and an engaging bolt 50 which is
engaged to the eccentric engaging hole 22 and has the same diameters except for a
head portion thereof in a linear shape with no eccentricity and a wrench hole formed
in the head portion 51.
In addition, the fixing track roller bearing 5' is engaged using the engaging
bolt 50.
In the drawings, reference numeral 60 represents a tool insertion and support
hole which used for tightening or loosening a nut.
The operation of the carrier for a linear motion guide according to the present
invention will be described.
The carrier block 4 of Figure 1 includes a pair of fixing track roller bearings 5'
which are linearly parallel from each other when seeing in a left direction in the
drawing and are not moved. The variable track roller bearing 5 which is positioned
eccentrically in the right direction and is position-adjusted by an operation of the nut 20 is installed between the fixing track roller bearings 5'.
In the present invention, the number of the fixing and variable track roller
bearings 5' and 5 is not limited. Preferably, four or more fixing and variable track
roller bearings 5' and 5 may be adapted.
In the above construction, as shown in Figure 2, in a state that the variable
track roller bearing 5 is moved in maximum in the direction of the center of the
carrier block 4, and the widths of the fixing and variable track roller bearings 5' and 5
are smaller than the widths of the distanced rail members 3 in order to engage the
frame to the rail member 3, the frame 1 is pushed. Therefore, the fixing and variable
track roller bearings 5' and 5 do not tightly contact with the rail member 3 as
indicated by the full line of Figure 3. Namely, the fixing and variable track roller
bearings 5' and 5 are simply placed thereon.
In the above state, the fixing and variable track roller bearings 5' and 5 are
tightly contacted with the rail member 3 by a certain contact pressure and slide
smoothly without a certain movement. A tool(not shown) is inserted into a screw
hole 41 from which a tool insertion and support hole 6 and a set screw 42 are not
removed, and then the nut 20 is rotated in a certain direction. Therefore, as shown
in Figure 3, the engaging bolt' 50 engaged to the eccentric engaging hole 22 which is
eccentric with respect to the center point 21 of the nut 20 and the variable track
roller bearing 5 which is engaged thereto are moved as indicated by the imaginary
line and contacts with the rail member 3 for the reason that the rotation center of the
nut 20 is not changed as the nut 20 is tightly inserted into the nut insertion and support groove 10, and the engaging bolt 50 is eccentrically fixed with respect to the
center of the nut 20. Therefore, the center of the engaging bolt 50 is changed when
the engaging bolt 50 is rotated.
In a state that the variable track roller 5 is contacted with the rail member 3,
when the nut 20 is more rotated, the variable width of the variable track roller
bearing 5 is increased, and the distance between the fixing and variable track roller
bearings 5' and 5 is increased, and it is contacted with the rail member 3 of the other
side up to the fixing track roller bearing 5'.
In a state that the fixing and variable track roller bearings 5' and 5 are
contacted with the rail member 3 by a certain pressure, the set screw 42 is tightened
in the screw hole 41 , and an end portion of the set screw 42 strongly pushes the
bottom of the nut insertion and support groove 10 for thereby preventing the nut 20
from being freely rotated. Therefore, it is possible to prevent a variation of the
contact pressure of the fixing and variable track roller bearings 5' and 5.
In the case that the fixing and variable track roller bearings 5' and 5 are
removed from the carrier block 4, a hexagonal head wrench is inserted into the
wrench hole 52 formed in the head portion 51 of the engaging bolt 50 and is rotated
therein for thereby easily loosening the nut 20.
Figure 4 is a view illustrating the construction of the carrier according to
another embodiment of the present invention. In Figures 1 through 3, the variable
track roller bearing of the carrier is contacted with the inner surface of the frame and
is moved. In Figure 4, the variable track roller bearing of the carrier is contacted with an inner surface of the frame, and is moved. The present invention may be adapted
to either of the above-described two operation types or may be commonly adapted
to both the above-described operation types.
As described above, in the present invention, the contact area of the nut
which contacts with the carrier is increased, and a support state of the nut is very
stable for thereby preventing a movement of the engaging bolt. In addition, it is
possible to prevent an abrasion of the carrier, and the free position change of the
variable track roller is prevented for thereby enhancing a weight support capacity of
the carrier. It is possible to implement an accurate operation. The position setting of
the variable track roller bearing is easily, stably and accurately obtained.
In addition, the size of the hole may be increased by forming a wrench hole in
the head portion of the engaging bolt. A larger rotational force may be obtained. A
durability and a life span may be increased.
As the present invention may be embodied in several forms without departing
from the spirit or essential characteristics thereof, it should also be understood
that the above-described embodiments are not limited by any of the details of the
foregoing description, unless otherwise specified, but rather should be construed
broadly within its spirit and scope as defined in the appended claims, and
therefore all changes and modifications that fall within the meets and bounds of
the claims, or equivalences of such meets and bounds are therefore intended to
be embraced by the appended claims.
