  The present invention relates to a linear motion guide device used in a machine tool, an injection molding machine or the like, and a lubricant supply member of the linear motion guide device that supplies a lubricant to the outer surface of the guide rail, and a linear motion including the lubricant supply member. The present invention relates to a motion guide device.

Conventionally, for example, as a guide device for a member used in a machine tool, an injection molding machine or the like, a linear motion in which a guide rail and a slider straddling the guide rail are relatively moved via rolling of a plurality of rolling elements. There is a guide device (linear guide device).
The guide rail has rail-side rolling element rolling surfaces extending in the axial direction on both side surfaces.
The slider is provided with a slider main body straddling the guide rail so as to be relatively movable, and end caps joined to both end faces of the slider main body in the moving direction.

The slider body has a slider-side rolling element rolling surface facing the rail-side rolling element rolling surface, and a rolling element return path that passes through the slider body in the axial direction of the guide rail. A load rolling path is formed from the surface and the slider-side rolling element rolling surface. Further, the end cap is formed with a direction changing path that communicates the load rolling path and the rolling element return path.
In addition, each rolling element is slidably loaded into a rolling element rolling path formed by a load rolling path, a direction changing path, and a rolling element return path. Each rolling element rolls in the rolling element rolling path as the guide rail and the slider move relative to each other.

In such a linear motion guide device, a lubricant such as grease is supplied between each rolling element and the rail-side rolling element rolling surface in order to suppress deterioration in operability and durability. Generally, the lubrication state between the moving body and the rolling element rolling path is maintained. For this reason, the structure of a linear motion guide apparatus is made into the structure as described in patent document 1 and 2, for example.
The linear motion guide device described in Patent Document 1 forms a lubricant-containing member containing a lubricant in a shape corresponding to the outer shape of the end cap. The lubricant-containing member is sandwiched between a plate-like member interposed between the lubricant-containing member and the end cap, and a side seal formed in a shape corresponding to the outer shape of the end cap. Furthermore, the plate-shaped member, the lubricant-containing member, and the side seal are attached to the end cap using a bolt that penetrates the plate-shaped member, the lubricant-containing member, and the side seal.

  Moreover, the linear motion guide apparatus described in Patent Document 2 forms a side seal formed in a shape corresponding to the outer shape of the end cap into a shape corresponding to the outer shape of the end cap. Further, a lubricant-containing member that is formed into a shape corresponding to the outer shape of the end cap and contains a lubricant is inserted into the spacing member formed in a U-shaped cross section. Then, the spacing member and the side seal are attached to the end cap using the spacing member into which the lubricant-containing member is inserted and the bolt that penetrates the side seal.

In the case of the linear motion guide device described in Patent Documents 1 and 2, each rolling element and the rolling element on the rail side roll by supplying the lubricant that oozes out from the lubricant-containing member over time to the outer surface of the guide rail. It becomes possible to supply the lubricant between the surfaces. For this reason, it becomes possible to maintain the lubrication state of each rolling element and rolling element rolling path.
However, in the linear motion guide devices described in Patent Documents 1 and 2, when the lubricant-containing member is replaced, such as when the content of the lubricant is reduced, a bolt that penetrates the lubricant-containing member or the side seal is used. Must be removed. That is, when replacing the lubricant-containing member, it is necessary to remove the side seal or the like from the end cap, so that there is a problem that it takes time to replace the lubricant-containing member.

For this problem, for example, there is a linear motion guide device configured as described in Patent Document 3.
The linear motion guide device described in Patent Document 3 includes a lubricant containing member that includes a lubricant, and has a recess corresponding to the outer shape of the end cap. The containing member case is attached to the end cap. The lubricant-containing member case is provided with a pivot shaft that is rotatable about an axis extending in the vertical direction, and an attachment member that is rotatably supported by the pivot shaft.

The lubricant-containing member is accommodated in the concave portion of the lubricant-containing member case, and the side seal is contained by the mounting member in a state where the lubricant-containing member is sandwiched between the side seal and the lubricant-containing member case. Attach to the member case and attach the lubricant containing member to the end cap. In that case, the operation | work which takes out the old lubricant containing member accommodated in the recessed part and the operation | work which accommodates a new lubricant containing member in a recessed part are performed using an exclusive jig.
With the linear motion guide device described in Patent Document 3, the lubricant-containing member can be replaced without removing the lubricant-containing member case or the side seal from the end cap. For this reason, the replacement | exchange operation | work of a lubricant containing member becomes easy, and it becomes possible to shorten the work time required for the replacement | exchange operation | work of a lubricant containing member.

However, in the linear motion guide device described in Patent Document 3, the lubricant-containing member case has a complicated structure having a pivot shaft and a mounting member, and has a large number of parts. For this reason, the manufacturing cost of a lubricant containing member case increases, and the problem that the manufacturing cost of a linear motion guide apparatus increases arises.
Further, in the linear motion guide device described in Patent Document 3, when replacing the lubricant-containing member, the mounting member supported by the pivot shaft that is rotatable about the axis extending in the vertical direction is provided in the vertical direction. It is necessary to rotate around the extending axis. For this reason, a work space is required in the axial direction of the guide rail. Accordingly, when replacing the lubricant-containing member, it is necessary to move the slider in order to secure a work space, and thus there arises a problem that work conditions are limited depending on the structure of the linear motion guide device.

In addition, in the linear motion guide device described in Patent Document 3, it is necessary to use a dedicated jig and perform work in a narrow space formed between the upper surface of the slider and the guide rail when replacing the lubricant-containing member. is there. For this reason, depending on the structure of the linear motion guide device, there arises a problem that working conditions are limited.
Further, in the linear motion guide device described in Patent Document 3, since the side seal is pressed against the lubricant-containing member case by the mounting member and positioned, the side seal is compared with the structure that is mounted using bolts. The holding power of the seal is weak. For this reason, it is difficult to accurately position the side seal, and a gap may be generated between the side seal and the guide rail, which may cause a problem that the dustproof performance is deteriorated.
The present invention has been made paying attention to the above-mentioned problems, and does not require the work for the lubricant-containing member case or the side seal, and replaces the lubricant-containing member only by the work for the lubricant-containing member. It is an object of the present invention to provide a linear motion guide device that can be used.

Is covered with a side seal 8. Thereby, the concave groove forming the accommodating portion 24 is closed by the side seal 8.
Here, when the lubricant-containing member 18 is accommodated in the accommodating portion 24, the end portion of the lubricant-containing member 18 formed in a single string shape is disposed in the vicinity of the outer opening 28. In this case, as shown in FIG. 2, it is preferable that the end of the lubricant-containing member 18 protrudes from the outer opening 28 to the outside.

  The lubricant supply member 6 and the side seal 8 are disposed on the end surface in the moving direction of the slider 4 with the surface opposite to the mounting surface to the slider 4 of the lubricant containing member case 16 covered with the side seal 8. At this time, the bolt insertion hole 20 included in the lubricant-containing member case 16 and the hole formed in the end cap 14 and the side seal 8 through which the bolt used to attach the side seal 8 can be inserted. Similarly, the lubricant supply hole 22 included in the lubricant-containing member case 16 is matched with the hole formed in the end cap 14 and the side seal 8 through which the lubricant can move.

  Then, the bolt used for attaching the side seal 8 is inserted into the bolt insertion hole 20 provided in the lubricant-containing member case 16 and the holes formed in the end cap 14 and the side seal 8. Furthermore, the front end side of the bolt used for attaching the side seal 8 is screwed into a hole formed in the slider body 12 where the bolt used for attaching the side seal 8 can be screwed. As a result, the bolt used for attaching the side seal 8 passes through the side seal 8, the lubricant supply member 6 and the end cap 14, and is coupled to the slider main body 12, so that the side seal 8, the lubricant supply member 6 and the end are connected. The cap 14 is attached to the slider body 12.

When the side seal 8, the lubricant supply member 6, and the end cap 14 are attached to the slider body 12, a part of the lubricant-containing member 18 accommodated in the accommodating portion 24 protrudes from the inner opening portion 26, and the guide rail 2. It will be in the state which contacted the outer surface.
In this state, the lubricant contained in the lubricant-containing member 18 oozes out over time and is supplied to the outer surface of the guide rail 2 including the rail-side rolling element rolling surface 10. Further, when the slider 4 moves relative to the guide rail 2 during the operation of the linear guide device 1, the lubricant that exudes from the lubricant containing member 18 and is supplied to the outer surface of the guide rail 2 along with the relative movement. The agent is supplied to the rail-side rolling element rolling surface 10 along the axial direction of the guide rail 2.

  The lubricant supplied to the rail-side rolling element rolling surface 10 is supplied to the slider-side rolling element rolling surface along with the rolling of the rolling element in the load rolling path, so that the load rolling path and the rolling element Supplied between. The lubricant supplied between the load rolling path and the rolling element rolls as the rolling element moves from the load rolling path to the rolling element return path via the direction change path. Supplied to the entire road. Thereby, since it becomes possible to maintain the lubrication state of a rolling element rolling path and a rolling element, it becomes possible to suppress the operativity fall of the linear motion guide apparatus 1. FIG. Further, by maintaining the lubrication state between the rolling element rolling path and the rolling element, it is possible to suppress wear generated at the contact portion between the rolling element rolling path and the rolling element, and therefore, the linear motion guide device 1 It is possible to suppress a decrease in durability.

When the content of the lubricant in the lubricant-containing member 18 is reduced, such as when the linear motion guide device 1 is operated for a long time, the old lubricant-containing member 18 with the reduced content of the lubricant is replaced with the lubricant. Since it is necessary to replace with a new lubricant-containing member 18 containing a sufficient amount, the replacement operation is performed.
In the replacement operation of the lubricant-containing member 18, first, the old lubricant-containing member 18 whose lubricant content has been reduced is taken out from the accommodating portion 24.
At this time, in the state where the end of the lubricant-containing member 18 projecting outward from the outer opening 28 is gripped by an operator's hand or a tool such as tweezers, the housing portion 24 of the lubricant-containing member 18 is used. A portion accommodated in the inside is taken out through the outer opening 28. As a result, the old lubricant-containing member 18 having a reduced lubricant content is taken out of the housing portion 24 and taken out from the lubricant-containing member case 16.

After the old lubricant-containing member 18 is removed from the lubricant-containing member case 16, a new lubricant-containing member 18 sufficiently containing the lubricant is passed from the outside of the lubricant-containing member case 16 through the outer opening 28. It accommodates in the accommodating part 24. FIG. At this time, it is preferable that the end portion of the lubricant-containing member 18 protrudes from the outer opening 28 to the outside as in the assembly of the linear motion guide device 1.
Therefore, in the linear motion guide device 1 of the present embodiment, the old lubricant-containing member 18 is replaced with the new lubricant-containing member only by the operation with respect to the lubricant-containing member 18 without requiring the operation with respect to the slider 4 and the side seal 8. 18 can be exchanged.

(Effects of the first embodiment)
The effects of this embodiment are listed below.
(1) In the lubricant supply member 6 provided in the linear motion guide device 1 of the present embodiment, the old lubricant-containing member 18 housed in the housing portion 24 of the lubricant-containing member case 16 is replaced with the lubricant-containing member case. It is possible to take out the lubricant-containing member case 16 to the outside through the outer opening 28 that opens to the outer surface orthogonal to the mounting surface of the slider 16 to the slider 4. Further, the new lubricant-containing member 18 can be accommodated in the accommodating portion 24 from the outside of the lubricant-containing member case 16 through the outer opening 28.

For this reason, since it becomes possible to take out and store the lubricant-containing member 18 through the outer opening 28 with the lubricant-containing member case 16 attached to the slider 4, only the operation for the lubricant-containing member 18 is performed. Thus, the lubricant-containing member 18 can be replaced.
As a result, it is possible to improve the efficiency of the work of replacing the lubricant-containing member 18, and the maintenance work that suppresses the decrease in the operability and durability of the linear motion guide device 1 is facilitated.
Further, since the lubricant supply member 6 is formed from the lubricant-containing member 18 containing the lubricant and the lubricant-containing member case 16 having no movable part, the lubricant-containing member case 16 is formed by injection molding or the like. It becomes possible to create. For this reason, it becomes possible to make the structure of the lubricant supply member 6 simple and to make the structure with a small number of parts.

As a result, an increase in manufacturing cost of the lubricant containing member case 16 can be suppressed, and an increase in manufacturing cost of the linear motion guide device 1 can be suppressed.
Further, the lubricant-containing member 18 can be replaced while the side seal 8 is attached to the slider 4 via the lubricant supply member 6.
As a result, even when the lubricant-containing member 18 is replaced, the positioning state of the side seal 8 with respect to the guide rail 2 can be maintained, so that a gap is generated between the side seal 8 and the guide rail 2. Can be suppressed. Thereby, it becomes possible to suppress the dust-proof performance fall of the linear motion guide device 1.

(2) In the lubricant supply member 6 provided in the linear motion guide device 1 of the present embodiment, the outer surface of the lubricant containing member case 16 orthogonal to the attachment surface to the slider 4 is orthogonal to the upper surface of the slider 4. An outer opening 28 that communicates with the accommodating portion 24 opens on the surface to be opened.
For this reason, the outer side opening part 28 will open in the side surface which is a surface which does not oppose the table attached to the upper surface of the slider 4, the base which installs the guide rail 2, etc. FIG.
As a result, the outer opening 28 contains a lubricant as compared with the case where the outer opening 28 opens on the upper surface facing a member such as a table attached to the upper surface of the slider 4 or the lower surface facing the base on which the guide rail 2 is installed. It is possible to secure a wide space for the replacement work of the member 18.
Thereby, it becomes possible to improve the efficiency of the operation | work which replaces the lubricant containing member 18, and the maintenance operation | work which suppresses the operativity and durability of the linear motion guide apparatus 1 becomes easy.

Moreover, it is not necessary to employ a space in the axial direction of the guide rail 2 or a narrow space formed between the upper surface of the slider 4 and the guide rail 2 as a space for exchanging the lubricant-containing member 18.
As a result, regardless of the structure of the linear motion guide device 1, the lubricant containing member 18 can be replaced.

It is possible to suppress a decrease in assembly work efficiency of the guide device 1.
(4) In the lubricant supply member 6 provided in the linear motion guide device 1 of the present embodiment, the lubricant-containing member 18 is formed in a string shape, so that the lubricant-containing member 18 corresponds to, for example, the shape of the slider 4. The lubricant-containing member 18 can be easily formed as compared with the case where it is formed in a substantially U shape.
As a result, the manufacturing efficiency of the lubricant-containing member 18 can be improved, and the manufacturing cost of the lubricant-containing member 18 can be reduced.
If a part of the lubricant-containing member 18 formed in a string shape can be brought into contact with the outer surface of the guide rail 2, the shape of the lubricant-containing member 18 needs to correspond to the shape of the guide rail 2. Disappear.

For this reason, it is necessary to form a plurality of types of lubricant-containing members 18 corresponding to the shapes of the guide rails 2 having different outer surface shapes, such as the guide rails 2 having different shapes of the rail-side rolling elements rolling surface 10. Disappears.
As a result, the manufacturing efficiency of the lubricant-containing member 18 can be improved, and the manufacturing cost of the lubricant-containing member 18 can be reduced.
Further, like the lubricant supply member 6 provided in the linear motion guide device 1 of the present embodiment, the lubricant containing member 18 is formed in a single string shape, thereby allowing the accommodating portion 24 to pass through the outer opening 28. It becomes easy to take out the lubricant-containing member 18 accommodated in the container.
As a result, in the replacement operation of the lubricant-containing member 18, the operation of taking out the lubricant-containing member 18 from the accommodating portion 24 is facilitated, so that it is possible to suppress a decrease in the assembly work efficiency of the linear motion guide device 1. .

(5) In the linear motion guide device 1 of the present embodiment, the lubricant-containing member 18 can be taken out and stored through the outer opening 28 with the lubricant-containing member case 16 attached to the slider 4. Become.
For this reason, it becomes possible to replace the lubricant-containing member 18 only by the work on the lubricant-containing member 18, and it is possible to replace the lubricant-containing member 18 only by the work on the lubricant-containing member 18 without requiring work on the slider 4 or the like. The member 18 can be exchanged.
Moreover, it becomes possible to reduce the necessity of re-positioning the members attached to the slider 4 other than the lubricant-containing member 18 such as the side seal 8.

The lubricant containing member 18 is formed of a plurality of particles. Specifically, a plurality of granules are formed from a polymer material such as polyurethane rubber and polyolefin resin, and a lubricant is contained in these granules. In addition to the polymer material, the plurality of particles may be formed from a porous resin formed using felt, ethylene, or the like.

The particle size of each particle is formed larger than the gap formed between the guide rail 2 and the slider 4 and the lubricant-containing member case 16. Thereby, it becomes possible to prevent each granule forming the lubricant-containing member 18 from dropping out from the gap formed between the guide rail 2 and the slider 4 and the lubricant-containing member case 16. .
The outer opening 28 is closed with a lid member (not shown). The lid member may be inserted into the outer opening 28 to close the outer opening 28, or may be attached to the outside of the lubricant-containing member case 16 to close the outer opening 28.

Displacement is free. Thereby, for example, even when the outer surface of the guide rail 2 has a complicated shape, such as when the rail-side rolling element rolling surface 10 has a complicated shape, the guide rail 2 has a corresponding shape. The lubricant-containing member 18 can be brought into contact with the outer surface.
