Description

  TECHNICAL FIELD The present invention relates to a method for injecting grease into a lubrication part, a grease nipple for carrying out this grease injection method, a grease container, and the like, and in particular, a grease injection method and a grease nipple suitable for a lubrication part having a high frequency of grease injection. , A grease nipple socket, a grease container, and a grease injection kit including them.

Conventionally, the following two methods have been mainly employed when injecting grease into a lubrication part in various machines such as machine tools and construction machines.
As a first method, a grease nipple as disclosed in Patent Document 1 is attached to the lubricating portion, and grease is injected through the grease nipple. For a grease nipple as disclosed in Patent Document 1, grease is injected using a grease gun. The grease gun includes a filling container for filling a predetermined amount of grease, an extrusion lever for pushing out the grease filled in the filling container, and an injection for injecting the grease pushed out from the filling container into the grease nipple. A grease injection jig having a nozzle. The grease injection port of the grease nipple is formed in an abacus bead shape, and the injection nozzle of the grease gun is formed so as to be fitted to the injection port of the grease nipple.

  A grease injection method using the grease gun having such a configuration is as follows. First, grease is filled in a grease gun filling container. Next, the tip of the injection nozzle of the grease gun is fitted or pressed against the injection port of the grease nipple. Then, the grease filled in the filling container is pushed out by operating the extrusion lever of the grease gun. As a result, the grease filled in the filling container is injected into the grease nipple and then injected into the lubrication part via the grease nipple.

  According to such a grease injection method, there is an advantage that grease can be injected into a plurality of lubrication parts in a short time.

  The second method is a method of injecting grease using a nipple (grease cup) provided with a cup capable of storing a small amount of grease and a lid body screwed into the cup. The method of injecting grease using such a grease cup is as follows. First, grease is filled in the cup and the lid. After the grease is filled, the lid is screwed into the cup, so that the grease is pushed out from the nipple by the tightening of the lid and injected into the lubrication part. It should be noted that a grease that forcibly automatically adds grease filled in a cup, such as a glister, can be regarded as an example of a grease cup.

According to such a method of injecting grease, since the cup and the lid can be filled with grease, there is an advantage that no special jig such as a grease gun is required when filling the grease.

  The grease injection method described as the first method is considered to be very effective when grease is continuously injected into a plurality of lubrication parts. However, as described above, the first method requires a special tool such as a grease gun when injecting the grease into the grease nipple, and thus there is a problem that it is troublesome. In addition, the grease injection by the grease gun depends on experience, and the grease cannot be injected into the inlet of the grease nipple and may leak out.

  Further, unlike the first method, the grease injection method described as the second method does not require a special jig for the grease injection, but the following problems may occur. That is, in the grease injection method described as the second method, when the grease is filled, the cup and the lid are opened. At this time, dust, cutting powder, etc. are mixed into the cup and the lid. There is a fear. In addition, because it is easy to fill grease on site, the worker may fill the cup or lid with grease with bare hands, etc., and in such a case, dust or cutting powder may be mixed. . When dust or cutting powder is mixed into the cup or the lid, the dust or the like is supplied to the lubrication unit together with the grease, which may cause damage to the lubrication unit.

  An object of the present invention is to provide a grease injection method that solves the above-mentioned problems, can easily inject grease without using a special jig, and can always keep the grease to be injected in a clean state.

Moreover, since the grease supplied to the lubrication part is not exposed to the outside, the grease can be kept clean.

  In the grease injection method as described above, the grease container is preferably attached to the grease nipple until the grease enclosed in the container is exhausted. By eliminating the act of attaching and detaching the grease container when the grease remains in the container, it is possible to avoid a situation where dust or the like is mixed into the grease as the grease container is attached or detached. For this reason, it is possible to always keep the grease supplied to the lubrication part in a clean state.

  In addition, the grease nipple according to the present invention, which is used when performing the grease injection method as described above, is formed in a cylindrical shape, and one end side is an attachment portion and the other end side is an injection portion.

With such a configuration, the grease container can be directly or indirectly attached to the grease nipple. For this reason, the grease injection method as described above can be performed, and the grease can be supplied to the lubricating portion without using a special jig. Also, the supplied grease can be always clean.

  Further, when performing the above-described grease injection method, the grease nipple socket according to the present invention may be used. The grease nipple socket according to the present invention is a cylindrical body for indirectly connecting the screw portion provided in the injection portion of the grease nipple as described above and the screw portion provided in the extraction port of the grease container. And what is necessary is just to equip the both ends of the said cylinder with the female screw part or male screw part of the same diameter or different diameter, respectively. With the socket having such a configuration, it is possible to connect both the grease nipple injection portion and the grease container extraction port even when the caliber is different. For this reason, the freedom degree in implementing the above grease injection methods can be improved.

  Moreover, when implementing the above grease injection | pouring methods, it is good to use the grease container which concerns on this invention.

  Further, the grease injection kit having the above-described configuration may be provided with squeezing means for squeezing the grease contained in the grease container. With this configuration, it is possible to efficiently supply the grease contained in the grease container.

According to the above grease injection method, it is possible to inject grease without using a special jig. Moreover, the grease to be injected (supplied) can be always clean.
Moreover, according to the grease injection kit of the above structure, the above grease injection method can be implemented.

  Hereinafter, embodiments of the grease injection method, the grease nipple, the grease nipple socket, the grease container, and the grease injection kit of the present invention will be described with reference to the drawings. The following embodiments are some embodiments according to the present invention, and the present invention assumes various forms as long as the configuration of the main part is not changed.

  First, with reference to FIG. 1, a first embodiment according to a grease injection kit for carrying out the grease injection method of the present invention will be described. The grease injection kit 100 of this embodiment includes a grease nipple 10 attached to a screw hole provided in a lubrication part, a socket 30 attached to the grease nipple 10, and a container 50 filled with grease to be injected.

  The detailed configuration of the grease nipple 10 of the present embodiment is as shown in FIG. 2A is a front view showing a partial cross section, and FIG. 2B is a plan view. The grease nipple 10 according to this embodiment includes a cylindrical main body 12 having a through hole in the center in the longitudinal direction, a check valve that closes an opening of a through hole formed at one end of the main body 12, and It is basically provided with urging means for pressing the check valve against the opening.

  The main body 12 has male screw portions 16a and 14a formed with screw grooves on the outer peripheral surfaces of both end portions of the cylindrical body (the attachment portion 16 and the injection portion). A flange portion 18 is formed at the boundary between the male screw portions 16a and 14a and in the vicinity of the center in the longitudinal direction of the cylindrical body. The flange portion 18 may have a shape that can be gripped and rotated with a jig such as a spanner or a wrench. For example, the flange portion 18 may have a hexagonal shape as shown in FIG. As shown in FIG. 2 (A), the through hole formed in the cylindrical body is formed so that both end portions thereof are slightly narrowed, and a spherical body (steel ball) 20 as a check valve is formed inside. A string spring 22 as an urging means is provided. The through hole has a grease injection port (injection port) 14 on one side of the opening provided at both ends of the cylinder, and the steel ball 20 is provided inside the opening on the injection port 14 side. The steel ball 20 closes the injection port 14 by coming into contact with the constricted portion 12a of the injection port 14, and forms a grease conduction path by separating from the constricted portion 12a. With respect to the steel balls 20 arranged in this way, the string spring 22 is provided so as to apply a pressing force that presses the steel balls 20 against the constricted portion 12b. More specifically, one end portion of the coiled spring 22 is placed on the constricted portion 12b provided on the attachment portion 16 on the opposite side of the injection port 14 as a spring seat. The other end of the string spring 22 is brought into direct or indirect contact with the steel ball 20 so as to press the steel ball 20 against the constricted portion 12a using the elastic force of the spring. .

  In the grease nipple 10 having the above-described configuration, the end portion (injection portion) on the injection port 14 side is formed flat or convex, thereby facilitating wiping off the grease adhering during the grease injection. For this reason, it becomes easy to maintain the injection port 14 in a clean state, and it becomes possible to prevent dust and dust from being mixed into the lubrication part.

  Next, a detailed configuration of the socket 30 in the present embodiment will be described with reference to FIG. 3A is a front sectional view of a single socket, and FIG. 3B is a diagram showing a state in which the socket is connected to the above-described grease nipple.

  The socket 30 of the present embodiment is a connection tool (joint) for connecting the above-described grease nipple 10 and a grease container 50 described later in detail. The socket body 32 is a cylindrical object having a through hole 34 in the center. In the case of the socket 30 of the present embodiment, the diameters of the two openings 38 and 36 provided at both ends of the through hole 34 are made different from each other, respectively, and the inlet 14 (see FIG. 2) of the grease nipple 10 and the grease container Thread grooves 38a and 36a that can be screwed together with both of the 50 extraction ports 52 (see FIG. 4) are formed. Therefore, the openings 38 and 36 of the through hole 24 provided in the socket 30 can be set as a grease nipple connection part (opening part) 38 and a grease container connection part (opening part) 36, respectively. The outer shape of the socket 30 of the present embodiment may be a straight cylindrical body, but is preferably a shape that can be gripped and rotated by a spanner, a wrench, or the like. For this reason, in this embodiment, the flange part 40 was provided in the outer peripheral part of the socket 30, and the said flange part 40 was formed in the hexagon (not shown).

  In the socket 30 of the present embodiment, the grease nipple connecting portion 38 and the grease container connecting portion 36 have been described as having different diameters, but the same diameter may be used depending on the diameter of the corresponding screw portion. It goes without saying that it belongs to a part of the embodiment.

Next, the grease container in the present embodiment will be described with reference to FIG. In FIG. 4, FIG. 4 (A) shows a front view, and FIG. 4 (B) shows a side view.
The grease container 50 according to the present embodiment includes a container main body 54 that packages a predetermined amount of grease, and an extraction port 52 for extracting the grease from the container main body 54. The container main body 54 is configured by a flexible member, and the container main body 54 is bent by pressing the container main body 54 to reduce the volume inside the container main body 54, and the contained grease is discharged from the extraction port 52. A configuration that can be extracted is preferable. The shape of the container main body 54 is not particularly limited, but for example, a shape like a so-called toothpaste tube as shown in FIG. 4 is convenient for extracting grease.

  The extraction port 52 is formed in a cylindrical shape, and a screw groove 52a is formed on the outer periphery thereof. This enables connection to the socket 30 (see FIG. 3) described above. The size of the grease container 50 having such a configuration can be varied depending on the amount of grease to be included, the amount of grease used in the lubrication part to which the grease is injected, and the like. More specifically, the size of the container may be changed so that the internal volume becomes an appropriate amount as the amount of grease contained is changed to 10 g, 15 g, 20 g,. In addition, the grease container extraction port 52 has a sealed structure that is opened during use (for example, the extraction port 52 is sealed by a thin film), so that the contained grease does not deteriorate due to oxidation or the like. . For this reason, even when a large amount of stock is stocked, good quality grease can always be supplied to the lubrication part when used.

  In the above description, the size of the container is changed in accordance with the amount of grease contained in the container. However, the size of the container may be constant regardless of the amount of grease contained. In this case, the size of the container is set according to the maximum amount of grease that is expected to be contained, and when the amount of inclusion is less than this amount, an empty area in the container is filled with an inert gas or the like. Therefore, it is recommended that the grease not deteriorate. By configuring the grease container 50 in this manner, the size of the container body 54 can be unified, and the manufacturing cost can be reduced.

  The grease injection kit 100 including the grease nipple 10, the socket 30, and the grease container 50 as described above is used as follows.

  First, the grease nipple 10 is screwed into a screw hole (not shown) provided in the lubrication part. Next, the socket 30 is screwed into the inlet 14 of the grease nipple 10. By attaching this socket 30, it is possible to selectively connect both of them without questioning the difference in diameter between the inlet 14 of the grease nipple 10 and the extraction port 52 of the grease container 50 or the difference in thread groove. It becomes.

  The socket 30 may be attached by screwing the screw groove 38a provided in the grease nipple connecting portion 38 to the male screw portion 14a provided in the inlet 14 of the grease nipple 10.

  After attaching the socket 30 to the grease nipple 10, the extraction port of the grease container 50 is screwed into the grease container connecting portion of the socket 30, and the grease container is attached to the socket.

  In the grease injection kit 100 configured by the grease nipple 10, the socket 30 and the grease container 50 set as described above, the container body 54 of the grease container 50 is pressed against the container body 54 of the grease container 50 by pressing the container body 54 of the grease container 50. The contained grease is pushed out of the grease container 50 through the extraction port 52. The grease pushed out of the grease container 50 passes through the socket 30 and flows into the grease nipple 10 through the inlet 14 of the grease nipple 10. Then, the grease that has flowed into the grease nipple 10 passes through the through hole in the grease nipple 10 and is supplied to the lubricating portion.

  In the grease injection kit 100 as described above, if all of the grease contained in the container main body 54 of the grease container 50 is pushed out of the container main body 54 but there is not enough grease to be supplied to the lubrication part, the By removing the grease container 50 and attaching a new grease container 50 to the socket 30, it becomes possible to supply a necessary amount of grease to the lubrication part.

  In such a grease injection kit 100, since the grease is directly injected (supplied) into the grease nipple 10 (lubricating part) by pressing the grease container 50, a special jig such as a grease gun that has been conventionally used is used. It becomes possible to inject grease without using. Moreover, since the grease supplied to the lubrication part is not exposed to the outside, dust or the like is not mixed into the grease. For this reason, the grease supplied to the lubrication part can be always clean. Further, since the grease is not directly touched, the situation where the operator's hand or clothes are soiled by the grease does not occur. In addition, by making the grease container 50 sealable, the grease can be stored in a good state for a long time. Further, if the grease container 50 is made small, there is little possibility of affecting the control of the equipment even when the grease container 50 is still attached to the grease nipple 10, so that the grease container 50 can be attached and removed. Can be saved. Furthermore, since the grease is supplied by the grease container 50 containing the subdivided grease, it is possible to maintain the state where the grease container 50 is attached to a plurality of lubrication parts, unlike the case of using a jig such as a grease gun. it can.

  Next, a second embodiment according to the grease injection kit of the present invention will be described with reference to FIG. The grease injection kit 100a of this embodiment is comprised from the grease nipple 10 and the grease container 50a so that it can read also from FIG. In this embodiment, the configuration of the grease nipple 10 is the same as that of the grease nipple 10 shown in the first embodiment, and a part of the configuration of the grease container 50a is different from that of the grease container 50 shown in the first embodiment. ing. Therefore, the detailed description regarding the grease nipple 10 is omitted in the present embodiment.

  The detailed configuration of the grease container 50a according to the present embodiment is as follows. The configuration of the container in the grease container 50a of the present embodiment is the same as that of the grease container 50a in the first embodiment described above. On the other hand, the structure of the extraction port 56 is screwed into a male screw portion 14a formed in the injection port 14 (see FIG. 2) of the grease nipple 10 in order to enable direct connection to the grease nipple 10. A possible female screw portion (thread groove) 56a is formed.

  Since the extraction port 56 of the grease container 50a is configured as described above, the grease container 50a can be directly attached to the grease nipple 10 as shown in FIG. According to the grease injection kit 100a having such a configuration, the configuration when supplying grease can be made more compact. Moreover, since the members which comprise a kit can be reduced, it can manufacture now at low cost.

  Although not shown, a lid (cap or the like) that seals the extraction port 56 may be attached to the grease container 50a configured as in the present embodiment to protect the female screw portion 56a. By adopting such a configuration, even when the storage period of the grease container 50a is long, dust and dust do not accumulate at the extraction port 56, and the grease supplied to the lubrication part is clean. It can be. Other operations and effects are the same as those of the grease injection kit 100 in the first embodiment described above.

  A grease squeezing jig as shown in FIG. 6 may be attached to the grease injection kit 100, 100a having the above-described configuration. 6A is a front view of the grease squeezing tool, FIG. 6B is a side view of the grease squeezing tool, and FIGS. 6C and 6D are states of using the grease squeezing tool, respectively. FIG.

The grease squeezing jig 60 shown in FIG. 6 has a frame 62, rollers 64 (64a, 64b), and a handle 68 for rotating the roller 64 as a basic configuration.
The frame 62 is composed of two frame members 62a and 62b formed in a U-shape. The frame members 62a and 62b are configured so that the ends of the U-shapes are pivotably connected to each other to constitute a frame 62. The constructed frame 62 rotates with a rotation center 70 as a base point, Like a hinge, the two frame members 62a and 62b are movable to a position where they overlap each other.

  The rollers 64a and 64b are provided symmetrically with respect to the two frame members with the two rotation centers 70 as base points. A plurality of irregularities formed along the longitudinal direction of the rollers 64a and 64b are provided on the outer periphery of the rollers 64a and 64b. For this reason, when the frame members 62a and 62b overlap with each other as they rotate, the irregularities formed on the two rollers 64a and 64b are engaged with each other.

  The handle 68 is provided on the frame 62, and is connected to one of the two rollers 64a and 64b (the roller 64a in the figure). The handle 68 is connected to the rotation shaft 66 of the rollers 64a and 64b, so that the power applied to the handle 68 can be transmitted to the roller 64a. As described above, the roller 64a and the roller 64b are in a state in which the concave and convex portions are engaged with each other when the frame 62 is folded. Therefore, by rotating the handle 68 and rotating the roller 64a, the roller 64b is also rotated at the same time.

  In the grease squeezing jig 60 having the above-described configuration, the grease container 50 (or the grease container 50a) is interposed between the roller 64a and the roller 64b, and the frame 62 is folded. In this state, the grease container 50 is sandwiched between the rollers 64a and 64b. After the grease container 50 is sandwiched between the two rollers 64a and 64b, the rollers 68a and 64b are possible by rotating the handle 68 provided on the frame 62 in a fixed direction (counterclockwise in the case of FIG. 6). The container body 54 having flexibility can be bitten and the grease contained in the container body 54 can be squeezed out. In addition, by providing irregularities on the outer peripheral surfaces of the rollers 64a and 64b, the container main body 54 can be surely bitten, and when the rollers 64a and 64b are rotated, the container main body 54 and the rollers 64a and 64b are spaced from each other. Therefore, the possibility of slipping can be reduced, and the grease can be squeezed out efficiently.

  By attaching the grease squeezing jig 60 as described above to the grease injection kit 100 or the grease injection kit 100a described above, it is possible to easily inject grease even when the grease injection pressure is high. it can. Further, unlike the squeezing by hand, it is possible to squeeze without leaving the grease contained in the container body 54 (or reducing the amount to be left).

  The grease squeezing jig that exerts the above-described effects in the grease injection kit may be one that uses a roller for the squeezing portion as in the above embodiment, but may be one that is attached with a rubber spatula or the like instead of the roller. . In such a configuration, the container main body 54 cannot be bitten, but the container main body 54 can be sandwiched between rubber spats facing each other. Therefore, the grease contained in the container main body 54 can be squeezed out by sliding the frame to the extraction port 52 side with the container main body 54 sandwiched between the rubber spats. That is, according to the grease squeezing jig having such a configuration, the grease can be squeezed out without giving an operation of “rotation”. Note that the same effect can be obtained even when a roller without irregularities is used instead of the rubber spatula.

  Further, the grease squeezing jig 60 configured as described above may be provided with a guide 63 as indicated by a broken line in FIG. By providing the guide 63, the container body 54 after squeezing out the grease can be smoothly guided to the outside of the frame 62. By providing the guide 63, the container body 54 after squeezing out the grease does not come into contact with the hand holding the frame.

  Further, the grease squeezing jig 60 shown in FIG. 6 is provided with a handle 68 on the rotating shaft 66 of the roller 64a, and rotating the handle 68 causes the container body 54 to be bitten into the rollers 64a and 64b to squeeze out the grease. Described. However, the grease squeezing jig according to the present embodiment may not have the handle 68. As described above, even in a grease squeezing tool having no handle 68, the container body 54 is sandwiched between the rollers 64a and 64b, the frame 62 is gripped, and the grease squeezing jig is extracted from the grease container 50. By pushing toward the mouth 52 (see FIG. 4), the rollers 64 a and 64 b attached to the frames 62 a and 62 b rotate while biting the container body 54, and the grease is squeezed out from the container body 54. Even in such a case, as described above, by providing the guide 63 on the frame, the container main body 54 after the grease is squeezed out does not come into contact with the hand holding the frame 62 or the like. .

  Needless to say, the grease squeezing jig that can be used for the above-described grease injection kit 100 or grease injection kit 100a is not limited to the above-described one. Various configurations of the grease squeezing jig can be conceived, but a specific configuration of another example is shown in FIG.

7A is a side view, FIG. 7B is a front view, FIG. 7C is a plan view, and FIG. 7D is a usage state of the grease squeezing tool. It is a reference figure.
The grease squeezing jig 80 of this example has a frame 82, a winding roller 84, a guide roller 86, and a handle 88 as a basic configuration. The frame 82 only needs to be able to accommodate a take-up roller 84 to be described later. In this example, the frame 82 has a rectangular box shape, and an inlet 82a for guiding a grease container to be squeezed into the frame 82 at the bottom. Was provided.

  The winding roller 84 is a drum for winding the container main body 54 of the grease container 50 (or 50a) around the outer periphery thereof, and a notch for inserting the end of the container main body 54 of the grease container 50 on the peripheral surface thereof. 84a is provided. By inserting the end of the container body 54 of the grease container 50 into the notch 84a, a trigger for winding the grease container 50 with the winding roller 84 can be created.

  The guide roller 86 is a roller provided in an introduction port 82 a provided in the frame 82, and guides the container body 54 taken up by the take-up roller 84 so as to be smoothly introduced into the frame 82. Take a role.

  The handle 88 is provided outside the frame 82 and is connected to the rotating shaft of the winding roller 84. For this reason, the winding roller 84 can be rotated by rotating the handle 88.

  When the grease squeezing jig 80 having the above-described configuration is used, the end of the container body 54 in the grease container 50 introduced into the frame 82 from the introduction port 82a is inserted into the notch 84a of the winding roller 84, and the handle 88 is rotated. . As a result, the container main body 54 of the grease container 50 is wound around the outer periphery of the take-up roller 84, and the contained grease is squeezed out.

  In the said embodiment, the shape like a toothpaste tube was mentioned as an example and demonstrated about the grease container as a shape of a container main body. However, the shape of the container body described above is merely an example of the container body, and the shape of the container body may be as shown in FIG. Specifically, the container body 94 of the grease container 90 is formed of a cylindrical flexible member, and the side surface of the cylindrical container is formed in a bellows shape. By forming a bellows portion in the container body 94 and making the length of the container body 94 extendable in the longitudinal direction, the effective grease can be obtained by pressing the end of the container body 54 when pushing out the included grease.
