Description

  The present invention relates to a lubricating device, and more particularly to a lubricating device for supplying lubricating oil to a member to be lubricated.

In an apparatus using mechanical parts, supply of lubricating oil may be required in order to suppress wear of the parts. For example, in a transmission having a large number of gears and sliding members, a lubrication device is mounted in order to suppress wear of these mechanical parts.
This type of transmission has a shaft, a sleeve yoke attached to the end of the shaft, an extension bush, and an extension case. The extension bush is attached to the case and slides with the sleeve yoke. Thus, the end of the shaft is supported so as to be rotatable with respect to the case.
In consideration of lubrication of the sliding surface of the extension bush, a lubrication structure described in Patent Document 1 has been proposed. In this lubrication structure, the extension bush is immersed in the lubricating oil accumulated on the sleeve yoke side in the extension case during normal running of the vehicle. For this reason, for example, when the lubricating oil is tilted toward the transmission case during a downhill, the extension bush can be lubricated using the lubricating oil accumulated during normal traveling.
Japanese Patent Publication No.58-38671

However, in the configuration described in Patent Document 1, the amount of lubricating oil to the extension bush is determined by the inclination of the vehicle, and there is a case where sufficient lubricating oil cannot always be supplied.
The subject of this invention is providing the lubrication apparatus which can improve lubrication performance.

A lubricating device according to the present invention is a device for supplying lubricating oil to a member to be lubricated, and includes a rotating member, a first guide member, a second guide member, and a case. The rotating member can contact the lubricating oil. The first guide member is disposed on the outer peripheral side of the rotating member so as to cover at least a part of the rotating member, and is disposed so as to face the rotating member in the radial direction. The second guide member is fixed to the first guide member, and guides the lubricating oil that reaches the first guide member to the member to be lubricated. The case accommodates the rotating member, the first guide member, and the second guide member.
In this lubricating device, the lubricating oil scraped up by the rotating member flows through the first guide member and into the second guide member. The lubricating oil that has flowed into the second guide member is guided to the member to be lubricated by the second guide member. For this reason, lubricating oil can be stably supplied to a to-be-lubricated member at the time of normal driving | running | working, and lubricating performance can be improved.

  As described above, in the lubricating device according to the present invention, the lubricating performance can be enhanced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the following description, the left direction in FIG. 1 is defined as the front, and the right direction in FIG. 1 is defined as the rear. Moreover, since the up-down direction of FIG. 1 corresponds with the state in which the transmission 1 is mounted on the vehicle, the up-down direction and the left-right direction in the following description are the states in which the transmission 1 is mounted on the vehicle. It means the up and down direction and the left and right direction.
The transmission 1 is a manual transmission for an FR (Front Engine Rear Drive) vehicle capable of 6-speed shifting. Specifically, as shown in FIG. 1, the transmission 1 mainly includes a case 2, an input shaft 3, a counter shaft 4, a main shaft 8, a plurality of gears G1 to G17, and a plurality of synchro mechanisms S1.

The third sync mechanism S3 is a mechanism for connecting the sixth speed main gear G6 or the main shaft 8 to the input shaft 3.

The main shaft 8 is a shaft for outputting power, and is supported by the second case 22 via bearings 51 and 56 so as to be rotatable about the rotation axis A1. The front end portion of the main shaft 8 rotatably supports the rear end portion of the input shaft 3. A main drive gear G7 is provided on the main shaft 8 so as to be integrally rotatable.
The main shaft 8 is also supported by the extension case 23 via an extension bush 89. Specifically, a sleeve yoke 88 is attached to the rear end portion of the main shaft 8. An extension bush 89 is inserted on the outer peripheral side of the sleeve yoke 88. As shown in FIG. 2, the extension bush 89 has an oil hole 89a penetrating in the radial direction. The oil hole 89 a communicates with a plurality of grooves (not shown) formed on the inner peripheral surface of the extension bush 89. When the lubricating oil flows into the oil hole 89a, the lubricating oil flows between the extension bush 89 and the sleeve yoke 88 through the groove. As described above, even when the lubricating oil is supplied to the outer peripheral portion of the extension bush 89, the lubricating oil is guided to the sliding surface of the extension bush 89 by the oil hole 89a.

  The counter shaft 4 is supported by the first case 21 and the second case 22 via bearings 54 and 52 so as to be rotatable about the rotation axis A2. The counter shaft 4 is provided with a fourth speed counter gear G14, a third speed counter gear G13, a sixth speed counter gear G16, and a counter drive gear G17 so as to be integrally rotatable. The counter shaft 4 supports the reverse counter gear G15, the first speed counter gear G11, and the second speed counter gear G12 so as to be rotatable. The counter shaft 4 supports the fourth sync mechanism S4 and the first sync mechanism S1.

The second speed main gear G2 is a gear used during second speed travel, and meshes with the second speed counter gear G12. The third speed main gear G3 is a gear used during the third speed traveling, and meshes with the third speed counter gear G13. The fourth speed main gear G4 is a gear used during the fourth speed traveling, and meshes with the fourth speed counter gear G14. The reverse main gear G5 is a gear used during reverse travel, and meshes with the reverse counter gear G15. The sixth speed main gear G6 is a gear used when traveling at the sixth speed, and meshes with the sixth speed counter gear G16.
The counter drive gear G17 is a gear for transmitting the power transmitted to the input shaft 3 to the main shaft 8 via the main drive gear G7, and meshes with the main drive gear G7. The reverse main gear G5 is a gear used during reverse travel, and meshes with the reverse counter gear G15. Note that when traveling in the fifth speed, the input shaft 3 and the main shaft 8 are directly connected by the third synchronization mechanism S3.

In order to supply lubricating oil into the extension case 23, the gear chamber 28 is provided with an oil garter 9. The oil garter 9 is a member having a hook-like shape extending in the axial direction, and extends from the vicinity of the reverse main gear G5 into the extension case 23. A part of the lubricating oil scraped up by each gear and the synchro mechanism is guided to the extension case 23 by the oil garter 9. As a result, lubricating oil is accumulated in the lower part of the extension case 23.
<Lubrication system configuration>
The transmission 1 is equipped with a lubrication device L for supplying lubricating oil to the sliding surface of the extension bush 89. The lubricating device L is disposed in the extension case 23 and includes a rotating member 6 and a guide member 7.

The rotating member 6 is a resinous member fixed to the main shaft 8, and includes four oil catchers 61 that collect the lubricating oil accumulated in the extension case 23, a disk portion 64, a cylindrical portion 63, and 4 Two stirring blades 62 (an example of a blade portion). In this embodiment, each part of the rotating member 6 is integrally formed.
The oil catcher 61 has a collection opening 61a that opens in the rotational direction, and a hole 61b that guides the lubricating oil radially inward. The four oil catchers 61 are arranged at an equal pitch in the circumferential direction. The lubricating oil collected by the oil catcher 61 passes through the inlet oil passage 82 and the main oil passage 81 formed in the main shaft 8, the fourth speed main gear G 4, the third speed main gear G 3 and the sixth speed main gear G 6. Is supplied to a needle bearing that supports The lubricating oil collected by the oil catcher 61 is also supplied to the needle bearing disposed between the main shaft 8 and the input shaft 3 via the main oil passage 81.

The stirring blade 62 is a plate-like portion that extends radially outward from the cylindrical portion 63, and is disposed behind the oil catcher 61 in the axial direction. The four stirring blades 62 are arranged at an equal pitch. The stirring blade 62 extends to the same radial position as the oil catcher 61. The radially outer end of the stirring blade 62 is inclined along an inner peripheral surface 71 a of a collecting member 71 (described later) of the guide member 7.
The guide member 7 includes a collection member 71 (an example of a first guide member) disposed in the extension case 23 and a garter member 72 (an example of a second guide member) fixed to the collection member 71. is doing. The collection member 71 and the garter member 72 are made of resin. In the present embodiment, the collecting member 71 is a separate member from the garter member 72.
The collecting member 71 has a shape along the inner wall of the tapered portion 23 a of the extension case 23. Specifically, the collection member 71 is a cylindrical member whose inner diameter gradually decreases toward the rear side in the axial direction. The collection member 71 is disposed so as to cover the outer side in the radial direction of the rotating member 6, and faces the rotating member 6 in the radial direction. The collecting member 71 has a first portion 71b disposed on the side where the rotating member 6 scoops up the lubricating oil. For example, the first portion 71b is a half on the scraping side with respect to the rotation axis A1. At least a part of the first portion 71b is immersed in the lubricating oil. Moreover, the collection member 71 has a hole 71d disposed on the opposite side of the first portion 71b with respect to the rotation axis A1. A garter member 72 is inserted into the hole 71d.

The garter member 72 has a shape like a ridge extending in the axial direction, and penetrates the hole 71 d of the collecting member 71. The garter member 72 is disposed on the opposite side of the first portion 71b with respect to the rotation axis A1. An end portion on the front side of the garter member 72 is disposed on the axially rear side of the rotating member 6. The rear end of the garter member 72 is disposed in the vicinity of the extension bush 89. The garter member 72 has a bottom plate 73, a first side wall 74, and a second side wall 75.
The bottom plate 73 is inclined so as to descend toward the extension bush 89. The first side wall 74 and the second side wall 75 are disposed on both sides of the bottom plate 73. The first side wall 74 extends to the vicinity of the center of the extension bush 89 in the axial direction. The second side wall 75 extends to the front side of the extension bush 89. The front side end of the first side wall 74 is disposed in the hole 71 d of the collecting member 71, but does not protrude from the inner peripheral surface 71 a of the collecting member 71 to the front side in the axial direction. For this reason, the front end portion of the bottom plate 73 is disposed in the radial direction close to the inner peripheral surface 71a in a state where there is almost no gap between the end plate 73 and the inner peripheral surface 71a of the collecting member 71. That is, a part of the collecting member 71 forms a side wall of the garter member 72 in place of the first side wall 74 at the front side end of the garter member 72. When this portion is defined as the inlet portion 78, the lubricating oil that has flowed through the collection member 71 flows into the garter member 72 from the inlet portion 78.

Here, the state in which the bottom plate 73 is disposed in the vicinity of the inner peripheral surface 71a means that there is no gap between the bottom plate 73 and the inner peripheral surface 71a, as well as the bottom plate 73 and the inner peripheral surface 71a. Also includes a state in which there is a gap between them. Even when there is a gap, when at least a part of the lubricating oil that has flowed through the inner peripheral surface 71a flows onto the bottom plate 73, the bottom plate 73 is disposed close to the inner peripheral surface 71a. It can be said that it is in a state.
The garter member 72 further includes a notch 76, a stopper 77, and a pressing part 74a. The notch 76 is a part of the rear end of the garter member 72 that is notched, and is disposed around the oil hole 89 a of the extension bush 89. The stop portion 77 is disposed on the rear side of the bottom plate 73 and guides the lubricating oil flowing in the axial direction to the outer peripheral portion of the extension bush 89. A portion where the notch 76 is formed is referred to as a discharge portion 79. The discharge portion 79 is formed by the bottom plate 73, the first side wall 74, and the stop portion 77, and faces the extension bush 89 in the radial direction.

The pressing portion 74 a is a plate-like portion fixed to the end portion of the stopper portion 77, and is in contact with the extended portion 23 b of the extension case 23. The pressing portion 74 a is compressed between the extension case 23 and the stopper portion 77. Since the second side wall 75 is pressed against the extension bush 89 by the elastic force of the pressing portion 74a, the position of the guide member 7 with respect to the extension case 23 is stabilized.
<Transmission operation>
The operation of the transmission 1 will be described with reference to FIG.
For example, during first speed travel, the first speed counter gear G11 and the input shaft 3 are connected by the first sync mechanism S1. Therefore, the power transmitted to the input shaft 3 is transmitted to the countershaft 4 via the first speed main gear G1 and the first speed counter gear G11. The power transmitted to the countershaft 4 is transmitted to the main shaft 8 via the counter drive gear G17 and the main drive gear G7. At this time, the main shaft 8 rotates at a rotational speed corresponding to the gear ratio between the first speed main gear G1 and the first speed counter gear G11.

When the first speed counter gear G11 rotates, the lubricating oil is scraped up by the first speed counter gear G11. Part of the lubricating oil scraped up by the first speed counter gear G <b> 11 flows into the extension case 23 through the oil gutter 9. Since the gear chamber 28 and the space in the extension case 23 communicate with each other through a gap between the bearings 51 and 56, when the level of the lubricating oil in the extension case 23 reaches the level shown in FIG. The lubricating oil returns to the gear chamber 28. That is, the level of the lubricating oil in the extension case 23 is maintained at the level shown in FIG.
In the extension case 23, the rotating member 6 rotates together with the main shaft 8. When the rotating member 6 rotates, a part of the lubricating oil is collected by the oil catcher 61 and supplied to the needle bearing through the hole 61b, the inlet oil passage 82, and the main oil passage 81.

  On the other hand, the lubricating oil in the extension case 23 is scraped up by the stirring blade 62. A portion of the lubricant oil that has been scraped flows along the inner peripheral surface 71 a of the collection member 71 toward the garter member 72. Since the collecting member 71 forms part of the side wall of the garter member 72, the lubricating oil easily flows into the garter member 72 from the inlet portion 78. Since the bottom plate 73 is inclined halfway, the lubricating oil that has flowed into the garter member 72 flows to the vicinity of the extension bush 89 and is guided radially inward by the stopper 77. Since the extension bush 89 has an oil hole 89a penetrating in the radial direction, a part of the lubricating oil flowing to the vicinity of the extension bush 89 reaches the sliding surface of the extension bush 89 through the oil hole 89a. Thereby, the sliding surfaces of the extension bush 89 and the sleeve yoke 88 are reliably lubricated, and the lubrication performance can be improved.

<Features>
The characteristics of the lubricating device L described above are summarized below.
(1)
In the lubricating device L, the lubricating oil scraped up by the rotating member 6 flows through the collecting member 71 and flows into the garter member 72. The lubricating oil flowing into the garter member 72 is guided to the extension bush 89 by the garter member 72. For this reason, the lubricating oil can be stably supplied to the extension bush 89 during normal traveling, and the lubricating performance can be improved.
(2)
Since the garter member 72 penetrates the collecting member 71, the lubricating oil collected on the inner peripheral surface 71 a of the collecting member 71 is collected in the axially rear side of the collecting member 71 (collected by the collecting member 71. Can be supplied to the extension bush 89 disposed at a position where the lubricant cannot be directly supplied.

In particular, since the bottom plate 73 is disposed close to the inner peripheral surface 71 a of the collecting member 71 at the inlet portion 78 of the garter member 72, the lubricating oil that has reached the inner peripheral surface 71 a flows into the bottom plate 73. For this reason, more lubricating oil tends to flow into the garter member 72 through the collecting member 71. That is, the collection efficiency of the lubricating oil by the collection member 71 and the garter member 72 can be increased.
(3)
Since the garter member 72 has the discharge portion 79 facing the extension bush 89, the lubricating oil can be discharged toward the extension bush 89.
(4)
Since the collection member 71 has the first portion 71b arranged so as to be immersed in the lubricating oil on the side where the rotating member 6 scoops up the lubricating oil, the lubricating oil scraped up by the rotating member 6 is the first portion. It becomes easy to flow along 71b. For this reason, it becomes easy to collect the lubricating oil that has been scraped up.

(5)
Since the garter member 72 is disposed on the side opposite to the side where the rotating member 6 scoops up the lubricating oil with respect to the rotation axis A1, the lubricating oil scattered along the rotation direction of the rotating member 6 connects the collecting member 71. Therefore, it becomes easy to flow into the garter member 72. For this reason, the collection efficiency of the lubricating oil in the guide member 7 can be improved.
(6)
Since the collection member 71 has an upper collection portion 71c that is disposed above the rotation axis A1 of the rotation member 6 and is inclined toward the extension bush 89, the upper collection portion 71c of the collection member 71 is disposed. Lubricating oil adhering to the collecting portion 71 c is likely to flow toward the extension bush 89. For this reason, more lubricating oil tends to flow into the garter member 72 through the collecting member 71. That is, the collection efficiency of the lubricating oil by the collection member 71 and the garter member 72 can be increased.

(7)
Since the collecting member 71 is a cylindrical member, the lubricating oil easily flows along the inner peripheral surface 71 a of the collecting member 71. When the lubricating oil easily flows along the inner peripheral surface 71a, the lubricating oil easily flows into the garter member 72. Thereby, the collection efficiency of the lubricating oil by the collection member 71 and the garter member 72 can be improved.
(8)
Since the collection member 71 has a shape along the inner wall of the extension case 23, the collection member 71 can be positioned with respect to the extension case 23 simply by fitting the collection member 71 into the extension case 23. .
Moreover, since the collection member 71 has a shape along the inner wall of the extension case 23, a useless space is not formed between the extension case 23 and the collection member 71, and the lubricating oil is collected. A large space can be secured. For this reason, the collection efficiency of the lubricating oil by the collection member 71 and the garter member 72 can be improved.

(9)
Since the rotating member 6 has the stirring blade 62 that scoops up the lubricating oil, the lubricating oil is easily scraped up by the rotating member 6, and the collection efficiency of the lubricating oil by the collecting member 71 and the garter member 72 is increased. Can do.
(10)
Since the collection member 71 is disposed in the extension case 23, the lubrication efficiency can be increased with a simple configuration.
(11)
Since the stirring blade 62 is integrally formed with the oil catcher 61, the lubricating oil can be efficiently scraped without increasing the number of parts.

(12)
Since the member to which the lubricating oil is supplied by the guide member 7 is the extension bush 89, the extension bush 89 that is relatively difficult to supply the lubricating oil can be reliably lubricated.
(13)
Thus, in this transmission 1, since the lubricating device L is mounted, the lubricating performance can be improved.
<Other embodiments>

The guide member 107 shown in FIG. 9 has a collecting member 171. The first end 171c and the second end 171d of the collecting member 171 are immersed in the lubricating oil. Even in this case, since the first end portion 171c arranged on the side where the rotating member 6 scoops up the lubricating oil is immersed in the lubricating oil, the lubricating oil scooped up by the rotating member 6 is collected. It becomes easy to flow to the garter member 72 along the inner peripheral surface 171a of 171. Further, the lubricating oil scattered by the rotation of the rotating member 6 can easily flow to the garter member 72 through the inner peripheral surface 171 a of the collecting member 171.
Also, the guide member 207 shown in FIG. The first end portion 271c of the collection member 271 is disposed above the rotation axis A1 and is not immersed in the lubricating oil. Even in this case, since the upper side of the rotating member 6 is covered with the collecting member 271, the lubricating oil scattered by the rotation of the rotating member 6 travels along the inner peripheral surface 271 a of the collecting member 271, and the garter member 72. It becomes easy to flow to.

Even with the configuration described above, the lubrication performance can be improved.
(C)
The device to which the lubricating device L is applied is not limited to the transmission 1. The present invention is applicable to any apparatus having a member to be lubricated.
(D)
In the above-described embodiment, the collecting member 71 is a separate member from the garter member 72, but the collecting member 71 and the garter member 72 may be integrally formed.
(E)
In the above-described embodiment, the rotating member 6 is integrally formed. However, the oil catcher 61, the stirring blade 62, the cylindrical portion 63, and the disk portion 64 that constitute the rotating member 6 may be separate members. Only a part of the part may be a separate member.
