Description

The present invention relates to lubricating equipment for chain drive, preferably relates to a lubricating equipment for chain drive of a motorcycle or the like.

  Conventionally, chain drives require regular lubrication with a lubricant. As the lubricant, a highly viscous liquid lubricant or a solid lubricant can be used. Liquid lubricants with high viscosity have a drawback that impurities such as dust and sand are likely to adhere to the chain drive due to the lubricating film formed by the lubricant. Since these impurities bring about a polishing action on the sliding surface that comes into contact with the chain drive, wear of the chain drive is promoted. In particular, chain drives used in harsh environments such as motorcycle chain drives and bicycle and similar chain drives tend to have relatively short service life and short maintenance intervals. .

Conventionally, an apparatus for applying a solid lubricant to a chain drive is known. The solid lubricant is pressed against a predetermined part of the chain drive. When a solid lubricant is used for the chain drive, no lubricant film is formed, and therefore dust from the surroundings can be prevented. The solid lubricant is applied to a predetermined part of the chain drive by a brush. However, in this case, since the relative speed of the chain or the relative speed of the sprocket wheel meshed with the chain is high, there is a problem that the lubricant cannot be reliably applied. Furthermore, if the lubrication device is operated under a condition in which a preload is applied to a predetermined part of the chain drive, vibration and friction are generated, which adversely affects the running characteristics of the chain drive. In addition, the lubricant is used up relatively quickly by the contact pressure on the chain drive that occurs in such a connection. Moreover, most of the known lubrication devices are designed so that they cannot be properly placed in the chain drive. In particular, in the case of a motorcycle chain drive, the chain drive is usually guided around the axis of the swing arm of the rear wheel so that the swing arm is placed in the part surrounded by the chain of the chain drive, There is almost no space for placing lubrication devices. Apart from this, the swing arm is configured such that the output sprocket wheel can pivot about the axis of the swing arm. As a result, the position of the chain is constantly changing relative to the frame or drive sprocket wheel where the position is fixed. Therefore, it is almost impossible to fix and mount the lubrication device without operating the chain. In any case, the chain is adversely affected by the load being continuously changed by the lubricating device.

An object of the present invention is to provide not affect the running properties of the substantially chain drive, lubrication equipment that the chain drive can be easily and reliably lubricated.

An object of the present invention, the lubricating device having the features of claim 1, it is possible to resolve.

The lubrication device for lubricating a chain drive according to the present invention, preferably a motorcycle or the like, of a motorcycle or the like forms a contact area where the chain of the chain drive is supported on the long side and the chain contacts. A rail portion is provided, and at least a part of the contact area is constituted by a solid lubricant applied to the chain.

The rail part has a relatively long contact area in contact with the chain compared to a lubrication device with only a part in contact with the chain, so even if the relative speed is high, the operation of the chain is substantially Unaffected. Furthermore, the rail part is preferably contactable simultaneously with a plurality of chain links so that the chain operates more quietly. In this case, since the chain is stabilized by the rail portion, it is advantageous even when the load changes. By increasing the contact area, the lubricant can be reliably applied to the chain with low friction, so that the relative speed of the chain can be increased.

When the rail part has at least one guide part, the chain is surely guided, so that the chain can be run straight with low vibration by this lubricating device.

  The said guide part can also be formed in plate shape. Thereby, a guide part can be formed easily. For example, a rail part can be comprised with plate-shaped guide part itself.

  In particular, it is preferable that the guide portion is configured to form a contact area in the guide portion and to be able to contact the bush of the chain. This allows the solid lubricant to be applied directly in contact with the worn parts and components in the chain drive. Furthermore, the width of the guide can be designed so that the inner link plate of the chain contacts the guide. As a result, the inner link plate can be lubricated and the chain can be reliably guided to the side.

  Furthermore, the inclined surface which inclines with respect to the longitudinal direction of a rail part can be formed in a guide part. Thereby, the chain is guided to the rail portion so that the traveling direction becomes an acute angle. For this reason, the chain and the rail portion can be brought into contact with little or substantially no influence on the running characteristics of the chain.

  A pair of outer guide portions configured to be accommodated in the rail portion with the outer link plate of the chain interposed therebetween may be further provided. The pair of outer guide portions can more reliably guide the chain within the rail portion. Furthermore, it is possible to prevent the chain from jumping out of the rail portion, for example, due to a change in load, and the vibration or shaking of the chain in the lateral direction.

  Furthermore, the rail part can be provided with at least one connection part for connecting the guide parts to each other. For example, the connecting portion can constitute the bottom portion of the rail portion. The connecting portion supports the link plate of the chain so as to restrict the chain from vibrating in a direction perpendicular to the traveling direction when the solid lubricant is consumed.

  The rail part may be composed of a plurality of parts. The rail part can be composed of various parts composed of various materials. For example, a part of the rail part that is not related to the supply of the lubricant can be made of a plastic material having excellent sliding characteristics. In this way, worn parts and used up solid lubricant can be replaced independently of other parts remaining on the rail.

  It is preferable that the rail portion is laminated with the guide portion together with the connecting portion because the rail portion can be easily manufactured. The guide part and the connecting part are each composed of a flat part, and a rail part is formed by combining these in a layered manner.

  When the rail portion is provided with at least one other guide portion constituting the cover portion, the entire circumference of the chain can be surrounded by the rail portion, and the guide of the chain can be further ensured. Thereby, the open part of a rail part can be covered with a cover part so that the whole periphery which crosses the advancing direction in a chain may be partially enclosed by a rail part. As a result, it is possible to completely prevent the chain from moving in a direction perpendicular to the traveling direction of the chain.

  The rail portion can be integrally formed. Thereby, a rail part can be formed so that it may become cost effective with a simple shape.

Furthermore, in order to improve the running characteristics of the chain, the contact area can include at least two contact area portions having different shapes in the longitudinal direction of the rail portion. By combining the contact areas in this way, it is possible to consider the penetration of the chain into the lubrication device and the wear performance of the contact areas.

  At least a part of the rail part can be constituted by a flat contact region extending in the longitudinal direction of the rail part. The flat contact area allows the chain to be guided more straight.

  Furthermore, at least a part of the rail portion can be formed of a contact region that is formed in a convex shape and extends in the longitudinal direction of the rail portion. Thereby, the chain is guided by the contact area or is guided away from the contact area at an acute angle. Therefore, the chain can be reliably brought into contact with the contact area.

  In order to properly arrange the rail portion in the chain drive, at least a part of the rail portion may be formed in a shape in which a wedge-shaped tip is cut off. The chain drive is usually provided with sprockets of various pitch circle diameters, but the angle between the fixed surface of the sprocket wheel shaft and the chain can be adjusted by this rail portion.

  The rail portion may be arranged to support the tension side of the chain. The tension side is always tensioned in the direction of travel of the chain in the same way, except when the load is changed, compared to the loose side, so the rail contact area is in the irregular lateral direction of the chain. It is hardly affected by the movement of the chain or the lateral force of the chain. Therefore, the contact area of the rail portion is hardly worn away.

  On the other hand, it is also possible to arrange the rail portion so as to support the slack side of the chain. For example, while the vehicle is being driven off-road, the impact of the chain drive acts on the loose side, and the load changes due to the chain swinging or knocking. On the other hand, if the rail portion is provided on the loose side, the swinging and knocking of the chain can be limited or reduced.

In order to accurately position the lubrication device with respect to the chain, the lubrication device can be further provided with a holding portion. With this holding portion, the rail portion can be positioned with respect to the chain and the rail portion can be held. Furthermore, when the rail part is composed of a plurality of parts, the holding part can be configured such that the holding part fixes the components of the rail part to each other.

  Furthermore, the holding unit can be configured to be connectable to a swing arm of a motorcycle. Thereby, for example, the rail portion can be held relatively close to the rotation axis of the swing arm by the holding portion. As a result, on the swing arm that operates with the chain, it is possible to guide the rail portion so as to be in parallel with the traveling direction of the chain. Furthermore, the holding part can offset the direction of the chain in all directions with respect to the shape of the swing arm.

  In this connection, it is preferable that the rail portion is configured so that the height relative to the holding portion can be changed by an adjustment mechanism. The position of the rail portion with respect to the chain is adjusted by an adjusting mechanism such as a spring, a screw, or a wedge. The wear of the rail part can be adjusted by changing the position of the rail part. It can also be changed to an effective contact area or contact force by an appropriate method.

  It is preferable that the holding unit is configured so that at least the solid lubricant can be replaced. Thereby, the worn solid lubricant can be easily replaced. The solid lubricant holder is preferably held so that it can be replaced without using a tool.

A motorcycle driven by a chain is preferably provided with a swing arm guard arranged to cover one side of the swing arm facing the chain near the drive sprocket wheel. The swing arm guard is for preventing the chain and the swing arm from coming into direct contact while the load is changing or while the swing arm is operating. Thereby, it can prevent that a chain and a swing arm contact and are damaged. In this range, the lubricating device is preferably configured to be usable as a swing arm guard for a motorcycle. Thereby, another swing arm guard can be omitted.

The lubricating device can be configured to be used as a chain guide for a motorcycle. In particular, the chain guide is preferably located near the output sprocket wheel. As a result, it is possible to prevent a problem that the chain knocks in the loose side region near the output sprocket wheel. Here, the chain guide can apply the lubricant to the chain simultaneously with guiding the chain. A conventional chain guide can be separately provided with a rail portion having a chain guiding function.

  When the solid lubricant is composed mainly of graphite, it is particularly advantageous from the viewpoint of lubrication characteristics and wear resistance, which are conditions for lubricating the chain.

Even when a part of the solid lubricant is composed of graphite and the remaining part is composed of another mixture, desired lubrication characteristics and wear resistance can be obtained. Thereby, other characteristics can be added to the solid lubricant. Regardless of whether the graphite material is used exclusively or partially to form a solid lubricant, for example, molybdenum sulfide, tungsten disulfide, polytetrafluoroethylene, tricalcium phosphate, hydroxide Other materials such as calcium, polyethylene, polyamide, etc. can also be used. In addition to this, it is conceivable to use soft metals such as lead, copper, and antimony. The composition of the solid lubricant based on graphite is particularly preferably a mixture with Teflon (registered trademark) , copper, lead, antimony, molybdenum disulfide and the like.

  Apart from selecting a suitable additive material, the solid lubricant may contain an anti-wear additive such as polytetrafluoroethylene. Thereby, it can suppress that a solid lubricant wears excessively.

  The solid lubricant preferably contains a corrosion inhibitor. Thereby, the corrosion resistance of the chain drive, particularly the corrosion resistance of the portion in contact with the solid lubricant is improved.

  In the solid lubricant, in order to intermittently use materials having different compositions, the solid lubricant preferably has a layer structure composed of a plurality of layers having different compositions. Here, it is conceivable to add a substance capable of removing the formed corrosion layer to the solid lubricant so as to be used at regular intervals in the chain drive.

In a method for lubricating a chain drive according to the present invention using a lubrication device having a rail portion, particularly in a chain drive lubrication method for a motorcycle or the like, the lubrication device forms a contact area for the chain drive on the long side. A rail portion is provided, and at least a part of the contact area is constituted by a solid lubricant applied to the chain. Therefore, the rail portion is arranged so that the contact region including the solid lubricant applied to the chain supports the chain such that the longitudinal direction of the contact region is along the chain of the chain drive.

  Further advantageous embodiments of the method can be taken from the features of the subclaims associated with the device of claim 1.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 21 is a side view of a rail portion according to the tenth embodiment.

  FIG. 1 shows a schematic diagram of a chain drive 10 of a motorcycle. The chain drive 10 includes a drive sprocket wheel 11, an output sprocket wheel 12, and a chain 13 (details are omitted). The direction of travel of the chain 13 is illustrated by the arrow 14. The drive sprocket wheel 11 is attached to a motorcycle drive device (details omitted) so that the position is fixed. The output sprocket wheel 12 is attached to a swing arm 15 which is shown only schematically. The output sprocket wheel 12 can turn around the swing arm shaft 16. The swing arm 15 moves in the direction of the arrow 17 together with the output sprocket wheel 12. Since the swing arm shaft 16 is disposed relatively close to the shaft 18 of the drive sprocket wheel 11, the chain 13 operates on the swing arm 15 that operates along the arrow 17 and substantially parallel to the swing arm 15.

As shown in FIGS. 1 and 2, the swing arm 15 is formed with two box portions 19 and 20. A rear wheel (not shown) of the motorcycle is provided between the box portions 19 and 20 together with the output sprocket wheel 12. Further, the box portion 20 is disposed substantially inside the chain 13. In the vicinity of the swing arm shaft 16, the drive sprocket wheel 11 is preferably miniaturized so that the box portion 20 can be brought close to the chain 13. A lubricating device 21 is mounted on the box portion 20 in the vicinity of the swing arm shaft 16. The chain 13 proceeds so as to pass through the lubricating device 21. Thereby, the lubricating device 21 supports the tension side 22 of the chain 13 regardless of the operation of the swing arm 15. Furthermore, the lubricating device 21 is formed so as to be arranged along the plane 23 of the chain drive 10 whose details are not shown. The tension side 22 of the chain 13 is tensioned so as to be substantially straight with respect to the loose side 24 of the chain 13 except when the load varies. Thereby, the chain 13 contacts the lubrication apparatus 21 reliably.

3 and 4 show the lubricating device 21 shown in FIGS. 1 and 2 in detail. The lubricating device 21 is substantially constituted by a holding portion 25 and a rail portion 26. In this embodiment, the rail portion 26 is made of a solid lubricant that wears, preferably a graphite material, and forms a holding region 27 for receiving and guiding the chain 13. The holding part 25 is made of light metal and accommodates the rail part 26 between the two leg parts 28 and 29. Furthermore, the holding part 25 has a leg part 30. The holding part 25 is designed so that the rail part 26 can be positioned relative to the chain 13 so that the plane 23 of the chain drive 10 and the axis of symmetry 31 of the rail part 26 coincide.

  In order to fix the holding part 25 to the box part 20, through holes 32 and 33 are formed in the leg part 30. Thereby, it becomes possible to fix the holding | maintenance part 25 and the box part 20 with a screw | thread.

  FIG. 5 is a side view of the rail portion 34, in which a cross section of the chain 35 is also illustrated. The rail portion 34 is integrally formed and includes two outer guide portions 36 and 37 and a main guide portion 38. These are connected to each other via connection portions 39 and 40. The main guide 38 is lower than the outer guides 36 and 37 with respect to height. The connecting portions 39 and 40 are provided such that a slot 41 is formed between the main guide portion 38 and the outer guide portion 36, and a slot 42 is formed between the main guide portion 38 and the outer guide portion 37, respectively. As a result, a holding region 43 for the chain 35 is formed. Further, the outer guide portions 36 and 37 have a function of guiding the chain 35 in the holding region 43. The chain 35 includes a large number of chain link portions 44 connected to each other. Each chain link portion 44 includes a pair of inner link plates 45, a pair of outer link plates 46, an O-ring 47, a bush 48, and a pin 49. Since the bushing 48 and the inner link plate 46 are wound around a chain drive sprocket wheel (not shown), the components of these chains require lubrication. For this purpose, the main guide portion 38 is formed with a contact region 50 extending in the same direction as the rail portion 34. The contact region 50 is configured such that the solid lubricant is worn / separated from the main guide portion 38 when the chain 35 passes over the rail portion 34. Thereby, the lubricant is applied to the chain. As the solid lubricant further wears and the inner link plate 45 and the outer link plate 46 are supported by the connecting portions 39 and 40, the main guide portion 38 is used up.

  FIG. 6 shows a rail portion 51 according to the second embodiment. The rail portion 51 is composed of a plurality of parts. The rail portion 51 includes an outer guide member 52, a connection member 53, a main guide member 54, and a U-shaped member 55. The outer guide member 52, the connection member 53, and the main guide member 54 are accommodated between the leg portions 56, 56 of the U-shaped member 55 so as to be fixed to each other and in a laminated state 57. When the main guide member 54 is used up, only the new main guide portion 54 can be replaced without having to replace the entire rail portion 51.

  FIG. 7 shows a rail portion 58 according to the third embodiment. The rail part 58 includes a lower part 59 for applying a lubricant to a chain (not shown) and an upper part 60 formed as a cover part. The lower part 59 is formed like the rail portion illustrated in FIG. 5 and is covered by the upper part 60 or connected to the upper part 60. The upper part 60 is formed in the same shape as the lower part 59. Accordingly, the chain can be accommodated in the holding region 61 formed between the lower part 59 and the upper part 60.

  FIG. 8 and FIG. 9 show a rail portion 62 that constitutes a rectangular body 68 having a substantially rectangular shape. The contact region 63 extends in the longitudinal direction of the rail portion 62 so as to be substantially parallel to the outer guides 64 and 65 as well as the connection portion 66 of the rail portion 62.

  10 and 11 show a rail portion 67 formed in a wedge shape with a part cut away. The contact surface 70 is divided into two contact area portions 71 and 72. The contact region portion 71 is formed flat along the longitudinal direction of the rail portion 67, while the contact region portion 72 formed continuously with the contact region portion 71 is formed in a bulging convex shape. . In the direction (longitudinal direction) in which the contact surface extends, it is preferable that the two contact region portions 71 and 72 have different shapes. As a result, the running characteristics of the chain can be improved, and the lubrication characteristics and guide characteristics of the rail portion 67 can be positively affected.

  12 and 13 show the rail portion 73 having a simplified shape. The rail part 73 is comprised by the guide part 74 formed in plate shape. The chain (not shown) simply runs on the contact area 75 of the guide portion 74.

  14 and 15 show a rail portion 76 that is substantially the same as the rail portion shown in FIGS. 10 and 11. However, unlike the rail portion shown in FIGS. 10 and 11, the rail portion 76 shown in FIGS. 14 and 15 has a flat contact region 77 inclined so as to form an acute angle with respect to the connection surface 78. The degree of wear of the guide portion 79 differs in the longitudinal direction of the guide portion 79. For this reason, the height of the contact region 77 with respect to the contact surface 78 is changed in the longitudinal direction of the guide portion 79 so as to take this into consideration.

  The rail portion 80 shown in FIGS. 16 and 17 is different from the rail portion shown in FIGS. 14 and 15 in that the contact region 81 and the contact surface 82 are each formed in an arc shape in the longitudinal direction. The diameter R1 of the arc of the contact area 81 and the diameter R2 of the contact surface 82 are different from each other.

  18 and 19 show a rail portion 83 that can be changed in position relative to a chain (not shown). The rail portion 83 has screw holes 85 and 86 located on the symmetry plane 84. Screws (not shown) are inserted into the screw holes 85 and 86. The screw can be used to adjust the rail portion 83 or to adjust the position of the rail portion 83 relative to the chain when the rail portion 83 is worn.

  20 and 21 show a rail portion 87 having an adjusting mechanism constituting the wedge portion 88. FIG. The height of the rail portion 87 relative to the chain (not shown) can be changed by moving the wedge portion 88 in the longitudinal direction of the rail portion 87 in a right angle groove 89 formed on the outer side 90 of the rail portion 87.

As described above, the present invention is particularly useful with the lubricating equipment for chain drive of a motorcycle or the like.
