Abstract
A silent chain includes a number of interleaved rows of link plates articulately connected together by joint pins. Each of the link plates has a pair of teeth and a pair of pin holes. The link plate further has a tubular portion protruding continuously from one surface of the link plate and defining a peripheral surface of each of the pin holes. The tubular portion has a height substantially equal to the thickness of the link plate. The tubular portion increases the contact area between the plate and the joint pin and thus suppresses wear on the joint pin. Further, by the tubular portion, the plate can retain sufficient rigidity and strength without narrowing the web width between each pin hole and the outside flank or the inside flank of the corresponding tooth. The silent chain as a whole is relatively light in weight.
Description
- 1. Field of the Invention
- This invention relates to a silent chain including a number of link plates articulately connected together by joint pins and each having a pair of teeth for meshing engagement with sprocket teeth and a pair of pin holes in which the joint pins are inserted.
- 2. Description of the Related Art
- In general, a silent chain includes articulate link rows and guide link rows alternately arranged in the longitudinal direction of the chain and articulately connected by joint pins, such as round pins or rocker joint pins, in such a manner that link plates in each articular link row and link plates in the adjacent guide link row are interleaved in a single-to-single, double-to-double, or single-to-double ply bases.
- As shown in FIGS. 4 and 5, a conventional
silent chain 20 generally compriseslink plates plates 21 form articulate link rows KL and, as shown in FIG. 6, thearticulate link plate 21 has a hollowcylindrical bush 26 formed separately from theplate 21 and fitted in each of a pair ofengagement holes 25 formed in theplate 21. A joint pin 28 (FIGS. 4 and 5) is inserted into thebush 26 so that thearticulate link plate 21 is rotatable about the axis of thejoint pin 28. Theplates 22 and theguide plates 23 together form guide link rows GL. Theguide link plate 22 has a pair of pin holes (not shown) into which thejoint pin 28 is inserted. Theguide link plate 22 may be or may not be rotatable about the axis of thejoint pin 28. In addition, theguide link plate 22 may or may not have a pair of teeth for meshing engagement with the teeth of a sprocket. - Since the
plate 21 is equipped with abush 26 fitted in theengagement hole 25, the contact area for sliding engagement between the inside surface of thepin hole 24 and the outside surface of thejoint pin 28 is relatively large and hence can suppress wear on thejoint pin 28. However, as compared to abushless plate 31 such as shown in FIG. 7, a web width W1′ between theoutside flank 27A of eachtooth 27 and theperipheral edge 25′ of theadjacent engagement hole 25 and a web width W2′ between theinside flank 27B of thesame tooth 27 and theperipheral edge 25′ of theadjacent engagement hole 25 are made relatively small provided that the diameter of thepin hole 24 is the same as that ofpin holes 32. There arises a problem that theplate 21 cannot maintain the necessary rigidity and strength. Thus, when subjected to a load during meshing engagement between theteeth 27 and the sprocket teeth, theplate 21 is liable to yield or deform due to insufficient rigidity and strength, thus making the meshing engagement unstable. - Most silent chains are formed solely by
bushless plates 31, namely, plates not quipped with a bush. As shown in FIG. 7, thebushless plate 31 can provide a relatively large web width W1, W2 between theperipheral edge 32′ of eachpin hole 32 and the outer orinner flank adjacent tooth 33. Accordingly, even if the thickness of theplate 21 is reduced, theplate 21 still able to maintain the necessary rigidity and strength. However, since the contact area for sliding movement between the inside surface of thepin hole 32 and the outside surface of thejoint pin 28 decreases with the reduction in thickness of theplate 21, a wear elongation of the silent chain is caused due to accelerated wear on thejoint pin 28. To deal with this problem, the thickness t′ of theplate 31 is increased to enlarge the contact area between thepin hole 32 and thejoint pin 28, as shown in FIG. 8. However, theplate 31 becomes heavy and increases the overall weight of the silent chain. - It is accordingly an object of the present invention to provide a silent chain which is capable of providing a relatively large contact area between pin holes in the link plates and joint pins without narrowing the web width between each pin hole and the outside or inside flank of the adjacent tooth of the link plate, to thereby suppress wear on the joint pins, prevent reduction in strength of the link plate, and limit an increase in the overall weight of the silent chain.
- To achieve the foregoing object, a silent chain according to the present invention comprises a number of interleaved rows of link plates articulately connected together by joint pins. Each of the link plates has a pair of teeth and a pair of pin holes. The link plate has a tubular portion protruding continuously from one surface of the link plate and defining a peripheral surface of each of the pin holes. The tubular portion has a height substantially equal to the thickness of the link plate.
- In each row of link plates, two link plates may arranged side by side with the respective tubular portions oriented in the same direction.
- Alternatively, in each row of link plates, two link plates may be arranged side by side with the respective tubular portions oriented in the opposite directions. The tubular portions of one of the link plates and the tubular portions of the other link plate may be directed toward each other or directed away from each other.
- The tubular projection is preferably formed by burring.
- By the tubular portion, the link plate can retain a relatively large contact area between itself and joint pins and hence is able to suppress wear on the joint pins. In addition, the web width between each pin hole and the outside flank or the inside flank of the corresponding tooth is enlarged with the result that the link plate is highly resistant to deformation or yielding when it comes in meshing engagement with the sprocket teeth.
- The above and other objects, features and advantages of the present invention will become manifest to those versed in the art upon making reference to the following description and accompanying sheets of drawings in which certain preferred structural embodiments incorporating the principle of the invention are shown by way of illustrative example.
- FIG. 1 is a plan view of a link plate of a silent chain according to an embodiment of the present invention;
- FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
- FIGS.3A-3D are cross-sectional views illustrative of variations in arrangement of the link plate;
- FIG. 4 is a plan view, with parts in cross section, of a conventional silent chain;
- FIG. 5 is a front elevational view, with parts cutaway for clarity, of the conventional silent chain;
- FIG. 6 is a plan view of a conventional link plate;
- FIG. 7 is a plan view of a different conventional link plate; and
- FIG. 8 is a cross-sectional view of the conventional link plate shown in FIG. 7.
- The following description is merely exemplary in nature and is in no way intended to limit the invention or its application or use.
- FIG. 1 shows a
link plate 1 according to an embodiment of the present invention. Thelink plate 1 is used in articulate link rows and guide link rows of a silent chain in the same manner as shown in FIGS. 4 and 5. Thelink plate 1 has a pair ofpin holes teeth teeth 3 each have anoutside flank 3A and an insideflank 3B. Theoutside flank 3A or theinside flank 3B forms an engagement surface when thecorresponding tooth 3 comes in meshing engagement with teeth on a sprocket (not shown). - As shown in FIG. 2, the
pin holes 2 formed in thelink plate 1 each have aperipheral surface 2′ formed or defined by atubular portion 2A protruding continuously from one surface of thelink plate 1. The tubular portion 2 a is formed as an integral part of thelink plate 1. The height h of thetubular portion 2A is determined in option. It is preferable, however, that the height h of thetubular portion 2A is substantially equal to the thickness t of thelink plate 1. - The
tubular portion 2A is formed by burring a drilled portion of thelink plate 1. In the illustrated embodiment, before the burring process is carried out, thelink plate 1 is drilled to form a pair of blank holes (not shown) at a position corresponding to the position ofpin holes 2 to be produced. The drilled blank holes are smaller in diameter than thepin holes 2. Then, thelink plate 1 is supported on a die such that the drilled blank holes are in register with circular cavities formed in the die, the cavities having an inside diameter substantially equal to the outside diameter of atubular portion 2A to be formed. Subsequently, punches having an outside diameter substantially equal to the inside diameter of thepin hole 2 are forced into the drilled blank holes whereby the drilled blank holes are enlarged and, at the same time, a portion of the plate extending around each drilled blank hole is shaped into a circular tube. By using the burring process, thetubular portion 2A defining a peripheral surface of thepin hole 2 can easily be produced. - In the
link plate 1 thus formed, as shown in FIG. 1, a web width W1 between theperipheral surface 2′ of eachpin hole 2 and theoutside flank 3A of theadjacent tooth 3 and a web width W2 between theperipheral surface 2′ of thesame pin hole 2 and theinside flank 3B of theadjacent tooth 3 are equal to the corresponding web widths W1 and W2, respectively, of the conventionalbushless link plate 31 shown in FIG. 7. This means that the web widths W1 and W2 of thelink plate 1 are greater than the corresponding web widths W1′ and W2′, respectively, of the conventionalbushed link plate 21 shown in FIG. 6. Thelink plate 1 can, therefore, maintain the necessary rigidity and strength even if the thickness is reduced. Further, by virtue of theintegral tubular portion 2A, thelink plate 1 can provide a relatively large contact for sliding movement between thepin hole 2 and a joint pin (not shown but identical to the one 28 shown in FIG. 4) that is comparable to the contact area provided by thebushed link plate 21 shown in FIG. 6. With this large contact area, wear on the joint pin can be suppressed. - To form a silent chain, a large number of
such link plates 1 are articulately connected together by joint pins such as round pins or rocker joint pins (see, thejoint pins 28 shown in FIG. 4) in such a manner that thelink plates 1 are interleaved on a single-to-single ply basis, a double-to-double ply basis, or a single-to-double ply basis. In this case, the silent chain is formed solely by thelink plates 1. - As an alternative, the
link plates 1 may be assembled in double ply in the same manner as thearticulate link plates 21 of the conventionalsilent chain 20 shown in FIG. 4. In this instance, the link plates 22 (FIG. 4) forming the guide link rows GL may be either used in combination with thelink plates 1 or replaced by thelink plates 1. - FIGS.3A-3D show various arrangements of the
link plate 1 available in assembling a silent chain. In FIG. 3A, twolink plates 1 are arranged side by side in each row of link plates with the respectivetubular portions 2A being directed in opposite directions. In this arrangement, thetubular portions 2A of onelink plate 1 and thetubular portions 2A of theother link plate 1 are directed away from each other. In FIG. 3B, twolink plates 1 are arranged side by side in each row of link plates with the respectivetubular portions 2A being directed in the same direction. The arrangement shown in FIG. 3C is similar to the arrangement shown in FIG. 3A but differs therefrom in that thetubular portions 2A of onelink plates 1 and the tubular portions of theother link plate 1 are directed toward each other. The arrangement shown in FIG. 3D is substantially the same as the arrangement of FIG. 3B with the exception that thetubular portions 2A are oriented in opposite relation to thetubular portions 2A of theplates 1 shown in FIG. 3B. In making a silent chain, thelink plates 1 may be arranged in single play or in random orientation. - By virtue of the
link plate 1 having antubular portion 2A around eachpin hole 2, the silent chain formed bysuch link plates 1 provides a relatively large contact area for sliding movement between the pin holes 2 ane joint pins and thus reduces wear on the joint pins. Further, thelink plate 1 can maintain sufficient rigidity and strength which are comparable to those of the conventional bushless link plate without causing reduction in the web width W1 or W2 between eachpin hole 2 and the outside or inside flanks 3A, 3B of the corresponding tooth. When meshing with the sprocket teeth, thelink plate 1 does not cause deformation and insures stable meshing operation. In addition, the thickness of theplate 1 can be reduced with the result that the silent chain as a whole is relatively light in weight. In a roller chain which falls in a different category from the silent chain, there is a plate having a tubular portion formed by burring. The tubular portion of the roller chain has a role to support or bear a roller adapted to mesh with the teeth on a sprocket and to retain a contact area between itself and a joint pin. In the silent chain of the present invention, however, the burring process achieved in forming a tubular portion on the plate is used for the purpose of preventing reduction in strength of a toothed portion of the link plate adapted to mesh with the sprocket teeth, providing a large contact area between the plate and the joint pins, and decreasing the weight of the link plate. - As described above, the link plate forming a silent chain of the present invention has an integral tubular portion protruding continuously from one surface of the link plate and defining a peripheral surface of each of a pair of pin holes. The tubular portion preferably has a height substantially equal to the thickness of the plate. By the tubular portion, the plate has an enlarged contact area for sliding engagement between itself and joint pins inserted into the pin holes and can suppress wear on the joint pins. Further, the link plate having such tubular portions retains sufficient rigidity and strength without reducing the web width between each pin hole and the outside flank or the inside flank of the corresponding tooth. Thus, the plate does not undergo deformation or yielding when it comes into meshing engagement with the sprocket teeth. The silent chain constituted by the link plates is relatively light in weight.
- Obviously, various minor changes and modifications of the present invention are possible in the light of the above teaching. It is therefore to be understood that within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described.
