Definitions

  • This invention relates to a sprocket for a chain and sprocket assembly.
  • the invention has been devised particularly, although not necessarily solely, for use in relation to a chain and sprocket assembly in an endless track for a tracked vehicle, such as for example a bulldozer, grader or shovel.
  • Tracked vehicles such as bulldozers, graders and shovels are often required to operate in environments containing abrasive materials such as sand, dust, dirt and mud.
  • abrasive material can accumulate in the chain sprocket at the interface between the sprocket and the portion of the chain engaging the sprocket. This can lead to premature wear of that part of the chain which engages the sprocket, as well as the part of the sprocket which is engaged by the chain. Further, the accumulated material can cause the chain to dislodge from the sprocket.
  • a sprocket of a tracked vehicle said vehicle having at least one endless track adapted to support the vehicle from the ground and to cause movement of the vehicle over the ground, said sprocket engaging the chain to support the vehicle relative to the chain, said sprocket being formed around its periphery with a plurality of teeth with tooth spaces being defined between the teeth, said tooth spaces being intended in use to engage substantially cylindrical surfaces provided by pin assemblies of the chain and which are located at spaced intervals along the chain, each tooth space defining an engagement face which is intended to engage the cylindrical surfaces, the engagement faces extending between the opposed side faces of the sprocket and each having a configuration which is complementary to the portion of the cylindrical surfaces to be engaged thereby, each engagement faces having at least one transverse channel extending across the engagement face from an inner end located at an intermediate position across the engagement face and opening at its outer end to at least one side of the sprocket.
  • the cross-sectional area of the channel increases in the direction towards said outer end.
  • the increase in cross-sectional area is provided by an increase in the depth and/or width of the channel.
  • the channel extends the full width of the socket so as to open onto both sides of the sprocket.
  • the channel has its minimum cross-sectional area at a position located substantially centrally across the width of the sprocket.
  • each tooth space is provided with only one channel
  • the channel is located at the base of the tooth space.
  • a chain and sprocket assembly of a tracked vehicle said vehicle having at least one endless track adapted to support the vehicle from the ground and to cause movement of the vehicle over the ground, said sprocket engaging the chain to support the vehicle relative to the chain, wherein the sprocket comprises a toothed sprocket as described above.
  • the endless track for a tracked vehicle the endless track comprising a track chain in engagement with a toothed sprocket, the toothed sprocket being of the form as described above.
  • the first embodiment of the invention as shown in the drawings is directed to a toothed sprocket 10 adapted for engagement with an endless track chain (not shown) of a tracked vehicle such as a bulldozer, grader or shovel.
  • the toothed sprocket 10 comprises a rim 12 having two opposed sides 13 and a plurality of teeth 14.
  • a tooth space 16 exists between each two adjacent teeth 14.
  • Each tooth space 16 is defined by an arcuate face 18 provided on the rim 12, the arcuate face defining not only the tooth space 16 but also portions of the two adjacent teeth 16.
  • the arcuate face 18 is intended to engage the pin assembly of the track chain.
  • Such pin assemblies have an outer cylindrical surface. Accordingly the arcuate face has a complementary profile to the cylindrical surface such that it will closely engage the cylindrical surface for its full width.
  • a channel 20 is provided at the base of each arcuate face 18.
  • the channel 20 comprises two channel sections 21, 22 each extending to an opening onto a respective one of the sides 13 of the sprocket 10.
  • each channel section 21 and 22 has an inner end 23, and an outer end 24 which opens to the respective side 13.
  • the inner ends 23 of the two channel sections 21 , 22 merge at crest 25 which is located centrally along the channel.
  • the cross-sectional area of each channel section 21 , 22 increases in the direction from the inner end 23 to the outer end 24. In the case of the first embodiment shown, the increase in cross-sectional area is achieved by an increasing width and an increasing depth in the direction from the inner end 23 to the outer end 24.
  • the chain comprises a roller chain having roller elements adapted to locate in the tooth spaces 16, in which case the abrasive matter is discharged as the roller elements engage in the tooth spaces.
  • each channel section there is a higher pressure zone created within the accumulated material at the inner end of each channel section and a lower pressure zone created at the outer end, the pressure difference inducing flow of the accumulated material outwardly. In this way, accumulating abrasive material is expelled from the sprocket.
  • the transition between the inner ends 23 of the channel section may be smooth rather than being defined by the crest 25 of the first embodiment.
  • the inner ends of the two channel sections 21, 22 are separated from each other by a portion of the arcuate face to provide a landing therebetween.
  • the increase in cross-sectional area is achieved principally by an increasing width in the direction from the inner end 23 to the outer end 24.
  • the increase in cross-sectional area is achieved principally by an increasing depth in the direction from the inner end 23 to the outer end 24
  • the present invention provides a simple yet highly effective arrangement for displacing abrasive material which might otherwise accumulate in a sprocket wheel to cause premature wear and possibly also dislodgement of the chain in driving engagement with the sprocket.

Abstract

La présente invention concerne un barbotin (10) pour véhicule chenillé, ledit véhicule possédant au moins une chenille sans fin adaptée pour isoler le véhicule du sol et en permettre le déplacement sur ce dernier. Le barbotin vient en prise avec la chaîne afin de supporter le véhicule par rapport à cette dernière. Ledit barbotin possède, sur sa périphérie, une pluralité de dents (14), entre lesquelles sont définis des entredents (16) destinés à venir en prise avec des surfaces sensiblement cylindriques présentées par des ensembles axes de la chaîne et séparées par des intervalles le long de cette dernière. Chaque entredent définit une face d'engrènement exact (18) qui est conçue pour venir en prise avec lesdites surfaces cylindriques. Les faces d'engrènement s'étendent entre les faces latérales opposées du barbotin, chacune desdites faces d'engrènement possédant une configuration complémentaire à la partie des surfaces cylindriques avec lesquelles elles viennent en prise, chaque face d'engrènement possédant au moins un canal transversal (20) s'étendant à travers la face d'engrènement à partir d'une extrémité interne (23) située à une position intermédiaire dans la face d'engrènement et donnant, au niveau de son extrémité externe (24), sur au moins un côté du barbotin.
