Common Member Surrounds Opening For Pulley Tooth On All Sides Patents (Class 474/235)
  • Patent number: 10479608
    Abstract: A linked disc assembly for use in continuous chain tensioning assemblies in tubular chain drag conveyors, comprising link members and alternating double ear disc members. Each disc member comprises a disc plate and an ear member transversely projecting therefrom. Each ear member consists of an arcuate leg defining a channel extending parallel to the disc plate and hingedly engaged by a link member. Each open chain link member defines a spacing gap. Each ear member arcuate leg defines a transverse notch adjacent a corresponding disc plate, the notch sized and shaped complementarily to the link member gap so as to form a sliding ramp for manual guided quick release through passage of a link member.

  • Patent number: 6595603
    Abstract: An undercarriage for a track vehicle includes an endless track having links of constant length connected end to end in the direction of travel, each link having a pair of spaced-apart guide webs and a cog which connects the webs, the cogs being of substantially identical size. The drive sprocket wheel has at least two circumferential sections with teeth having spaces therebetween for engaging cogs. The tooth pitch in each section decreases in the direction of travel from a maximum valve to a minimum value, the space between teeth having the minimum value being sufficient to accommodate one of the cogs with clearance.

  • Patent number: 5131723
    Abstract: A guide rail 4 is used for movably mounting a coal hewing machine on a chain scraper conveyor 3. The hewing machine has a guide shoe 26 guided by the guide rail 4 and a chain wheel. The conveyor 3 has a conveyor channel 2 and, on the filling side, a mounting plate 1 for the guide rail 4. The guide rail 4 defines a chain passage 19 for a chain 20. The guide rail 4 also defines, in its roof side, an engagement groove 17 for the chain wheel and, in its floor side, openings 18 for the discharge of material. The chain 20 comprises long horizontal members 22 and short vertical members 21. The guide rail 4 is of box-shaped configuration and substantially rectangular cross-section. All four sides of the guide rail 4 are engaged by the guide shoe 26. On the filling side, the guide rail 4 has an upper portion in the form of an overhead bar 13 which is screwed to the lower portion 12. The vertical members 21 of the chain 20 project into the engagement groove 17.

  • Patent number: 4993779
    Abstract: An element, adapted to be inter-engaged with a plurality of similar elements to form a rack for a mining machine haulage system, has each element comprising at one end, a looped end portion including inner and outer arcuate bearing surfaces, the inner bearing surface defining one end of an upwardly open aperture. A downwardly projecting tooth is spaced from the inner bearing surface and adapted to fill partly the aperture of the next adjacent inter-engaged element, while a correspondingly arcuate bearing surface is also provided on the tooth for abutment against the inner arcuate bearing surface of the adjacent element. Also, a transversely extending bridge is provided at the other end of the element, which bridge has transversely extending, and upwardly converging, planar faces for engagement, in use, by a tooth of a driven haulage system of an associated mining machine, dependent upon the direction of haulage.

  • Patent number: 4832187
    Abstract: A conveyor belt composed of a plurality of interconnected modules, each of identical construction and end to end mateable. Each module includes a multiplicity of elongated parallel spaced link elements terminating in first and second link ends. An intermediate section between the link ends is of grid-like structure providing a box beam across the width of the module for structural strength. This intermediate section also includes angled surfaces which define sprocket recesses located midway between the pivot axes and which are adapted to mate with corresponding sprocket teeth of an associated sprocket wheel. These intermediate sprocket recesses provide the benefit of minimizing chordal action and scrubbing between the mating surfaces of the module and sprocket.

  • Patent number: 4501447
    Abstract: A link component is adapted for interfitment with like link components to form a flexible chain free of hinge pins and cooperable with a drive sprocket. The link component has complementarily-shaped end parts (10, 11; 10' 11') whereof each is the true or inverted image of the other. Each end part comprises a transverse recess (20) located between transverse walls (21, 22) of which the longitudinally outer wall (22) is shorter than the inner wall (21). The shorter end of the outer wall (22) and the recess (20) have complementary rounded formations so that when the end part of one link (10 or 10') interengages with the end part (11 or 11') of an adjacent link, the respective outer walls (22) locate in the corresponding recess (20). Parallel side braces (12, 12') space the end parts (10, 11; 10' 11') apart through integration therewith and have external surfaces spaced laterally beyond the width of the end parts.
