Definitions

  • the invention deals with articulated chains with more lines covering the sphere of bushing as well as roller chains.
  • the presented technological design deals both with chains made of metal and chains produced of non-metal materials.
  • Another disadvantage is that the intermediate plate must be produced as a separate part of the chain as it is not the same as the external plates.
  • the intermediate plates are different from the external plates due to their bigger central hole made for the purpose of easier assembly.
  • the surface of the pins is subject to increased wear due to vibrations just at the point it touches the intermediate plates.
  • the weight disadvantage of the existing multi-line articulated chains with the method of using lightweight materials is inconvenient for price reasons as well as due to reduced load-bearing capacities of chains modified this way.
  • Solving the disadvantages consisting in the tendency to vibrations by using dampening inserts or materials with increased internal dampening of vibrations is not realistic in most cases for the reason of the price or strength.
  • the external plates and/or pins of the external links may be dimensioned a little more strongly while the decisive advantages of the version of the multi-line articulated chain in accordance with the presented technological solution remain preserved in such a situation.
  • the internal link contains just one type of plates and the external plates can have the same dimensions as the internal plates in many cases, just the diameter of the pin hole in the external plate is smaller.
  • Fig. 1 shows the ground plan of an assembled multi-line articulated chain of the bushing type with a partial section of an internal link
  • Fig. 2 shows a ground plan again, this time of a separate internal link and also with a partial section of its bushing
  • Fig. 3 shows the ground plan with a partial section of an internal link of a multi-line articulated chain of the roller type
  • Fig. 4 shows the ground plan with a partial section of the bushing and roller of an internal link of a roller multi-line chain.
  • the articulated multi-line chain of the bushing type consists of internal links 1 formed with internal plates H, in this case there are three with pressed-on bushings 12, and further of external links 2 represented with two external plates 2 ⁇ _ with pressed-on pins 22. These pins 22 go through cavities in the bushings 2 creating the connection of the internal links 1 and the external links 2.
  • the multi-line articulated chain of the roller type is analogous to the previous example, but there is a difference that on the bushings 12 of the internal links i there are freely positioned rollers 3 between the internal plates IJ . .
  • the articulated chains are made of common structural steel.
  • the equ pment based on the presented invention is used in the same way as the exi sting articulated chains of the bushing and roller type, but mainly in appl cations where it is desirable to save space in the lateral direction. Its advantage of a cheaper construction consisting of a lower number of parts and the narrower range of types of plates forming the chain will be used.
