Definitions

  • Lamellar chain (options)
  • the invention relates to mechanical engineering, to the design of drive, conveyor, traction and other plate chains, and is intended for use as flexible elements of various chain transmissions.
  • the chain chain contains hinges connecting the chain links. Two adjacent links of the chain chain are mounted with the possibility of rotation relative to each other around the axis of the hinge connecting these links.
  • the plate is a supporting element of the chain having a plane perpendicular to the axis of the hinge.
  • the thickness of the plate in a section parallel to the axis of the hinge is several times smaller than its length.
  • a chain drive with a plate chain is a device containing an asterisk mounted for rotation and a plate chain, the hinges of which are directly or through an intermediate part (for example, a roller) engaged with the teeth of the sprocket.
  • Constant friction during operation reduces the efficiency of the chain gear, leads to wear of the roller and the sleeve, which in turn leads to an extension of the chain pitch, reducing its service life and the appearance of significant noise during the operation of a chain transmission.
  • a lamellar chain is known, consisting of plates and hinges, in each hinge of which a traditional roller is replaced by a friction pair, and a roller is used as a sleeve, which also acts as an element for fastening the hinge (patent RU 2450184 F16G 13/06, 2006).
  • the closest in technical essence to the proposed solution is a lamellar chain containing plates and hinges, (patent RU 101131, according to class F16H57 / 05.2006,).
  • the hinge in the known chain contains a roller, a sleeve and a rigid element placed freely between the outer surface of the roller and the inner surface of the roller.
  • the rigid element is made with cut-outs forming cavities intended for filling with grease.
  • the known design of the plate chain allows you to increase its operational characteristics associated with the reduction of sliding friction in contacting each other parts of the chain hinge, due to the possibility of placing the lubricant directly in the hinge.
  • the main disadvantages of the known plate chain are: • the need for pre-lubricating the hinges of the plate chain; • the need to control the presence of lubricant in the hinges of the chain chain during operation;
  • the technical result solved by the invention is the creation of a plate chain, allowing:
  • the objectives of the invention are achieved by eliminating the possibility of friction in the hinge of the plate chain due to the fact that the plate chain contains plates and hinges, and its hinge contains a roller, a sleeve and an elastic element connecting the roller to the sleeve.
  • the roller In the hinge, the roller is located in the sleeve with a clearance.
  • the elastic element is located between the outer surface of the roller and the inner surface of the sleeve.
  • the elastic element is made of plastic or composite or completely made of rubber or partially made of rubber.
  • the chain contains a roller, part of the outer contour of the cross section of which is a straight line segment and the sleeve part of the inner contour of the cross section of which is a straight line segment.
  • the chain plate is made integrally with the sleeve.
  • the chain plate is made integrally with a roller.
  • the axis of rotation of the hinges of the plate chain in its free state are located on a circle.
  • the chain contains a roller.
  • the chain is made in the form of a two-row or multi-row chain.
  • the chain contains plates with holes, rollers and elastic elements, while the rollers are located inside the holes of the plates, elastic elements connect the rollers to the plates, while the elastic element is located between the outer surface of the roller and the inner surface of the plate.
  • the chain contains external plates rigidly connected to the roller and internal plates rigidly connected to the sleeve, while the sleeve is rotatably relative to the roller within the elastic twisting of the elastic element.
  • the chain is made in the form of a sleeve-roller chain containing a roller mounted rotatably between the inner plates on the sleeve.
  • the hinge of the inventive lamellar chain contains an elastic element connecting the roller to the sleeve, the mutual rotation of adjacent chain links relative to the axis of the hinge occurs solely by twisting the elastic element, while sliding friction in the roller-sleeve pair can be completely eliminated, for example, when the roller is located with clearance relative to the sleeve.
  • This technical solution eliminates the mechanical wear of the plate chain in a pair of roller-sleeve and accordingly eliminates the need for lubrication of the plate chain in the hinge.

  • the execution of the sleeve, part of the inner contour of the cross section of which is a straight line segment, allows you to reliably connect the elastic element to the inner surface of the sleeve, eliminating the rotation on the contact surface of the sleeve and the elastic element.
  • the execution of the plate chain when the axis of rotation of its hinges in the free state of the chain are located on a circle, reduces the angles of elastic twisting of the elastic elements in the hinges (when the chain enters the asterisk and when it leaves the asterisk), which in turn reduces the stresses arising in elastic hinges and increases chain durability.

  • the lamellar chain can be made in the form of a two-row or multi-row chain to increase its traction.

  • the hinge is formed only by a roller and an elastic element.
  • the plate chain may contain external plates rigidly connected to the roller and internal plates rigidly connected to the sleeve, wherein the sleeve must be rotatable relative to the roller within the elastic twisting of the elastic element and may be made in the form of a roller-roller chain containing a roller mounted between the inner plates on the sleeve with the possibility of rotation.
