EXPERIMENTAL ASSESSMENT OF WEAR OF MODERNIZED DRIVE ROLLER CHAIN

Analysis of mechanical drives groups in agricultural machines identifies relatively narrow range of types of transmission and units. Chain transmission are mainly used as mechanical drive of assemblies and units in grain and corn harvesters designs. Transmission roller chains are used in Vector 425,...

description Analysis of mechanical drives groups in agricultural machines identifies relatively narrow range of types of transmission and units. Chain transmission are mainly used as mechanical drive of assemblies and units in grain and corn harvesters designs. Transmission roller chains are used in Vector 425, Acros 585, Torum 780 harvesters produced by combine plant «Rostselmash». The links wear during operation leads to relative elongation of middle chain pitch and reduction of reliability of the mechanical drive. To improve the drive reliability the authors proposed upgraded roller drive chain. Inserts are placed inside the hinges and form cavity for accommodating and retaining the lubricant, which guarantees lubrication of contacting surfaces of chain transmission during operation. Сomparative laboratory tests were carried out to study the relative elongation of the middle pitch of commercial and modernized chains. The authors presented experimental data and dependences of relative elongation of chains average pitch on the duration of the operation, which are approximated by second order polynomial. The speed of relative elongation of middle pitch of commercial chains is by 2.17 times more than of modernized one. The proposed modernization of the drive roller chain to perform the required set of functions without the redistribution between the elements and increase their functional load should be considered as functional redundancy to increase the reliability of the drive in the mechanical systems of agricultural purposes.
