A New Design For the Guide Plate in Silent Chains Characterized with External Meshing Mechanism

摘要

In this paper, a new-style guide plate, which is applied to silent (teething) driving-chain with external meshing mechanism and rocker-pin jointing, was designed structurally by simulating and analyzing its working stress. The materials in some region where the working stress is low are removed. The new guide board has many advantages in comparison with the conventional one, such as lighter weight, better elastic behavior and lower energy-consumption, while the strength of the new item is still the same as the conventional. Hence, the designed guide plate may be adapted better to high-speed chains used in automobile engine.
