Justification of Lever Arrangement Parameters for Friction-Type Traction Gear

摘要

The paper reviews the current state and application potential of the friction-type traction gear as applied for rail-guided vehicles used in mining operations. It presents a design concept of a friction-type traction gear with a lever arrangement. A kinematic diagram of the lever arrangement is provided. Optimal geometry of the key elements of the lever arrangement is defined. The analytical model of the power load on the levers is developed. A correlation between the geometry of the key lever arrangement elements and the reduction rates was established with account for operating conditions of the traction vehicle. Design recommendations for friction-type traction gear are given based on the analysis of the obtained results.
