Factors Affecting the Transmission Ratio in Torque Multiplication Characteristics

In practical applications, the selection of transmission ratio usually needs to be comprehensively considered based on specific task requirements and working environment. For example, in the automotive repair industry, for the disassembly and assembly of heavy vehicle tires, a labor saving wrench with a larger transmission ratio is usually selected to ensure sufficient torque output; while for the repair of small vehicles or precision equipment, a tool with a moderate transmission ratio may need to be selected to ensure fine control.
Factors Affecting the Selection of Transmission Ratio
Task requirements: Different fastener disassembly and assembly tasks have different torque requirements. For example, in situations where large torque is required, a labor saving wrench with a larger transmission ratio should be selected; while in situations where fine control is required, a tool with a moderate transmission ratio may be required.
Material properties: The material, strength, hardness and other properties of the fasteners will also affect the selection of the transmission ratio. For high-strength and high-hardness fasteners, a larger transmission ratio may be required to ensure sufficient torque output.
Working environment: Factors such as the size of the working environment, space limitations, and operating conditions will also affect the selection of the transmission ratio. When operating in a small space, a labor saving wrench with a compact structure and a moderate transmission ratio may need to be selected.
Cost considerations: Labor saving wrenches with higher transmission ratios tend to have higher manufacturing costs. Therefore, cost factors also need to be considered when choosing to ensure that the cost-effective product is selected while meeting the mission requirements.
