Solution Overview
Problem
Existing torque transmission devices for gate drive systems, particularly those using chains or traction devices, experience excessive wear and maintenance issues due to torque fluctuations and vibrations, leading to potential damage and increased costs.
Innovation Solution
A torque transmission device featuring a traction means guide device with elastic connecting elements that moves the slack strand away from the support device, preventing contact with the side wall and generating a restoring force to reduce oscillations and wear, thereby minimizing the impact of torque fluctuations and vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If torque is transmitted by means of a chain or traction device, then the torque transmission from the gate drive device to the gate shaft is enabled and installation variants are flexible, but the traction device vibrates due to torque fluctuations and wears out more quickly
Solution Approach 1:
A tensioning device is introduced as an intermediary component between the drive member and the gate shaft. This tensioning device includes a tensioning member that can be adjusted to apply pre-tension to the traction device, and a positioning member that maintains the tensioning member in a specific position. The tensioning device acts as a mediator to dampen torque fluctuations and reduce vibrations in the traction device, thereby reducing wear and improving durability while maintaining the flexible torque transmission capability.
2Reliability
If the traction device is tensioned to reduce vibrations, then the durability of the traction device is improved, but the complexity of the torque transmission device increases
Solution Approach 1:
The tensioning device is designed to perform multiple functions: it applies pre-tension to the traction device to reduce vibrations, provides adjustable tension control, and maintains stable operation under varying torque conditions. By integrating these functions into a single device with a tensioning member and positioning member, the design achieves multi-functionality that improves reliability without proportionally increasing complexity.
3Ease of operation
If the slack strand is allowed to move freely, then the torque transmission is smooth, but the slack strand may touch the side wall and cause damage
Solution Approach 1:
The tensioning device applies a counteracting pre-tension force to the traction device, including the slack strand. This pre-tension acts as a counterweight to the harmful effects of the slack strand moving freely and potentially contacting the side wall. By maintaining appropriate tension, the slack strand remains positioned away from the side wall while still allowing smooth torque transmission through the traction device.
