If it is "one big rope loop" running between two sheaves, why not use a belt?

Discussion Overview
The discussion revolves around optimizing a motor pulley and rope combination for a project involving high-speed rotation. Participants explore various methods to prevent rope overlapping during operation, focusing on the mechanics of pulley design and the properties of the rope used.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant seeks advice on preventing rope overlap while the pulley rotates at 70 km/h, emphasizing the need for tension management.
- Another suggests using eyelet bolts for physical separation of the rope wraps, which leads to a discussion about their practicality and effectiveness.
- Concerns are raised about the torque generated by a single pulley and the potential wear issues associated with wrapping the rope multiple times.
- A participant clarifies that they are using a diving rope capable of lifting 600 kg and cannot add more pulleys due to space constraints.
- There is a proposal for using slip guides or wedges to manage the rope's position on the pulley, with discussions on materials like polypropylene and Teflon for wear resistance.
- Some participants express skepticism about the feasibility of the proposed solutions under high speed and weight conditions.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the best method to prevent rope overlap. Multiple competing views and suggestions are presented, with ongoing uncertainty about the effectiveness of the proposed solutions.
Contextual Notes
Participants note limitations regarding the speed and tension of the rope, as well as the need for further clarification on specific mechanical concepts and materials. The discussion reflects a variety of assumptions and conditions that have not been fully resolved.
