Circumferential Lever Booster for Torque Gain Without Speed Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical transmission power equipment faces challenges in increasing torque without reducing rotation speed, and achieving both high torque and speed simultaneously is difficult, especially with reducers that require series connections which further reduce speed.
Innovation Solution
The circumferential lever booster employs a mechanism with an acting force input mechanism, a circumferentially distributed lever arm group, and a boost output mechanism, utilizing eccentric wheels and lever arms to transmit force efficiently, allowing for both torque multiplication and self-locking functions while maintaining speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a reducer is used to increase output torque, then torque multiplication is achieved, but rotation speed is dramatically reduced
Solution Approach 1:
The transmission system is segmented into multiple independent circumferential lever boosters that can be connected in parallel. Each booster maintains its own speed while contributing to torque multiplication, allowing the system to achieve high torque output without sacrificing rotation speed. The parallel configuration enables torque addition while preserving the speed characteristics of individual units.
Solution Approach 2:
The invention transitions from traditional series transmission (which reduces speed) to parallel transmission architecture. By arranging multiple lever boosters in parallel and using circumferential lever arms distributed around the eccentric wheel, the system adds torque in a different dimensional approach - through spatial distribution of lever arms rather than sequential gear reduction.
2Force
If multiple reducers are connected in series to increase torque, then torque multiplication is enhanced, but rotation speed becomes extremely low or zero
Solution Approach 1:
Instead of connecting reducers in series, the invention segments the torque multiplication function into multiple parallel lever boosters. Each booster operates independently at its own speed, and their torques are combined through the parallel architecture, eliminating the speed degradation that occurs with series connections.
Solution Approach 2:
Multiple circumferential lever boosters are merged in parallel configuration, combining their torque outputs while maintaining a common speed profile. The parallel merging of multiple units achieves cumulative torque multiplication without the compounding speed reduction inherent in series connections.
3Force
If traditional mechanical transmission is used to multiply torque, then torque force is increased, but the structure becomes complex and requires series connections
Solution Approach 1:
The circumferential lever booster is designed as a universal module that simultaneously achieves torque multiplication, speed maintenance, and self-locking functionality. The same basic structure can be deployed in parallel multiple times, reducing overall system complexity through standardization and modularity rather than requiring complex series-connected mechanisms.
Solution Approach 2:
The invention uses circumferential distribution of lever arms around the eccentric wheel, utilizing the circular dimension to multiply torque. This spatial arrangement allows multiple lever arms to act simultaneously in parallel, achieving torque multiplication through geometric distribution rather than through complex sequential mechanical stages.

AI summary
A circumferential lever booster includes a transmission part that is fixedly connected to an input eccentric wheel; the input eccentric wheel is movably connected to a circumferential surface of an acting force end on a lever arm group by means of a bearing; the other end of the lever arm group is movably supported with a circumferential support seat; and the circumferential surface of the lever arm group at said end is movably connected to a bearing fixed on the eccentric axis of an output eccentric wheel; a lever prying force is applied while a circumferential swinging force is transmitted, so as to act on the output eccentric wheel; and the eccentric wheel is fixedly connected to a transmission part to output a boost. The circumferential lever booster can achieve boosting when the eccentricity of the input eccentric wheel and output eccentric wheel is equal.
