Novel balancing weight
By designing a new type of counterweight, the position of the fixed block is adjusted by using a handle to drive the worm gear and worm wheel, which solves the problem that traditional counterweights cannot dynamically adapt, thus achieving inertial balance of the gearbox and extending its service life.

AI Technical Summary
Technical Problem
Traditional counterweights cannot dynamically adapt, causing the gearbox to shift due to inertial force when gears wear, load changes, or parts are replaced. This results in ineffective adjustment, shortened equipment lifespan, and high maintenance costs.
Method used
A novel counterweight is designed that, by holding the handle, drives the worm gear, worm wheel, and threaded rod to adjust the positions of the first and second fixed blocks, achieving precise balance of inertial forces. The self-locking property of the worm gear ensures stable positioning.
Benefits of technology
The system enables dynamic adjustment of the counterweight system, extends the service life of the gearbox, and improves the operational stability and maintenance efficiency of the equipment.

Abstract
The utility model discloses a novel balancing weight which comprises a circular ring, the bottom of the circular ring is coaxially and fixedly connected with a connecting shaft, one side of the circular ring is provided with a first fixing block and a second fixing block, the top of the second fixing block is provided with a first groove, the bottom of the second fixing block is provided with a second groove, and the connecting shaft is coaxially and fixedly connected with the connecting shaft. A third groove is formed in the bottom of the first fixing block, and connecting assemblies are arranged between the outer wall of the circular ring and the first fixing block and between the outer wall of the circular ring and the second fixing block. The positions of the first fixing block and the second fixing block can be driven to be adjusted by holding the handle, a counterweight system can be adjusted, inertia can be balanced, the service life of a gearbox is prolonged, and the stability of the two fixing blocks after the positions are adjusted is guaranteed through the self-locking performance of the worm gear and the worm.
