Compare and explain the disadvantages of ZLY reducer with other types of reducers

ZLY reducer is a two-stage transmission hard tooth surface cylindrical gear reducer. The following is a comparison of its disadvantages with other common types of reducers:

Comparison with planetary gearbox

ZLY reducer:

Disadvantages: Compared to planetary gearboxes, its structure is not compact enough, and its volume and weight are relatively large; At the same reduction ratio, the precision of planetary reducers is higher, and the rotational clearance of ZLY reducers is relatively larger.

Planetary reducer:

Disadvantages: High price and relatively high manufacturing cost; The overload capacity is relatively weak, and faults are prone to occur when encountering large impact loads.

Comparison with worm gear reducer

ZLY reducer:

Disadvantages: The reduction ratio is relatively small. Worm gear reducers can achieve a larger reduction ratio in a single stage, while ZLY reducers usually require multi-stage transmission to achieve similar reduction effects; The structure of the worm gear reducer is more compact, while the ZLY reducer is slightly inferior in this regard.

Worm gear reducer:

Disadvantages: Insufficient transmission efficiency, easy wear and tear, and high long-term operating costs; Only orthogonal and vertical output forms are available, with certain limitations in application scenarios; The process of casting copper material for worm gears is complex, and the cost of small-scale production is high.

Comparison with cycloidal pinwheel reducer

ZLY reducer:

Disadvantages: The structure of the cycloidal pinwheel reducer is simpler and more compact, while the ZLY reducer is not as complex and compact in structure as the cycloidal pinwheel reducer; In some low-power and high speed ratio application scenarios, the cost-effectiveness of cycloidal pinwheel reducer is higher.

Cycloidal pin wheel reducer:

Disadvantages: The manufacturing process is relatively complex and the cost is high; In high-speed and high-power application scenarios, its performance is not as good as hard tooth surface gear reducers such as ZLY reducers; The transmission efficiency is generally between 80% and 90%, which is lower than that of ZLY reducers.
