Problems solved by technology

If the center of gravity of the weight of the propeller is unevenly distributed, it will cause a dynamic imbalance during the rotation of the propeller, causing the hull to vibrate violently
The existing propeller manufacturing process is difficult to control the mass distribution of the blade, and the precision is low, which affects its distribution balance and structural strength, and it is complicated and inconvenient to operate

Abstract

A propeller manufacturing process, the blades of the propeller are completed in a multi-layer manner, which can better control its mass distribution, improve its product precision, and effectively reduce the unbalanced movement of the propeller due to the uneven distribution of the center of gravity of the weight; the propeller After the leaves are completed, they are bonded by pouring foam. The process is simple and effective, and can meet the requirements of propeller strength and mass distribution, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a manufacturing process of a propeller, in particular to a manufacturing process of an air propeller. Background technique [0002] The air propeller is a device that converts the rotational power of the engine into propulsion or lift by the rotation of the blades in the air. It consists of multiple blades and a central hub. The production of the air propeller not only needs to ensure the high strength requirements of the propeller, but also needs to strictly control the distribution of its weight center of gravity while ensuring the high strength of the air propeller. If the center of gravity of the weight of the propeller is not evenly distributed, it will cause a dynamic imbalance during the rotation of the propeller, which will cause the hull to vibrate violently. The existing propeller manufacturing process is difficult to control the mass distribution of the blades, and the precision is low, which affects its distributi...
