Axial flow impeller

Abstract

The invention discloses an axial flow impeller. The axial flow impeller comprises a gear shaft which is arranged in a front-back mode, and further comprises a front release structure arranged on the front side of the gear shaft and a back release structure arranged on the back side of the gear shaft, wherein the front release structure and the rear release structure are in central symmetry; and the front release structure comprises a gear shaft sleeve sleeving on the gear shaft, a one-way bearing sleeves the gear shaft sleeve, an outer ring of the one-way bearing is connected with a swing rod,the swing rod can drive the outer ring to rotate, and a lower ejection rod capable of moving up and down abuts against the lower portion of the swing rod. According to the axial flow impeller, the swing rod is pushed by the lower ejection rod so as to allow the outer ring of the one-way bearing to rotate in the opposite direction, the outer ring and an inner ring of the one-way bearing can be clamped instantly so that the gear shaft sleeve can stop moving for a moment or the speed of the gear shaft sleeve can be reduced for a moment, and therefore a speed difference can be generated between the gear shaft sleeve and the gear shaft for a moment, the clamping force between the gear shaft and the gear shaft sleeve is lost, the gear shaft is easy to move forwards and backwards, and gear shifting is achieved. The axial flow impeller is used for gear shifting of a machine tool.

Description

technical field [0001] The invention relates to an axial flow impeller which can improve the total pressure and efficiency of aerodynamic hydrodynamic equipment components at low rotational speed. Background technique [0002] Axial flow fans have a wide range of uses, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans and air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high. The existing axial flow impeller has not undergone scientific hydrodynamic calculation, and its total pressure is low and its efficiency is low under low rotation speed. Contents of the inve...
