Abstract

The invention discloses a calculating method of a thermal deformation of a tooth surface of a herringbone gear. The calculating method comprises the following steps: S1, acquiring relevant data of theherringbone gear; S2, determining temperature values of left and right tooth surface points of the herringbone gear along a tooth meshing line direction; S3, determining temperature values of the left and right tooth surface points of the herringbone gear; S4, calculating coordinate values of the left and right tooth surface points of the herringbone gear before and after the thermal deformation;and S5, calculating the thermal deformation of the tooth surface of the herringbone gear. The calculating method disclosed by the invention can quickly and easily calculate the thermal deformation ofthe tooth surface of the herringbone gear; and as the calculating method is simple, an engineering technician can master the method easily.

Description

technical field [0001] The invention relates to the technical field of gear transmission systems, in particular to a method for calculating the thermal deformation of a herringbone gear tooth surface. Background technique [0002] Gear thermal deformation is an important factor causing gear shock, vibration and unbalanced load. The calculation of the thermal deformation of the gear tooth surface is the key to the thermal deformation modification of the gear. Herringbone gears are widely used in high-speed and heavy-duty transmissions because of their high load-carrying capacity and good working stability. Under high-speed and heavy-load conditions, the thermal deformation of gears is obvious. Therefore, it is of great engineering significance to carry out the calculation and research of the thermal deformation of the tooth surface of herringbone gears. [0003] At present, the calculation of the thermal deformation of the gear tooth surface mostly adopts the finite element...
