The herringbone gear pump (Figure 3-3) is a modification of the spur gear design. The liquid is pumped in the same manner as in the spur gear pump. However, in the herringbone pump, each set of teeth begins its fluid discharge phase before the preceding set of teeth has completed its discharge phase. This overlapping and the relatively larger ...

2023年10月1日 · The following subsections describe gear rolling, which represents a material-saving and productive bulk metal forming process, and power skiving, which features flexibility for both soft- and hard-machining of outer herringbone gear wheels and inner herringbone ring gears [2]. Furthermore, both processes may be combined in one process chain.

The herringbone gear is the most important elastic element in the HSGT, and the excitation on both sides of it is combined by the undercut groove. It is necessary to consider the meshing stiffness of the helical gears on both sides separately [23] , especially when the positions of the left and right teeth are staggered [24] .

The change process of the motion characteristics of the herringbone gear transmission system is as follows: when the dimensionless meshing frequency ωe gradually increases from 0.1, the motion state of the herringbone gear transmission system is in multiple periodic motion; when ω e reaches 0.76, the herringbone gear transmission system ...

2024年3月15日 · Herringbone gear pairs are widely used in high-power transmission devices. For instance, large marine herringbone gear transmissions can achieve single shaft transmission power of up to 50 MW and pitch circle linear speeds of up to 120 m/s [1].

2024年3月15日 · The herringbone gear consists of two helical gears at the left and right ends, which need to be machined separately [14]. Fig. 3 illustrates a schematic diagram of the herringbone gear machining process. Due to the machining process, the helical gears machined at both ends may have different machining errors.

Herringbone gear pair, also known as double helical gear pair, consists of left and right two helical gear pairs and the middle relief groove, theoretically can automatically balance the axial force generated by the left and right helical gear pair, and has the advantages of high contact ratio, strong load-bearing capacity, smooth transmission, compact structure, etc., so it is widely used …

2022年1月1日 · Herringbone gear sets Herringbone or double helical gears offer many advantages over the predominantly used helical or spur geared variants, such as high power density due to compact design. The neutralization of axial forces due to the symmetrical arrangement of left- and right-hand helical gearing enables the use of smaller bearings and …

2023年2月1日 · The 3-D model of herringbone gear and its meshing process is shown in Fig. 1. Due to the existence of a helical angle, the meshing of herringbone gear is first entered by a point A of the gear tooth. With the continuous rotation of the gear, the contact line gradually extends to the whole tooth width, such as the DM state.

2020年2月1日 · The HPGT is mainly composed of an input shaft connected to the motor, a herringbone sun gear, N herringbone planet gears, a carrier, a herringbone ring gear and an output shaft connected to the load. The herringbone sun gear can float radially and the herringbone planet gears are supported by a plain bearing mounted on the carrier.
