Abstract

The utility model discloses a split-type herringbone gear which is characterized by comprising a crankshaft, a small gear shaft and a herringbone gear body. The herringbone gear body is split into a left-handed gear and a right-handed gear by a large gear ring. The two ends of the crankshaft are provided with the left-handed gear and the right-handed gear respectively. The small gear shaft is in linkage through the left-handed gear and the right-handed gear at the two ends of the crankshaft. The split-type herringbone gear has the advantages that the machining difficulty of the left-handed gear and the machining difficulty of the right-handed gear are small, the machining cost is greatly reduced, special requirements of equipment do not exist, and the application range is wide.

Description

Split type herringbone gear
Technical field
The utility model relates to a kind of herringbone gear, relates in particular to a kind of split type herringbone gear.
Background technique
domestic drilling pump driving gear pair generally all adopts herringbone gear, the left-handed gear of little tooth axle becomes herringbone tooth with the right-hand teeth wheel shape and is positioned at the neutral position of axle, two teeth are at most only apart tool withdrawal groove, the left-handed gear of bull gear and dextrorotation gear are connected to an integral body and form double helical spurgear, be assemblied in the neutral position of bent axle, two teeth are at most only apart tool withdrawal groove, the assembling mode of this structure difficulty in assembly process strengthens, the herringbone gear processing difficulties, greatly increased cost, also very high to the requirement of equipment simultaneously, therefore, for addressing the above problem, the spy provides a kind of new technological scheme to satisfy the demands.
The model utility content
The purpose of this utility model is to provide a kind of split type herringbone gear.
The technical solution adopted in the utility model is:
Split type herringbone gear, comprise bent axle, little tooth axle and herringbone gear, described herringbone gear is split as left-handed gear and dextrorotation gear by bull gear, and described crankshaft two end is respectively fitted with left-handed gear and dextrorotation gear, and described little tooth axle is by left-handed gear and the dextrorotation gear-linked of crankshaft two end.
The utility model has the advantages that: the difficulty of processing of left-handed gear and dextrorotation gear is little, and processing cost reduces greatly, and is also without specific (special) requirements, applied widely to equipment.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, left-handed gear, 2, bent axle, 3, little tooth axle, 4, the dextrorotation gear.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not form the restriction to the utility model protection domain.
As shown in Figure 1, split type herringbone gear of the present utility model, comprise bent axle 1, little tooth axle 2 and herringbone gear, herringbone gear is split as left-handed gear 1 and dextrorotation gear 4 by bull gear, bent axle 2 two ends are respectively fitted with left-handed gear 1 and dextrorotation gear 4, and little tooth axle 3 is by left-handed gear 1 and 4 interlocks of dextrorotation gear at bent axle 2 two ends.
The utility model has the advantages that: the difficulty of processing of left-handed gear and dextrorotation gear is little, and processing cost reduces greatly, and is also without specific (special) requirements, applied widely to equipment.
