Abstract
The utility model discloses a combined dislocation herringbone gear, this herringbone gear include left ring gear (1), right ring gear (2), hank system hole bolt (3), nut (4), packing ring (5) and hub (6), and left ring gear (1) and right ring gear (2) is assembled respectively and is used simultaneously hank system hole bolt (3), nut (4) and packing ring (5) in hub (6) both sides and fix and lock, characterized by: a left side ring gear (1) is left -hand teeth or right -hand teeth, and the helical angle of right ring gear (2) is revolved to opposite with left ring gear (1). The utility model discloses a contact ratio and overlap ratio is high, smooth operation, and the noise is little, requires lowly to the processing equipment.
Description
Technical field
The utility model relates to herringbone gear, is specifically related to a kind of combined dislocation herringbone gear.
Background technique
Split at shale oil air pressure in the high rotation speed gear boxes such as pump power case, fast chamber and mostly adopt herringbone gear drive mechanism.Existing herringbone gear is all the monolithic construction along gear split symmetry, and this integral herringbone gear is generally divided into band withdrawing grooved and without withdrawing grooved two type.Wherein, the axial dimension of band withdrawing grooved herringbone gear is excessive, easily causes the volume and weight of complete machine excessive; Although little without withdrawing grooved herringbone gear axial dimension, higher to the required precision of process equipment, and when running up, flank engagement extruding lubricant oil is shunted to both sides, two strands of lubricant oil wherein to intermediate distributary cannot draining, impacts, thus produces vibration and noise.
Summary of the invention
The purpose of this utility model is: provide a kind of combined dislocation herringbone gear, this herringbone gear contact ratio is high, and axial dimension is little, smooth running during high speed operation, and noise is little, less demanding to process equipment.
The purpose of this utility model is achieved in that this herringbone gear comprises left gear ring, right gear ring, strand drilling bolt, nut, packing ring and wheel hub, and left gear ring and right gear ring are assemblied in wheel hub both sides respectively and use strand drilling bolt, nuts and washers fixing and locking; It is characterized in that: left gear ring is left-hand teeth or right-hand teeth, the helix angle rotation direction of right gear ring is contrary with left gear ring.
Wherein, the teeth portion of described left gear ring and the teeth portion of right gear ring stagger half tooth distance, namely the teeth groove of left gear ring and the teeth portion of right gear ring symmetrical, left gear ring and right gear ring is engaging-in and to nibble out be continuous print gradually.
Wherein, the gap between described left gear ring and right gear ring is very little.
Wherein, described combined dislocation herringbone gear operationally, shunt to both sides, and the lubricant oil wherein to intermediate distributary carries out draining by the teeth groove of opposite side by flank engagement extruding lubricant oil.
The beneficial effects of the utility model are: 1, in this combined dislocation herringbone gear, each part is independently processed laggard luggage and joined, and greatly reduces the requirement to process equipment; 2, the teeth portion of left gear ring and the teeth portion of right gear ring stagger half tooth distance, the i.e. teeth groove of left gear ring and the teeth portion symmetry of right gear ring, left gear ring and right gear ring is engaging-in and to nibble out be continuous print gradually, engaging-in and nibble out frequency comparatively non-dislocated herringbone gear double, substantially increase the contact ratio of gears meshing, improve the stationarity of gears meshing, reduce noise simultaneously; 3, the gap between left gear ring and right gear ring is very little, thus can make the smaller herringbone gear of axial dimension, reduce the volume of complete machine, weight and cost; 4, combined dislocation herringbone gear operationally, and flank engagement extruding lubricant oil is shunted to both sides, and the lubricant oil wherein to intermediate distributary carries out draining by the teeth groove of opposite side, reduces impact and noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is perspective view of the present utility model.
In figure: 1 left gear ring; 2 right gear rings; 3 strand drilling bolts; 4 nuts; 5 packing rings; 6 wheel hubs.
Embodiment
As shown in Figure 1 and Figure 2, this herringbone gear comprises left gear ring 1, right gear ring 2, strand drilling bolt 3, nut 4, packing ring 5 and wheel hub 6, and left gear ring 1 and right gear ring 2 are assemblied in wheel hub 6 both sides respectively and use strand drilling bolt 3, nut 4 and packing ring 5 fixing and locking; It is characterized in that: left gear ring 1 is left-hand teeth or right-hand teeth, and the helix angle rotation direction of right gear ring 2 is contrary with left gear ring 1.
Wherein, the described teeth portion of left gear ring 1 and the teeth portion of right gear ring 2 stagger half tooth distance, namely the teeth groove of left gear ring 1 and the teeth portion of right gear ring 2 symmetrical, left gear ring 1 and right gear ring 2 is engaging-in and to nibble out be continuous print gradually.
Wherein, the gap between described left gear ring 1 and right gear ring 2 is very little.
Wherein, described combined dislocation herringbone gear operationally, shunt to both sides, and the lubricant oil wherein to intermediate distributary carries out draining by the teeth groove of opposite side by flank engagement extruding lubricant oil.
