Description
Technical field
This utility model relates to the double helical spurgear drive mechanism of a kind of change speed gear box.
Background technology
Spur gear change speed gear box is due to the design of its relative moderate and cost of manufacture, at present in China still
There is bigger market；But produce when its delivering power is little, relative volume weight is relatively big and runs
Huge noise still bring certain puzzlement to user.
Utility model content
This utility model aims to overcome that above-mentioned the deficiencies in the prior art, it is provided that a kind of holding is relatively
Design and cost of manufacture lowly, and change speed gear box delivering power can be improved, reduce its volume and reduction
The double helical spurgear drive mechanism of noise when it runs.
The technical solution of the utility model is: the double helical spurgear drive mechanism of a kind of change speed gear box,
Including the driving gear being arranged in gear box and driven gear, gone back driving gear connects
On output shaft in described casing, described driving gear and driven gear are all herringbone tooth
Wheel, is provided with spacing gathering sill, described spacing gathering sill slidably connects slide block in described casing
Connecting to have on bearings plate, described slide block or described bearings plate to connect on described slide block has
Piston rod, described bearings plate is additionally provided with a bearing, and described driven gear passes through gear shaft
It is connected with described bearing.
Further, described spacing gathering sill is arranged on slider support plate, described slider support
Plate is fixed in described casing.
Preferably, described spacing gathering sill has two, and described slide block has two pieces.
Further, described spacing gathering sill is up-narrow and down-wide trapezoidal cell body, described spacing leads
It is all arc-shaped transition chamfering to the two of groove drift angles and two interior angles.
Further, described slide block includes connecting portion and the shape phase with described spacing gathering sill
Corresponding sliding part, described connecting portion is inverted trapezoidal and top is connected with described bearings plate
Connecing, described connecting portion and described sliding part are formed in one structure.
Further, described slide block and described bearings plate are welded as a whole.
Further, described bearings plate is flat square or disc.
Further, described bearings plate is provided with a through hole, and described bearing is inlayed or interference
It is matched with in described through hole.
Further, described bearing is needle-type bearing.
The beneficial effects of the utility model are: bearings plate of the present utility model is existed by slide block
Move in the stroke of chute, realize driving tooth turbine driven gear by the drive of piston rod
Engagement and separation, compact conformation is simple, it is the cheapest to be designed and manufactured as this；Driving tooth
Wheel and driven gear are double helical spurgear, can effectively offset stress suffered by gear, can bear relatively
Big power, and noise when running is low；Spacing gathering sill and the slide block of design also prop up to bearing
Fagging provides the support force of abundance.
Accompanying drawing explanation
Fig. 1 is axonometric chart of the present utility model.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is made into
Step specific description.
As it is shown in figure 1, the double helical spurgear drive mechanism of a kind of change speed gear box, including being arranged at change
Driving gear (not shown) in speed box body 1 and driven gear 3, driving gear is connected to
On output shaft (not shown) in casing 1, driving gear and driven gear 3 are all herringbone
Gear, is fixed with slider support plate 5, slider support plate 5 is arranged with two in parallel in casing 1
The spacing gathering sill of bar 6, spacing gathering sill 6 is up-narrow and down-wide trapezoidal cell body, spacing gathering sill
Two drift angles and two interior angles of 6 are all arc-shaped transition chamfering, on two spacing gathering sills 6 all
Slidably connect slide block 7, slide block 7 include integrated formed structure connecting portion 71 and with limit
The corresponding sliding part 72 of shape of position gathering sill 6, connecting portion 71 be inverted trapezoidal and top and
Bearings plate 8 phase is welded, and bearings plate 8 is flat square, bearings plate 8
It is connected with the piston rod (not shown) of gearshift, bearings plate 8 is additionally provided with one and leads to
Hole (not shown), in through hole, interference fit has needle-type bearing 9, driven gear 3 to pass through tooth
Wheel shaft 10 is connected with bearing 9.
Bearings plate of the present utility model is moved in the stroke of chute by slide block, logical
The drive crossing piston rod realizes driving gear and the engagement of driven gear and separation, compact conformation letter
Singly, this it is designed and manufactured as the cheapest；Driving gear and driven gear are herringbone tooth
Wheel, can effectively offset stress suffered by gear, can bear bigger power, and noise when running
Low；The spacing gathering sill of design and slide block provide the support force of abundance also to bearings plate.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this reality
With novel, all within spirit of the present utility model and principle, any amendment of being made, equivalent
Replacement, improvement etc., within should be included in protection domain of the present utility model.
