Description
Technical field
The present invention relates to a kind of double helical spurgear transmission mechanism of gearbox.
Background technology
Straight-tooth wheel-speed regulating change box still has larger market in China at present due to the design and cost of manufacture of its relative moderate；
But the huge noise produced when its delivering power is small, relative volume weight is larger and runs still brings certain to user
Puzzlement.
The content of the invention
Present invention aims to overcome that above-mentioned the deficiencies in the prior art keep lower designing and being fabricated to there is provided one kind
This, and the double helical spurgear transmission mechanism that gearbox delivering power can be improved, its volume is reduced and reduce noise when it runs.
The technical scheme is that：A kind of double helical spurgear transmission mechanism of gearbox, including it is arranged at gearbox case
Internal driving gear and driven gear, the driving gear is connected on the output shaft in the casing, the driving gear
All it is to be provided with spacing guide groove, the spacing guide groove to slidably connect in double helical spurgear, the casing with driven gear
It is connected with sliding block, the sliding block on bearings plate, the sliding block or the bearings plate and is connected with piston rod, the axle
Hold and a bearing is additionally provided with supporting plate, the driven gear is connected by gear shaft with the bearing.
Further, the spacing guide groove is arranged on slider support plate, and the slider support plate is fixed on the case
In vivo.
Preferably, the spacing guide groove has two, and the sliding block has two pieces.
Further, the spacing guide groove is up-narrow and down-wide trapezoidal cell body, two drift angles of the spacing guide groove
All it is arc-shaped transition chamfering with two interior angles.
Further, the sliding block includes connecting portion and the sliding part corresponding with the shape of the spacing guide groove,
The connecting portion is inverted trapezoidal and top is connected with the bearings plate, and the connecting portion and the sliding part are integrated into
Type structure.
Further, the sliding block and the bearings plate are welded as a whole.
Further, the bearings plate is flat square or disc.
Further, the bearings plate is provided with a through hole, and the bearing is inlayed or in interference fit with the through hole
It is interior.
Further, the bearing is needle-type bearing.
The beneficial effects of the invention are as follows：The bearings plate of the present invention is moved by sliding block in the stroke of chute,
The engagement and separation of driving gear and driven gear are realized by the drive of piston rod, compact conformation is simple, be designed and manufactured as
This is more cheap；Driving gear and driven gear are double helical spurgear, can effectively offset stress suffered by gear, can bear compared with
Big power, and noise during operation is low；The spacing guide groove and sliding block of design also provide sufficient branch to bearings plate
Support force.
