Description
Technical field
The present invention relates to mechanical Gear Planet Transmission fields, more particularly, to electric vehicle driving wheel and the driving of aircraft blade
Deng a kind of specific boss planetary gear driver.
Background technique
Currently, the driving method of electronic heavy duty AGV (Autoguided vehicle, automated guided vehicle) is big both at home and abroad
Part drives using central motor, and power is transmitted to steering and driving axle by universal joint.It can according to the quantity of carrying vehicle bridge
It is divided into doube bridge and more bridges.The advantages of structural shape is technology relative maturity, and risk is small.But also there is disadvantage: conventional heavy-duty load-carrying
Vehicle bridge that vehicle uses slow down it is relatively low, with the high-revolving motor of mainstream currently on the market is more difficult matches, motor can not be allowed in height
Section work is imitated, the steering angle of conventional steering drive axle is smaller, and heavy duty vehicle longer for vehicle body, turning radius is larger,
It is not flexible.
It is deposited in the hub with the integrated universal wheel that motor directly drives currently, conventional planetary gear is mounted directly
In disadvantage: wheel especially heavy load vehicle wheel radial forces are huge, and planetary gear mechanism is easily-deformable, and the gear teeth easily damage
Bad, axial displacement also easily occurs for each gear of planetary gear mechanism.
The present invention focuses on solving the easily-deformable and each Gear axial displacement problem of planetary gear mechanism, innovates a kind of specific boss
Planetary gear driver, driven for electric vehicle driving wheel and aircraft blade etc..
Summary of the invention
For the problems of the prior art, it is an object of the invention to solve the easily-deformable and each gear shaft of planetary gear mechanism
To displacement problem, a kind of specific boss planetary gear, i.e., grinding tooth within the useful screwed plug in both sides of interior grinding tooth wheel is fixed are innovated
Take turns the concentric ring-steps that reference circle is most inner circle, planetary gear, sun gear the useful screwed plug in both sides it is fixed with gear
Reference circle is the concentric circular boss of outermost circle, and each boss thickness is identical, and planetary gear carrier is fixed on center shaft, carrier
On center planetary gear axis and planetary gear between have bearing, have bearing between sun gear and center planetary gear axis.
According to the design feature of planetary gear mechanism, interior grinding tooth wheel reference circle and planetary gear reference circle and sun gear divide
Degree circle is tangent with planetary gear reference circle, and each gear boss mutually supports at point of contact, and roll displacement only occurs, and does not slide
Dynamic displacement, in addition gear compound graduation circle is between root circle and outside circle, and when gear engagement, each specific boss can be to gear side
To limit.
The invention has the following advantages that specific boss structure is simple, each gear boss mutually supports at point of contact, enhances row
The rigidity of star gear mechanism and each gear, solves that planetary gear mechanism is easily-deformable, the gear teeth easily damage, planetary gear mechanism
The problem of axial displacement, easily occurs for each gear, and each gear of planetary gear mechanism can use spur gear, not need complexity
Double helical tooth or helical gear etc., greatly simplify process for machining and manufacturing.
Detailed description of the invention
Grinding tooth wheel 2- screwed plug is fixed to the concentric ring that grinding tooth wheel reference circle within both sides is most inner circle in Fig. 1 1-
Shape boss.
Fig. 2 1- planetary gear 2- screwed plug is fixed to both sides using planetary gear reference circle as the concentric garden of outermost circle
Shape boss.
Fig. 3 1- sun gear 2- screwed plug is fixed to the convex as the concentric circular of outermost circle using sun gear reference circle of both sides
Platform.
Fig. 4 1- carrier 2- is fixed together with the interior grinding tooth wheel 3- that screwed plug fixes concentric ring-steps to both sides with screwed plug
Heart circular boss to both sides planetary gear 3- with screwed plug fix concentric circular boss to both sides sun gear.
The front view and side view 1- carrier 2- of a kind of specific boss planetary gear driver of Fig. 5 are fixed with screwed plug
Concentric ring-steps to both sides interior grinding tooth wheel 3- with screwed plug fix concentric circular boss to both sides planetary gear 3- spiral shell
Sun gear of the fixed concentric circular boss of line bolt to both sides.
Specific embodiment
1 electric vehicle driving wheel: the outer circle of interior grinding tooth wheel with wheel hub is concentric fixes, the useful screwed plug in both sides of interior grinding tooth wheel
Grinding tooth wheel reference circle is the concentric ring-steps of most inner circle, the useful screw thread in both sides of planetary gear, sun gear within fixed
What bolt was fixed take gear compound graduation circle as the concentric circular boss of outermost circle, and each boss thickness is identical, and planetary gear carrier is fixed
On center shaft, the center planetary gear axis in carrier and there is bearing between planetary gear, sun gear and center planetary gear axis
Between have bearing, wheel hub exterior tire, motor driven whole planetary gear may be constructed integrated universal driving wheel.
2 aircraft blade driving devices: the outside diameter both ends of interior grinding tooth wheel are fixed with blade, blade center and interior grinding tooth wheel
With one heart, blade center can also coaxially be fixed with sun gear, is nibbled within the useful screwed plug in the both sides of interior grinding tooth wheel is fixed
Gear compound graduation circle is the concentric ring-steps of most inner circle, planetary gear, sun gear the useful screwed plug in both sides it is fixed with tooth
The concentric circular boss that reference circle is outermost circle is taken turns, each boss thickness is identical, and planetary gear carrier is fixed on center shaft, star
Center planetary gear axis on frame and there is bearing between planetary gear, there is bearing between sun gear and center planetary gear axis, electricity
Machine drives whole planetary gears, may be constructed integrated blade driving wheel.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
