Abstract
The utility model provides a drive unit is applied to moving platform, including the planet wheelset, every planet wheelset includes wheel and wheel branch. Wherein, be expert at and still installed a free scrolling's wheel in the middle of the star gear group. According to drive unit, have better drive characteristic, transmission needs in the time of can satisfying moving platform more the building is climbed to the barrier.
Description
Technical field
This utility model relates to a kind of gear unit, belongs to movement mechanisms field.
Background technology
Planet gear type structure is realized around central shaft upset by each planetary gear set (generally 3 or 4)
Obstacle detouring, stair activity.Structure can be divided into single planetary bevel gear and dual planetary gear two kinds.So-called single planetary bevel gear, refers to
Be on horizontal plane, to be configured with a pair identical planetary gear set, dual planetary gear then refers to front and back have two
To identical planetary gear set.
But, it is no matter single planetary bevel gear or dual planetary gear when some special barriers, often
Make one group or many group wheels unsettled or touch planet carrier, damage equipment, have impact on the normal of machine
Serviceability.
Utility model content
The purpose of this utility model is the drawbacks described above for prior art, proposes a kind of gear unit,
It is applied to the mobile platforms such as mobile dolly, there is preferable drive characteristic, mobile platform obstacle detouring can be met
Climb transmission needs during building.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of gear unit, is applied to mobile platform, it is characterised in that:
Including planetary gear set, each planetary gear set includes wheel and wheel pole.
Wherein, there is also mounted one in the middle of each planetary gear set can free rolling wheel.
Described can be placed with two bearings inside free rolling wheel, one end back-up ring positions, other end
Add pad screw-driving.
Meanwhile, this utility model also provides for a kind of mobile platform, including described gear unit.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that this utility model moves dolly.
Fig. 2 is the front view of this utility model gear unit.
Fig. 3 is this utility model gear unit part sectioned view.
(note: shown structure in accompanying drawing is simply to illustrate that the signal of this utility model feature, not
It is intended to according to structure shown in accompanying drawing.)
Detailed description of the invention
As it is shown in figure 1, according to gear unit described in the utility model, be applied to the occasions such as mobile dolly,
Wherein move dolly to include: gear unit, connecting plate 1, adjustable plate 3, connecting plate 24, pad,
Screw, nut, bearing block, motor cabinet one, motor cabinet two.
Wherein, mobile dolly can realize the distance regulation of before and after's gear unit, and connecting plate 1 both sides have two
The gear unit that group seals, connecting plate 24 both sides have two groups of gear units sealed, two pieces of connections equally
Plate is connected by middle adjustable plate 3.
Adjustable plate 3 one end is fixed, and other end has notch, is connected by pad, screw and nut,
Distance regulation can be realized within the specific limits.Concrete, see Fig. 1, connecting plate 1 and connecting plate 24
Being connected by adjustable plate 3, adjustable plate 3 is provided with multiple fixing screw, a portion screw is fixed
Connecting plate 1 and adjustable plate 3, another part screw fixed connecting plate 24 and adjustable plate 3.In regulation
It is additionally provided with chute one on plate 3, connecting plate 1 is provided with chute two, described chute one and chute two
Being connected by above-mentioned screw, described screw can move in two chutes, when stress, between two screws between
Away from changing, and then change the spacing between two connecting plates.
Owing to the mobile dolly of said structure is divided into two-part, front and back two parts are by middle adjustable plate even
Connect, run into step not of uniform size, by this function just can solution must not the problem of climb steps smoothly.
As in figure 2 it is shown, according to gear unit described in the utility model, including planetary gear set 1, each
Planetary gear set includes wheel and wheel pole, by bearing block, motor cabinet one, motor cabinet two and motor phase
Even, power is provided for planetary gear set 1, it is achieved control.
Preferably, each planetary gear set 1 includes three wheel poles and three wheels.
As it is shown on figure 3, according to gear unit described in the utility model, pacify again in the middle of planetary gear set 1
Filled one can free rolling wheel 12, be placed with two bearings 13 inside rotatable wheel 12, one
End back-up ring 16 positions, and other end is added pad 15 screw 14 and tightened.
In prior art, other similar obstacle detourings climb building equipment when run into special obstacle thing, barrier point
Portion can withstand on planet carrier, and long-time occur that this situation can be damaged planetary wheel carrier or make wheels unsettled,
And according to gear unit described in the utility model, its planetary gear set more than 1 wheel 12 free to rotate,
The when of running into the barrier of distinctive appearance, planet carrier will not be encountered, encounter freely rotatable wheel 12,
Barrier can be passed through, planetary gear set will not be made to soar, relatively general obstacle detouring climbing machine device, improve
Its work efficiency, solves the problem that wheels soar, barrier encounters planetary wheel carrier damage equipment.
Due to planetary gear set 1 substantially closing, foreign material cannot be wound into inside gear, it is ensured that sets
Standby stability and cleannes.
In sum, according to gear unit described in the utility model, have the advantage that
Planetary gear set is optimized, general planetary gear set, no matter is triangle, quadrangle or more
Polygon number, centre does not the most rotate wheel, has the benefit rotating wheel is only to run into what special shape
Barrier, can cross over smoothly, without impinging on bracing frame, protects machinery equipment.Planetary gear set institute
Gear be all in the gear-box sealed, will not be wound around dirty, it is ensured that service behaviour stable and setting
Standby health.
The above, preferred embodiment the most of the present utility model, it is not intended to limit this practicality new
The protection domain of type, all made within spirit of the present utility model and principle any amendment, equivalent replace
Change and improvement etc., within should be included in protection domain of the present utility model.
