Description
Technical field
The invention belongs to slew gear technical field, more particularly to the flexibility such as a kind of electric wire, cable, oil pipe, tracheae, water pipe
Circuit or pipeline slew gear.
Background technology
What the motion of joint of robot was typically all completed jointly by equipment such as motor, driver, encoders, these equipment
If being required for the main lines such as power line, signal wire or pipeline, a kind of common motion mode of joint of robot is rotary motion, when
When movable joint rotates, related circuit or pipeline also can and then rotate, and the anglec of rotation if desired is larger, for example, it is desired to
± 360 ° of revolutions, and circuit or pipeline are guided or limited without suitable method, may result in circuit or pipeline occurs
Winding, influences the normal rotation in joint and the service life of circuit or pipeline.Meanwhile, in order that clean and tidy outside joint of robot
It is attractive in appearance, it usually needs circuit or pipeline are arranged on to the inside of joint of robot.
One of scheme of slew gear is the structure using slip-ring brush in the prior art, and it includes slip ring and brush, rotation
When turning, brush is slided on slip ring, it is possible to achieve the transmission of signal and power supply, still, slip-ring brush structure space-consuming
Larger, in installing space by limited time, this structure can not be used；Simultaneously as the effect of centrifugal force and unbalanced moments, slip ring
Shake is inevitably generated, therefore the anti-tampering ability of this structure is poor, causes jitter.
Another scheme of slew gear is to use drag chain system in the prior art, and electricity can be improved by drag chain system
The flexible circuitries such as line, cable, oil pipe, tracheae, water pipe or pipeline are distributed messy situation, are allowed to neat, regular and are arranged in one
Rise, it is not only attractive in appearance, and traction can be played to the flexible circuitries such as built-in electric wire, cable, oil pipe, tracheae, water pipe or pipeline
And protective effect.But, the main component chain flexes radius of existing drag chain system can not be too small, therefore in narrow space
Interior, existing drag chain system can not be used.
Therefore, how in the limited occasion of installing space, it is ensured that internal wiring or pipeline are not twined in rotary motion
Around the service life of raising circuit or pipeline, as those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
The technical problems to be solved by the invention are：A kind of circuit or pipeline slew gear are provided, it is simple in construction, installing
The occasion of limited space, it is ensured that internal wiring or pipeline are not wound in rotary motion, improves the use of circuit or pipeline
Life-span.
In order to solve the above technical problems, the technical scheme is that：Circuit or pipeline slew gear, including：
The external gear and ring gear being coaxially disposed, one end of the circuit or pipeline are fixedly connected with the external gear, another
End is fixedly connected with the ring gear；

As a further improvement, the planet carrier includes the first planet carrier body being fixedly installed togather by fastener
With the second planet support body, the inner side of the first planet carrier body and the second planet support body is located at raised two of the outer radial respectively
End face；The outside of the first planet carrier body and the second planet support body is located at the both ends of the surface of the interior radial protrusion respectively.
As a further improvement, the inner pallet is fixed in first module, and the outer tray is fixed on second unit
On, the first module and the second unit can be relatively rotated.
As an improvement, the planetary gear has multiple, the revolution of multiple relatively described external gears of the planetary gear
Axis annular array is distributed.
As an improvement, the circuit or pipeline have multiple, and the multiple circuits or pipeline are returned along the external gear
Shaft axis are arranged in juxtaposition in a row.
As an improvement, directive wheel is installed with the planetary gear, the circuit or pipeline bypass described lead
To wheel.
As a further improvement, the external diameter of the directive wheel is identical with the planetary external diameter.
Employ after above-mentioned technical proposal, the beneficial effects of the invention are as follows：
Because circuit or pipeline slew gear devise external gear, ring gear, planet carrier and planetary gear, if thus external tooth
Take turns as driving gear, power passes to ring gear through external gear and planetary gear, so that external gear and ring gear being capable of phases
To revolution, now circuit or pipeline synchronously carry out take-up and unwrapping wire process on external gear and ring gear respectively, it is ensured that inner wire
Road or pipeline are not wound in rotary motion；Conversely, if ring gear is active gear ring, power is through ring gear and planetary gear
Pass to external gear so that external gear and ring gear can relative revolution, now circuit or pipeline respectively in external gear and
Take-up and unwrapping wire process are synchronously carried out on ring gear, it is ensured that internal wiring or pipeline are not wound in rotary motion, improved
The service life of circuit or pipeline.
Circuit or pipeline slew gear that the present invention is provided, simple in construction, the occasion being limited in installing space, it is ensured that internal
Circuit or pipeline are not wound in rotary motion, and the drawing force of folding and unfolding circuit or pipeline will not be applied to circuit or pipeline
On, it can extend using by the life-span.
Because the inner pallet is fixed in first module, the outer tray is fixed on second unit, and described first is single
First and described second unit can be relatively rotated, thus can impart power to external gear by first module, or pass through second
Unit imparts power to ring gear.
Because the planetary gear has multiple, the axis of rotation circular array of multiple relatively described external gears of the planetary gear
Column distribution so that power transmission is more steady.
Because the circuit or pipeline have multiple, the axis of rotation of the multiple circuits or pipeline along the external gear is arranged side by side
Arrangement is in a row, when circuit or more pipeline quantity, is designed into one overall, facilitates it with external gear and ring gear
Connection.
Due to being installed with directive wheel on the planetary gear, when in use, directive wheel is positive and negative with planet gear synchronous
Rotate, circuit or pipeline can be play the guiding role.
Because the external diameter of the directive wheel is identical with the planetary external diameter, it so can preferably ensure circuit
It elasticity and will not wind, realize the synchronous progress of ring gear and external gear unwrapping wire and take-up.
