Turn driving, inherit the feature of gear drive and Worm Wheel System respectively, both device for revolving and driving are suitable for middle height respectively
The application of speed and low speed, in terms of bearing capacity, the performance of Worm-gear type is better than tooth-like, and when using enveloping worm
When transmission, bearing capacity, non-deformability and transmission rigidity have further raising, but Worm-gear type revolution driving
Then it is inferior to tooth-like revolution driving in terms of efficiency.
Worm Wheel System also has the characteristics that reverse self-locking, i.e., worm gear can only be driven by worm screw, and cannot be by worm gear band
Dynamic worm movement.This characteristic can be widely applied to revolution driving in the equipment such as lifting, high altitude operation, new energy,
Greatly improve the operation stability of host and the safety coefficient of operation.
Device for revolving and driving is compared with traditional deceleration device, with reduction ratio is big, bearing capacity is high, simple installation, is easy to
The features such as installation space, is saved in maintenance.
But the reduction ratio of device for revolving and driving nevertheless suffers from limitation, in order to realize the defeated of higher reduction ratio and more low speed
Out, other external deceleration devices again on the basis of device for revolving and driving are needed toward contact, caused not compact enough, integrated in structure
The disadvantages of spending low, higher cost, cannot fully meet the needs of different use occasions.
Utility model content
The utility model integrates device for revolving and driving and planetary reducer, it is desirable to provide one kind is able to achieve more
The device for revolving and driving that high reduction ratio, more low speed export.
Planet combined type device for revolving and driving described in the utility model, including pedestal, pivoting support, worm screw, the base
Seat is made of axle housing and two part of seat ring, and the axial line of axle housing and the axial line of seat ring are orthogonal on spatial position, described
Worm screw is mounted in the axle housing of pedestal, and the pivoting support includes inner ring, outer ring and the rolling between inner ring and outer ring
Pearl, pivoting support are mounted in the seat ring of pedestal, characterized in that are additionally provided with planetary reduction unit in the input terminal of worm screw, institute
Stating planetary reduction unit includes gear ring and several grades of central gears, planetary gear and the planet carrier that are arranged in gear ring.
In above-mentioned technical proposal, the output end of pivoting support can be inner ring, be also possible to outer ring, pivoting support it is defeated
It goes too far and is equipped with tooth, and the tooth engagement with worm screw.
More preferred, central gear, planetary gear and planet carrier in the gear ring of the planetary reduction unit are two-stage
Or three-level.
More preferred, the input terminal end face circumferencial direction of worm screw is uniformly arranged several pin holes, the quantity of pin hole and last
The quantity of primary planet pinion is identical, and planetary gear is mounted in pin hole.
In technical solution described in the utility model, the output shaft of driving device and the central gear of first order planetary reduction gear
Connection, the planet carrier of the first order is connected with the central gear of the second level, and so on, the planet carrier of afterbody planetary reduction gear and
The input terminal of worm screw connects, and the high speed rotation output of such driving device is filled by revolution again after the deceleration of multistage planet deceleration unit
It sets low speed after being slowed down to export, to realize bigger reduction ratio.
Meanwhile for the miniaturization of more realization device, also by the gear ring of multistage planet deceleration mechanism in the utility model
It is designed as an entirety, and the planetary gear of afterbody is directly installed on to the input quotient of worm screw, utilizes the input terminal of worm screw
As the planet carrier of afterbody planetary reduction gear, to more save the amount of parts of the present apparatus.
The utility model organically ties multistage planet deceleration mechanism and device for revolving and driving together, has both realized very high
Reduction ratio, high output torque, and remain the advantages that device for revolving and driving bearing capacity is big, anchorage is strong.Meanwhile also having
Compact-sized, the advantages that integrated level is high, greatly improves the reliability of product, the manufacture for reducing product, maintenance cost.
