Description
Technical field
A kind of side dual-drive precise positioning transmission device is the utility model is related to, is widely used in various transmission mechanisms, especially
It is the transmission mechanism of solar light-heat power-generation tracking system.
Background technology
At present, in the tracking system angle of pitch transmission of solar light-heat power-generation, a large amount of lists for using pivoting support structure
Worm-drive decelerator, its advantage are that gearratio is big, stable drive, can be born axial force, radial load with self-locking and be tumbled
Torque.Shortcoming is：1st, worm and gear precision do it is how high can all have back lash, otherwise can occur stuck can not turn
It is dynamic, also processing cost also can be very big when precision is too high, thus solar energy eyeglass is easily rocked due to back lash, influences to send out
Electrical efficiency；2nd, in the elevating movement of solar energy eyeglass, due in the presence of gravity and wind-force, it is necessary to which very big rotation is turned round
Square, and single worm-drive tends not to meet needs.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of side dual-drive for above-mentioned prior art precisely to determine
Position transmission device, it can eliminate gap precise positioning on the premise of worm and gear machining accuracy processing cost is not improved, improve
Tracking accuracy；Simultaneously because twin worm is designed, it is possible to achieve Large-torsion transmisson；Twin worm homonymy is set, and makes compact-sized, convenience
The arrangement of solar energy eyeglass.
The technical scheme in the invention for solving the above technical problem is：A kind of side dual-drive precise positioning transmission dress
Put, it includes pedestal, and bearing is provided with swiveling gear in the pedestal, and left and right is arranged with the in parallel on the swiveling gear
One gear ring and the second gear ring, swiveling gear lower section left and right are arranged with the first worm screw and the second worm screw, first snail in parallel
Bar and the second worm screw are meshed with the first gear ring and the second gear ring respectively, and the first motor and the second electricity are provided with the outside of the pedestal
Machine, first motor and the second motor drive the first worm screw and the second worm screw respectively.
It is plane at left and right sides of the swiveling gear, screw is offered on the side of left and right two of the swiveling gear.
Compared with prior art, the utility model has the advantage of：
A kind of side dual-drive precise positioning transmission device of the utility model, it can add not improving worm and gear machining accuracy
On the premise of work cost, gap precise positioning is eliminated, improves tracking accuracy；Simultaneously because twin worm is designed, it is possible to achieve big to turn round
Square is driven；Twin worm homonymy is set, and makes compact-sized, facilitates the arrangement of solar energy eyeglass.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Fig. 1 ~ Fig. 3, a kind of side dual-drive precise positioning transmission device in the present embodiment, it includes pedestal 1, institute
State in pedestal 1 and swiveling gear 2 is provided with by bearing, left and right is arranged with the first gear ring 3 and second in parallel on the swiveling gear 2
Gear ring 4, the lower section of swiveling gear 2 left and right are arranged with the first worm screw 5 and the second worm screw 6, first worm screw 5 and second in parallel
Worm screw 6 is meshed with the first gear ring 3 and the second gear ring 4 respectively, and the outside of pedestal 1 is provided with the first motor 7 and the second motor
8, the motor 8 of the first motor 7 and second drives the first worm screw 5 and the second worm screw 6 respectively；
The left and right sides of swiveling gear 2 is plane, and screw work is offered on the side of left and right two of the swiveling gear 2
For output flange.
When system needs swiveling gear to rotate, then two equidirectional rotations of motor, make two worm screw synchronization outputs, realize
Big driving torque output, when system needs to stop positioning, then the first motor stalls, the second motor are indicated by electric-control system
Short time antiport, the left flank of the first worm screw, the right tooth flank of the second worm screw is set to be contacted respectively with the flank of gear,
So as to realize precise positioning.
In addition to the implementation, the utility model also includes other embodiment, all to use equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within the protection domain of the utility model claims.
