Description
Technical field
The present invention relates to a kind of traverse platform, particularly relate to a kind of driving mechanism of traverse platform.
Background technique
Traverse platform is driven tight meshed gears mechanism to rotate, thus makes the device that table top rotates and workpiece rotates with table top and rotates after referring to and being slowed down by motor high speed rotating and speed reducer.At present, traverse platform on market, the outer ring of its pivoting support respectively with the first actuation gear, second actuation gear is meshed, first actuation gear is by the first motor, first speed reducer drives, second actuation gear is by the second motor, second speed reducer drives, this kind of mode of structure, in use be difficult to guarantee first motor, second motor speed is identical thus be difficult to the synchronous axial system performance of guarantee first actuation gear and the second actuation gear, so just easily there is gear wear phenomenon, thus greatly reduce the working life of gear, add cost of production simultaneously and delay production.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of driving mechanism of traverse platform is provided, guarantee first actuation gear, the second actuation gear synchronous axial system is difficult to the driving mechanism solving existing traverse platform, easily cause gear wear, reduce service life of gear, increase cost of production, delay the problem of production.
The object of the invention is to be achieved through the following technical solutions:
A kind of driving mechanism of traverse platform, comprise motor, first speed reducer and the second speed reducer, described first speed reducer is identical with the speed ratio of the second speed reducer, and one end of the input shaft of the first speed reducer and the rotatingshaft of motor are in transmission connection, the other end of the input shaft of the first speed reducer is in transmission connection by the input shaft of coupling and the second speed reducer, the output shaft of described second speed reducer is provided with the second actuation gear, the output shaft of described first speed reducer is provided with the first actuation gear, described first actuation gear, second actuation gear is all meshed with the outer ring of pivoting support, described pivoting support is connected with traverse platform.
As preferred version of the present invention, described motor is actuating motor.
As preferred version of the present invention, described first speed reducer, the second speed reducer are gear reduction unit.
As preferred version of the present invention, described coupling is diaphragm coupling, have noise low, wear and tear little, accurately can transmit the feature of rotating speed.
Beneficial effect of the present invention is, the driving mechanism structure of described traverse platform is simple, be easy to realize, its speed reducer driving two to be connected by coupling as power source by a motor rotates, thus ensure that the synchronous axial system performance of the first actuation gear and the second actuation gear, solve the problem that actuation gear is easy to wear, improve the working life of actuation gear, virtually reduce cost of production.

Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.Be understandable that, embodiment described herein is only for explaining the present invention, but not limitation of the invention.
Please refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the plan view of the driving mechanism of a kind of traverse platform of the present invention; Fig. 2 is the plan view of the driving mechanism of a kind of traverse platform of the present invention.
In the present embodiment, a kind of driving mechanism of traverse platform, comprise motor 1, first speed reducer 2 and the second speed reducer 3, described motor 1 is actuating motor, described first speed reducer 2, second speed reducer 3 is gear reduction unit, and the first speed reducer 2 is identical with the speed ratio of the second speed reducer 3, the right-hand member of input shaft and the rotatingshaft of motor 1 of described first speed reducer 2 are in transmission connection, the left end of the input shaft of the first speed reducer 2 is in transmission connection by the input shaft of coupling 4 and the second speed reducer 3, described coupling 4 is diaphragm coupling, the output shaft of described second speed reducer 3 is provided with the second actuation gear 6, the output shaft of described first speed reducer 2 is provided with the first actuation gear 5, described first actuation gear 5, second actuation gear 6 is all meshed with the outer ring of pivoting support 7, and the first actuation gear 5, second actuation gear 6 is symmetrically distributed in pivoting support 7 both sides, described pivoting support 7 is connected with traverse platform 8.
During work, motor 1 rotates drive first speed reducer 2 and rotates, the input shaft of the first speed reducer 2 drives the input shaft of the second speed reducer 3 to rotate by coupling 4 simultaneously, thus drive the first actuation gear 5 and the second actuation gear 6 to rotate simultaneously, and then drive the pivoting support 7 be meshed with the first actuation gear 5, second actuation gear 6 to rotate, make the traverse platform 8 be connected with pivoting support 7 with suitable rotational speed; By the net synchronization capability adopting the driving mechanism of above-mentioned traverse platform to substantially increase the first actuation gear 5, second actuation gear 6, add the spreadable life of equipment.
