And, in situation about being consisted of by two gears like this, because above-mentioned top connection gear is connected gear and can be made of the gear of the number of teeth that differs from one another with the bottom, therefore have the advantage of the speed reducing ratio that can realize various transmission according to characteristic and the machining object of lathe, can also be consisted of by various gears as required.
For example, the 1st connection teeth wheel unit (200) can connect gear (210) and the 1st worm gear (220) formation by the 1st of coaxial connection, the 2nd connection teeth wheel unit (300) can connect gear (310) and the 2nd worm gear (320) formation by the 2nd of coaxial connection, the the above-mentioned the 1st and the 2nd connects gear (210) (310) can contact with worktable rotary gear (110), and the above-mentioned the 1st can be connected with driven wheel (400) (500) respectively with the 2nd worm gear (220) (320).
At this moment, the the above-mentioned the 1st and the 2nd driven wheel (400) (500) drives worm screw (410) and the 2nd by the 1st and drives worm screw (510) formation, contact with the 2nd worm gear (320) with above-mentioned the 1st worm gear (220), thereby can make the 1st and the 2nd worm gear (220) (320) rotation, be connected gear (210) (310) rotation with the 2nd and above-mentioned worktable rotary gear (110) is rotated with the 1st of the coaxial combination of the 2nd worm gear (220) (320) with the above-mentioned the 1st respectively.
Its result, the above-mentioned the 1st connects gear (210) by the 1st of axle connection respectively with the 2nd connection teeth wheel unit (200) (300), and and the 1st worm gear (220) and the 2nd connects gear (310) and the 2nd worm gear (320) consists of, can make the above-mentioned the 1st and the 2nd connection gear (210) (310) different with the number of teeth of the 2nd worm gear (220) (320) with the 1st, realize the speed reducing ratio of various transmission.
In addition, about above-mentioned the 1st driven wheel (400) and the 2nd driven wheel (500), possess the above-mentioned the 1st at the one end and drive worm screw (410) and the 2nd driving worm screw (510), form the 1st drive pulley (420) and the 2nd drive pulley (520) at the other end, consist of thus two shape shafts, drive motors (600) is to connect by the connecting elements as rotating band (610) to obtain the power that transmits with the 1st with the 2nd drive pulley (420) (520), according to the direction of rotation of above-mentioned drive motors (600) and towards each other identical direction rotation.
As mentioned above, above-mentioned the 1st connection teeth wheel unit (200) will be connected with worktable rotary gear (110) with the 2nd connection teeth wheel unit (300) and to same direction rotation, can be the rotation of workbench (100) be produced and disturbs, therefore above-mentioned the 1st driven wheel (400) and the 2nd driven wheel (500) be with above-mentioned the 1st connection teeth wheel unit (200) be connected the mode of the 2nd connection teeth wheel unit (300) to same direction rotation and connect.
For example, when above-mentioned the 1st driven wheel (400) and the 2nd driven wheel (500) drive worm screw (410) (420) and consist of by the 1st and the 2nd, constitute respectively dextrorotation nail and left-handed screw, make thus above-mentioned the 1st connection gear (210) and the 2nd connect gear (320) to same direction rotation.
Below, the using method of the workbench rotating device of the lathe of detailed description one embodiment of the invention.
With reference to Fig. 5, be appreciated that following example: the driving force that produces at drive motors (600) is delivered to the 1st and the 2nd connection teeth wheel unit (200) (300) and finally drives worktable rotary gear (110) by the 1st and the 2nd driven wheel (400) (500).
Fig. 5 (a) illustrates and makes above-mentioned workbench (100) to right handed example, when the 1st drives worm screw (410) by the connecting elements as rotating band (610) and above-mentioned drive motors (600) interlock and to clockwise direction and rotates, the 1st worm gear (220) of coaxial connection and the 1st connects gear (210) to counterclockwise rotation, and then makes worktable rotary gear (110) to clockwise rotation.
In addition, the 2nd connection gear (310) that is connected with the opposite side of above-mentioned worktable rotary gear (110) is also to counterclockwise rotation, consist of in the mode to the direction rotation identical with above-mentioned the 1st driving worm screw (410) with coaxial the 2nd driving worm screw (510) that is connected in the 2nd worm gear (320) interlock of above-mentioned the 2nd connection gear (310), therefore can successfully realize the rotation of above-mentioned workbench (100) by interference-free.
Equally, Fig. 5 (b) illustrates and makes above-mentioned workbench (100) to the example that counterclockwise rotates, when the above-mentioned the 1st drive worm screw (410) and above-mentioned the 2nd driving worm screw (510) by as with connecting elements and above-mentioned drive motors (600) interlock and when rotating to counter clockwise direction, the above-mentioned the 1st connects gear (210) and the 2nd connects gear (310) to clockwise rotation, and then makes worktable rotary gear (110) to counterclockwise rotation.
And, the the above-mentioned the 1st and the 2nd drives worm screw (410) (510) carries out work as independent driving shaft independently according to the direction of rotation of workbench, thereby the 1st drives the motion on worm screw (410) the imputability clockwise direction, the 2nd drives the motion on worm screw (510) the imputability counter clockwise direction, owing to identical direction rotation, therefore can carry out work as driving shaft simultaneously according to the direction of rotation of workbench.
With reference to Fig. 6, be appreciated that and adjust the example that the above-mentioned the 1st and the 2nd driven wheel (400) (500) reduces back clearance.
When in a clockwise direction to above-mentioned the 1st driven wheel (400) when applying power, connect airtight in the gear of the 1st connection gear (210) and the seamless unoccupied place of gear of worktable rotary gear (110), simultaneously when with counterclockwise to above-mentioned the 2nd driven wheel (500) when applying power, the gear of above-mentioned the 2nd connection gear (310) and the gear of worktable rotary gear (110) connect airtight, and connect gears consist of closed loop (Closed loop) by a worktable rotary gear effect thereby produce on the whole two.
Therefore, when carrying out the rotatablely moving of workbench under this state, produce the effect that back clearance significantly reduces, aforesaid back clearance methods to reduce noises generally can suitably be used by manual operation when needed by the user.
In addition, as mentioned above, make up the back clearance adjustment modes that round about each driven wheel (400) (500) is applied power with drive member independently, thereby can make the user carry out this pattern.
More than, although with reference to the accompanying drawings of embodiments of the invention, those skilled in the art on the basis of not changing technological thought of the present invention or essential feature, can implement in other concrete modes as can be known.
Therefore, the embodiment that is interpreted as above narration is illustrative on all faces rather than limits, scope of the present invention embodies above-mentioned particular content by claim, should be interpreted as all changes of deriving from the meaning of claim and scope and equivalent concepts thereof or the mode of distortion and be included in scope of the present invention.
Industrial utilizability
The workbench rotating device of the lathe of the present invention that consists of as mentioned above, to directly be constituted as the structure of output by a gear on worm in the past, output is divided into two connection teeth wheel units of both sides, thereby can reduces the abrasion that the use by gear on worm causes.
In addition, adjust easily back clearance owing to can regulate both sides connection teeth wheel unit, therefore facilitate to the user, can improve the precision that adds man-hour.
And, the worktable rotary output in the past that can be enough general spur gear or helical gear replace the gear on worm by double lead to consist of, thus the advantage that can reduce cost of manufacture had.
