The gear-driven rotary mechanism is high in precision of rotary movement transmission, good in stability, and suitable for a long-time rotary processing.
Description
Technical field
The utility model relates to a kind of gear drive rotating machinery, is specially adapted to the rotating machinery of machining center yaw and turntable.
Background technique
Existing mechanical type rotating mechanism mainly contains following two kinds of structures:
1, adopt actuating motor to drive the structural type of worm and gear rotation, this kind is simple in structure, implements easily, but Worm Wheel System efficient is low, wears no resistance, and makes the rotating machinery low-response, precision stability is poor, can be used for indexing mechanism, but is not suitable for long-time rotation processing.
2, actuating motor drives one group of gear-driven structural type, this kind structure is more commonly used, but because gear-driven limitation, two meshed gears always have a side to have inter-lobe clearance, when driving gear need to be done forward and reverse rotation motion, inter-lobe clearance can reduce the precision and stability that transmits rotation.
The model utility content
The purpose of this utility model is the above-mentioned deficiency for prior art, and a kind of gear drive rotating machinery is provided, and the precision that it has transferring rotational motion is high, the advantage of good stability, is applicable to for a long time rotation processing.
For achieving the above object, gear drive rotating machinery of the present utility model, comprise main drive gear, driven gear, characterized by further comprising the two center tooth axles that are positioned at the main drive gear both sides, be equipped with one-level intermediate gear and secondary intermediate gear on the center tooth axle, the forward working flank of main drive gear is meshed with the forward working flank of the one-level intermediate gear of a side, is meshed with the reverse operation flank of tooth of driven gear with the reverse operation flank of tooth of the coaxial secondary intermediate gear of this one-level intermediate gear; The reverse operation flank of tooth of main drive gear is meshed with the reverse operation flank of tooth of the one-level intermediate gear of opposite side, is meshed with the forward working flank of driven gear with the forward working flank of the coaxial secondary intermediate gear of this one-level intermediate gear.
When the utility model turned clockwise with gear, each tooth the preceding that flank of tooth was the forward working flank, otherwise then was the reverse operation flank of tooth; When main drive gear turns clockwise, the forward working flank of main drive gear is meshed with the forward working flank of the one-level intermediate gear of a side, drive this one-level intermediate gear and coaxial secondary intermediate gear is rotated counterclockwise, the reverse operation flank of tooth of coaxial secondary intermediate gear and the reverse operation flank engagement of driven gear drive driven gear and turn clockwise; When main drive gear is rotated counterclockwise, the reverse operation flank of tooth of main drive gear is meshed with the reverse operation flank of tooth of the one-level intermediate gear of opposite side, drive this one-level intermediate gear and coaxial secondary intermediate gear turns clockwise, the forward working flank of coaxial secondary intermediate gear and the engagement of the forward working flank of driven gear drive driven gear and are rotated counterclockwise;
When the positive and negative rotation of above-mentioned main drive gear, by meshing the opposite flank of tooth with two groups of intermediate gears, eliminated gear-driven gap, the precision that the utlity model has transferring rotational motion is high, the advantage of good stability, is applicable to for a long time rotation processing.
Description of drawings
Fig. 1 is the utility model embodiment's stereogram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, for ease of difference, when turning clockwise with gear, each tooth the preceding that flank of tooth is the forward working flank, otherwise then is the reverse operation flank of tooth.
By shown in Figure 1, this gear drive rotating machinery, comprise main drive gear 1, be positioned at two center tooth axles 2 and 3, the driven gear 4 of main drive gear 1 both sides, 2 are provided with one-level intermediate gear 5 and secondary intermediate gear 6 on the center tooth axle in left side, 3 are provided with one-level intermediate gear 7 and secondary intermediate gear 8 on the center tooth axle on right side, the forward working flank of main drive gear 1 is meshed with the forward working flank of one-level intermediate gear 5, is meshed with the reverse operation flank of tooth of driven gear 4 with the reverse operation flank of tooth of the coaxial secondary intermediate gear 6 of one-level intermediate gear 5; The reverse operation flank of tooth of main drive gear 1 is meshed with the reverse operation flank of tooth of one-level intermediate gear 7, is meshed with the forward working flank of driven gear 4 with the forward working flank of the coaxial secondary intermediate gear 8 of one-level intermediate gear 7.
When main drive gear 1 turns clockwise, the forward working flank of main drive gear 1 is meshed with the forward working flank of one-level intermediate gear 5, driving one-level intermediate gear 5 and coaxial secondary intermediate gear 6 is rotated counterclockwise, the reverse operation flank of tooth of secondary intermediate gear 6 and the reverse operation flank engagement of driven gear 4, drive driven gear 4 and turn clockwise, this moment, one-level intermediate gear 7 and secondary intermediate gear 8 were made servo rotary; When main drive gear 1 is rotated counterclockwise, the reverse operation flank of tooth of main drive gear 1 is meshed with the reverse operation flank of tooth of one-level intermediate gear 7, driving one-level intermediate gear 7 and coaxial secondary intermediate gear 8 turns clockwise, the forward working flank of coaxial secondary intermediate gear 8 and the engagement of the forward working flank of driven gear 4, drive driven gear 4 and be rotated counterclockwise, this moment, one-level intermediate gear 5 and secondary intermediate gear 6 were made servo rotary;
Because during main drive gear 1 positive and negative rotation, drive driven gear 4 by meshing the opposite flank of tooth with two groups of intermediate gears, eliminated gear-driven gap, the precision that the utlity model has transferring rotational motion is high, the advantage of good stability, is applicable to for a long time rotation processing.
