The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1,
As shown in Figure 1, a kind of lathe transmission device comprises:
Retreat driving gear 2, feeding driving gear 4, driving shaft 3, retreat driven gear 5, feeding driven gear 7 and driven axle 6, describedly retreat driving gear 2 and feeding driving gear 4 coaxial being connected on the driving shaft 3, described driving shaft 3 is in transmission connection with the dynamical system 1 of described lathe;
Describedly retreat driven gear 5 and feeding driven gear 7 coaxial being connected on the driven axle 6, described driven axle 6 is in transmission connection with the actuating unit 8 of described lathe;
Described retreat driving gear 2, feeding driving gear 4 and describedly retreat driven gear 5, feeding driven gear 7 is corresponding respectively is in transmission connection;
Described driving gear 2 and the feeding driving gear 4 of retreating is respectively equipped with a direction and follows driving shaft 3 and rotate the unidirectional transmission that another directions are then freely rotated around driving shaft 3 synchronously, and described two non-return devices are opposite with the servo-actuated direction of driving shaft 3; Described retreat driving gear 2, feeding driving gear 4 and describedly retreat driven gear 5, the corresponding respectively coupling of feeding driven gear 7 is connected with a joggle; Described unidirectional transmission is that a direction is followed the unilateral bearing that driving shaft 3 synchronous another directions of rotation are then freely rotated around driving shaft 3.Fixedly connected with described driven axle 6 with feeding driven gear 7 and retreat driven gear 5.
Its operation principle is, when retreating, start dynamical system 1, it drives driving shaft 3 and rotates, driving shaft 3 drives and retreats driving gear 2 rotations, driving gear 2 drives and retreats driven gear 5 rotations, retreat driving gear 5 and drive driven axle 6 rotations, driven axle 6 drives lathe actuating unit 8 and retreats fast, and feeding this moment driven gear 7 also rotates along with driven axle 6, and it drives feeding driving gear 4 and rotates, because the existence of unidirectional transmission, feeding this moment driving gear 4 rotates freely around driving shaft 3, and does not have the transmission of moment and energy, is equivalent to the gear relevant with feeding and all has neither part nor lot in work.Otherwise, when feeding, dynamical system 1 counter-rotating, drive driving shaft 3 counter-rotatings, this moment feeding driving gear 4 and 7 work of feeding driven gear, drive 8 feedings at a slow speed of lathe actuating unit because the gear ratio of feeding driving gear 4 and described feeding driven gear 7 less than retreat driving gear 2 and retreat driven gear 5 gear ratio, therefore realized that astern speed is greater than feed speed.
