Abstract
The utility model discloses an embroidery machine servo drive backlash-free gear transmission case which comprises a motor, a gear, a case body and adjusting blocks. The motor is connected to one end of a cube body, the other end of the cube body is connected with the case body, a driving gear shaft and a driven gear shaft are respectively arranged in the case body, one end of the driving gear shaft is connected with the motor through a connecting shaft sleeve, a driving gear is arranged at the other end of the driving gear shaft, a first driven gear and a second driven gear are arranged at the two ends of the driven gear shaft respectively, the first driven gear and the second driven gear are meshed with the driving gear, and the four adjusting blocks are arranged beside the first driven gear and the second driven gear. The embroidery machine servo drive backlash-free gear transmission case is simple in structure, gear matching transmission is free of a gear backlash, and the advantages of being high in transmission precision and small in rotating damping torque are achieved.
Description
Technical field
The utility model relates to a kind of transmission case, specifically embroidery machine servo-drive anti-backlash gear transmission case.
Background technique
Existing embroidery machine servo-drive transmission case generally all adopts toothed belt transmission, its shortcoming is in toothed belt transmission, to require to have certain tension force, its tension force crosses that I haven't seen you for ages affects transmission accuracy, and its overtension can produce very large damping torque, also can make the life-span of Timing Belt too short.Now also do not find and neither affect transmission accuracy, do not make again the short and large equinoctial point of damping torque of Timing Belt life-span.
Summary of the invention
The purpose of this utility model is to design a kind of embroidery machine servo-drive anti-backlash gear transmission case.
The utility model mainly designs a kind of embroidery machine servo-drive anti-backlash gear transmission case, to overcome above the deficiencies in the prior art.
The technical solution of the utility model is: comprise motor, gear, casing and adjustment block, body one end, the described motor side of being connected in, side's body the other end is connected with casing, in described casing, be respectively equipped with driving gear shaft and passive tooth wheel shaft, described driving gear shaft one end is overlapped with motor and is connected by connecting shaft, the other end is provided with driving gear, described passive tooth wheel shaft two ends are respectively equipped with the first driven gear and the second driven gear, described the first driven gear and the second driven gear are meshed with driving gear, the described first do not move gear and the second driven gear side is provided with four adjustment blocks.
Described casing upper end is provided with case lid.
Described casing side is provided with connecting body.
The beneficial effects of the utility model are: by designing a kind of anti-backlash gear transmission case, actuating motor is connected to driving gear, driving gear is meshed with two driven gears, adjusts the phase angle of two driven gears by adjustment block, has eliminated the gap of three gears.The utility model is simple in structure, and gear coordinates transmission gearless gap, has advantages of higher transmission accuracy and less rotary damping moment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: motor of the present utility model 2 side's of being connected in body 4 one end, side's body 4 the other ends are connected with casing 11, in described casing 11, be respectively equipped with driving gear shaft 10 and passive tooth wheel shaft 7, described driving gear shaft 10 one end are overlapped 1 by connecting shaft and are connected with motor 2, the other end is provided with driving gear 9, described passive tooth wheel shaft 7 two ends are respectively equipped with the first driven gear 3 and the second driven gear 8, described the first driven gear 3 and the second driven gear 8 are meshed with driving gear 9, the described first do not move gear 3 and the second driven gear 8 sides are provided with four adjustment blocks 6, described casing 11 upper ends are provided with case lid 5, described casing 11 sides are provided with connecting body 12.
The utility model, by a kind of anti-backlash gear transmission case of design, connects driving gear 9 by motor 2, then designs two driven gears, is meshed with driving gear, and driving gear is synchronously by transmission of power to two driven gear; Because gear transmission has backlash, adjust the phase angle of two driven gears by adjustment block, make the profile of tooth of two driven gears certain angle that staggers, the gap of so just eliminating three gears, has reached the object without the transmission of backlash highi degree of accuracy.
