Abstract
The utility model discloses a flexible clearance eliminator of gear and gear rack, for eliminating the clearances between meshed gears and a gear rack. The utility model comprises a gear rack (6) and two gears (5, 7) meshed with the gear rack (6). The utility model is characterized in that the gear (5) is connected with the output shaft of a speed reducer (4), the gear (7) is connected with the output shaft of a speed reducer (2), and a flexible coupler (3) is mounted between the output shaft of the speed reducer (2) and the input shaft of the speed reducer (4). The utility model can realize same clearance between different gears and one gear rack and uniformly drive gear rack.
Description
Technical field
The utility model relates to a kind of flexible backlash eliminating equipment of gear rack, the different gap that produces when being used to eliminate different gears and being meshed with same tooth bar.
Background technique
Rack and pinion drive is one of prevailing kind of drive in the mechanical transmission, tooth bar transmission for the big power of needs, same tooth bar can be meshed with a plurality of driving gears, each driving gear all joins with drive unit, the device of this structure after the installation or after operation a period of time, can produce different gaps between each driving tooth wheel and rack, can not make the even simultaneously and tooth bar engagement of each driving gear
Summary of the invention
The purpose of this utility model provides the flexible backlash eliminating equipment that has identical gap between a kind of each gear and the same tooth bar, can evenly drive tooth bar simultaneously, overcomes the deficiencies in the prior art.
The flexible backlash eliminating equipment of gear rack of the present utility model, it comprises tooth bar 6 and the gear 5 that is meshed with tooth bar 6, gear 7, it is characterized in that: described gear 5 joins with the output shaft of retarder 4, gear 7 joins with the output shaft of retarder 2, between the input shaft of the output shaft of retarder 2 and retarder 4 flexible coupling 3 is installed.
The flexible backlash eliminating equipment of gear rack of the present utility model, since be provided with flexible coupling between the gear that tooth bar is meshed, this coupling has the adjustment function, can make between each gear and the same tooth bar to have identical gap, equably tooth bar is driven simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in the figure: 6 is tooth bar, and gear 5 and gear 7 all descend tooth bar 6 to be meshed, and drives the tooth bar action as driving gear simultaneously.Gear 5 joins with the output shaft of retarder 4, gear 7 is direct with the output shaft of retarder 2, between the input shaft of another output shaft of retarder 2 and retarder 4, flexible coupling 3 is housed, the standard piece of flexible coupling 3 for selecting for use, the size according to transferring power when selecting for use is determined.During installation, each retarder can be fixedly connected on the support, the input shaft 1 and the drive motor of retarder 2 join, and can guarantee that each gear all has identical gap with tooth bar 6, evenly drive the tooth bar action simultaneously.
Claims (1)
1, a kind of flexible backlash eliminating equipment of gear rack, it comprises tooth bar (6) and the gear (5) that is meshed with tooth bar (6), gear (7), it is characterized in that: described gear (5) joins with the output shaft of retarder (4), gear (7) joins with the output shaft of retarder (2), between the input shaft of the output shaft of retarder (2) and retarder (4) flexible coupling (3) is installed.
