Description
Technical field
The present invention relates to a kind of rack pinion gap control mechanism, belong to mechanical driving device, for gear-driven clearance control and adjustment.
Background technology
In rack pinion, the gap of meshed transmission gear can affect transmission effect and transmission accuracy.
Summary of the invention
For more preferably realizing control and the elimination of back lash in rack pinion, the present invention provides a kind of oblique tooth type rack pinion gap to eliminate machine
Structure, utilizes the mode of diclinic rack and pinion engagement to eliminate gap, it is achieved continual compensation in transmission process, improves transmission accuracy.
The technical scheme is that the oblique tooth type rack pinion clearance eliminating mechanism for rack pinion, including driving motor, supporting
Plate, driving rack, pin, screw, movable helical gear, fixing helical gear, end cap, expansion sleeve, disk spring, flat key, jump ring.Described consolidates
Determining helical gear to be fastened on driving motor shaft by expansion sleeve, end cap, screw, described movable helical gear is assemblied in fixing helical gear by flat key
On axle journal cylindrical, movable helical gear is oppositely oriented with fixing helical gear gear, is provided with disk spring in the middle of two gears, and described driving rack leads to
Cross screw, sell combined integrated after be assemblied on guide pass, described driving rack is the composite construction that two oppositely oriented monodentate bars are combined into, two
The rotation direction of individual driving rack is consistent with the movable helical gear of engagement and fixing helical gear respectively, and described disk spring is by movable helical gear and fixing helical teeth
Wheel shaft fits tightly with corresponding driving rack to passage, the not ipsilateral of two helical gear teeth, and rack pinion gap eliminates.
During application, driving the gear teeth both sides of the fixing helical gear on motor, movable helical gear combination engaged transmission tooth bar, the tension force of disk spring is more than
The axial force produced during rack pinion, helical gear rack gear tight mesh, gear-driven accuracy is improved.
Accompanying drawing explanation
Accompanying drawing 1 is oblique tooth type rack pinion clearance eliminating mechanism schematic diagram of the present invention.
Detailed description of the invention
Seeing accompanying drawing, the present invention provides a kind of oblique tooth type rack pinion clearance eliminating mechanism, including driving motor 1, support plate 2, driving cog
