Background technique
The rack pinion for going for relatively long distance usually requires multiple rack gears mutually to be spliced use, existing tooth
Item splicing installation is to be spliced two sections of rack gears by tooth engagement by tooth plate by one rack type of processing, this mode needs pre-
First process corresponding modulus by tooth plate, in splicing, it is also necessary to adjust backlash, when use is very inconvenient, while when two rooted teeth
The case where item also occurs that dislocation when receiving external force needs to be fixed from newly.
Ensure stitching portion as disclosed in document 201020149050.3 and when a kind of rack splicing is installed in the prior art
Space width and the consistent device of rack gear.Adaptable, spacing is consistent with space width on rack gear between can ensure that the rack gear being spliced.But
It is that the rack gear that device adjusting backlash need to splice every two be adjusted separately, if the quantity of rack splicing is larger, work
Amount also increases with it, and brings to rack splicing constant, while there is also unsteady to the fixation device of the rack gear spliced
Defect will also do over again again if will cause dislocation between the larger rack gear of the external force being subject to.
Summary of the invention
In view of the above-mentioned problems, the utility model, which provides one kind, need not carry out backlash adjustment, and the rack gear of fixation
Splicing construction, specific structure is as follows:
A kind of splicing construction of rack gear, including rack gear fixing groove have been sequentially inserted into more toothed racks in the rack gear fixing groove,
The rack gear is located at the slot offered below the flank of tooth along the setting of rack gear length direction, and the slot is distinguished at the both ends of rack gear
Offer opening, inserted with plate in the slot, the length of the plate is greater than the sum of more toothed rack length, when rack gear is fixed
When in slot inserted with more toothed racks, the plate passes through the slot of every toothed rack, the flank of tooth setting of one end of the every rack gear
The flank of tooth for concave surface, the other end is set as convex surface, when the splicing of two toothed racks, wherein the concave ends of a toothed rack and another tooth
The convex surface end of item is adjacent.
Further, multiple plate fixation holes are offered on the plate, offer multiple rack gears on the concave surface of the flank of tooth
Perforation, the rack gear perforation are through to the bottom of rack gear, and the slot bottom of the rack gear fixing groove is equipped with multiple slot fixation holes, the slot
Fixation hole, rack gear perforation and plate fixation hole three aperture having the same, slot fixation hole, rack gear perforation and plate fixation hole
Between be fixed by bolt.
Further, the two sides of the rack gear fixing groove offer side slot respectively, and the two sides of the rack gear are respectively equipped with grafting
Side plate in the slot of side.
Further, the rack gear fixing groove is hard rubber material.
Further, the slot fixation hole is through to the slot bottom of rack gear fixing groove, the fixation hole on slot fixation hole and tooling platform
To matching.
Compared to the prior art compared with the utility model has the advantage that as follows:
1, the utility model makes muti-piece rack gear automatic aligning in the longitudinal direction by rack gear fixing groove, and will not be outside receiving
It misplaces after power；
2, the utility model further avoids the dislocation after rack gear stress by being inserted into plate in multiple rack gears；
3, the utility model saves the later period to two by the way that the convex surface end of two adjacent rack gears and concave ends are connected to each other
The adjustment work of backlash, effectively improves working efficiency between a rack gear.
