Abstract
The utility model discloses a duplicate gear of an electric forklift reducer. The duplicate gear of the electric forklift reducer comprises large teeth and small teeth which are arranged separately, wherein the large teeth and the small teeth rotate synchronously. According to the duplicate gear of the electric forklift reducer, the large teeth and the small teeth are arranged separately, after being machined respectively, the large teeth and the small teeth are assembled together in a synchronous rotation manner, so that the defect that the processing properties of conventional integrated duplicate gear of the electric forklift reducer are poor is effectively overcome, the manufacturing precision and the production efficiency of the gear are favorably improved, and the manufacturing costs are reduced.
Description
Technical field
The utility model relates to a kind of gear, and concrete is a kind of duplicate gear that is used on the electri forklift retarder.
Background technique
As shown in Figure 1, be prior electric fork truck retarder duplicate gear structural representation.Prior electric fork truck retarder duplicate gear all adopts integrated type; And the large and small end tooth of electri forklift retarder duplicate gear is helical gear; Can interfere because of big end tooth and can't adopt the little end tooth of gear hobbing processes; Can only adopt gear shaping technology, and adopt the manufacturability of the little end tooth of gear shaping skilled worker bad, gear shaping is compared with gear hobbing has remarkable shortcoming:
(1) total cumulative pitch error is bigger, and follow-up fine finishing (shaving) can't be eliminated total cumulative pitch error, makes that the small end tooth precision finally be processed into behind the finished product is relatively poor;
(2) in order to insert the small end helical gear, common gear shaping machine need be pulled down straight guide, installs special-purpose helical guideway additional, and helical guideway must could design and make after the gear shaper cutter number of teeth is confirmed, the cycle is longer, and cost is higher;
(3) manufacturing efficiency is low, and cost is high.
In view of this, the utility model is intended to prior electric fork truck retarder duplicate gear structure is improved, so that obtain the better electri forklift retarder of a kind of performance of technical process duplicate gear.
Summary of the invention
The technical problem that the utility model will solve is to propose a kind of electri forklift retarder duplicate gear, and the performance of technical process of this electri forklift retarder duplicate gear is better, can effectively improve its processing cost of its machining accuracy, efficient and reduction.
Realize above-mentioned technical purpose, the electri forklift retarder duplicate gear of the utility model comprises being big end tooth and the little end tooth that split is provided with that said big end tooth and little end tooth rotate synchronously.
Further, said big end tooth is sleeved in the rotating shaft of little end tooth, and the rotating shaft of little end tooth is provided with and is used for the spacing shaft shoulder of big end tooth;
Further, the rotating shaft interference fit of said big end tooth and little end tooth;
Further, the rotating shaft of said big end tooth and little end tooth is welded to connect;
Further, the rotating shaft of said big end tooth and little end tooth is connected through spline.
The beneficial effect of the utility model is:
The electri forklift retarder duplicate gear of the utility model is through being provided with big end tooth and the split of small end tooth; After can adopting gear hobbing technology to process big end tooth and small end tooth respectively respectively; Again big end tooth and little end tooth are assembled together synchronously rotationally; Effectively solved the defective of existing integral electric fork truck retarder duplicate gear technology capability difference, helped improving gear accuracy of manufacturing and manufacturing efficiency and reduce manufacture cost.

The electri forklift retarder duplicate gear of present embodiment passes through big end tooth 1 and the 2 split settings of small end tooth; After can adopting gear hobbing technology to process big end tooth 1 and small end tooth 2 respectively respectively; Again big end tooth 1 is assembled together with small end tooth 2 synchronously rotationally; Effectively solved the defective of existing integral electric fork truck retarder duplicate gear technology capability difference, helped improving gear accuracy of manufacturing and manufacturing efficiency and reduce manufacture cost.
As shown in Figure 3, be the utility model electri forklift retarder duplicate gear second embodiment's structural representation.The big end tooth 1 of present embodiment is welded to connect with the rotating shaft 3 of small end tooth 2, realizes the synchronous rotation between big end tooth 1 and the small end tooth 2.
Other structures of present embodiment are identical with first embodiment, no longer tired stating.
Shown in Figure 4, be the utility model electri forklift retarder duplicate gear the 3rd embodiment's structural representation.The big end tooth 1 of present embodiment and the rotating shaft of small end tooth 23 are connected through spline, realize the synchronous rotation between big end tooth 1 and the small end tooth 2.
Other structures of present embodiment are identical with first embodiment, not tired stating one by one.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
