Abstract
The utility model relates to an internally-meshed gear structure for a corn harvester. The internally-meshed gear structure comprises a big gear and a pinion, wherein the pinion is meshed in the big gear; and each of pressure angles Alpha of the big gear and the pinion is selected as 22-25 degrees. The internally-meshed gear structure has the benefits that the bearing capacity of the corn harvester can be effectively improved, the structural design is scientific and reasonable, and the meshing is more stable.
Description
Technical field
The utility model belongs to field of gears, and especially a kind of corn picker is used the inside engaged gear structure.
Background technology
In the prior art; Comprise gear wheel and pinion in the corn picker inside engaged gear structure; Pinion mate in the gear wheel, but the pinion undercut is serious, and effectively involute profile is short; The relative gear wheel weak strength of pinion has reduced corn picker inside engaged gear structure bearing capacity.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of corn picker to use the inside engaged gear structure, and this inside engaged gear structure can effectively improve the corn picker bearing capacity, and scientific structure design is reasonable, engagement is more firm.
The utility model solves its technical problem and realizes through following technical scheme:
A kind of corn picker is used the inside engaged gear structure, comprises gear wheel and pinion, pinion mate in the gear wheel, and the pressure angle α of its gear wheel and pinion all selects the degree into 22-25 for use.
And it is 22.5 degree that the pressure angle optimum of described gear wheel and pinion is all selected for use.
Advantage of the utility model and beneficial effect are:
This corn picker is used the inside engaged gear structure; Comprise gear wheel and pinion, pinion mate in the gear wheel, the pressure angle α of its gear wheel and pinion all selects the degree into 22-25 for use; Can effectively improve the corn picker bearing capacity, scientific structure design is reasonable, engagement is more firm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of corn picker is used the inside engaged gear structure, comprises gear wheel 1 and pinion 2, pinion mate in the gear wheel, and the pressure angle α of its gear wheel and pinion all selects the degree into 22-25 for use, and it is 22.5 degree that the pressure angle optimum of gear wheel and pinion is all selected for use.
In the utility model, power is delivered to pinion through gearbox, reaches the deceleration purpose through pinion and gear wheel engagement.After adopting the pressure angle correction, the canine tooth gear teeth are long to be 35mm, and pinion gear teeth is long to be 45mm; Thereby increase the flexural strength of pinion shaft, the big than before 2mm of pinion its thickness at root of tooth after angle modification, the big 2mm of the more former pinion gear teeth of pinion gear teeth portion cylindrical portion's cylindrical; Therefore the pinion bearing capacity improves 20%, the long 15mm that increases of pinion gear teeth, and its bearing capacity improves 50%; Long its bearing capacity of the 7mm. of increasing of the canine tooth gear teeth increases by 20%, and after the big or small form of gear tooth correction, the integrated carrying ability all increases; Make engagement more firm, subtract gear rapid wear phenomenon thereby solve the limit.
Claims (2)
1. a corn picker is used the inside engaged gear structure, comprises gear wheel and pinion, pinion mate in the gear wheel, and it is characterized in that: the pressure angle α of gear wheel and pinion all selects the degree into 22-25 for use.
2. corn picker according to claim 1 is used the inside engaged gear structure, it is characterized in that: it is 22.5 degree that the pressure angle optimum of described gear wheel and pinion is all selected for use.
