Abstract
The utility model discloses a speed-changer counter shaft press-loading fixation structure which comprises a plurality of gear wheels and a counter shaft, and is characterized in that the gear wheels and the counter shaft are in interference fit, the gear wheels are connected through welding, and the gear wheel on the outermost is connected with the counter shaft through welding. Adopting the structure, the gear wheels and the counter shaft are integrated while the gear wheels and the counter shaft are made individually, the gear wheels and the counter shaft are relatively connected through keys without increasing procedures, and the speed-changer counter shaft press-loading fixation structure has better intensity and appearance.
Description
Technical field
The utility model belongs to the speed changer field, and particularly a kind of transmission countershaft press-fits fixed structure.
Background technique
Transmission countershaft needs and the gear on it is coupled as one, and just can finish the transmission and the speed changing function of power.Common structure is made gear and jack shaft as a whole, and promptly its blank adopts integral body to forge, and makes through machining again, and its shortcoming is a cast form difficulty relatively, and spillage of material is big, and processing is inconvenient, and final products weight is big; Another method commonly used is to adopt key connecting between jack shaft and the gear, jack shaft and gear adopt and divide body structure, though saved material, because of having increased keyway, correspondingly increased the operation of processing and the also corresponding reduction of join strength of gear and jack shaft.
The model utility content
The purpose of this utility model is the shortcoming at said structure, provides a kind of better transmission countershaft to press-fit fixed structure.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of transmission countershaft press-fits fixed structure, comprises a plurality of gears and jack shaft, it is characterized in that, and between described gear and the jack shaft interference fit, all adopt between the described gear and between outermost gear and the jack shaft to be welded to connect.
The beneficial effects of the utility model are, when keeping gear and jack shaft split production, make gear better become as a whole with jack shaft, and relative key connecting does not increase operation, and has better intensity and outward appearance.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the jack shaft structural representation that adopts structure described in the utility model.
Among the figure:
1, jack shaft; 2,4, gear; 3,5, weld seam.
Embodiment
As shown in Figure 1; it is an a kind of jack shaft that adopts transmission countershaft described in the utility model to press-fit fixed structure; the aperture axis of gear 2 and gear 4 is less than the outer diameter size of jack shaft; adopt oil hydraulic press to apply certain pressure during assembling to gear; it finally is socketed in forms interference fit on the jack shaft; it is as a whole when having guaranteed coaxality gear and jack shaft to be coupled to; for guaranteeing to have better overall; between adjacent gear 2 and gear 4; be installed between the gear 4 and jack shaft in the outside; adopt carbon dioxide gas arc welding to weld, form weld seam 3 and weld seam 5.
Be press-fitted the formation interference fit joint by employing, and further each parts be welded as a whole, key connecting does not increase operation, and has better intensity and outward appearance relatively.
Claims (1)
1, a kind of transmission countershaft press-fits fixed structure, comprises a plurality of gears and jack shaft, it is characterized in that, and between described gear and the jack shaft interference fit, all adopt between the described gear and between outermost gear and the jack shaft to be welded to connect.
