Description
Technical field
The utility model relates to a kind of retarder, is specifically related to a kind of planet wheel speed reducer of compact structure.
Background technique
Structure, the type of existing retarder are a lot, and it is planet wheel decelerator that a class retarder is wherein arranged, and the power input shaft of this retarder and pto are point-blank basically, and the cabinet great majority of existing retarder are ironcastings.Existing planet wheel decelerator is not suitable for the bigger gearing down of span between output shaft and the input shaft, and requires the less occasion of volume of cabinet again.Because the weight of cast iron cabinet is bigger, also be unfavorable for moving, transport and installing of retarder in addition, need to install additional coupling between dynamic again output shaft and the working machine, make its structure complicated, also increased the overall structure size of reducing gear simultaneously.Therefore, be necessary the structure of existing planet wheel decelerator is improved.
The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, designs that a kind of volume is little, in light weight, the big planet wheel decelerator of span between compact structure, power input shaft and the pto.
For achieving the above object, the technical solution of the utility model is the planet wheel decelerator of a kind of compact structure of design, it is characterized in that, described retarder comprises power input shaft and pto, between described power input shaft and pto, be provided with transmission shaft, the axis of described power input shaft, pto and transmission shaft is three parallel lines that are positioned at same plane, intermeshing driving gear is housed respectively on described power input shaft, pto and transmission shaft, and the driving gear that wherein is installed on the transmission shaft is the inertia driving gear; The casing of described retarder is provided with flanged connecting structure in the end that is positioned at pto one side.
For the link on the retarder is connected firmly, optimized technical scheme is, the casing of described retarder is an aluminium alloy box, and the position that described casing inherence is provided with the fastening piece connection is inlaid with steel bushing, and described steel bushing interconnects by the hole on keyway and key and the casing.
In order to make stable drive between the retarder internal gear, optimized technical scheme also has, and described driving gear is a helical gear.
Be convenient to be connected in order to make between retarder and the working machine, reduce connecting link, optimized technical scheme also has, described flanged connecting structure is on the casing of retarder, be provided with shoulder hole in the end that is positioned at pto one side, periphery at described shoulder hole is provided with bulge loop, is laid with several attachment holes on described bulge loop.
Optimized technical scheme also comprises, is provided with inner gear planetary frame wheel and planet wheel in the described shoulder hole in the end of described output shaft one side, and described planet wheel driving gear and described internal gear are meshed.
Advantage of the present utility model and beneficial effect are: because planet wheel decelerator of the present utility model is exclusively used in the transmission place that span is bigger between power input shaft and the pto.Therefore the technical solution of the utility model is to have increased an inertia drive wheel between power input shaft and pto, so both increased the wheelbase between power input shaft and the pto, its overall structure is not significantly strengthened, also can not reduce the transmission efficiency of retarder.Because the cabinet of this retarder has adopted aluminium alloy castings, its overall weight is reduced in addition, but because the hardness of aluminum alloy material is lower, if it is not enough that fastening screw trip bolt is fixed on the casing its join strength, the screw thread in the tapped hole is easy button easily.Therefore, the utility model has adopted the technical measures that install steel bushing at the position that is provided with the fastening piece screw additional, has so not only guaranteed join strength but also has reduced the overall weight of casing.Have again the utility model retarder for the ease of with working machine between quick firm being connected, the end of this retarder pto one side on cabinet directly is provided with flanged connecting structure, so just can save the parts of coupling and so on, its structure is simplified more, connect more convenient.
