Abstract
The utility model discloses an unfolding-type secondary gear reducer. The unfolding-type secondary gear reducer comprises high-speed shafts, an intermediate shaft and a low-speed shaft, wherein the high-speed shafts are meshed with each other. The high-speed shafts are in key joint with a first gear. The low-speed shaft is in key joint with a fourth gear. The intermediate shaft is provided with a second gear and a third gear through key connections, wherein the second gear and the third gear are meshed with the first gear and the fourth gear. The high-speed shafts and the low-speed shaft are respectively provided with a bob-weight plate. The unfolding-type secondary gear reducer is simple and practical, suitable for various motors, capable of carrying out variable transmission stably and effectively and reducing shaft deformation caused by uneven load.
Description
Technical field
The utility model relates to a kind of retarder, relates in particular to a kind of expansion secondary gear reducer.
Background technique
The expansion secondary gear reducer is modal a kind of in retarder.This retarder is larger at the load of running high speed axle and lower velocity shaft, especially high speed shaft, due to gear, bearing skewness, although strengthen axle intensity on technique, but in installation, using process, after especially long-time practicality, the distortion of axle can occur still, cause load skewness on the facewidth, affect retarder efficient.
The model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of minimizing to cause a kind of expansion secondary gear reducer of shaft distortion because of the load inequality.
Technological scheme: for achieving the above object, a kind of expansion secondary gear reducer of the present utility model, comprise intermeshing high speed shaft, jack shaft and lower velocity shaft, described high speed axle key connects the first gear, described low speed axle key connects the 4th gear, and described jack shaft is connected with by key the second gear and the 3rd gear that meshes with the first gear and the 4th gear respectively;
Described high speed shaft and lower velocity shaft respectively are provided with a balancing disk.
As preferred version of the present utility model, the described first gear number of teeth is 20, and the described second gear number of teeth is 145, and described the 3rd gear number of teeth is 28, and described the 4th gear number of teeth is 122; This scheme velocity ratio is realized the stable operation of drive system, adds two balancing disks, can alleviate the shaft distortion that causes because load is irregular.
Beneficial effect: a kind of expansion secondary gear reducer of the present utility model is simple and practical, is applicable to multiple motor, can stablize, effectively carry out gear, can reduce the shaft distortion that causes because load is irregular.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, expansion secondary gear reducer of the present utility model, comprise intermeshing high speed shaft 1, jack shaft 2 and lower velocity shaft 3, high speed shaft 1 key connects the first gear 4, lower velocity shaft 3 keys connect the 4th gear 5, and jack shaft 2 is connected with by key the second gear 6 and the 3rd gear 7 that meshes with the first gear 4 and the 4th gear 5 respectively; High speed shaft 1 and lower velocity shaft 3 respectively are provided with a balancing disk 8.Balancing disk is connected with its axle to use by flat key connection or spline joint.The first gear number of teeth of this fact Example is that 20, the second gear numbers of teeth are that 145, the three gear numbers of teeth are that 28, the four gear numbers of teeth are 122.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
