Abstract
The utility model provides an improved reducing mechanism of an impeller type fish pond oxygen-increasing machine. The utility model is characterized in that the improved reducing mechanism of the impeller type fish pond oxygen-increasing machine is composed of a box body, a bearing sleeve and the bearing seats of the two ends of a gear shaft of the prior art in an integral casting mode, and a box cover is cancelled and directly replaced by the end cover of an electric machine. The utility model which is suited to be used by the impeller type fish pond oxygen-increasing machine has the advantages of simple structure, light weight, low cost and high quality.
Description
The utility model relates to a kind of improved paddle aerator reducing gear.
In prior art, the vane type oxygen-enriching machine in fish pond mainly is made up of motor, reducing gear, impeller, support and floating drum.Its reducing gear structural similarity as shown in Figure 1.Fig. 1 is the cutaway view of the vane type oxygen-enriching machine in fish pond reducing gear of Guangdong Province's Shunde County second farm build factory.This reducing gear is a kind of coaxial-type two-stage cylinder gear speed reducer, and it mainly is made up of case lid (3), casing (4), gear (5,6,7,8), gear shaft (9), bearing holder (housing, cover) (10) and output shaft (11).Motor (1) is installed on the case lid (3) by its end cap (2).Driving gear (5) is contained on the main shaft of motor (1).The bearing block of gear shaft (9) is formed by the body of case lid (3) and casing (4).The weak point of this reducing gear is that end seat (2), case lid (3), casing (4) and the bearing holder (housing, cover) (10) of motor will have higher quality of fit, could guarantee that electric machine main shaft and output shaft (11) are on same axis.Therefore, not only increased processing cost, and be difficult for again ensuring the quality of products.
The purpose of this utility model is the deficiency that will overcome prior art, provides a kind of simple in structure, guarantees the vane type oxygen-enriching machine in fish pond reducing gear of electric machine main shaft and output shaft (11) axiality easily.
The purpose of this utility model can realize by following measure: as shown in Figure 2 that the bearing block casting at casing (4), bearing holder (housing, cover) (10) and gear shaft (9) two ends of prior art is in aggregates, i.e. and casing (12); Cancel case lid (3), make the case lid (3) of casing (4) with the end cap (2) of motor (1).
Fig. 2 is the cutaway view of the utility model concrete structure.
Among the figure, (1) is motor, and (2) are end cap, and (12) are casing, and (5,6,7,8) are gear, and (9) are gear shaft, and (11) are output shaft, and (13) are sealing ring.
For the ease of assembling and raising installation accuracy, end cap (2) can not adopt the end cap face of original motor and process in addition.In addition,, avoid, can on end cap (2), process a supporting, make between end cap (2) and the gear (5) and can load onto a sealing ring motor on the lubricating oil band in order to prevent end cap (2) leakage of oil.
Because the utility model has been cancelled case lid of the prior art (3) and bearing holder (housing, cover) (10), not only alleviated the weight of reducing gear, save material and save machining period, and because the minimizing of fitting surface, accumulated error when correspondingly having reduced assembling, guarantee easily the main shaft of motor (1) and the axiality of output shaft (11), improve the quality of products. Therefore, the utility model compared with prior art has advantage simple in structure, in light weight, that cost is low, noise is few and quality is high.
Claims (2)
1, a kind of vane type oxygen-enriching machine in fish pond reducing gear, it mainly is made up of end cap (2), casing (12), gear (5,6,7,8), gear shaft (9) and output shaft (11).It is characterized in that casing (12) is that bearing block monoblock cast by casing of the prior art (4) bearing holder (housing, cover) (10) and gear shaft (9) two ends forms; Cancel case lid of the prior art (3), directly make the end cap of casing (4) with the end cap (2) of motor.
2, reducing gear according to claim 1 is characterized in that between end cap (2) and gear (5) sealing ring (12) being housed also.
