Abstract
The utility model relates to an improvement of an actuating speed-transformation device of a watermill automatic aerator, wherein a cylindrical pinion is arranged on the spindle nose of an electromotor, and a cylindrical gear is driven by the cylindrical pinion. A bevel pinion is installed on the same shaft of the cylindrical gear which is driven by the bevel pinion, and a shaft is connected and driven by a bevel gear via a shaft coupling. The utility model employs a cylindrical gear pair at high gear and a bevel gear pair at low gear, thereby the dynamic efficiency is higher and the noise is low. The utility model is not easy to abrade and is durable, and the structure is reasonable.
Description
The utility model relates to a kind of aerator, particularly a kind of transmission device of horizontal aerator.
The drive transmission device majority of existing waterwheel aerator has adopted the worm speed-down transmission, its dynamic efficiency is generally on the low side, easy to wear, working life is shorter, influences the main performance of product, also has a kind of drive transmission device of waterwheel aerator to adopt secondary to connect transmission gear shift, improved dynamic efficiency, but noise is bigger, and is easy to wear, and serviceability is relatively poor.
The purpose of this utility model provides a kind of dynamic efficiency height, and it is single low, not easy to wear to make an uproar, and serviceability is the waterwheel aerator drive transmission device of secondary gear transmission gear shift preferably.
For realizing this purpose, the utility model provides following technological scheme:
Comprise motor and transmission shaft, wherein the motor spindle nose is equipped with the cylinder small gear, and the cylinder small gear drives the cylinder gearwheel, on the same axle of cylinder gearwheel bevel pinion is installed, bevel pinion drives large bevel gear, and large bevel gear axially connects transmission shaft through coupling.
The utility model is owing to adopt cylindrical gear pair at top gear, and bottom gear adopts the secondary gear transmission of umbrella gear pair, so dynamic efficiency is higher, and noise is lower, and not easy to wear, structure is more reasonable, and serviceability is better.
Now in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a transmission schematic representation of the present utility model;
As shown in Figure 1 and Figure 2, the utility model comprises motor 1, transmission shaft 2; Wherein motor spindle nose 3 is equipped with cylinder small gear 4, and cylinder small gear 4 drives cylinder gearwheel 5, on the same axle 6 of cylinder gearwheel 5 bevel pinion 7 is installed, and bevel pinion 7 drives large bevel gear 8, and large bevel gear 8 axially connects transmission shaft 2 through coupling 9.
Cylinder small gear 4 and cylinder gearwheel 5 can be helical teeth shapes.
