Description

Aerator's transmission

technical field

The utility model relates to an aerator used in the aquaculture industry, in particular to a transmission device of the aerator.

Background technique

There are two commonly used aeration methods for existing aerators. The first is the waterwheel type aeration, and the second is the impeller type aeration. The waterwheel type has a large oxygenation area, and the impeller type can increase the water depth. oxygen. But there is not yet a kind of aerator that can realize waterwheel type aeration and impeller type aeration simultaneously. And the transmission device supporting with the aerator also can't finish these two different functions at present.

Contents of the invention

Therefore, the purpose of this utility model is to provide a kind of transmission device that is used for the aerator, so that the aerator can realize waterwheel type aeration and impeller type aeration simultaneously.

The purpose of this utility model is achieved in that:

A transmission device for an aerator, including a motor and a gear box. The motor is installed on the gear box. Gear meshing, the first driven bevel gear is installed on a rotating shaft, and the driving cylindrical gear is also arranged on the rotating shaft, and the rotating shaft is arranged in the gearbox, the first driven bevel gear, the driving cylindrical gear and the rotating shaft rotate synchronously, and the driving cylindrical gear and The driven cylindrical gear meshes, and the driven cylindrical gear is installed on the first output shaft, thereby driving the first output shaft to rotate. The first output shaft is installed horizontally on the gearbox, and the second driving bevel gear is also arranged on the first output shaft. The second driving bevel gear rotates with the first output shaft;

The second driving bevel gear meshes with the second driven bevel gear, and the second driven bevel gear is installed on the top of the second output shaft to drive the second output shaft to rotate. The second output shaft is vertically installed on the gearbox, and the second output The shaft is perpendicular to the first output shaft.

If a water wheel is installed at both ends of the first output shaft, and an impeller is installed at the end of the second output shaft, the water wheel and the impeller are driven by the motor to rotate at different speeds in different directions at the same time, so that one machine can have water at the same time. The purpose of the car-type aerator and the impeller-type aerator.

In the above technical solution, the tooth shape of the bevel gear can be straight teeth, helical teeth, arc teeth; the tooth shape of the cylindrical gear can be straight teeth, helical teeth, or herringbone teeth.

The diameter of the first driven bevel gear is larger than the diameter of the first driving bevel gear to achieve the first deceleration.

The diameter of the second driven cylindrical gear is larger than the diameter of the second driving cylindrical gear to realize the second deceleration.

The utility model has reasonable structural design, compact structure, convenient assembly and disassembly, high transmission efficiency, and one reducer realizes two-axis output in different directions and at different speeds. When the water wheel is installed at both ends of the first output shaft and the impeller is installed at the end of the second output shaft, the waterwheel type oxygenation and the impeller type oxygenation can be completed by one aerator at the same time, thus improving the oxygenation rate. Efficiency, cost savings, and energy savings.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Embodiment, with reference to Fig. 1 to Fig. 5, a transmission device of an aerator includes a motor 1 and a gear box 2, the shaft head 100 of the motor 1 is equipped with a first driving bevel gear 5, the first driving bevel gear 5 It meshes with the first driven bevel gear 6, thereby driving the gear shaft 7 connected with the first driven bevel gear 6 to rotate. The gear shaft 7 is perpendicular to the shaft head of the motor 1 and fixed by rolling bearings, and is horizontally arranged in the gearbox. The gear shaft 7 is integrated with the small cylindrical gear 70, and the small cylindrical gear 70 meshes with the large cylindrical gear 8, thereby driving the first output shaft 3 connected with the large cylindrical gear 8 to rotate. The first driving bevel gear 5 and the first driven bevel gear 6 form the first stage of deceleration, and the small cylindrical gear 70 on the gear shaft 7 and the large cylindrical gear 8 realize the second stage of deceleration. The first output shaft 3 outputs power through two-stage deceleration. The first output shaft 3 is arranged horizontally, and its two ends extend outside the two sides of the gearbox 8 .

The second driving bevel gear 9 is installed on the first output shaft 3 and is linked with the first output shaft 3. The second driving bevel gear 9 meshes with the second driven bevel gear 10, thereby driving the second driven bevel gear 10 The connected second output shaft 4 rotates, and then transmits the power to the second output shaft 4 for output. The second output shaft is vertically arranged to be perpendicular to the first output shaft, and its bottom protrudes from the bottom of the gearbox 2 to realize the output direction change. The gear box has two output shafts with different rotation speeds in different orientations like this.

When the water wheel is mounted on both ends of the first output shaft 3 and the impeller is mounted on the end of the second output shaft 4, the water wheel type oxygenation and the impeller type oxygenation can be carried out simultaneously on one aerator, which improves the oxygenation rate. Efficiency saves energy and saves costs.
