Fig. 1 is a schematic diagram of the present utility model.

Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1, a stabilizer for a mixer includes a motor 10, an output shaft of the motor 10 is connected with a speed reducer 11, and the speed reducer 11 is connected with a main shaft 14 of the mixer by a key, so that the motor 10 can drive the main shaft 14 of the mixer to rotate.

The shell fixed connection of speed reducer 11 installs upper cover 13, installs upper cover 13 detachable (such as bolt) connection installation lower cover 20, installs lower cover 20 fixed connection fixing base 21, and fixing base 21 is located the below of installing lower cover 20, and fixing base 21 passes through bearing A24 and is connected with mixer main shaft 14.

The fixing seat 21 fixes the support frame 22, the support frame 22 is located below the fixing seat 21, is in a cone shape with big top and small bottom, and the lower end of the support frame 22 is connected with the main shaft 14 of the stirrer through a bearing B23.

In order to provide axial, radial dual constraint to the blender spindle 14, bearing a24 is a single thrust bearing and bearing B23 is a slide bearing. In this way, the bearing a24 can provide axial constraint to prevent the impact of the reaction force of raw water during stirring from making the main shaft 14 of the stirrer move up and down, meanwhile, the bearing B23 providing radial constraint is positioned lower, the main shaft operation fulcrum is positioned below the pool (also lower), the length of the transmission shaft of the underwater part is relatively shortened, and the rigidity of the main shaft is increased.

In order to prolong the service life of the bearing B23, one end of an oil pipeline 26 is communicated with the inside of an oil chamber of the bearing B23, the other end of the oil pipeline 26 is connected with an oil cup 25, and the oil cup 25 is arranged above the fixing seat 21. In this way, the bearings can be constantly filled with lubricating oil through the oil cup 25, increasing the service life of the apparatus. Meanwhile, the oil cup 25 is arranged above the fixed seat 21, so that lubricating oil can be conveniently filled (because equipment below the fixed seat 21 is possibly buried in raw water), and the oil cup 25 is arranged above the fixed seat, so that the filling is convenient.

In order to avoid damage to the speed reducer caused by entry of dust, rainwater and other slag, a protective cover 12 is arranged at the joint of the speed reducer 11 and the main shaft 14 of the stirrer.

The working principle is as follows:

during installation, attention needs to be paid:

s1, fixing base 21 and the civil engineering mounting platform are fixed on the pre-buried connecting steel plate of the mounting platform by using the connecting steel plate, and the flatness of fixing base 21 is corrected in the mounting process, so that the perpendicularity of main shaft 14 of the mixer is ensured.

S2, the speed reducer is fixed on the fixed seat 21 through the upper cover 13 and the lower cover 20, and is firmly fixed through bolts.

The working process comprises the following steps:

in use, the rotation of the blender main shaft 14 is not affected by the support of the two bearings (bearing A24 and bearing B23).

The stirrer drives the stirrer main shaft 14 to rotate through the speed reducer, and the stirrer main shaft 14 is supported by a one-way thrust bearing, so that the stirrer main shaft has enough strength and rigidity and good stability.

The main shaft 14 of the stirrer is connected with the stirring shaft in a flange connection mode, and the blades are fixed on the stirring shaft by bolts and rotate along with the rotation of the driving shaft, so that the aim of mixing and stirring is achieved. The bearings are lubricated by the lubricating grease in the oil chamber, so that long-term safe and reliable operation of the equipment can be ensured.

The characteristics of this patent:

s1, the upper end of a main shaft penetrates through a speed reducer and is connected with the speed reducer by a key, and a shield is arranged on the upper end of the main shaft to prevent dust, rainwater and other slag from entering and damaging the speed reducer;

s2, a sliding bearing structure is arranged at the lower end of the fixed seat, so that a main shaft operation fulcrum is arranged below the pool, and the rigidity of the main shaft is increased;

s3, a one-way thrust bearing is arranged in the middle of the fixing seat, so that the main shaft is ensured to be only subjected to axial force in the operation process, and the whole structure is stable and reliable in operation;

and S4, an oil cup is arranged at the one-way thrust bearing, so that lubricating oil is often filled into the bearing, and the service life of the device is prolonged.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
