Description

Improve mixer of motor axis of rotation and stirring shaft concentricity

Technical Field

The utility model belongs to the technical field of agitated vessel, especially, relate to an improve mixer of motor axis of rotation and stirring shaft concentricity.

Background

Currently, the closest prior art in the industry:

the power of a rotating shaft of a motor of the existing stirrer is synchronized to a stirring shaft by adopting a synchronous wheel belt connection mode, and the structure of the stirring shaft is composed of an upper bearing plate, a rotating shaft, a synchronous wheel, a synchronous belt, a bearing, a supporting rod, a stirring shaft and a lower bearing plate. The upper and lower bearing plates are fixed by screws. In the installation process, the bearing centers of the upper bearing plate and the small bearing plate are difficult to be ensured to be in the same center, namely the concentricity is not good. Poor concentricity can cause the defects of serious shaking of the stirring shaft, noise, large mechanical friction heating of a machine and the like. Meanwhile, the upper bearing plate and the lower bearing plate are fixed by screws, and the stirring machine works for a long time, so that the structure is easy to loosen. Affecting the service life of the instrument.

In summary, the problems of the prior art are as follows:

(1) when a rotating shaft of a stirrer motor and a stirring shaft are connected and mounted, the bearing centers of an upper bearing plate and a small bearing plate are difficult to be ensured to be in the same center, so that the defects of severe shaking of the stirring shaft, sound noise, large mechanical friction heating of a machine and the like are caused;

(2) the upper bearing plate and the lower bearing plate are fixed by screws, and the stirrer works for a long time, so that the structure is easy to loosen, and the service life of an instrument is influenced.

The difficulty of solving the technical problems is as follows:

at present, an upper bearing plate and a lower bearing plate of a stirrer are machined secondarily, and an error exists in the machining process. The upper bearing plate and the lower bearing plate of the stirring machine are fixed by screws, and in the installation process, the upper bearing plate and the lower bearing plate are assembled to have errors, so that the same concentricity is hardly ensured. The upper bearing plate and the lower bearing plate of the stirring machine are fixed by screws, and the screws can loosen after long-time operation.

The significance of solving the technical problems is as follows:

the bearing plate is the upper bearing plate and is set up with lower bearing plate integration, because is the integration preparation, assembles the convenience. The concentricity is good. The stirring shaft does not shake due to poor concentricity. The noise is very little, and machine mechanical friction generates heat for a short time. The bearing plate is for going up the bearing plate and set up with lower bearing plate integration, simple to operate sparingly installs the labour. Meanwhile, the device is integrated, the quality is more stable, and the device cannot be loosened due to long-time work and influence the service life of the device.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides an improve mixer of motor axis of rotation and stirring shaft concentricity.

The utility model discloses a realize like this, a mixer that improves motor axis of rotation and stirring shaft concentricity is provided with:

a bearing plate;

the bearing plate is integrated setting for upper bearing plate and lower bearing plate, the fixed slot has been seted up to the bearing plate left end, both ends are equipped with upper bearing and lower bearing respectively about the fixed slot is inside, the (mixing) shaft runs through in upper bearing and lower bearing, the cover is equipped with driven synchronizing wheel in the middle of the (mixing) shaft, driven synchronizing wheel passes through the hold-in range and is connected with transmission.

Further, transmission is provided with the motor, the motor passes through the bolt fastening at bearing plate right-hand member upside, the output shaft outside cover of motor is equipped with the initiative synchronizing wheel, and the initiative synchronizing wheel passes through the hold-in range and is connected with the driven synchronizing wheel.

To sum up, the utility model discloses an advantage and positive effect do:

the utility model discloses set up upper and lower bearing plate into overall structure, the monoblock material processing is adopted to upper and lower bearing plate, bracing piece, does not need the screw fixation during installation. The bearing center that can guarantee to go up the bolster and the lower bearing plate is on same center, and the concentricity is good, and upper and lower bearing plate need not the screw fixation, and the long-time work of mixer can not cause the structure not hard up, has prolonged the life of instrument.
