The bearing on the mixer is similar to the spherical roller bearing. The main manufacturer is FAG Bearing Company. The bearing used on the mixer shaft is mainly subjected to radial force and secondly to axial force. The bearing is selected to have the bearing with axial force. Such as angular contact ball bearings, tapered roller bearings, or external thrust ball bearings, angular contact ball bearings for high speed, tapered roller bearings or external thrust ball bearings for dynamic bearings.

Construction mixer is a necessary mechanical equipment for construction projects. There are many components and components. Among them, bearings and motors are more important. Today we will talk about bearings in detail.

1. The role of the bearing

The role of the bearing is to support the role. If the mixing shaft of the building mixer is directly matched with the hole, one transmission resistance is large. Secondly, after the wear is large, the transmission member is not easy to replace, and the bearing relies on the rolling contact between the components. To support the transmission parts, it has the characteristics of small sliding resistance, low power consumption, and easy starting.

2. Selection of bearings

The bearing is a relatively delicate component. The service life determines the service life of the spindle, which affects the service life of the building mixer. In many cases, the bearing has a national standard. Usually, the unit of the machining axis will be in accordance with the demand. The shaft strength is produced in accordance with the national standard. In the selection of bearings, it is necessary to select bearings with stable operation and low noise, that is, a series of practical summaries and theoretical calculations.

Bearing installation and use

1. The shaft bears the full load of the negative machine, so good lubrication has a great relationship with the bearing life. It directly affects the service life and operation rate of the machine. Therefore, the required oil must be cleaned and the seal must be good. Main oil filling (1) Rotary bearing (2) Roller bearing (3) All gears (4) Active bearing, sliding plane.

2. The newly installed tires are prone to loosening and must be inspected frequently.

3. Pay attention to whether the work of all parts of the machine is normal.

4, pay attention to check the wear level of wearable parts, always pay attention to replace the worn parts.

5. The plane of the undercarriage of the movable device should be out of dust and other materials to prevent the movable bearing from moving on the chassis when the machine encounters unbreakable materials, resulting in serious accidents.

6, the bearing oil temperature rises, should be stopped immediately to check the reasons to eliminate.

7. If there is impact sound when the rotating gear is running, it should be stopped immediately to check and eliminate
