Whether the jaw crusher can operate normally during crushing is directly related to the bearing, so the bearing quality is closely related to the performance of the machine. Therefore, how to choose the bearing of jaw crusher is a topic that every consumer must discuss. This paper summarizes the following several key selection directions.
1. Whether the bearing cleaning is simple.
Bearing cleaning is a common work, which is carried out once every two months. Generally, the bearing cleaning can be carried out by gasoline scrubbing, but the bearing needs to be purchased and cleaned by special cleaning props, which is not only troublesome but also a waste of production cost.
2. Whether the installation and removal are convenient. Because the jaw crusher works in high temperature and high speed for a long time, the consumption is very large. The bearing belongs to vulnerable parts, and the probability of damage is relatively large. It is frequently replaced. If it is inconvenient to dismantle or install, it will greatly affect the construction progress. It is recommended to choose a bearing with simple and convenient installation.
3. Type of bearing. Due to the working property of jaw crusher, the impact load of bearing in production is large; it is suggested that spherical roller bearing can be selected when purchasing. This kind of bearing can bear radial load and axial load in two directions, especially suitable for the work of heavy machinery such as jaw crusher.
4. Whether it is economically applicable. When selecting the jaw crusher bearing, first of all, its economic applicability should be taken into account. When it can protect the machine or work, the damage rate is small, and the variety of bearing should be minimized, so as to reduce the cost of production and use as much as possible.
5. Accuracy of bearings. The bearing accuracy of jaw crusher mainly includes two aspects: dimension tolerance and rotation accuracy. Because the machine generally moves at the main shaft speed lower than 300r / min, its general accuracy is easy to produce identification error. It is suggested that the bearing with higher accuracy should be selected when selecting the bearing.
