Problems solved by technology
Due to the high-speed rotation of the rotating shaft 5, processing errors and vibrations cause the coaxial error of the left bearing seat 21 and the right bearing seat 22, which intensifies the friction between the bearing seat and the bearing, resulting in the left bearing 71, the right bearing 72 and other bearings. The temperature of the seal on the machine will gradually increase, which will damage the bearing and seal, and affect the working efficiency of the entire machine.

The invention discloses a bearing pedestal used for a crusher. The bearing pedestal comprises a base provided with a bearing installation groove. The base comprises cooling paths, a cooling liquid inlet and a cooling liquid outlet, wherein the cooling paths are disposed in the base and used for guiding cooling liquid, and the cooling liquid inlet and the cooling liquid outlet are communicated with the cooling paths. In a normal working state of the crusher, the cooling liquid flows in through the cooling liquid inlet from the outside, flows along the cooling paths, and flows out from the cooling liquid outlet to return to the outside. In a flowing process of the cooling liquid, the cooling liquid absorbs a large amount of heat generated by the bearing pedestal and a bearing, and dissipates heat of the bearing pedestal, thus lowering the temperature of the bearing and a seal of the bearing.
Description
technical field [0001] The invention relates to the field of mining engineering machinery, in particular to a bearing seat on a crusher. In addition, the present invention also relates to a crusher comprising the above-mentioned bearing seat. Background technique [0002] With the development of China's mineral mining industry, various types of mining construction machinery have been widely used. Now, they are developing in the direction of high speed and high efficiency. [0003] At present, in the technical link of ore processing, taking the crusher as an example, it is required to be able to quickly crush the ore, which must be completed by rotating parts such as shafts that can rotate at high speeds. At the same time, in order to ensure the reliability and durability of the machinery and reduce the mining cost, it is required that the bearings and housings matched with the high-speed rotating shaft have high quality and reliability. [0004] Please refer to figure 1 ...
