AI Technical Summary

Technical Problem

The existing crusher bearing housings lack effective heat dissipation and sludge removal mechanisms, resulting in bearing overheating, decreased lubrication performance, shortened service life, and difficulty in cleaning sludge, which affects equipment stability and production efficiency.

Method used

A combined bearing housing was designed, which includes a heat exchange and cooling mechanism and a support cleaning mechanism. It achieves efficient heat dissipation through components such as heat exchange fins, jet nozzles and fans, and automatically scrapes and collects sludge through scrapers and magnetic structures to avoid sludge accumulation.

Benefits of technology

It effectively prevents bearing overheating, ensures bearing performance and service life, improves equipment reliability and production efficiency, and simplifies sludge cleaning operations.

Abstract

The invention relates to the technical field of bearing seats, in particular to a combined bearing seat of a crusher, which comprises a lower support, an upper support is mounted on the lower support, a bearing is jointly mounted on the lower support and the upper support, a heat exchange cooling mechanism is arranged on the upper support, and a bearing is mounted on the heat exchange cooling mechanism. The heat exchange cooling mechanism comprises a heat exchange outer layer fixedly connected to the upper support, automatic scraping and collecting of oil sludge can be achieved through cooperation of structures such as an electric rod, a rotary disc and a scraping plate, the oil sludge cleaning operation can be completed without detaching the support, the scraped oil sludge is collected through a side box and guided through a turning plate, and finally the oil sludge flows into a sludge storage box to be treated in a centralized mode. Oil sludge is prevented from being accumulated on the inner wall, cleanliness of the inner wall of the support is effectively guaranteed, it is guaranteed that the heat dissipation efficiency of the heat exchange fins and the support is not affected by the oil sludge, meanwhile, the oil sludge is prevented from permeating into a bearing fit clearance, bearing rotation flexibility is guaranteed, transmission resistance is reduced, and the working reliability and the service life of the crusher are further improved.
