Heating device for large bearing of mining machinery

Abstract

The invention discloses a heating device for a large bearing of mining machinery. The heating device comprises a machine frame and further comprises a first box body, an electric cylinder, a second box body, an oil spraying pipe, an oil supply system and an oil return system; an opening is formed in the left side of the first box body, a driving device is installed on the outer wall of the right side of the first box body, a bearing placement assembly is arranged in the first box body, and the bearing placement assembly is connected with the output end of the driving device through a rotatingshaft; the electric cylinder is arranged on the machine frame and is horizontally arranged, the middle of the outer wall of the left side of the second box body is fixedly connected with the top end of an output rod of the electric cylinder, an opening is formed in the right side of the second box body, the right end of the oil spraying pipe is located in the second box body, the left end of the oil spraying pipe is located on the left side of the left side wall of the second box body, the oil supply system is connected with the left end of the oil spraying pipe, and the oil return system is used for recycling oil sprayed to the bearing by the oil spraying pipe and conveying the oil back to the oil supply system. The heating device can conveniently and effectively wash and heat the large bearing.

Description

technical field [0001] The invention relates to the field of bearing heating devices, in particular to a heating device for large-scale bearings of mining machinery. Background technique [0002] There are many ways to heat bearings, such as heating in a heating box, heating on a heating plate, heating in an oil bath, and heating by an induction bearing heater, among which oil bath heating and induction bearing heater are the most commonly used. Compared with oil bath heating, induction bearing heater heating has the advantages of fast heating speed, safe and reliable heating process, no open flame, no pollution, etc., and is more favored by enterprises. For large bearings used in mining machinery, large induction bearing heaters can be used for heating, but the installation of most large bearings is more difficult, and sometimes it takes multiple installations to install successfully. Reinstallation can only be carried out after reheating. The installation of large-scale ...

Problems solved by technology

[0003] The object of the present invention is to provide a heating device for large-scale bearings of mining machinery, which aims to use the induction-type bearing heater to heat large-scale bearings for mining machinery because the induction-type bearing heater does not have the function of cleaning and removing impurities entering the bearing. When heating, it is also necessary to equip a bearing cleaning device, and it is necessary to switch between the two, which makes it very troublesome to use
