A heating device for large bearings of mining machinery

Abstract

The invention discloses a heating device for large bearings of mining machinery, which includes a frame, a first box, an electric cylinder, a second box, an oil injection pipe, an oil supply system and an oil return system, and The left opening is set, and the drive device is installed on the right outer wall of the first box body. The bearing placement assembly is installed in the first box body, and the bearing placement assembly is connected to the output end of the drive device through a rotating shaft; the electric cylinder is set on the frame. , and the electric cylinder is set horizontally; the middle position of the outer wall on the left side of the second box is fixedly connected with the top end of the output rod of the electric cylinder, the opening on the right side of the second box is set, the right end of the fuel injection pipe is located in the second box, and the left end Located on the left side of the left wall of the second box body, the oil supply system is connected to the left end of the oil injection pipe, and the oil return system is used to recover the oil sprayed by the oil injection pipe to the bearing and send it back to the oil supply system; the present invention Allows for easy and efficient flushing and heating of large bearings.

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
