Lubricating device of wheel shifting shaft of sterile filling machine

Abstract

The invention discloses a lubricating device of a wheel shifting shaft of a sterile filling machine. A shifting wheel is rotationally arranged inside a bearing sleeve through an upper end bearing and a lower end bearing; the bearing sleeve penetrates through and is fixed on a frame; the upper end and the lower end of the wheel shifting shaft are respectively matched with the bearing sleeve through an upper sealing ring and a lower sealing ring; a clearance between the wheel shifting shaft and the bearing sleeve is sealed to form a lubricating cavity by the upper sealing and the lower sealing ring; the upper end bearing and the lower end bearing are arranged inside the lubricating cavity; a lower lubricating opening communicated with a lower lubricating oil way, and an upper lubricating opening communicated with an upper lubricating oil way are formed in the lower end of the bearing sleeve; the lower lubricating opening is communicated with the lubricating cavity between the lower end bearing and the lower sealing ring; the upper lubricating opening is communicated with the lubricating cavity between the upper end bearing and the upper sealing ring through an axial slideway arranged on the sleeve wall of the bearing sleeve; a vent hole communicated with the lubricating cavity is formed in the bearing sleeve. The lubricating device is simple in structure, and free of a dusty corner, and a table board of the frame is concise and clean on the premise of ensuring full lubrication of the upper end bearing.

Description

technical field [0001] The invention relates to a lubricating device, in particular to a lubricating device for a dial shaft of an aseptic filling machine. Background technique [0002] The two ends of the dial shaft of the aseptic filling machine are installed in a bearing sleeve through bearing rotation, and the bearing sleeve is fixed on the frame and runs through the frame; above the frame is a sterile space. The upper and lower end bearings of the dial shaft need to be lubricated. The lower bearing is lubricated in the external environment, so it is very easy to lubricate, while the upper bearing is lubricated by fixing an oil pipe directly above the frame. The oil pipe is directly connected to the top of the bearing sleeve, so that there is a sanitary dead corner that is difficult to clean on the table, which cannot meet the requirements. Some aseptic filling fields. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
