Embodiment 1

[0025] according to Figure 1 to Figure 3 As shown, a granulator pressure wheel bearing lubrication system includes a feed housing 1, a main shaft 2, a pressure wheel shaft 3 rotating with the main shaft 2, a pressure wheel 4 rotating on the pressure wheel shaft 3, and a high oil tank 5. The high-level oil tank 5 is provided with a fixed bushing 6 and an oil pump 7, the fixed bushing 6 is connected to the output shaft of the oil pump 7, the fixed bushing 6 is fixed on the feed shell 1, and the high-level oil tank 5 and the oil pump 7 shell rotate synchronously. The pinch shaft 3 is provided with a first oil passage 11, the high oil tank 5 communicates with the first oil passage 11 of the pinch shaft 3, the high oil tank 5 and the pinch shaft 3 rotate synchronously, the main shaft 2 is provided with a second oil gallery 12, and the second oil The two ends of the channel 12 communicate with the first oil channel 11 , the middle position of the second oil channel 12 communicates ...

Embodiment 2

[0036] according to Figure 4 to Figure 5 As shown, the fixed shaft sleeve 6 is provided with a fourth oil passage 24, and the output shaft of the oil pump 7 is provided with a fifth oil passage 25. The oil pump 7 communicates with the fourth oil passage 24 through the fifth oil passage 25, and the oil pump 7 connects with the fourth oil passage 24. The oil suction port sucks oil, and the oil is pumped out through the fifth oil passage. The upper end of the fourth oil passage 24 communicates with the cooler 10 through the first cooling pipe 23 , and the cooler 10 communicates with the high oil tank 5 through the second cooling pipe 26 .

[0037] In this embodiment, the lubricating oil sucked into the oil pump 7 enters the cooler 10 through the fourth oil passage 24, the fifth oil passage 25 and the first cooling pipe 23, and the lubricating oil cooled by the cooler 10 passes through the second The cooling pipe 26 returns to the high oil tank 5, and the oil temperature is well ...

Abstract

The invention discloses a granulator press wheel bearing lubricating system, which comprises a feeding casing, a main shaft, a press wheel shaft, a press wheel and a high-position oil tank, wherein the press wheel shaft rotates along with the main shaft; the press wheel rotates on the press wheel shaft; a fixed shaft sleeve and an oil pump are arranged in the high-position oil tank; the fixed shaft sleeve is connected with an output shaft of the oil pump and is fixed onto the feeding casing; the high-position oil tank and an oil pump case synchronously rotate; a first oil passage is arranged in the press wheel shaft; the high-position oil tank communicates with a first oil passage of the press wheel shaft; the high-position oil tank and the press wheel shaft synchronously rotate; a secondoil passage is arranged in the main shaft; the two ends of the second oil passage communicate with the first oil passage; the middle position of the second oil passage is communicated with an oil suction opening of the oil pump; the oil pump is communicated with the high-position oil tank. A rotating joint is not needed; lubricating oil circulates in a negative pressure oil suction mode; the pressure is small; the damage to a sealing element is small; the service life of the sealing element is prolonged.

Description

technical field [0001] The invention relates to the technical field of oil lubrication, in particular to a lubricating system for a pressure wheel bearing of a granulator. Background technique [0002] At present, there are two self-rotating pressure rollers on the main shaft of the granulator. When the main shaft rotates, the pressure rollers rotate by friction with the mold. Because the pressure rollers are under high pressure, the grease is easy to deteriorate. It has always been passed by an external dry oil pump. The rotary joint installed on the frame plate is used to supply oil to the two pressure rollers. The rotary joint in the lubricating circuit is easily damaged and the grease is wasted; and due to the high pressure of the dry oil pump, the lip seal ring of the pressure roller will be broken, resulting in pressure loss. The internal lubrication of the wheel is polluted by dust, which shortens the life of the pressure wheel bearing. Contents of the invention ...
