Problems solved by technology

Its shortcomings: First, the working environment of the metal wet belt grinder has both water and tiny grinding metal particles. The tiny metal particles and sewage are in the working process of the metal wet belt grinder. , the spindle bearing of the abrasive belt grinder cannot intrude the fine metal particles and cutting fluid into the bearing seat during the high-speed rotation process. If the fine metal particles cannot be effectively prevented from entering the bearing seat, the bearing will inevitably be damaged. The high-speed bearing in the seat is mixed with fine metal particles, causing the bearing to heat up and burn out

Embodiment 1

[0016] Embodiment 1: with reference to attached figure 1 . The main shaft bearing sealing and lubricating structure of the wet abrasive belt grinder includes a main shaft 2 and a bearing seat 1. The processing of the main shaft and the bearing seat (aligning or non-aligning) is a prior art, and will not be described here. The cavity formed by the bearing 3 and the sealing ring 6 in the bearing seat 1 or between the two bearings 3 is an oil chamber 4 and an oil inlet channel 5 is opened on the wall of the oil chamber, that is to say, the cavity where the bearing is installed in the bearing seat Bearing 3 and sealing ring 6 are installed at both ends respectively, and the cavity (cavity) formed between bearing 3 and sealing ring 6 is the oil cavity 4 mentioned in the present invention, or the two ends of the cavity where the bearing seat is installed with bearing are installed respectively. Bearing 3 is arranged (bearing 3 replaces sealing ring 6 and bearing 3 is a single-sided...

Embodiment 2

[0017] Embodiment 2: On the basis of Embodiment 1, the method of sealing and lubricating the main shaft bearing of the wet abrasive belt grinder, the oil (lubricating oil) located in the oil chamber in the bearing seat is in the process of the main shaft driving the bearing to rotate at a high speed, and the oil located in the bearing The oil is heated by the heat generated by the high-speed rotation of the bearing to generate a small amount of oil vapor, which forms a positive pressure in the oil chamber and forces the grease in the oil chamber to supply oil to the bearing and to the sealing ring in contact with the spindle. The oil pressure is applied positively to the inner surface or the bearing sealing ring surface to prevent external impurities from invading the bearing and sealing ring, and the oil is continuously replenished into the oil chamber through the oil inlet passage.

Embodiment 3

[0018] Embodiment 3: with reference to attached figure 2 . Wet abrasive belt grinding motorized roller bearing seal lubrication structure, it comprises main shaft 2 and moving roller 7, the processing and making of main shaft 2 and moving roller 7 are prior art, do not narrate here. The central recess at the end of the moving roller is the bearing seat, the cavity formed by the bearing 3 and the sealing ring 6 or the two bearings 3 in the bearing seat is the oil chamber 4, and the main shaft 2 has an oil inlet channel 9 in the axial direction and is connected with The oil chamber 4 in the bearing seat communicates. That is to say, the two ends of the cavity where the bearing is installed in the bearing seat are respectively equipped with a bearing 3 and a sealing ring 6, and the cavity (cavity) between the bearing 3 and the sealing ring 6 is the oil cavity 4 in the present invention, or the bearing Bearings 3 are installed at both ends of the cavity where the bearing is mou...

Abstract

The invention relates to a sealed lubricate system of the main axle of metallic wet abrasive band grinder and relative method. Wherein, the bearing and sealing ring inside the bearing base or the chamber between two bearings is the oil chamber, whose wall has oil inlet channel. It has the advantages that: the oil chamber uses oil steam that generated by high-speed rotation of bearing to positive-pressure seal the bearing and sealing ring, which is not used in former technique and solves the problem that the small metallic particles of wet abrasive band grinder fall into the bearing; the oil feeding system and the oil inlet channel continuously supply lubricant to the oil chamber of bearing base, to confirm the lubricant of high-speed rotational bearing and prolong the service life which is 10 times before.

Description

Technical field: [0001] The invention relates to a sealing lubricating structure and a sealing lubricating method for a bearing of a wet-type abrasive belt grinder, and belongs to the field of manufacturing the sealing lubricating structure and the sealing lubricating method of the wet-type abrasive belt grinder bearing. Background technique: [0002] The metal wet abrasive belt grinding machine produced by the applicant has a bearing on the main shaft sleeve of the grinding machine, and the bearing is located in the bearing seat. Its shortcomings: First, the working environment of the metal wet belt grinder has both water and tiny grinding metal particles. The tiny metal particles and sewage are in the working process of the metal wet belt grinder. , the spindle bearing of the abrasive belt grinder cannot intrude the fine metal particles and cutting fluid into the bearing seat during the high-speed rotation process. If the fine metal particles cannot be effectively prevente...
