Description

Technical Field

[0001] The utility model relates to the technical field of pear disc bearings, in particular to a maintenance-free pear disc bearing unit. Background Art

[0002] Bearings are also used in pear-spinning equipment (such as the pear-spinning devices in some agricultural machinery or specific industrial pear-spinning equipment). Bearings are mechanical components used to support and rotate shafts, reducing friction and supporting the load on the shaft, making the shaft rotate more smoothly. They are widely used in various equipment and machinery, including automobiles, trains, ships, wind turbines, industrial machinery, etc. Bearings basically consist of an inner ring, an outer ring, rolling elements, and a cage. The inner and outer rings are made of high-strength steel or cast iron. The rolling elements can be various shapes such as balls, rollers, needles, cones, etc. The cage is used to maintain the position of the rolling elements.

[0003] In pear tray-related equipment, the working environment of bearings is often harsh, and they may face various adverse factors such as dust, moisture, high temperature or low temperature. Traditional bearing units are more prone to failure in such an environment and are more difficult to maintain. Utility Model Content

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a maintenance-free pear disk bearing unit, comprising a bearing outer ring,

[0006] and an auxiliary component arranged at a side position of the bearing outer ring;

[0007] The auxiliary component includes a sealing mechanism arranged at a side position of the bearing outer ring;

[0008] A lubrication mechanism is provided on the side of the bearing outer ring.

[0009] Preferably, the inner wall of the outer ring of the bearing is provided with balls in contact, and the side wall of the balls is provided with balls in contact with the inner ring of the bearing.

[0010] Preferably, the sealing mechanism includes a positioning plate, the side wall of the positioning plate is arranged in contact with the side wall of the bearing inner ring, and a positioning bolt is rotatably installed on the inner wall of the positioning plate. One end of the positioning bolt movably passes through the inner wall of the positioning plate and extends to the inner wall of the circular groove provided on the side wall of the bearing inner ring, and is threadedly connected to the inner wall of the circular groove. A main sealing ring is fixedly installed on the side wall of the positioning plate, and an auxiliary sealing ring is fixedly installed on the side wall of the main sealing ring.

[0011] Preferably, the side wall of the main sealing ring is arranged in contact with the side wall of the bearing inner ring, and the side wall of the auxiliary sealing ring is arranged in contact with the side wall of the bearing inner ring.

[0012] Preferably, the side wall of the main sealing ring is rotatably connected to the inner wall of the bearing outer ring, and the side wall of the main sealing ring is rotatably connected to the inner wall of the bearing outer ring.

[0013] Preferably, the lubrication mechanism includes a sealing plug, the side wall of the sealing plug is slidably connected to the inner wall of the circular hole opened on the side wall of the outer ring of the bearing, an arc-shaped bin is fixedly installed on one end of the sealing plug, an air inlet pipe is fixedly installed on the side wall of the arc-shaped bin, and a sealing cover is threadedly connected to the side wall of the air inlet pipe.

[0014] Preferably, the inner wall of the air inlet pipe is connected to the interior of the arc-shaped bin, the inner wall of the arc-shaped bin is connected to the interior of the sealing plug, and the inner wall of the sealing plug is connected to the interior of the bearing outer ring.

[0015] The utility model provides a maintenance-free pear disk bearing unit. It has the following beneficial effects:

[0016] (1) The utility model allows the operator to install the auxiliary sealing ring and the main sealing ring. The auxiliary sealing ring is installed in the gap between the outer ring of the bearing and the inner ring of the bearing. Then the operator rotates the position of the positioning bolt. The position of the main sealing ring can be stabilized by the positioning bolt. The main sealing ring adopts a composite structure of rubber and metal, has good elasticity and sealing performance, and can effectively prevent dust, moisture and other impurities from entering the bearing. The sealing effect is further enhanced by the auxiliary sealing ring. When the pear disk bearing unit starts working, the bearing body is subjected to various forces transmitted by the pear disk, including axial force and radial force. The sealing mechanism effectively blocks the entry of external impurities and protects the internal structure of the bearing, solving the problem that the working environment of the bearing in the pear disk-related equipment is often relatively harsh and may face various adverse factors such as dust, moisture, high temperature or low temperature. Traditional bearing units are more likely to fail in such an environment and are more difficult to maintain.

[0017] (2) In the present invention, when the operator rotates the position of the sealing cover, the sealing cover can be disassembled and grease can be added to the inner wall of the arc-shaped bin. During the operation of the bearing, due to temperature changes and centrifugal force, the grease will automatically flow from the arc-shaped bin through the sealing plug and slowly replenished to the bearing raceway, thereby achieving automatic lubrication and improving the service life of the bearing.
