The utility model discloses a bearing bush for a squeezer, which is formed by sintering high-lubricity powder copper alloy, has no air holes and sand holes inside, and improves the wear resistance and the lubricating strength of the bearing bush; the upper semi-cylinder and the lower semi-cylinder are internally provided with oil storage tanks, so that the self-lubricating property is excellent; and the side surface of the bearing bush is in arc contact with the end surface of the roll shaft, so that the contact area is increased, and the friction resistance is reduced. Therefore, the service life of the bearing bush of the presser is greatly prolonged.
Description
Technical Field
The utility model relates to an axle bush, concretely relates to axle bush for four-roll squeezer.
Background
The bearing bush is the contact part of the sliding bearing and the shaft neck, is in the shape of a tile-shaped semi-cylindrical surface and is very smooth. The existing bearing bush is made of common copper alloy casting materials, casting defects such as sand holes, air holes and the like exist on the surface of the bearing bush after turning, and under the condition that a variable-load roll shaft of a squeezer rotates, the bearing bush generates high temperature due to direct friction between the bearing bush and a rotating shaft, so that the lubrication and the wear resistance are poor, the abrasion is serious, and the service cycle is short.
In order to solve the problem of poor lubricating property and wear resistance, the conventional presser bearing bush is lubricated by external lubrication without self-lubrication, and once the external lubrication is insufficient or untimely, the bearing bush is worn in a short time.
SUMMERY OF THE UTILITY MODEL
For solving the poor problem of ordinary axle bush lubricity, the utility model provides an axle bush for four-roll press that lubricity is good, wearability is good.
The utility model provides a following technical scheme:
bearing bush for four-roller press, including the cylinder, the both sides face of cylinder is formed with the flange, the cylinder comprises the semicolumn of upper and lower two halves symmetry, all is equipped with the oil storage tank unanimous with the roller direction of rotation in upper semicolumn, the lower semicolumn, still be equipped with the oil filler point on the lateral wall of upper semicolumn, the oil storage tank middle part of the below is aimed at to the oil filler point, and the cylinder medial surface of bearing bush is formed with the torus.
Furthermore, the bearing bush is formed by sintering powder copper alloy.
Furthermore, a stop groove is arranged at the flange of the end surface of the bearing bush.
Furthermore, the contact surface of the upper semi-cylinder and the lower semi-cylinder is provided with an installation screw hole.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a bearing bush for a squeezer, which is formed by sintering high-lubricity powder copper alloy, has no air holes and sand holes inside, and improves the wear resistance and the lubricating strength of the bearing bush; the upper semi-cylinder and the lower semi-cylinder are internally provided with oil storage tanks, so that the self-lubricating property is excellent; and the side surface of the bearing bush is in arc contact with the end surface of the roll shaft, so that the contact area is increased, and the friction resistance is reduced. Therefore, the service life of the bearing bush of the presser is greatly prolonged.
Drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a side view of fig. 1.
In the figure: 1. a cylinder 11, an upper half cylinder 12 and a lower half cylinder; 2. a flange; 3. an oil storage tank; 4. an oil filler hole; 5. mounting a screw hole; 6. a stopper groove; 7. a torus.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-2, the utility model discloses a bearing bush for four-roller press, including cylinder 1, the both sides face of cylinder 1 is formed with flange 2, cylinder 1 comprises the halfcylinder of upper and lower two halves symmetry, first halfcylinder 11, all be equipped with the oil storage tank 3 unanimous with the roller direction of rotation in the lower halfcylinder 12, still be equipped with oil filler point 4 on first halfcylinder 11's the lateral wall, oil filler point 4 is to 3 middle parts of oil storage tank of below, directly get into the oil storage tank after making things convenient for the oiling, the oil storage tank is unanimous with the roller direction of rotation, the bearing bush can both be lubricated like this in whole working process. Inject lubricating oil in the oil filler point 4, through the oil storage tank 3 that distributes in last semi-cylinder 11, lower semi-cylinder 12, can be with the even internal surface of attaching to at cylinder 1 of oil, when roller and axle bush contact and direct friction, can fully lubricate, this kind of self-lubricating mode only needs to inject lubricating oil in oil filler point 4, just can reach long-term lubricated effect.
The bearing bush is formed by sintering high-lubricity powder copper alloy, and no air holes or sand holes exist in the bearing bush, so that the wear resistance and the lubricity of the bearing bush are improved.
The inner side surface of the cylinder 1 of the bearing bush is provided with the circular ring surface 7, so that the side surface of the bearing bush is in arc contact with the end surface of the roll shaft, the contact area is increased, and the friction resistance is reduced.
The contact surfaces of the upper semi-cylinder 11 and the lower semi-cylinder 12 are provided with mounting screw holes 5, and the upper semi-cylinder and the lower semi-cylinder are connected through fasteners. And the middle split surface of the bearing bush is provided with a mounting screw hole for hoisting, so that hoisting and mounting of a protective cover are facilitated.
The end face flange 2 of the bearing bush is provided with a stop groove 6 to prevent the bearing bush from rotating.
The utility model discloses a four-roll squeezer is with axle bush all is equipped with the oil storage tank 3 unanimous with the roller direction of rotation in the upper and lower semi-cylinder of axle bush, still is equipped with oil filler point 4 on the lateral wall of upper semi-cylinder 11, and this kind is as long as follow axle bush outer wall and pour into lubricating oil into, utilizes inside oil storage tank 3 to reach self-lubricating effect, effectively reduces the friction between axle bush and the pivot, and is lubricated more even. The problems of poor lubricating property, no wear resistance, easy corrosion and short service life of the common bearing bush are solved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
