Description

Technical Field

[0001] The invention relates to the field of mechanical technology, in particular to a spiral wear-resistant hanging bearing. Background Art

[0002] Screw conveyors rely on the rotation of spiral blades to propel materials. When a screw conveyor's conveying length is too long, the screw shaft can collapse due to material factors. Therefore, when a screw conveyor is too long, the longer shaft is disconnected and a hanging bearing is added in between to prevent excessive wear on the screw conveyor caused by the collapse of the shaft. Using unmodified, standard hanging bearings requires frequent replacement, typically once a month. This impacts production, increases costs, increases employee labor intensity and safety risks, and reduces equipment efficiency.

[0003] Of course, in order to solve this problem, the existing technology has also proposed corresponding means to solve it, such as a sealed structure screw conveyor hanging bearing with application number: CN200720095424.6. Since the utility model designs the hanging bearing as a symmetrical structure of left and right parts, its disadvantage is that because the overall single bearing is connected to the axis and installed structure, it does not take into account the vibration and deformation of the screw conveyor during operation, and the axis deviation. Utility Model Content

[0004] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages to be described hereinafter.

[0005] In order to achieve these purposes and other advantages according to the present invention, a spiral wear-resistant hanger bearing is provided, comprising:

[0006] Tile sets;

[0007] The upper half of the Y-shaped bearing seat is connected to the lower end of the bushing;

[0008] A U-shaped hanging bearing, the upper end of which is detachably connected to the bushing, and a lower end of the U-shaped hanging bearing is provided with a lower half of a Y-shaped bearing seat via a U-shaped reinforcement member;

[0009] A self-lubricating bearing fixed to the upper half of the Y-shaped bearing seat and the lower half of the Y-shaped bearing seat;

[0010] A rotating shaft, which is coaxially connected to the self-lubricating bearing for rotation, and double-lip skeleton oil seals are provided at both ends of the rotating shaft;

[0011] The blade covers are fixed at both ends of the rotating shaft.

[0012] Preferably, the U-shaped upper end of the upper half of the Y-shaped bearing seat is fixed to the bushing, a support plate is provided between the U-shaped upper end and the bushing, and the lower end is fixed to the self-lubricating bearing, which is placed relative to the lower half of the Y-shaped bearing seat at a certain distance.

[0013] Preferably, the U-shaped hanging bearing passes through the upper half of the Y-shaped bearing seat and is fixed to the bushing by bolts, and the lower end of the U-shaped hanging bearing is fastened with a U-shaped reinforcement, which fixes the U-shaped hanging bearing to the lower half of the Y-shaped bearing seat by tightening bolts.

[0014] Preferably, the self-lubricating bearing is interference fit with the upper half of the Y-shaped bearing seat and the lower half of the Y-shaped bearing seat.

[0015] Preferably, the double-lip skeleton oil seal is an O-type structure.

[0016] Preferably, the blade cover is fixed to the rotating shaft by a hexagon socket guide screw.

[0017] The utility model has at least the following beneficial effects:

[0018] The hanging bearing body is a U-shape formed by bending the steel plate. The upper end is fixed to the bushing by bolts, and the lower end is fixed to the lower half of the Y-shaped bearing seat by a reinforcement, which can better play the role of self-alignment and wear resistance.

[0019] Both ends of the rotating shaft are connected with blade covers and can drive the blade covers to rotate around the axial direction of the rotating shaft. The rotating shaft extends into the blade cover so that the rotating shaft is in close contact with the blade cover.

[0020] Self-lubricating bearings require little or no maintenance during use, and have good wear resistance, low friction coefficient, long service life, and appropriate elasticity and plasticity, which can distribute stress on a wider contact surface and improve the bearing's load-bearing capacity. The self-lubricating bearings and the bearing seats have an interference fit, so that the self-lubricating bearings can only perform self-lubricating relative motion driven by the rotating shaft, reducing the useless rotation of the self-lubricating bearings and improving the operation of the screw conveyor.

[0021] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a detailed description of this experimental model with reference to the accompanying drawings:

[0029] Figure 1-4 The experimental novel embodiment shown provides a spiral wear-resistant hanging bearing, comprising:

[0030] Tile set 1;

[0031] The upper half 2 of the Y-shaped bearing seat is connected to the lower end of the bushing 1;

[0032] A U-shaped hanging bearing 9, the upper end of which is detachably connected to the bushing 1, and a Y-shaped bearing seat lower half 3 is provided in the lower end of the U-shaped hanging bearing 9 via a U-shaped reinforcement 12;

[0033] A self-lubricating bearing 4, which is fixed to the upper half 2 of the Y-shaped bearing seat and the lower half 3 of the Y-shaped bearing seat;

[0034] A rotating shaft 5 is coaxially connected to the self-lubricating bearing 4 for rotation, and double-lip skeleton oil seals 7 are provided at both ends of the rotating shaft 5;

[0035] The blade covers 6 are fixed at both ends of the rotating shaft 5 .

[0036] Working principle:

[0037] A spiral wear-resistant hanging bearing, wherein blade covers 6 are connected to both ends of a rotating shaft 5, and the blade covers 6 are driven to rotate around the axial direction of the rotating shaft 5. The rotating shaft 5 extends into the blade covers 6, so that the rotating shaft 5 and the blade covers 6 are in close contact;

[0038] Furthermore, double-lip skeleton oil seals 7 are provided at both ends of the blade cover 6. The double-lip skeleton oil seals 7 block the entry of external dust while preventing leakage of internal lubricating oil. The self-lubricating bearing 4 interferes with the upper half 2 of the Y-shaped bearing seat and the lower half 3 of the Y-shaped bearing seat, so that the self-lubricating bearing 4 can only perform self-lubricating relative motion driven by the rotating shaft 5, reducing the useless rotation of the self-lubricating bearing and improving the operation of the screw conveyor.

[0039] Furthermore, the upper half 2 of the Y-shaped bearing seat is welded to the bushing 1, and the lower half 3 of the Y-shaped bearing seat is fixed to the upper half through the U-shaped hanging bearing 9, and a reinforcement 12 is provided at the lower end of the U-shaped hanging bearing to prevent deformation and vibration during operation.

[0040] As described in the above scheme, the upper half 2 of the Y-shaped bearing seat has its U-shaped upper end fixed to the sleeve 1, a support plate 11 is provided between the upper end of the U-shaped bearing seat and the sleeve 1, and the lower end is fixed to the self-lubricating bearing 4, and is placed relative to the lower half 3 of the Y-shaped bearing seat at a certain distance.

[0041] Working principle: The support plate 11 is arranged between the bushing 1 and the upper half 2 of the Y-type bearing seat to disperse the force and reduce the deformation and offset that may occur when the Y-type bearing seat is subjected to excessive force.

[0042] As described in the above scheme, the U-shaped hanging bearing 9 passes through the upper half 2 of the Y-shaped bearing seat and is fixed to the bushing 1 by bolts 10. The lower end of the U-shaped hanging bearing 9 is fastened with a U-shaped reinforcement 12, which fixes the U-shaped hanging bearing 9 to the lower half 3 of the Y-shaped bearing seat by tightening bolts 13.

[0043] Working principle: The hanging bearing body is a U-shape formed by bending the steel plate, which saves costs. The lower end of the U-shaped hanging bearing 9 is punched through, and the U-shaped reinforcement 12 is connected and fixed to the U-shaped hanging bearing 9 and the lower half 3 of the Y-shaped bearing seat by bolts and screws 13, which better plays the role of self-alignment and wear resistance.

[0044] As described in the above solution, the self-lubricating bearing 4 is interference fit with the Y-shaped bearing seat upper half 2 and the Y-shaped bearing seat lower half 3.

[0045] Working Principle: The self-lubricating bearing 4 requires little or no maintenance during use, and features excellent wear resistance, a low coefficient of friction, and a long service life. Its moderate elastic-plastic properties distribute stress over a wide contact surface, improving the bearing's load-bearing capacity. This allows the self-lubricating bearing 4 to move in self-lubricating relative motion only under the drive of the rotating shaft 5, reducing wasted rotation and improving the operation of the screw conveyor.

[0046] As described in the above solution, the double-lip skeleton oil seal 7 is an O-type structure.

[0047] Working principle: The double-lip skeleton oil seal 7 ensures that the rotating shaft 5 is isolated from the external environment to prevent the lubricating oil from leaking. The lubricant used in the hanging bearing cannot overflow to avoid contaminating the conveyed materials. At the same time, the auxiliary lip of the double-lip skeleton oil seal plays a dust-proof role to prevent external dust and impurities from entering the interior of the machine.

[0048] As described in the above solution, the blade cover 6 is fixed to the rotating shaft 5 by the hexagon socket guide screw 8.

[0049] Working principle: To prevent the blade cover 6 from deviating from the rotation axis when rotating at high speed, the hexagon socket guide screw 8 is passed through the blade cover 6 and the rotating shaft 5 to ensure smooth rotation. The rotating shaft 5 extends into the blade cover 6, and the bolt 8 is used to fix the rotating shaft 5 to the blade cover 6. In this way, the rotating shaft 5 avoids wear when rotating, extends the service life of the hanging bearing, and saves production costs.

[0050] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
