Description

Technical Field

[0001] The utility model relates to the technical field of bearing accessories, in particular to the technical field of a reinforced grease leakage-proof end cover structure. Background Art

[0002] Bearings are an important component in modern mechanical equipment. They are components that fix and reduce the load friction coefficient during mechanical transmission. When other components produce relative motion on the shaft, the bearing is used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Its main function is to support the mechanical rotating body, reduce its friction coefficient during movement, and ensure its rotation accuracy. Bearings are generally composed of an outer ring, an inner ring, and rolling elements located between the inner and outer rings. The sealing performance is poor. During the rotation of the bearing, the lubricating grease inside the bearing is easily leaked due to poor sealing. External dust, moisture and foreign matter can easily invade the inside of the bearing, causing bearing wear, affecting the normal use of the bearing, and reducing the service life of the bearing. In order to better protect the bearing, it is necessary to propose the research and development of a reinforced anti-leakage grease end cover structure. Summary of the Invention

[0003] The purpose of this utility model is to solve the problems in the prior art and propose a reinforced anti-leakage grease end cover structure, which can prevent the grease in the bearing seat from overflowing and external heavy pollutants and dust from invading the interior, thereby greatly improving the service life of the bearing in a heavy pollutant environment.

[0004] To achieve the above-mentioned purpose, the utility model proposes a reinforced anti-leakage grease end cover structure, including an end cover body, an axial hole, an outer bending reinforcement ring, an inner bending reinforcement ring, a folded reinforcement ring edge, a rubber-coated positioning ear, a bolt hole and an arc-shaped sealing strip. The center position of the end cover body is axially penetrated by an axial hole, the outer side of the axial hole is surrounded by an outer bending reinforcement ring, the outer side of the outer bending reinforcement ring is surrounded by an inner bending reinforcement ring, the outer side of the inner bending reinforcement ring is surrounded by a folded reinforcement ring edge, six rubber-coated positioning ears are evenly arranged on the outer side of the folded reinforcement ring edge, a bolt hole is axially penetrated in the rubber-coated positioning ear, and the outer side surface of the folded reinforcement ring edge is surrounded by two concentric arc-shaped sealing strips.

[0005] Preferably, a rubber sealing layer is evenly adhered to the right side of the end cover body.

[0006] Preferably, the end cover body, the outer bending reinforcement ring, the inner bending reinforcement ring, the folded reinforcement ring edge and the rubber-coated positioning ear are an integrated structure.

[0007] Preferably, the outer bending reinforcement ring is bent obliquely to the left, and the inner bending reinforcement ring is bent obliquely to the right.

[0008] Preferably, a plane ring edge is extended outside the folded reinforcement ring edge, and the arc-shaped sealing strip is adhered to the plane ring edge.

[0009] Preferably, the axis center lines of the end cover body, the axial hole, the outer bending reinforcement ring, the inner bending reinforcement ring and the folded reinforcement ring edge are located on the same straight line.

[0010] Preferably, the cross-section of the arc-shaped sealing strip is semicircular, and the thickness of the two arc-shaped sealing strips is the same.

[0011] The beneficial effects of the present invention are as follows: the present invention combines the end cover body, the shaft hole, the outer bending reinforcement ring, the inner bending reinforcement ring, the folded reinforcement ring edge, the rubber-coated positioning ear, the bolt hole and the arc-shaped sealing strip together. After experimental optimization, the outer bending reinforcement ring and the inner bending reinforcement ring cooperate with each other to position the shaft hole in the hole of the bearing seat, which plays a positioning role. The six rubber-coated positioning ears of the 3mm thick end cover are locked with the bearing seat with bolts, so that the product will not be deformed due to assembly, and the sealing effect between the product and the bearing seat is guaranteed to achieve the ideal effect. The end cover body part in contact with the bearing seat plane is provided with two protruding arc-shaped sealing strips, which can fit linearly with the bearing seat plane, effectively prevent external pollutants from entering the bearing, ensure the intact function of the bearing, and prevent grease in the bearing seat from overflowing, thereby achieving multiple sealing effects.
