Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, 2 and 3, the axial thrust bearing convenient for filling lubricating oil of the present embodiment includes an outer ring 1 and an inner ring 2 which are coaxial, a plurality of rollers 3 are disposed between the outer ring 1 and the inner ring 2, a bottom cover 4 and an upper cover 5 which are rotatably connected with the outer ring 1 and tangent to the rollers 3 are respectively disposed on two sides of the outer ring 1, and an oil filling nozzle 6 capable of filling lubricating oil to the rollers 3 is disposed on an outer circumferential surface of the outer ring 1; a snap ring 11 protruding inwards is arranged on one side of the outer ring 1, and the section of the bottom cover 4 is T-shaped; a clamping groove 12 is formed in the other side of the outer ring 1, and the upper cover 5 is rotatably connected with the outer ring 1 through a clamping spring 7; the clamp spring 7 is an open circular ring.
The oil filling nozzle 6 is arranged on the outer circumference of the outer ring 1, so that lubricating oil, namely lubricating grease, can be conveniently filled into the space between the outer ring 1 and the inner ring 2 from the oil filling nozzle 6; the outer diameters of the bottom cover 4 and the upper cover 5 are smaller than that of the outer ring 1, the bottom cover 4 is arranged from one side of the outer ring 1, the bottom cover 4 is assembled by mutual interference of a T-shaped boss of the bottom cover 4 and the snap ring 11, then the roller 3 is arranged, and the snap spring 7 is clamped into the outer circumference of the upper cover 5, because the snap spring 7 is an open ring, the snap spring 7 can be kneaded to reduce the outer diameter so as to clamp the snap spring 7 into the snap groove 12, and therefore the upper cover 5 is assembled to the outer ring 1; as can be seen from the assembly mode, the bottom cover 4 and the upper cover 5 are both rotationally connected with the outer ring 1.
The bearing is a pure axial thrust bearing, namely only subjected to axial force, so that the bottom cover 4 and the upper cover 5 both protrude out of the outer ring 1 towards two sides, and an external mechanical structure is only abutted against the bottom cover 4 and the upper cover 5; for this reason, the width of the inner ring 2 is smaller than the distance between the bottom cover 4 and the upper cover 5, and the outer ring 1 and the inner ring 2 of the bearing play a role of matching the bottom cover 4 and the upper cover 5 to seal the roller, and are not stressed.
In order to ensure that the bearing can bear higher pressure, the number of the rollers 3 is increased on the conventional basis, 21 rollers are adopted in the embodiment, and when the rollers are installed, lubricating grease needs to be added simultaneously, and then the upper cover 5 is packaged.
The roller 3 may be a cylinder or a cone, and in order to increase the number of the rollers 3 to be mounted, in this embodiment, the roller 3 is in a truncated cone shape, and the end of the roller 3 with the smaller diameter faces inwards. Since the rollers 3 are to support the lower cover 4 and the upper cover 5, that is, the rollers 3 are not only to rotate around their own axes but also to move circularly along with the lower cover 4 and the upper cover 5, a plurality of the rollers 3 are arranged in a circle along the concentric circle of the outer ring 1, and the axes of the rollers 3 are orthogonal to the axis of the outer ring 1.
In order to facilitate the shaft to pass through the bearing, the inner diameters of the bottom cover 4 and the upper cover 5 are equal, and the inner diameter of the inner ring 2 is not smaller than the inner diameter of the bottom cover 4.
In order to prevent the filler neck 6 from entering dust, the filler neck 6 is provided with a filler cap 8.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
