Detailed Description
The high-efficiency lubricating ball stud of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.
Example 1
The embodiment provides a ball stud with lubricating grease flowability, wherein two X-shaped crossed grooves are cut on the spherical surface of the ball stud in the prior art, the cross section of each groove is semicircular, the diameter of each groove is 1-2 mm, a small amount of lubricating grease can be reserved, and the flowability of the lubricating grease on the surface of the ball stud is provided. A counter bore is drilled inwards at the bottom of the ball head along the axial direction of the ball rod to serve as an oil storage cavity and store a certain amount of lubricating grease, and through holes with the diameter of 1-2 mm are respectively drilled at the intersection of the grooves and in the orthogonal direction of the grooves to form through hole oil ducts, so that the lubricating grease in the counter bore can flow with the outside conveniently.
Specifically, as shown in fig. 4-6, the high-efficiency lubrication ball stud of the present embodiment includes a ball head 100 and a pin shaft 200, a necking portion 300 is disposed between the ball head 100 and the pin shaft 200, and the ball head 100, the pin shaft 200, and the necking portion 300 may be an integrally formed structure. A counterbore is formed along the bottom of the ball 100 to form a reservoir 150, and the reservoir 150 is preferably an axisymmetric structure centered on the axis of the ball stud, such as a cylinder centered on the axis of the ball stud. The ball head 100 is provided with a first through-hole oil passage 110 and a second through-hole oil passage 120 which communicate the outer surface of the ball head with the oil storage cavity 150, the first through-hole oil passage 110 and the second through-hole oil passage 120 are both perpendicular to the axial direction of the ball head pin, and as a preferred example, the first through-hole oil passage 110 and the second through-hole oil passage 120 are also perpendicular to each other. A first groove 130 and a second groove 140 are disposed on the outer surface of the ball head 100, the first groove 130 and the second groove 140 intersect on the outer surface of the ball head 100 in an "X" shape, as shown in the figure, an intersection of the first groove 130 and the second groove 140 is located at an oil outlet of the second through-hole oil passage 120 on the outer surface of the ball head 100 (of course, the intersection may also be disposed at an oil outlet of the first through-hole oil passage 110, and the first through-hole oil passage 110 and the second through-hole oil passage 120 are only for convenience of description, and there is no substantial structural difference therebetween). In this embodiment, the oil storage cavity 150 may additionally store grease to ensure that the ball head is lubricated by grease at the ball head portion in any direction, the through- hole oil ducts 110 and 120 provide internal and external channels for connecting the ball head, and the external oil outlets are located in the two grooves 130 and 140 distributed in the shape of an "X", so that the grooves on the surface of the ball head can increase the storage and flow of grease at the spherical surface portion, thereby improving the lubrication effect.
