Description

Technical Field

[0001] The utility model relates to the technical field of vibration tables, in particular to a high-pressure guide bearing for a horizontal sliding table of a vibration table. Background Art

[0002] A vibration table is a reliability testing device that simulates the various environments a product encounters during manufacturing, assembly, transportation, and use, to determine its ability to withstand environmental vibrations. The vibration table's horizontal slide, the part of the vibration table used to support the test piece, is required to withstand significant weight and sliding friction. Therefore, for ease of use, the vibration table's horizontal slide is typically specially designed during manufacturing. Current vibration table slides are prone to vibrating in a lateral direction perpendicular to the direction of movement during actual use, adversely affecting test results. Therefore, a high-pressure guide bearing for the vibration table's horizontal slide was developed. Utility Model Content

[0017] like Figure 1-Figure 3 As shown, a high-pressure guide bearing of a vibrating table horizontal slide comprises two symmetrically arranged bearing brackets 1, with a sliding shaft 2 installed between the two bearing brackets 1. Specifically, the upper parts of both ends of the sliding shaft 2 are fixedly connected to the two bearing brackets 1 by cylindrical head hexagon socket screws 6.

[0018] The sliding shaft 2 is equipped with a bearing body 3, the specific model of which is a 710 bearing. The center hole of the bearing body 3 is in clearance with the sliding shaft 2, and the bearing body 3 is provided with an oil inlet hole 4 that penetrates the wall thickness thereof. An oil film is formed between the inner peripheral wall of the bearing body 3 and the outer peripheral wall of the sliding shaft 2.

[0019] The upper part of the bearing body 3 is fixedly connected to the horizontal slide of the vibration table. Specifically, four threaded connection holes 5 are opened near the corners of the upper part of the bearing body 3, and it is fixedly connected to the horizontal slide by connecting screws compatible with the threaded connection holes 5.

[0020] In this embodiment, the two bearing brackets 1 are made of aluminum alloy 6061, and the sliding shaft 2 and the bearing body 3 are made of aluminum alloy 7075, and are anodized.

[0021] This utility model consists of a bearing body, a sliding shaft, and brackets at both ends. The brackets are fixed to the sliding shaft. High-pressure (pressure 2500Ps i) lubricating oil is injected into the gap between the bearing body and the sliding shaft through the oil inlet, forming an oil film, allowing the bearing to slide smoothly along the sliding shaft. At this time, the horizontal slide on the upper surface of the bearing can carry a certain weight of test products. In specific use, the number of the bearing bodies and the sliding shaft is multiple, and multiple 710 bearings are fixed to the same base plate. The height of the multiple bearing bodies and the straightness of the sliding shafts are consistent. When the horizontal slide is installed on the upper surface of the bearing, it has the characteristics of high load capacity and low resistance, and can suppress the lateral movement of the horizontal slide.
