Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, specifically to an auxiliary tooling for measuring the axial deformation of tapered roller bearings. Background Technology

[0002] As a key component in mechanical transmission, the axial deformation of single-row tapered roller bearings is an important indicator for evaluating bearing performance, service life, and design rationality.

[0003] Currently, there is a lack of dedicated and efficient auxiliary tooling for measuring the axial deformation of single-row tapered roller bearings. This leads to problems such as inaccurate positioning and uneven force during the measurement process, affecting the measurement accuracy and efficiency, and making it difficult to accurately assess the working condition and design rationality of the bearing. Therefore, designing an auxiliary tooling that can accurately and conveniently measure the axial deformation of single-row tapered roller bearings has become an urgent need in the field of machining and inspection. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary tooling for measuring the axial deformation of tapered roller bearings, so as to solve the problem that the existing technology lacks a dedicated and efficient auxiliary tooling for measuring the axial deformation of single-row tapered roller bearings, which leads to inaccurate positioning and uneven force during measurement, affecting the measurement accuracy and efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary tooling for measuring the axial deformation of tapered roller bearings, comprising a pressure sleeve, a bearing ring, a support base, and a dial indicator. The outer side wall of the pressure sleeve is provided with an annular boss in the middle. The bearing ring is interference-fitted to the bottom end of the pressure sleeve. The upper surface of the support base is provided with a groove for placing the bearing to be measured. The lower end face of the bearing ring abuts against the upper end face of the bearing to be measured. A bracket is provided on the support base. The dial indicator is fixed by the bracket, and its probe abuts against the upper end face of the annular boss on the pressure sleeve.

[0006] Furthermore, the top of the pressure sleeve is provided with a cylindrical positioning groove that mates with the press head of the press, and the bottom of the pressure sleeve is provided with a cylindrical step that mates with the inner diameter surface and the upper end surface of the bearing ring.

[0007] Furthermore, the diameter of the groove on the support base is the same as the outer diameter of the bearing to be tested.

[0008] This utility model has the following beneficial effects:

[0009] This invention provides an auxiliary tooling for measuring the axial deformation of tapered roller bearings. The pressure applied by the press is transmitted to the bearing under test, causing the bearing to deform axially. The displacement of the pressure sleeve is then accurately measured using a dial indicator, thereby indirectly obtaining the axial deformation measurement of the bearing. This facilitates specific statistical analysis of the axial displacement. The materials required for this invention are easy to purchase and process, saving costs and improving work efficiency.

[0012] like Figure 1 As shown, an auxiliary fixture for measuring the axial deformation of a tapered roller bearing includes a pressure sleeve 1, a bearing ring 2, a support base 3, and a dial indicator 4. The pressure sleeve 1 has an annular boss 5 in the middle of its outer side wall. The bearing ring 2 is interference-fitted to the bottom of the pressure sleeve 1. The upper surface of the support base 3 has a groove for placing the bearing 6 to be measured, which provides good positioning for the bearing 6 and ensures that it will not shift during measurement. The lower end face of the bearing ring 2 abuts against the upper end face of the bearing 6 to ensure a smooth force transmission path. A bracket 7 is provided on the support base 3, and the dial indicator 4 is fixedly mounted on the bracket 7 with its probe abutting against the upper end face of the annular boss 5 on the pressure sleeve 1. The support base 3 is mounted on the worktable of a press. The probe of the dial indicator 4 contacts the annular boss 5 on the pressure sleeve 1, enabling accurate measurement of the downward displacement of the pressure sleeve 1, which is the axial deformation of the bearing 6 to be measured.

[0013] The top of the pressure sleeve 1 is provided with a cylindrical positioning groove 8 that mates with the press head of the press machine. The pressure sleeve 1 mates with the press head of the press machine through the cylindrical positioning groove 8. The bottom of the pressure sleeve 1 is provided with a cylindrical step that mates with the inner diameter surface and the upper end surface of the bearing ring 2.

[0014] The diameter of the groove on the support base 3 is the same as the outer diameter of the bearing 6 to be tested.

[0015] The specific operation process of this utility model is as follows:

[0016] During measurement, first adjust the support base 3 to contact the worktable, and align the pressure sleeve 1 with the press head to press the bearing 6 to be tested into the groove of the support base 3, so that the upper end face of the bearing 6 to be tested abuts against the lower end face of the bearing ring 2. Then, lower the press protective cover, control the press to apply the rated pressure, and the pressure sleeve 1 moves down. Read the axial deformation displacement on the dial indicator 4. After releasing the pressure, remove the bearing 6 to be tested. Through physical and chemical testing, determine whether the bearing has reached the maximum axial deformation, and evaluate the bearing's working condition based on the measured values ​​to verify the rationality of the bearing design.
