Embodiment 1

[0025] Such as figure 1 with 2 As shown, a bushing testing device 1 includes:

[0026] Base 3 with a mounting ring 31 on the top of the base;

[0027] Hole seat 4, the hole seat 4 is arranged in the cavity of the mounting ring 31, one end of which extends out of the cavity of the mounting ring 31 to form a rotating drive end 41, and the outer surface of the hole seat 4 close to the rotating drive end 41 also includes a second A limit flange structure 42;

[0028] Two rolling bearings 61 and 62 respectively include an outer ring 611, an inner ring 612, an outer ring 621, and an inner ring 622. The rolling bearings 61 and 62 are installed between the mounting ring 31 and the hole seat 4, and the outer ring 611 and 621 is in contact with the inner wall of the mounting ring 31, the inner rings 612 and 622 are in contact with the outer wall of the socket 4, and one side of the inner ring 612 is in contact with the side of the first limiting flange structure 42; A spacer ring 63...

Embodiment 2

[0050] Such as Figure 4 As shown, a bushing testing device includes:

[0051] A rotary driving device, the rotary driving device includes a motor 121 and a rotating shaft 122 . Wherein, the rotating shaft 122 is a Z-shaped shaft, one end of the rotating shaft 122 is connected to the motor 121 , and the other end is connected to the rotating driving end 41 of the socket 4 . The axis of rotation of a transverse axis 1221 of the rotating shaft 122 coincides with the axis of the fixed shaft 9 .

[0052] Other settings of the bushing testing device are the same as in Embodiment 1.

[0053] When the bush testing device is in operation, the rotary drive device 11 drives the rotary shaft 122 to reciprocate at a certain angle. The rotating shaft 122 will drive the hole seat 4, the bush positioning seat 8 and the bush to be tested 13 installed in the space 83 for accommodating the bush to be tested to rotate in the rolling bearing. At the same time, the pressure loading device appl...

Abstract

The invention discloses a lining test device. The lining test device comprises a foundation, a rolling bearing mounted in a mounting ring of the foundation, a hole seat and a lining positioning seat,a fixing shaft penetrating through the lining positioning seat, a rotary driving device connected with a rotary driving end of the hole seat, and a pressure loading device used for applying pressure to the fixing shaft. The lining test device is advantaged in that borne load conditions of a lining in the internal actual work environment of an automobile seat skeleton structure transfer point can be simulated, and evaluation for wear conditions of the lining and estimation of service life of the lining and the work state of the lining in an automobile seat operation are facilitated.

Description

technical field [0001] The invention relates to a bush testing device. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements for the safety and comfort of car seats. As a wear-resistant part that provides motion lubrication in the seat height adjuster, the bushing directly determines the working performance, structural optimization design and service life of the seat height adjuster. [0003] In the prior art, the testing of bushing performance is mainly based on the standard testing of bushings. This standard test does not involve the influence of the actual working environment of the seat height adjuster on the performance of the bushing, and cannot truly reflect the changes in the performance of the bushing used for the seat height adjuster over time. Specifically, when the seat height adjuster is in a working environment, the bush inside it is subject to dynamic load from the seat for a long time...
