[0005] The benefits of adopting the above technical solution are: the operator installs the bearing to be tested on the bushing and fixes the bushing on the fixed seat, and then drives the bearing to be tested to operate through the driving member to simulate the actual operating conditions of the bearing. When the bearing runs at high speed, the detection component in the bushing will detect the operating indicators of the bearing at high speed, thereby meeting the purpose of multi-directional detection. At the same time, the loading force applied by the external loading system can be applied to the bearing to be tested through the transmission member, thereby simulating the stress conditions of the bearing during actual operation, thereby improving the detection range; the detection efficiency is improved by the setting of the above technology, and the operation is simple. It only needs to install the bearing to be tested on the bushing and fix the bushing on the fixed seat. The above technology simulates the actual operating conditions and stress conditions of the bearing, thereby improving the detection accuracy.

The above technical setting improves the accuracy and detection range of the bearing detection, so as to achieve the purpose of multi-directional detection; the method of installing the bearing to be tested into the mounting hole in the above technology is common knowledge, so its specific installation method will not be described in detail.

Because they are existing technologies, the specific detection methods, structures and functions of the two are not described in detail; the vibration sensor in the above technology can be installed on an external tooling or bracket according to installation requirements, and the detection end of the vibration sensor is in contact with the outer peripheral wall of the bushing to detect the vibration parameters generated when the bearing to be tested is running.

[0009] The benefits of adopting the above technical solution are: before the bearing to be tested needs to be driven, the operator aligns the drive flange with the external drive motor flange, and then uses an external high-strength nylon rope to bind and connect the round hole with the embedded hole on the external drive motor flange, thereby realizing the connection between the external drive motor flange and the drive flange. In the above technology, the circular chamfer is set to avoid the breakage of the nylon rope rotating at high speed, thereby improving the connection strength between the drive flange and the external drive motor flange; in the above technology, the connection is improved by connecting with nylon rope to improve the connection strength between the two. At the same time, the use of nylon rope connection can increase the connection speed, thereby improving the disassembly and assembly efficiency, and compared with the traditional bolt connection, it can avoid the loosening or shaking of the bolts when the drive flange runs at high speed, resulting in failure of the connection between the drive flange and the external drive motor flange; the method of using nylon rope connection in the above technology is an existing technology, so the specific connection method will not be described in detail.
[0010] The utility model is further configured as follows: the fixing seat is composed of an upper cover and a lower cover, arc grooves are provided on the bottom wall of the upper cover and the top wall of the lower cover, the two arc grooves are combined to form a through hole for accommodating the linkage shaft, a number of connecting bolts are connected between the upper cover and the lower cover, and a number of mounting bolts are connected between the lower cover and the support seat.

[0013] The above technical solution is beneficial in that: the test bearing is set up to transmit the loading force applied by the external loading system to the linkage shaft through the test bearing, and the loading force is transmitted to the bearing to be tested through the linkage shaft. The setting of the test bearing improves the smoothness of the linkage shaft during rotation. At the same time, the loading force acting on the loading seat is transmitted to the linkage shaft through the test bearing, and then transmitted to the bearing to be tested through the linkage shaft, so as to achieve the purpose of applying the loading force to the bearing to be tested.
[0014] The utility model is further provided with: adjustment teeth for adjusting the loading point position on the loading seat applied by the external loading system are opened on the side walls of the loading seat along the opening direction of the loading seat; an adjustment hole is opened on the top wall of the loading seat; the support seat and the loading seat are detachably connected and an adjustment shaft is provided at the bottom of the support seat; an adjustment disk for inserting the adjustment hole is provided on the adjustment shaft; a first tooth groove is opened in an annular direction on the outer circumferential wall of the adjustment disk; a second tooth groove for mating and meshing with the first tooth groove is opened in an annular direction on the inner circumferential wall of the adjustment hole; a plurality of limit columns are arranged in an annular direction on the bottom wall of the loading seat; a plurality of the limit columns are distributed in an annular direction on the outer edge of the adjustment hole; a limit sleeve is threadedly connected to each of the limit columns, and the bottom wall of the limit sleeve is partially abutted against the top wall of the loading seat and the top wall of the adjustment disk respectively.
[0015] The benefit of adopting the above technical solution is that: when it is necessary to adjust the position of the loading force applied by the loading system, the eccentricity of the loading force acting on the bearing to be tested can be adjusted by adjusting the position of the loading point transmitted to the loading seat by the loading system, thereby simulating the bearing to be tested to be subjected to the tension of the rotating belt in actual operating conditions, thereby achieving the purpose of multi-directional detection.

Since a first tooth groove is circumferentially provided on the outer peripheral wall of the adjusting disk and a second tooth groove is circumferentially provided in the adjusting hole, the first tooth groove and the second tooth groove are engaged to achieve the limitation and fixation of the adjusting disk, and at the same time Due to the tooth setting of the tooth groove, the adjusting disk is rotated before being inserted to adjust the direction of the loading seat and then the direction of the bushing, thereby realizing eccentric loading of the loading force, that is, realizing the adjustment of the direction of the loading force. After the first tooth groove and the second tooth groove are plugged and engaged, the operator can screw in the limit sleeve and make the bottom wall of the limit sleeve partially abut against the top wall of the loading seat and the top wall of the adjusting disk respectively, thereby realizing the fixation of the adjusting disk in the adjusting hole, and preventing the adjusting disk from falling out of the adjusting hole along the axial direction of the adjusting hole; the above-mentioned technical setting is used to realize the adjustment of the loading direction and loading position of the loading force, thereby realizing the adjustment of the loading of the bearing to be detected, thereby improving the detection range and detection accuracy.
