一种电机轴承耐久度测试装置

Abstract

本实用新型公开了一种电机轴承耐久度测试装置，包括测试台，其顶部安装有供待测电机轴承安装的轴承座以及安装有转轴的轴架；所述轴架固定设置，所述转轴水平转动安装于轴架，且通过驱动单元进行驱动转动；所述轴承座滑动设置，所述待测电机轴承可取出式固定安装于轴承座，且待测电机轴承与转轴共线对准设置，所述测试台在靠近轴承座位置处安装有工装单元，用于控制轴承座朝靠近或远离转轴方向移动，使待测电机轴承随轴承座移动而插配连接于转轴或者使待测电机轴承随轴承座移动而脱离出转轴。这种测试方式，能够实现待测电机轴承与转轴之间的快速连接与脱离，便于实际的测试工作。

Claims

1. An electric machine bearing endurance test apparatus, characterized by: The test bench (1) includes a bearing seat (3) for mounting the bearing (2) of the motor under test and a shaft bracket (5) for mounting the rotating shaft (4). The shaft bracket (5) is fixedly installed, and the rotating shaft (4) is horizontally rotatably mounted on the shaft bracket (5) and driven to rotate by a drive unit (6). The bearing seat (3) is slidably installed, and the bearing (2) of the motor under test is removably fixedly installed on the bearing seat (3). The bearing (2) of the motor under test and the rotating shaft (4) are collinearly aligned. The test bench (1) has a tooling unit (7) installed near the bearing seat (3) to control the bearing seat (3) to move towards or away from the rotating shaft (4).

2. A motor bearing endurance test apparatus as set forth in claim 1, characterized by: The bearing housing (3) includes a lower housing part (31) and an upper housing part (32). After the upper housing part (32) and the lower housing part (31) are combined, the middle part forms an installation port for the motor bearing (2) to be tested to be installed. The installation port is divided in half between the upper housing part (32) and the lower housing part (31). The upper housing part (32) and the lower housing part (31) are connected and fixed by screws after being combined.

3. A motor bearing endurance test apparatus as set forth in claim 1 wherein: The shaft frame (5) includes a front support seat (51) and a rear support seat (52), and the front and rear ends of the rotating shaft (4) are respectively supported by the front support seat (51) and the rear support seat (52).

4. The electric machine bearing endurance test apparatus of claim 1, wherein: The drive unit (6) includes a motor (61), which drives the rotating shaft (4) via a belt drive structure (62).

5. A motor bearing endurance test apparatus as set forth in claim 1 wherein: The tooling unit (7) includes a hydraulic cylinder (71), a push rod (72), and a square frame plate (73). The hydraulic cylinder (71), the push rod (72), and the bearing (2) of the motor to be tested in the bearing housing (3) are aligned and collinear. One end of the push rod (72) is fixedly connected to the movable end of the hydraulic cylinder (71). The square frame plate (73) is fixedly installed on the other end of the push rod (72) away from the hydraulic cylinder (71). The square frame plate (73) is fitted onto the bearing housing (3). Openings are provided on both the front and rear sides of the square frame plate (73) to avoid the insertion of the rotating shaft (4) and the bearing (2) of the motor to be tested.

6. A motor bearing endurance test apparatus as set forth in claim 1 wherein: The rotating shaft (4) is used to fix a conical sleeve (8) at one end for connecting with the bearing (2) of the motor to be tested. The conical sleeve (8) has a small end facing inward and a large end facing inward.

7. A motor bearing endurance test apparatus as set forth in claim 6 wherein: The conical sleeve (8) and the rotating shaft (4) are fixedly installed by countersunk screws.
