Description

Technical Field

[0001] This utility model relates to the technical field of rubber wheel testing, and in particular to a rubber wheel life testing device. Background Technology

[0002] We have a new product with a cast aluminum hub and a rubber outer ring, which are bonded together by vulcanization. The product has a working speed of 9 m / s and is used as a top roller guide shoe on an elevator. When the elevator is going up or down, the rollers roll on the guide rail to ensure smooth operation.

[0003] Existing rubber tire life testing devices, such as the rubber tire quality inspection testing device disclosed in utility model patent application number 202321036877.7, mainly include a base. Multiple electric push rods are symmetrically fixedly connected to the upper end of the base, and the upper output ends of the multiple electric push rods are fixedly connected to the same support seat. In use, a suitable testing friction plate is installed on the upper end of the support seat, and the tire to be tested is placed between two clamping plates. The dual-axis motor is started, driving two adjusting screws to rotate synchronously. Through the threaded engagement of the adjusting screws and the moving plate, the moving plate moves the clamping plates. The two clamping plates, together with the fixing pin, securely clamp the tire.

[0004] However, most existing testing devices are difficult to load on the rubber wheel, difficult to simulate the real working state of the rubber wheel, and difficult to guarantee the stability of the test speed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rubber wheel life testing device that can not only load the rubber wheel to be tested, but also adjust the test speed to simulate the real working state of the rubber wheel to the greatest extent.

[0006] This utility model discloses a rubber wheel life testing device, which includes a drive mechanism, a load mechanism, and a rubber wheel. The load mechanism is mounted on the drive mechanism and applies a load to the rubber wheel. The rubber wheel is mounted on the load mechanism for testing. The operator installs the rubber wheel to be tested onto the load mechanism, then applies a 240 kg counterweight to the load mechanism to apply pressure to the rubber wheel, ensuring that the rubber wheel reaches the working load. The drive mechanism is then activated to rotate the rubber wheel, and the lifespan of the rubber wheel is tested.

[0007] Preferably, the drive mechanism includes a base, a drive wheel bracket, a drive wheel, a variable frequency motor, and a belt. The bottom end of the base is connected to the ground. The drive wheel bracket is mounted on the base, and the drive wheel is rotatably mounted on the drive wheel bracket. The variable frequency motor is mounted on the ground, and the belt drive is installed between the drive wheel and the variable frequency motor. When the variable frequency motor is started, it drives the drive wheel to rotate via the belt. The drive wheel drives the rubber wheel to rotate, and the service life of the rubber wheel is tested.

[0008] Preferably, the variable frequency motor is equipped with a speed controller; the operator measures the rotational speed of the drive wheel with a tachometer, and then uses the speed controller to adjust the output speed of the variable frequency motor so that the rotational speed of the drive wheel reaches 9m / s. The service life of the rubber wheel is detected by recording the start and end times of the test.

[0009] Preferably, the load-bearing mechanism includes an upper support, a sliding shaft, a tray, a counterweight, and a roller bracket. The bottom end of the upper support is connected to the top end of the base. The sliding shaft is slidably mounted on the upper support. The bottom end of the tray is connected to the top end of the sliding shaft. The counterweight is placed on the tray. The top end of the roller bracket is connected to the bottom end of the sliding shaft. The rubber wheel is rotatably mounted on the roller bracket. The operator places a suitable weight of counterweight on the tray, so that the total weight of the sliding shaft, tray, counterweight, and roller bracket reaches 240 kg, applying a constant 240 kg load to the rubber wheel, simulating the actual working state of the rubber wheel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff installs the rubber wheel to be tested onto the load mechanism, and then the load mechanism is weighed down to 240 kg to apply pressure to the rubber wheel to ensure that the rubber wheel reaches the working load. The drive mechanism is started to drive the rubber wheel to rotate, and the service life of the rubber wheel is tested. Attached Figure Description
