Description

Technical Field

[0001] This invention relates to the field of belt drive technology, and in particular to a belt drive detection device. Background Technology

[0002] Synchronous belt drive is a mechanical transmission method that transmits power through the meshing of belt teeth and pulley teeth. It is widely used in mechanical equipment and features high-precision transmission, high efficiency, compact structure, and simple maintenance.

[0003] Although synchronous belts have the advantage of high precision, tooth skipping may still occur in actual operation. This mainly manifests as the belt teeth slipping off the wheel teeth, leading to transmission failure or positional deviation.

[0004] Repeated tooth skipping over a long period of time will accelerate the wear of the timing belt and pulley, shorten their service life, cause periodic errors, and make the equipment unstable. If it is not detected in time, it may lead to unplanned downtime, and the repair cost is far higher than preventive maintenance.

[0005] Therefore, a series of comprehensive tests are necessary before belt drives can be applied in practice, which is of paramount importance. Preliminary testing effectively verifies the various performance indicators of the belt drive, ensuring its stable and reliable operation in actual use. This guarantees that its performance meets expected standards and ensures the safe and efficient operation of the entire transmission system.

[0006] Therefore, it is necessary to develop a new type of belt drive detection device to improve the aforementioned problems in related technologies. Summary of the Invention

[0007] The purpose of this invention is to provide a belt drive detection device that can detect tooth skipping in belt drives under different operating conditions.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] The belt drive detection device provided by the present invention includes: a support mechanism, a first mounting shaft, a second mounting shaft, a drive mechanism, a load mechanism, and a speed-changing mechanism; the first and second mounting shafts are rotatably disposed on the support mechanism for mounting pulleys and a drive belt; the drive mechanism and the load mechanism are respectively connected to the first mounting shaft and the second mounting shaft; the brake mechanism is connected to the load mechanism for braking the load mechanism; the speed-changing mechanism is disposed between the drive mechanism and the first mounting shaft, or between the load mechanism and the second mounting shaft.

[0010] Furthermore, the support mechanism includes a drive wheel mounting frame, a driven wheel mounting frame, and an adjusting base. The first mounting shaft is mounted on the drive wheel mounting frame, the second mounting shaft, the brake mechanism, and the load mechanism are mounted on the driven wheel mounting frame, and the driven wheel mounting frame is mounted on the adjusting base for adjusting the relative position between the drive wheel mounting frame and the driven wheel mounting frame.

[0011] Furthermore, the adjusting base includes a translation part and a screw. The translation part is provided with a plurality of waist holes, and the screw is disposed in the waist holes. It is used to drive the driven wheel mounting frame closer to or away from the driving wheel mounting frame by adjusting the position of the screw in the waist holes.

[0012] Furthermore, the adjusting base includes a rotating part and an operating lever connected to each other. The rotating part is rotatably disposed, and the driven wheel mounting bracket is disposed on the rotating part for driving the driven wheel mounting bracket to rotate by adjusting the operating lever.

[0013] Furthermore, the support mechanism includes a driven wheel mounting frame, and the second mounting shaft is disposed on the driven wheel mounting frame; the driven wheel mounting frame includes a first support plate, a second support plate, and a third support plate spaced apart, the speed change mechanism connects the second mounting shaft and the load mechanism, the second mounting shaft is located between the first support plate and the second support plate, the speed change mechanism is located between the second support plate and the third support plate, and the speed change mechanism and the load mechanism are respectively located on both sides of the third support plate.

[0014] Furthermore, the driven wheel mounting bracket includes a fourth support plate, a screw, and a tensioning wheel. The fourth support plate is disposed between the first support plate and the second support plate, and the tensioning wheel is disposed on the fourth support plate for tensioning the transmission belt. The fourth support plate has an arc-shaped waist hole, and the screw is disposed in the arc-shaped waist hole for adjusting the position of the tensioning wheel by adjusting the position of the screw in the arc-shaped waist hole to tension the transmission belt.

[0015] Furthermore, the braking mechanism includes a friction block with a flexible buffer layer. The friction block is movably configured to abut against the load mechanism after movement.

[0016] Furthermore, the support mechanism includes a base, a drive wheel mounting frame, a driven wheel mounting frame, and a top connecting rod. The drive wheel mounting frame and the driven wheel mounting frame are mounted on the base, and the top connecting rod is connected to the top of the drive wheel mounting frame and the driven wheel mounting frame, respectively.

[0017] Furthermore, the load mechanism includes a flywheel.

[0018] Compared with the prior art, the belt drive detection device provided by the present invention has the following advantages:

[0019] 1. In this invention, the first and second mounting shafts are rotatably mounted on a support mechanism. The first and second mounting shafts are connected by a drive mechanism and a load mechanism, respectively. After the pulley to be tested and the transmission belt are mounted on the first and second mounting shafts to form a transmission, the transmission speed, torque, power, acceleration, damping and other parameters can be adjusted by the speed change mechanism and the braking mechanism. This allows for observation of the belt drive's tooth skipping under different working conditions, which helps to ensure the reliability of the belt drive in actual operation.

[0020] 2. The present invention provides an adjustment base under the driven wheel mounting bracket. The driven wheel mounting bracket is moved by the adjustment base, and the relative position between the driving wheel mounting bracket and the driven wheel mounting bracket is adjusted. This causes the relative position between the second mounting shaft and the first mounting shaft to change. For example, the shaft spacing can be changed by the translation part or the rotation part, or the shaft can be misaligned, so as to obtain more transmission data under working conditions.

[0021] 3. The present invention forms a driven wheel mounting frame by arranging multiple support plates at intervals, and sets the load mechanism, speed change mechanism and second mounting shaft in different spaces formed by the support plates, which helps to increase the structural rigidity of the detection device and improve the transmission stability during detection.

[0022] 4. By setting a fourth support plate between the first support plate and the second support plate, and setting the tension force on the fourth support plate to tension the transmission belt, the present invention can obtain transmission data of belt drive under different tension forces.

[0023] 5. In this invention, the active wheel mounting frame and the driven wheel mounting frame are mounted on the base, and the tops of the two are connected by a top connecting rod, which further improves the structural rigidity of the detection device. Attached Figure Description
