Description

Technical Field

[0001] This utility model relates to a lightweight, low-moment-of-inertia wire rope idler device. Background Technology

[0002] Crane wire rope idlers are a crucial auxiliary component that reduces direct friction between the wire rope and the crane's metal parts by supporting and guiding the rope, thereby extending the wire rope's lifespan and improving operational efficiency. The idler's design allows the wire rope to roll freely on its surface, which helps reduce jamming and protects the crane structure from impacts and damage. Furthermore, the ease of maintenance of the idlers means quick replacement and maintenance, reducing downtime and increasing crane utilization.

[0003] Crane wire rope idlers still present some problems in practical applications. For example, their low structural strength may lead to bending deformation under heavy pressure, causing misalignment of the idler and potential jamming during transmission. The large weight of the idlers results in a high moment of inertia, hindering rapid response to changes in wire rope movement, increasing friction between the wire rope and the idler, and accelerating wire rope wear. Furthermore, idlers with high moment of inertia experience greater vibration due to rotational imbalance, reducing the stability of the crane system. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the main purpose of this utility model is to overcome the shortcomings of the prior art and disclose a lightweight, low-moment-of-inertia wire rope idler device, including a shaft, a bearing and an idler body. The bearing is disposed on the shaft and the idler body is disposed on the bearing. The idler body includes a fixing part, a connecting part and a lifting part. The lifting part is connected to the fixing part through the connecting part. The cross-section of the idler body is I-shaped.

[0005] Furthermore, the cross-section of the lifting part is "V" shaped.

[0006] Furthermore, the fixing part, the connecting part, and the supporting part are an integral structure.

[0007] Furthermore, the bearing is connected to the fixing part and the bearing to the shaft by a retaining ring.

[0008] Furthermore, the shaft is a hollow shaft.

[0009] Furthermore, two bearings are provided.

[0010] Furthermore, a vulcanized rubber layer is fitted onto the surface of the supporting part.

[0011] Furthermore, the main body of the idler roller is made of magnesium-aluminum alloy.

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] This invention features a simple structure that is easy to process and maintain. By reducing the weight and rotational inertia of the overall structure, the idler body can respond more quickly to changes in the movement of the wire rope, starting or stopping more rapidly and reducing wear on the wire rope. The idler with low rotational inertia is easier to accelerate, thus requiring less energy to start and maintain its rotation. It also reduces vibration caused by rotational imbalance, helping to reduce the energy consumption of the entire system, reduce noise, and improve system stability. Attached Figure Description
