Description

Technical Field

[0001] This utility model relates to a track roller, specifically a double-track guided anti-detachment track roller structure, belonging to the technical field of track rollers. Background Technology

[0002] The dual-rail guided anti-slip track is an innovative track design. It features inner and outer guide rails; the inner rail fits snugly against the equipment chassis and other components, while the outer rail enhances overall structural stability. The unique meshing structure between the guide rails and the track effectively prevents the track from slipping off during operation, ensuring safe equipment operation. This track is widely used in agricultural and engineering machinery, significantly improving equipment reliability.

[0003] Track rollers are key components of tracked machinery. Installed under the tracks, they support the weight of the machine and reduce friction between the tracks and the ground. They roll in conjunction with the track movement and must be wear-resistant and impact-resistant to ensure smooth operation and extend the machine's lifespan.

[0004] Track rollers are typically fixed to the track frame with bolts. Under prolonged conditions of bumpy and vibrating operation, the bolts are prone to gradually loosening due to fatigue or insufficient preload, leading to overall displacement of the track roller. Therefore, a dual-rail guided anti-derailment track roller structure is proposed here. Utility Model Content
