Description

Technical Field

[0001] This utility model relates to the field of engineering machinery assembly technology, specifically to a track grease filling system. Background Technology

[0002] Tracks are a crucial component of the walking mechanism of excavators and other construction machinery, enabling them to move flexibly in complex terrain and confined spaces, enhancing their mobility. The tension of the tracks significantly impacts the walking mechanism of construction machinery; loose tracks are prone to slipping, while tight tracks result in slow movement; uneven track tension on both sides can cause the vehicle to veer off course. Therefore, ensuring proper track tension is a critical aspect of assembly quality.

[0003] Adjusting track tension on construction machinery involves adding grease to the tension spring. The increasing amount of grease compresses and pushes the idler wheel outward, gradually tightening the track. Traditional track tensioning assembly involves placing the assembled excavator or other construction machinery at the assembly station with the tracks on the ground. Grease is then added to the tension cylinder using a grease gun, causing the piston to extend and push the tension spring, moving the idler wheel to tighten the track. The amount of grease added relies on the assembler's experience or by measuring the distance between the upper edge of the track plate and the lower edge of the undercarriage to determine if the track is properly tensioned. However, due to the uneven weight distribution of the chassis, the track bears different loads on the left and right sides, leading to significant measurement errors in track tension measurement. This can easily result in tracks that are either too loose or too tight after tensioning, affecting the excavator's performance and lifespan. Utility Model Content
