Description

Technical Field

[0001] This utility model relates to the field of lubrication and wear resistance technology for engineering machinery transmission systems, and more specifically to a high wear-resistant excavator track plate. Background Technology

[0002] Excavators are heavy machinery widely used in engineering construction, mining, farmland irrigation and other fields. They are mainly used for digging, transporting and breaking soil or rocks. When moving, they usually move by means of tracks composed of multiple track plates. Over time, the tracks and external gears will wear down.

[0003] The shortcomings of existing technology: In existing excavator equipment, the tracks are driven by two external gears on two drive shafts. However, during the meshing transmission between the tracks and the external gears, friction occurs between them. Due to the lack of a lubrication structure, lubricating oil cannot be dripped onto the tracks and external gears, resulting in wear between them. This increases the meshing clearance between the track pads and the drive wheels, further leading to track derailment, tooth slippage, or breakage. This increases the maintenance and replacement costs of the equipment, reduces its practicality, and is not conducive to actual application and operation. Utility Model Content

[0050] Please see Figure 1-5 This utility model embodiment provides a high wear-resistant excavator track plate, comprising:

[0051] The track drive assembly 1 consists of two rotating shafts 11, two external gears 12 and a track 13, and is used as the mounting carrier for the U-shaped support plate 2.

[0052] The U-shaped receiving plate 2 is rotatably fitted between two rotating shafts 11 and is fixedly connected to the oil storage component 3 and the self-lubricating component 4 through the magnetic suction component 5, serving as the mounting carrier for the magnetic suction component 5.

[0053] The self-lubricating component 4 is used to lubricate the track drive assembly 1.

[0054] The self-lubricating component 4 includes:

[0055] Activity box 41;
