In the huge mechanical structure of excavators and bulldozers, track shoe bolts and nuts play a vital role as important components for connection and fixing. As a GFM excavator and bulldozer parts manufacturer, we are committed to providing customers with high-quality track shoe bolts and nuts products to ensure the efficient operation and safety performance of the equipment.
What are track shoe bolts and nuts?
Screws, commonly known as bolts, have external threads and are usually used to connect and fix mechanical parts. Nuts are usually hexagonal in shape and have internal threads in the inner hole, which are used to cooperate with bolts to tightly fix related parts together. In the chain plate structure of excavators and bulldozers, the track shoe bolts and nuts combination plays a key role in connection and fixing. These track shoe bolts and nuts not only bear the weight of the equipment, but also need to withstand complex working environments, including high temperature, vibration, impact and sediment erosion.
Function and principle
Function
- Fixed chain rail system: ensure stable connection between track shoe and chain rail section to prevent loosening or breakage.
- Transmit power: through cooperation with the chain rail, the power output of the engine is transmitted to the ground to ensure the smoothness and accuracy of equipment movement.
- Impact and wear resistance: Provide strong impact and wear resistance in high-load working environments, extending the service life of the chain rail system.
Working principle
The track shoe bolts are tightened with the nuts through their threads to form a strong clamping force, firmly fixing the track shoe and the chain rail section. High-strength materials and precision manufacturing processes ensure that the bolts and nuts will not loosen or deform under high pressure and high friction environments.
Production process
The production process oftrack shoe bolts and nuts mainly includes the following steps:
- Raw material selection: Select high-strength alloy steel, such as 40Cr and 42CrMo, to ensure the strength and toughness of the product.
- Steel stamping: The steel is processed into the preliminary shape of the bolt and nut through a stamping process.
- Tapping: Process threads on the bolt shank and the inner hole of the nut.
- Heat treatment: Heat treatment of bolts and nuts to improve their hardness and strength.
- Surface treatment: Electroplating or spraying of bolts and nuts to enhance their corrosion resistance and aesthetics.
- Quality inspection: After hardness test, tensile strength test and fatigue test, ensure that each screw and nut meets international standards.
How to judge quality
The quality of grouser track bolts and nuts can be judged from the following aspects:
- Appearance inspection: The surface of high-quality bolts and nuts should be smooth and flat, without defects such as burrs, cracks, pits, etc.
- Thread regularity: The thread should be clear and uniform, without deformation, missing teeth, random buckles and other problems.
- Material identification: Through magnet detection and hardness test and other methods, judge whether the material of the bolts and nuts meets the requirements.
- Mechanical properties: Through tensile strength and torque test and other methods, check whether the mechanical properties of the bolts and nuts meet the standards.
