Liugong 72A0008 Left Sprocket: Precise meshing, heavy-load resistance, and stable traction for track travel.

For tracked equipment such as excavators and bulldozers, the left-hand sprocket is... “ The final link in power transmission — It meshes precisely with the tooth surfaces of the drive sprocket, converting the engine’s power into the traction force that drives the track. If the tooth surfaces of the sprocket become worn and blunted, ... “ Slipping due to skipped teeth ” When climbing steep slopes under heavy load, the machine suddenly loses power. If the meshing clearance of the non-OEM sprockets is too large, it can cause track deviation and impact-induced fracture of the tooth surfaces. Replacing them once not only incurs high parts costs but also delays the entire shift’s work schedule. LiuGong. 72A0008 The left-side gear body, custom-made by the manufacturer. “ Walking engagement core ” Ensuring stable track engagement, sufficient traction, and slow wear, making it ideal for heavy-duty operating conditions. “ Walking power anchor ”。

Factory-precision fit: No misalignment, no loss of power.

The meshing accuracy of the left-hand gear directly determines the efficiency of power transmission, LiuGong. 72A0008 R&D based on 3D data of LiuGong’s complete machine walking system: Key parameters such as tooth top height, tooth root thickness, and pitch are precisely matched with the drive wheel and track links, and the meshing clearance is controlled within... 0.2-0.5mm Between them, avoid non-original gear bodies. “ Tooth pitch deviation causes jamming. “” The tooth tips are too thick, damaging the track. ” The issue; the mounting hole positions, locating pin holes, and drive wheel hub fit perfectly with no gaps, with an error of less than... 0.1mm After being secured with the original factory’s high-strength bolts, the radial runout is less than... 0.03mm , eliminate bumpy operations “ Tooth body wobble causes meshing misalignment. ” Regarding the steering force characteristics of the left-side walking system, the tooth body installation angle has been specially calibrated to ensure smoother meshing during steering and reduce lateral wear on the tracks.

Wear-resistant and fracture-resistant core: Even under heavy impact! “ Can handle it. ”

Addressing the pain point of tooth-body wear in heavy-load scenarios such as mining and infrastructure projects, 72A0008 Adopt “ Reinforced material + Precision craftsmanship ” Double upgrade: The tooth body adopts 42CrMo Made from alloy steel via integral forging, replacing traditional castings, it features no internal defects such as porosity or gas holes, and boasts a tensile strength of... 1080MPa Even when the equipment experiences instantaneous impact forces during heavy-load starts, tooth root fractures will not occur; the tooth surfaces have been... “ Dual-frequency quenching + Low-temperature tempering ” Processing, surface hardness reaches HRC60-63 The core maintains excellent toughness, offering both wear resistance and impact resistance, with reduced tooth surface wear compared to conventional gear teeth. 60% On gravel roads, the service life can reach 1.2 Over 10,000 hours; the tooth root features an arc-transition design to eliminate stress concentration and prevent... “ Tooth root cracking ” This common malfunction.

Precision engagement design: reduces vibration for the track, ensuring smoother and more stable walking.

Tracked walking “ Stability and savings ” Hidden within the meshing details of the tooth bodies: 72A0008 The tooth surface adopts “ Involute tooth profile ” Design, with increased engagement contact surface for the track chain. 30% The load is distributed more evenly, reducing wear on the track link holes caused by excessive local stress. The tooth surfaces have undergone precision grinding, resulting in a surface roughness that... Ra ≤ 0.8 μm Frictional resistance is reduced during engagement. 25% , reduce “ Abrasive wear on tooth surfaces ” At the same time, it reduces walking noise and improves the working environment on construction sites. The engagement phase between the left-side sprocket and the right-side sprocket is precisely synchronized, ensuring even force distribution on both sides of the track and preventing excessive wear on any single side, thereby extending the overall service life of the track.

Built to withstand all conditions: No problem navigating harsh terrains. “ Chain drop ”

From the infrastructure construction site in muddy swamps to the rock-exposed mine working faces, 72A0008 All can perform their duties reliably: The tooth surface adopts “ Zinc-aluminum coating + Pore-sealing treatment ” Salt spray test 720 It is rust-free for hours and can resist corrosion in paddy fields and coastal construction sites. The gear body material contains low-temperature-resistant alloy elements. -35℃ In harsh cold environments, it exhibits no brittle cracking and can still engage and deliver normal power after a cold start in Northeast China’s winter. For high-dust environments, dust-guiding grooves are incorporated at the tooth roots to prevent dust accumulation that could otherwise lead to... “ Engagement jamming ” Reduce the frequency of manual cleaning and ensure track performance under all kinds of extreme operating conditions. “ Smooth engagement, no tooth skipping. ”。

Provincial-level device protection value: One-time selection, multiple benefits.

72A0008 of the “ Provincial-level attribute ” Throughout the equipment’s entire lifecycle: wear-resistant tooth surfaces extend their own service life to that of conventional tooth bodies. 1.8 Twice, replacing annually according to standard tooth profile. 2 With this calculation, annual savings on parts costs can exceed... 4000 Yuan: Precise meshing reduces wear on track links and drive sprockets, thereby extending the lifespan of the tracks. 30% A set of tracks can save over ten thousand yuan in replacement costs; it also helps avoid failures caused by gear body malfunctions. “ Skipping teeth, deviation, shutdown ” by the average daily output value of equipment 8000 In theory, a single successful replacement can be reversed. 1-2 Losses due to work stoppages caused by weather are particularly suitable for projects with tight schedules.

Rigorous quality control ensures peace of mind: Factory-backed guarantee, seamless engagement with zero risk.

LiuGong vs. 72A0008 Left tooth body execution “ Walking system level ” End-to-end quality control: Every tooth body must pass through. “ Gear Tooth Accuracy Inspection 10 Tonne Impact Strength Test “20 Ten-thousand-cycle meshing fatigue test ” , verify meshing accuracy and durability; proceed with “ High-frequency vibration testing ” Simulates stability under the bumpy conditions of a construction site. During the finished-product stage, assembly tests are conducted with the drive wheels and tracks to ensure smooth engagement without any jamming or sticking. Each gear component is equipped with a unique, factory-originated traceability code; scanning this code allows you to query the production batch and inspection data, completely eliminating counterfeit products. “ Tooth profile deviation, prone to fracture ” The risk of.
