Use of loader bearings
The following are the core application scenarios and key technical points of loader bearings, which are explained in combination with the structural characteristics of the equipment and maintenance standards:
I. Types and Functions of Bearings in Key Parts
1. Youdaoplaceholder0 articulated system universal joint bearing
The core function of is : connecting the front and rear frames, automatically compensating for manufacturing deviations (allowing ±2° deviation), and buffering the impact load on the road surface
Youdaoplaceholder0 special design :
Alloy material enhances compressive strength (load-bearing capacity ≥8 tons)
The dust-proof efficiency of the double lip oil seal structure is over 95%, and the grease cavity is designed with independent sealing
Youdaoplaceholder0 Maintenance points : Grease once a week (lithium-based grease), with the filling volume being 1/3 of the cavity to prevent heating
2. Youdaoplaceholder0 hub tapered roller bearing
Youdaoplaceholder0 model example : 30218 (Series 3)
Youdaoplaceholder0 operating condition requirements :
Withstand the jolting vibration of the tracks and radial impact loads
Surface carburizing treatment (hardness 60-62 HRC) enhances wear resistance
Youdaoplaceholder0 Seal upgrade : Dual protection of rubber labyrinth seal and metal dust cover (suffix 2RS/HD)
3. Planetary gears of transmission
Youdaoplaceholder0 Bearing type : needle roller bearing (full complement type)
Youdaoplaceholder0 Technical advantages :
High load density (radial load capacity increased by 40%), suitable for compact Spaces
Special convex needle roller busbars reduce contact stress and resist fretting wear
Youdaoplaceholder0 Failure prevention : Change gear oil (viscosity ISO VG 220) every 500 hours
Ii. Special Working Condition Adaptation Plan
Youdaoplaceholder0 heavy-load impact protection
The mining operation equipment adopts custom-made tapered roller bearings with enlarged rollers (diameter +10%)
Youdaoplaceholder0 High-temperature lubrication management
The bearings of the hydraulic system use synthetic high-temperature grease (with a temperature resistance of ≥150℃) to prevent oil film rupture
Youdaoplaceholder0 installation accuracy control
The installation of hinged pin bearings should ensure that the frame closure clearance is 2-3mm to prevent the main pin from getting stuck
Iii. Direction of Technological Evolution
Youdaoplaceholder0 Intelligent diagnosis : Integrated vibration sensor predicts raceway spalling (such as early failure of hub bearings)
Youdaoplaceholder0 Integrated design : Flanged hub unit integrates sealing and sensing modules, reducing maintenance costs by 40% 9
Youdaoplaceholder0 Lightweight : Ceramic hybrid bearings reduce weight by 15%, improving fuel efficiency
