What is bearing in construction machinery?
With the development of the world economy, the rapid development of urban infrastructure and transportation infrastructure, the market has a corresponding increase in demand for construction machinery and equipment, and the consumption of bearings for construction machinery is also increasing day by day. Bearings with reliable quality and excellent performance can improve the efficiency of construction machinery. Reduce downtime, thereby creating greater value.
To understand which bearings are used in construction machinery, we must first understand what are there in construction machinery?
18 categories of products in the construction machinery industry, including excavating machinery, soil shoveling and transporting machinery, construction hoisting machinery, industrial vehicles, compaction machinery, piling machinery, concrete machinery, steel and prestressing machinery, decoration machinery, rock drilling machinery, pneumatics Tools, railway line machinery, military engineering machinery, elevators and escalators, special parts for engineering machinery, etc.
There are many types of construction machinery bearings
— Full complement cylindrical roller bearings (without outer ring)
— Cylindrical roller bearings: gearbox, roller eccentric shaft, travel reduction system, reducer
— Spherical roller bearings: roller eccentric shaft, reducer, cement mixer
— Tapered roller bearings: reducer, roller eccentric shaft, travel reduction system, rotating motor, sprocket transmission system, wheel end application,
— Deep groove ball bearings: rotating motors, reducers
— Angular contact ball bearings: reducer
— Needle bearing: gearbox, rotating motor, travel deceleration system
— Self-lubricating bearings: on various components such as the chassis traveling mechanism, body parts, and hydraulic components. Including bimetal boundary lubrication rolled bearings, metal-based self-lubricating bearings and metal plastic self-lubricating rolled bearings, etc.
Ordinary heavy industry construction machinery
①Excavating machinery such as single bucket excavators (also can be divided into crawler excavators and wheeled excavators), multi-bucket excavators (also can be divided into bucket wheel excavators and chain bucket excavators), multi-bucket trenching excavators Machine (also can be divided into bucket wheel trencher and bucket chain trencher), rolling excavator, milling excavator, tunnel boring machine (including shield machinery), etc.
②Shovel transportation machinery such as bulldozers (which can be further divided into tire-type bulldozers and crawler bulldozers), scrapers (which can be further divided into crawler self-propelled scrapers, tire self-propelled scrapers and drag scrapers), Loaders (also can be divided into tire loaders and crawler loaders, graders (also can be divided into self-propelled graders and towed graders), transport vehicles (also can be divided into single-axle transport vehicles and double-axle traction Transport vehicles), flatbed trucks and dump trucks.
③Lifting machinery such as tower cranes, self-propelled cranes, mast cranes, grab cranes, etc.
④Compaction machinery such as tire rollers, smooth wheel rollers, single foot rollers, vibratory rollers, compactors, tamping machines, etc.
⑤Piling machinery such as drilling machine, diesel pile driver, vibratory pile driver, breaker, etc.
⑥Reinforced concrete machinery such as concrete mixer, concrete mixing plant, concrete mixing building, concrete pump, concrete mixing truck, concrete spraying machine, concrete vibrator, steel bar processing machinery, etc.
⑦Road machinery such as leveling machine, ballast cleaning machine, etc.
⑧ Rock drilling machinery such as rock drilling rigs, pneumatic rock drills, electric rock drills, internal combustion rock drills and down-the-hole rock drills.
⑨Other construction machinery such as bridge erecting machine, pneumatic tools (pneumatic tools), etc.
