AGRICULTURAL FARMING WHEEL UNIT
More and more farmers are realizing the benefits of using tillers with independent cutters, faster speeds and better soil mixing capabilities, which directly saves more costs for the farm and provides better seedbeds for crop production.
As the core farming component, the agricultural hub unit must have a strong resistance to bias load impact and have perfect sealing performance, and in order to ensure work efficiency, it must reduce maintenance time and easy installation and replacement, and have lower energy consumption to reduce costs.
Perfect Sealing System
According to our long-term experience, about 78% of agricultural bearings and agricultural hub unit failures are due to the failure of the seal system, and the reasons for seal failure are various, so our recommendation is that the development of the seal system needs to fully understand the actual operating conditions, and then optimize through a systematic plan, rather than relying on a single seal. At the same time, the structure of the mating parts is optimized, only in this way can reliable product performance be guaranteed.
Agricultural hub unit adopts triple seal design, the external dust cover can effectively protect the bearing from the impact of stones and soil, and the internal unique six-lip oil seal can effectively prevent rain and mud from entering, and keep the internal oil pure. One side connected with the rake is equipped with a double static seal to prevent the entry of external dirt.
AGRICULTURAL MACHINERY BEARING
Agricultural machinery bearings are the most symbolic rolling bearings with a wide range of applications. It works very fast, can even reach high speeds, is very durable, and does not require frequent maintenance. The bearing has the advantages of low friction resistance, high limit speed ratio, simple structure, low production cost and high production precision. The types and methods of products are different, suitable for all kinds of instruments, low noise motors, automobiles, motorcycles, chemical machinery and so on. In the mechanical field, it is the most commonly used kind of bearing. It can not only bear axial load, but also bear a certain radial load.
Agricultural Machinery Bearing Characteristics
The sealing performance is superior, and the service life of various agricultural machinery is extended to the greatest extent.
Customized solutions that can easily cope with demanding application environments.
Environmentally friendly, maintenance-free solutions that reduce labor, lubrication and machine acquisition costs.
Agricultural Machinery Bearing Maintenance
In order to better maintain the original performance of agricultural machinery bearings, maintenance and maintenance must be carried out to avoid safety accidents, ensure the effectiveness of operation, improve productivity, and rationalize it. Maintenance practice is very good in the actual operation of industry equipment standards. The main content is to check the actual operating specifications of the work, repair or remove lubricating oil, and disassemble in time. In the daily maintenance, there are new products of agricultural machinery bearing rotation, vibration, temperature, lubrication and so on.
INSERT BEARING
INSERT BEARING is easier to use than the general deep groove ball bearing, which is characterized by simple loading and unloading and can be aligning. The standard tolerance of the INSERT BEARING is: inside plus outside minus, and the inner diameter is plus tolerance to ensure the lightness when matching with the shaft; Each set of INSERT BEARING is not used alone, and it must be matched to the internal integral installation of the bearing seat. INSERT BEARING can be divided into three categories according to the locking method with the shaft:
Insert Bearing With Top Wire
Its code name is :UC200 series (light series), UC300 series (heavy series), and deformation products UB(SB)200 series, if the use of environmental load is small, generally choose UC200 series, vice versa.
Insert Bearing With Taper
Its code-name is :UK200 series, UK300 series. This kind of INSERT BEARING inner diameter is 1:12 ratio taper hole, when used with the tight sleeve, the characteristics of this kind of INSERT BEARING is: can withstand greater load than the INSERT BEARING with top wire.
Insert Bearing With Eccentric Sleeve
Its code-names are :UEL200 series, UEL300 Series, SA200 series. The main feature of this kind of INSERT BEARING is that the upper end of the bearing has a certain eccentricity, and the eccentric sleeve with the same eccentricity is matched with it. This kind of bearing can also be said to be a special bearing, because it is mainly used in agricultural machinery (harvester, straw returning machine, thresher, etc.), such external spherical ball bearings are mainly used in the structure of beating more violent, eccentric structure can effectively reduce the violent beating.
Seal
Insert bearing than other ordinary bearings have another feature is double seal, because the general external spherical ball bearings use environmental conditions are harsh, especially agricultural machinery bearings more so, and double seal to ensure that dust is not easy to enter its channel inside, the company has developed a three-lip sealed external spherical bearings to greatly strengthen the dust resistance, extend the service life of the bearing.
HOUSING BEARING
Outer spherical bearing with seat is a bearing unit which combines outer spherical bearing with bearing seat. Most of the outer spherical bearings are made of spherical outer diameter, and are installed together with the bearing seat with a spherical inner hole, and the structure is diverse, and the versatility and interchangeability are good.
Bearing seat is generally cast forming and stamping forming two kinds. Often supporting the casting bearing seat are vertical seat (P), narrow vertical seat (PA), high center vertical seat (PH), square seat (F), convex square seat (FS), convex circular seat (FC), diamond seat (FL), ring seat (C), slide block seat (T) ), suspension seat (HA), adjustable diamond seat (FA), suspension bearing seat (FB); Often supporting the stamping bearing seat are round stamping seat (PF), diamond stamping seat (PFL), triangle stamping seat (PFT), vertical stamping seat (PP) and so on.
DOUBLE ROW ANGULAR CONTACT BALL BEARING
Double row angular contact ball bearings can withstand radial loads and axial loads acting in both directions, it can limit the shaft or housing two-way axial displacement, the contact Angle is 30 degrees. High rigidity bearing configurations are available and can withstand overturning moments.
Apply
Double row angular contact ball bearings have better rigidity and can withstand overturning moment. Bearings are non-separated. Especially suitable for applications with high rigidity requirements. It is widely used in the front wheel hub of the car (some models also use double row tapered roller bearings of the same size).
Peculiarity
The inclinability between the inner and outer rings of double-row angular contact ball bearings is limited, and the allowable inclination Angle depends on the internal clearance of the bearing, the bearing size, the internal design and the force and moment acting on the bearing, and the maximum allowable inclination Angle should ensure that there is no excessive additional stress in the bearing.
If the inclination Angle between the inner and outer rings of the bearing exists, the life of the bearing will be affected, and the running accuracy of the bearing will be reduced, and the running noise will be increased. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, attention should be paid to the fact that although the bearings can withstand two-way axial loads, if there is a ball loading gap on one side, care should be taken not to let the main axial load pass through the groove side with a gap. When the bearing is used, attention should be paid to making the raceway without the ball filling gap bear the main load.
In addition, double row angular contact ball bearings also have good rigidity and can withstand overturning moment. Bearings are non-separated. Especially suitable for applications with high rigidity requirements. It is widely used in front wheel hubs of cars.
NO-TILL SEEDER BEARING
Agricultural machinery is exposed to dust, debris, mud, rain and other environments for a long time, lasting vibration and crop straw impact throughout the working season; Contamination intrusion or loss of grease due to seal failure often leads to premature failure of agricultural bearings and equipment failure. Such as peeling machine such parts, installation space is very small, the working environment is particularly harsh, which needs to reduce the need for maintenance and lubrication, in the harvest season, agricultural machinery failure, unplanned stop opportunity to cause huge production losses, no-tillage machine seed bearing, sealed, maintenance-free, can effectively reduce maintenance costs, improve machine performance.
Bearing Composition
The bearing consists of an outer ring, an inner ring, two rows of steel balls and two groups of retainers, which can withstand radial loads and axial loads acting in both directions, limiting the two-way axial displacement of the shaft or housing.
Bearing Seal
The sealing ring structure of the agricultural machinery bearing is very special, it is a kind of rolling steel skeleton three-layer rubber lip with large interference contact sealing ring, which can not only keep the bearing external soil and sand water entering but also prevent the loss of grease inside the bearing, and the sealing material has good sealing performance.
Grease
Bearings are filled with high quality grease with a consistency that can be used at temperatures of -30 and +150 degrees. Lifetime lubrication and maintenance free.
Cage
All nylon retractor, its light weight, making the bearing flexibility is good, relative to the metal cage, it can effectively extend the service life of the bearing, less metal cage and steel ball friction, relatively extend the life of the bearing.
