Such bearings small size, high efficiency and durable, require high speed, minimal noise, non-power of plants can not manufacture. Its device-specific and strong, each with different design, using bearings are not the same, generally can not get ready cash, sometimes not easy to find (only frequent traveler customers only know to prepare for an emergency), it is recommended that the user is best done with a prepared one, avoid downtime to be parts, affecting production.
Seven, beer, beverage equipment, medical equipment selection bearings.
Eight, crushing, ceramic machinery, chemical machinery selection of bearings. Such equipment is poor work environment, more than a mist, moisture, dust, acid, etc., require a strong bearing seal, Shantou fat adequate and reasonable, it is best to add grease timely.

Wheel Bearing Maintenance

Before removing the wheels, wheel maintenance should do the preparatory work, the car parked and set up a bridge in order to ensure the maintenance of safe operations.
(1) Remove the hub shaft head decorative cover, dust cover;
(2) Remove the wheel nuts and tires, be careful not to bruise the tire bolt threads. If the disc brakes, the brake should be removed and then used pliers to remove the lock ring or locking pin.
(3) with a special tool to remove the hub;
(4) scrape ferris wheel bearing, journal and hub cavity of the old grease, cleaning wheel bearings and journal with detergent and dry with a cloth, and finally with a cloth to wipe the hub cavity.
(5) Check the wheel bearings and bearing races, found cracks, flaking and loose roller bearings and other phenomena, replace the bearings. If you find pitting on the bearing race, it should replace the bearings.
When cope with the situation
(6) Check the bearing bore and the journal, with the gap should not exceed 0.1Omm measuring journal, should be in the upper and lower parts of the vertical ground (where the maximum wear parts) measurements. If used with the gap exceeds the limit, replace the bearing, so back to normal with the gap. Is not allowed to play glitches, pitting the journal to narrow the gap.
(7) Upon completion of all parts meet the requirements, the inner flanged ball bearing grease after release hub.
(8) When grease the bearing cavity attention should be squeezed into the bearing grease until grease to date to emerge from the other side of the bearing. In the hub and shaft cranial cavity Apply a thin layer of grease to make it play a role in rust. Note the hub cavity grease Do not apply too much, otherwise it will affect the cooling and braking.
(9) the hub and the outer bearings mounted back on the journal, hand-axis head adjustment nut, and then use the shaft torque wrench required to tighten the adjusting nut. After tightening the nut, turning left and right wheels laps should see bearing installation; on the other hand, by rotating the bearing and the race proper fit. At this time spherical plain bearings tightness appropriate wheels to rotate freely and not feel the axial clearance.
(10) Finally, in order to install the locking plate, fixing nut, tires, dust cover and decorative cover and other parts.
(11) wheel bearings adjusted, with some mileage (about 1Okm), stop and check for swab touch wheel temperature, if fever, caused by bearing adjustment too tight, should be re-adjusted

appropriately relaxed bearing tightness.

Automated shiped loading machine

Loading machine is a large bulk mechanical dock for use bulk shipment. Usually ship loader boom belt by the transition belt conveyor, telescopic chute, tail car, running gear, masts, towers, pitch devices, rotary devices and other components, as shown in Figure 1. Bulk loading large port facilities, especially in some large, high-speed bulk distribution center in the energy, power, metallurgy, ports and other industries, stable, set effect, rolling development, plays an important role. ship loader bearing machines are generally continuous loading operations. Therefore, there must be a complete set of equipment to provide a continuous stream loading machine can make continuous shipment. Granary Wharf as feed grain, coal terminal in the quarry bucket wheel reclaimer continuous feeding feeder and so on.
Promote the development of global trade integration within the worldwide demand for bulk transport categories of goods from point of view, iron ore, coal, grain and other bulk cargo shipping volume rose showed rapid growth. Alongside this development is constantly updated ocean bulk transport ship. The attendant is able to dock and unload these large ships to build a super demand for bulk handling port boat equipment, increase the bulk cargo ship also pose new challenges for the design and manufacture of bulk handling equipment ship machines . According to the development trend of bulk automated, predictable, some developing trends shipment machines.
Since the loading and unloading of dry bulk cargo wharf with different characteristics, in addition to the type of ship is greater when coupled with the impact of bulk dust relatively poor operating environment, equipment and technology for the detection of a more demanding, so the current bulk loading boats low degree of automation systems, basically rely on manual field operations. The use of live human operator on the one hand due to the bulk terminal poor working conditions (high temperature, high dust, high noise, etc.) would endanger the health field staff, on the other hand due to poor working conditions and long cargo mobile crane bearing

, pole workers can lead to fatigue, resulting in an accident during shipment. Also due to manual loading, the operation will not standardized unscientific, such as to avoid a collision, the chute overhanging the cabin, causing dust emissions and loss of goods. Since the marina berth is a scarce resource, so the bulk terminal loading process become one of the bottleneck restricting the bulk of logistics, the urgent need to automate loading system, therefore, the future of one of the biggest trends for shipment machine automation will become increasingly high.

Wheel bearing installation, use common sense

Car wheel bearings are used in pairs over most single row tapered roller or ball bearings . With the development of technology, the car has been widely used car wheel units. Growing scope and use of the hub bearing unit, has now developed to the third generation: the first generation is a double row angular contact bearing components. The second generation of the outer raceway has a flange for fixing the bearing, the turntable bearing sleeve may simply be fixed with a nut on the axle.So that the vehicle maintenance becomes easy. The third generation wheel hub bearing units are used bearing units and anti-lock brake system fitted. Wheel hub unit is designed to have the inner flange and outer flange, the inner flange is bolted to the drive shaft, the entire bearing outer flange fit together.Worn or damaged wheel bearing or hub units will make your vehicle is involved in a high anachronistic and costly failure in traveling the road, or even cause damage to your safety. In the wheel bearings use and installation Please note the following:
1, in order to ensure maximum safety and can be *, regardless of the age of the vehicle is recommended that you should always check how long the wheel bearings - note bearing for wear early warning signals: includes any friction or noise when rotating wheel suspension combination abnormal deceleration when cornering.Rear-wheel drive vehicle is recommended for the vehicle to 38,000 km is to deal with the front wheel hub double row ball slewing bearing lubrication. When replacing the brake system, check the bearings and replace seals.
2. If you hear noise emitted wheel bearing parts, first of all, it is important to find the location of the noise occurs. There are many moving parts may produce noise, but also may be some non-rotating member and the rotating member contact occurs. If the confirmation is bearing noise, the bearing may be damaged and need replacing.
3, because the front wheel hub bearing failure leads to both sides working conditions are similar, so even if only one bearing bad, it is recommended to replace in pairs.
4, wheel bearing more sensitive, in any case need to adopt the right approach and the right tools. In storage and during installation, the thin wall bearings

 parts can not be damaged. Some bearings require greater pressure pushed, so they need special tools. Be sure to reference vehicle manufacturers instructions.
5, when installing the bearings should be clean and tidy environment, small particles from entering the bearing will shorten bearing life. When replacing the bearings to maintain a clean environment is very important. Do not allow the bearing with a hammer percussion, note bearing not fall to the ground (or similar misconduct). Before installing the shaft and the bearing housing should also check the condition of, even minor would lead to undesirable wear of mating, thereby causing early failure of the bearings.

Bearing applications in Gantry Crane

    Bridge, gantry crane and trolley carts wheels were powered by a 90 ° angle of the bearing housing assembly together into the wheel group, the overall adjustment tack welding station in the traveling frame, such a structure in the country has become a series of products, and widely used. It is characterized by the frame does not need to go on-line station processing, assembly more convenient. According to the case currently in use, taking into account the load-bearing parts crane wheels are in operation will be affected by the quality of rail and wheel installation itself manufacture and assembly deviation factor deviation, resulting deflect wheel slip, skew and other phenomena while the skew is important to be the one of the factors considered in the design. The main factor in the quality and the wheel itself to manufacturing variations, the deviation of the wheel assembly became gnawing rail mounted on the removal of track. So I plant using a 45 ° angle to assemble the wheel set ship loader bearing, mounted on a 35t and 10t container gantry crane gantry cranes General, and achieved good results.
  (1) The main features ① As the bearing welded to the station frame, supporting hole machining the bearing bore and the overall balance beam with a shape, by working to ensure the accuracy of assembly requirements, thereby greatly reducing the deviation of the wheel assembly group. ② repair, replacement parts wheel set is more convenient. (2) a few questions in the actual design and applications should be noted ① and balance beam supporting the mobile crane bearing

 bore hole while the design on the table frame, the processing, the installation process should be completed in time to ensure that its hole center line parallel, but also to ensure the balance of the wheel center plane of the support points.

Development of wheel bearings

   Traditional automotive agricultural bearings is composed of two tapered roller bearings or ball bearing combination, bearing installation, oiled, sealed and adjust clearance are carried out in the car on the production line. This structure makes it difficult in a car assembly plant, high cost, poor reliability, and maintenance car maintenance, but also the need for bearing cleaning, oiling and adjustment.
    Developed on the basis of the hub bearing unit is the standard angular contact ball bearings and tapered roller bearings on, it will be two sets of bearings as a whole, with good assembly performance can be omitted clearance adjustment, light weight, compact structure, load capacity large, sealed linear plain bearings grease can be loaded in advance, hub seals and omitted from the outside wheel maintenance, etc., has been widely used in cars, and in the truck also has a tendency to gradually expand the application.
