Hercules - Truck Crane
We can often see it running heavyweight goods for people on the street. It seems like the Sun Wukong is the same as the Sun Wukong. The name of this Hercules is called. We come under simple science. It is a kind of equipment that can lift, rotate and lift the goods by hydraulic lifting and telescopic system. Usually it can be seen to be assembled on the truck. The total components are: truck chassis, cargo box, power take-off, crane. Therefore, we also take it as usual: Hang with the car. However, there are many local customs will be called car cranes, self-cranes and so on. In short, it is a car that can be used to hang goods. Many people will certainly want to know how the truck crane works. After all, it can replace the power that people can't give. How does it work? Mainly through the hydraulic transmission principle to achieve a variety of mechanical actions. A lot of commonly used is the power of the car, through the power taker to drive the hydraulic oil pump, connect the hydraulic valve to achieve work. Of course, if there is no car power, we can only provide the power source through the pump motor unit. The pump motor unit is driven by the 380V voltage to drive the motor in the field, in docks, ships, workshops and other vehicles without the power of the vehicle . The troublesome use of an oil pump motor unit is that it requires the generator to generate electricity before it can work, and the motor is used to drive the pump. At present, the truck-mounted cranes in our country are mainly in the form of rack rotation and slewing ring. The two main differences between them are that rack rotation is the crane's cylinder driving the rack movement to rotate the column. We all know that the rack is a straight line, so after it has been rotated to a certain position, it cannot move forward. Therefore, the rack rotation has a range. According to the truck crane described above, do you know a lot about the basics, at least not wanting to be intimidated when you want to operate the truck crane in the future?
Brass cage spherical Roller Bearing , which have two rows of barrel shaped symmetrical rollers, and held in a brass cage without fixed middle block. a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis .Therefore, spherical roller bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, The center point of the sphere in the outer ring raceway is at the roller bearing axis. modified line contact between rollers and internal & external ring to achieve maximum loading capacity. mainly bear radial load.
FEATURE:
brass cages Spherical Roller Bearing have a much higher resistance to adhesive bonding, for this reason, even in harsh conditions, when lubrication is insufficient, they enable bearings to attain the design rating life. The design of Spherical Roller Bearing allows the roller rows in roller bearing to run at different speeds, thereby enabling the bearing to absorb high levels of linear deviation. Spherical roller bearings have high radial load capacity, which is especially suitable for work under the heavy load, high shock or vibration load and misaligned loads, but can't afford to pure axial load.
TYPES:
Due to customers` requirements, XKTE can offer different structures of spherical roller bearing, such as steel sheet metal frame structure(C type), brass solid cage structure(CA type/M type)
When a rolling bearing equipped with a steel cage works in condition of poor lubrication, hard contaminants might appear as a result of the adhesive wear at the cage-rolling element contact. Since sliding cannot be eliminated in the contacts between the cage and other bearing parts, the cage itself is the first component to be affected when lubrication becomes inadequate. Select a cage material able to ensure, against hardened steel and in boundary lubrication regime, reduced values for the friction coefficient as well as a very high resistance to welding. In this regard, brass proved to be the best choice.
Some spherical roller bearing variants may include perforated outer ring and oil groove features in their design to facilitate easier lubrication and further extending their longevity. with the suffix W33 or H.
APPLICATION:
Spherical roller bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk Conveyor Pulley. In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
We set up a one-stop production line, committed to producing and researching supporting roller bearings and Conveyor Bearing over the years. There are many long-term fixed Senior conveyor machinery partner in domestic and abroad market. Welcome conveying machinery manufacturers` contact from all over the world
