worm gearbox:DGAB series torque from four hundred-48000N.m,
                             D collection torque from 2000-180000 N.m

solution design and style principles 
one.shell:
Dagong shall at least adopt the shell made of ductile iron, which can bear the extreme load in the earthquake spot, with IP67 sealing grade, and the exposed parts shall be corrosion-resistant or the surface shall be protected with gray epoxy resin. Available in carbon steel, stainless steel, corrosion-resistant alloy and high and low temperature
 environment materials, including deep sea worm gear. 
2.Worm:
  wear-resistant nodular cast iron  worm gear is  matched with alloy steel worm gear, manufactured with improved
 process data after multiple process evaluation,
and equipped with substantial-grade grease or lubricating oil which makes the worm  gear wear- resistant continuously, prolongs the service life of the product future increases the switching torque characteristic and transmission efficiency applicable to the valve, and reduces the input torque. The large reduction ratio makes each pair of worm gears suitable for the self-locking capacity required by the valve to control the valve. Bronze worm gear and alloy steel worm gear are available.
3.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to meet the demands of the valve swap.the adjusting screw seal is understood by the creation patent of the college of the technology,which can promise numerous environmental seals ,this kind of as high temperature ,lower temperature,deep sea,higher and lower pressure,continuous stress and robust corrosion setting.in the increased defense degree,the defense cap can be utilized to accomplish double sealing.
4.Reduction gearbox:
the style of the equipment strives to make the root stress of the two wheels equal,to satisfy the instantaneous torque attributes when the valve is opened and closed,and to extend the dress in period of time of the pinion.the principal reduction equipment utilizes the huge module cylindrical equipment,and the planetary equipment is used to lessen the massive specification and substantial torque to achieve the required enter torque.they can be used for handwheel procedure,sprocket operation and electric powered drive gearbox.the gearbox layout have a particular area to meet the simultaneous decoding time of the electrical installation when picking different transmission ratios.
5.output flange:
The design and style common of the output flange linked with the valve shall be in accordance with ISO 5211.each and every specification provides multiple flange options to satisfy the connection demands of the valve.
6.output shaft gap:
In accordance to ISO 5211 normal ,the output push gap can be right customized in various sizes without further machining to meet the assembly needs of the valve stem.Provide numerous connection strategies,these kinds of as multi important link,diagonal square head,parallel sq. head,flat head,spline relationship,and so on.
7.input shaft for handwheel procedure:
for the enter shaft of the gearbox operated by the hand wheel ,anti-corrosion safety treatment shall be carried out or the stainless steel substance shall be used immediately .the lock device and 2-inch handwheel block driving components can be specified .According to the valve torque,the wheel specification can be chosen,so as to meet up with the requirements that the functioning power of the driving valve is not higher than that specified by the valve.
eight.all goods are equipped with loc ept system:
It can be locked at any time when the site requirements to meet the needs of the wor ept situations
Note:we are committed to continuous improvement of our merchandise and production procedures.Samples are topic to alter without having prior recognize.
