worm gearbox:DGAB series torque from 400-48000N.m,
                             D sequence torque from 2000-180000 N.m

product design and style principles 
1.shell:
Dagong shall at least adopt the shell made of ductile iron, which can bear the extreme load in the earthquake region, 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 high-grade grease or lubricating oil which makes the worm  gear wear- resistant continuously, prolongs the service life of the product future enhances 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 altered to satisfy the requirements of the valve change.the altering screw seal is realized by the creation patent of the college of the engineering,which can guarantee different environmental seals ,such as higher temperature ,reduced temperature,deep sea,large and lower stress,continuous pressure and sturdy corrosion atmosphere.in the larger defense stage,the security cap can be utilized to attain double sealing.
4.Reduction gearbox:
the layout of the equipment strives to make the root stress of the two wheels equal,to meet the instantaneous torque attributes when the valve is opened and shut,and to increase the dress in interval of the pinion.the principal reduction gear makes use of the large module cylindrical equipment,and the planetary gear is employed to decrease the massive specification and high torque to obtain the essential enter torque.they can be utilized for handwheel operation,sprocket procedure and electric push gearbox.the gearbox layout have a particular area to meet the simultaneous deciphering time of the electrical set up when choosing different transmission ratios.
five.output flange:
The style regular of the output flange related with the valve shall be in accordance with ISO 5211.every specification supplies multiple flange options to satisfy the link specifications of the valve.
6.output shaft hole:
In accordance to ISO 5211 normal ,the output travel gap can be right custom-made in different measurements without added machining to meet the assembly needs of the valve stem.Provide numerous relationship approaches,these kinds of as multi crucial connection,diagonal sq. head,parallel square head,flat head,spline relationship,etc.
seven.enter shaft for handwheel procedure:
for the enter shaft of the gearbox operated by the hand wheel ,anti-corrosion security treatment shall be carried out or the stainless metal material shall be utilized directly .the lock gadget and 2-inch handwheel block driving areas can be specified .In accordance to the valve torque,the wheel specification can be picked,so as to fulfill the demands that the functioning power of the driving valve is not greater than that specified by the valve.
8.all goods are geared up with loc ept system:
It can be locked at any time when the web site wants to meet the requirements of the wor ept situations
Notice:we are committed to constant improvement of our goods and producing procedures.Samples are matter to alter with out prior recognize.
