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

item layout principles 
1.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. 
two.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 improves 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.
three.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to satisfy the requirements of the valve switch.the changing screw seal is recognized by the creation patent of the college of the engineering,which can assure a variety of environmental seals ,these kinds of as substantial temperature ,reduced temperature,deep sea,large and low strain,constant strain and strong corrosion environment.in the increased security degree,the security cap can be utilized to attain double sealing.
four.Reduction gearbox:
the style of the gear strives to make the root pressure of the two wheels equivalent,to meet the instantaneous torque characteristics when the valve is opened and shut,and to increase the dress in interval of the pinion.the main reduction equipment utilizes the massive module cylindrical equipment,and the planetary equipment is used to minimize the huge specification and high torque to attain the needed input torque.they can be utilised for handwheel operation,sprocket procedure and electrical travel gearbox.the gearbox layout have a particular space to satisfy the simultaneous deciphering time of the electrical installation when picking distinct transmission ratios.
five.output flange:
The design common of the output flange related with the valve shall be in accordance with ISO 5211.every single specification supplies several flange possibilities to meet up with the link needs of the valve.
six.output shaft hole:
In accordance to ISO 5211 regular ,the output generate gap can be right personalized in diverse sizes with no extra machining to meet the assembly specifications of the valve stem.Supply numerous link methods,this sort of as multi important link,diagonal square head,parallel square head,flat head,spline link,and so on.
7.enter shaft for handwheel operation:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion security remedy shall be carried out or the stainless steel substance shall be used straight .the lock gadget and 2-inch handwheel block driving parts can be specified .In accordance to the valve torque,the wheel specification can be picked,so as to meet up with the needs that the functioning force of the driving valve is not higher than that specified by the valve.
eight.all items are equipped with loc ept system:
It can be locked at any time when the web site demands to fulfill the requirements of the wor ept circumstances
