worm gearbox:DGAB collection torque from 400-48000N.m,
D collection torque from 2000-180000 N.m
merchandise style principles
Dagong shall at least adopt the shell made of ductile iron, which can bear the extreme load in the earthquake location, 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.
wear-resistant nodular cast iron worm gear is matched with alloy steel worm equipment, manufactured with improved
process data after multiple process evaluation,
and equipped with large-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.
three.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to satisfy the demands of the valve change.the altering screw seal is realized by the invention patent of the college of the technology,which can guarantee different environmental seals ,such as large temperature ,reduced temperature,deep sea,substantial and lower stress,continual stress and powerful corrosion environment.in the increased protection level,the safety cap can be utilised to obtain double sealing.
the design and style of the gear strives to make the root pressure of the two wheels equal,to meet the instantaneous torque traits when the valve is opened and closed,and to lengthen the use period of the pinion.the principal reduction gear uses the big module cylindrical gear,and the planetary gear is utilized to lessen the massive specification and large torque to achieve the essential enter torque.they can be utilized for handwheel procedure,sprocket operation and electric powered push gearbox.the gearbox layout have a specified area to meet the simultaneous deciphering time of the electrical installation when choosing various transmission ratios.
The design and style standard of the output flange linked with the valve shall be in accordance with ISO 5211.every specification gives several flange possibilities to meet the relationship demands of the valve.
6.output shaft gap:
According to ISO 5211 common ,the output drive hole can be straight custom-made in different dimensions with out added machining to fulfill the assembly needs of the valve stem.Provide numerous link strategies,this sort of as multi key link,diagonal square head,parallel sq. head,flat head,spline link,and many others.
7.input shaft for handwheel operation:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion security therapy shall be carried out or the stainless steel material shall be utilised right .the lock unit and 2-inch handwheel block driving areas can be specified .According to the valve torque,the wheel specification can be selected,so as to meet the requirements that the working power of the driving valve is not better than that specified by the valve.
8.all items are outfitted with loc ept device:
It can be locked at any time when the site wants to meet the needs of the wor ept situations
