worm gearbox:DGAB sequence torque from four hundred-48000N.m,
D series torque from 2000-180000 N.m
merchandise design principles
1.shell:
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.
two.Worm:
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 substantial-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 limit and seal:
The travel limit screw with an angle of -90°( ±5°)can be adjusted to satisfy the requirements of the valve swap.the changing screw seal is recognized by the invention patent of the university of the technological innovation,which can ensure various environmental seals ,such as substantial temperature ,low temperature,deep sea,substantial and lower strain,consistent stress and sturdy corrosion setting.in the greater security degree,the security cap can be utilised to achieve double sealing.
four.Reduction gearbox:
the design and style of the equipment strives to make the root pressure of the two wheels equal,to fulfill the instantaneous torque attributes when the valve is opened and closed,and to prolong the dress in interval of the pinion.the major reduction equipment makes use of the large module cylindrical gear,and the planetary gear is utilised to lessen the massive specification and substantial torque to attain the essential enter torque.they can be employed for handwheel procedure,sprocket procedure and electric powered generate gearbox.the gearbox layout have a certain place to meet the simultaneous decoding time of the electrical installation when choosing various transmission ratios.
5.output flange:
The layout common of the output flange linked with the valve shall be in accordance with ISO 5211.each specification gives several flange options to meet the link demands of the valve.
six.output shaft gap:
In accordance to ISO 5211 standard ,the output travel hole can be straight customized in different measurements without extra machining to satisfy the assembly specifications of the valve stem.Supply a variety of link methods,this kind of as multi essential connection,diagonal square head,parallel sq. head,flat head,spline relationship,and so on.
seven.enter shaft for handwheel procedure:
for the enter shaft of the gearbox operated by the hand wheel ,anti-corrosion safety treatment method shall be carried out or the stainless metal materials shall be utilised straight .the lock unit and 2-inch handwheel block driving parts can be specified .According to the valve torque,the wheel specification can be picked,so as to meet the needs that the working force of the driving valve is not greater than that specified by the valve.
eight.all products are geared up with loc ept unit:
It can be locked at any time when the web site demands to fulfill the specifications of the wor ept conditions
