worm gearbox:DGAB series torque from four hundred-48000N.m,
D series torque from 2000-180000 N.m
product style principles
one.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 large-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.
three.mechanical limit and seal:
The travel limit screw with an angle of -90°( ±5°)can be adjusted to meet the demands of the valve change.the modifying screw seal is understood by the invention patent of the university of the technologies,which can promise a variety of environmental seals ,these kinds of as higher temperature ,reduced temperature,deep sea,large and low pressure,continual pressure and robust corrosion environment.in the larger protection amount,the security cap can be employed to attain double sealing.
four.Reduction gearbox:
the design and style of the gear strives to make the root stress of the two wheels equivalent,to meet the instantaneous torque attributes when the valve is opened and shut,and to lengthen the use period of time of the pinion.the major reduction gear uses the massive module cylindrical equipment,and the planetary equipment is employed to lessen the big specification and substantial torque to obtain the necessary enter torque.they can be utilised for handwheel procedure,sprocket procedure and electric powered push gearbox.the gearbox layout have a specific place to satisfy the simultaneous interpreting time of the electrical set up when selecting various transmission ratios.
5.output flange:
The design regular of the output flange connected with the valve shall be in accordance with ISO 5211.every specification offers a number of flange possibilities to meet the link specifications of the valve.
six.output shaft gap:
In accordance to ISO 5211 regular ,the output generate gap can be directly custom-made in various dimensions with out added machining to satisfy the assembly requirements of the valve stem.Offer a variety of relationship techniques,this kind of as multi key link,diagonal sq. head,parallel sq. head,flat head,spline relationship,and so on.
7.input shaft for handwheel procedure:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion security treatment shall be carried out or the stainless metal material shall be used directly .the lock device and 2-inch handwheel block driving areas can be specified .According to the valve torque,the wheel specification can be chosen,so as to meet the requirements that the operating drive of the driving valve is not greater than that specified by the valve.
eight.all goods are outfitted with loc ept gadget:
It can be locked at any time when the internet site wants to fulfill the demands of the wor ept problems
