worm gearbox:DGAB series torque from four hundred-48000N.m,
D collection torque from 2000-180000 N.m
product design and style principles
one.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
method data after multiple process evaluation,
and equipped with higher-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.
3.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be adjusted to meet the specifications of the valve swap.the adjusting screw seal is understood by the invention patent of the college of the technology,which can assure various environmental seals ,such as high temperature ,reduced temperature,deep sea,large and lower pressure,consistent pressure and strong corrosion surroundings.in the greater safety level,the protection cap can be employed to obtain double sealing.
four.Reduction gearbox:
the layout of the equipment strives to make the root stress of the two wheels equal,to meet up with the instantaneous torque attributes when the valve is opened and closed,and to lengthen the dress in interval of the pinion.the primary reduction equipment employs the huge module cylindrical gear,and the planetary gear is used to lessen the large specification and higher torque to accomplish the essential enter torque.they can be utilized for handwheel procedure,sprocket procedure and electrical drive gearbox.the gearbox style have a specific area to meet up with the simultaneous interpreting time of the electrical set up when deciding on diverse transmission ratios.
five.output flange:
The design and style standard of the output flange linked with the valve shall be in accordance with ISO 5211.each and every specification offers several flange alternatives to meet the connection specifications of the valve.
6.output shaft hole:
According to ISO 5211 common ,the output push hole can be right customized in various dimensions with out extra machining to meet the assembly specifications of the valve stem.Give a variety of connection techniques,this kind of as multi important connection,diagonal square head,parallel sq. head,flat head,spline link,and so forth.
7.enter shaft for handwheel procedure:
for the enter shaft of the gearbox operated by the hand wheel ,anti-corrosion security therapy shall be carried out or the stainless steel material shall be utilized right .the lock gadget and 2-inch handwheel block driving elements can be specified .According to the valve torque,the wheel specification can be chosen,so as to satisfy the demands that the working pressure of the driving valve is not increased than that specified by the valve.
8.all products are geared up with loc ept device:
It can be locked at any time when the internet site requirements to fulfill the needs of the wor ept problems
