worm gearbox:DGAB series torque from 400-48000N.m,
D sequence 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 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.
3.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to satisfy the demands of the valve swap.the altering screw seal is understood by the invention patent of the college of the technological innovation,which can ensure different environmental seals ,this kind of as high temperature ,lower temperature,deep sea,large and minimal strain,constant pressure and robust corrosion surroundings.in the greater defense stage,the security cap can be used to achieve double sealing.
4.Reduction gearbox:
the style of the equipment strives to make the root stress of the two wheels equivalent,to satisfy the instantaneous torque qualities when the valve is opened and closed,and to lengthen the wear period of the pinion.the primary reduction gear makes use of the large module cylindrical gear,and the planetary equipment is utilized to lessen the big specification and large torque to attain the required input torque.they can be employed for handwheel operation,sprocket procedure and electric drive gearbox.the gearbox style have a specific space to meet the simultaneous decoding time of the electrical set up when deciding on distinct transmission ratios.
five.output flange:
The layout normal of the output flange related with the valve shall be in accordance with ISO 5211.every single specification provides several flange alternatives to fulfill the connection needs of the valve.
six.output shaft gap:
In accordance to ISO 5211 common ,the output drive hole can be directly customized in distinct dimensions with no additional machining to fulfill the assembly demands of the valve stem.Provide a variety of link approaches,these kinds of as multi crucial relationship,diagonal sq. head,parallel sq. head,flat head,spline connection,and many others.
7.enter shaft for handwheel operation:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion protection therapy shall be carried out or the stainless metal content shall be employed straight .the lock gadget 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 up with the needs that the operating power of the driving valve is not better than that specified by the valve.
eight.all goods are outfitted with loc ept unit:
It can be locked at any time when the site wants to meet the demands of the wor ept situations
Observe:we are dedicated to constant advancement of our merchandise and producing procedures.Samples are topic to modify with no prior recognize.
