We – EPG Team the greatest worm gearbox, couplings and gears factory in China with 5 distinct branches. For far more information: Mobile/whatsapp/telegram/Kakao us at: 0086~13083988828 13858117778083988828 /
worm gearbox:DGAB series torque from 400-48000N.m,
D sequence torque from 2000-180000 N.m
solution layout principles
1.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 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.
3.mechanical limit and seal:
The travel limit screw with an angle of -90°( ±5°)can be altered to meet the specifications of the valve change.the altering screw seal is realized by the invention patent of the college of the technology,which can guarantee numerous environmental seals ,this kind of as large temperature ,lower temperature,deep sea,higher and lower stress,continual strain and robust corrosion setting.in the greater security level,the safety cap can be utilized to accomplish double sealing.
4.Reduction gearbox:
the design of the equipment strives to make the root anxiety of the two wheels equal,to fulfill the instantaneous torque characteristics when the valve is opened and shut,and to extend the dress in interval of the pinion.the main reduction equipment makes use of the massive module cylindrical equipment,and the planetary equipment is utilized to reduce the massive specification and large torque to obtain the required input torque.they can be utilized for handwheel procedure,sprocket operation and electric generate gearbox.the gearbox layout have a certain area to fulfill the simultaneous interpreting time of the electrical set up when choosing distinct transmission ratios.
5.output flange:
The layout normal of the output flange linked with the valve shall be in accordance with ISO 5211.every single specification provides multiple flange alternatives to satisfy the link needs of the valve.
6.output shaft hole:
In accordance to ISO 5211 normal ,the output travel gap can be right tailored in diverse dimensions without added machining to fulfill the assembly requirements of the valve stem.Offer different link techniques,this sort of as multi important connection,diagonal square head,parallel sq. head,flat head,spline connection,and so on.
seven.enter shaft for handwheel procedure:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion defense therapy shall be carried out or the stainless steel materials shall be utilised right .the lock gadget 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 requirements that the functioning power of the driving valve is not better than that specified by the valve.
eight.all goods are geared up with loc ept system:
It can be locked at any time when the site demands to meet the specifications of the wor ept situations
