worm gearbox:DGAB series torque from four hundred-48000N.m,
D series torque from 2000-180000 N.m
merchandise style principles
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.
wear-resistant nodular cast iron worm gear is matched with alloy steel worm gear, manufactured with improved
process 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 limit and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to satisfy the requirements of the valve change.the changing screw seal is recognized by the invention patent of the university of the engineering,which can promise various environmental seals ,this sort of as large temperature ,lower temperature,deep sea,higher and low force,continual force and sturdy corrosion environment.in the increased security degree,the security cap can be utilised to achieve double sealing.
the design and style of the equipment strives to make the root tension of the two wheels equal,to meet the instantaneous torque qualities when the valve is opened and closed,and to prolong the put on interval of the pinion.the main reduction gear utilizes the massive module cylindrical gear,and the planetary equipment is utilized to reduce the huge specification and high torque to attain the necessary input torque.they can be utilised for handwheel procedure,sprocket procedure and electric drive gearbox.the gearbox layout have a particular place to meet up with the simultaneous decoding time of the electrical set up when picking different transmission ratios.
The layout normal of the output flange connected with the valve shall be in accordance with ISO 5211.every single specification gives several flange options to satisfy the relationship requirements of the valve.
6.output shaft gap:
According to ISO 5211 common ,the output generate gap can be straight custom-made in various dimensions with no added machining to meet the assembly needs of the valve stem.Offer numerous link strategies,this kind of as multi important relationship,diagonal square 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 safety therapy shall be carried out or the stainless steel material shall be utilized directly .the lock system and 2-inch handwheel block driving areas can be specified .In accordance to the valve torque,the wheel specification can be selected,so as to meet up with the demands that the operating force of the driving valve is not higher than that specified by the valve.
8.all products are geared up with loc ept unit:
It can be locked at any time when the internet site demands to meet the needs of the wor ept problems
