Instructions: reducer inspection and maintenance

Under normal circumstances, for long-term continuous operation of the combined gearbox, according to run 5000 hours or once a year to replace the new oil, long-term reducer should be replaced before the re-operation of the new oil reducer should be added with the original brand of the same oil, Do not mix with different grades of oil, the same grades and different viscosity of the oil allows mixed use.
Oil change to wait for the WAH hypoid gearbox to cool down without burning danger so far, but should remain warm, because the complete cooling, the oil viscosity increases, oiling difficulties. Note: To cut off the drive power, to prevent inadvertently power!
Work, when the oil temperature rise above 80 ℃ or oil tank temperature exceeds 100 ℃ and produce abnormal noise and other phenomena should stop using, check the reasons, must be troubleshooting, the replacement of lubricants before they can continue to run.
Users should have a reasonable use of maintenance rules and regulations, the operation of the reducer and inspection found in the problems should be carefully recorded, the above provisions should be strictly enforced.

Gear reducer once the oil spill, not only the formation of capital spoil, and pollution of the environment, severe gear will cause less gear, oil, so that gear meshing
Surface wear aggravated, and then attack biting or stripping, resulting in equipment incidents.
The following general and we talk about gear reducer leakage is caused by what factors. The same time as the above-
1, Hypoid speed gearbox surface pressure difference
Gear reducer during the operation, movement, conflict heating and by the impact of ambient temperature, so that the gear reducer temperature to add, if there is no ventilation holes or
Ventilation holes blocked, then the machine gradually add the pressure, the higher the temperature inside the machine, the greater the pressure difference with the outside world, lubricating oil in the pressure effect, from the gap at the leak
Out.
2, combined worm reducer structure design unreasonable
(1) hole cover plate is too thin, tighten the bolt after the deformation, so that the contact surface is uneven, from the touch gap oil. The same time as the above-
(2) in the production of gear reducer process, the casting is not annealing or aging treatment, without eliminating the internal stress, must occur deformation, the formation of gaps, resulting in
Leaked. The same time as the above-
(3) there is no oil tank on the tank, the accumulation of lubricating oil in the shaft seal, cover, contact surface, etc., in the pressure effect, from the gap to the outside leakage. The same time as the above-
(4) shaft seal structure design is unreasonable. Early reducer more use of oil ditch, felt ring seal structure, assembled when the blankets by the compression deformation, and the
Contact surface gap sealed up. If the journal and seal touch is not very desirable, because the blanks of the compensation function is very poor, sealed in a short time that failure
The Although the oil groove on the oil return hole, but easy to block, oil effect is difficult to show.
3, gear reducer fuel too much
 Gear reducer in the course of operation, the oil pool was stirred very ferocious, lubricants in the machine everywhere splash, if the fuel is too much, so that a lot of oil product
Gathered in the shaft seal, contact surface, etc., resulting in leakage.
4, gear reducer repair technology is wrong
In the equipment maintenance, because the contact surface dirt removal is not complete, or sealant selection is wrong, the direction of the seal installed, not timely replacement of seals, etc.

variable ratio gearbox for the gear reducer, according to the current situation, China's gear reducer from the beginning of the development of China to the present, the original effect is not very obvious, there is no change in the form of production, compared with this form, Many foreign gear reducer companies will rely on skills, management, capital and other aspects of the advantages of the unique shopping malls share, and gradually enter the Chinese reducer mall. Facing foreign goods in the Chinese reducer market strong to seize, China's reducer industry is facing a severe shopping malls crisis, and this crisis is also a major impact on the domestic reducer company, to promote its time to form a contend Competition form, and gradually in the skills, processing has increased investment, and strive to compete in foreign goods, to defend the domestic reducer shopping malls.
The world mall needs for heavy machinery and spare parts will also be added. With the gradual recovery of economic recovery in Europe and the United States, the establishment of the real economy in the national economy from the location, as well as the construction of the country's basic construction needs, heavy machinery in the world of shopping malls will have more room for development.
The reducer is a power transmission mechanism that uses its intention to drop the speed and add torque. Its variety is complex, different types, not the same species have different uses. Heavy-duty mechanical reducer planning of the goods include a variety of large industrial gearbox, planetary gear reducer, worm gear reducer and cycloid reducer, also contains a variety of special drive.
According to the industry summary, reducer with relatively large amount of occupation are: power machinery, metallurgical machinery, environmental protection machinery, electrical appliances, road machinery, chemical machinery, food machinery, light industry machinery, mining machinery, transport machinery, construction machinery, Building materials machinery, cement machinery, rubber machinery, water machinery, oil machinery

 The reducer is suitable for industrial sectors such as lifting and transportation, engineering machinery, metallurgy, mining, petrochemical, construction machinery, light industry and textile, medical equipment, instrumentation, automobile, ship, weapon and aerospace. What are the main causes of common failure of the helical bevel worm gearmotor?
Common malfunctions
As the combined worm reducer operating environment is bad, often wear and tear, leakage and other failures, the most important are:
1, reducer bearing chamber wear, which also includes the shell bearing box, the box hole bearing chamber, gearbox bearing chamber wear;
2, reducer gear shaft shaft wear, the main wear parts in the shaft head, keyway, etc .;
3, reducer drive shaft bearing bit wear;
4, reducer joint surface leakage.
