With the development of science and technology, the development of reducer is closely related to the application history of reducer. The two are complementary. The development of the reducer makes the reducer widely used. It is precisely because the reducer is widely used that the reducer has been developed. In fact, when the reducer was born, it was valued by various engineering construction fields. Reducer is actually a kind of power transmission mechanism, which does not generate power itself. Its function is to reduce the rotation number of motor (motor) to the required rotation number by using different gear sizes and speed converters, and to obtain a mechanism with larger torque. At present, the reducer is widely used in the transmission of power and motion. What is the reducer? Some people have a question, is it OK to directly adjust the speed of the motor? In fact, it is not the same. When the speed of the reducer is changed, it will get a larger torque mechanism. The motor is directly connected to the equipment. When the equipment is running, the load of the motor is very large, so the damage to the motor is also very big. But after the reducer, it is different. For example, for the reducer with a reduction ratio of 100, the load on the motor when the machine is running is only one percent, which is not obvious. Besides, its better to replace the lower gear when the reducer is replaced. The cost is much lower than that of the motor. Once the motor is broken, its useless. At present, the reducer is widely used in the transmission of power and motion. For example, the gear reducer can be seen in almost all kinds of mechanical transmission systems, from ships, cars, locomotives, heavy machines and tools for construction, the principle of bicycle is similar to the ...
What is the reducer? What is the application of reducer? Do we need to know about the reducer? Whats wrong with our knowledge of reducer? With these questions raised, today we go into the depth of this article and the reducer, understand the reducer, and briefly analyze the reducer! First of all, reducer is a general term. Under the name of reducer, there are thousands of reducer classification and application. According to the different working principles and application aspects of these reducers, they want to have their own names accordingly. The reducers mentioned in our article belong to one of them! Secondly, the reducer is not an independent machine. Its main work is mainly on power equipment such as motor and engine, and the function of reducer beside it is equivalent to a protector or a regulator. Control and protect the normal operation and better operation of the engine. Although it doesnt look like much? But the function and importance of the reducer can not be underestimated. The machine with the reducer is not so powerful, but it is also a multiplier effect with half the effort. With the development of some industries, the reducer is also constantly entering our lives. ...
IPX is the same as JIS of American manufacturing floor waterproofing standard, which is divided into 9 grades of 0-8, and recorded here. Level 0 no protection Level 1 can also eliminate the harmful effect of small water drops falling vertically Level 2 has safety protection function for water drops falling down within 15 degrees from vertical angle The 3 stage also removes the harmful effects of spray droplets with a vertical angle of 60 degrees. Level 4 also eliminates the harmful effects of splashing water from other directions Level 5 can also remove the harmful consequences of the spray water from all directions Level 6 can also remove the harmful and adverse effects on the super strong water volume of the nozzles in all directions The top of level 7 is 0.15-1m away from the water surface, lasting for 30 minutes, with no adverse effect on the service performance and no water leakage The top of Grade 8 is 1.5-30 meters away from the water surface, lasting for 30 minutes, with no adverse effect on the service performance and no water leakage In the future, we should pay attention to the three prevention mobile phones. Only the 7-level and 8-level mobile phones are really waterproof; the 6-level mobile phones can make do with the rain, and the outdoor mobile phones and GPS still need to reach this level. ...
Use requirements: The performance and effect of the anti falling safety device of the construction elevator directly affect whether the construction elevator can be used safely. In order to ensure the effectiveness of the anti falling safety device, regular inspection is essential. What are the specific requirements of the national standards for the inspection period and service life of the anti falling safety device of the construction elevator? According to the construction industry standard of the peoples Republic of China construction elevator gear cone drum progressive anti falling safety device (jgl21-2000), construction elevator anti falling safety device can only be used within the valid inspection period. The valid inspection period of the safety device shall not exceed two years. Whether the safety device is used or not, it must be re calibrated after the expiration of the effective inspection. These safety measures are to ensure the safe use of construction elevators and prevent safety incidents. (gb10055-2007 safety regulations for construction elevators 11.1.9 stipulates that the anti falling safety device can only be used within the valid calibration period, and the valid calibration period shall not exceed one year. ) Detection protection: In order to ensure the safety of the construction elevator, we must verify the anti falling safety device every 1-2 years. What verification equipment and items should be used in the verification of the anti falling safety device? According to the understanding of Dacheng Construction Machinery Co., Ltd., at present, the test-bed for the inspection and calibration of the anti falling safety device generally needs the performance tester, stepless speed regulating device, torque and speed sensor, microcomputer type torque...
