Geared motors

Find the product for your application!

We offer a wide variety of geared motors: Helical, parallel, and bevel gears and of course the special NORD BLOC and UNIVERSAL products.

As early as the 1980s, NORD developed the most important innovation in gear unit construction to the present day. The unicase concept. All bearing holes and sealing surfaces are machined in a single stage on the latest CNC centres.

Q: What is the principle of worm gear reducer?: The motor drives the worm to rotate, and the turbine shaft outputs. According to the different reduction ratio, the worm rotates several circles, and the turbine rotates one circle to achieve the purpose of slowing down.

Q: How do I choose the reducer ah, consult an expert, a little more detailed, thank you: The speed regulating motor is a kind of motor that changes the speed of the motor by changing the series, voltage, current and frequency of the motor so as to make the motor achieve higher performance.

Q: What is called a reducer, two speed reducer? I'm talking about two times a time, not a level two, do not copy paste: Generally speaking, are based on the gear reducer to transfer movement, in the reducer in the drive shaft and the driven shaft are respectively assembled at all levels, top gear, the gear meshing transmission to achieve different speed. The gear ratio is equal to the ratio of the product of the rotational speed products at all levels and the product of the rotational speed at all levels. It is also equal to the ratio of the number of driven teeth at each level to the product of the active gear at all levels. If the reducer has only one driving gear (sheathed on the drive shaft, driven by an electric motor), a driven gear (output motion) is kneaded, which is a primary deceleration, that is, a deceleration. If the driven gear in it engages with another gear (the gear moves out), then the two step slows down. Deceleration is not only level one or level two, it can have many levels. Since the number of teeth and a gear transmission ratio, and also indirectly related to the size of the gear, if you need great speed gear may have to do a lot, this is not only a waste of raw materials, but also to support the gear shaft strength have higher requirements, so in the case of very large gear in general, will adopt multi speed.

Q: What is the function of the reducer? Do you want the motor to stop?: 2) reduce the inertia of the load at the same time, reduce the inertia as the square of the reduction ratio. You can look at the general motors have a value of inertia.

Q: What's the connection between the reducer and the motor, and the difference? Thank you!: Reducer is a power transmission mechanism, the use of gear speed converter, motor (motor) to reduce the number of turns to the desired number of turns, and get a larger torque mechanism. At present, the reducer is widely used in the transmission of power and motion. See it all in almost all kinds of mechanical transmission system, from ships, transport vehicles, locomotives, heavy equipment for construction, processing machinery and automated production equipment used in machinery industry, household appliances, common daily watches and so on. The application of power transmission from the work, to small load, accurate transmission angle can meet the application of speed reducer, and in industrial applications, speed reducer has to slow down and increase torque function. Therefore, it is widely used in speed and torque conversion equipment.

Q: What is the function of the reducer?: What is a reducer?Reducer is a power transmission mechanism, the use of gear speed converter, the number of motor rotation slowed to the desired number of turns, and get a larger torque mechanism.

Q: After the reducer deceleration power is improved?: Motor with speed reducer is in order to improve the torque, when the load is large, a taste of the power to improve the servo motor is not cost-effective, so the need for speed range selection of gear ratio reducer for the reducer itself is to slow down and increase the output torque effect.

Q: 1- gets low speed, and 2- gets high torqueIn addition to the above 2 reasons, what are the reasons? Some people say that in order to obtain better operating characteristics, I do not understand this meaning, please give detailed explanation of the professionals, thank you: 3 reducer have protective effects in motor drive, running speed reducer under high overload torque, when delivered to the motor overload only divided by reduction ratio value, if directly by motor bear may cause the damage to the motor. When the overload is very large, the deceleration opportunity is damaged first, and the reducer needs to be replaced only when the spare parts are replaced. The cost is relatively low. If the motor is directly damaged, the maintenance is relatively slow and the cost is high.

Q: I need to have a speed reducer drives a crank link system, through the calculation of the maximum load for the crank system I need to choose the reducer output torque of 400N.m. is bigger than 400N.m? Or to first calculate the load multiplied by a safety factor of 1.6 for 400*1.6=640N.m, and then select the output torque of reducer about more than 640N.m?: If you run the linkage system more stable, there is no need to add the coefficient, because the reducer itself has the overload coefficient, and coefficient is: working machine is more complex, but with a peak load.Of course, I'm on the safe side. I suggest you choose the 1.1~1.2 of the maximum load on the connecting rod when you select the torque output of the reducer.

Q: What are the features of a harmonic reducer? If I need a speed ratio. When the torque is constant. Require smooth mechanical operation, no inertia.: I know a little bit more about the planet. I can understand the harmonics. I hope I can do it.The utility model has the advantages of light weight, large reduction ratio, high position precision and repeated positioning precision, small volume, high torque output, no empty return, high transmission efficiency and low noise. In general, the original principle of meshing is completely different from the ordinary gear meshing, so it can achieve no backlash, micro feed and high repeatability positioning accuracy.
