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: Is the RV reducer used in industrial robots single stage transmission? Calculation method of transmission ratio, thank you!: Excellent technology and more mature and superior, the diameter difference of sub transmission ratio up to infinity (practical for single tooth difference), the volume ratio of two is a harmonic reducer (i.e. the volume modulus is two times harmonic reducer), harmonic reducer and flexible transmission, the diameter difference of sub rigid reducer transmission. The robot motion in place of rigid transmission buffer stroke shorter and small RV reducer. The diameter difference of sub reducer and planetary reducer is less than the efficiency of harmonic reducer and RV reducer, so a lot of harmonic reducer transmission efficiency is lower than 0.8, the diameter difference of sub reducer planetary reducer meshing tooth number is more than five times less than the harmonic reducer and RV reducer, thus the diameter difference sub reducer theoretical accuracy only the higher harmonic reducer reducer is difficult to surpass RV. The radial differential reducer has great transmission power (harmonic reducer, industrial robot load 10Kg, diameter deviation, sub reducer, industrial robot can load 2000Kg). The CNOOC adopts foreign planetary reducer of submersible pump can only use 9 "(228.6mm) and the Shenyang University in Liaohe Oilfield wellhead, the son of your prince Dr. reducer of submersible pump can break 5" (127mm) (i.e. small wellhead diameter is less than 105mm sent a reducer load up to 35KW power). Gd980, SIASUN etc. the intention of contributions received sub diameter difference transmission technology Co Ltd, Japan is one of the development of the robot China pressing big three reducer bottleneck trip.

Q: Types and types of reducers: Reducer is a relatively precise machine, the purpose of using it is to reduce speed and increase torque. It has many kinds and different models. Different kinds have different uses. There are many types of reducer according to transmission type can be divided into gear reducer, worm reducer and planetary gear reducer; according to transmission series can be divided into single and multi-stage gear reducer; according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer; according to the arrangement the form of transmission can be divided into expansion, split and coaxial reducer.

Q: Requirements of the national standard for reduction gearbox design: There are different standards for different types of speed reducers. For example, ZDY, ZLY and ZSY, hardened surface cylindrical gear reducer standard for JB/T8853-2001; DBY and DCY series bevel gear reducer standards for JB/T9002-1999, etc..

Q: How do I choose the reducer ah, consult an expert, a little more detailed, thank you: The acceleration and deceleration device can ensure the output power basically unchanged. If the required speed is constant, use a retarder; not constant; use only the governor. Alternatively, a variable speed output is required, but the speed range is far from the rated speed of the motor, and the speed motor + transmission can be adopted.

Q: What is the principle of Turbo worm reducer?: The utility model has the advantages of large transmission ratio, compact structure, direct arrangement of space, stable, small noise and self locking, and has the disadvantages of large heat generation, large axial force of the input shaft, easy wear and low efficiency.Most of the reducers on the escalator use this transmission

Q: What's the difference or difference between the three reducer, reducer, reducer?: Reducer is a relatively precise machine, the purpose of using it is to reduce speed and increase torque. It has many kinds and different models. Different kinds have different uses. There are many types of reducer according to transmission type can be divided into gear reducer, worm reducer and planetary gear reducer; according to transmission series can be divided into single and multi-stage gear reducer; according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer; according to the arrangement the form of transmission can be divided into expansion, split and coaxial reducer. The following are the commonly used gear reducer categories:The cycloid reducerThe hardened cylinder gear reducerThe planetary gear reducerThe soft tooth surface reducerThe three ring gear reducerCrane reducer.One worm reducer8 shaft mounted toothedsurfacereducerOnly the CVT

Q: What is the function of the reducer?: Types of common reducers1) the main feature of the reducer is the reverse self-locking function, it can have a larger reduction ratio, the input shaft and output shaft are not on the same axis, nor on the same plane. But the general volume is large, the transmission efficiency is not high, the accuracy is not high.2) harmonic harmonic drive reducer is controlled by the flexible components to transfer elastic deformation and dynamic movement, small volume, high precision, but the disadvantage is the soft wheel limited life, impact resistance, rigidity compared with metal. Input speed can not be too high.3) planetary reducer has the advantages of relatively compact structure, small return clearance, high accuracy, long service life, and the rated output torque can be done a great deal. But the price is slightly expensive.

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: What are the uses of the reducer? What are the forms?: Types of common reducers1) the main feature of the reducer is the reverse self-locking function, it can have a larger reduction ratio, the input shaft and output shaft are not on the same axis, nor on the same plane. But the general volume is large, the transmission efficiency is not high, the accuracy is not high.2) harmonic harmonic drive reducer is controlled by the flexible components to transfer elastic deformation and dynamic movement, small volume, high precision, but the disadvantage is the soft wheel limited life, impact resistance, rigidity compared with metal. Input speed can not be too high.3) planetary reducer has the advantages of relatively compact structure, small return clearance, high accuracy, long service life, and the rated output torque can be done a great deal. But the price is slightly expensive.

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.: The robot reducer usually uses harmonic reducer and RV reducer (that is cycloid pin gear reducer). At present, the best is the radial differential reducer (it is evolved from the automobile differential). The process of harmonic reducer, including Japan, has also been improved; RV reducer technology is mature, the crankshaft process is difficult, the diameter difference reducer is sub RV deceleration device is modified to cancel the crankshaft, excellent technology and more mature and superior, the diameter difference of sub transmission ratio can reach infinity (practical single differential gear and ring gear tooth number ratio number), volume ratio is two of a harmonic reducer (i.e. volume modulus is two times harmonic reducer), harmonic reducer and flexible transmission, the diameter difference of sub rigid reducer drive, rigid robot drive buffer stroke in place shorter and small RV deceleration for sub diameter difference decelerator torque small size for each joint of the robot
