Product Description:

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 kind of reducer is better for horizontal multi joint robot?
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 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 drive, rigid robot drive buffer stroke in place shorter and small RV reducer.
Q:When the worm gear reducer works, does the motor have direction?
Reducer in the prime mover and working machine or actuator between the matching speed and torque transfer role, reducer is a relatively precise machine, the purpose of using it is to reduce speed, increase torque
Q:Calculation method of speed ratio of reducer
4, belt, chain and friction wheel gear ratio calculation method: reduction ratio = driven wheel driving wheel diameter, diameter, worm screw lift product description.
Q:Transmission power problem of reducerFor example, a reducer
The speed reducer itself has a certain rated torque and a certain speed ratioWhen N is reduced, the P is reduced to ensure that the output torque of the reducer is less than the rated torque
Q:Transmission power of jzq500 reducer
High speed shaft speed is not greater than 1500 revolutions per minute. Working environment temperature of-40 degrees Celsius to 45 degrees celsius. Because the box structure is horizontally divided and totally enclosed, the mechanical property is good, the work is reliable, and the maintenance is convenient, etc.. This machine has been unanimously affirmed by the customers of heavy machinery industry. The utility model also has the advantages of high overload capacity, shock resistance and small inertia moment, and is suitable for lifting frequently and directly and reversely.
Q:Why is the rotation direction of the input shaft and the output shaft of the cycloidal pin gear reducer the same direction?
The cycloid pin gear reducer is a novel transmission device that uses the planetary transmission principle and uses cycloidal gear teeth to mesh. The whole drive device of the cycloid pin gear reducer can be divided into three parts: the input part, the deceleration part and the output part. Double eccentric sleeve is provided with a dislocation of 180 degrees on the input shaft, the eccentric sleeve is provided with two known as the roller bearing of the rotary arm, formation mechanism, H two is the center hole of the cycloid raceway of bearing eccentric sleeve, and by a group of pin tooth cycloidal gear and annular arrangement the needle on the gear meshing, to form a tooth for tooth difference internal gear reducer, (in order to reduce friction, gear ratio in small, with a needle tooth pin gear).
Q:What is the main reducer of hypoid gear? What are its characteristics?
Some also called hypoid gears hypoid gears or hypoid gear, is a kind of spiral bevel gear, bevel gear is generally perpendicular to the axis of the intersection, while the hypoid gear is perpendicular to the axis of the disjoint, have a certain amount of bias.
Q:Selection of couplings between reducer and main shaft
The output torque of the retarder is the rated torque that he can bear. It is not your actual output, how much 1.5KW motor can do! Don't get me wrong!
Q:Why can the speed reducer improve the output torque?
So generally as a constant, angular speed and torque is inversely related to the reducer after deceleration, w decreases, T will naturally become larger.
Q:What's the reducer? The speed ratio is 1:2
1 calculation methods, definition: speed = input / output speed speed.2 calculation methods, general reduction rate = 9550 / / use the torque motor power motor power input speed, using coefficient, using MB CVT note.3 calculation methods, gear reduction rate = number of teeth, gear driven gear tooth number (if it is a multistage gear, then all the meshing of a gear group driven gear / gear tooth number, and then will be the result of multiply, NRV reducer.4, belt, chain and friction wheel gear ratio calculation method: reduction ratio = driven wheel driving wheel diameter, diameter, helical gear reducer, cycloid reducer to add lubricating oil.
