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 relationship between the car separator and the main reducer? What parts does the power output go through when the gearbox comes out?: If is a four-wheel drive, power from the transmission to the actuator, to drive bridge, half shaft, and finally to the wheel, transmission, actuator, transmission shaft drive axle are connected between the power to the four wheels, called four-wheel drive

Q:How do you choose the speed reducer when you know the input speed and power of the motor?: It is necessary to know the actual speed, power and mechanical efficiency of the working conditions, and then select the speed ratio, the mechanical efficiency and the power of the reducer to match the motor according to these conditions.

Q:What does the speed reduction ratio of the stepper motor mean?: The general reduction ratio is represented by 1 as the denominator, with ":" to connect the ratio of the input speed and output speed, such as the input speed of 1500r/min, the output speed of 25r/min, then its reduction ratio is: i=60:1. Gear reduction ratio is generally marked the actual reduction ratio, but some special reducer such as cycloid reducer or harmonic reducer, sometimes with rounding rounding, and not as the denominator, the actual reduction ratio may be 28.13 marked, generally marked 28.

Q:What is the function of the main reducer?Don't say it's slowing down. Just say why!: The main reducer must be independent of the transmission gear, for the simple reason that the main reducer is equipped with differential gears

Q:How to remove the reducer of the double cylinder washing machine?: 2. Screw out the impeller screw, take out the impeller, then screw out the big nut of the fixed inner barrel with the special sleeve (Q818, Q828 model, the inner barrel is fixed with four M6 bolts) and take out the inner barrel;3, on the ground, first put a soft cloth, the washing machine side upside down, with a sleeve spin out two fixed clutch on the protection of the bolt, take off the protection frame;4. Unscrew the four bolts of the clutch with a sleeve, take the belt, and finally take out the clutch and replace it with the new clutch;5 assemble the original steps.

Q:How many kinds of reducers can be divided into?: 2) harmonic drive of harmonic reducer is to transfer the motion and power by means of elastic deformation controlled by flexible elementsSmall, high precision, but the disadvantage is that flexible wheel life is limited, not shock resistant, rigid and metal parts are relatively poor. Input turnSpeed can not be too high.

Q:Working principle of harmonic reducer: Among them, the number of teeth of rigid wheel is slightly larger than the number of teeth of flexible wheel.The length of the wave generator is larger than diameter of the flexspline undeformed: when the wave generator is arranged inside the inner circle of the flexspline, forcing the flexspline generates elastic deformation and oval shaped, the long axis at the flexspline tooth groove insert rigid wheel, become fully engaged; and the short axis of the two wheel tooth no contact is in the disengaged state. The process of engaging or disengaging is in an out or out state.

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?: The reducer is a kind of independent parts enclosed by a rigid shell gear, worm gear, gear - worm gear reducer, commonly used as a prime mover and work machine. It plays an important role in matching speed and transmitting torque between prime mover and working machine or actuator, and it is widely used in modern machinery.

Q:How big is the maximum two stage retarder?: The cylindrical gear reducer is the most widely used in all reducers. It can transfer power from small to 40 000kW, the circumferential velocity can also be from a low to a 60m/s 70m / s, even up to 150m / s. The reducer with large transmission power is best to use dual drive or central drive. The two kinds of arrangement can be shared by two pairs of gear pairs, which is beneficial to improve the force condition and reduce the transmission size. In the design of double drive or center driven gear drive, automatic balancing device should be adopted to make the load of gear pair be evenly distributed, for example, sliding bearing and elastic support.

Q:Single stage cylindrical gear reducer, the total efficiency of the drum by the efficiency of it, why?: The drum is also supported by the shaft, which consumes part of the power, and the final speed required by the working machine is the speed of the roller movement
