NEUGART high load planetary gearbox product features

Industry news|2022-04-16| admin

The NEUGART brand has a history of nearly 100 years. It initially produced precision gears. Until the 1960s, it began to produce planetary gearboxs. It has always adhered to this high-precision concept. The precision gearboxs produced have a wide range of applications in laser cutting, industrial automation and other industries. , Today I will introduce the characteristics of NEUGART planetary gearbox.

1) Reduce the speed while increasing the output torque. The torque output ratio is based on the motor output multiplied by the reduction ratio, but be careful not to exceed the rated torque of the gearbox.

2) The inertia of the load is reduced while decelerating, and the reduction in inertia is the square of the reduction rate. As you can see, GM has an inertia value. 2 kinds

Universal gearboxs include helical gear gearboxs, precision planetary gearboxs, servo special planetary gearboxs, right-angle planetary gearboxs, planetary gear gearboxs, helical gear gearboxs, powerful gearboxs, precision gearboxs, cycloid gearboxs, Worm gear gearbox, planetary friction mechanical continuously variable transmission, etc.

Generally divided into three types according to the number of stages: first-stage deceleration (generally less than 10), second-stage deceleration (generally greater than 10:1 but less than or equal to 64), third-stage deceleration (some brands do not have a third-stage, the maximum reduction ratio is 512).

By usage: military and civilian;

According to the operating environment: standard environment, low temperature environment, clean room environment, vacuum environment;

According to precision: standard precision and high precision.


NEUGART planetary gearbox has the advantages of high cost performance, wide application, economical and practical, and long service life. In the application of servo control, it exerts good servo rigidity effect, precise positioning control, and has the characteristics of medium and low backlash, high efficiency, high input speed, high input torque, stable operation and low noise of the operating platform.

And the appearance and structural design are light and compact. Lubricating oil that can be replaced for life, and no matter where it is installed, it can avoid maintenance and operation, and the protection level is IP65, which can be used in harsh working environments. Robot industry, as well as electromechanical product automation industry.

This product has the advantages of compact structure, small return clearance, high precision, long life and large rated output torque. But the price is slightly more expensive. 4 application areas

Planetary gearboxs can be directly mounted on AC and DC servo motors and are widely used in medium-precision industrial fields. Such as: printing machine tools, flame cutting, laser cutting, CNC machine tools, tool machinery, food packaging, automation industry, aerospace, semiconductor equipment, medical equipment, robots, manipulators, communication equipment, pharmaceutical equipment, printing equipment, packaging machinery, textile machinery , CNC machine tools, CNC pipe bending machines, parking equipment, measuring equipment, machine tools, precision monitoring systems, vehicle industry, etc.

Torque=9550×motor power÷motor input speed×speed ratio×use coefficient

Remarks: Motor power unit [Kw]

Motor speed unit [rev/m]

Output torque unit [n m]

The motor utilization factor is the ratio of motor power to equipment power. In use, the coefficient should be selected according to the situation. But the bigger the better, because that would be wasteful. In general, if the impact of smooth operation is not large, the service factor is greater than or equal to 1.2. If there is no impact, as long as it is greater than or equal to 1, it runs smoothly. 6 Installation methods

Correct installation, use and maintenance of planetary gearbox is an important link to ensure the normal operation of mechanical equipment. Therefore, when installing the planetary gearbox, please carefully assemble and use it in strict accordance with the following installation and use related matters.

first step

Before installation, confirm whether the motor and gearbox are in good condition, and strictly check whether the dimensions of the parts connected between the motor and the gearbox match. The following are the dimensions and fit tolerances of the motor's positioning boss, input shaft, and reduction groove.

second step

Unscrew the screw on the dust hole on the outer side of the gearbox flange, adjust the PCS system clamping ring so that the side hole is aligned with the dust hole, and insert the hexagonal socket to tighten. After that, remove the motor shaft key.

third step

Connect the motor to the gearbox naturally. When connecting, make sure that the concentricity of the output shaft of the gearbox and the input shaft of the motor is the same, and the outer flanges of the two are parallel. Due to inconsistent concentricity, the motor shaft will break or the reduction gear will wear out.

In addition, during installation, it is forbidden to hit with a hammer to prevent excessive axial force or radial force from damaging the bearing or gear. Be sure to tighten the mounting bolts before tightening the pressure bolts. Before installation, wipe the anti-rust oil on the motor input shaft, positioning boss and gearbox connection with gasoline or zinc-sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, preventing unnecessary wear.

Before connecting the motor to the gearbox, the keyway of the motor shaft should be perpendicular to the fastening bolt. To ensure even force, first tighten the mounting bolts in any diagonal position, but not tight, then tighten the mounting bolts in the other two diagonal positions, and finally tighten the four mounting bolts one by one. Finally, tighten the bolts. All fastening bolts should be fastened and checked with a torque wrench according to the marked fastening torque data.

The correct installation between the gearbox and the mechanical equipment is similar to the correct installation between the gearbox and the drive motor. The key is to ensure that the concentricity of the output shaft of the gearbox is consistent with the concentricity of the driven part of the shaft.
