High efficiency Low backlash(1arc min)differential gear box is a new generation of practical products independently developed by our company:
Low noise: less than 65db.
Low back clearance: up to 3 arc minutes in a single stage and 5 arc minutes in a double stage.
High torque: higher than the standard planetary reducer torque.
High stability: high strength alloy steel, the whole gear after hardening treatment, not only the surface hard substitution.
High deceleration ratio: Modular design, planetary gearbox can be interlinked.
With a standardized flange interface, the PSFN is easy to install and safe. Due to the high anti-tilt torque, this precision planetary reducer can complete many difficult tasks. Its advantage is: this planetary reducer even at the highest speed can achieve the highest efficiency, very suitable for high standard production conditions, a really strong and reasonable price products.
Gear material is made of high quality alloy steel, carbon - nitriding treatment, so as to obtain the best wear resistance and impact toughness. ANSYS technology is used to carry out finite element analysis on the strength of the gear, and trim the tooth surface shape and lead, so as to reduce the impact and noise of gear meshing and increase the service life of the gear train. The output planetary frame adopts the integrated structure design (double support), and the front and rear bearings are distributed in the box with large span, forming a stable integrated structure to ensure higher torsional rigidity and accuracy.
The gear ring and the output shell adopt the integrated design, using high quality steel, after hot forging forming, so as to obtain a higher material density. The integrated design ensures that all geometric dimensions are finished in one go, with higher precision and strength compared with other embedded and clamped structures. The input shaft and the locking device adopt the integrated design, the double bolts are symmetrical distribution, achieve dynamic balance at the same time, through the strong locking of the double bolts, effectively prevent the electric shaft drive from slipping, to achieve high precision and zero backgap power transmission.
Compared with other reduction machines, planetary gear reduction machines have high rigidity, high precision (single stage can be achieved within 1 point), high transmission efficiency (single stage in 97-98%), high torque/volume ratio, lifetime maintenance free and other characteristics.
Because of these characteristics, planetary gear reducer is mostly installed on the stepper motor and servo motor, used to reduce speed, increase torque, matching inertia.
Q:Key points of selection of planetary reducer
A:1. Frame number determined by torque: the power source will have the effect of torque amplification after deceleration ratio. The output torque value of the reducer is proportional to the deceleration ratio, and the larger the ratio, the higher the torque value will be; But the gear group of the reducer has the limit, so the rated output torque of the planetary reducer is to say that the product can work stably under the data operation, so the box number must be selected according to the demand torque.
2, according to the accuracy to determine the model: in the process of automation will need positioning, when the positioning accuracy requirements are higher, you need to choose a higher level of products, and vice versa. The precision of the planetary reducer is called the "backgap", which refers to the gap of the gear group. The definition is the Angle value that the output shaft of the planetary reducer can rotate when the input end is fixed. The smaller the return clearance is, the higher the accuracy is and the higher the cost is. The user can choose the right accuracy according to their actual situation.
3, according to the installation size selection: that is, the size of the front end of the servo motor. The input end of the planetary reducer must match the output end of the servo motor.
4, according to the appearance selection: according to customer demand output shaft and connecting surface has a standard series for users to choose, can also be customized according to user special needs.
5, according to the axial and radial force selection: the life of the planetary reducer is affected by the internal bearing, bearing life can be calculated through the load and speed, when the axial and radial force load of the reducer is higher, the bearing life will be shortened, at this time it is recommended to choose a large product.
