Features of DSZR series helical gear motor:

1. Highly modular design: various types of motors or other power inputs can be conveniently used. The same type of machine can be equipped with multiple power motors. It is easy to realize combination and connection between various models.

2. Transmission ratio: fine division and wide range. The combined model can form a large transmission ratio, that is, the output speed is extremely low.

3. Installation type: unlimited installation position.  

4. High strength and small volume: the box is made of high-strength cast iron. Gear and gear shaft adopt gas carburizing, quenching and fine grinding technology, so the bearing capacity per unit volume is high.

Long service life: under the conditions of correct model selection (including selection of appropriate service factor) and normal use and maintenance, the service life of main parts of the reducer motor (except vulnerable parts) is generally not less than 20000 hours. Wearing parts include lubricating oil, oil seal and bearing.

6. Low noise: the main parts of the reducer have been precision machined, carefully assembled and tested, so the noise of the reducer is low.

7. It can bear large radial load.

DSZR.. Type: The combination of the two models can form a large transmission ratio, and can also be combined with R series reducer, DSZK series reducer, DSZS series reducer, DSZF series reducer.

Compared with the transmission of cylindrical gear reducer, planetary gear reducer has many unique advantages. Its most remarkable characteristics are: when transmitting power, it can conduct power diversion; At the same time, the input shaft and the output shaft are coaxial, that is, the output shaft and the input shaft are set on the same main axis. Therefore, planetary gear reducer drive has been used to replace ordinary gear drive, and as a speed increaser and speed reducer in various mechanical transmission systems.

The main features of planetary gear reducer transmission are as follows.

1. Stable movement, strong resistance to impact and vibration. Because several planetary gears with the same structure are used and evenly distributed around the center wheel, the performance force of the planetary gear and the rotary arm can be balanced. At the same time, the coaxial reducer also increases the number of teeth involved in meshing, so the planetary gear transmission has stable movement, strong resistance to impact and vibration, and reliable operation.

2. The transmission ratio is large, which can realize the synthesis and decomposition of motion. As long as the type and gear matching scheme of planetary gear transmission are properly selected, a large transmission ratio can be obtained with a few gears. In the transmission of planetary gear reducer, which is only used to transmit motion, its transmission ratio can reach thousands. It should be pointed out that when the transmission ratio of planetary gear transmission is large, it can still maintain many advantages such as compact structure, small mass, small volume, etc. Moreover, it can also realize the synthesis and decomposition of motion and various complex movements with variable speeds.

3. The planetary gear reducer has small volume, small mass, compact structure and large bearing capacity. Because the planetary gear transmission has the power diversion, the central wheels form a coaxial transmission, and the rational application of internal meshing gear pairs, it can make its structure very compact. Moreover, because several planetary gears are evenly distributed around the center wheel to share the load, the load borne by each gear is smaller, and smaller modules are allowed for these gears. In addition, the coaxial reducer makes full use of the large internal meshing bearing capacity and the volume of the internal gear ring itself in structure, which is conducive to reducing its overall size, making it small in volume, small in mass, very compact in structure and large in bearing capacity. Generally, the overall dimensions and mass of planetary gear transmission are about 1/2~1/5 of that of ordinary gear transmission (i.e. under the same load conditions).

4. The high transmission efficiency of planetary gear reducer is due to the symmetry of the planetary gear transmission structure, that is, it has several evenly distributed planetary gears, so that the reaction forces acting on the center wheel and the rotary arm bearing can be balanced, which is conducive to improving the transmission efficiency. The efficiency value can reach 0.97~0.99 when the transmission type is properly selected and the structure layout is reasonable.
