Greenhouse motor design parameters and principles

The greenhouse motor is a relatively common electrical equipment used in the greenhouse of the multi-span greenhouse. The quality of the product is directly related to the overall operation stability of the multi-span greenhouse. In recent years, with the development of facility agriculture, the model and performance of geared motors have also been continuously improved and designed, and old products have been gradually eliminated and new products have been introduced.

The new type of reducer for multi-span glass greenhouse is a Venlo type greenhouse general window reducer for window opening and sliding curtain. It adopts aluminum die-casting shell, which has beautiful appearance, light weight (about 20 kg), good heat dissipation performance and output High torque (400 Nm ~ 800 Nm) and low noise. At the same time, the bottom installation and side installation are adopted, which is convenient for installation and reduces the labor intensity of the installation workers.

In addition to the light-weight and high-strength aluminum alloy shell, the greenhouse motor adopts a three-stage helical gear transmission and is lubricated with thin oil. Increased transmission efficiency and service life. This type of greenhouse deceleration motor limit device has two types of impact block type and spring leaf type for customers to choose. The adjustment of the limit is convenient, and the positioning accuracy is high (especially the spring leaf type). It can be adjusted within the range of 1 ~ 60 to control the stop of the motor. And there are double safety switches to ensure safe operation.

The geared motor plays a key role in the construction of the greenhouse, because the greenhouse sliding motor must drive the shading net or insulation net and open the window in the whole greenhouse.

The working principle of the greenhouse motor is: the reduction gear motor drives the drive shaft to rotate, and the drive shaft drives the A-type gear to rotate. The gear rotation causes the rack to reciprocate. Because the rack and the push-pull rod are integrated, the push rod and the rack move at the same time. The driving edge profile and the push-pull rod are connected by a push rod connection card, and one end of the sunshade curtain is fixed on the driving edge profile, so the sunshade curtain follows the reciprocating motion of the driving edge profile to realize the unfolding and collapsing action of the sunshade curtain. So once the consequences of the damage are unimaginable, please follow the instructions for correct use.
