CN203087110U - Single-axial-direction curtain rolling machine provided with few-tooth-difference reducer and used for greenhouse - Google Patents

Abstract

The roller shutter machines currently in use all use multi-axis gear reducers. The power of the motor is input to the reducer through the belt pulley and then the output shaft of the reducer is used to rotate the curtain of the greenhouse. Its disadvantage is the weight of the machine, and the V-belt is easy to age. The roller blind machine equipped with a small-tooth-difference reducer for uniaxial greenhouses of the utility model is an eccentric shaft in a small-tooth-difference reducer connected by an electric motor, and a group of planets are arranged on the eccentric shaft. When the motor rotates, it drives the multi-toothed gear in the planetary set on the eccentric shaft to rotate along the fixed internal teeth. At the same time, the few-toothed gear of the planetary gear set also rotates synchronously to drive the internal gear of the output shaft. The difference in the number of teeth of the two gears is used to achieve the purpose of deceleration.

Description

Roller shutter machine with small tooth difference reducer for uniaxial greenhouse

technology field;

The utility model relates to a roller blind machine for agricultural greenhouses, in particular to a roller blind machine equipped with a reducer with less tooth difference for single axial greenhouses. the

Background technique;

The roller shutter machines currently in use all use multi-axis gear reducers. The power of the motor is input to the reducer through the belt pulley and then the output shaft of the reducer is used to rotate the curtain of the greenhouse. The motor and the reducer are installed together on the frame to form the body assembly of the roller blind machine and then connected to the rocker arm. The problem of the original roller blind machine is that it is heavy and the manufacturing cost is high. The main disadvantage is that the V-belt used for the transmission between the motor and the reducer is easily aged and damaged by the wind and the sun. the

Utility model content;

The roller blind machine equipped with a small tooth difference reducer for uniaxial greenhouses of the utility model is characterized by light weight and compact structure, and the most important thing is that the V-belt without rubber is easy to age when exposed to the sky, and the manufacturing cost is low. Also relatively low. The main feature of the utility model is that the reducer with less tooth difference is directly connected before the motor, and the output shaft of the reducer with less tooth difference directly rolls the blind shaft. the

The roller blind machine equipped with a small-tooth-difference reducer for uniaxial greenhouses includes an eccentric shaft in a small-tooth-difference reducer connected to a motor. The eccentric shaft is equipped with a set of planetary gears. When rotating, it drives the multi-toothed gear in the planetary set on the eccentric shaft to rotate along the fixed internal teeth, and at the same time, the gear with few teeth in the planetary gear set also rotates synchronously to drive the internal gear of the output shaft. Because the two gears in the planetary gear set The difference in the number of teeth to achieve the purpose of deceleration .

Description of drawings;

Fig. 1 is the concise schematic diagram of the utility model;

Fig. 2 is the basic structural representation of the utility model;

Fig. 3 is a schematic diagram of the utility model when installed in a greenhouse. the

Detailed ways;

The utility model is described in further detail below in conjunction with the accompanying drawings. the

As shown in the figure, the roller blind machine equipped with a small tooth difference reducer for uniaxial greenhouses includes a planetary gear set 1, a fixed internal gear 2, and an output shaft internal gear 3 that is integrated with an output shaft 4 , the eccentric shaft 5 is connected with the rotating shaft 6 of the motor through a key pin, 61 is the motor which is fixed on the housing 9 of the reducer through a screw, 8 is a bushing, 7 is a roller shutter shaft, 71 It is a greenhouse curtain, and 10 is a refueling hole of the speed reducer, and 11 is a hole for pressing the rocking arm, and the rocking arm 12 is installed on the base frame 13, and the 14 is a greenhouse, and the 15 is a greenhouse curtain. the

Claims (2)

1. Single shaft to the roller shutter machine that little tooth difference speed reducer is housed used of booth, it comprises the interior eccentric shaft of little tooth difference speed reducer that an electromotor is joining, one group of planet tooth is housed on the described eccentric shaft, when electromotor rotates, multiple tooth gear in the planetary set on the drive eccentric shaft is along fixedly internal tooth rotation, few gear of planetary gearsets also rotates the internal gear that drives output shaft synchronously simultaneously, because the number of teeth difference of two gears in the planetary gearsets reaches the deceleration purpose.
2. As right 1 described single shaft to the roller shutter machine that little tooth difference speed reducer is housed used of booth, it is characterized in that on the shell of described little tooth difference speed reducer a rocking arm hole being arranged, it stretches into rocking arm and uses by dress the time.
