Abstract

Multi-shaft gear reducers are used in all currently used curtain rolling machines, motive power of motors is input to the reducers through belt pulleys and then curtain of greenhouses are rotated through output shafts of the reducers. The curtain rolling machines have the disadvantages that a machine body is heavy and a triangular belt is prone to aging. The utility model provides a single-axial-direction curtain rolling machine provided with a few-tooth-difference reducer and used for a greenhouse. A motor is connected with an eccentric shaft inside the few-tooth-difference reducer, and a set of planetary gears is installed on the eccentric shaft. When the motor rotates, a multi-tooth gear in the planetary gear set on the eccentric shaft is driven to rotate along a fixed inner gear, and at the same time, a few-tooth gear in the planetary gear set rotates synchronously to drive an output shaft inner gear. The purpose of reducing speed is achieved through the gear tooth difference between the two gears in the planetary gear set.

Description

Single shaft to the roller shutter machine that little tooth difference speed reducer is housed used of booth

Technical field;

The utility model relates to agricultural greenhouse roller shutter machine, especially relate to single shaft to the roller shutter machine that little tooth difference speed reducer is housed used of booth.

Background technology;

All be the gear reduction unit of using multiaxis at the roller shutter machine that uses at present, the power of motor is the curtain that is rotated booth by belt pulley input decelerator again by reducer output shaft.Motor is installed on the frame with decelerator, is connected on the rocking arm behind the block assembly of composition roller shutter machine again, and the problem of roller shutter machine originally is that weight is big, the cost height of manufacturing.Main shortcoming also has V belt that the transmission between motor and the decelerator uses through exposing to the weather, easily aged deterioration.

The utility model content;

Single shaft of the present utility model to the roller shutter machine that little tooth difference speed reducer is housed used of booth, its feature is in light weight, structure is compact, main is, and not have the V belt of rubber to be exposed at aging easily beyond the highest heavens, manufacturing cost is also relatively low.Principal character of the present utility model is directly to connect little tooth difference speed reducer before motor, the direct curtain rolling shaft of the output shaft of little tooth difference speed reducer.

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

Description of drawings;

Fig. 1 is a simple and clear principle schematic of the present utility model;

Fig. 2 is a basic structure schematic diagram of the present utility model;

Fig. 3 is the schematic diagram when being installed in booth of the present utility model.

Embodiment;

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in the figure, single shaft to the roller shutter machine that little tooth difference speed reducer is housed used of booth, it comprises planetary gearsets 1, fixed annulus 2, it is one with output shaft 4 for output shaft internal gear 3, eccentric shaft 5 and shaft of motor 6 connect together by key pin, the 61st, it is to be fixed on the housing 9 of decelerator by Luo Ding for an electromotor, the 8th, and axle sleeve, the 7th, curtain rolling shaft, the 71st, the booth curtain, the 10th, the tank filler sleeve of decelerator, the 11st, by the hole that the dress rocking arm is used, rocking arm 12 is installed on the pedestal 13, the 14th, booth, the 15th, booth curtain.

Claims

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.
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.
