Abstract
The utility model relates to a gear rack transmission mechanism for opening windows of greenhouses. The utility model is composed of gear wheel welding 1, gear rack welding 2, lateral plates 3, a fixed shaft 4, a spacing ring 5, spacing wheels 6, nuts 7, a window body 8, and a driving shaft 9. The gear rack welding 2 is hinged with the window body 8 through a hinging barrel. Two lateral plates 3 are arranged on both sides of a shaft shoulder of the fixed shaft 4. The number of the spacing wheel 6 is two, and the spacing wheels are positioned on the inside of the groove of a U-shaped groove gear rack. The corresponding position of the gear rack and the gear wheel is controlled by the lateral plates 3, the spacing ring 5 and the spacing shell 6. The utility model has the advantages of simple structure, easy production and manufacture, reliable driving, convenient assembly and disassembly, etc.
Description
The utility model is a kind of greenhouse tooth bar transmission windowing facility, and is particularly a kind of by the spacing gear of two running rollers, tooth bar transmission window-opening mechanism.
In the prior art, with the utility model the most close be the U type groove punching tooth bar that French Rui Qi company adopts, spacing employing be one-body molded steel bushing structure or plastic pad position limiting structure (two types), in motion process, be sliding friction with tooth bar, produce big noise.Engaged transmission mode in the rack-and-pinion that agricultural research adopts of Shanghai City, gear are installed in the tooth bar top.
The purpose of this utility model is the tooth bar transmission windowing facility that a kind of greenhouse of design is used.
The utility model is achieved in that
The tooth bar transmission windowing facility that a kind of greenhouse is used, constitute by gear seam 1, tooth bar seam 2, side plate 3, fixed axis 4, spacing ring 5, position-limited wheel 6, nut 7, forms 8, power transmission shaft 9, tooth bar seam 2 is hinged by hinge barrels and forms 8, biside plate 3 is in the shaft shoulder both sides of fixed axis 4, position-limited wheel 6 has two, be positioned at the groove inboard of U type groove tooth bar, the relative position of rack and pinion is by side plate 3, spacing ring 5 and position-limited wheel 6 controls.
The greenhouse is as follows with the advantage and the good effect of tooth bar transmission windowing facility:
The utility model optimum range is wide.This mechanism can be used for plastic double-layer aerated film greenhouse, PC plastic plate greenhouse and other types roof ventilater, side window opens and closes.
The gear external toothing mode that the utility model adopts is because the deadweight pressed toward gear of tooth bar can make wheel and rack keep good engagement.
The utlity model has simple in structure, advantages such as processing and manufacturing easy, reliable transmission, maintenance easy accessibility.
This mechanism is involute gear and arc (or linear) slotted eye tooth bar external toothing transmission, and the spacing employing of gear, tooth bar is axially added fixed axis, radially added the mode of nylon roller by nylon ring by biside plate.
This device can be realized the automation control of greenhouse ventilation, and the angle that window is opened can be by the accurate location of this device.
The rack-and-pinion transmission of this window-opening mechanism is spacing by two position-limited wheels 6, and making tooth bar is the control that rubs of rolling with spacing object in motion process, can reduce the noise in the transmission process.Adopt two position-limited wheels, can make more balance of rack-and-pinion transmission.Tooth bar is being welded with hinge barrels with forms 8 hinged places, can increase intensity and the rigidity of tooth bar in the end greatly.
Description of drawings:
Fig. 1 is mechanism's schematic diagram of windowing
Fig. 2 is the main pseudosection of the utility model window-opening mechanism
Fig. 3 is the left pseudosection of the utility model window-opening mechanism
1 gear seam, 2 tooth bar seam, 3 side plates, 4 fixed axis, 5 spacing rings, 6 position-limited wheels, 7 nuts, 8 forms, 9 power transmission shafts.
Narrate embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, the tooth bar transmission windowing facility that greenhouse of the present utility model is used, constitute by gear seam 1, tooth bar seam 2, side plate 3, fixed axis 4, spacing ring 5, position-limited wheel 6, nut 7, forms 8, power transmission shaft 9, tooth bar seam 2 is hinged by hinge barrels and forms 8, biside plate 3 is in the shaft shoulder both sides of fixed axis 4, position-limited wheel 6 has two, is positioned at the groove inboard of U type groove tooth bar, and the relative position of rack and pinion is by side plate 3, spacing ring 5 and position-limited wheel 6 controls.Tooth bar seam 2 is hinged by hinge barrels and forms 8, and gear seam 1 rotating band carry-over bar seam 2 motions promote forms 8 and open or close; The relative position of rack and pinion is by side plate 3, spacing ring 5 and position-limited wheel 6 controls.Tooth bar seam 2 is made up of U type groove punching tooth bar and hinge barrels seam.
The tooth bar seam is made up of U type groove punching tooth bar and hinge barrels seam, and tooth bar is hinged by hinge barrels and forms, and this structure can increase intensity and the rigidity of tooth bar in the hinged place.Gear rotates and drives the tooth bar motion, promotes window and opens or close.Be the engaged transmission of realization rack and pinion, and the motion of tooth bar promotion window switching, the relative position of rack and pinion is limited by side plate 3, spacing ring 5 and position-limited wheel 6.
The rack-and-pinion transmission of this window-opening mechanism is spacing by two position-limited wheels 6, and making tooth bar is the control that rubs of rolling with spacing object in motion process, can reduce the noise in the transmission process.Adopt two position-limited wheels, can make more balance of rack-and-pinion transmission.Tooth bar is being welded with hinge barrels with forms 8 hinged places, can increase intensity and the rigidity of tooth bar in the end greatly.
Claims (2)
1, the tooth bar transmission windowing facility used of a kind of greenhouse, comprise nut 7, forms 8, power transmission shaft 9, it is characterized in that: also have gear seam 1, tooth bar seam 2, side plate 3, fixed axis 4, spacing ring 5, position-limited wheel 6 to constitute, tooth bar seam 2 is hinged by hinge barrels and forms 8, biside plate 3 is in the shaft shoulder both sides of fixed axis 4, position-limited wheel 6 has two, is positioned at the groove inboard of U type groove tooth bar, and the relative position of rack and pinion is by side plate 3, spacing ring 5 and position-limited wheel 6 controls.
