Description

Length direction becomes the open type belt driver of Y shape

Technical field

The invention belongs to mechanical equipment, particularly a kind of length direction becomes the open type belt driver of Y shape.

Background technology

In many mechanical equipments and measurement mechanism, often need to realize mobile unit and at positive and negative both direction, stretch out the driving device of load-carrying unit.Such as in modern three-dimensional storage apparatus and mechanical parking equipment, all needing has such driving device, with realize goods or vehicle in storage position/the vertical or horizontal access of the position of berthing.This type of drive mechanism form is more at present, but in some equipment, adopts existing mechanism to be always weak.For example patent of invention CN101259919B is slided adopted device, and stretching out of its multistage sliding york can be realized by rack-and-gear, chain and toothed belt transmission structure, all exists inter-stage ride comfort poor, baroque deficiency but youngster plants implementation structure; Utility model patent CN2811472Y carrying device for stereo garbage, moving structure is chain sprocket transmission, the structure that this patent provides is because chain and two sprocket wheel sprocket both sides frictions is different, and makes transmission produce larger transverse force, therefore has the low and large shortcoming of noise of driving efficiency.

Summary of the invention

Object of the present invention is exactly for the deficiency that this type of drive mechanism exists at present, proposes the open type belt driver that a kind of length direction becomes Y shape, and this device can make employing equipment realize high efficiency, quiet peace saequential transmission is moving.

The technical scheme that the present invention takes is as follows: a kind of length direction becomes the open type belt driver of Y shape, and basic structure consists of Gent flat rubber belting processed or cog belt, two flat tyre wheels or two flute profile belt wheels, one or two tension wheel, two carrier wheels, mobile station and frames.Special flat rubber belting or cog belt are open type flat rubber belting or the cog belt that becomes Y type in a kind of length, two flat tyre wheels or two parallel both sides over against being installed on gantry motion direction of flute profile belt wheel, special flat rubber belting or cog belt driving surface are walked around two belt wheels, singly with portion, pass that biobelt portion is opposing extends to single head and double end is fixed with one end of mobile station respectively, by forming messenger chain after tension wheel tensioning, in belt wheel when rotation, makes the single head of special flat rubber belting or cog belt and double end move and drive the movement of mobile station to same direction, or move through special flat rubber belting or the cog belt of mobile station make belt wheel rotation, carrier wheel by this direction when mobile station moves to different directions carries out effective rest and auxiliary tensioning to belt body, as power drive, also comprise driving actuating unit, while adopting cog belt transmission, not only can realize moving back and forth of mobile station, and can realize by rotary encoder the accurate measurement of sense of motion, speed and distance, for improving driving force and stability, the messenger chain in this device can be duplex structure, symmetry or be 180 ° of layouts.

Mobile station is the mobile unit of device, its structure is relevant with concrete application, it is the component part of its application apparatus, at least by the single head of stand, special flat rubber belting or cog belt and double end fixed mechanism and movement support device, formed, its movement support device can for support roller or other straight-line motions with support function secondary.

Frame is the load-carrying unit of device, its structure is relevant with concrete application, be the component part of its application apparatus, at least by framework, flat tyre wheel or flute profile belt wheel installation shaft bearing, tension wheel installation shaft bearing, carrier wheel installation shaft bearing, and drive the mounting base of actuating unit to form.

Guiding mechanism is realized the guiding that mobile station moves back and forth, and can be guide wheel guide rail or other straight-line motions secondary; Its guide wheel is connected with frame with mobile station respectively with relative motion two parts of guide rail or straight-line motion pair; The movement support device of guiding mechanism and mobile station can be same mechanism.

Drive actuating unit at least by retarder and motor, to be formed, as preferred motor, adopt the servo or alternating-current variable frequency motor of band brake.

The preferred Timing Belt of its special tooth-like belt during further, as the driving device of measuring equipment.

As power drive, realizing like this mobile station both direction moves back and forth: motor drives active flat tyre wheel or flute profile belt wheel to rotate by retarder, single head and double end that the active flat tyre wheel of rotation or flute profile belt wheel drive special flat rubber belting or cog belt are moved to same direction, thereby tethered sliding platform is along reference plane or guide rail or straight-line motion secondary motion, the rotating of motor, realizes the motion to different directions; As measuring driving device, be to realize like this mobile station both direction kinematic velocity and range observation back and forth: when mobile station moves back and forth, drive Timing Belt single head and double end to move in the same way, the Timing Belt of motion drives synchronous pulley to rotate, and the synchronous pulley of rotation makes the rotary encoder output mobile platform sense of motion, speed and the range observation information that are connected with its main shaft.

It is a kind of driving device moving back and forth of realizing that length direction disclosed by the invention becomes the open type belt driver of Y shape, can be integrated into well and need left and right, front and back or the neutralization of both direction moves back and forth up and down machinery and equipment for there being the measuring equipment of this driving device, particularly can be directly used in three-dimensional storage apparatus carrying mechanism and mechanical three-dimensional parking device connecting mechanism.
