Abstract
The utility model discloses a bearing drive mechanism for a sliding-plug door. The bearing drive mechanism comprises a cylindrical spline which is fixed axially, a door frame carrying component, a linear guide rail, a slider and door leaf component. By the aid of a double gear spline transmission mechanism, the door leaf component can be further shifted along the same direction relative to the door frame carrying component, and accordingly openness stroke of door leaves is increased under limited mechanism length. The bearing drive mechanism for the sliding-plug door is simple in structure and light enough to mount.
Description
Technical field
The utility model belongs to inter-city rail transit door device technical field, relates in particular to the carrying drive unit in the plug sliding door system.
Background technology
City rail plug sliding door door leaf aperture is generally 1300mm and two kinds of 1400mm, the car body doorway openings 1590mm and the 1700mm of correspondence.So-called short mechanism is meant that the length of carrying driving mechanism is no more than the car body doorway openings, for the mechanism that adopts single guide pillar slide cartridge structure; Because the length of two groups of slide cartridges adds the stroke and the guide pillar support member of door leaf, its total length has surpassed more than the car body doorway openings 200mm, if adopt two guide pillar structures; Though can solve length issue, complex structure, weight is overweight; Oversized on other two directions has exceeded the spatial accommodation of existing car body.
Summary of the invention
Goal of the invention: to the problem and shortage of above-mentioned existing existence, the purpose of the utility model provides a kind of lightweight sliding plug door bearing driving mechanism simple in structure, and can be at the aperture stroke that increases door leaf.
Technical scheme: for realizing the foregoing invention purpose; The utility model adopts following technical scheme: a kind of sliding plug door bearing driving mechanism; Comprise axial restraint the cylinder tooth bar, take door frame assembly, line slideway, slide block and door leaf assembly; Wherein: the said door frame assembly of taking comprises gearcase, gear wheel and pinion, and said gear wheel and pinion are in-line gears, and is installed on the said gearcase; Said line slideway is fixedly connected with this gearcase; Said door leaf assembly is made up of the door leaf that tooth bar is installed, and this tooth bar is connected with slide block, and said slide block and line slideway match simultaneously, can move along line slideway; The said gear wheel of taking on the door frame assembly is set up into transmission mechanism jointly with the cylinder rack tooth, makes to take the door frame assembly and rotate driving gear wheel when the cylinder tooth bar moves horizontally; Tooth bar on the said door leaf assembly is set up into transmission mechanism jointly with pinion gear teeth, and the door leaf assembly is moved horizontally along line slideway with respect to taking the door frame assembly under the transmission of pinion.
When machine operation, drive and take the door frame assembly and move horizontally along guide pillar, the cylinder tooth bar of axial restraint makes the gear wheel meshing with it roll along this cylinder tooth bar; Meshing with pinion simultaneously tooth bar equidirectional moving under the transmission of pinion; Because this tooth bar is connected with door leaf with slide block simultaneously; Therefore door leaf, tooth bar and slide block become an integral body; The door frame assembly is further equidirectionally to be moved along line slideway this integral body with respect to taking under the transmission of pinion, thereby has increased the sliding stroke of door leaf.
Further improvement to such scheme; Also comprise guide pillar, slide cartridge and hinges; Wherein said guide pillar level is installed in institutional framework, and hinged through hinges and cylinder tooth bar formation, said slide cartridge with take the door frame assembly and be connected; And be enclosed within on the guide pillar, thereby can realize making the cylinder tooth bar, take the door frame assembly and the door leaf assembly can rotate around guide pillar together.
As preferably; When the aperture of door leaf required to 1300mm (simple gate 650mm), the pitch radius of said gear wheel was 60mm, and the pitch radius of said pinion is 36.5mm; Make that taking the door frame assembly is 427mm in the displacement of cylinder tooth bar; Door leaf is 223mm with respect to taking the further displacement of door frame, thereby only makes and under mechanism's length of 427mm, just to make door leaf have the sliding stroke of 650mm with respect to car body.
Beneficial effect: compared with prior art; The utlity model has following advantage: thus make door leaf can further slide and be implemented in the aperture stroke that limited mechanism's length increases door leaf through bidentate wheel rack gear with respect to taking the door frame assembly; And simple in structure, weight relatively gentlier can satisfy installation fully.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
Shown in Fig. 1～3; A kind of sliding plug door bearing driving mechanism, the aperture of this door leaf 7 require to be 1300mm (simple gate 650mm), comprise axial restraint cylinder tooth bar 1, take door frame assembly, line slideway 5, slide block and door leaf assembly; Wherein take the door frame assembly and be used to connect line slideway 5, slide cartridge 9 and door leaf 7; This is taken the door frame assembly and is made up of gearcase 2, gear wheel 3 and pinion 4, and the pitch radius of said gear wheel 3 is 60mm, and the pitch radius of pinion 4 is 36.5mm; And gear wheel 3 is in-line gears with pinion 4, simultaneously line slideway 5 is fixed on the gearcase 2; And the door leaf assembly is made up of the door leaf that is fixed with tooth bar 67, is connected with slide block with hour rack 6, thereby makes the door leaf assembly to move along line slideway 5 along with slide block; Gear wheel 3 and cylinder tooth bar 1 meshing composition transmission mechanism during installation make and take the door frame assembly and when cylinder tooth bar 1 moves horizontally, drive gear wheel 3 and rotate; The mechanism and the tooth bar 6 on the door leaf assembly and pinion 4 meshing compositions are passed on Gong makes the door leaf 7 can the door frame assembly is equidirectional further to move horizontally along line slideway 5 with respect to taking under the transmission of pinion 4.On institutional framework, go back installation one guide pillar 8 of level in addition; A sheathed slide cartridge 9 on this guide pillar 8; This slide cartridge 9 is connected with the gearcase of taking the door frame assembly 2 simultaneously; Constitute through hinges 10 and this guide pillar 8 simultaneously in cylinder tooth bar 1 end hinged, thereby make the door leaf assembly with take the door frame assembly and can with cylinder tooth bar 1 when guide pillar 8 rotates, can carry out the action of switch door along guide pillar 8 again.
When machine operation, drive slide cartridge and take the door frame assembly and move horizontally 427mm along guide pillar; The cylinder tooth bar of axial restraint makes the gear wheel meshing with it 3 roll along this cylinder tooth bar 1; Simultaneously meshing tooth bar 6 equidirectional moving under the transmission of pinion 4 with pinion 4; Because this tooth bar 6 is connected with door leaf 7 with slide block, so door leaf 7, tooth bar 6 and slide block become an integral body, and this integral body is further equidirectional along the mobile again 223mm of line slideway 5 with respect to taking the door frame assembly under the transmission of pinion 4; Thereby increased the sliding stroke of door leaf 7, and finally realized the aperture of simple gate 600mm.Therefore with respect to two guide pillar 8 structures, the utility model simple in structure, in light weight.
