Folding house roof vertical adjustment bearing
Technical field
The utility model relates to the art field that building structure combines with Mechatronic Systems, and is special relevant with folding house roof vertical adjustment bearing.
Background technology
For the folding house roof building, in movable roof construction and installation, mobile running, owing to reasons such as dead load, wind load, snow load, temperature, structural internal forces, the movable roof bearing need adapt to the distortion of track or structure.In folding house roof vertical adjustment device in the past; The hydraulic lifts that adopt more, owing to the long-time semiclosed work of open roof lid mechanical system, hydraulic oil pollutes easily, goes bad; Hydraulic system is leaked easily, causes the maintenance cost of system higher like this, the reliability service time is shorter.
In order to address the above problem, the inventor designs folding house roof vertical adjustment bearing, and this case produces thus.
The utility model content
Technical problem to be solved by this invention is; Overcome the defective that prior art exists; Adopt machine driving and the technical scheme that automatically controlled detection system combines, a kind of vertical adjusting device simple in structure, safe and reliable, easy to maintenance is provided, satisfy movable roof and install and course of work requirement.
In order to achieve the above object, the utility model is realized through following technical scheme:
Folding house roof vertical adjustment bearing comprises motor, travelling gear, screw shaft, nut, flange; Motor output shaft power drives screw shaft by travelling gear and rotates, and moves up and down on nut spiral and the screw shaft, moves jointly with it on flange solid welding and the nut.
Described travelling gear comprise the pinion that connects motor, with gear wheel, gear wheel endoporus and the screw shaft key connecting of pinion.
The inner cavity chamber that described travelling gear and screw shaft are arranged in lower box and upper box formation offers cylindrical hole on the upper box, flange stretches in the cylindrical hole and welds with nut.
Described flange comprises flange surface and extended flange cylinder from the flange surface; Flange stretches out the cylindrical hole of upper box; Flange cylinder bottom is connected with nut, and the lateral surface of flange cylinder offers vertical groove, with the cylindrical hole place feather key is set and forms radial location.
Described cylindrical hole outer face is fixed with cover plate.
Described screw shaft bottom thrust bearing connects; The centre of screw shaft is with deep groove ball bearing, and the axle sleeve location through being connected with upper box.
Described flange is installed the ultrasonic displacement sensor.
Described motor is for exchanging reducing motor.
After adopting such scheme, the utlity model has many beneficial effects:
The utility model can link with the support chassis of folding house roof, and flange can link with movable roof, and large and small gear is meshing with each other and drives by exchanging reducing motor, and gear wheel drives vertical screw shaft and rotates, thereby drive nut and flange move up and down.Adopt nut and vertical flange to move up and down in the utility model, make adjusting device not only can bear bigger vertical load, can also bear certain lateral load.Through guaranteeing the quality of fit of upper box cylindrical hole and flange, can prevent in nut and the screw drive process, because eccentric " killing " phenomenon that takes place.In static duty, the utility model screw thread transmission system has auto-lock function.
The utility model is reformed traditional hydraulic way, realizes the folding house roof vertical adjustment through mechanical rotation, for the technical barrier in this field has proposed a kind of brand-new technical solution means.
Description of drawings
Fig. 1 is the generalized section of the utility model preferred embodiment;
Fig. 2 is the side view of the utility model preferred embodiment.
The specific embodiment
In conjunction with accompanying drawing, preferred embodiment explains further details to the utility model.
Like Fig. 1, shown in 2, the parts that are mainly concerned with in the utility model are: exchange reducing motor 1, flange 2, cover plate 3, lower box 4, screw shaft 5, axle sleeve 6, upper box 7, nut 8, deep groove ball bearing 9, gear wheel 10, thrust bearing 11, pinion 12, feather key 13, ultrasonic displacement sensor 14.
By exchanging the soffit that reducing motor 1 is installed on lower box 4, exchange reducing motor 1 output shaft and connect, gear wheel 10 and pinion 12 engagements with pinion 12.Lower box 4 is connected with upper box 7, and pinion 12, gear wheel 10, screw shaft 5 all are arranged in lower box 4 and the upper box 7 inner inner cavity chamber 15 that form.
The endoporus of gear wheel 10 and screw shaft 5 key connecting are transmitted circumferential torque, and gear wheel 10 rotates screw shaft 5 work that drive.Bottom at screw shaft 5 connects with thrust bearing 11, bears screw shaft 5 vertical loads.Cooperate with deep groove ball bearing 9 in the middle of the screw shaft 5, the axle sleeve of fixing with upper box 76 is housed on the surface of deep groove ball bearing 9 simultaneously, position, guarantee screw shaft 5 installation concentricity requirement.Shape and size according to screw shaft 5 on upper box 7 are provided with a cylindrical hole 16.
Flange 2 comprises a flange surface 21 and flange cylinder 22, and flange cylinder 22 stretches out from flange surface 21 belows and forms, and stretches in the cylindrical hole 16, carries out solid welding with nut 8, and flange surface 21 reveals to be put outside cylindrical hole 16.
In order to ensure the radial location of flange 2, axially offer groove 23 at the lateral surface of flange cylinder 22.One feather key 13 is set at the outer end opening place of cylindrical hole 16 simultaneously inserts in the groove 23, realize the radial location of flange, guarantee that flange can arbitrarily relative circumferential backlash.Assemble a cover plate 3 again in the outer face of cylindrical hole 16, cover feather key 13, guarantee that the port of cylindrical hole 16 is smooth.
Ultrasonic displacement sensor 14 is connected on the flange cylinder 22, is positioned at flange surface 21 soffits, can detect flange 2 vertical displacements in real time.
During work; Flange 2 links with movable roof to be moved, and lower box 4 upper boxes 7 link with supporting chassis, exchange reducing motor 1 driving pinion 12; Pinion 12 drives gear wheel 10; Gear wheel 10 drive screw axles 5 rotate, thereby realize that nut 8 and flange 2 move up and down, and realize the vertical adjustment of 2 pairs of movable roofs of flange.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
