Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of Multi-functional transmission mechanism experiment porch comprises motor 1, slippage gear train, Geneva mechanism, synchronizing wheel mechanism and sensor, motor 1 connects one end of slippage gear train, the other end of slippage gear train connects synchronizing wheel mechanism, synchronizing wheel mechanism link slot wheel mechanism, sensor is located on slippage gear train and Geneva mechanism respectively.Sensor adopts speed pickup.Slippage gear train and Geneva mechanism are all by supporting seat 12 fixed support.
Wherein, slippage gear train comprises the first transmission shaft 2, second driving shaft 3, feather key 4, shifting slide gear 5, duplicate gear 6 and spur gear 7, the end of the first transmission shaft 2 connects motor 1, feather key 4 is located on the first transmission shaft 2, shifting slide gear 5 is located on feather key 4 by jump ring, first gear and the second gear are individually fixed on second driving shaft 3, shifting slide gear 5 and the first gear or the second gears meshing, synchronizing wheel mechanism connects the end of second driving shaft 3, and sensor is located on the first transmission shaft 2 and second driving shaft 3 respectively.Slippage gear train by motor 1 drived control, and realizes speed change by feather key 4 connection and gears meshing.During operation, the position of engaging on feather key 4 by manually arranging shifting slide gear 5 with jump ring changes the size of gear ratio, thus realizes speed change.
Geneva mechanism comprise the 3rd transmission shaft 8, rotating disk 9 and sheave the 10, three transmission shaft 8 one end connect synchronizing wheel mechanism, the other end connect rotating disk 9, rotating disk 9 is provided with the straight pin be rotatably assorted with sheave 10, and sensor is located on the 3rd transmission shaft 8 and sheave 10 respectively.Geneva mechanism is by rotating rotating disk 9, and make straight pin proceed to the radial slot of sheave 10, and then make sheave 10 turn over 45 °, after straight pin produces radial slot, sheave 10 stops operating.Rotating disk 9 circles, sheave 10 complete once turning stop transport dynamic.Geneva mechanism structure is simple, and easily process, corner is accurate.
The belt that synchronizing wheel mechanism comprises two belt pulleys 11 and is set on belt pulley 11, two belt pulleys 11 are located on second driving shaft 3 and the 3rd transmission shaft 8 respectively.
Principle of work:
Shifting slide gear 5 realizes slippage by feather key 4, duplicate gear 6 and spur gear 7 are on same transmission shaft, and shifting slide gear 5 engages with duplicate gear 6 or spur gear 7, and motor 1 drived control first transmission shaft 2 operates, shifting slide gear 5 rotates, and drives second driving shaft 3 to rotate simultaneously.Because duplicate gear 6 is different with the diameter of spur gear 7, so when shifting slide gear 5 moves to diverse location, ratio of gear is in different size, transmission speed changes thereupon, thus realizes the motion of speed change.Again by belt pulley 11 transmission, belt pulley 11 degree of tightness also can be surveyed to whole motion 3-dimensional image.The 3rd transmission shaft 8 that belt pulley 11 output terminal connects, drives rotating disk 9 to move, and when the straight pin on rotating disk 9 moves to sheave 10, drives sheave 10 to rotate 45 °, observes the speed of movement velocity by the principle of vitascope intuitively.Supporting seat 12 is effects of back shaft, prevents vibration.
The utility model by increasing several groups of different drive disk assemblies on experiment porch, by the different mechanical transmission structure of sensor record to the change of the size of output speed size, power.Changed the size of gear ratio by shifting slide gear 5, change transmission speed, by the transmission of synchronizing wheel, finally compare speed that sheave 10 exports, speed etc. that sheave 10 rotates, and research affects the reason of rotating speed size.
