Abstract
The utility model relates to a transmission mechanism of an MIT paper folding endurance tester. In the transmission mechanism assembly processing of a conventional MIT paper folding endurance tester, assembly parts are more, the assembly debugging period is too long, the production efficiency is affected, and the operation noise is too high of the whole assembled machine. The transmission mechanism comprises a base, a driving motor is installed on the base, a driving wheel is installed on a shaft extension of the driving motor, and on the base, a gearwheel and a pinion are positioned on the side edge of the driving wheel and are meshed with each other, connecting pins are arranged on the gearwheel and the driving wheel, the connecting pins on the gearwheel are connected with the connecting pins on the pinion by joint bearings, and a chuck base is arranged on the outer end of the pinion. According to the transmission mechanism, the processing period of mechanical parts is shortened effectively, a purchased part is adopted for replacing a self-made component, the cost is lowered, the assembling and debugging period is shortened, the one-time percent of pass of finished products is improved, and the noise is low.
Description
Technical field
The utility model relates to a kind of driving mechanism of MIT paper folding endurance testing instrument.
Background technique
The drive motor of the driving mechanism of existing MIT paper folding endurance testing instrument is fixing separately by the motor frame, the crankwheel of packing on the shaft extension of motor, and the crankshaft of on this crankwheel, packing into.In the motor rotation process, drive pushing-pulling-plate (pushing-pulling-plate is by last guide card, following guide card, goes up spacer block, and a plurality of parts such as following spacer block connect the support of fixing back) by crankwheel and crankshaft and carry out straight reciprocating motion.Pushing-pulling-plate connects tooth bar, and tooth bar engaging tooth axle drives base of the carrier head and realizes 135 ° ± 2 ° back and forth folding.Rack shaft is by connecting nail, roller stand, spacer ring, and a plurality of parts such as spacer are fixed and supported.Original mechanism adopts eccentric wheel to add the reciprocal folding movement that slide block gear teeth bar structure realizes the folding endurance lower chuck, and angle is 135 ° ± 2 °.This structure total has 32 kinds of (53) machined piece to be formed, and drive path is long, and machined part is various, and processing technology requires high.The repair part is more in the assembly process, and the assembling and setting excessive cycle influences manufacturing efficiency, and the running noises of assembling back complete machine is excessive.
The model utility content
The utility model provides a kind of driving mechanism of MIT paper folding endurance testing instrument to the defective that existing technology exists, and effectively solves the difficult problem of processing technology, improves the up-to-standard rate of workpiece, is convenient to assembling and debugging, enhances productivity, and reduces noise.
For this reason; The utility model is taked following technological scheme: a kind of driving mechanism of MIT paper folding endurance testing instrument comprises base, installing drive motor on the base; One driving wheel is installed on the shaft extension of said drive motor; The side that is positioned at driving wheel on the described base is gearwheel and small gear successively, and gearwheel and small gear are meshing with each other, and are equipped with connecting pin on described gearwheel and the driving wheel; Connecting pin on the said gearwheel links to each other through joint shaft bearing with connecting pin on the small gear, and the outer end of said small gear is provided with base of the carrier head.
Described gearwheel is fixed on the base through bearing support, bearing and minor axis, and described small gear is fixed on the base through bearing support, bearing and major axis.
The structure of the utility model amounts to 12 kinds of (15) machined piece and cover (two a) joint shaft bearing is formed jointly, has effectively realized base of the carrier head back and forth folding at 135 ° ± 2 °.Also have the following advantages: component are few, effectively shorten the process-cycle of mechanical parts, also can adopt outsourcing piece to replace self-made components, reduce cost, and shorten assembling and debugging cycle, also improved the finished product first-time qualification rate, and noise is low.
Figure of description
Fig. 1 is the structural representation of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
The driving mechanism of MIT paper folding endurance testing instrument as shown in Figure 1; Comprise base 3, installing drive motor 13 on the base 3 is installed a driving wheel 11 on the shaft extension of drive motor 13; The side that is positioned at driving wheel 11 on the base 3 is gearwheel 8 and small gear 2 successively; Gearwheel 8 is meshing with each other with small gear 2, is equipped with connecting pin 7 on gearwheel 8 and the driving wheel 11, and the connecting pin 7 on the gearwheel 8 links to each other through joint shaft bearing 14 with connecting pin 7 on the small gear 2; Joint shaft bearing 14 comprises double threaded screw 9 and left-handed nut 10, and the outer end of small gear 2 is provided with base of the carrier head 1.Gearwheel 8 is fixed on the base 3 through bearing support 4, bearing, spacer 6 and minor axis 12, and small gear 2 is fixed on the base 3 through bearing support 4, bearing, spacer 6 and major axis 5.
What need particularly point out is; The mode of the foregoing description only limits to describe embodiment; But the utility model is confined to aforesaid way incessantly; And those skilled in the art can modify in the scope that does not break away from the utility model in view of the above easily, so the scope of the utility model should comprise the principle that the utility model discloses and the maximum magnitude of new feature.
