Background technique
Belt transmission is the kind of drive conventional in mechanical transmission, be generally that driving wheel is connected to follower by belt, thereby power is delivered to follower from driving wheel, and in the process of motion, the centre distance between principal and subordinate wheel remains unchanged.At some special occasions, for example, on cigarette production line, need to use in movement process main, the vicissitudinous belt transmission of centre distance between follower, this type of belt transmission, because center distance of belt wheel changes, the tensioning of belt also should be done synchronous variation, but in practical structures, the length of belt is changeless, conventionally adopt Idle wheel adapts to center distance of belt wheel variation by the variation of adjusting belt tension is set, but, the setting of Idle wheel is all to adopt fixed mode, if it is uncertain that the centre distance of belt pulley changes, fixing Idle wheel cannot play the effect of real-time tightening belt.
Model utility content
The adjusting inconvenience existing for existing drivign belt Idle wheel, the defect that in the time of can not adapting in real time center distance of belt wheel variation, drivign belt tensioning changes, the utility model provides a kind of tensioning mechanism for the drivign belt of Variable Centre Distance, can be close in real time drivign belt, guarantee the best tensioning state of drivign belt moment in transmission.
The utility model adopts following technological scheme to realize: a kind of tensioning mechanism of Variable Centre Distance drivign belt, comprise belt pressure wheel 4 and pinch roller support 5, described pinch roller support 5 one end are hingedly fixed in frame 8 by demountable structure, the other end connects described belt pressure wheel 4, described belt pressure wheel 4 contacts with the belt 2 on follower 1 with installing around at driving wheel 3, regulates the tensioning of belt 2; Also comprise the spring 6 that an adjusting pinch roller support swings, described spring 6 is arranged in a crossed manner with pinch roller support 5, and its one end connects the middle part of pinch roller support 5, and the other end is fixed.
Described spring 6 is fixed in frame 8 by demountable structure.
Described spring 6 is connected in frame 8 by spring bracket 7, and described spring bracket 7 is fixed in frame 8 by screw bolt and nut.
Described pinch roller support 5 one end are installed with sleeve 12 and are fixed in frame 8 by bearing pin 10 and nut, bearing 11 is set between described sleeve 12 and bearing pin 10 and realizes the swing of pinch roller support.
Described pinch roller support 5 is provided with the hole 9 of a row for linking springs, and described spring 6 is connected with described hole 9 adjusting that realizes spring force size by hook.
Adopt such scheme, the utlity model has following beneficial effect.
When 1, the driving wheel of belt gear and the centre distance of follower constantly change, belt pressure wheel is pressed on all the time on belt under the stretching action of spring, realizes the tensioning of belt.
2, simple in structure, install easy to adjust, wide accommodation.The amount of parts of composition mechanism is few, the processing of each part, assembling, easy maintenance.Pinch roller support and spring can carry out by demountable structure the adjustment of position, be suitable for the belt gear under various different conditions of manufacture is installed.
3, cost is low, and reliability is strong.Because structural design is simple, therefore the cost of a whole set of tensioning mechanism is not high, with respect to other similar tensioning mechanisms, has good Economy.By selecting the spring of different qualities or the position in change spring hole on pinch roller support, can to belt tension size, regulate easily, guaranteed bel-drivenn stability.
In sum, the utlity model has simple in structurely, install easy to adjustly, the feature such as cost is low, and reliability is strong, applied widely, can be widely used in the belt tension control of Variable Centre Distance belt drive system.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
