Description
Technical field
The present invention relates to the employed spring torque limiter of office equipment of a kind of printer, duplicating machine etc., particularly can prevent the interference of coil spring end and interior wheel.
Background technique
Always be the spring torque limiter that is used for office equipment etc. that everybody knew well, as shown in Figure 7, by being constituted: outer ring element 41 with lower member, it is inner and can be supported on interior wheel 43 in the hub portion 42 of an end with the relative rotation to insert it, be installed in this coil spring 44 of the outer diametric plane of wheel 43 with the use level of regulation, the lid member 49 of the interior wheel 43 that the gap between the outer diametric plane of sealing and the chimeric interior wheel 43 that is fixed on its aperture surface and support rotate freely in the other end of ring element 41 above-mentioned outside.Above-mentioned coil spring 44 has large-diameter portion 44a and minor diameter part 44b, its minor diameter part 44b, with the use level of regulation tightly be attached to above-mentioned in wheel 43 outer diametric plane.Be provided with crooked vertically hook 45 in the end of this minor diameter part 44b, make its hub portion that is fastened on above-mentioned outer ring element 41 42.Also have, also be provided with crooked vertically hook 46 in the end of large-diameter portion 44a, it is sticked in covers member 49 (with reference to patent documentation 1).
Above-mentioned torque limiter 40 by the relative rotation of interior wheel 43 and outer ring element 41, watches coil spring 44 to be rotated along its coil direction from hook 45 1 sides, then in minor diameter part 44b, produce the hole enlargement effect, make a certain size torque, that is, the regulation torque value produces.When its edge was rotated with above-mentioned direction opposite direction, at minor diameter part 44b, because the undergauge effect generates, interior wheel 43 lockings were so can not realize its function as torque limiter at this moment.That is the effect that, only has unidirectional torque limiter.
About the size adjustment of afore mentioned rules torque value, use the instrument of regulation to make cover member 49 to be rotated at fixing outer ring element 41 from the outside, through the large-diameter portion 44a of coil spring 44, the use level of minor diameter part changes, thus, the torque value that adjustment is stipulated.
Above-mentioned torque limiter 40 for example, is connected for using by the end with the intake roller 47 (with reference to Fig. 7, Fig. 8) of the end of hub portion 42 sides of outer ring element 41 and office equipment etc.The load torque that acts on intake roller 47 is when the regulation torque value of torque limiter 40 is above, the outer ring element 41 of torque limiter 40 is rotated from load side (paper feed roller 48 shown in Figure 8) that (reference arrow a) is sent paper 50, but the overlapping transmission of paper 50 takes place, then owing to the decline along with overlapping transmission friction, load torque is compared with the regulation torque value of torque limiter 40 and is lightened.Therefore, outer ring element 41 and intake roller 47 are rotated (with reference to the dash-dot arrows b of Fig. 8) by coil spring 44 to contrary direction from interior wheel 43 sides that are installed in axle 51, will push back with the paper 50 that intake roller 47 joins, and overlapping transmission is resolved.
