Detailed description of the invention
Hereinafter, embodiments of the present invention are described.Fig. 1 is the sectional view of the torque limiter of embodiments of the present invention.
Inner ring component is formed by inner ring member body 11a and inner ring component extension 11b.By arranging inner ring component extension 11b, and
Extend cycle component 13 accordingly with inner ring component extension 11b, thus torque limiter itself is formed longer.
Inner ring member body 11a is wound with helical spring 12, utilizes outer surface and the spiral of inner ring member body 11a
Friction between spring 12 produces moment of torsion.As helical spring 12, such as, use metal spring.It addition, inner ring member body 11a
Formed by the special resin material containing a large amount of carbon fibers, such as, formed by PPS (polyphenylene sulfide).Due to inner ring component master
Body 11a utilize and as between the helical spring 12 of metal friction produce moment of torsion, therefore, this be in order to improve as with spiral
The patience of inner ring member body 11a of the friction portion of spring 12 phase mutual friction.
On the other hand, inner ring component extension 11b is formed by ordinary resin material.This is because, inner ring component extension
11b does not utilizes the friction between helical spring 12 to produce moment of torsion, therefore, does not has the friction part with helical spring 12 phase mutual friction
Divide without improving patience.It addition, inner ring component extension 11b is mechanically linked in inner ring member body 11a.Such as, by interior
One side end of circle component extension 11b is formed as D-shaped cutting portion, is inserted into by a side end of inner ring component extension 11b

Therefore, there is no need to additionally prepare axle.
It is now assumed that inner ring member body 11a is applied with load torque.It is below torque limit value at load torque
Time, utilize the frictional force between the inner surface of helical spring 12 and inner ring member body 11a to make inner ring member body 11a and outer ring
Component 13 is integrally forming and rotates, and transmits moment of torsion to cycle component 13.On the other hand, torque limit value has been exceeded at load torque
Time, inner ring member body 11a dallies and cuts off the moment of torsion to cycle component 13 transmission.On the contrary, cycle component 13 is applied with
The situation of load torque is also same, when load torque is below torque limit value, transmits moment of torsion to cycle component 13,
When load torque has exceeded torque limit value, cut off the moment of torsion to cycle component 13 transmission.
So, inner ring component is divided into two parts, is set to apply special resin by the part rubbed with helical spring 12
Inner ring member body 11a of material, is set to apply the inner ring component of cheap ordinary resin material by part in addition
