Specific embodiment is as follows:
As shown in Fig. 2, when the critical-temperature of heat responsive deformation connecting rod 4 is high temperature (such as 120 °), heat responsive deformation at normal temperature
Connecting rod 4 is solid-state, and spring 5 is initially compressive state, and it is at this time clutched state that axis tile piece 6, which is compacted, which embraces output shaft 7,
It is fricton-tight, and initially without centrifugal force.Power is inputted by input gear 1, is driven, is passed through by the transmission gear ring 2 engaged
Solid heat responsive deformation connecting rod 4, axis tile piece 6 drive output shaft 7 to rotate.
When after a period of work, temperature is increased to the critical-temperature of heat responsive deformation connecting rod 4 in clutch, heat responsive deformation connects
Bar 4 begins to change into soft viscous pasty state, reduces on axis tile piece 6 to the pressing force in axle center, and axis tile piece 6 and output shaft 7 occur to slide relatively
Dynamic or separation (as shown in figure 3, clutch is in discrete state), output torque reduce even without output, play high temperature protection work
With.
When input is abnormal ultrahigh rotating speed occurs, if frictional heating makes temperature in clutch be increased to heat responsive deformation connecting rod 4
Critical-temperature, then heat responsive deformation connecting rod 4 becomes soft viscous pasty state, and axis tile piece 6 and output shaft 7 occur opposite slide and make output shaft
7 revolving speed torques are unlikely to very high and damage the equipment to connect with output shaft 7.
When temperature does not reach the critical-temperature of heat responsive deformation connecting rod 4 in clutch, it is very big that high revolving speed generates axis tile piece 6
Centrifugal force reasonably selects the parameter of heat responsive deformation connecting rod 4 and spring 5, so that centrifugal force is greater than squeezing for spring force and thermo-sensitive material
The sum of pressure, axis tile piece 6 is separated with output shaft 7 at this time, and clutch is in discrete state.
In addition, the parameters such as the critical-temperature characteristic of heat responsive deformation connecting rod, spring strength is reasonably selected to may make clutch
Original state is engagement or separation.
To sum up, the clutch of cooling using heat responsive deformation connecting rod deformation force at different temperatures and spring force and from
The sum of mental and physical efforts three come determine clutch separation with engage, the variation of revolving speed, temperature can be adapted to automatically, in ultrahigh rotating speed, high temperature
It can be automatically separated and shield under degree, not need additional sensor and electronic circuit, without permanent magnet.
