▁from ▁the ▁load ▁on ▁the ▁sun ▁g ear ▁to ▁the ▁ann ulus ▁and ▁thereby ▁st alling ▁the ▁output ▁until ▁tor que ▁is ▁reduced ▁to ▁an ▁amount ▁where ▁the ▁ball ▁det ents ▁can ▁lock ▁the ▁ann ulus ▁again . ▁This ▁system ▁equally ▁limits ▁tor que ▁in ▁both ▁directions ▁of ▁rotation ▁and ▁also ▁works ▁with ▁the ▁sun ▁g ear ▁as ▁the ▁input . ▁The ▁compression ▁of ▁the ▁ball ▁det ents ▁( and ▁therefore ▁the ▁amount ▁of ▁tor que ▁at ▁which ▁the ▁lim iter ▁is ▁util ized ) ▁is ▁typically ▁adjust ed ▁by ▁means ▁of ▁a ▁rot ating ▁col lar ▁accessible ▁to ▁the ▁user ▁which ▁is ▁indexed ▁and ▁held ▁in ▁place ▁with ▁its ▁own ▁separate ▁ball ▁det ents . ▁ ▁P aw l ▁and ▁spring ▁This ▁mechanical ▁type ▁uses ▁a ▁spring ▁to ▁hold ▁a ▁drive ▁p aw l ▁against ▁a ▁not ch ▁in ▁the ▁rot or . ▁It ▁may ▁feature ▁automatic ▁or ▁manual ▁reset . ▁A ▁compression ▁adjust ment ▁on ▁the ▁spring ▁determ ines ▁the ▁tor que ▁limit . ▁ ▁Tor que ▁limit ing ▁types ▁Tor que ▁limit ing ▁types ▁will ▁limit ▁the ▁tor que ▁by ▁sli pping ▁( i . e . ▁letting ▁the ▁drive ▁sh aft ▁run ▁faster ▁than ▁the ▁driven ▁sh aft .) ▁Ex cess ▁power ▁is ▁diss ip ated ▁as ▁heat . ▁They ▁don ' t ▁need ▁to ▁be ▁reset . ▁ ▁Fr iction ▁plate ▁This ▁type ▁is ▁similar ▁to ▁a ▁fr iction ▁plate ▁cl utch . ▁Over - tor que ▁will ▁cause ▁the ▁pl ates ▁to ▁s lip . ▁ ▁A
