Angrenaj divizat, O alt\u0103 metod\u0103 const\u0103 \u00een dou\u0103 jum\u0103t\u0103\u021bi de echipament pozi\u021bionate una l\u00e2ng\u0103 alta.

Acest lucru m\u0103re\u0219te grosimea efectiv\u0103 a dintelui pentru a se asigura c\u0103 umple complet spa\u021biul dintelui ro\u021bii din\u021bate de cuplare, elimin\u00e2nd astfel jocul. \u00centr-o alt\u0103 edi\u021bie, un asamblor fixeaz\u0103 cu \u0219uruburi jum\u0103tatea rotit\u0103 la jum\u0103tatea fix\u0103 \u200b\u200bdup\u0103 asamblare.

Cea mai simpl\u0103 \u0219i mai comun\u0103 metod\u0103 de a reduce jocul \u00eentr-o pereche de ro\u021bi din\u021bate este scurtarea lungimii dintre centrele lor. Aceasta deplaseaz\u0103 ro\u021bile din\u021bate \u00eentr-o angrenare mai str\u00e2ns\u0103, cu un joc mic sau chiar zero \u00eentre din\u021bi. Elimin\u0103 rezultatul varia\u021biilor distan\u021bei intermediare, dimensiunilor din\u021bilor \u0219i excentricit\u0103\u021bilor rulmentului. Pentru a scurta distan\u021ba intermediar\u0103, fie schimba\u021bi ro\u021bile din\u021bate la un interval stabilit \u0219i bloca\u021bi-le \u00een pozi\u021bie (cu \u0219uruburi), fie solicita\u021bi una de cealalt\u0103 cu arc, astfel \u00eenc\u00e2t s\u0103 r\u0103m\u00e2n\u0103 angrenate str\u00e2ns.
Ansamblurile fixe sunt utilizate de obicei \u00een aplica\u021bii cu sarcini mari, unde reductoarele trebuie s\u0103 \u00ee\u0219i inverseze direc\u021bia de rota\u021bie (bidirec\u021bional\u0103). De\u0219i \u201efixe\u201d, acestea ar putea necesita totu\u0219i reajustare \u00een timpul utiliz\u0103rii din\u021bilor. Angrenajele conice, cilindrice, elicoidale \u0219i melcate se preteaz\u0103 la aplica\u021bii fixe. Ansamblurile cu arc, \u00eens\u0103, men\u021bin un joc zero continuu \u0219i sunt utilizate \u00een general pentru aplica\u021bii cu cuplu redus.<\/p>\n

Metodele comune de proiectare includ distan\u021b\u0103 central\u0103 scurt\u0103, angrenaje divizate cu arc, materiale de umplutur\u0103 de tip plastic, angrenaje conice, trenuri de angrenaje pre\u00eenc\u0103rcate \u0219i trenuri de angrenaje cu cale dubl\u0103.<\/p>\n

Reductoarele de precizie limiteaz\u0103 de obicei jocul la aproximativ 2 grade \u0219i, prin urmare, sunt utilizate \u00een aplica\u021bii precum instrumenta\u021bia. Dispozitivele de precizie superioar\u0103 care realizeaz\u0103 un joc aproape zero sunt utilizate \u00een aplica\u021bii precum, de exemplu, sistemele robotizate \u0219i axele dispozitivelor ma\u0219inilor.
Designul angrenajelor poate fi modificat \u00een multe feluri pentru a reduce jocul. Unele strategii modific\u0103 angrenajele la un joc stabilit al din\u021bilor \u00een timpul asambl\u0103rii ini\u021biale. Cu acest proces, jocul cre\u0219te \u00een cele din urm\u0103 din cauza uzurii, care necesit\u0103 reajustare. Alte designuri utilizeaz\u0103 arcuri pentru a sus\u021bine angrenajele la un nivel continuu de joc pe toat\u0103 durata existen\u021bei lor. Cu toate acestea, acestea sunt \u00een general limitate la aplica\u021bii cu sarcini u\u0219oare.<\/p>\n

Split gearing, another method, consists of two equipment halves positioned side-by-side. Half is fixed to a shaft while springs cause the other half to rotate somewhat. This escalates the effective tooth thickness to ensure that it totally fills the tooth space of the mating gear, thereby eliminating backlash.
