Ciorcal Sliabháin Ríomhaireachta: Céard é?

Cén é an Slip Ring?

Is eochairleictreacht é an slip ring atá á úsáid chun córas staidéarach a nasc le córas rothlóideach. Úsáidtear é i réimsí ina bhfuil rothlú ag teastáil chun fórsa nó saincheiltí leictreonacha a thraansmitéir.

Tugtar freisin ar an slip ring nasc leictreonach rothlóideach, nasc leictreonach rothlóideach, nó swivels leictreonacha. Úsáidtear é i go leor máistir leictreonacha chun feidhmíocht meicniúil a fheabhsú agus an obair a shimpliú.

Má tá ríomhaire ag rothlú le líon réimsí sainiúil. B'fhéidir a bheith in ann cabhlach fórsa le fad leor a úsáid. Ach is scéim chomhshinsearach í seo. Agus is amhlaidh nach féidir é a dhéanamh má tá comhcheilgí ag rothlú de bharr tréimhse. Níl an t-ábhar seo praiticiúil nó iontaofa do chinntí mar seo.

Cén chaoi a oibríonn an Slip Ring?

Consóidtear na slip rings as dhá chumhacht phríomha; an fán meicile agus an dearcadh bruach. I gcomhréir lena chuid úsáid agus lena dhuineas, cinneadh a dhéantar ar líon na fáiní agus na ndeirceanna.

Déantar na deirceanna as grafait nó airgead brónach. Is tionchar saoire é an grafait ach tá maighnéadas maith agus saol níos faide ag an airgead brónach.

I gcomhréir leis an RPM (rotations per minute), cuireann deirceanna fáiní rothlóideacha, nó fáiní rothlóideacha le deirceanna staidéara. Sa dá chumhacht seo, coimeádaíonn na deirceanna contacht leis an fán trí bhriathar ó na sprionge.

Ginearálta, cuireann fáiní ar an rotor agus tá sé ag rothlú. Agus tá na deirceanna staidéara agus cuireann ar an teacht deirceanna.

Déantar na fáiní as meicile cosanta cosúil le brass agus silver. Tá sé cuireann ar shaft ach cosanta le lár shaft. Tá na fáiní cosanta óna chéile le nylon nó plastic.

Agus na fáiní ag rothlú, is é an siúl reatha a chuirtear trí na deirceanna. Mar sin, déanann sé nasc leanúnach idir na fáiní (córas rothlóideach) agus na deirceanna (córas staidéarach).

Slip ring vs Commutator

Úsáidtear an slip ring agus an commutator chun nasc a chothú idir an córas rothlóideach agus an córas leictreonach. Ach tá an fheidhm de gach ceann de na hinreachtáin seo éagsúil. Déantar an slip ring agus an commutator as ábhar cosanta.

Sa tábla thíos, suimirímid na difríochtaí idir an slip ring agus an commutator.

Cineál Slip Rings

Raghmhaítear na slip rings i gcineál éagsúla de réir tógála agus méide. Cineál na slip rings a mheastar mar a leanas.

Pancake Slip Ring

In this type of slip ring, the conductors are arranged on a flat disc. This type of concentric disc placed on the center of a rotating shaft. The shape of this slip is flat. So, it is also known as a flat slip ring or platter slip ring.

It will reduce axial length. Therefore, this type of slip ring is designed for space-critical applications. This arrangement has more weight and volume. It has greater capacitance and greater brush wear.

Mercury Contact Slip Ring

In this type of slip ring, mercury contact is used as a conducting media. Under the normal temperature condition, it can transfer current and electrical signals by liquid metal.

The mercury contact slip ring features strong stability and less noise. And it provides the most scientific and economical option for applications in industries.

But the use of mercury creates a safety concern. Because it is a toxic substance. It is very dangerous to use this type of slip ring in applications like food manufacturing or processing and pharmaceutical. This is because it may corrupt the product if there is a mercury leakage.

Through Hole Slip Rings

This type of slip ring has a hole in the center of the slip ring. It is used in devices where requires to transmit power or signal when need 360˚ rotating.

This type of slip rings is designed to install with a flange on a sleeve bracket. It has free space in the center for connecting the shaft of a machine without affecting cable while it is rotating.

It has a long life span and offers low noise and maintenance. This type of slip ring is used for routing hydraulic pneumatic passages and it can integrate with high-frequency joints.

Through Hole Slip Rings

Ethernet Slip Ring

This type of slip ring is developed to provide reliable products that allow the transfer of the ethernet protocol through a rotary system.

While choosing an ethernet slip ring for communication, there are three important parameters that must be considered; Return Loss, Insertion Loss, and Crosstalk.

Ethernet slip rings designed to meet the requirement of matching impedance, reducing losses, and controlling crosstalk.

Ethernet Slip Ring

Miniature Slip Rings

This type of slip ring is very small in size and it is designed for small devices to transfer signals or power from a rotating device.
