Abstract
Účelom iriešenia je umožnenie merania plazivých aklzov na odstredivej spojike, Uvedeného ciel'a sa dosiahne zariadením, ktoré má na jednom konci dutého hriadela upravený bubon odstredivej spojky a na druhotm clonu s otvormi prechádzajúcimi pomedzi světelný zdroj a fotodiódu a v du- tom hriadeli je uložený hriadel', ktorý má na (konci pri bubne odstredivej spojky při pojené skúšané zariadenie a na opačnom konci clonu s otvormi prechádzajúcimi po medzi světelný zdroj a fotodiódu.The purpose of the solution is to enable the measurement of creepage slips on a centrifugal clutch. The above-mentioned objective is achieved by a device that has a centrifugal clutch drum arranged at one end of a hollow shaft and a screen with openings passing between a light source and a photodiode at the other end, and a shaft is placed in the hollow shaft, which has a device under test connected at the end near the centrifugal clutch drum and a screen with openings passing between the light source and the photodiode at the opposite end.
Description
Vynález sa týká skúšobného a zabehávacieho zariadenia, ktoré je vhodné pre sklúšky a zátbeh imenších hnacích agregátov, najma motorov, opatřených samočinnou odstředivou spojkou.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test and run-in device which is suitable for the treads and loads of smaller propulsion assemblies, especially motors equipped with an automatic centrifugal clutch.
Každý vyrobený hnací agregát je nutné po skompletqvaní odsikúšať z hlediska požadovaných funkčných a prevádzkových parametrov ako sú požadovaný výkon, otáčky, krútiaci moment a pod. U agregátov pracujúcich so samočinnou odstředivou spojkou je tiež potřebné zisťiť otáčky, pri ktorých dochádza k zapnutiu spojky a případný preklz spojky pri práci. Tým sa súčasne hnací agregát zabieha.Each drive unit produced must be tested for the required functional and operating parameters, such as required power, speed, torque, and so on. It is also necessary to determine the speed at which the clutch is switched on and any clutch slip during operation when using units with automatic centrifugal clutch. This simultaneously drives the drive assembly.
Známe konštrukcie skúšobných zariadení pre skúšky a zábeh kompletných hnacích agregátov sú riešené ako masivně konštrukcie, s mechanicko-elektrickým snímáním požadovaných veličin.Known designs of testing equipment for testing and running of complete drive aggregates are designed as massive structures, with mechanical-electrical sensing of required quantities.
Nevýhodou tohto riešenia je nízká přesnost merania obtiažna montáž agregátu na skúšohný stav a vysoká obtiažnosť a nepřesnost stanovenia otáčok a okamihu zapnutia samočinnej spojky. Tieto zariadenia prakticky neumožňujú meranie a vyhodnocovanie malých, tzv. plazivých sklzov.The disadvantage of this solution is the low measurement accuracy of the difficult assembly of the unit to the test state and the high difficulty and inaccuracy of the determination of the speed and the moment of switching on the automatic clutch. These devices practically do not allow the measurement and evaluation of small, so-called creep slopes.
Uvedené nevýhoidy odstraňuje skúšobné a zaběhav,acie zariadenie podta vynálezu, ktorého podstata spočívá v tom, že v nosnom telese je otočné uložený dutý hriadel', opatřený na jednom konci buhnom odstredivej spojky a na druhom konci clonou, v ktorej sú vytvořené otvory pre přechod světelného lúča zo světelného zdroja na fotodiódu. Dutý hriadel’ je prostredníctvom řemenice a remeňa přepojený s dynamometr om. V dutom hriadeli je uložený hriadel' opatřený na straně odstredivej spojky spojkou pre spojenie s klukovým hriadelom skúšaného agregátu. Na protilahlej straně je dutý hriadel' opatřený clonou, v ktorej sú vytvořené otvory pre přechod světelného lúča zo světelného zdroja na fotodiódu. Výhody skúšobného a zahehávacieho zariadenia podta vynálezu spočívajú v jeho konštrukčnej jednoduchosti a tým aj funkčně j spoíahlivosti a v možnosti vyhodinocovania aj tzv. plazivých sklzov ha samočinnej odstredivej spojke hnacieho agregátu. Příklad prevedenia zariadenia podía vynálezu je na výkrese, ktorý znázorňuje rez zariadením vo zvislej osi.The above-mentioned disadvantages are eliminated by the test and run-in device according to the invention, characterized in that a hollow shaft is provided in the support body, provided at one end with a centrifugal clutch and at the other end with a diaphragm in which openings for the transition of light beam from light source to photodiode. The hollow shaft is coupled to the dynamometer by means of a pulley and a belt. A shaft is provided in the hollow shaft provided with a coupling on the side of the centrifugal coupling for connection with the shaft of the tested unit. On the opposite side, the hollow shaft is provided with an aperture in which openings are provided for passing the light beam from the light source to the photodiode. The advantages of the test and heating apparatus of the invention lie in its structural simplicity and thus its function reliability and in the possibility of decoupling the so-called creep chutes and the automatic centrifugal clutch of the drive assembly. An example of an embodiment of the device according to the invention is shown in the drawing which shows a section of the device in the vertical axis.
Zariadenie pozostáva z nosného telesa 1, v ktorom je na ložiskách 2 uložený dutý hriadel 3, opatřený na jednom konci vonkajším bubnom 4 odstredivej spojky a na druhom konci clonou S opatřenou otvormi 6, cez ktoré fotodióda 7 snímá impulzy světelného zdroja 8. V dutom hriadeli 3 je uložený hriadel' 10, opatřený na jednom konci spojkou 11 pre spojenie s klukovým hriadelom 12 sklúšaného agregátu 13 a na druhom konci clonou 14 s otvonmi 15, cez ktoré fotodióda 16 snímá impulzy světelného zdroja 17 ,a tým aj otáčky klukového hrladela 12.The device consists of a support body 1 in which a hollow shaft 3 is provided on the bearings 2 provided with an outer drum 4 of the centrifugal clutch at one end and an aperture 6 with openings 6 through which the photodiode 7 detects the pulses of the light source 8. In the hollow shaft 3, a shaft 10 is provided, provided at one end with a coupling 11 for connection to the crankshaft 12 of the lowered aggregate 13 and at the other end with a aperture 14 with openings 15 through which the photodiode 16 senses the pulses of the light source 17 and thus the speed of the crank shaft 12.
Hriadel1 3 je súčasne opatřený remenioou 18, cez ktorú je remeň 19 spojený s dynamometrem 20. Otáčky klukového hriadela 12 a vonkajšieho bubna 4 odstredivej spojky sú elektronicky vyhodnocované a porovnávané, čím je možné stanovit presne okamih zapnutia odstredivej spojky a případné preklzy.At the same time, the shaft 3 is provided with a remenium 18 through which the belt 19 is connected to the dynamometer 20. The speed of the crankshaft 12 and the outer drum 4 of the centrifugal clutch are electronically evaluated and compared, whereby the moment of switching on the centrifugal clutch and any slippage can be determined.
