Abstract

The two drive motors (6,8) are coupled via an outgoing shaft (12) for rotation of the unit (4) on the bar (2), and are mechanically series coupled. The outgoing shaft is that for output of one of the motors (8), and on it is a flywheel (16). A brake mechanism (28) acts on the more remote end of the outgoing shaft, and the two motors are supported in a parallel arrangement by a common frame. The motor located closest to the outgoing shaft is arranged to idle when the lift cage runs downwards, and is coupled to its partner by a belt drive (20-26). Likewise, the rotatable unit (4) is coupled to the outgoing shaft by a belt drive (14,18). The bar and the rotatable unit are, respectively, a screw and a nut.

Description

458 678 2 Motorerna 6 och 8 uppbärs parallellt som en drívenhet av en gemensam bärram 10 monterad på ej närmare visat sätt på hisskorgens tak. Motorn 8 har på sin utgående axel 12 en remskiva 14 och ett svänghjul 16. Remskivan 14 och en med muttern 4 förbunden, ej närmare visad remskiva är hopkopplade medelst driv- remar 18. På motorns 6 utgående axel 20 sitter en remskiva 22, som via drivrem- mar 24 är drivmässigt hopkopplad med en remskiva 26, som sitter på motorns 8 se- kundåraxel. . 458 678 2 The motors 6 and 8 are supported in parallel as a drive unit by a common support frame 10 mounted in a manner not shown in more detail on the roof of the elevator car. The motor 8 has on its output shaft 12 a pulley 14 and a flywheel 16. The pulley 14 and a pulley connected to the nut 4, not shown in more detail, are connected by means of drive belts 18. On the output shaft 20 of the motor 6 there is a pulley 22 which drive belts 24 are operatively coupled to a pulley 26 located on the secondary shaft of the motor 8. .

På motorns 6 sekundäraxel verkar en elektriskt aktiverbar broms 28 med samma funktion som den i patentskriften 8502693-8 beskrivna, elektriskt aktiver- bara bromsen.An electrically actuable brake 28 with the same function as the electrically actuable brake described in patent specification 8502693-8 acts on the secondary shaft of the engine 6.

I drift samverkar de båda nntorerna 6 och 8 för uppfärd av hisskorgen.In operation, the two lanes 6 and 8 cooperate for the erection of the elevator car.

Vid nedfärd däremot arbetar endast motorn 6, varvid således motorn 8 löper i tomgång och överför drivkraften till fluttern 4 via remdriften 14, 18. Med andra ord arbetar alltid motorn 6 när hissen är i drift, medan motorn 8 endast arbetar vid uppfärd. ' Vid ett praktiskt utförande av drivarrangemangen enligt uppfinningen var motorn 6 en 1,5 kw elmotor och motorn 8_var på 2,2 kw.When descending, on the other hand, only the motor 6 operates, whereby the motor 8 thus runs at idle and transmits the driving force to the fl otter 4 via the belt drive 14, 18. In other words, the motor 6 always works when the lift is in operation, while the motor 8 only works when driving. In a practical embodiment of the drive arrangements according to the invention, the motor 6 was a 1.5 kw electric motor and the motor 8 was 2.2 kw.
