Definitions

  • the object of this invention is a method to arrange cooling in a com- pactor equipped with at least one roller drum, in which the motor and/or other equipment, for example the hydraulic system, has forced circulation water cooling or water-cooled forced circulation air cooling.
  • the inven ⁇ tion is also concerned with a cooling system intended to realize the method.
  • forced circulation water is taken to mean any liquid substance at all applicable to heat exchange, most typically a mixture of water and an anti-freeze substance.
  • the field of the invention includes the solution in accor ⁇ dance with US publication 4342485, which presents the partial immersion cooling of a planetary gearbox installed in the drum of a cold surface planer for concrete and asphalt surfaces. According to this the cooling is improved by partially filling the drum with liquid coolant, which ef ⁇ fectively conducts the heat from the surface of the gearbox to the surface of the drum. It is the intention of this invention to create a simple method to ar ⁇ range the cooling in a compactor and a cooling system to realize the cooling system. With the aid of the invention an attempt is made to remove the problem of dirt in the aforementioned known forced circulation water cooling systems.
  • axle shaft means also one-piece axle ends, in which corresponding channels to the centre of the drum have been formed.
  • Figure 1 shows a compactor, in which there is roller drum cooling.
  • Figure 2 shows diagraim ⁇ atically the principle of the cooling system.
  • Figure 3 shows the arrangment of the water connection to the roller.
  • Figure 4 shows the arrangment for the circulation of water inside the spikes of the roller.
  • the typical power of the motor of a large compactor is 400 hp. In a compactor of this kind a maximum cooling power of about 110 kW is required when the cooling requirement of the hydraulic system is included.
  • the length of the rollers of the compactor in Figure 1 is about 4m and their surface area is sufficient to transmit the heat from the roller even under hot conditions. What makes the invention especially advantageous is that the length of the roller and thus its heat exchange surface area is nearly comparable to the size of the compactor and its motor in modularly con- structed compactors.
  • the roller drum cooling in accordance with the in ⁇ vention can thus be applied easily and by exploiting the mohular method of construction in all sizes of compactors.
  • the motor 1 has a separate forced circulation water circuit •%, which is cooled by means of heat exchanger 14 connected to the roller 3 by means of an auxilliary forced circulation water circuit.
  • the cooler 13 for the hydraulic oil is also installed on this auxilliary circulation circuit, Figure 2.
  • the auxilliary circulation circuit consists of, in addition to the roller 3, an inlet and return pipe 10, a pump 12, and the aforementioned heat exchangers 13 and 14.
  • the roller 3 also forms an expansion reservoir when a space 8 for gas has been left in it. It can be easily observed from Figure 2 that from the point of view of the invention it makes no difference even if the motor has closed forced air cooling in place of the aforementioned water cooling.
  • the water heated in the motor l ⁇ and the hydraulic system 2 is led along the inlet pipe 10 and through the pressure bearing 15 and the axle shaft 9 to the roller 3 and is taken out through the opposite end.
  • the circu ⁇ lating water comes in contact with the outer cover 5 of the roller 3, in which case the heat exchange is convective snd thus effective.
  • the pump ⁇ .12 which creates the flow of the circulation, in located at the coldest part of the flow circuit, i.e. before the aforementioned heat exchangers 13 and 14.
  • roller 3 itself is in principle a stiffened cylinder, at the ends of which axle shafts 9 are secured.
  • Pipe 16 is fitted through one end, and at its end is the pressure bearing 15 which is connected to inlet pipe 10. This creates a watertight connection which permits, however, the roller ⁇ to remove normally.
  • the outlet pipe 11 is connected in a corresponding man ⁇ ner to the other side of roller 3»
  • Roller 3 is supported by the bearings 17, which are secured to a housing fixed to frame 19. Drive to roller 3 takes place by means of chainwheel 18.

Abstract

Procédé d'agencement du refroidissement dans un compacteur équipé d'au moins un rouleau compresseur (3), dans lequel le moteur et/ou un autre équipement, par exemple le système hydraulique, possèdent un refroidissement par eau de circulation forcée ou un refroidissement par air de circulation forcée en circuit fermé refroidi par eau. L'invention se propose de remédier au problème du salissement des cellules de radiateur, qui existe dans les systèmes de refroidissement actuels. Dans le procédé ci-décrit, on fait circuler l'eau de refroidissement à travers le rouleau (3) et on l'amène en contact avec le revêtement extérieur (5) du rouleau afin de transférer la chaleur de celui-ci à l'air ambiant et au sol.
