Definitions

  • the invention relates to a spray nozzle for a wheel flange lubricating device of a rail vehicle, through which lubricant, in particular fluid grease, with an air pressure between approximately 3.5 and 7 bar in a spray jet consisting of a lubricant / air mixture onto the wheel flange inner surface of a wheel Rail vehicle is sprayed with a lubricant-air mixture channel, which merges into a bore forming the nozzle tip.
  • Wheel flange lubrication for rail vehicles serves the purpose of reducing the wear of the wheel and the rail in the area of the wheel flange.
  • a system consists of a container for the lubricant under air pressure.
  • the container is connected by a lubricant line to one or more spray nozzles, which are arranged on the inside in the direction of travel of the rail vehicle in front of the wheels of the steering axle and are directed in such a way that the inner surface of the flanges and also the starting radius of the wheel are lubricated. It should be avoided that the running ring is also wetted by lubricant.
  • a compressed air line is connected in front of each spray nozzle and is connected to a compressed air source via a solenoid valve.
  • the solenoid valve is controlled by a timer for intermittent air passages, so that intermittent pressurized air takes place at each spray nozzle.
  • Lubricant is under pressure in each spray nozzle via the lubricant supply line and is expelled from the spray nozzle in precise doses with each compressed air supply in the direction of the inner surface of the flange. Lubrication is therefore carried out using a spray jet consisting of a lubricant-air mixture.
  • Technology has long been concerned with the adverse effects of air swirls and wind as well as due to the wheel rotation on the grease-air mixture spray jet to avoid and stabilize the spray.
  • the invention is based on the object of achieving an improved, precise lubricant supply to the surface to be wetted in the wheel flange lubrication of rail vehicles and thereby stabilizing the spray jet to such an extent that the lubricant scattering particles are prevented from breaking out.
  • the nozzle opening is designed as a bore with a diameter of less than 2 mm, preferably 1.6 mm, with a bore length of less than 6 mm, preferably 4.8 mm, and the ratio of bore diameter to bore length is 1: 3, and that the bore is preceded by a long transition cone to the lubricant-air mixture channel, which has an included angle of less than 25 °, preferably 20 °.
  • the inventive design of the nozzle bore contributes significantly to the stabilization of the spray jet. Basically, it was found that the flow behavior of the outside air to the spray jet is all the more favorable the smaller the diameter of the nozzle opening at the nozzle tip and the smaller the harmful vacuum space at the spray jet outlet. In contrast to previous spray nozzles, an extraordinarily fine nozzle opening is therefore proposed with the invention.
  • the design of the nozzle bore also contributes to the stabilization of the spray jet. It has been found that a favorable ratio of bore diameter to bore length is approximately 1: 3. Due to the corresponding bore length, the flow air is pressed with the lubricant particles and stabilized for the spray jet. Longer bores disadvantageously result in pressure losses.
  • the long transition cone provided according to the invention which promotes the more uniform distribution of the lubricant in the mixture, also works in combination with the above features.
  • the lubricant is transported in the lubricant-air mixture channel to the nozzle opening in such a way that the lubricant is driven helically on the channel wall and bore wall by the air flow to the outlet.
  • the elongated cone in the transition area is matched to this transport mechanism in the sense of homogenizing the mixture.
  • a draft shield in the form of a jacket surrounding the nozzle opening and projecting above it, which is provided with flow openings for axial air flows at the rear in the spraying direction.
  • This jacket surrounding the nozzle tip with openings provides excellent protection against air swirls, headwinds and radial winds in the sense of rejection, whereby through the openings in the windbreak jacket with the spray jet function, axial air flows can take place and are promoted, which in turn is a have additional protective function. Due to the axial air currents, the contact outside air bound with the spray jet is entrained approximately tangentially by the spray jet, so that no spray jet expansion can take place and lubricant particles are prevented from breaking out of the spray jet. As a result, the effect of the concave outer contour is functionally supported and reinforced by the design of the wind protection jacket.
  • the wind protection jacket In addition to this effect of the wind protection jacket, it also provides protection against mechanical damage to the nozzle tip. In this sense, it is structurally advantageous to attach the wind protection jacket as a tubular extension to the nozzle body, the rear flow openings being attached to the ring flange of the tubular extension provided for attachment are provided in a star shape.
  • the spray nozzle it is advantageous to operate the spray nozzle with an operating air pressure of 4 to 6.5 bar. Higher pressures cause an undesirable lubricant blowing effect at the friction point, while pressures that are too low negatively influence the concentration of the spray jet, especially in the minus temperature range. It should be noted that a function down to -30 ° must be guaranteed.
  • the proposal of the invention achieves a controlled lubricant supply with a stabilized and homogenized spray jet to the surface of the rail vehicle to be wetted. Leakage of lubricant particles is avoided, so that undesirable contamination, lubricant loss and environmental pollution are minimized.
  • the nozzle is lubricated by intermittent compressed air.
  • this is connected to a compressed air source, not shown, via a compressed air line, a solenoid valve and a timing element.
  • the solenoid valve is controlled by the timer for intermittent compressed air openings.
  • a spray nozzle 1 according to the attached drawing is provided. It consists of a nozzle body 2 having a lubricant-air mixture channel 3 and a nozzle mouthpiece 4 with a nozzle opening 5. It is in the drawing not shown, since it is known per se that the compressed air line for intermittent pressurized air and the lubricant line 6 of the associated wheel of the rail vehicle according to FIG. 1 of the drawing is attached to the nozzle body 2.
  • the compressed air is used in the pressure range of approx. 4 to 6.5 bar.
  • the nozzle opening 5 is designed as a bore 7 with a diameter of 1.6 mm.
  • the bore length is 4.8mm, so that the ratio of bore diameter to bore length is 1: 3.
  • the bore 7 is preceded by a long conical transition cone 8 to the lubricant-air mixture channel 3.
  • the transition cone 8 has an included angle of 20 °.
  • the nozzle mouthpiece 4 is concave in its front area adjacent to the nozzle opening 5 in its outer contour 9.
  • the air flow generated in this way along the nozzle mouthpiece 4 is illustrated in FIG. 1 of the drawing by arrows 10. It can be seen that a tangential leaning of the entrained outside air during the spraying process on the spray jet is achieved by the contouring.
  • the nozzle mouthpiece itself is an independent add-on unit that can be used with nozzle bodies 2 of the prior art, so that a simple modernization of previous wheel flange lubrication devices is possible. It is only necessary to screw the nozzle mouthpiece 4 into the corresponding connection bore 11 of the nozzle body 2 and thus to establish the connection to the lubricant-air mixture channel 3.
  • the nozzle mouthpiece 4 is provided with a draft shield 12 in the form of a tubular jacket 13 which surrounds the nozzle opening 5 and projects beyond it and which is provided at the rear with flow openings 14 for axial air flows.
  • a draft shield 12 in the form of a tubular jacket 13 which surrounds the nozzle opening 5 and projects beyond it and which is provided at the rear with flow openings 14 for axial air flows.
  • These are star-shaped in an annular flange 15, as can be seen in FIG. 3 of the drawing.
  • the ring flange 15 is screwed to the nozzle mouthpiece 4 behind the concave-shaped tip and can therefore be used and retrofitted as required, in particular for high-speed rail vehicles.
  • Of the Pipe jacket is designed as a hexagon for the purpose of simple screwing.
