Gear box for rack rail vehicle

Abstract

The utility model discloses a gear box for a rack rail vehicle, which can effectively remove potential pebbles or sundries on the surface of a rack through the innovative design of a sliding frame and a high-pressure spray head, and prevent the foreign matters from being accumulated or clamped between the rack and a rotating piece. The high-pressure spray head sprays airflow to the surface of the rack in a concentrated mode by accurately controlling the airflow direction, and thoroughness and pertinence of the cleaning effect are guaranteed. Meanwhile, through the synergistic effect of the air pump and the spray head, sundries on the rack can be rapidly removed, the cleaning state between the rack and the rotating piece can be maintained, and therefore loss and noise generated by friction are reduced. Therefore, not only is the mechanical wear effectively reduced, but also the operation stability of the rack rail system is remarkably improved, and the service life of the rack rail system is prolonged.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of gear box, concretely relates to a gear box for rack railway vehicle. BACKGROUND

[0002] In the running process of rack railway vehicle, the meshing between rack and rotating member is the key transmission mechanism, which directly affects the driving stability and efficiency of the vehicle. However, in the actual use process, the rack surface often accumulates small stones, dust and other sundries. The accumulation of sundries between the rack and the rotating member will cause poor meshing, increase friction, and even cause the failure of the gear box. In addition, the accumulation of sundries will also aggravate the wear of the rack and the rotating member, increase the noise of the system, and shorten the service life of the rack system.

[0003] Although the conventional gear box for rack railway vehicle solves the meshing problem in structure, it often lacks effective cleaning measures when facing the interference of sundries in the environment. The existence of sundries not only affects the transmission efficiency, but also causes unstable operation between the rack and the rotating member, and even affects the operation reliability of the whole system.

[0004] Therefore, the utility model is provided. CONTENT OF THE UTILITY MODEL

[0024] The utility model will be further described in detail in combination with the drawings.

[0025] Please refer to Figures 1-4 It is shown that in the embodiment, a gear box for rack railway vehicle is provided, which comprises a gear box body 1 and a rack 2 for guiding, a rotating part 3 engaged with the rack 2 is rotatably connected to one side of the gear box body 1, a cleaning structure is slidingly connected to the rack 2 in the vertical direction, a connecting plate 4 is fixedly connected to one side of the gear box body 1, and the connecting plate 4 is rotatably connected between the lower part and the cleaning structure, the cleaning structure comprises a sliding frame 5 slidingly connected above the rack and rotatably connected between the connecting plate 4, an air pump 6 is fixedly connected above the sliding frame 5, a plurality of high-pressure nozzles 7 are arranged in a straight line on the inner wall of the sliding frame 5 and are in communication with the air outlet of the air pump 6, and the air outlet of the high-pressure nozzle 7 faces the rack 2. It is further explained that there is a space between the top of the sliding frame 5 and the rack 2, and the arrangement of this structure avoids the occurrence of motion interference when the rack 2 goes uphill subsequently.

[0026] It should be noted that the rotating part 3 comprises a rotating disc, a through slot is formed in the circumferential side of the rotating disc, a plurality of supporting rods are connected between the inner walls of the through slot, and a space adapted to the teeth of the rack 2 is arranged between every two supporting rods, so as to realize the engagement with the rack 2.

[0027] The utility model is innovatively designed by the sliding frame 5 and the high-pressure nozzle 7, the system can effectively remove potential small stones or sundries on the surface of the rack 2, and prevent these foreign matters from accumulating or being stuck between the rack 2 and the rotating part 3. The high-pressure nozzle 7 can concentrate the airflow to the surface of the rack 2 by accurately controlling the airflow direction, so as to ensure the thoroughness and pertinence of the cleaning effect. At the same time, the cooperation of the air pump 6 and the nozzle can not only quickly remove the sundries on the rack 2, but also maintain the clean state between the rack 2 and the rotating part 3, thereby reducing the loss and noise caused by friction. In this way, not only the mechanical wear is effectively reduced, but also the running stability of the rack system is significantly improved, and the service life is prolonged.

[0028] Preferably, the air outlet of the air pump 6 is communicated with an air outlet pipe 8, and the lower part of the air outlet pipe 8 is communicated with a plurality of branch pipes 9, which penetrate into the interior of the sliding frame 5 and are communicated with the high-pressure nozzles 7. The high-pressure nozzles 7 on the first side and the second side of the inner wall of the sliding frame 5 are arranged in a staggered manner, and the air outlets of the high-pressure nozzles 7 are directed towards the gaps between the teeth of the rack 2. Through the arrangement of the high-pressure nozzles 7, the system can blow out the small stones, dust or other impurities in the rack 2, reducing the accumulation or jamming of these foreign matters between the rack 2 and the rotating member 3. When the rack 2 is engaged with the rotating member 3, any small impurities can cause the engagement to be not smooth, generate additional friction, and thus exacerbate the wear between the gear and the rack 2, or even cause jamming or damage. The design of the high-pressure nozzles 7 can blow away these impurities from the surface of the rack 2, so that the rack 2 and the rotating member 3 maintain clean and smooth contact, thereby reducing the engagement problems caused by foreign matter interference.

[0029] Preferably, one side of the sliding frame 5 is fixedly connected with a mounting plate 10, and the lower part of the connecting plate 4 is fixedly connected with a column body 11. The upper part of the mounting plate 10 is provided with a slot, and the interior of the slot is provided with a bearing. The bearing and the column body 11 are connected with each other to achieve the effect of sliding frame rotation. Through the arrangement of this structure, when the sliding frame 5 encounters a curve, it can adaptively adjust its position and angle to maintain smooth engagement between the rack 2 and the rotating member 3. Specifically, when the rack car drives to a curve, the flexible design of the sliding frame 5 enables it to automatically adjust according to the curvature of the track, and the relative position with the rack 2 remains consistent, thereby avoiding the problems of unstable engagement or excessive friction caused by angle changes. The adaptive adjustment function of the sliding frame 5 not only ensures that the rotating member 3 can smoothly follow the changes of the track, reduces the mechanical failures that may be caused by structural limitations, but also effectively improves the passability and stability of the vehicle in the curve.

[0030] Preferably, a plurality of sliding grooves 12 are formed on one side of the inner wall of the sliding frame 5, and a ball head seat 13 is elastically connected in the interior of the sliding groove 12. A ball 14 is rotatably connected in the interior of the ball head seat 13 and abuts against the lower part of the rack 2. A spring 15 is fixedly connected between the ball head seat 13 and the inner wall of the sliding groove 12, and the distance between the ball head seat 13 and the bottom of the inner wall of the sliding groove 12 is less than the radius of the ball 14. Through the arrangement of the spring 15, the ball 14 can be retracted into the sliding groove 12 when the sliding frame 5 and the rack 2 are subsequently combined, and then the ball 14 can contact the outer wall of the rack 2 through the deformation of the spring 15 after reaching the specified position to achieve the guiding effect. In addition, the arrangement of the ball 14 also causes a gap between the sliding frame 5 and the rack 2, which can facilitate the small stones inside the rack 2 to fall from the gap. Finally, the arrangement of the ball 14 also facilitates the subsequent sliding of the sliding frame 5.
