TECHNICAL FIELD
[0001] The utility model relates to a rack train technical field especially relates to a rack train drive mechanism. BACKGROUND
[0002] The rack train is applied to the rack railway, and the gears on the rack train play a big role - the gears on the rack train mesh with the rack installed in the middle of the track when climbing, thereby generating the meshing force, so that the train can safely run on the slope of 480 ‰, and is suitable for the sightseeing line in the mountainous area or the tourist attraction.
[0003] However, the drive mechanism used in the current rack train is heavy when fully loaded, and the gears are pressed on the rack, which not only produces loud noise when meshing, but also easily causes wear and tear. CONTENT OF THE UTILITY MODEL
[0004] In order to solve the above-mentioned defects, the utility model provides a rack train drive mechanism, which solves the problem of large noise and large wear and tear of the traditional rack train when climbing.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0006] A rack train drive mechanism, comprising a rack arranged along the track and a drive mechanism assembly arranged on the rack train and meshing with the rack, the rack is arranged on the side of the track, the drive mechanism assembly comprises a bracket, a motor arranged on the bracket, a driving wheel meshing with the rack and a driven fixed wheel set for fixing the rack train to slide on the track, the driving wheel is a roller and is arranged parallel to the rack.
[0007] Further, the track comprises an upper track, a lower track and a support column connected and fixed between the upper track and the lower track.
[0008] Further, the driven fixed wheel set comprises a first wheel set and a second wheel set, which are respectively connected with the upper track and the lower track of the track.
[0009] Further, the track is further provided with a slide wire, and the motor obtains power from the slide wire through the carbon brush.
[0010] The beneficial effects produced by the above-mentioned technical scheme are:
[0011] By setting the meshing drive of the roller and the rack, the rolling engagement between the rolling pin of the roller and the rack is adopted, which can realize zero backlash in both forward and reverse directions, ensure high precision and high speed transmission, and at the same time, due to the rolling engagement between the roller and the rack, the friction and wear are reduced, thereby reducing the noise and vibration.
