Embodiment Construction
[0025] The present invention will be described in detail below.
[0026] A method for stepwise replacement of traction gears for rack trains, comprising the following steps:
[0027] Step 1: Divide the wheel wear into several wear grades, each wear grade corresponds to a different wheel diameter, and equip traction gears of corresponding sizes for each wear grade;
[0028] Step 2: After the rack train runs for a certain period of time or a certain mileage, the diameter of the wheel is detected to determine whether the wear condition reaches the corresponding wear level;
[0029] Step 3: If the wear condition of the wheel reaches the corresponding wear level, replace the original traction gear with a traction gear with a size corresponding to the wear level.
[0030] The process of changing the traction gear in the third step is as follows:
[0031] Step 3.1, prepare the gear delivery tool, specifically: place the gear delivery tool directly under the lower half gear, and use...

A method for the grade replacement of the traction gear for a gear-track train is disclosed. The method includes such steps as dividing wheel wear into several wear grades, each wear grade correspondto different wheel diameters, and equipping traction gears with corresponding sizes corresponding to each wear grade, replacing that wheel wear grades with different wheel diameters according to different wheel diameters, and replacing the wheel wear grades with different wheel diameters. Wheel diameter of gear-track train is measured after a period of time or a certain number of mileage. If wheelwear reaches the corresponding wear level, replace the original traction gear with a traction gear of the size corresponding to the wear level. As that wheel rim is abrade or the wheel is upgraded tothe correspond grade, the traction gear of the corresponding grade can be replaced to meet the traction demand of the gear track, and the problem that the traction gear and the gear track rack of thegear track train are stuck after the wheel rim is abraded and the center distance becomes small is solved; The replaced traction gears can be reserved after passing the inspection, and the number oftraction gears is less than that of the wheels, so the corresponding grade traction gears that need to be reserved are also less, and the replacement cost is low.
Description
technical field [0001] The invention relates to a method for stepwise replacement of traction gears for cog trains, belonging to the technical field of locomotive rail transit. Background technique [0002] The cog railway is provided by setting a special cog in the middle of the ordinary track. A locomotive running on a rack railway is equipped with one or more traction gears that mesh with the racks to pull the train up a steep slope with a relatively large gradient. Through this combination of steel rails and cog rails, the train can run on flat ground and mountain-climbing railways with large slopes, and passengers do not need to transfer. [0003] There is wear between the traction gear and the rack, but compared with the wear between the wheels on both sides of the train and the track, the wear between the traction gear and the rack is much slower, because the situation of steep slopes is much less after all. Therefore, after the train runs for a period of time, when...
