Locomotive of the present utility model is with lubricating change speed gear box in the complementary type, comprise lower box and the upper box that links to each other with lower box, transmission shaft and gear are installed in upper box and lower box, transmission shaft comprises first transition axis, the right oil pump of one termination of first transition axis, the suction inlet of right oil pump is connected with the oil sump of cabinets cavity by the oil duct on the lower box sidewall, row's mouth of right oil pump is connected with right oil distributor by the oil duct on the upper box sidewall, the outlet of right oil distributor and the longitudinal tubule (L tubule) that is positioned at the casing outside and first transverse tube and second transverse tube that are positioned at box inside are connected, and longitudinal tubule (L tubule) has oil outlet to be used for lubricating bearing at the bearing place of each transmission shaft; Described first transverse tube middle part connects first oil nozzle, and second transverse tube middle part connects second oil nozzle; Another termination left side oil pump of first transition axis, the suction inlet of left side oil pump is connected with the oil sump of cabinets cavity by the oil duct on the lower box sidewall, row's mouth of left side oil pump is connected with left oil distributor by the oil duct on the upper box sidewall, and the outlet of left oil distributor is connected with the longitudinal tubule (L tubule) that is positioned at the casing outside.
Locomotive of the present utility model is with lubricating change speed gear box in the complementary type, the passage place that is communicated with each oil pump suction inlet on the wherein said lower box is provided with lubricating filtering device.
Locomotive of the present utility model is with lubricating change speed gear box in the complementary type, owing to be equipped with oil pump in the both sides of casing, two oil pumps are simultaneously to each lubricating point fuel feeding, can realize complementation, above the case inner gear, increased oil nozzle, further guarantee the lubricated of case inner component, had the lubricated phenomenon such as the serious or scaling loss of component wear that well, can not occur.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is a schematic top plan view shown in Figure 1;
Fig. 3 is that a left side shown in Figure 1 is looked and analysed and observe enlarged diagram.
The specific embodiment
As shown in Figure 1, 2, 3: 7 is upper box, and 4 is lower box, is supported with transmission shaft by bearing on upper box 7 and lower box 4, and the driving cog axle is installed on the transmission shaft.Transmission shaft comprises interchange auxiliary generator end axle 16, first transition axis 17, diesel engine main generator end axle 18, second transition axis 19, the starter motor end axle 20 that is arranged in parallel.
At the right oil pump 9 of a termination of first transition axis 17, right oil pump 9 is bolted to connection in the casing outside.The suction inlet of right oil pump 9 is connected with the oil sump 1 of cabinets cavity by the oil duct on lower box 4 sidewalls.Row's mouth of right oil pump 9 is connected with right oil distributor 8 by the oil duct on upper box 7 sidewalls, and right oil distributor 8 is bolted to connection in the casing outside.The outlet of right oil distributor 8 be positioned at casing outside longitudinal tubule (L tubule) 21 and first transverse tube 14 and second transverse tube 15 that is positioned at box inside be connected.Longitudinal tubule (L tubule) 21 has oil outlet to be used for lubricating bearing at the bearing place of each transmission shaft.
First transverse tube, 14 middle parts connect first oil nozzle, 12, the first oil nozzles 12 and are positioned at the top that exchanges the gear on the auxiliary generator end axle 16; Second transverse tube, 15 middle parts connect the top that second oil nozzle, 13, the second oil nozzles 13 are positioned at the gear on the starter motor end axle 20.
Another termination left side oil pump 5 of first transition axis 17, left oil pump 5 is bolted to connection the outside at casing.The suction inlet of left side oil pump 5 is connected with the oil sump 1 of cabinets cavity by the oil duct on lower box 4 sidewalls.Row's mouth of left side oil pump 5 is connected with left oil distributor 6 by the oil duct on upper box 7 sidewalls, and left oil distributor 6 is bolted to connection the external side of raising middle flask.The outlet of left side oil distributor 6 is connected with the longitudinal tubule (L tubule) 21 that is positioned at the casing outside.Formed symmetrical oil supply structure, two oil pumps reach complementary purpose.
