Abstract
The utility model relates to a gear box of locomotive, which comprises an active axle group, a first pony axle group, an auxiliary engine axle group, a second pony axle group and a start motor axle group which are parallel arranged, wherein the start motor axle of the start motor axle group and the second pony axle of the second pony axle group, the second pony axle of the second pony axle group and the active axle of the active axle group, the active axle of the active axle group and the first pony axle of the first pony axle group, and the first pony axle of the first pony axle group and the auxiliary engine axle of the auxiliary engine axle group are meshed via helical gears. Each transmission gear use helical gear to eliminate the foreign sound of prior straight gear box and reduce noise. And via the helical gears, the transmission power can reach 500KW, to improve transmission efficiency.
Description
Technical field
The utility model relates to a kind of locomotive gearbox.
Background technique
Gearbox is a critical piece of locomotive accessory drive system.Problems such as existing locomotive gearbox adopts the spur gear structure, exists different sound, noise big, and transmitted power is little.
The model utility content
Technical problem to be solved in the utility model provides the locomotive gearbox that a kind of noise is little and transmitted power is bigger.
For solving the problems of the technologies described above, locomotive gearbox of the present utility model comprises: the driving shaft group that be arranged in parallel, one group on lazy axle, donkey engine axle group, lazy axle two groups and actuating motor axle group; It is characterized in that: between the lazy axle two that the actuating motor axle of actuating motor axle group and lazy axle are two groups, between the driving shaft of the lazy axle two of two groups on lazy axle and driving shaft group, between the lazy axle one of the driving shaft of driving shaft group and one group on lazy axle and be helical gear between the donkey engine axle of lazy of one group on lazy axle and donkey engine axle group and mesh.
In the technique scheme, described helical gear helix angle is the 12-15 degree.
In the technique scheme, the helical gear of the helical gear of actuating motor axle, lazy axle two, the helical gear of driving shaft, the helical gear of lazy axle one and the helical gear gear ratio of donkey engine axle are 23: 47: 64: 47: 21.
The utlity model has positive effect: each driving gear in (1) locomotive gearbox of the present utility model adopts helical gear, has eliminated the different sound that former spur gear gearbox is used to have, and greatly reduces noise; After adopting helical gear, the power of transmission can reach 500kW, has improved transmitted power.(2) in the utility model, described helical gear helix angle is the 12-15 degree, is beneficial to the reduction noise.(3) in the utility model, the gear ratio of actuating motor axle, lazy axle two, driving shaft, lazy axle one and donkey engine axle is 23: 47: 64: 47: 21, be suitable for the high-power transmission of helical gear.
Description of drawings
Fig. 1 is the internal mechanism schematic representation of locomotive gearbox.
Embodiment
(embodiment 1)
See Fig. 1, the locomotive gearbox of present embodiment comprises: the driving shaft group that be arranged in parallel, one group on lazy axle, donkey engine axle group, lazy axle two groups and actuating motor axle group; It is characterized in that: between the lazy axle 24 that the actuating motor axle 5 of actuating motor axle group and lazy axle are two groups, between the driving shaft 1 of the lazy axle 24 of two groups on lazy axle and driving shaft group, between the lazy axle 1 of the driving shaft 1 of driving shaft group and one group on lazy axle and be helical gear between the donkey engine axle 3 of lazy 1 of one group on lazy axle and donkey engine axle group and mesh.
Each driving gear adopts helical gear, has eliminated the different sound that former spur gear gearbox is used to have, and greatly reduces noise; After adopting helical gear, the power of transmission can reach 500kW, has improved transmitted power.
Described helical gear helix angle is the 12-15 degree, is beneficial to the reduction noise.
The helical gear of the helical gear of actuating motor axle 5, lazy axle 24, the helical gear of driving shaft 1, the helical gear of lazy axle 1 and the helical gear gear ratio of donkey engine axle 3 are 23: 47: 64: 47: 21, modulus was 6, and facewidth 90mm is suitable for the high-power transmission of helical gear.
For guaranteeing that gear and bearing obtain lubricated fully and cooling, the locomotive gearbox of present embodiment adopts and forces the pressure oil lubricating system, and lubricant oil should be given bearing, gear lubrication in the casing, and the heat energy that gear, pivot friction are produced is taken away again.
