Abstract
The utility model provides a gear for a gear box of a railway locomotive. The gear has long service life and light weight. The gear is formed by embedding an oiling nylon outer ring and a steel inner ring; transmission teeth are arranged on the outer ring; a key slot is arranged in the center of the inner ring; and a plurality of crossed through holes are arranged at the periphery of the inner ring. According to the gear for the gear box of the railway locomotive, as the original all-steel structure is replaced by the composited structure of the oiling nylon outer ring and the steel inner ring, and the plurality of the crossed through holes are arranged at the periphery of the inner ring, the weight of the part is greatly reduced, the self-weight of the gear box of the whole railway locomotive is benefit to being reduced; in addition, as the oiling nylon outer transmission gear has excellent self-lubricating function, the working condition of the transmission gear can be improved, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of gear, and especially a kind of railway locomotive gearbox is used gear.
Background technique
The gear that uses in the existing rail vehicles gearbox generally is steel structure, thereby the deadweight of whole gearbox is heavier, makes that the deadweight of lorry locomotive is overweight, not only influences its Security, has also reduced the lifting capacity and the conveying efficiency of locomotive.And the steel surface easy abrasion, working life is lower.
The model utility content
The utility model provides a kind of long service life, and lightweight railway locomotive gearbox is used gear.
Realize that the railway locomotive gearbox of the utility model purpose uses gear, inlayed by the outer ring of oil-containing nylon material and steel inner ring and form that said outer ring is provided with driving cog, said inner ring center is provided with keyway, and said inner ring periphery is provided with the through hole of a plurality of cross-distribution.
The beneficial effect of the utility model is following:
The railway locomotive gearbox of the utility model is used gear; Owing to adopt the outer ring of the oil-containing nylon structure alternative original full steel structure mutually compound, and be provided with the through hole of a plurality of cross-distribution, not only greatly reduce the weight of parts at the periphery of inner ring with the steel inner ring; Help the reduction of whole locomotive wheel gearbox deadweight; And because the driving cog of oil-containing nylon material has good self-lubricating property, thereby can improve its operating conditions, prolong its working life.
Description of drawings
Fig. 1 is the structural representation of the utility model railway locomotive gearbox with gear.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1; The railway locomotive gearbox of the utility model is used gear, is inlayed by the outer ring 1 and the steel inner ring 2 of oil-containing nylon material to form, and said outer ring 1 is provided with driving cog 11; Said inner ring 2 centers are provided with keyway 21, and said inner ring 2 peripheries are provided with the through hole 3 of a plurality of cross-distribution.
The railway locomotive gearbox of the utility model is used gear; Because the alternative original full steel structure of structures that the outer ring 1 of adopting oil-containing nylon and steel inner ring 2 are mutually compound, and be provided with the through hole 3 of a plurality of cross-distribution, not only greatly reduce the weight of parts at the periphery of inner ring 2; Help the reduction of whole locomotive wheel gearbox deadweight; And because the driving cog 11 of oil-containing nylon material has good self-lubricating property, thereby can improve its operating conditions, prolong its working life.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in related domain make the utility model technological scheme all should fall in the protection domain that claims of the utility model confirm.
