Abstract
The utility model relates to a bearing seat for railway rolling stock speed-variation box which belongs to rolling stock accessory. The bearing seat for railway rolling stock speed-variation box comprises a base which is made from nylon composites of casting mold, a setting hole on the base, and a bushing which is made from oiliness nylon composites and embedded in the setting hole. The utility model with the light weight and long service time can meet the requirement of strength.
Description
Technical field
The utility model belongs to the train locomotive annex, relates to a kind of rail vehicles gearbox bearing support.
Background technique
Each component that comprise bearing support that use in the existing rail vehicles gearbox generally are steel structure, thereby whole gearbox deadweight is heavier, make that the deadweight of lorry locomotive is overweight, not only influence its Security, also reduced the lifting capacity and the conveying efficiency of locomotive.In addition, parts movingly such as bearing support, its steel surface weares and teares easily, and working life is lower.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can satisfy requirement of strength, the rail vehicles gearbox bearing support of in light weight simultaneously, long service life.
Rail vehicles gearbox of the present utility model includes a pedestal of being made by the monomer cast nylon material with bearing support, has mounting hole on pedestal, is embedded with the lining of being made by the oil-containing nylon material in mounting hole.
The utility model is owing to adopt the mutually compound structure of oil-containing nylon lining and monomer cast nylon pedestal to substitute original full steel structure bearing support, not only greatly reduce the weight of parts, help the reduction of whole locomotive gearbox deadweight, and because the lining 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 a structural representation of the present utility model.
Embodiment
As shown in the figure, this rail vehicles gearbox is made up of the pedestal 1 of monomer cast nylon material and the lining 2 of oil-containing nylon material with bearing support, and lining is embedded in the mounting hole on the pedestal.
Claims (1)
1, a kind of rail vehicles gearbox bearing support, it is characterized in that: it includes a pedestal of being made by the monomer cast nylon material (1), has mounting hole on pedestal, is embedded with the lining of being made by the oil-containing nylon material (2) in mounting hole.
