Abstract
The utility model relates to a wear-resisting rolling-over shaft of a dumper. A rolling-over shaft seat (4) is arranged under a big carriage chassis (5) and is used for lifting a big carriage; the wear-resisting rolling-over shaft is characterized in that a rolling-over shaft main body (1) is arranged in the rolling-over shaft seat (4), processing surfaces at two ends of the rolling-over shaft main body (1) are provided with inner cushion sleeves (2), and the inner cushion sleeves (2) are externally provided with steel sleeves (3). The processing surfaces at the two ends of the rolling-over shaft are additionally provided with the nylon sleeves with oil grooves, the nylon sleeves are then sleeved with the steel sleeves, thus the lubricating quality between the rolling-over shaft and the steel sleeves can be increased, the abrasion between thea steel shaft and the steel sleeves can be relieved, the lifting is flexible, the dustproof performance is good, the after-scale service cost is reduced, the transportation efficiency and the economic benefit of a user are increased, and safety and reliability are realized; the wear-resisting rolling-over shaft disclosed by the utility model is adaptives to a carriage manufacturing process in the uploading industry of the dumper.
Description
Technical field
The utility model belongs in dump truck van manufacture and fills industry, is specifically related to the wear-resisting trip shaft of a kind of dumping car.
Background technology
On dumping car, fill at present industry when manufacturing dumping car trip shaft assembly, great majority all adopt the method for the equipped steel bushing of steel axle to carry out the upset of large railway carriage or compartment, rigidity friction between steel and steel, add dust effect, the rate of wear is fast, damage frequency is high, has not only increased the after service cost of enterprise, and has brought very large trouble and economic loss to vehicle user.
Summary of the invention
The purpose of this utility model is for avoiding prior art not enough, providing a kind of dumping car wear-resisting trip shaft.
For achieving the above object, the technical scheme that the utility model is taked is: the wear-resisting trip shaft of a kind of dumping car, upset axle bed (4) is located under large railway carriage or compartment underframe (5), for the lifting of large railway carriage or compartment, it is characterized in that: trip shaft main body (1) is located in upset axle bed (4), on the finished surface of trip shaft main body (1) two, be provided with interior cushion cover (2), the outer steel bushing (3) that is provided with of interior cushion cover (2).
Described interior cushion cover (2) is with oiling groove, and the oilhole of oiling groove and interior cushion cover (2) coordination connect.
Described interior cushion cover (2) is made by nylon.
The effect that the utility model is useful is: on the finished surface of trip shaft two, increase the nylon jacket with oil groove, steel bushing is installed again, can improve the lubricating quality of trip shaft and steel bushing, slow down the wearing and tearing between steel axle and steel bushing, and lifting is flexible, anti-dust performance is good, has reduced after service cost, improve user's conveying efficiency and economic benefit, and safe and reliable.Be adapted to fill on dumping car industry envelope manufacturing process.
