Abstract
The invention discloses a bearing pack for an electric flat carriage. The bearing pack is provided with a bearing pedestal, a bearing is arranged in the bearing pedestal, a through cover is arranged at the left end of the bearing pedestal, an axle hole is formed in the through cover, and a blank cap is arranged at the right end of the bearing pedestal. The bearing pack for the electric flat carriage is characterized in that an oil nozzle mounting hole is formed in the blank cap, and an oil nozzle is arranged in the oil nozzle mounting hole. According to the bearing pack for the electric flat carriage, the oil nozzle is arranged on the blank cap, the bearing can be lubricated conveniently, a rolling body of the bearing can be prevented from getting stuck, and the bearing pack can be used stably and is mainly applied to the electric flat carriage.
Description
Technical field
The present invention relates to electric flat carriage technical field, especially a kind of electric flat carriage bearing pack.
Background technique
Flatcar is mainly used in transporting the larger goods of steel, timber, automobile, machinery equal-volume or weight, also can transport other goods by shipping container.Flatcar can also adapt to national defence needs, loads various military hardware.The flatcar that wild wall is housed also can be used to the loose goods such as loading for ore, sandy soil, rock ballast.The flatcar of Chinese Railway accounts for 12% of lorry sum.Flatcar is not because having fixing sidewall and end wall, and pretending and carried on a shoulder pole by each joist support of underframe completely by normal load onboard and longitudinal loading, is typical underframe bearing structure.China's designed, designed and manufactured multiple flatcar, divide from structure, mainly contain flat be with board-like two kinds of movable wall.
Tradition flatcar bearing pack has bearing support, and bearing support is built with bearing, and the left end of bearing support is equipped with logical lid, and logical covering has axis hole, and the right-hand member of bearing support is equipped with stifle.Operationally, often there is the stuck phenomenon of rolling element in the bearing support of this conventional construction, uses extremely unstable.Therefore, design a kind of electric flat carriage bearing pack that can solve the problem well to be extremely necessary.
Summary of the invention
Object of the present invention is improved for above-mentioned the deficiencies in the prior art exactly, provides a kind of electric flat carriage bearing pack.
Concrete scheme of the present invention is: the bearing pack for conventional electric flatcar is improved, and it has bearing support, and bearing support is built with bearing, and the left end of bearing support is equipped with logical lid, and logical covering has axis hole, and the right-hand member of bearing support is equipped with stifle; It is characterized in that: described stifle has oil nozzle mounting hole, oil nozzle mounting hole is built with oil nozzle.
Bearing described in the present invention is selfaligning roller bearing.
The diameter D of logical lid described in the present invention is the diameter d of the axis hole of 185mm, Tong Gainei is 95mm.
Described in the present invention, logical lid and stifle are arranged on bearing support both sides by bolt and bullet pad.
The present invention is equipped with oil nozzle on stifle, can lubricate bearing easily, avoids the rolling element of bearing stuck, uses more stable.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present invention.
In figure: 1-bolt, 2-bullet pad, the logical lid of 3-, 4-axis hole, 5-bearing, 6-bearing support, 7-oil nozzle mounting hole, 8-oil nozzle, 9-stifle.
Embodiment
Below in conjunction with accompanying drawing, introduce the preferred embodiments of the present invention in detail.
See Fig. 1, the present invention has bearing support 6, and bearing support 6 is built with bearing 5, and the left end of bearing support 6 is equipped with logical lid 3, and logical lid 3 has axis hole 4, and 6 right-hand members of bearing support are equipped with stifle 9; Particularly: described stifle 9 has oil nozzle mounting hole 7, and oil nozzle mounting hole 7 is built with oil nozzle 8.
Bearing 5 described in the present embodiment is selfaligning roller bearing.
Described in the present embodiment, the diameter D of logical lid 3 is 185mm, and the diameter d of the axis hole 4 in logical lid 3 is 95mm.
Described in the present embodiment, logical lid 3 and stifle 9 are arranged on bearing support 6 both sides by bolt 1 and bullet pad 2.
