Abstract
The utility model provides a transmission shaft for a gear box and in particular relates to a vertically-assembled transmission shaft in the gear box. The transmission shaft for the gear box is mainly characterized by comprising a shaft body and more than two bearings which are arranged on the shaft body, wherein more than two blades are arranged on the shaft body and positioned below upper bearings; and a curved surface of each blade has a structure of pushing lubricating oil upwards or throwing out the lubricating oil. By adoption of the transmission shaft for the gear box, the defect that the upper bearings are lack of oil because the lubricating oil in the gear box lubricates lower bearings and cannot lubricate the upper bearings when the transmission shaft in the prior art rotates is overcome. By adding the blades below the upper bearings of a gear shaft, engine oil in the gear box is thrown to the upper bearings according to a blade inclined surface principle when the gear shaft rotates, after being lubricated, the upper bearings cannot be lack of the oil and cannot be damaged, and the service life of equipment is prolonged.
Description
Technical field
The utility model belongs to a kind of transmission device of mechanical field
,Be specifically related to the transmission shaft of vertical assembling in a kind of gear-box.
Background technique
In the prior art, the structure of the transmission shaft of vertical assembling is in the gear-box, respectively be equipped with up and down two with upper bearing (metal) at transmission shaft, lubricant oil when transmission shaft rotates in the gear-box can only lubricate the bearing of lower end, can not lubricate the bearing to the upper end, cause upper end bearing oil starvation, lack for a long time under the lubricating status and work, the as easy as rolling off a log damage of bearings that causes.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of can be thrown the lubricant oil in the gear-box on the bearing of upper end, guarantee the gear-box transmission shaft that the upper end bearing can obtain lubricating.
The technical solution of the utility model comprises axis body and the plural bearing that is loaded on the axis body, and the axle below the bearing of upper end is equipped with blade, and described blade is more than 2.
Blade described in the utility model is curved-surface structure.
The structure of the curved-surface structure of described blade for lubricant oil upwards being promoted or dishes out.
The utility model has installed blade additional below the bearing of gear shaft upper end after, gear shaft utilizes the principle on blade inclined-plane when rotating, machine oil in the gear-box is thrown on the bearing of upper end, and the upper end bearing just can owing to oil starvation causes damage of bearings, not increase service life of equipment after obtaining lubricating.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Among Fig. 1, the bearing that is loaded on the axis body 1 has upper bearing (metal) 2, lower bearing 3.On the axis body 1 that upper bearing (metal) 2, lower bearing are 3 blade 4 is housed, blade 4 is more than two, is symmetrical arranged or evenly distributes.The structure of the curved surface of blade 4 for lubricant oil upwards being promoted or dishes out.5 is gear among the figure.
Claims (3)
1. gear-box transmission shaft is characterized in that: comprise axis body and be loaded on plural bearing on the axis body, the axle below the bearing of upper end is equipped with blade, and described blade is more than 2.
2. a kind of gear-box transmission shaft according to claim 1, it is characterized in that: described blade is curved-surface structure.
3. a kind of gear-box transmission shaft according to claim 2 is characterized in that: the structure of the curved-surface structure of described blade for lubricant oil upwards being promoted or dishes out.
