The thickness of wheel body is improve by adopting above-mentioned technical proposal, the setting of pressure step, by escape and oilhole
Perforate end opens up processing from resistance to splenium, and pressure step plays buffering machining stress, substantially reduces processing escape and oilhole pair
The rigid load of gear, and in order to further improve the structural strength and structural stability of pressure step, and then resistance to
Present a theatrical performance as the last item on a programme arrange on rank and perisporium and the connection of wheel body end face resistance to splenium, due to the arcuate structure that resistance to splenium is 45 °, the meeting in stress
The very strong internal force for being used to offset external force is produced, so ensure that its stress is indeformable.
In order to realize that escape possesses the ability for storing oil, and then connect by the one end open alignment escape of oilhole and with which
It is logical, and the structure of escape can also improve the structural strength at the one end open of oilhole.
Semicircular arc wall in the middle of escape as stores oily end wall, and the first beveled walls being placed on pressure step play slow
The purpose that lubricating oil in oil hole flows out flow velocity is rushed, prevents its flow velocity too fast, it is impossible to which realization carries out the purpose of oiling to escape, and
The second beveled walls being placed on wheel shaft play the purpose that lubricating oil can flow back from wheel shaft.
The structure design of escape:The combination of semicircular arc wall and the first beveled walls and the second beveled walls, semicircular arc wall
Play support and offset the ability of the first beveled walls and external force suffered by the second beveled walls, and the first beveled walls and the second beveled walls sheet
Body possesses very strong voltage endurance capability.
This utility model is further arranged to:The oilhole is oblique and oilhole inwall constitutes taper microgroove with teeth.
Play and alleviate when lubricating oil is injected to oilhole due to stream by adopting above-mentioned technical proposal, the setting of tooth taper microgroove
Speed is too fast and cause the oilhole inwall can not immersion oil completely.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is G portions of the present utility model enlarged drawing.
Specific embodiment
Embodiment of the present utility model is described further referring to figs. 1 to Fig. 2.
