AI Technical Summary
The existing gear shafts lack self-lubricating function, resulting in high friction, severe wear, and easy damage to the gears after long-term use.
A self-lubricating gear shaft was designed. By opening oil grooves and oil guide holes in the inner wall of the shaft, lubricating oil is used to lubricate the gear surface. The lubricating oil is effectively utilized and sealed by baffles and sealing grooves.
It reduces friction during gear meshing, reduces gear wear, and extends service life.

Description
TECHNICAL FIELD
[0001] The utility model belongs to gear shaft technical field relates to a gear shaft especially relates to a self -lubricating gear shaft. BACKGROUND
[0002] Gear shaft is the core component in mechanical transmission system, it fuses as one the function of gear and shaft, through supporting gear and rotating together, realizes the transmission of motion, torque or bending moment.
[0003] The gear shaft on the market mostly does not have self -lubricating function, the meshing operation of gear under the long time use of gear shaft, the friction of gear is greater, makes the wear and tear of gear to aggravate, easily damaged, therefore, design a kind of self -lubricating gear shaft has important significance. SUMMARY
[0004] The utility model discloses a kind of self -lubricating gear shafts to the above problems existing in prior art.
[0005] The utility model discloses a kind of self -lubricating gear shafts, it is characterized in that, including shaft body and the gear piece of integration with shaft body, the oil groove is set in the inner wall of shaft body, the oil groove is set in the oil guide hole of surface intercommunication with gear piece, the surface of shaft body is connected with baffle with screw thread, the sealing groove that gear piece is set on is provided with the movable baffle, and sealing groove is interconnected with oil guide hole.
[0006] In the above-mentioned self -lubricating gear shaft, the limit board is fixedly arranged on the shaft body, the reinforcing plate is fixedly arranged on the limit board, and the reinforcing plate is fixedly connected with the gear piece on one side.
[0007] In the above-mentioned self -lubricating gear shaft, the oil groove side wall is set with oil injection hole, and the sealing bolt is arranged on the oil injection hole.
[0008] Compared with prior art, the self -lubricating gear shaft is lubricated to gear piece surface, so that the friction force received when gear piece meshing operation is reduced, and gear loss can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 2 It is the cross-sectional structure schematic diagram of the self -lubricating gear shaft.
[0011] In the drawing, 1, shaft body;2, gear piece;3, oil groove;4, oil guide hole;5, baffle;6, sealing groove;7, limit board;8, reinforcing plate;9, oil injection hole;10, sealing bolt. DETAILED DESCRIPTION
[0012] The utility model discloses the specific embodiment below and further describes the technical scheme of the utility model with the drawings, but the utility model is not limited to these embodiments.
[0013] As Figs. 1-2 The utility model discloses a self-lubricating gear shaft, including shaft body 1 and gear piece 2 with shaft body 1, the oil groove 3 is seted up in the inner wall of shaft body 1, the oil groove 3 is seted up in the oil guide hole 4 that communicates with the surface of gear piece 2, the surface of shaft body 1 is connected with the baffle 5 of screw thread, the sealing groove 6 that the baffle 5 moves is seted up on gear piece 2, and the sealing groove 6 is communicated with the oil guide hole 4, by adding lubricating oil liquid in the oil groove 3, lubricating oil liquid can flow to the surface of gear piece 2 through the oil guide hole 4, and the surface of gear piece 2 is lubricated, so that when gear piece 2 engages and runs, the friction force that is received is reduced, can reduce the gear loss, the surface baffle 5 of shaft body 1 can rotate and adjust, when gear piece 2 is not used, can rotate the baffle 5, and the baffle 5 can seal the oil guide hole 4, avoid oil waste, and the surface of baffle 5 is in close contact with the sealing groove 6, to prevent oil leakage.
[0014] Preferably, the limiting plate 7 is fixedly arranged on the shaft body 1, and the reinforcing plate 8 is fixedly arranged on the limiting plate 7, and one side of the reinforcing plate 8 is fixedly connected with the gear piece 2.
[0015] Preferably, the oil injection hole 9 is arranged on the side wall of the oil groove 3, and the sealing plug 10 is arranged on the oil injection hole 9, the oil injection hole 9 is used for adding lubricating oil liquid, and the sealing plug 10 seals the oil injection hole 9 to prevent liquid leakage.
[0016] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
