SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome above-mentioned problem, and provide an automatic realize lubricated gear, show and improve lubricated radiating effect, need not artificial paining.
The technical scheme of the utility model is that:
a gear, including the gear body that has shaft hole and teeth of a cogwheel, its characterized in that: a plurality of radially extending sliding grooves are uniformly formed in the end face of one side of the gear body around the shaft hole, a sliding part is arranged in each sliding groove in a sliding mode, each sliding part comprises a first protrusion, a second protrusion, a connecting arm and a sliding block, the connecting arm extends in the direction of the sliding groove, the first protrusion and the second protrusion are connected to the inner end and the outer end of the connecting arm respectively, and the sliding block is fixed to the lower end face of the connecting arm and arranged in the sliding groove in a sliding mode; the upper end surface of each first bulge is also provided with a concave arc ring groove, the arc ring grooves on all the first bulges can be spliced together to form an annular spring groove, and an annular spring is arranged in the spring groove; the second arch is that the circular arc is cyclic annular and all the protruding amalgamation of second is the ring form, the holding tank has been seted up to the bellied lower terminal surface of second, the embedded oil absorption piece that is equipped with of holding tank, the last absorption of oil absorption piece has lubricating oil, and the second arch can outwards slide along with the slider and make oil absorption piece and teeth of a cogwheel contact from this.
Borrow by above-mentioned structure, the utility model discloses can realize self-lubricate according to the current rotational speed of gear, drive whole slider along with the spout footpath with the help of the centrifugal force that the high-speed rotatory production of gear body is outside smooth to oil absorption piece and the contact of teeth of a cogwheel through the second bellying play lubricated radiating effect to the gear tooth, need not artificially to shut down and paint repeatedly. When the oil suction block rotates at a low speed or stops rotating, the annular spring contracts to drive the sliding piece to move inwards in the radial direction, so that the oil suction block is separated from the gear teeth, and excessive lubrication is avoided.
Further, in the gear of the present invention, the first protrusions are circular arc ring-shaped and all the first protrusions can be joined into a circular ring shape.
Further, in the gear of the present invention, the upper end surface of the circular arc ring groove is provided with a blocking piece for blocking the separation of the annular spring.
Further, in the gear of the present invention, the number of the sliding grooves is not less than 3.
Further, in the gear, the protruding up end of second is equipped with the oil filler point that is linked together with the holding tank, is convenient for directly follow the up end oiling.
The utility model has the advantages that:
the utility model discloses simple structure, reasonable in design, through, can take the degree of radially sliding of the slider of oil absorption piece according to the current rotation rate adaptive control of gear in order to realize self-lubricate. When the oil absorption block rotates at a high speed, the oil absorption block is in contact with the gear teeth of the gear to be automatically lubricated by means of centrifugal force generated by high-speed rotation of the gear, so that the surface of the gear is not easy to wear, the heat dissipation performance is good, the service life is longer, manual shutdown smearing is not needed, and the lubrication efficiency is improved. When the oil suction block rotates at a low speed or stops rotating, the oil suction block is retracted and returned through the annular spring, so that the oil suction block is separated from the gear teeth, and the phenomenon of excessive lubrication cannot occur.

Detailed Description
The present invention will now be further described with reference to the accompanying drawings:
referring to fig. 1, fig. 2 and fig. 3, the gear of this embodiment includes a gear body 1 with a shaft hole and gear teeth, a plurality of radially extending sliding grooves 2 are uniformly arranged on a side end face of the gear body 1 around the shaft hole, and the number of the sliding grooves 2 is not less than 3. A sliding part is arranged in each sliding groove 2 in a sliding way. Specifically, every the slider includes first arch 3, second arch 4, linking arm 5 and slider 6, linking arm 5 extends just along 2 directions of spout first arch 3, the protruding 4 of second are connected respectively in the inner and the outer end of linking arm 5, slider 6 fixes terminal surface and slides and set up in spout 2 under linking arm 5.
The first bulges 3 are in the shape of circular arc rings, and all the first bulges 3 can be spliced into a circular ring shape; the upper end surface of each first bulge 3 is also provided with a concave arc ring groove 7, the arc ring grooves 7 on all the first bulges 3 can be spliced together to form a circular spring groove, and an annular spring 8 is arranged in the spring groove. The upper end surface of the circular arc ring groove 7 is also provided with a baffle piece 11 for stopping the annular spring 8 from separating.
The second protrusion 4 is circular arc-shaped and all the second protrusions 4 can be spliced into a circular ring shape, the accommodating groove is formed in the lower end face of the second protrusion 4, an oil absorption block 9 is embedded in the accommodating groove, lubricating oil is adsorbed on the oil absorption block 9, and the second protrusion 4 can slide outwards along with the sliding block 6 to enable the oil absorption block 9 to be in contact with the gear teeth. The upper end face of the second bulge 4 is provided with an oil filling hole 10 communicated with the accommodating groove.
The working principle of the structure is as follows: the gear body 1 forms centrifugal force when rotating; when the gear body 1 rotates to reach a certain rotating speed, the generated centrifugal force is enough to overcome the elastic potential energy of the annular spring 8, so that the whole sliding piece slides outwards along with the sliding groove 2, the oil suction block 9 at the second bulge 4 is driven to be in contact with the gear teeth, the lubricating oil lubricates the gear teeth, the high temperature generated by the gear operation is further reduced, and the use safety and reliability are effectively improved; when the rotation speed of the gear is slowed down or stopped, the annular spring 8 pulls the first bulge 3 to contract inwards, the sliding block 6 slides inwards along the sliding groove 2, and the oil suction block 9 of the second bulge 4 is separated from contact with the gear teeth.
