[0020] See also Figure 1-Figure 5 The utility model provides the following technical solutions: a rust-proof and wear-resistant gear, comprising a gear body 1, a mounting hole is provided in the middle of the gear body 1, an annular oil storage groove 2 is provided on the surface of the gear body 1, a concave platform 3 is provided on the top of the gear body 1 located at the annular oil storage groove 2, an annular column 4 is formed between the annular oil storage groove 2 and the middle of the gear body 1, an oil sealing cover 5 is installed on the top of the annular oil storage groove 2, an oil sealing assembly 6 is installed in each tooth groove of the gear body 1, and a plurality of oil delivery channels 7 connected with the corresponding oil sealing assemblies 6 are provided in the annular oil storage groove 2.

[0021] The oil sealing cover 5 comprises a cover body 51, an opening 52 is formed in the middle of the cover body 51, a first sealing ring 53 is installed at the bottom end of the cover body 51 at the opening 52, a second sealing ring 55 is also installed at the bottom end of the cover body 51, a first annular sealing groove 54 is formed on the outer wall of the annular column 4 and the inner wall of the first sealing ring 53, a second annular sealing groove 56 is formed on the outer wall of the second sealing ring 55 and the top of the annular oil storage tank 2, the cover body 51 is installed on the surface of the concave platform 3, and the first sealing ring 53 is sleeved. A first O-ring 8 is installed on the outside of the annular column 4 and in the corresponding first annular sealing groove 54, a second sealing ring 55 is sleeved in the annular oil storage groove 2 and in the corresponding second annular sealing groove 56 a second O-ring 9 is installed, an oil injection assembly 10 is installed on the top of the cover body 51, the size of the cover body 51 matches the size of the recessed platform 3, the inner diameter of the first sealing ring 53 matches the diameter of the annular column 4, and the diameter of the second sealing ring 55 matches the inner diameter of the annular oil storage groove 2.

[0022] Specifically, after injecting oil into the annular oil storage tank 2, the cover body 51 is installed in the recessed platform 3 and the first sealing ring 53 is sleeved on the outside of the annular column 4 and the second sealing ring 55 is sleeved in the annular oil storage tank 2. The first O-ring 8 and the second O-ring 9 installed in the first annular sealing groove 54 and the second annular sealing groove 56 can effectively improve the sealing between the cover body 51 and the annular oil storage tank 2 to avoid oil leakage during use of the gear.

[0023] In this embodiment, the oil sealing assembly 6 includes an installation cavity 61 opened in the gear body 1, the oil delivery channel 7 is connected to the installation cavity 61, a telescopic rod 62 is installed in the installation cavity 61, one end of the telescopic rod 62 is fixedly connected to a sealing ball 63, a spring 64 is sleeved on the outside of the telescopic rod 62, and the two ends of the spring 64 are respectively connected to the sealing ball 63 and the installation cavity 61, an oil outlet that passes through the installation cavity 61 is opened in the tooth groove of the gear body 1, the oil outlet is opposite to the sealing ball 63, and part of the sealing ball 63 is exposed in the tooth groove of the gear body 1.

[0024] Specifically, when the gear is meshed with other gears, the tooth marks of the other gears are meshed with the tooth grooves of the gear body 1 and squeeze the blocking ball 63. At this time, the blocking ball 63 drives the telescopic rod 62 to move inward and squeeze the spring 64, so that the oil in the annular oil storage tank 2 enters the installation cavity 61 through the oil delivery channel 7 and flows out through the oil outlet, thereby lubricating the gear and effectively improving the wear resistance of the gear. Moreover, since oil flows out of each tooth groove when the gears are meshed, the gear body 1 can be better lubricated and the outflowing oil can effectively prevent the gear body 1 from rusting.

The fixing columns 11 are inserted and connected with the fixing holes 12, and fixing bolts 13 are threadedly connected in the fixing screw holes. When the cover body 51 is installed in the recessed platform 3, the bottom end of the first sealing ring 53 is in contact with the bottom end of the annular oil storage groove 2, and the top end of the annular column 4 is in the same horizontal plane as the top end of the cover body 51.

[0026] Specifically, the fixing holes 12 and the fixing columns 11 are provided so that the staff can quickly position and install the cover 51 . After the cover 51 is installed, the fixing bolts 13 can be used to fix the cover 51 , thereby completing the assembly of the gear.

[0027] In this embodiment, the oil filling assembly 10 includes two fixed blocks 101 fixedly installed on the top of the cover body 51, and a one-way valve 102 is embedded in the fixed block 101.

A rubber plug 104 is installed on the top of the oil inlet groove 103.

[0028] Specifically, when it is necessary to inject oil into the annular oil storage tank 2, the staff only needs to pierce the rubber plug 104 through the needle of the syringe to inject oil into the oil inlet groove 103. Under the action of the one-way valve 102, the oil enters the annular oil storage tank 2 through the one-way valve 102, and the oil in the annular oil storage tank 2 will not flow out through the one-way valve 102. This oil filling method is simple and convenient, and the staff does not need to remove the oil sealing cover 5 before filling the oil, which effectively improves the oil filling efficiency.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
