[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0028] like Figure 1 As shown, a slider coupling proposed by the utility model comprises an intermediate shaft 1, both ends of the intermediate shaft 1 are provided with a first connecting flange 2; a jaw sleeve 3, one end of the jaw sleeve 3 is provided with a second connecting flange 4, the jaw sleeve 3 is mounted on the intermediate shaft 1 through the second connecting flange 4 and the first connecting flange 2, and the jaw sleeve 3 can allow a certain axial and radial displacement; a pin 5, both ends of the pin 5 are provided with a connecting slider 6, the pin 5 is connected to the inner wall of the jaw sleeve 3 through the connecting slider 6, a flat head 7 is provided on the pin 5, and the cooperation between the pin 5 and the jaw sleeve 3 enables the coupling to adapt to a certain degree of displacement change, while ensuring the continuity and stability of torque transmission; a connecting oil pipe 8, the connecting oil pipe 8 is arranged on the contact surface between the jaw sleeve 3 and the first connecting flange 2, the connecting oil pipe 8 is connected to the oil storage chamber 13, and is used to provide lubrication function for the coupling, and the lubricating oil can be transported from the oil storage chamber 13 to the coupling through the connecting oil pipe 8, so as to reduce friction and wear and improve the operation efficiency and service life of the coupling.

[0029] Preferably, the connecting slider 6 is a component made of ZCuSn10P1 tin bronze, which has excellent mechanical properties and wear resistance and is suitable for manufacturing parts that work under heavy loads and are subject to strong friction.

[0030] Preferably, the jaw bushing 3 is a component made of 30Cr2Ni2Mo alloy quenched and tempered steel, which has high strength, good mechanical properties, certain toughness and wear resistance, and is therefore suitable for manufacturing engineering parts that need to withstand large loads and stresses.

[0031] In this embodiment, the first connecting flange 2 is provided with a plurality of connecting holes 1, and the second connecting flange 4 is provided with a plurality of connecting holes 2 matching the connecting holes 1. The first connecting flange 2 is installed on the second connecting flange 4 through the connecting holes 1 and 2 and is locked through the connecting unit.

[0032] In this embodiment, the connecting unit includes a stud 9, which extends through connecting hole one and into connecting hole two. The end of the stud 9 is locked by a nut 10. When the nut 10 is tightened, a pre-tightening force is generated on the stud 9, so that the first connecting flange 2 and the second connecting flange 4 fit tightly together.

[0033] In this embodiment, end face positioning teeth are provided on the outer end faces of the first connecting flange 2 and the second connecting flange 4. Due to the presence of the end face positioning teeth, the first connecting flange 2 and the second connecting flange 4 can form a closer contact when connected, which enables the torque to be more evenly distributed during the transmission process.

[0034] In this embodiment, a receiving groove is opened on the outer wall of the first connecting flange 2 and the second connecting flange 4, and an end face tooth sealing ring 11 is arranged in the receiving groove. The end face tooth sealing ring 11 is tightly embedded in the receiving groove and forms a tight fit with the outer wall of the connecting flange, thereby effectively preventing the leakage of lubricating oil.

[0035] Preferably, the end face tooth seal ring 11 is made of nitrile rubber, which has excellent oil resistance, wear resistance, heat resistance and adhesion.

[0036] In this embodiment, an oil injection channel 12 is provided on the jaw sleeve, a first end of the oil injection channel is connected to the outside, and the other end of the oil injection channel 12 is connected to the connecting oil pipe 8, and the operator can add lubricating oil to the coupling as needed to maintain its good working condition and performance. The addition of lubricating oil can reduce friction and wear, and improve the operating efficiency and life of the coupling.

[0037] In this embodiment, a plug 14 is provided on one end of the oil storage chamber away from the connecting oil pipe 8 .

[0038] The use process and principle of the utility model are as follows: when in use, the first connecting flange 2 is installed together with the connecting hole 2 on the second connecting flange 4 through the connecting hole 1, and locked with the stud 9 and the nut 10. Due to the presence of the end face positioning teeth, the first connecting flange 2 and the second connecting flange 4 can form a closer contact when connected; through the oil injection channel on the jaw sleeve, add an appropriate amount of lubricating oil into the oil storage chamber. The lubricating oil is transported to the inside of the coupling through the connecting oil pipe 8 to provide lubrication for the coupling; when the coupling is running, the pin 5 moves freely in the jaw sleeve 3 through the connecting slider 6 to adapt to the axial and radial displacement changes. At the same time, the torque is stably transmitted through the first connecting flange 2, the pin 5 and the second connecting flange 4; regularly check the amount of lubricating oil in the oil storage chamber and replenish it as needed. At the same time, check the fastening of each component to ensure the normal operation of the coupling. In summary, the slider coupling has excellent performance in practical applications due to its excellent displacement adaptability, torque transmission stability, lubrication function and material durability, and can effectively improve the operating efficiency and stability of the equipment.
