Description

Technical Field

[0001] This utility model relates to the field of cement chain technology, and in particular to a high-stability cement chain. Background Technology

[0002] In industrial settings such as cement production, chains, as critical transmission components, must operate for extended periods in harsh environments characterized by high dust levels, strong vibrations, and heavy loads. Their stability and durability directly impact production efficiency. Early chain sealing structures often employed single rubber rings or simple gaskets. Rubber rings, due to their poor oil resistance, easily swell and harden upon contact with lubricating oil, leading to seal failure. Gaskets, on the other hand, lacked structural adaptability and could not tightly fit the chain plate gaps, allowing cement dust to easily penetrate the mating gaps between the sleeve and the pin. Once inside, dust not only contaminates the internal lubricating medium and accelerates component wear but can also accumulate in the gaps, causing chain jamming, abnormal pitch, and in severe cases, even chain breakage, resulting in equipment downtime. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a highly stable cement chain. This solves the problem that the gasket cannot fit tightly with the gap between the chain plate due to insufficient structural adaptability, and cement dust can easily enter the fitting gap between the sleeve and the pin through the gap.

[0004] This utility model also provides a cement chain with the aforementioned high stability. The nitrile rubber O-ring is not only resistant to grease corrosion in the cement production environment, but its elasticity can also buffer the changes in sealing gap caused by chain plate vibration, ensuring long-term stable sealing effect. The dustproof gasket shares the pressure of the sealing ring through structural adaptability, avoiding excessive wear of a single sealing component. The synergistic system formed by the two, together with the high-strength carbon steel chain plate, alloy steel sleeve and pin, enables the chain to maintain operational reliability in complex environments with dust, vibration and high load, comprehensively improving the overall efficiency of cement production equipment.

[0005] This high-stability cement chain solution comprises: an inner chain plate, which is connected to the outer chain plate via a pin and a sleeve; a dustproof gasket and an O-ring seal are provided between the inner and outer chain plates; the dustproof gasket is fitted into the gap between the inner and outer chain plates; and the nitrile rubber O-ring seal, through these components, not only resists the erosion of grease in the cement production environment, but its elasticity also buffers the changes in sealing gap caused by chain plate vibration, ensuring long-term stable sealing performance; the dustproof gasket, through structural adaptability, shares the pressure of the seal, avoiding excessive wear of a single sealing component. The synergistic system formed by these two components, along with the high-strength carbon steel chain plate, alloy steel sleeve, and pin, enables the chain to maintain operational reliability even in complex environments with dust, vibration, and high loads, comprehensively improving the overall efficiency of cement production equipment.

[0006] According to the high-stability cement chain of this utility model, the O-ring seal and the dustproof gasket are used together to prevent cement dust from entering the gap between the sleeve and the pin, the inner chain plate and the outer chain plate. Through the above components, the service life of the chain is extended, wear is reduced, and the frequency of chain failure is also reduced.

[0007] According to the high-stability cement chain of this utility model, the outer chain plate and the inner chain plate are provided with through holes. The pin can pass through the outer chain plate and the inner chain plate through the through holes of the above components, connecting the two together. At the same time, with the cooperation of the sleeve and roller, a complete chain structure is formed.

[0008] According to the high-stability cement chain of this utility model, the pin shaft is provided with a insertion hole, through which positioning elements such as cotter pins can be inserted.

[0009] According to the high-stability cement chain of this utility model, the through holes on the inner chain plate and the outer chain plate are the same size. By ensuring that the through holes of the above components are the same size, it can be ensured that the pin can pass through the inner chain plate and the outer chain plate at the same time, avoiding assembly misalignment or uneven gap due to differences in hole diameter.

[0010] According to the high-stability cement chain of this utility model, the O-ring seal is closely attached to the outer surface of the inner chain plate, and the material of the O-ring seal is nitrile rubber. The above components enhance the sealing effect, adapt to the working environment, and extend the service life of the sealing components.

[0011] According to the high-stability cement chain of this utility model, both the inner chain plate and the outer chain plate are made of high-strength carbon steel. Through these components, the high-strength carbon steel has high tensile strength and yield strength, and can withstand the huge tensile force, impact force and periodic load on the chain when the cement production equipment is running.

[0012] According to the high-stability cement chain of this utility model, the sleeve is made of alloy steel and has a lubricating coating on the inner wall. It is clearance-fitted with the pin. Through the addition of alloying elements such as chromium, nickel, and molybdenum, the alloy steel of the above components has higher hardness, toughness and wear resistance than ordinary carbon steel.

[0013] Beneficial effects: Nitrile rubber O-rings are not only resistant to grease corrosion in the cement production environment, but their elasticity can also buffer changes in the sealing gap caused by chain vibration, ensuring long-term stable sealing performance; the dustproof gaskets share the pressure of the sealing rings through structural adaptability, avoiding excessive wear of a single sealing component. The synergistic system formed by the two, together with the high-strength carbon steel chain plates, alloy steel sleeves, and pins, enables the chain to maintain operational reliability in complex environments with dust, vibration, and high loads, comprehensively improving the overall efficiency of cement production equipment.

[0022] Reference Figure 1-4 This utility model embodiment of a high-stability cement chain includes: an inner chain plate 2, which is connected to an outer chain plate 1 via a pin 3 and a sleeve 5. The sleeve 5 is made of alloy steel and has a lubricating coating on its inner wall. It is clearance-fitted with the pin 3. Both the inner chain plate 2 and the outer chain plate 1 are made of high-strength carbon steel. The pin 3 is provided with a insertion hole 4, and the outer chain plate 1 and the inner chain plate 2 are provided with through holes 8. The through holes 8 on the inner chain plate 2 and the outer chain plate 1 are the same size. A dustproof gasket 6 and an O-ring seal 7 are provided between the inner chain plate 2 and the outer chain plate 1.

The O-ring seal 7 is tightly attached to the outer surface of the inner chain plate 2 and is made of nitrile rubber.

[0023] Specifically: When the chain is running, power is transmitted through the outer chain plate 1 and the inner chain plate 2. The pin 3, as the core connecting component, passes through the through holes 8 of the inner and outer chain plates 1. The pin 3, through its insertion holes 4 and in conjunction with positioning elements such as cotter pins, achieves a stable connection between the components, preventing loosening or axial movement during transmission. The sleeve 5 and the pin 3 are fitted with a clearance fit, providing flexible space for their relative rotation. The alloy steel material of the sleeve 5 gives it sufficient hardness to withstand the pressure transmitted by the rollers. The lubricating coating on the inner wall further reduces the coefficient of friction with the pin, reducing wear during relative movement. Simultaneously, in conjunction with the overall chain lubrication system, a low-friction state is maintained. For dust prevention and sealing, the dustproof gasket 6 between the inner chain plate 2 and the outer chain plate 1 is suitable for… The gap installation, combined with the nitrile rubber O-ring 7 tightly attached to the outer surface of the inner chain plate 2, forms a double barrier, effectively preventing cement dust from entering the gap between the sleeve 5, pin 3, and chain plate. The oil resistance and elasticity of the nitrile rubber ensure that the sealing ring can still maintain a tight fit when in contact with lubricating oil and slight vibration, preventing dust from acting as an abrasive and aggravating component wear. In addition, the inner and outer chain plates 1 are made of high-strength carbon steel, which has both rigidity and toughness, and can stably withstand the tension and impact during transmission. Together with the alloy steel sleeve 5 and pin 3, they form a high-strength load-bearing system, ensuring the structural stability of the chain under high load, ultimately achieving precise and efficient power transmission, and improving long-term operational stability in the cement production environment by reducing wear and failure.
