Abstract
Description
Technical Field
[0001] The invention relates to a support and limiting mechanism for a rotating component of a cone crusher, and belongs to the technical field of cone crushers. Background Art
[0002] Cone crusher is one of the main crushing equipment in mining and sand and gravel aggregate industry. It is mainly used for crushing materials with medium hardness or above. It is widely used in metal mines such as iron ore, molybdenum ore, gold mine, copper mine, and sand and gravel aggregate fields such as real estate, infrastructure, water conservancy and hydropower. It can be used for medium and fine crushing and has the characteristics of large crushing ratio, high output, good product particle shape, reliable operation, easy maintenance and low operating cost.
[0003] The rotating parts of the cone crusher mainly play a transmission role. Its outer diameter and inner hole are designed with an eccentric structure. When the outer diameter rotates around the fixed frame, the center line of the inner hole moves eccentrically, thereby driving the main shaft assembled in the inner hole to move eccentrically, realizing the change of the discharge port along the circumferential direction, thereby achieving the material crushing effect.
[0004] First, a large gear is mounted on the rotating component, providing power through gear transmission, creating rotational motion. Second, the rotating component is in constant rotation during operation, generating friction on the supporting surface. Wear and heat generation should be minimized. Furthermore, the cone crusher utilizes a vertical transmission method, using straight or spiral bevel gears. This creates a vertical upward separation at the gear meshing point. To ensure balanced and stable operation of the rotating component, a copper stopper is designed above the force-bearing area of the rotating component. This stopper is connected to a stationary protective shield, and its lower surface generates friction with the rotating component, minimizing wear and heat generation. Summary of the Invention
[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a support and limiting mechanism for the rotating components of a cone crusher, which provides support for the vertical gravity action of the rotating components of the cone crusher, provides a limit for the local vertical upward force component, and provides oil channels on the contact surfaces of the mutually moving components, thereby minimizing friction and wear and reducing heat generation.
[0006] The present invention is achieved through the following technical solutions: a support and limiting mechanism for the rotating parts of a cone crusher, characterized in that it includes a copper plate for support and a limiting copper block for limiting, the copper plate is installed on a frame, a lubricating oil channel I is provided on the surface of the copper plate, a wedge-shaped oil groove I is opened on one side of the lubricating oil channel I, the rotating part is directly supported on the copper plate, the limiting copper block is arranged above the rotating part, the limiting copper block is installed on a fixed protective cover, the lower surface of the limiting copper block is designed with a lubricating oil channel II and a wedge-shaped oil groove II, the inner hole of the rotating part is provided with an arc-shaped oil channel, and the lubricating oil can enter the copper plate and the limiting copper block through the arc-shaped oil channel.
[0007] The lubricating oil is driven by the motor to pump the lubricating oil, and then enters the radiator after passing through the filter, ensuring that the cooled lubricating oil enters the lubricating oil circuit composed of the crusher's lubricating oil channel I, lubricating oil channel II and the arc oil channel. The lubricating oil circuit is equipped with an oil inlet temperature sensor, an oil inlet flow sensor, a return oil temperature sensor and a return oil flow sensor.
[0008] The part of the rotating component supported on the copper disk is made of cast steel, which has greater hardness and strength than the copper disk.
[0009] The outer diameter and inner hole of the rotating component are designed to be eccentric. The outer diameter rotates around the fixed frame, thereby driving the main shaft matched with the inner hole to perform eccentric movement, realizing the rotating cone installed on the main shaft to perform rotary swing movement, completing the crushing function of the crusher.
[0010] The copper plate and the limiting copper block are lubricated by circulating thin oil, which can lubricate the friction surface on the one hand and take away the heat generated by friction through the continuously circulating lubricating oil on the other hand.
[0011] The invention has the beneficial effect of ensuring that the friction surfaces are fully lubricated during the operation of the crusher. The design of the lubricating oil channel allows lubricating oil to enter the friction surface, reducing the friction coefficient and thus reducing frictional heat, thereby increasing the service life of wearing parts and reducing heat dissipation in the lubrication station.

[0026] like Figures 1 to 11 The support and limiting mechanism for the rotating components of a cone crusher is shown, characterized by comprising a copper disc 1 for support and a limiting copper block 2 for limiting. The copper disc 1 is mounted on a frame 3, and a lubricating oil channel I4 is provided on its surface. A wedge-shaped oil groove I5 is provided on one side of the lubricating oil channel I4. The rotating component 6 is directly supported on the copper disc 1, and the limiting copper block 2 is positioned above the rotating component 6. The limiting copper block 2 is mounted on a stationary protective cover 7. The lower surface of the limiting copper block 2 is designed with a lubricating oil channel II8 and a wedge-shaped oil groove II9. The inner bore of the rotating component 6 is provided with an arcuate oil channel, through which lubricating oil can enter the copper disc 1 and the limiting copper block 2. The copper disc 1 is used to support the rotating component 6 of the cone crusher, and the limiting copper block 2 is used to limit the component. The lubricating oil channels I4 and II8 designed on the copper disc 1 and the limiting copper block 2 ensure that the friction surfaces are fully lubricated during the operation of the crusher. At the same time, copper disc 1 and stopper copper block 2, as wearing parts, minimize wear on rotating component 6, effectively reducing crusher maintenance costs. The design of the lubrication channels on copper disc 1 and stopper copper block 2 allows lubricant to enter the friction surface, reducing the friction coefficient and thus frictional heat generation, thereby extending the service life of wearing parts and reducing heat dissipation in the lubrication station.
[0027] The lubricating oil is driven by the motor to pump the lubricating oil, and then enters the radiator after passing through the filter, ensuring that the cooled lubricating oil enters the lubricating oil circuit composed of the lubricating oil channel I4, lubricating oil channel II8 and the arc oil channel of the crusher. The lubricating oil circuit is equipped with an oil inlet temperature sensor, an oil inlet flow sensor, a return oil temperature sensor and a return oil flow sensor. This ensures that the oil inlet of the crusher is normal. At the same time, the operating status of the crusher can be judged by the temperature and flow parameters of the return oil. The control system can make reminders, alarms and shutdown actions, realizing intelligent control of the lubrication system. The principle of the lubrication system is as follows: Figure 12 shown.
[0028] The part of the rotating component 6 supported on the copper disk 1 is made of cast steel, which has greater hardness and strength than the copper disk 1. Therefore, the copper disk 1 is used as a wearing part and the rotating component 6 does not need to be replaced.
[0029] The outer diameter and inner hole of the rotating component 6 are designed to be eccentric. The outer diameter rotates around the fixed frame 3, thereby driving the main shaft 10 that cooperates with the inner hole to perform eccentric movement, realizing the rotating cone installed on the main shaft 10 to perform a rotary swing movement, completing the crushing function of the crusher. One end of the horizontally placed transmission shaft of the rotating component 6 is directly driven by the electric motor, and the other end is installed with a small gear. The large gear is driven by the rotation of the small gear. The application of the bevel gear can realize vertical transmission. The transmission of the present invention adopts a vertical transmission method. The rotating component 6 is subjected to a vertical upward force component. The limiting copper block 2 just above the force-bearing part and the wedge-shaped oil groove II9 designed on the lower surface of the limiting copper block 2 facilitate the lubricating oil to enter the friction surface to form an oil film. Because the rotating component 6 is subjected to its own vertical downward gravity and the vertical upward force component of the small gear, the rotating component 6 is supported and limited in the vertical direction.
[0030] The copper plate 1 and the limiting copper block 2 are lubricated with circulating thin oil, which can lubricate the friction surface on the one hand and take away the heat generated by friction through the continuously circulating lubricating oil on the other hand.
