Description

Technical Field

[0001] The utility model relates to the technical field of crusher couplings, in particular to a high-calcium stone three-eight block crusher coupling installation structure. Background Art

[0002] A crusher is a piece of mechanical equipment used to crush materials, commonly used in industries such as mining, construction, chemicals, and metallurgy. It applies force to break large pieces of material into smaller particles or powder for subsequent processing and utilization. A crusher coupling is typically installed between the crusher's motor and the crushing body, connecting the motor and the crusher's rotating parts (such as the main shaft and gears) to transmit power and torque. The coupling's function is to ensure that the motor can smoothly drive the crusher's rotating components while reducing wear and energy loss caused by vibration and impact. Nylon rods are often used at the crusher coupling to reduce damage to the motor caused by vibration.

[0003] The existing nylon rod is usually inserted as a whole between the shafts of the steel sleeve. However, during long-term use, the nylon rod will expand and contract due to temperature changes, resulting in damage to the nylon rod, gaps in the connection, performance degradation, and affected torque transmission efficiency. Therefore, it is necessary to provide a high-calcium stone 38-piece crusher coupling installation structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a coupling installation structure for a high-calcium stone three-eight block crusher to solve the problem raised in the above background technology that the existing nylon rod is usually inserted between the shafts of the steel sleeve as a whole, but the nylon rod will expand and contract due to temperature changes during long-term use, resulting in damage to the nylon rod, gaps at the connection, performance degradation, and affected torque transmission efficiency.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a coupling installation structure for a high-calcium stone three-eight block crusher, comprising:

[0007] A coupling, comprising a steel sleeve, a first mounting groove, a shaft, and a second mounting groove;

[0008] The first mounting groove is provided on the inner side of the steel sleeve, the second mounting groove is provided on the outer side of the shaft, and the shaft is inserted into the steel sleeve;

[0009] An anti-damage assembly, comprising a central rod, a damping rod, and a curved plate;

[0010] The center rod is inserted into the first mounting groove and the second mounting groove, the damping rod is fixed on the outside of the center rod and is evenly distributed, and there are three arc plates fixed on the other end of the damping rod and symmetrically distributed on the outside of the center rod in a ring shape.

[0011] Furthermore, the anti-damage assembly further includes a first through hole and a first support frame, a second through hole and a second support frame;

[0012] The first through hole is opened in the middle of the center rod, and the first support frame is inserted into the first through hole. The second through hole is opened in the middle of the arc plate, and the second support frame is inserted into the second through hole.

[0013] Furthermore, the three arc-shaped plates are not fitted together but are movably connected.

[0014] Furthermore, the first installation groove and the second installation groove match each other, and the outer side of the arc-shaped plate fits against the inner side of the first installation groove and the second installation groove.

[0015] Furthermore, the coupling further comprises a mounting hole and a transmission shaft;

[0016] The mounting holes are formed on the steel sleeve and are evenly distributed, and the transmission shaft is plugged into the center of the shaft.

[0017] Furthermore, it also includes an anti-wear component;

[0018] The anti-wear component includes a limit plate and a sponge;

[0019] The limiting discs are injection-molded and connected to both ends of the central rod. There are three sponges in total, which are inserted between the arc-shaped plate and the central rod.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. The utility model connects the arc plate to the center rod through the damping rod through the anti-damage component, and uniformly inserts it into the first mounting groove and the second mounting groove, and fixes the end face of the coupling on the crushing body. When the equipment is running, the motor drives the coupling to rotate, and then drives the anti-damage component to shake, causing the arc plate to shake and the damping rod to expand and contract. When the temperature changes, the first through hole and the second through hole can release stress, and the first support frame and the second support frame can reduce the degree of deformation. This setting can reduce the impact of temperature changes on the connection between the steel sleeve and the shaft, as well as the gap in the connection caused by vibration, thereby reducing damage to parts in the coupling and increasing service life.

[0022] 2. The utility model sets up an anti-wear component, and a sponge soaked in lubricating oil is placed between the arc plate and the center rod. When the coupling rotates, the arc plate is driven to shake, squeezing the sponge, causing the lubricating oil to drip. This setting can increase the lubrication of the anti-wear component and the coupling, reduce wear, and increase service life. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0034] See also Figure 1-4 As shown, this embodiment is a coupling installation structure for a high-calcium stone three-eight block crusher, comprising:

[0035] The coupling includes a steel sleeve 10, a first mounting groove 11, a shaft 13 and a second mounting groove 14;

[0036] The first mounting groove 11 is provided on the inner side of the steel sleeve 10, and the second mounting groove 14 is provided on the outer side of the shaft 13. The shaft 13 is inserted into the steel sleeve 10.

[0037] The steel sleeve 10 surrounds the shaft 13 and provides additional protection and strength to ensure the structural stability of the entire coupling. The shaft 13 is the central part of the coupling and is usually used to connect two rotating parts to ensure that they can rotate synchronously. The first mounting groove 11 and the second mounting groove 14 act as limiters.

[0038] The anti-damage component includes a central rod 20, a damping rod 23 and a curved plate 24;

[0039] The center rod 20 is inserted into the first mounting groove 11 and the second mounting groove 14. The damping rods 23 are fixed to the outside of the center rod 20 and are evenly distributed. There are three arc-shaped plates 24, which are fixed to the other end of the damping rod 23 and are symmetrically distributed on the outside of the center rod 20 in a ring shape.

[0040] The center rod 20 plays a supporting role, the damping rod 23 plays a vibration reduction role, and the arc plate 24 plays a supporting and adjusting role;

[0041] The anti-damage assembly further includes a first through hole 21 and a first support frame 22, a second through hole 25 and a second support frame 26;

[0042] A first through hole 21 is formed in the middle of the center rod 20 , and a first support frame 22 is inserted into the first through hole 21 . A second through hole 25 is formed in the middle of the arc-shaped plate 24 , and a second support frame 26 is inserted into the second through hole 25 .

[0043] The first through hole 21 and the second through hole 25 are shrinkage holes that can absorb stress released due to temperature changes. The first support frame 22 and the second support frame 26 play a supporting role.

[0044] The three curved plates 24 are not fitted together and are movably connected;

[0045] The first mounting groove 11 and the second mounting groove 14 match each other, and the outer side of the arc-shaped plate 24 fits into the inner side of the first mounting groove 11 and the second mounting groove 14;

[0046] The coupling also includes a mounting hole 12 and a transmission shaft 15;

[0047] The mounting holes 12 are opened on the steel sleeve 10 and are evenly distributed. The transmission shaft 15 is inserted into the center of the shaft 13.

[0048] The mounting hole 12 is used for mounting bolts, and the transmission shaft 15 is used for connecting to the output end of the motor.

[0049] Working principle:

[0050] The arc plate 24 is connected to the center rod 20 through the damping rod 23, and is uniformly inserted into the first mounting groove 11 and the second mounting groove 14. The end face of the coupling is fixed to the crushing body. When the equipment is running, the motor drives the coupling to rotate, and then drives the anti-damage component to shake, causing the arc plate 24 to shake and the damping rod 23 to expand and contract. When the temperature changes, the first through hole 21 and the second through hole 25 can release stress, and the first support frame 22 and the second support frame 26 can reduce the degree of deformation.

[0051] This step can reduce the impact of temperature changes on the connection between the steel sleeve 10 and the shaft 13, as well as the gaps in the connection caused by vibration, thereby reducing damage to components in the coupling and increasing its service life.

[0052] See also Figure 3-5 This embodiment is based on the above embodiment and further includes:

[0053] The anti-wear component includes a limit plate 30 and a sponge 31;

[0054] The limit plates 30 are injection-molded and connected to both ends of the center rod 20. There are three sponges 31, which are inserted between the curved plate 24 and the center rod 20.

[0055] The limiting plate 30 plays a limiting role, and the sponge 31 is used to absorb lubricating oil and also plays a certain supporting role.

[0056] Working principle:

[0057] Soak the sponge 31 with lubricating oil and place it between the arc plate 24 and the center rod 20. When the coupling rotates, the arc plate 24 is driven to shake, squeezing the sponge 31 and causing the lubricating oil to drip.

[0058] This step can increase the lubrication of the anti-damage components and couplings, reduce wear and increase service life.
