Description

Technical Field

[0001] The present invention relates to the technical field of mining machinery, in particular to a counterweight ring for a crusher. Background Art

[0002] As the core equipment in mining, the crusher's spindle system has been subjected to high-intensity impact loads for a long time. With the development of larger equipment, the spindle speed has increased to the range of 800-1200rpm. The traditional symmetrical counterweight structure is difficult to meet the dynamic balance requirements. The existing technology mostly uses steel blocks of different masses welded at specific positions on the spindle to achieve balancing, but welding thermal deformation will cause new imbalance.

[0003] In view of the above-mentioned related technologies, it is urgent to design and develop a counterweight ring for crushers to optimize the dynamic balance performance of the main shaft system, effectively reduce vibration and noise, improve the operating stability and service life of the equipment, and ensure that excellent balance effects can be maintained at high speeds. Summary of the Invention

[0030] The counterweight ring 1 is placed in the crusher. The counterweight ring 1 is a ring structure. The clamping mechanism 3 includes a placement ring 31, a support ring 32, a clamping ring 33, a positioning block 34, a connecting ring 35 and a clamping ring 36. The placement ring 31 is arranged on the counterweight ring 1. The placement ring 31 is coaxial with the counterweight ring 1, and the lead-filled cavity ring block 2 is arranged on the placement ring 31.

[0031] Reference Figure 1 and Figure 3 As shown, the lead-filled cavity ring block 2 is a semi-ring structure. The lead-filled cavity ring block 2 is coaxially arranged with the counterweight ring 1. A counterweight lead block 21 can be arranged in the lead-filled cavity ring block 2. An annular groove is provided on the side of the lead-filled cavity ring block 2 close to the counterweight ring 1. Mounting ears 23 are provided in the lead-filled cavity ring block 2. There are four mounting ears 23, and the four mounting ears 23 are evenly distributed at equal distances along the inner wall of the lead-filled cavity ring block 2.

[0032] Reference Figure 1 and Figure 3 As shown, a clamping plate 24 is provided in the lead-filled cavity ring block 2. There are four clamping plates 24, which are evenly distributed at equal distances along the inner wall of the lead-filled cavity ring block 2. The clamping plates 24 correspond to the mounting ears 23 one by one. One side of the clamping plate 24 is connected to the mounting ear 23, and the other side of the mounting ear 23 passes through the annular groove and is connected to the outer side surface of the counterweight ring 1, so as to facilitate the fixed connection of the lead-filled cavity ring block 2 with other components.

[0033] Reference Figure 1 and Figure 3As shown, the counterweight lead block 21 is annular, and an ear groove 211 is provided on the outer circumference of the counterweight lead block 21 for cooperating with the mounting ear 23. The mounting ear 23 is inserted into the ear groove 211. A plug-in groove 212 is provided on the counterweight lead block 21, and a clamping plate 24 is inserted into the plug-in groove 212. When the lead-filled cavity ring block 2 is filled with lead to form the counterweight lead block 21, the mounting ear 23 and the clamping plate 24 are used to improve the stability of the connection between the counterweight lead block 21 and the lead-filled cavity ring block 2.

[0034] Reference Figure 1 and Figure 3 As shown, the counterweight ring 1 is designed to be asymmetrical, so that the center of gravity of the entire counterweight ring 1 is no longer located on its rotation axis, but is eccentric. When the counterweight ring 1 with eccentric mass rotates with the eccentric sleeve, it will generate a centrifugal force vector with a constant magnitude but a direction that continuously changes in the rotation plane (changes synchronously with the rotation). By accurately calculating the weight and position of the counterweight block, the magnitude and phase (angle) of the rotating centrifugal force vector generated by this "unbalanced" counterweight can be adjusted to exactly offset (or mostly offset) the centrifugal inertia force vector generated by the moving cone at the same speed and with continuously changing direction, so that the equipment can still maintain the required dynamic balance performance when running at high speed, thereby improving the operating stability and service life of the equipment.

The axial centerline direction of the oil groove ring 11 coincides with the axial centerline direction of the counterweight ring 1. The outer side surface of the oil groove ring 11 fits with the inner side wall of the lead-filled cavity ring block 2. An oil outlet hole 12 is opened in the oil groove ring 11. The oil in the oil groove ring 11 can flow downward along the oil outlet hole 12 to facilitate lubrication of the lower components.

[0037] Reference Figure 1 and Figure 2As shown, the positioning block 34 is arranged on the oil groove ring 11, and the positioning block 34 is located above the support ring 32. A positioning hole 341 is opened on the top surface of the positioning block 34. The connecting ring 35 is arranged in the oil groove ring 11, and the connecting ring 35 is arranged coaxially with the counterweight ring 1.

[0038] Reference Figure 1 and Figure 2 As shown, the outer side surface of the clamping ring 36 fits into the inner side wall of the connecting ring 35. When the counterweight ring 1 needs to be fixed under other components, the positioning block 34 is connected to the other components through screws 55, and the clamping ring 36 can be clamped to the other components, making it easier to install the counterweight ring 1 under other components.

[0039] Reference Figure 1 As shown, the mounting mechanism 4 includes a mounting ring 41 and a positioning ring 42. The mounting ring 41 is arranged on the counterweight ring 1. The mounting ring 41 and the counterweight ring 1 are coaxially arranged. The mounting ring 41 is located below the clamping ring 36. A mounting hole 411 is provided on the top surface of the mounting ring 41. A through groove 412 is provided on the edge of the mounting ring 41.

The limiting arc block is slidably set in the limiting arc groove 512. The sliding arc seat 53 is slidably set on the placement ring block 51. The sliding arc seat 53 is connected to the sliding arc block 52, and the screw 55 is threadedly sleeved on the sliding arc seat 53. The abutment plate 54 is set on the screw 55.

[0043] Reference Figure 1 and Figure 2 As shown, when the counterweight ring 1 needs to be fixed to other components of different sizes, the screw 55 is rotated so that the abutment plate 54 abuts against other components, which facilitates the fixing of the counterweight ring 1 to other components of different sizes. The limiting arc block prevents the sliding arc block 52 from detaching from the placement ring, thereby improving the stability of the sliding connection between the sliding arc seat 53 and the placement ring.

[0044] The implementation principle of a counterweight ring 1 for a crusher in the embodiment of the present application is as follows: The counterweight ring 1 is placed in the crusher. The counterweight ring 1 has a ring structure and is equipped with a lead-filled cavity ring block 2. The lead-filled cavity ring block 2 is a semi-ring structure. The counterweight ring 1 and the lead cavity ring block are arranged coaxially. A counterweight lead block 21 can be set in the lead-filled cavity ring block 2. The counterweight ring 1 is designed to be asymmetrical, so that the center of gravity of the entire counterweight ring 1 is no longer located on its rotation axis, but is eccentric. When the counterweight ring 1 with this eccentric mass rotates with the eccentric shaft sleeve, it will generate a centrifugal force vector with a constant magnitude but a direction that continuously changes within the rotating plane (changing synchronously with the rotation). By accurately calculating the weight and position of the counterweight block, the magnitude and phase (angle) of the rotating centrifugal force vector generated by this "unbalanced" counterweight can be adjusted to exactly offset (or mostly offset) the centrifugal inertia force vector with a continuously changing direction generated by the moving cone at the same speed. This ensures that the equipment can still maintain the required dynamic balance performance during high-speed operation, thereby improving the equipment's operating stability and service life.
