Description

A cone crusher shaft bracket Technical Field

[0001] This utility model relates to the field of cone crusher technology, specifically to a cone crusher shaft bracket. Background Technology

[0002] Cone crushers are a type of secondary crushing equipment widely used in industries such as mining, metallurgy, and building materials. They mainly achieve medium and fine crushing of materials through the principle of layered crushing. The core principle is that the electric motor drives the eccentric sleeve to rotate, which in turn drives the moving cone to make a gyratory motion, forming a periodic compression crushing with the fixed cone.

[0003] The cone crusher shaft bracket is located at the bottom of the transmission system and is used to fix the drive shaft and bearings to ensure the stability of power transmission. Existing cone crusher shaft brackets are cast in one piece, requiring complete replacement upon damage, resulting in unnecessary waste. Therefore, we propose a new cone crusher shaft bracket design. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a cone crusher shaft support, which solves the problems mentioned in the background art.

[0006] Technical solution

[0007] This utility model provides the following technical solution: a cone crusher shaft support, including a first shaft sleeve, a second shaft sleeve, a large flange, and an oil injection assembly;

[0008] The first bushing is provided with an oil injection component, which includes annular grooves equidistantly formed inside the first bushing. A connecting groove is formed through the annular grooves. An oil inlet groove is formed on one side of the connecting groove. A cotton strip is embedded inside the oil inlet groove. A wheel is provided at one end of the first bushing. A second bushing is provided at one end of the first bushing. A large flange is provided at the end of the second bushing close to the first bushing. An end plate is provided at the end of the second bushing away from the large flange.

[0009] Furthermore, a flange ring is fixedly provided on the outer side of the first bushing near the second bushing, and a sealing ring is provided on one side of the flange ring.

[0010] Furthermore, a mating groove corresponding to the first bushing is provided on one side of the large flange, and threaded holes are provided at equal intervals on one end of the large flange located outside the mating groove.

[0011] Furthermore, reinforcing ribs are provided at equal intervals on the outer side of the first bushing.

[0012] Furthermore, one end of the annular groove located on the outside of the first bushing is connected to a plug via a threaded groove.

[0013] Furthermore, reinforcing plates are provided at equal intervals on the outer side of the second bushing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Insert the end of the first bushing with the flange ring into the mating groove on one side of the large flange to complete the mating of the first bushing and the second bushing. Insert the bolt into the bolt hole in the flange ring and use a tool to screw the bolt into the threaded hole to fix the mated first bushing and the second bushing.

[0016] Remove the plug and inject the lubricating oil into the annular groove. The lubricating oil enters the annular groove and flows through multiple connecting grooves into multiple annular grooves. When the lubricating oil flows in the connecting grooves, it soaks the cotton strip and flows through the oil inlet groove into the first bushing, thereby flowing to the outside of the shaft or bearing to lubricate the shaft and bearing.

[0017] The shaft support of this cone crusher adopts a butt joint design, which forms a complete shaft support by connecting the first shaft sleeve and the second shaft sleeve. If the first shaft sleeve and the second shaft sleeve are damaged individually, they can be disassembled and replaced, and the drive shaft can be installed and disassembled easily.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4. In this embodiment of the utility model, it includes a first bushing 1, a second bushing 2, a large flange 3, and an oil injection assembly 6.

[0025] The first bushing 1 is provided with an oil injection component 6. The oil injection component 6 includes annular grooves 601 that are equidistantly opened inside the first bushing 1. A connecting groove 602 is opened through the annular grooves 601. An oil inlet groove 603 is opened on one side of the connecting groove 602. A cotton strip 604 is embedded in the oil inlet groove 603. A wheel 4 is provided at one end of the first bushing 1. A second bushing 2 is provided at one end of the first bushing 1. A large flange 3 is provided at the end of the second bushing 2 that is close to the first bushing 1. An end plate 5 is provided at the end of the second bushing 2 that is away from the large flange 3.

[0026] In this design, a flange ring 9 is fixedly installed on the outer side of the first bushing 1 near the second bushing 2, and a sealing ring 12 is provided on one side of the flange ring 9, which seals between the flange ring 9 and the large flange 3.

[0027] The large flange 3 has a mating groove 10 on one side corresponding to the first bushing 1, and threaded holes 11 are equidistantly provided at one end of the large flange 3 outside the mating groove 10. The opening of the mating groove 10 facilitates the insertion of one end of the first bushing 1.

[0028] Among them, the first bushing 1 is provided with reinforcing ribs 8 at equal intervals on the outer side, which can improve the strength of the first bushing 1.

[0029] Wherein, the end of the annular groove 601 located outside the first bushing 1 is connected to a plug 605 through a threaded groove, and the plug 605 is used to seal the oil filling port on the annular groove 601.

[0030] Among them, the second bushing 2 is provided with reinforcing plates 7 at equal intervals on the outer side. The reinforcing plates 7 can improve the strength of the second bushing 2 and at the same time improve the connection between the large flange 3 and the end plate 5.

[0031] The working principle of this utility model is as follows: Personnel insert one end of the first bushing 1, which has a flange ring 9, into the mating groove 10 on one side of the large flange 3 to complete the mating of the first bushing 1 and the second bushing 2. Bolts are inserted into the bolt holes in the flange ring 9 and screwed into the threaded holes 11 using a tool to fix the mated first bushing 1 and the second bushing 2. A sealing ring 12 seals between the first bushing 1 and the second bushing 2. One end of the first bushing 1 is equipped with a wheel 4, and one end of the second bushing 2 is equipped with an end plate 5, forming a complete transmission shaft frame. The transmission shaft is installed in the first bushing 1 and the second bushing 2 via a rotating bearing. The sleeve 2 is inserted into the cone crusher, and the shaft frame is fixed to the cone crusher using bolts through the large flange 3. The reinforcing rib 8 can improve the strength of the first shaft sleeve 1, and the reinforcing plate 7 can improve the strength of the second shaft sleeve 2, making it less prone to deformation and damage. Remove the plug 605 and inject lubricating oil into the annular groove 601. The lubricating oil entering the annular groove 601 flows through multiple connecting grooves 602 to multiple annular grooves 601. When the lubricating oil flows in the connecting grooves 602, it permeates the cotton strip 604 and flows through the oil inlet groove 603 to the first shaft sleeve 1, thereby flowing to the outside of the drive shaft or bearing to lubricate the drive shaft and bearing, so that it can rotate smoothly in the first shaft sleeve 1.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
