Description
Technical Field
The utility model relates to a composite main shaft sleeve of a single-cylinder hydraulic cone crusher, which has high wear resistance, low cost and long service life and belongs to the field of cone crusher manufacturing.
Background
At present, single-cylinder hydraulic cone crushers sold in the market are mature products, and bearing steel is adopted in a shaft sleeve on the upper portion of a main shaft of the single-cylinder hydraulic cone crusher in structural design. The method has the following defects: firstly, because the bearing steel shaft sleeve and the top bearing of the main shaft of the single-cylinder hydraulic cone crusher are made of the same material, when the main shaft rotates to crush stones, the bearing steel shaft sleeve sleeved on the upper part of the main shaft forms relative friction between acting force and reacting force, so that the wear rate of the bearing steel shaft sleeve and the top bearing is very large, and the service life of the bearing steel shaft sleeve and the top bearing is often less than 6 months; secondly, because of the high manufacturing difficulty and high cost of the bearing steel shaft sleeve, the weight of one bearing steel shaft sleeve is 132.2Kg, and the manufacturing cost is nearly 4000 yuan RMB.
Disclosure of Invention
The design purpose is as follows: the composite main shaft sleeve of the single-cylinder hydraulic cone crusher and the single-cylinder hydraulic cone crusher are designed to avoid the defects in the background technology, and have the advantages of high wear resistance, low cost and long service life.
The design scheme is as follows: in order to achieve the above design objectives. On the basis of the background technology, the utility model adopts carbon steel as the main shaft sleeve on the upper part of the main shaft of the single-cylinder hydraulic cone crusher, and adopts a design that a high manganese steel welding rod is adopted to build up a high manganese steel layer on the upper part of the shaft sleeve (the part matched with a top bearing) to form a composite main shaft sleeve. The purpose of this design is: the high manganese steel can reach HB 300-400 under low impact load and HB 500-800 under high impact load. With different impact loads, the depth of the surface hardening layer can reach 10-20 mm, and the high-hardness hardening layer can effectively resist the abrasion of impact abrasive materials. According to the utility model, by utilizing the characteristic of high manganese steel, a high manganese steel layer is overlaid on the matching part of the main shaft sleeve and the top bearing of the single-cylinder hydraulic cone crusher by adopting a high manganese steel welding rod, and is matched with the top bearing after processing, because the hardness of the top bearing is about HB210, and the surface hardness of the high manganese steel reaches HB 500-800, when the high manganese steel layer in the top bearing and the composite main shaft sleeve generates impact friction, the surface hardening layer of the high manganese steel layer is further deepened along with the increase of the impact friction force, so that the composite main shaft sleeve is not abraded, but has excellent wear resistance, and the service life is greatly prolonged.
The technical scheme is as follows: a high-manganese steel layer is built up on the matching part of a carbon steel main shaft sleeve and a top bearing, and the high-manganese steel layer is processed to form the high-wear-resistance single-cylinder hydraulic cone crusher composite main shaft sleeve consisting of the carbon steel main shaft sleeve and the high-manganese steel layer.
Compared with the background technology, the composite spindle sleeve has the advantages of high wear resistance, low cost and long service life, and brings unexpected technical effects and economic benefits as follows:

Detailed Description
Example 1: reference is made to figures 1 and 2. A high-wear-resistance composite main shaft sleeve 1 of a single-cylinder hydraulic cone crusher is formed by processing a high-manganese steel layer 2 formed by surfacing a carbon steel main shaft sleeve and a top bearing matching part and forming a high-wear-resistance composite main shaft sleeve 1 of the single-cylinder hydraulic cone crusher, wherein the high-manganese steel layer 2 is formed by the carbon steel main shaft sleeve (a carbon steel layer 3) and the high-manganese steel layer 2. The thickness of the high manganese steel layer is 1.4-1.6 mm, and preferably 1.5 mm. The thickness of the carbon steel layer is 1.4-1.6 mm, and preferably 1.5 mm.
It is to be understood that: although the above embodiments have described the design idea of the present invention in more detail, these descriptions are only simple descriptions of the design idea of the present invention, and are not limitations of the design idea of the present invention, and any combination, addition, or modification without departing from the design idea of the present invention falls within the scope of the present invention.
