The advantages are that: firstly, the wear resistance is good, long service life has reduced manufacturing cost, brings unexpected technological effect.
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 defects in the background technology are avoided, and the composite main shaft sleeve of the single-cylinder hydraulic cone crusher and the equipment with high wear resistance, low cost and long service life are designed.
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 ZG60Si2Mn spring steel to manufacture the main shaft sleeve, and adopts the design that the upper part of the shaft sleeve (the part matched with a top bearing) is subjected to high-frequency quenching for penetration and the depth of a penetration layer is 2-3mm, which is the main technical characteristic of the utility model. The purpose of this design is: the hardness of the 60Si2Mn spring steel is about 34HRC before high-frequency infiltration, and after the high-frequency quenching infiltration treatment, the hardness of the spring steel is increased from about 34HRC to 55-60 HRC, and the spring steel has better toughness and is far greater than the hardness of a top bearing. Therefore, when the top bearing and the permeable layer main shaft sleeve generate impact friction, the top bearing cannot abrade the permeable layer main shaft sleeve, so that the service life of the permeable layer main shaft sleeve is greatly prolonged, the replacement of the main shaft sleeve is avoided, and meanwhile, the interference fit with the upper end part of the main shaft is conveniently realized because the inner wall of the main shaft sleeve is soft relative to the outer wall.
The technical scheme is as follows: the utility model provides a single cylinder hydraulic cone crusher oozes layer main shaft axle sleeve, the main shaft axle sleeve adopts ZG60Si2Mn spring steel preparation, the main shaft axle sleeve cooperatees with single cylinder hydraulic cone crusher's top bearing, and the main shaft axle sleeve side of cooperation department adopts high frequency hardening to permeate, the depth of permeable stratum is 2-3mm, the main shaft axle sleeve outward appearance permeable formation hardness that makes ZG60Si2Mn spring steel is greater than HRC55, be less than HRC65 and the relative outer wall of main shaft axle sleeve inner wall that ZG60Si2Mn spring steel made is soft.
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. The utility model provides a single cylinder hydraulic cone crusher oozes layer main shaft axle sleeve, the main shaft axle sleeve adopts ZG60Si2Mn spring steel preparation, main shaft axle sleeve 1 cooperatees with single cylinder hydraulic cone crusher's top bearing, and the main shaft axle sleeve side (portion) of cooperation department adopts high frequency hardening to permeate, the depth of permeable layer is 2-3mm (be 2-3mm within range optional value promptly and including the end value), the main shaft axle sleeve outward appearance hardness of making ZG60Si2Mn spring steel system is greater than HRC55, be less than HRC65 and the relative outer wall of main shaft sleeve inner wall that ZG60Si2Mn spring steel system made is soft.
Example 2: on the basis of the embodiment 1, the outer surface of the spindle sleeve is permeated by high-frequency quenching, the depth of the permeation layer 2 is 2-3mm, and the hardness of the outer surface of the spindle sleeve is greater than HRC55 and less than HRC 65. The hardness of the permeable layer on the outer surface of the spindle sleeve made of ZG60Si2Mn spring steel is greater than that of the top bearing of the single-cylinder hydraulic cone crusher.
Reference is made to figure 2. On the basis of embodiment 1 or 2, long-life single cylinder hydraulic cone crusher, including single cylinder hydraulic cone crusher, main shaft axle sleeve 1 and 3 interference fit of main shaft, permeable formation 2 matches with top bearing 4 in the main shaft axle sleeve 1. The hardness of the top bearing is smaller than that of the matching part of the spindle sleeve and the top bearing, and aims to solve the problems that: the main shaft sleeve 1 is ensured not to be abraded, when the top bearing 4 is damaged, only the top bearing needs to be replaced, and the top bearing 4 is very convenient to disassemble and assemble. The influence on production is very small, the replacement of the top shaft sleeve 1 is very difficult and careless, the main shaft is damaged, the replacement time is very long, the number of parts to be disassembled and assembled is very large, the parts are also very difficult, the production efficiency is directly influenced, and the method belongs to the field of overhaul.
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.
