Abstract
The invention discloses a method for processing and assembling a stern shaft and a shaft sleeve, belonging to a processing and assembling method for ship machinery. The method is characterized by comprising the following steps of: (1) cleaning the processed stern shaft and coating lubricating oil on the surface of a corresponding fitting surface between the stern shaft and the shaft sleeve; (2) processing and shaping a copper shaft sleeve according to an original processing method, wherein the size processing ratio is 0.01-0.6 millimeter smaller than a preset size on a single side; (3) putting the copper shaft sleeve into a frying pan for heating to 40-70 DEG C, and preserving heat for 20-30 minutes; and (4) taking the copper shaft sleeve out and embedding into a corresponding position on the stern shaft. The most ordinary principle of expansion caused by heat and contraction caused by cold is utilized and introduced into assembly between the stern shaft and the shaft sleeve, so that the inner diameter of the shaft sleeve can be reduced, and the shaft sleeve can be smoothly and firmly arranged on the stern shaft. The assembling method is simple, and is easy and convenient to operate; and compared with an original method, the method disclosed by the invention has the advantage: the service life can be prolonged by 2-3 times.
Description
Technical field
The present invention relates to the method for processing and assembling of ship machinery, the method for a kind of specifically stern shaft and axle sleeve process and assemble.
Background technology
Axle sleeve in the existing marine rear shaft is to use copper product to make, and after axle sleeve is shaped according to the dimensioned of stern shaft, touches lubricating oil on the embedding face mutually of axle and axle sleeve on the quarter, then copper bush is embedded in the corresponding position of stern shaft.Yet use the gap that exists between stern shaft and the axle sleeve after existing assembly method is installed big, the rate of wear is fast, and along with the wearing and tearing of copper bush, and tailing axle concussion aggravation causes many problems such as ship running shakiness to occur.Also therefore, reuse after can only changing copper bush again.Because the material price of copper bush is high, often change, not only time-consuming, and many work and time that need bring to or the like.
Show to have only four related patent U.S. Patent No. (containing application) with stern shaft and axle sleeve at present from the interrelated data retrieval that comprises Chinese patent, but do not see the relevant report of stern shaft and axle sleeve assembly method as yet.
Summary of the invention
In order to overcome the defective of existing assembly method, the objective of the invention is to provide a kind of assembly method science to be suitable for, and the method for a kind of stern shaft that can increase the service life and axle sleeve process and assemble.
The technical solution adopted for the present invention to solve the technical problems is: the method for a kind of stern shaft and axle sleeve process and assemble is characterized in that:
1. the stern shaft after will machining cleans up, and touches lubricating oil on the surface of the corresponding mating surface of itself and axle sleeve;
2. copper bush is shaped by former processing method dimensioned, it is dimensioned to monolateral littler 0.01～0.6 millimeter than the former size of drafting;
3. copper bush is put into oil cauldron and be heated to 40～70 degree back constant temperature 20～30 minutes;
4. take out copper bush, be embedded on the relevant position of stern shaft.
The interior hole dimension of described copper bush is definite according to the size of stern shaft for monolateral little 0.01～0.6 millimeter than the former size of drafting, general stern shaft corresponding to diameter of phi 200～Φ 400.
The oil of described oil cauldron is to use existing 20～No. 40 regular engine oil.
Described assembling is in the workshop of normal temperature state, to carry out.
The invention has the beneficial effects as follows: because invention has utilized the general principle that expands with heat and contract with cold, it is referred among the assembling between stern shaft and the axle sleeve, so both can make the internal diameter of axle sleeve littler, can smoothly and be fixedly mounted on the stern shaft again than former internal diameter.Therefore, assembly method of the present invention is not only simple, and easy and simple to handle, and can improve 2～3 times of service lifes than what former method was assembled.
The specific embodiment
Embodiment 1:
It is the stern shaft of 260mm that a diameter is arranged, and wherein the processing dimension stern shaft is
sleeve diameter
1. the stern shaft after will machining cleans up, and touches lubricating oil on the surface of the corresponding mating surface of itself and axle sleeve;
2. copper bush is processed into by former processing method and dimensional requirement;
3. copper bush is put into oil cauldron and be heated to 60 degree back constant temperature 30 minutes;
4. take out copper bush, be embedded on the relevant position of stern shaft.
Claims (2)
1. the method for stern shaft and axle sleeve process and assemble is characterized in that:
1. the stern shaft after will machining cleans up, and touches lubricating oil on the surface of the corresponding mating surface of itself and axle sleeve;
2. copper bush is shaped by former processing method dimensioned, it is dimensioned to monolateral littler 0.01～0.6 millimeter than the former size of drafting;
3. copper bush is put into oil cauldron and be heated to 40～70 degree back constant temperature 20～30 minutes;
4. take out copper bush, be embedded on the relevant position of stern shaft.
2. the method for a kind of stern shaft according to claim 1 and axle sleeve process and assemble is characterized in that: the size of described copper bush endoporus is a stern shaft corresponding to diameter of phi 200～Φ 400 for monolateral little 0.01～0.6 millimeter.
