Design of non-standard Customized Bronze bushings

When the demand for multi-custom bearings is put forward, there is a lack of careful analysis, resulting in problems such as poor bearing performance, many failures, and short service life. To avoid similar situations, refer to the following four-step requirement process:

1. Identify performance requirements

Two basic performance requirements determine the role that bearings play in practical applications. Therefore, the proposal of bearing requirements must include: providing rotational degrees of freedom within the specified range. Provides position control within a specified range (from basic free motion to high-frequency motion or vibration). Determining the actual limits of these requirements is important because bearing life is a statistical prediction within these limits.

2. Determine application parameters

Many application parameters determine product performance. Although only a few parameters may be important in a particular application, careful analysis of all parameters is necessary to ensure that no important parameters are missed.
Performance application parameters can be divided into the following 4 categories:
1. Physical parameters. Including the available space of the bearing or bearing system, The bearing or bearing system can bear the load, the shape, material, dimension, and tolerance control of the shaft and housing is integrated into the bearing to simplify the installation structure
2. The higher the working temperature, the greater the available space and the bearing load of the bearing system, and the higher the precision and reliability. However, the cost of adding additional bearing loads is high, so there is no need to add them unless necessary. The design of the shaft and housing has a large impact on the final bearing performance. The shaft should be a solid cylinder and the material used should be fully compatible with the thermal expansion coefficient of the bearing. The cross-section of the housing should be uniform to provide full circumferential support for the bearing. To ensure precise alignment, the shaft and housing should also feature precision machined shoulders or races.
3. Operating parameters. include:
3.1 Speed determines the number of load cycles that the bearing can withstand, and thus affects the service life of the bearing. Speed is usually expressed in terms of the relevant guide parameter “dN”, which also affects other aspects of bearing operation, including oil flow profile, oil film thickness, centrifugal load on rolling elements, displacement, overheating, and lubrication method.
3.2 Load can be decomposed into three directions radial, axial, and bending moment and the loads in these three directions will correspondingly generate constant load, alternating load, vibration load, or shock load. The combined effects of these loads should be carefully considered to ensure maximum bearing life and optimum performance.
3.3. Environmental parameters, the environment is a fixed factor for the final product, but whether the bearing is to be protected or exposed to a certain environment is an optional design factor. Either ambient temperature or internally generated temperature should be considered as the main consideration. The nature of the surrounding medium (liquid or gas) may place certain requirements on tightness, special anti-corrosion treatments, or relubrication. In addition, any special environment (such as a magnetic field or radiation environment) is also a necessary factor that should be considered in the design.
3.4. In Economic parameters, the total system cost should be carefully weighed, not only the bearing cost but also the total cost of bearing installation and replacement should be considered.
Many parameters are fixed in a specific application, but some are variable and can be modified or controlled if necessary. The designer makes the final choice after weighing these parameters.

3. Assess Potential Damage Modes

If the performance is so significantly reduced that the bearing no longer meets the original requirements, the design life of the bearing in a particular application will be reduced. There are 15 common injury modes:
foreign object wear
Etching Assistant
Insufficient lubrication
Fatigue peeling
Transitional preload or overload
The shaft end clearance is too large
Inaccurate and misaligned seat washer and shoulder
Damage during transportation and installation
Damage to bearing cage or fixings
Raised locations and damage during assembly
Improper mounting of housing or shaft
Brinell indentation damage and impact damage
False Brinell indentation
electrical burn
to calculate the service life. Other factors are empirical factors related to a particular application, such as temperature, lubrication, overloa,ding or contamination, which may reduce service life.

4. Determine bearing design

The above factors must be carefully considered before selecting a specific bearing. For more demanding application fields, specific design schemes or control methods can be formulated according to the following contents:
Lubrication type, method, cycle
Use of dust caps or seals
Cage configuration, material, and clearance
Basic tolerances and corrections
Radial clearance or contact angle
preload
material change
Geometry Correction for Contact Areas
Special balls or ball accessories

Casting Method Of Copper Bushing

1. Sand casting bronze parts

Sand casting is the most common method used in production.

It has the advantages of wide adaptability and relatively simple production preparation. However, the dimensional accuracy, surface quality, and internal quality of castings produced by this method are far from meeting the requirements of mechanical parts, and the production process is more complicated, and the realization of mechanized and automated production requires huge investment. In the production of some special parts and special technical requirements When casting, the technical and economic indicators are low, therefore, the application of sand casting in foundry production
subject to certain restrictions.

2. Special casting bronze bushings

Various other casting methods different from sand casting have been formed by changing the casting material, pouring method, the form of liquid alloy filling the casting mold, or the solidification conditions of the casting.

Extrusion and liquid stamping casting. It is a comprehensive processing method of casting and forging.
Metal mold casting. It is a method of using a metal mold to increase the cooling rate of the casting, achieve one-type multi-casting, and obtain a casting with a dense crystalline structure.
Continuous casting. It is an efficient production method for casting tubes and ingots under the conditions of continuous casting, solidification and cooling through a rapid cooling mold.
Centrifugal cast copper sleeve. It is a method of casting special castings such as rings, tubes, cylinders, and sleeves by changing the filling mold and solidification conditions of liquid alloys and using centrifugal force.
Investment casting. It is a method of casting no-cut or less-cut castings with higher dimensional accuracy and lower surface roughness values using fusible models and high-performance shells (molds).
Die casting. It is a method of obtaining precision castings by changing the filling and crystallization and solidification conditions of the liquid alloy, so that the liquid alloy fills the mold under high pressure and high speed, and is formed and crystallized under high pressure.
Lost foam casting. It is to bond and combines foamed plastic models similar in size and shape to castings into a model family. After brushing a refractory coating and drying, it is buried in quartz sand for vibration modeling, and then liquid metal is poured under certain conditions to vaporize the model. The method of making the molten metal occupy the position of the model, and forming the required casting after the molten metal solidifies and cools.
