The rubber bush, which is made up of a wide range of different rubbers, has two outer and inner parts, the outer part of which is a rubber cylinder, and in the inner part surfaces layer to rigid many kind of metal layer. Rubber bushes are commonly designed for torsional movement, axial or radial load, and deviation of the mix, and therefore bushes are used more often as engineering components.
These bushings are made in standard and well-defined sizes and are available in the market, but nevertheless, for specific purposes or unique needs, it is also possible to customize these rubber bushes.
What material is used to make rubber bushings?
Rubber bushes are used in a wide range of types of rubbers, and in fact both natural rubber and alternate elastomers, synthetic rubbers, are used in various grades to make rubber bushes.
How to install rubber bushings?
There are many ways to install these rubber bushes, depending on their type of use, but they are generally pressed rubber bushes into the space or in a particular space or are fitted at a time in assembly. In addition, in the assembly of parts of some devices, rubber bushes are used to compress the rubber against mating surfaces occasionally to prepare a preload.
types of rubber bushes?
In general, rubber bushes have a wide range and include a variety of types. In fact, rubber bushings are produced with different excitations and are also very important for the various NVH features.
But in general, rubber bushings can be summarized in the following types:
- Bush with a simple design
- Flange type bushings
- Multi-layer bushings or Laminated bushes
- bush with a vide design
- pivot bush types
- Spherical bush types
- Suspension bush types
- Equalizer bushings
- bushes with torque arm
- Conical bush types and so on
Manufacturing Process of Rubber Bushes
Generally, the following production process should be followed for preparation and sale Rubber bush in the market depending on the variety of consumption and goals required:
- The first step to produce a rubber bush is the choice of rubber and the preparation of the required compounds that must be purchased according to the specifications required for the desired product.
- Apart from the type of rubber, metal parts, cleaners, blasting, etc. should be provided to produce rubber bush.
- Next, the rubber Applying adhesive process should be done
- Using extrusion or compression technology, rubber molding compound with metal parts should be done.
- If needed, the bush should be Painted at this stage.
- The work of the rubber bush production is complete and must be put on the market.
- Using these bushes improve friction, wear and noise, and isolate high frequency vibrations.
General Features of rubber bushes
- Rubber bushes are usually produced for the displacement of torsional movements and axial and radial loads.
- In order to further increase the dynamic strength and durability of rubber bushes, they must be pre-stressed.
- The bonded rubber performs a complete movement
- Typically, rubber bushes do not require maintenance and lubrication or other bearing maintenance after production
- Most importantly, rubber bush indexes are highly flexible against noise and vibration
- The use of rubber bushes in different industries makes friction, abrasion and noise disappear and high frequency vibration does not occur.
Which Applications are used of rubber bushes?
Rubber bushes are used in many industries and every day they increase their range of use, but today, in general, rubber bushes are used in the following equipment:
- In the vehicle's suspension arms, rubber bushings are used
- For mechanical linkages on different devices
- In the case of vibrating feeders, rubber bushings are used
- In Pivot bearings today mostly used of rubber bushes.
- In the tracks of the conveyor used rubber bush and so on
