High Hardness Crusher Machine Spare Parts High Wear Resistant Bearing Bush
The copper sleeve of cone crusher includes eccentric sleeve copper sleeve, moving cone copper sleeve and horizontal copper sleeve. The copper sleeve plays an important role in the operation of the machine, so let's understand.
Product description
The application of eccentric bush in cone crusher mainly shows in what aspects? We know that there are many wearing parts
in cone crusher, such as organic frame bush, eccentric bush, transmission bush, spherical bush, thrust bearing, etc., among
which the eccentric bush, as a wearing part in the core of cone crusher, plays a very important role and is very strict in selection
and matching. This paper briefly introduces Introduce the application of eccentric bush in cone crusher and how to select and match it?
Cone crusher is one of the main mining equipment. Because the broken object is very hard, the main working parts will be worn
in the operation. Eccentric bush is one of them. The eccentric bush is located in the eccentric bush part of the cone crusher.
The eccentric bush part is composed of the tapered Bush and the external eccentric bush. The product processing is
completed in the high-speed operation. The high temperature and pressure generated in the high-speed operation will cause
wear to the eccentric bush and the tapered bush. Therefore, the material selection of the eccentric bush needs to be
particularly strict.
Product features
The specific characteristics need to meet the following requirements One aspect:
1. The compressive strength and hardness of the material should be high, so as to ensure the wear resistance and compression resistance of the customized eccentric bushing;
2. In order to ensure the impact resistance of eccentric bushing, the elongation and toughness of the material should be large;
3. the friction coefficient of the material needs to be small and self-lubricating, so that the friction resistance produced by the eccentric bushing
during operation is small, so as to generate less heat, and the temperature will not be too high, resulting in the phenomenon of sleeve burning
4. The linear expansion coefficient of the material should also be small, so that the eccentric bushing will not cause the phenomenon of jacketing due to the decrease of lubrication clearance between the bushings caused by high temperature.
Replacement of eccentric copper sleeve
Put the eccentric sleeve upside down and take out the copper sleeve. Before the installation of the eccentric sleeve copper sleeve, check whether the inner hole of the eccentric sleeve has fracture traces, whether the surface is clean and whether the size is accurate. In case of special circumstances, handle it in time. Pay attention to that the temperature of eccentric sleeve and copper sleeve should be about 70 ℃ when pouring locking packing, and the oil hole must be aligned to ensure that there is no mistake.
