Why are the bearings on the crankshaft of the engine sliding bearings? So high speed, sliding bearings friction is not great?? Fever will not be great? Please prawns in detail, thank you
Firstly, the sliding bearing is adopted, because the structure is simple, the cost is low, the lubrication is easy, the installation is convenient, the sealing is easy, the noise is low, and the precision is high.As long as the material clearance, not as you imagine so much wear and tear. In addition, for a precision problem, nor is it suitable for other bearings.
The utility model has the advantages of simple structure, low cost, easy lubrication, convenient installation, easy sealing, low noise and high precision.As long as the material clearance, not as you imagine so much wear and tear. In addition, for a precision problem, nor is it suitable for other bearings.
The reasons are as follows:The main reason is that the sliding bearing sleeve is two pieces, so it can be installed on the crankshaft. The rolling bearing can not be installed on the crankshaft.The utility model has the advantages of simple structure, low cost, easy lubrication, convenient installation, easy sealing, low noise and high precision. As long as the material pass, wear little.In addition, for a precision problem, nor is it suitable for other bearings.As for other places, both work speed, noise, work conditions, rotation accuracy, withstand shock, vibration ability, maintenance is not the same. The sliding bearing has the characteristics of high bearing capacity, good seismic resistance, low noise, long service life, etc. the rolling bearing has the characteristics of shock, vibration, noise and sealing. Rolling bearings are standard parts, easy to change. Plain bearings consume nonferrous metals.
