Bearing seat role
The bearing seat is a component that is installed in the machine and closely matched with the bearing, which can ensure the normal operation of the bearing, reduce noise, extend the life of the bearing and many other functions. Specifically, the bearing seat mainly has the following functions:
1, the supporting role: the bearing seat plays the role of supporting the bearing, so that the bearing can carry the axial and radial load of the mechanical, and support the rotating shaft.
2, positioning function: the bearing seat can fix the bearing to an accurate position on the machine to ensure that the axial distance between the inner and outer rings of the bearing and the end cover is correct.
3, sealing effect: the bearing seat can be used to ensure that the internal lubricating oil of the bearing is clean and lubricated without leakage.
4, reduce noise: Because the flange part and groove part on the bearing seat reduce the transmission of vibration, thus reducing the noise of the machine.
Classification of bearing housings
According to its structure and characteristics, the bearing seat can be divided into the following types:
1, linear bearing seat: composed of plain bearings suitable for linear motion, often used in electrolytic machinery and automation equipment.
2, ring bearing seat: composed of a circular bearing and a transmission rod installed in the ring, often used in tensile machines and other occasions.
3, spherical bearing seat: composed of spherical sleeve, ring and pressure plate, can withstand radial and axial load, often used in heavy load, vibration equipment.
4, rolling bearing seat: by deep groove ball bearings, tapered roller bearings and cylindrical roller bearings, etc., the general overload capacity is strong.
Selection of bearing seat
The selection of bearing seat is based on the use of the machine requirements, including force characteristics, speed, vibration, ambient temperature and equipment life and other factors to choose. Mainly consider the following aspects:
1, load level: to choose the bearing capacity of the bearing seat to ensure the safe operation of the machine.
2, speed: different bearing seats have different speed ranges, so it is necessary to choose a bearing seat that can match the actual working speed.
3, working temperature: bearing seat in long-term work will be affected by high or low temperature, so choose the appropriate material to ensure reliability.
4, environmental conditions: to consider the working environment of the machine, such as wet, dusty and other conditions, you need to choose a bearing seat that can be waterproof and dustproof.
