Small and medium-sized external spherical bearing pedestal is generally cold installation.Traditionally, the outer spherical bearing seat was mounted with a hammer and a piece of old pipe.This can cause external forces to be transmitted through moving parts, damaging the raceway.The installation tool applies the external force to the outer spherical bearing seat ring with pressure matching, which helps to prevent the damage of the outer spherical bearing seat.

Before installation, usually oil bath heating outer spherical bearing seat at http://www.zcwz.com/shangcheng/c_peijian_352/.However, this method may contaminate the outer spherical bearing housing, resulting in premature failure of the outer spherical bearing housing.Today, induction heating is the most common means of heating the outer spherical bearing seat, which is due to its high control, efficiency and safety.Research and development scale of induction heater for outer spherical bearing housing.The induction heating of the outer spherical bearing seat has many functions, which is helpful to prevent the damage of the outer spherical bearing seat in the heating process.

It is a precursor to the use of hydraulic technology in the installation of outer spherical bearing seat. These technologies include the oil filling method and the drive mounting method.These methods can help simplify the configuration of the outer spherical bearing seat and help to install the outer spherical bearing seat accurately and simply.A wide variety of tools and equipment has also been developed to put these hydraulic technologies into practice.

According to the service position and the service condition and the environment condition to choose the specification size, the precision, matches the suitable outer spherical bearing seat is guarantees the outer spherical bearing seat service life and the feasibility premise.

1, use location: the outer spherical bearing seat is suitable to bear the radial load mainly radial and axial joint load, usually with two sets of outer spherical bearing seat paired use, mainly in the front and rear wheel hub of the automobile, active bevel gear, differential, reducer and other transmission parts.

2, allowed speed: in the environment of correct installation and good lubrication, it is allowed to be 0.3-0.5 times of the limit speed of the outer spherical bearing seat.Under normal circumstances, 0.2 times of the limit speed is the most appropriate.

3, allowed inclination Angle: generally, the outer spherical bearing seat is not allowed to tilt the shaft relative to the housing hole, if there is a tilt, the maximum is not more than 2 '.

4. Allowable temperature: under the condition of normal load, high temperature resistance and sufficient lubrication, the external spherical bearing seat is generally allowed to work at the ambient temperature of -30℃-150℃.
