Description

Manufacturing system for bearing housing {Manufacturing system for bearing housing}

The present invention relates to a manufacturing system for a bearing housing, and more specifically, to a manufacturing system for a bearing housing that can be customized to specifications requested by a user.

In general, industrial machine tools and large mechanical equipment are equipped with a rotating shaft for power transmission and a bearing unit that supports the rotating shaft and distributes the axial load of the rotating shaft.

The bearing unit consists of a bearing that consists of an outer ring, an inner ring, and balls to support the rotating shaft, and a bearing housing in which the bearing is accommodated inside and fixed to the structure.

Meanwhile, the overall specifications of the bearing housing described above are determined based on the diameter of the rotating shaft and the diameter and height of the bearing to be coupled to the rotating shaft so that there is no tolerance between the bearing and the bearing housing.

Conventionally, for convenience of production and use, the diameter of the rotating shaft was divided into 5 mm units, and the specifications of the bearing were determined based on this. In addition, several models of bearing housings with preset dimensions for each bearing specification were manufactured and used.

However, in the past, as the bearing housing was manufactured in accordance with the specifications set by the manufacturer as described above, a rotating shaft with specifications not included in the manufacturer's specifications could not be used, and as a result, specifications not included in the manufacturer's specifications were used. When it was necessary to use a rotating shaft, there was a problem in that the bearing housing had to be modified or arbitrarily modified.

In addition, conventionally, due to the load applied on the rotating shaft and the increase in oil temperature caused by the rotation of the bearing, a tolerance is created between the bearing housing and the rotating shaft, as well as between the bearing housing and the bearing, which makes it difficult for the rotating shaft to be stably supported by the bearing. As a result, there was a problem with driving problems.
