Description

Technical Field

[0001] The utility model belongs to the technical field of bearing production, in particular to a bearing seat installation structure. Background Art

[0002] In current production equipment or production devices, drive or power transmission is inseparable from the rotating shaft. Bearings are matched at both ends of the rotating shaft, and then each is installed on the corresponding equipment through a bearing seat.

[0003] To ensure smooth rotation of the shaft, there are certain requirements for the concentricity of the center lines of the bearing holes of all bearing seats supporting the shaft. Therefore, the position of the bearing seat needs to be repeatedly adjusted during installation, mainly in the vertical direction and left and right direction (the direction perpendicular to the center lines of the bearing holes of the bearing seat). The vertical position of the bearing seat is adjusted mainly by adjusting the thickness of the gasket between the equipment and the bottom of the bearing seat. However, the existing bearing seat installation structure lacks a temporary support structure for the bearing seat, and the metal gasket can only be rigidly stuffed under the bearing seat, which makes adjustment inconvenient, wastes time and manpower, and brings inconvenience to production.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figure 1 As shown, a bearing seat installation structure, the bearing seat 1 can adopt the existing bearing seat structure, the bearing seat 1 is installed on the top surface of the base 2 by bolts 6, the base 2 is installed on the corresponding equipment (omitted in the figure), and a gasket 3 is provided between the bottom surface of the bearing seat 1 and the top surface of the base 2. In this embodiment, the gasket 3 is a metal gasket, and a plurality of gaskets are provided. The gaskets are combined into a combination of different thicknesses to correspond to the space height between the bearing seat 1 and the base 2. The gaskets constituting the combination are sequentially inserted between the bearing seat 1 and the base 2 to support the bearing seat 1, and then the bearing seat 1 and the base 2 are connected and fixed by bolts.

[0023] In the present invention, the base 2 comprises an upper plate 21 and a lower plate 23 facing each other, and the upper plate 21 and the lower plate 23 are connected and fixed by two facing vertical plates 22. The gasket 3 is arranged between the upper plate 21 and the bottom surface of the bearing seat 1.

[0024] A lifting element 5 is threadedly installed in the center of the upper plate 21. The lifting element 5 is a handle screw, and its screw rod faces upwards and directly faces the bottom surface of the bearing seat 1. Two positioning pins 4 are vertically arranged on the upper plate 21. The two positioning pins 4 are arranged on both sides of the lifting element 5. The bottom surface of the bearing seat 1 is provided with positioning holes corresponding to the positioning pins 4. The top of the positioning pin 4 is inserted into the positioning hole to form a vertical movement limiting structure of the corresponding bearing seat 1. The handle screw temporarily supports the bearing seat 1. The handle screw is turned to lift the bearing seat 1. During the lifting operation of the lifting element 5 on the bearing seat 1, the vertical movement limiting structure ensures that the bearing seat 1 moves in the vertical direction, thereby realizing the adjustment of the position of the bearing seat 1 in the vertical direction.

[0025] In the present invention, mounting holes 24 are respectively provided at the left and right ends of the lower plate 23, and the mounting holes 24 are waist hole structures with the long sides perpendicular to the center line of the bearing seat 1. During assembly, screws are used to fix the base to the corresponding equipment through the mounting holes 24. Since the mounting holes 24 are waist hole structures, the position of the bearing seat 1 can be adjusted in the left and right directions.
