[0002] The bearing seat is a large and extra-large bearing seat that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, flexible rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is often called the bearing seat. Since a bearing can use different bearing seats, and a bearing seat can also use different types of bearings, there are many varieties of bearing seats. However, the markings of the same bearing seat model in different company samples are not exactly the same. For different applications of standard bearing seats, you can choose bearing seats made of different materials such as: gray cast iron, ductile iron and cast steel, stainless steel, and plastic special bearing seats.

[0003] However, with the development of the times, the application of bearing seats is becoming more and more extensive, and the forms and working methods are also very different. However, for bearing seats in some special environments, it is more special. For example, in the prior art, for some two shafts working at the same time at a close distance, two bearing seats need to be installed at the same time, which greatly increases the cost. The rotating shaft-connected bearing seat in the prior art is just an improvement on the original single-body bearing seat to work with two single-body bearing holes, and the traditional bearing seat has poor flexibility and cannot be moved.

[0004] In view of this, the present utility model is proposed. Utility Model Content

In the present arrangement, the slide groove 13 on the second base 2, the first fixed threaded hole 3 and the second fixed threaded hole 15 on the third base 4 allow the distance between the two bearing seats to be changed as required, thereby avoiding the method of customizing a large number of machines one by one during use, thereby greatly reducing its cost expenditure.

[0025] like Figures 1 to 5 As shown, in a specific embodiment, a semicircular copper ring 8 is connected to the inner side of the lower bearing frame 5 and the upper bearing frame 11. In this configuration, the semicircular copper ring 8 greatly reduces its wear and tear, and can be fixed by the bracket bolt 7 and the bracket threaded hole.

[0026] like Figures 1 to 5As shown, further, a lubricating oil hole 10 is opened on one side of the axis of the upper bearing frame 11, and the number of the lubricating oil holes 10 is two. In this configuration, the lubricating oil holes 10 make it convenient to add lubricating oil to the bearing seat. The lubricating oil hole 10 of the left bearing seat can be poured into the lubricating oil hole 10, and the excess lubricating oil overflows from the lubricating oil hole 10 on the right side.

[0027] like Figures 1 to 5 As shown, further, four first fixing bolts 12 are provided on the surface of the first base 1. In this configuration, the first fixing bolts 12 fix the first base 1 on the machine, making the bearing seat detachable and increasing the portability of the bearing seat.

[0028] like Figures 1 to 5 As shown, further, the slide groove 13 is rectangular, and lubricating oil is applied to the inside of the slide groove 13.
