Description

Assembled bearing

Technical Field

The present utility model relates to an assembled bearing.

Background

Bearings are important support parts in mechanical devices, and their manner of installation directly affects the operational performance and service life of the device. The existing assembly type bearing generally needs to install two bearings in an up-down combined mode, and the installation mode is widely adopted in various mechanical equipment.

The existing bearing assembly process is generally such that the lower end bearing is fixed on the equipment base first, then the upper end bearing is placed at a position right above the lower end bearing, then the upper and lower bearings are connected and fixed through a plurality of bolts, and finally an additional supporting member is required to be installed to ensure the stability of the upper end bearing. This mounting requires strict coaxiality and parallelism to ensure proper operation of the bearing.

However, existing modular bearings suffer from significant technical drawbacks. The most important problems are that the installation process is complicated and the structure is complex. Since the upper end bearing generally has a large mass, it is difficult to ensure long-term stable operation only by means of bolting. To solve this problem, additional supports have to be added to strengthen the fixation, which not only increases the number of parts, but also makes the installation process more complicated.

In the actual installation process, an operator needs to coordinate the fastening forces of a plurality of bolts at the same time so as to ensure the neutrality of the upper bearing and the lower bearing. This adjustment process is not only time consuming, but also prone to misalignment of the mounting accuracy due to improper operation. Particularly, in the occasion of frequent disassembly and assembly maintenance, the complex fixing mode obviously increases the maintenance workload.

Therefore, the development of the assembled bearing with simple structure and convenient installation has important practical significance. The design needs to simplify the installation process, reduce the number of parts and improve the installation efficiency and the use reliability while ensuring the stability of the upper end bearing.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected via an intervening medium, or in communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, an assembled bearing includes an upper bearing 1 and a lower bearing 2. The upper bearing 1 and the lower bearing 2 are respectively provided with mutually symmetrical fixing bolts 3. The fixing bolt 3 includes a nut 4 and a screw 5.
