Abstract
Description
Technical Field
[0001] The utility model relates to a bearing seat, in particular to a bearing seat containing a ball bearing, belonging to the technical field of bearing seats. Background Art
[0002] Bearing seats are generally used in household air conditioners, commercial vehicle air conditioners, air film machines, air supply fans, etc.; non-ball bearings are installed in the bearing seats, which are essential and important components of these products and are the core components for shock absorption and noise reduction at the shaft end of such products. The bearing seat is a product molded by mixing synthetic rubber and then using a hydraulic vulcanizing machine with a composite mold for compression vulcanization. This product has excellent comprehensive properties such as oil resistance, physical and mechanical properties, and chemical resistance, and can be effectively utilized to meet various uses.
[0003] However, for some machines with fan blades used in special environments, such as dryers and dehumidifiers, due to the special use environment, if ordinary bearing seats are used, the non-ball bearings inside will cause abnormalities such as grease drying up due to continuous operation in a dry environment, resulting in short service life, as well as shaking and abnormal noise caused by heat wear during long-term operation. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a bearing seat containing a ball bearing to solve the defect of short service life in the above-mentioned existing technology, achieving the purpose of no shaking, no abnormal noise, and long service life.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a bearing seat containing a ball bearing, which is assembled and used with a fan fixing frame; it includes a bearing seat body and a ball bearing; the bearing seat body is a rubber body and adopts a metal-free design; the bearing seat includes an upper part, a middle part, and a lower part; a through hole A is provided at the center of the upper part; a through hole B is provided at the center of the middle part; a bearing installation hole is provided at the center of the lower part, and the ball bearing is installed in the bearing installation hole, and the inner diameter of the bearing installation hole matches the outer diameter of the ball bearing; a fan shaft passes through the center of the ball bearing; the outer periphery of the upper part is a disc-shaped periphery; the outer periphery of the middle part is a disc-shaped periphery, and the middle part is installed and used with the fan fixing frame; the outer periphery of the lower part is a large disc-shaped periphery, and the diameter of the lower part is greater than the diameter of the middle part, and the lower part is installed and used with the fan fixing frame; the through holes A and B form a fan shaft space; the diameter of the fan shaft space is greater than the diameter of the fan shaft; there are several fan-shaped grooves for shock absorption under the lower part.
[0006] A convex ring is provided between the upper part and the middle part.
[0007] There are several vertical convex strips A on the outer periphery of the upper part.
[0008] There are several vertical convex strips B on the outer periphery of the lower part.
[0009] The diameter of the orifice of the bearing mounting hole is smaller than the outer diameter of the ball bearing. During installation, an external force is used to squeeze the ball bearing into the orifice of the bearing mounting hole.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] 1. The requirements for the usage environmental conditions are low. For example, in an environment with a large amount of dust, high temperature, etc., the existing products cannot be used for a long time, and vibrations and abnormal friction noises will occur. However, this ball bearing seat can be used for a long time without fear of the above environmental conditions.
[0012] 2. The design principle adopted is that the products on the market use a steel shaft bearing to rotate inside, which will exacerbate wear and reduce the service life in some special environments. While this existing product uses the fan shaft end to be embedded in the inner hole of the ball bearing and fastened, and the fan is driven by the motor to rotate at the shaft end by the ball, thereby improving the abrasion resistance and service life of the product.
