Description

Technical Field

[0001] The utility model relates to the field of chemical pumps, in particular to a shaft bearing of a chemical pump. Background Technique

[0002] The chemical pump is an energy-saving pump designed jointly across the country. The performance of the pump has a reasonable layout of the overall series of hydraulic performance, a wide range of user choices, a "rear-opening" structure, convenient maintenance, and its efficiency and suction lift reach the international advanced level.

[0003] The shaft bearing of the chemical pump is used for the connecting component of the driving part of the pump and the motor. Currently, the shaft end of the pump body is directly connected to the motor, resulting in easy fracture of the connected shaft.

[0004] However, for a traditional shaft bearing of a chemical pump on the market currently, its structure is not optimized enough and the design is not reasonable enough. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shaft bearing of a chemical pump to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A shaft bearing of a chemical pump includes a base. A lower cover is fixedly connected to the top of the base. An upper cover is installed on the top of the lower cover. A second side block is fixedly connected to the outer wall of the lower cover. A first side block is fixedly connected to the outer wall of the upper cover. A locking pin is installed on the top of the first side block. The bottom of the locking pin is threadedly connected to the first side block and the second side block. A bearing is arranged between the upper cover and the lower cover. An inner shaft ring is installed at the inner ring part of the bearing.

[0008] As a further scheme of the utility model: Front half rings are installed on the front surfaces of the upper cover and the lower cover. A shaft rod is installed between the two front half rings.

[0009] As a further scheme of the utility model: Axial beads are installed between the bearing and the inner shaft ring.

[0010] As a further scheme of the utility model: A shaft rod is arranged at the axial center part of the inner shaft ring. The shaft rod is fixedly connected to the inner cavity of the inner shaft ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In this utility model, the lower cover fixed to the top of the base is used to dock with the upper cover. The side block two fixed to the outer wall of the lower cover and the side block one on the outer wall of the upper cover are used in conjunction with a locking pin. The side block one and the side block two are fixed through the threaded connection of the locking pin, so that the upper cover and the lower cover are integrated into a whole. The bearing assembled between the upper cover and the lower cover is docked with the inner race through the shaft beads, and then the inner race is docked with the shaft rod. Thus, after the shaft rod rotates, it can drive the inner race to rotate stably in the inner cavity of the bearing, and its structure is more optimized and the design is more reasonable.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a chemical pump bearing bush includes a base 1. A lower cover 2 is fixedly connected to the top of the base 1. An upper cover 4 is installed on the top of the lower cover 2. A side block two 10 is fixedly connected to the outer wall of the lower cover 2. A side block one 5 is fixedly connected to the outer wall of the upper cover 4. A locking pin 6 is installed on the top of the side block one 5. The bottom of the locking pin 6 is threadedly connected to the side block one 5 and the side block two 10. A bearing 7 is provided between the upper cover 4 and the lower cover 2. An inner race 8 is installed in the inner ring part of the bearing 7. Front half rings 9 are installed on the front sides of the upper cover 4 and the lower cover 2. A shaft rod 3 is installed between the two front half rings 9. Shaft beads are installed between the bearing 7 and the inner race 8. A shaft rod 3 is provided at the center of the inner race 8, and the shaft rod 3 is fixedly connected to the inner cavity of the inner race 8.

[0019] The working principle of the present utility model is:

[0020] In use, the lower cover 2 fixed to the top of the base 1 is used to dock with the upper cover 4. The side block two 10 on the outer wall of the lower cover 2 and the side block one 5 on the outer wall of the upper cover 4 are adapted with a locking pin 6 for use. The side block one 5 and the side block two 10 are fixed by the threaded connection of the locking pin 6, so that the upper cover 4 and the lower cover 2 are integrated into a whole;

[0021] The bearing 7 assembled between the upper cover 4 and the lower cover 2 is docked with the inner race 8 through the ball bearings, and then the inner race 8 is docked with the shaft rod 3. Thus, after the shaft rod 3 rotates, the inner race 8 can be driven to rotate stably in the inner cavity of the bearing 7.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
