Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a water pump housing with a fixed thrust bearing. Background Technology

[0002] In traditional water pump structures, thrust bearings are usually independent parts, assembled on a fixed shaft. Due to the non-positioning structure design, the operating state is relatively unstable, and there is a risk of multi-faceted impact, which reduces the service life of the thrust bearing. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model proposes a water pump housing with a fixed thrust bearing. By assembling the thrust bearing inside the water pump housing, damage to the bearing due to impact is prevented.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: A water pump housing with a fixed thrust bearing includes a water pump housing and a thrust bearing. The thrust bearing is fitted into the interior of the water pump housing through a process groove provided on the water pump housing and the thrust bearing, and a fixing key formed by fixing adhesive injected into the process groove. The outer diameter surface of the thrust bearing in contact with the water pump housing is coated with fixing adhesive.

[0005] As a further improvement of this utility model, the process groove is composed of a pump casing groove disposed on the water pump casing and a bearing groove disposed on the thrust bearing, wherein the pump casing groove and the bearing groove are coaxial.

[0006] As a further improvement of this utility model, the bearing groove is a semi-circular groove.

[0007] As a further improvement of this utility model, the bottom of the bearing groove is provided with a chamfer.

[0008] As a further improvement of this utility model, the thrust bearing is a silicon nitride thrust bearing.

[0009] As a further improvement of this utility model, the fixing adhesive is epoxy AB adhesive.

[0010] As a further improvement of this utility model, the diameter of the process tank is 2mm.

[0011] The beneficial effects of this utility model are: This utility model provides a water pump housing with a fixed thrust bearing. By using a process groove formed by the pump housing groove and the bearing groove, and a fixing key formed by fixing glue injected into the process groove, the thrust bearing is transitionally fitted into the water pump housing. Compared with the prior art, this utility model is simple to operate, adds a limit, prevents the thrust bearing from being damaged by impact, and improves the service life of the thrust bearing.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figures 1 to 4 As shown, a water pump housing with a fixed thrust bearing includes a water pump housing 1 and a thrust bearing 2. The thrust bearing 2 is fitted with the water pump housing 1 in a transition fit. Specifically, the water pump housing 1 has two symmetrically distributed pump housing grooves 11 inside, and the thrust bearing 2 is made of silicon nitride, which has the characteristics of being not easy to break and wear-resistant.

[0016] Specifically, the thrust bearing 2 of this utility model has two bearing grooves 21 on the outer diameter surface of the two pump housing grooves 11. The lower half of the pump housing groove 11 is semi-circular, and the two bearing grooves 21 are both semi-circular grooves, which correspond to and cooperate with the lower half of the two pump housing grooves 11 to form two process grooves. The diameter of the two process grooves is 2mm.

[0017] During assembly, a fixing adhesive 3 is applied to the outer diameter surface of the thrust bearing 2 that contacts the water pump housing 1. The bearing groove 21 on the thrust bearing 2 corresponds to the pump housing groove 11 to form a process groove. The fixing adhesive 3 is injected into the process groove to form a fixing key, thereby fixing the thrust bearing 2.

[0018] Specifically, in this embodiment of the invention, the fixing adhesive 3 is epoxy AB adhesive. Furthermore, the bottom of the bearing groove 21 on the thrust bearing 2 is provided with a chamfered portion 22, which is used to form irregular keys during adhesive injection, thus enhancing fixation.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
