Abstract
The utility model discloses a water pump structure and a water pump, comprising a water pump body and a water pump shaft; and a bearing is arranged at the lower end part of the water pump shaft and is connected to the water pump body through a gasket and an elastic check ring. On the basis of not influencing the installation size and performance of the water pump, the abnormal abrasion of the elastic check ring is effectively avoided, and the potential safety hazard in the working process of the water pump is eliminated; simultaneously, the thrust ball bearing that increases for the holistic rotation of water pump is steady more reliable, effectively increases the life of water pump, reduces the water pump noise.
Description
Technical Field
The utility model relates to the technical field of motorcycle engine cooling systems, in particular to a water pump structure and a water pump.
Background
At present, the motorcycle with large discharge capacity is gradually becoming the mainstream, which makes the heart-water pump of the cooling system of the motorcycle engine more and more important. This also puts higher standards and requirements on the reliability and durability of the water pump.
When the existing water pump works, a water pump shaft rotates at a high speed, and the elastic retainer ring, the gasket and the small end face of the water pump body are in close contact without gaps under the action of the spring force in the mechanical seal; that is the circlip can not rotate along with the axle, and the retaining ring hole can abnormal wear when the rotation of axle, finally leads to the retaining ring to drop, arouses water pump shaft axial float, and the water pump card is dead.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical defects, the utility model aims to provide a novel water pump which effectively avoids the abnormal abrasion of an elastic retainer ring and eliminates the potential safety hazard in the working process of the water pump; simultaneously, the thrust ball bearing that increases for the holistic rotation of water pump is more steady reliable, effectively increases the life of water pump, reduces water pump structure and the water pump of water pump noise.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the technical scheme is that the water pump structure comprises a water pump body and a water pump shaft; and a bearing is arranged at the lower end part of the water pump shaft and is connected to the water pump body through a gasket and an elastic check ring.
Preferably, the bearing is a thrust ball bearing.
Preferably, a mechanical seal is arranged between the water pump body and the water pump shaft.
A water pump comprises the water pump structure.
The beneficial technical effects are as follows:
on the basis of not influencing the installation size and the performance of the water pump, the abnormal abrasion of the elastic check ring is effectively avoided, and the potential safety hazard in the working process of the water pump is eliminated; simultaneously, the thrust ball bearing that increases for the holistic rotation of water pump is steady more reliable, effectively increases the life of water pump, reduces the water pump noise.
Drawings
The utility model will now be described, by way of example, with reference to the accompanying drawings, in which:
figure 1 is a schematic diagram of the main structure of the present invention.
Shown in the figure:
water pump body 1
A water pump shaft 2;
a thrust ball bearing 3;
a gasket 4;
a circlip 5;
and (6) a mechanical seal.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Embodiment, as shown in fig. 1, a water pump structure and a water pump comprise a water pump body 1 and a water pump shaft 2; the lower end part of the water pump shaft 2 is provided with a bearing and is connected to the water pump body 1 through a gasket 4 and an elastic retainer ring 5.
The bearing is a thrust ball bearing 3.
And a mechanical seal 6 is arranged between the water pump body 1 and the water pump shaft 2.
On the premise of ensuring the installation size of the water pump, the height of the water pump body is shortened (the numerical value is the thickness of the thrust ball bearing), and the thrust ball bearing is added. When the water pump with the new structure works, the lower end faces of the elastic check ring 5, the gasket 4 and the thrust ball bearing 3 rotate along with the water pump shaft 2, the elastic check ring 5 can be an elastic check ring for a shaft, and the elastic check ring 5 and the water pump shaft 2 do not move relatively, so that the abnormal abrasion of the elastic check ring is effectively avoided on the basis of not influencing the installation size and the performance of the water pump, and the potential safety hazard in the working process of the water pump is eliminated; simultaneously, the thrust ball bearing 3 that increases for the holistic rotation of water pump is more steady reliable, effectively increases the life of water pump, reduces the water pump noise.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
