Description

New maintenance-free water guide bearing

technical field

The utility model relates to a novel maintenance-free water guiding bearing.

Background technique

At present, most water guide bearings use oil-lubricated structural metal bearings, generally using Babbitt alloy materials, and there are two lubrication methods: grease lubrication and thin oil. No matter what kind of oil lubrication, the structure of the bearing is relatively complicated. Maintenance brings certain troubles. If the metal bearing is poorly lubricated, it will cause burnt tiles. In addition, after a period of use, due to the wear and aging of the seals, the lubricating oil may leak and cause environmental pollution.

In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a new type of maintenance-free water guide bearing, so that it has more industrial utilization value.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a new type of maintenance-free water guide bearing using water lubrication. The bearing has a simple structure and has the function of automatically discharging sediment, which avoids cumbersome maintenance.

A new maintenance-free water guide bearing proposed by the utility model includes a bushing, a bearing bush and a bearing seat. The bushing is provided with a water tank along the axial direction. The cross section of the water tank is arc-shaped, rice-shaped, and bidirectional Spiral type or dovetail type, the material of the bushing is polymer nylon, the contact surface of the bearing pad and the bearing seat is a sphere, and the material of the contact surface of the bearing pad and the bearing seat is surfacing stainless steel.

Further, the water guide bearing is provided with a tile temperature monitoring hole that runs through the bushing, the bearing pad and the bearing seat, and a temperature sensor is arranged in the tile temperature monitoring hole.

Further, the water tank is connected with a water gun.

Further, both the bearing pad and the bearing seat are axially divided into half structures, and positioning pins are arranged between the bearing pad and the bearing seat.

Further, the locating pin is in a tight fit with the bearing bush and in a clearance fit with the bearing seat.

With the above scheme, the utility model has at least the following advantages: the water guide bearing is provided with a water tank, which can be lubricated by medium water, avoiding the accident of burning tiles caused by poor oil lubrication, and in the process of rolling the water guide bearing, it can The sediment is discharged through the water tank, so the bearing does not need to be sealed, the structure is simpler, and it is truly maintenance-free; the contact surface between the bearing pad and the bearing seat is a sphere, and the water guide bearing of this design has the function of self-aligning, and the contact surface is made of Surfacing stainless steel can avoid corrosion on the contact surface, thus better ensuring the automatic fine-tuning function of the bearing.

The above description is only an overview of the technical solution of the utility model. In order to understand the technical means of the utility model more clearly and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiment of the utility model with accompanying drawings as follows: rear.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

Referring to Fig. 1 and Fig. 2, a new maintenance-free water guide bearing proposed by the utility model includes a bushing 1, a bearing bush 2 and a bearing seat 3, and the bushing 1 is provided with a water tank 4 along the axial direction, and the cross section of the water tank 4 is Arc-shaped, rice-shaped, two-way spiral or dovetail, the material of the bushing 1 is polymer nylon, the contact surface 5 of the bearing bush 2 and the bearing seat 3 is a sphere, and the material of the contact surface 5 of the bearing bush 2 and the bearing seat 3 is Hardfacing stainless steel. The water guide bearing is equipped with a water tank 4, which can be lubricated by medium water, avoiding the accident of burning tiles caused by poor oil lubrication, and during the rolling process of the water guide bearing, the sediment can be discharged through the water tank 4, so the bearing does not Sealing is required, the structure is simpler, and it is truly maintenance-free; the contact surface 5 of the bearing bush 2 and the bearing seat 3 is a sphere, and the water guide bearing of this design has the function of self-aligning, and the contact surface 5 is made of surfacing stainless steel, which can avoid contact Surface 5 is corroded, thereby better guaranteeing the automatic fine-tuning function of the bearing.

The water guide bearing is provided with a tile temperature monitoring hole 6 which runs through the bushing 1, the bearing bush 2 and the bearing housing 3, and a temperature sensor is arranged in the tile temperature monitoring hole 6. It can better monitor the running condition of the water guide bearing.

In order to expand the scope of use of the water guide bearing, a water gun (not shown) is connected to the water tank 4 to facilitate the use of an external water source for lubrication.

Both the bearing bush 2 and the bearing seat 3 are axially divided into half structures, and the bearing bush 2 can be conveniently inspected, adjusted and replaced without dismantling the pump shaft and the impeller. There is a positioning pin 7 between the bearing bush 2 and the bearing seat 3. The positioning pin 7 is tightly fitted with the bearing bush 2 and has a clearance fit with the bearing seat 3, so that it can ensure that the bearing bush 2 will not follow the main shaft in the circumferential direction when the guide bearing is running. The rotation of the pump can also be fine-tuned within a certain range with the actual situation of the rotating part of the water pump to eliminate the overload of the bearing pad 2 caused by the poor alignment of the shaft system and the unbalanced force generated during operation, so that the bearing pad 2 is subjected to force balance.

To sum up, the utility model has the following advantages: 1. The unique design of the water tank 4 forms a stable water film to meet the operating requirements of different loads and speeds, and at the same time can remove sediment and save the sealing structure of the water guide bearing; 2. It avoids the tile burning accident caused by poor oil lubrication, realizes maintenance-free, no grease leakage, no environmental pollution, and is suitable for occasions with high water quality requirements; 3. The self-aligning installation method is simple and reliable, and stainless steel is added to the spherical surface The contact surface of the surfacing layer is 5 to prevent rust; 4. The structure is divided into half, and the positioning pin is positioned by 7. The tile body can be used up and down, which greatly increases the service life; 5. According to the use environment, it can be operated with external lubricating water, which expands the product range. range of use.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. It should be pointed out that for those of ordinary skill in the art, they can also do Several improvements and modifications are made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
