Description

Water pump bearing

Technical Field

The utility model belongs to the bearing field, concretely relates to water pump bearing.

Background

The bearing is a component for fixing and reducing the friction coefficient of load in the mechanical transmission process, and can be used for reducing the friction coefficient in the power transmission process and keeping the central position of the shaft fixed when other components move relative to each other on the shaft. The bearing is an important part in the modern mechanical equipment and plays a role of supporting the rotating body.

The water pump bearing is one of the bearings, and is generally used on an engine in the core of a motor vehicle, and the research direction of the motor vehicle engine at present is high rotating speed and high load, so that higher performance requirements are put on the water pump bearing. The main problems of the existing bearing used on the water pump are that the bearing cannot resist high temperature, the bearing capacity is low, the failure rate of the bearing is high, and the service life is short.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a water pump bearing, the reducible condition of leaking, and each part is connected closely in guaranteeing the bearing, and high temperature resistant prolongs the life of bearing.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides a water pump bearing, the bearing includes dabber, outer lane, a plurality of roller, mated water seal and gets rid of the water ring, the outer lane cover is established outside the dabber, form the cavity that is used for holding the roller between dabber and the outer lane, be equipped with in the dabber and be used for intercommunication cavity and external ventiduct, a plurality of rollers encircle the dabber setting along circumference, dabber and outer lane rotate through the roller and connect, the tip that the outer lane was located to the water seal is connected with the dabber, get rid of the water ring and locate the outside of outer lane and be connected with the dabber.

The retainer for fixing the roller is arranged in the cavity, so that the roller can be prevented from irregularly moving when the mandrel rotates, and the outer ring and the mandrel are dislocated.

And an inner slide way for the rollers to roll is arranged on the inner side wall of the outer ring.

And an outer slideway for the rollers to roll is arranged on the outer side wall of the mandrel.

The water throwing ring comprises an annular body, a sleeve and a water throwing plate which are coaxially arranged, the sleeve is arranged in the middle of the annular body, a central hole matched with the mandrel penetrates through the center of the annular body and the center of the sleeve, the water throwing plate is arranged on the outer surface of the annular body, and the water throwing plate is arranged around the sleeve and extends outwards. When the bearing works, one end of the mandrel, which is provided with the water throwing ring, is adjacent to the inner cavity of the water pump, and water is thrown out by the water throwing ring, so that the problem that the bearing is damaged because the water enters the space between the main shaft and the outer ring from the water seal, the water is obliquely thrown out by the water throwing plate, the water throwing direction is increased, and the water throwing efficiency is improved.

A plurality of first water outlet grooves are formed in the outer surface of the annular body along the radial direction, and a plurality of second water outlet grooves are formed in the outer surface of the water throwing plate along the length direction. The first water outlet groove and the second water outlet groove are used for water outlet.

And a through hole communicated with the outside is formed in the joint of the water throwing plate and the sleeve.

The second water outlet groove is communicated with the through hole. Water can enter the second water outlet groove through the through hole and then is thrown out by the water throwing plate.

The outer diameter of the annular body is larger than the diameter of a circle formed by the free end of the water throwing plate. The annular body can play and block the effect, can avoid the water that the toper was thrown away a water drum and throws away to cross the annular body.

The depth of the first water outlet groove is gradually reduced from inside to outside, and the depth of the second water outlet groove is gradually reduced from inside to outside, so that water can be gradually thrown out in a thin line, and the water is prevented from splashing in a large range.

And a filter screen is arranged in the air duct. When the valve works, the valve starts to generate heat and rise temperature due to work, and gas expanded due to high temperature in the cavity can be discharged to the outside from the ventilation channel, so that the pressure in the cavity is reduced, the damage and the aging of parts near the water pump bearing are avoided, meanwhile, a gap between the water seal and the outer ring can be avoided, a gap is formed between the water seal and the mandrel, the leakage of lubricating grease smeared on the wall surface around the cavity is prevented, and the normal work of the water pump bearing is ensured. The filter screen is suitable for filtering pollutants outside the cavity, and at the moment, the filter screen can effectively prevent external pollutants, particularly large-size pollutants, from entering the cavity through the air passage to be smeared on lubricating grease.

The utility model discloses install in the water pump, at the water pump during operation, the dabber can rotate at a high speed, roller and dabber this moment, can take place relative rotation between roller and the outer lane, the friction is heated, in order to avoid the wearing and tearing between each part, make each part can normal operation, lubricating grease can be paintd at the wall of cavity generally, lubricating grease can evaporate because of high temperature, and then make the atmospheric pressure in the cavity rise, the ventiduct can in time discharge the lubricating grease of evaporation, it is inseparable to make to connect between each part, get rid of the water ring and can avoid water to enter into between main shaft and the outer lane from the water seal, lead to the bearing to damage.
