Abstract
The present invention relates to a water pump bearing, and belongs to the technical field of bearing equipment. The water pump bearing comprises an outer ring, a core shaft, a double lip sealing ring, a ball retainer, column retainers, rolling columns and a steel ball, wherein the rolling column is arranged in the window hole of the column retainer, the steel ball is arranged in the pocket hole of the ball retainer, groove channels and rolling channels are processed on the outer ring and the core shaft, the steel ball rolls in the groove channel, the rolling column rolls in the rolling channel, the outer diameter of the double lip sealing ring is arranged in the sealing ring threaded groove of the outer ring, the inner diameter of the double lip sealing ring is connected with the core shaft, and the double lip sealing ring is made from a nitrile butadiene rubber. According to the water pump bearing of the present invention, the ball retainer, the column retainer and the double lip sealing ring are additionally arranged on the base of the existing bearing, such that the falling out of the rolling body during the installation and the disassembly is prevented, it is ensured that the bearing does not produce the oil leakage condition, and the invasion of external impurities is prevented; and the specified column end radial dynamic load of the present invention is increased by 25 KN compared with the specified column end radial dynamic load of the previously-designed structure, such that advantages of high bearing capacity, long service life, good rigidity, high rotation degree and the like are provided, and the failure rate is almost zero after the water pump bearing is used by customers.
Description
Technical field
The present invention relates to water bearing in pump, belong to bearing apparatus technical field.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.The subject matter that existing bearing on water pump exists is that bearing capacity is lower, bearing fault rate is higher, the life-span is short.
Summary of the invention
The object of the invention is to solve the deficiency that above-mentioned prior art exists, provide that a kind of reasonable in design, bearing capacity are high, the water bearing in pump of failure rate is low, long service life.
The present invention is achieved by the following technical solutions:
A kind of water bearing in pump, its special way is to comprise outer ring 91, mandrel 92, double-lip sealing ring 68, Ball Retainer 46, post retainer 26, roller 24 and steel ball 4, roller 24 is arranged in the fenestra of post retainer 26, steel ball 4 is arranged in the pocket hole of Ball Retainer 46, outer ring 91 and mandrel 92 are processed with raceway groove and raceway, roll in steel ball 4 raceway groove, roller 24 rolls on raceway, the external diameter of double-lip sealing ring 68 is installed in the seal ring age of a draught animal groove of outer ring 91, and the internal diameter of double-lip sealing ring 68 is connected with mandrel 92;
Described double-lip sealing ring 68 adopts nitrile rubber to make.
Water bearing in pump of the present invention, the basis of existing bearing has been set up Ball Retainer, post retainer and double-lip sealing ring, rolling element when mounting and dismounting bearing is prevented to drop out, also ensure that bearing is oil-proof, prevent the intrusion of foreign matter, the radial dynamic load rating of styletable 25KN larger than former project organization, has that bearing capacity is large, long service life, good rigidly, swing advantages of higher, and client uses rear rate of fault almost nil.
Accompanying drawing explanation

In figure: 4, bearing, 24, roller, 26, post retainer, 46, Ball Retainer, 68, double-lip sealing ring, 91, outer ring, 92, mandrel.
Embodiment
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for being described in further detail formation of the present invention.
The water bearing in pump of the present embodiment, comprise outer ring 91, mandrel 92, double-lip sealing ring 68, Ball Retainer 46, post retainer 26, roller 24 and steel ball 4, roller 24 is arranged in the fenestra of post retainer 26, steel ball 4 is arranged in the pocket hole of Ball Retainer 46, outer ring 91 and mandrel 92 are processed with raceway groove and raceway, roll in steel ball 4 raceway groove, roller 24 rolls on raceway, the external diameter of double-lip sealing ring 68 is installed in the seal ring age of a draught animal groove of outer ring 91, the internal diameter of double-lip sealing ring 68 is connected with mandrel 92, and described double-lip sealing ring 68 adopts nitrile rubber to make.
The effect of retainer:
A. retainer is equally spaced by rolling element, with prevent bearing in the running rolling element collide with each other;
B. retainer guides and rolls and drive rolling element to rotate;
C. in separation property bearing, rolling element together with a collar combination, is formed assembly parts by retainer, drops out to prevent the rolling element when mounting and dismounting bearing.
The effect of seal ring: seal ring adopts the radial direction contact sealing through optimal design, to guarantee the intrusion of the oil-proof and foreign matter of bearing.
Mandrel operates usually together with belt pulley, impeller, water seal drive fit, and outer ring becomes transition fit with water pump pump case usually, play supporting role.
Rolling element (steel ball, roller) is usually arranged in the intercropping rolling motion of two lassos equably in bearing by retainer, its shape, size and number directly affect load carrying capacity and the usability of bearing.
Water pump bearing adopts disposable lubricating grease " all the life " to lubricate, and therefore lubricates the working life directly having influence on bearing.Select 2-3# lithium grease just can meet lubricating requirement under normal circumstances, the amount of inserting of lubricating grease is the 1/4-1/2 of bearing interior space.
The unspecified content of the present invention is prior art, and those skilled in the art can obtain inspiration from the present embodiment and prior art, carries out distortion and obtains other embodiment.Therefore, protection scope of the present invention should be determined according to the protection domain of claim.
