Abstract

The utility model discloses a rolling bearing, by bearing inner race, bearing inner race, sealing washer and a plurality of steel ball constitute, bearing inner race arranges bearing inner race's inside in, bearing inner race's inner wall and bearing inner race's outer wall all set up the roll track, the steel ball equipartition is between bearing inner race and the respective roll track of bearing inner race, semi -retaining frame is cup jointed respectively to the outside both sides of steel ball, rivet through the rivet between the semi -retaining frame of both sides, two sealing washers set up respectively both sides semi -retaining frame 's the outside and place bearing inner race in and bearing inner race between, the utility model discloses an in integrating into bearing inner race with the inside axle sleeve of bearing inner race in the existing design, do not need to process in addition the axle sleeve, need not consider interference fit's between bearing inner race and the axle sleeve problem yet, consequently improved the yield, and reduced because of the running noise that bearing inner race and axle sleeve matching problem arouse, reduced the wear rate, improved life, therefore reduced manufacturing cost yet.

Description

A kind of rolling bearing

Technical field

The utility model is related to bearing applied technical field and in particular to a kind of rolling bearing.

Background technology

The solution of the drinking water pump bearing system on existing market is by bearing, axle sleeve and electric machine main shaft is supporting makes With problem therein is that there is interference fit between bearing inner race and axle sleeve, and the processing dimension of axle sleeve and precision directly affect axle The service life held and running noise, therefore require very high, machined surface difficulty is big, and installation process is easily made to processing precise degree Become workpiece damage, high processing costs.

Utility model content

The purpose of this utility model aims to provide a kind of rolling bearing, overcomes the deficiencies in the prior art, reduces difficulty of processing, Improving yield rate and the service life of rolling bearing, thus reducing production cost, increasing the benefit.

For achieving the above object, rolling bearing of the present utility model, by bearing outer ring, bearing inner race, sealing ring and some Steel ball is constituted, and bearing inner race is placed in the inside of bearing outer ring, and the inwall of bearing outer ring and the outer wall of bearing inner race are respectively provided with rolling Track, steel ball is distributed between bearing outer ring and the respective roller track of bearing inner race, and steel ball both sides external is socketed half guarantor respectively Hold frame, riveted by rivet between half retainer of both sides, at two, sealing ring is respectively provided at both sides the outer of half retainer Side is placed between bearing outer ring and bearing inner race.

Rolling bearing of the present utility model compared with prior art has following excellent effect：The axis of rolling of the present utility model Hold, the axle sleeve within existing design middle (center) bearing inner ring is integrated in bearing inner race, is not required in addition process axle sleeve, without consideration Between bearing inner race and axle sleeve, the problem of interference fit, therefore improves yield rate, and decreases because of bearing inner race and axle sleeve Join the running noise caused by problem, reduce wear rate, improve service life, thereby also reduce production cost.

Brief description

Fig. 1 is the partial sectional view of the utility model rolling bearing.

Wherein：1 is bearing outer ring, and 2 is bearing inner race, and 3 is sealing ring, and 4 is steel ball, and 5 is half retainer, and 6 is rivet.

Specific embodiment

Below in conjunction with the accompanying drawings rolling bearing of the present utility model is described in further detail.

Rolling bearing shown in Fig. 1, is made up of bearing outer ring 1, bearing inner race 2, sealing ring 3 and some steel balls 4, in bearing Circle 2 is placed in the inside of bearing outer ring 1, and the outer wall of the inwall of bearing outer ring 1 and bearing inner race 2 is respectively provided with roller track, steel ball 4 It is distributed between bearing outer ring 1 and the respective roller track of bearing inner race 2, steel ball 4 both sides external is socketed half retainer 5 respectively, Riveted by rivet 6 between half retainer 5 of both sides, at two, sealing ring 3 is respectively provided at both sides the outside of half retainer 5 It is placed between bearing outer ring 1 and bearing inner race 2.
