Abstract
The utility model proposes a kind of water pump shaft connecting bearings of outer ring with injection slot, including mandrel and outer ring, outer ring is coated on the outside of mandrel, rolling element is provided between mandrel and outer ring, outer ring is fixed in casing by interference fit, and outer ring outer wall has injection slot, and the injection slot is along the axially arranged of outer ring, sizing material can be accommodated in injection slot, the interference fit of outer ring and casing is strengthened by sizing material.Rolling element includes roller and steel ball, roller is installed between mandrel and outer ring by roller cage, and steel ball is installed between mandrel and outer ring by ball retainer, and outer ring both ends are respectively equipped with sealing ring, sealing ring inwall is attached at mandrel surface, and the position of injection slot is occupy between roller and steel ball.The bearing sets injection slot on outer ring, first carries out sizing material injection before water pump installation in injection slot, and the coefficient of friction of sizing material is higher than the outer surface of bearing, so as to improve the interference fit of bearing, effectively bearing can be prevented to move in the housing.
Description
Technical field
It the utility model is related to Production of bearing technology, more particularly to a kind of water pump shaft connecting bearings of outer ring with injection slot.
Background technology
Bearing outer ring is interference fit with housing, due to the rise case material expansion of operation temperature, outer ring and housing
The magnitude of interference can reduce, bearing is bearing certain responsive to axial force, relative movement will occur, and is mutually related pump with bearing
System will change, and ultimately result in water pump failure.
Utility model content
The purpose of this utility model is to provide a kind of water pump shaft connecting bearings of outer ring with injection slot, to prevent bearing from moving.
The utility model for solve its technical problem the technical scheme adopted is that
A kind of water pump shaft connecting bearings of outer ring with injection slot, including mandrel and outer ring, outer ring are coated on the outside of mandrel, mandrel
Rolling element is provided between outer ring, outer ring is fixed in casing by interference fit, wherein：
Outer ring outer wall has injection slot, and the injection slot can accommodate sizing material, by sizing material along the axially arranged of outer ring in injection slot
The interference fit of outer ring and casing is strengthened.
Rolling element includes roller and steel ball, and roller is installed between mandrel and outer ring by roller cage, and steel ball passes through
Ball retainer is installed between mandrel and outer ring, and outer ring both ends are respectively equipped with sealing ring, and sealing ring inwall is attached at mandrel table
Face, the position of injection slot are occupy between roller and steel ball.
The width of injection slot is 2.5mm~2.6mm, and its depth is 0.55~0.65mm, injection groove edge have straight line or
Circular arc chamfering side.
The utility model has the advantage of the bearing sets injection slot on outer ring, before water pump installation first in injection slot
Sizing material injection is carried out, the coefficient of friction of sizing material is higher than the outer surface of bearing, so as to improve the interference fit of bearing, passes through bearing
With the interference fit and sizing material of housing and the interference fit of housing, effectively bearing can be prevented to move in the housing.
Brief description of the drawings
Fig. 1 be the utility model proposes water pump shaft connecting bearings of the outer ring with injection slot structural representation.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines diagram and specific embodiment, and the utility model is expanded on further.
As shown in figure 1, the utility model proposes water pump shaft connecting bearings of the outer ring with injection slot include mandrel 1 and outer ring 2,
Outer ring is coated on the outside of mandrel, and rolling element is provided between mandrel and outer ring, and outer ring is fixed in casing by interference fit, outer ring
Outer wall has injection slot 3, and the injection slot can accommodate sizing material, by sizing material to outer ring and machine along the axially arranged of outer ring in injection slot
The interference fit of shell is strengthened.Rolling element includes roller 4 and steel ball 5, roller by roller cage 6 be installed in mandrel with it is outer
Between circle, steel ball is installed between mandrel and outer ring by ball retainer 7, and outer ring both ends are respectively equipped with sealing ring 8, sealing ring
Inwall is attached at mandrel surface, and the position of injection slot is occupy between roller and steel ball.The width of injection slot is 2.5mm~2.6mm,
Its depth is 0.55~0.65mm, and injection groove edge has straight line or circular arc chamfering side.The bearing sets injection slot on outer ring,
Sizing material injection is first carried out before water pump installation in injection slot, the coefficient of friction of sizing material is higher than the outer surface of bearing, so as to improve
The interference fit of bearing, by the interference fit and sizing material of bearing and housing and the interference fit of housing, it can effectively prevent axle
Hold and move in the housing.
For embodiment of above only to illustrate technical concepts and features of the present utility model, its object is to allow the skill of this area
Art personnel understand content of the present utility model and are simultaneously carried out, and can not limit the scope of protection of the utility model with this, all
The equivalent change or modification done according to the utility model Spirit Essence, it should all cover in the scope of protection of the utility model.
