Description
Technical field
The utility model is related to field of bearings or sprocket wheel field, more particularly to a kind of Novel chain wheel bearing.
Background technology
Conventional sprocket shaft bearing is outer ring rotation, bears radial load by outer ring outer diameter, thus want at work
The design of sprocket shaft bearing having different from conventional deep groove ball bearing is sought, this class bearing there are following several knots under normal conditions
Structure：Single-row ball-bearing, row ball bearing, double-row angular contact bal bearing.The class bearing only increases steel ball when bearing compared with big load
Diameter and steel ball quantity could improve the bearing capacity of bearing, and the volume for resulting in bearing in this way becomes larger, and not only wastes material, processing
Labor intensive, and fork truck volume will also increase, and cause the waste of bigger, can not meet the demand in market.
A kind of patent of sprocket shaft bearing, Authorization Notice No. CN206943214U propose a kind of sprocket shaft bearing, wherein outer ring
It is packed into from one end of housing, the outer circle of outer ring is matched with the macropore of the inner bore of step of housing, and a side end face of outer ring leans against platform
At the inner face of rank endoporus, inner ring is arranged in the endoporus of outer ring.It is equipped with corresponding ditch in the outer circle of inner ring, the endoporus of outer ring
Road, steel ball are arranged in raceway groove.Since the patent is packed into housing in sprocket wheel, make cannot achieve in the structure of some limited spaces
's.In addition 2 raceway grooves are processed in inner ring outer surface, increases processing cost and the difficulty of assembly.
Invention content
In response to the deficiencies in the existing technology, the utility model provides a kind of Novel chain wheel bearing, can facilitate installation,
Improve equipment precision.
The utility model is to realize above-mentioned technical purpose by following technological means.
A kind of Novel chain wheel bearing, including outer ring, inner ring, steel ball and retainer；It is chain odontoid, institute on the outside of the outer ring
The outside for stating inner ring is equipped with arc groove, and steel ball described in biserial, biserial are fixed respectively by retainer between the outer ring and inner ring
The steel ball is symmetrically mounted in the arc groove of inner ring.
Further include sealing ring, the sealing ring is mounted between outer ring and inner ring, and positioned at the both ends of the surface of outer ring and inner ring.
The radius of the arc groove is R, a diameter of d of the inner ring endoporus, diameter and the circle of the inner ring endoporus
The radii ratio of arc slot is：d：R=1.5：2.5.
The retainer is whole " streamlined ".
The beneficial effects of the utility model are：
1. Novel chain wheel bearing described in the utility model is equipped with arc groove, by steel described in biserial by the outside of inner ring
Ball is symmetrically mounted in the arc groove of inner ring, and flange of the steel ball installation not between by the groove of traditional design may be implemented and limited
System.Steel ball installation number can also be increased, bearing capacity substantially improves.
2. Novel chain wheel bearing described in the utility model is equipped with arc groove, by steel described in biserial by the outside of inner ring
Ball is symmetrically mounted in the arc groove of inner ring, may be implemented that steel ball is facilitated to install, and can all be pacified steel ball from the side of inner ring
Dress realizes Fast Installation.
3. Novel chain wheel bearing described in the utility model is equipped with arc groove by the outside of inner ring, Double-row ball is symmetrical
In arc groove, due to there is no the limitation of flange, extra space that can increase the space of trapped fuel fat between Double-row ball,
Increase service life of the sprocket shaft bearing under bad working environments.
Description of the drawings
Fig. 1 is Novel chain wheel bearing front view described in the utility model.
In figure：
The outer rings 1-；2- inner rings；3- steel balls；4- retainers；5- sealing rings；6- arc grooves.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is further described the utility model, but the guarantor of the utility model
Shield range is not limited to this.
As shown in Figure 1, Novel chain wheel bearing described in the utility model, including outer ring 1, inner ring 2, steel ball 3 and retainer
4；1 outside of the outer ring is chain odontoid, and the outside of the inner ring 2 is equipped with arc groove 6, passes through between the outer ring 1 and inner ring 2
Retainer 4 fixes steel ball 3 described in biserial respectively, and steel ball 3 is symmetrically mounted in the arc groove 6 of inner ring 2 described in biserial.Such as Fig. 1 institutes
Show, for the convenience of installation, the notch on the left side is more than the right between outer ring 1 and inner ring 2, mainly facilitates the need of installation
It asks.
In addition, Novel chain wheel bearing described in the utility model can use whole " streamlined " type retainer 4 to replace architomia
Ribbon retainer 4, retainer 4 bear heavily loaded ability and greatly improve.Novel chain wheel bearing described in the utility model, internal basis
The demand of bearing capacity using whole " streamlined " type retainer 4 between steel ball, can in this way may be used with design arrangement more steel ball 3
So that steel ball quantity is not limited by seperated ribbon retainer 4.
The radius of the arc groove 6 be R, a diameter of d of 2 endoporus of the inner ring, the diameter of 2 endoporus of the inner ring with it is described
The radii ratio of arc groove 6 is：d：R=1.5：2.5.Due to not having the limitation of flange between Double-row ball, extra space can
To increase the space of trapped fuel fat, increase service life of the sprocket shaft bearing under bad working environments.
Novel chain wheel bearing described in the utility model is equipped with arc groove, by steel ball described in biserial by the outside of inner ring
It is symmetrically mounted in the arc groove of inner ring, flange of the steel ball installation not between by the groove of traditional design may be implemented and limited.
Steel ball installation number can also be increased, bearing capacity substantially improves, and may be implemented that steel ball is facilitated to install, can be with from the side of inner ring
All steel ball is installed, realizes Fast Installation.
In addition, further including sealing ring 5 to reach water proof and dust proof effect, the sealing ring 5 is mounted on outer ring 1 and inner ring 2
Between, and positioned at the both ends of the surface of outer ring 1 and inner ring 2.
The embodiment is the preferred embodiment of the utility model, but the utility model is not limited to above-mentioned embodiment party
Formula, without departing substantially from the substantive content of the utility model, those skilled in the art can make any apparent
Improvement, replacement or modification belong to the scope of protection of the utility model.
