Abstract
The utility model is related to a kind of GI87m housings of bicircular arcs structure, which includes pot shell ontology, and pot shell ontology is cylinder, is internally provided with cavity, three alleys are divided into cavity；The side in the section of alley is made of the identical circular arc of two sections of radiuses, and two sections of circular arcs are respectively circular arc A and circular arc B, the center of circle O of circular arc A1, the center of circle O of circular arc B2, center of circle O1With center of circle O2It is misaligned.The utility model has the beneficial effects that：The utility model improves the deficiency in existing design by the way that existing single arc structure is changed to bicircular arcs structure, it is 2 so that its stress point is increased by original 1, stressing conditions are disperseed significantly, by to housing interior optimization, reaching reduces raceway contact stress, promotes the effect of raceway service life.
Description
Technical field
The utility model is related to housing fields, and in particular to a kind of GI87m housings of bicircular arcs structure.
Background technology
Important component in housing auto parts.The GI87 nodal patterns that existing batch uses, in practice due to
The nodal pattern is single circular arc, and raceway depression problem easily occurs in stress concentration when causing by compared with big load.Three ball pin of existing nodal pattern and rolling
Road is all single arc structure, and the two contact position is a point, is assemblied in when being run on vehicle, is located at the point of raceway center
It is acted on by larger pressure, causes raceway to be recessed under chronic stress effect, what which shook when vehicle may be caused to accelerate asks
Topic.
Utility model content
The utility model solves above-mentioned deficiency in the prior art, provides a kind of tri- column slots of GI87m of bicircular arcs structure
Shell improves the deficiency in existing design, by housing by the way that existing single arc structure is changed to bicircular arcs structure
Interior optimization, reaching reduces raceway contact stress, promotes the effect of raceway service life.
Technical solution adopted by the utility model to solve its technical problems is：Tri- columns of GI87m of this bicircular arcs structure
Pot shell, the structure include pot shell ontology, and pot shell ontology is cylinder, is internally provided with cavity, three alleys are divided into cavity；Ball
The side in the section in road is made of the identical circular arc of two sections of radiuses, and two sections of circular arcs are respectively circular arc A and circular arc B, the center of circle of circular arc A
O1, the center of circle O of circular arc B2, center of circle O1With center of circle O2It is misaligned.
The center of circle O1With center of circle O2Angle ∠ O between the intersection points B of two circular arcs1BO2It is 0 ° -25 °, is with 20 °
Preferably.
The utility model has the beneficial effects that：The utility model by existing single arc structure by being changed to bicircular arcs structure
Improve the deficiency in existing design, it is 2 so that its stress point is increased by original 1, has disperseed stressing conditions significantly, has passed through
To housing interior optimization, reaching reduces raceway contact stress, promotes the effect of raceway service life.

Reference sign：1. pot shell ontology；2. cavity；3. alley；4. circular arc A；5. circular arc B；.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in the figure：A kind of GI87m housings of bicircular arcs structure, the structure include pot shell ontology 1, pot shell ontology 1
For cylinder, it is internally provided with cavity 2, three alleys 3 are divided into cavity 2；The side in the section of alley 3 is identical by two sections of radiuses
Circular arc is constituted, and two sections of circular arcs are respectively circular arc A 4 and circular arc B 5, the center of circle O of circular arc A 41, the center of circle O of circular arc B 52, center of circle O1
With center of circle O2It is misaligned.The center of circle O1With center of circle O2Angle ∠ O between the intersection points B of two circular arcs1BO2It is 0 ° -25 °, with
20 ° are advisable.
When in use (as shown in figs. 4 and 6), the utility model changes bicircular arcs alley by original single circular arc alley, the knot
It is two that the stress point of structure alley is increased by original one, and the direction of stress is also disperseed, can effectively avoid alley by
Stress is excessive to lead to depression problem, prolongs the service life, and improves using effect.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
