Description
Technical field
The present invention relates to cylinder block field, more particularly to a kind of cylinder block main shaft bearing structure.
Background technology
Existing cylinder block main bearing seat is to carry out longitudinal register by the positioning spigot of bearing cap side two.Such as Fig. 1 and Fig. 2 institutes
Show, the both ends of cylinder block main bearing seat 1 are provided with positioning spigot 2, while also are provided with positioning spigot, Ran Houtong at the both ends of main beating cap 3
Cross that Main bearing bolt 5 puts Main bearing bolt packing ring 4 and main beating cap 3 is tightened on cylinder block main bearing seat 1.I.e. bearing cap leads to
To cross and be bolted on bearing block, bearing cap both sides are provided with positioning spigot, and bearing block both sides are again provided with positioning spigot, and two
By coordinating, limitation bearing block moves positioning spigot to both sides.Such a positioning method, there are two shortcomings：
1. do not position axially.
2. due to needing to set positioning spigot at cylinder body bearing seat both ends, therefore need to increase material in the position to process
Positioning spigot, therefore the increase of cylinder block overall weight is a lot, while processing cost significantly improves.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of cylinder block main shaft bearing structure, positioned by guide, registration, mitigate gas
Cylinder body weight.
To achieve the above object, the invention provides a kind of cylinder block main shaft bearing structure, including：Main bearing seat, itself and gas
Cylinder body is integrally formed, and two side positions of main bearing seat hollow out；Main beating cap, it is bolted on main bearing seat；And
Guide, its both ends are plugged in the position of the bolt hole alignment of main bearing seat and main beating cap respectively, and bolt passes through guide.
Preferably, the both sides that hollow out of main bearing seat form connection wall.
Preferably, the both sides junction of connection wall and main bearing seat is provided with the excessive fillet of indent.
Preferably, excessive fillet includes the first fillet and the second fillet being engaged togather, the arc radius of the first fillet
More than the arc radius of the second fillet.
Compared with prior art, the present invention has the advantages that：Pass through the bolt in main bearing seat and main beating cap
The position of hole alignment sets guide, and main bearing seat and main beating cap are positioned by guide, ensures that main beating cap any direction will not
It is mobile, it is accurately positioned, while the material of main bearing seat both sides can be saved, mitigate weight.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figures 3 to 5, according to a kind of cylinder block main shaft bearing structure of the specific embodiment of the invention, including main shaft
Bearing 10, main beating cap 20 and guide 40, wherein main bearing seat 10 and cylinder body by integral forming, the both sides position of main bearing seat 10
Put and hollow out, main beating cap 20 is fixed on main bearing seat 10 by bolt 30, and the both ends of guide 40 are plugged in main bearing seat respectively
10 and main beating cap 20 bolt hole alignment position, bolt 30 passes through guide 40.
In such scheme, by setting guide 40 in the position that main bearing seat 10 and the bolt hole of main beating cap 20 are aligned,
Main bearing seat 10 and main beating cap 20 are positioned by guide 40, can save the positioning of main bearing seat 10 and the both sides of main beating cap 20
Seam, therefore the material of the both sides of main bearing seat 10 can be removed, for six cylinder machines, there are 7 main bearing seats, and each main bearing seat
Both ends can remove material, therefore can remove material to the position at 14, so main screw lift can be reduced effectively.For guide
40 setting, it can drill to form reaming 101 for inserting in the position that main bearing seat 10 and the bolt hole of main beating cap 20 are aligned
Guide 40 is filled, such guide 40 can guarantee that any direction of main beating cap 20 will not move, be accurately positioned.
As a kind of preferred embodiment, the both sides that hollow out of main bearing seat 10 form connection wall 102.
As a kind of preferred embodiment, the both sides junction of connection wall 102 and main bearing seat 10 is provided with the excessive circle of indent
Angle.
As a kind of preferred embodiment, excessive fillet includes the first fillet 103 and the second fillet 104 being engaged togather,
The arc radius of first fillet 103 is more than the arc radius of the second fillet 104.Because main bearing seat is main force part in main shaft
The link position of bearing and connection wall 102, as shown in figure 5, using big R fillets (the first fillet close to the position of main bearing seat 1
103) transition, it is secondary force part, using small R fillets (second to reduce stress, and close to the crossover position of connection wall 102
Fillet 104) transition, it thus can accurately ensure the structural strength of cylinder block main bearing seat.
To sum up, the cylinder block main shaft bearing structure of the present embodiment, passes through the bolt hole in main bearing seat 10 and main beating cap 20
The position of alignment sets guide 40, and main bearing seat 10 and main beating cap 20 are positioned by guide 40, ensures that main beating cap 20 is any
Direction will not move, and be accurately positioned, while can save the material of the both sides of main bearing seat 10, mitigate cylinder body weight.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
