Abstract
The utility model aims at providing a novel internal-combustion engine balance shaft bearing hole structure which is characterized in that a balance shaft bearing is directly arranged on an internal-combustion engine body and is axially positioned by a bolt.
Description
Technical field
The utility model relates to a kind of internal-combustion engine balance shaft bearing hole structure, belongs to field of internal combustion engine.
Background technique
At present, the balance shaft bearing of the single-cylinder engine on the market all is installed on as Fig. 1, in the bearing support shown in Figure 2 (2), use back-up ring (3) location then, be installed on bolt on the bolt hole (4) in internal combustion (IC) engine airframe (1) balance shaft bearing seat hole with two more at last, it when adopting this kind installation method the requirement of satisfying trunnion shaft two ends coaxality, need in the strict guarantee bearing support, the outer ring coaxality, this has just increased the difficulty of processing of bearing support, simultaneously because bearing support is adopted two bolt, the raising that this has just restricted manufacturing efficiency has increased cost of production.
Summary of the invention
For addressing the above problem, we have carried out adjusting again to the dimensional chain of the trunnion shaft of internal combustion (IC) engine airframe, the size and the position in the balance shaft bearing seat hole by changing internal combustion (IC) engine airframe, directly with Bearing Installation on internal combustion (IC) engine airframe, and bearing is carried out axially locating with a screw, so just saved bearing support (2), back-up ring (3) and a bolt, this has just improved manufacturing efficiency greatly, has reduced cost of production.
Description of drawings
Accompanying drawing 1 is existing design of part figure.
Accompanying drawing 2 is existing design of part A-A sectional view.
Accompanying drawing 3 is the utility model structural drawing.
Accompanying drawing 4 is the utility model structure B-B sectional view.
Embodiment
Further describe below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3,4 pairs of the utility model of accompanying drawing: the diameter of axle size in the balance shaft bearing seat hole of internal combustion (IC) engine airframe (1) directly is processed into the installation dimension that bearing requires, make bearing hole (6), an axially locating screw hole (5) in the processing of the bearing hole outside.
Claims (1)
1, a kind of internal combustion engine balance shaft bearing hole structure, its structure characteristic is: the balance shaft bearing hole (6) on the internal combustion (IC) engine airframe (1) is directly used in the installation balance shaft bearing, and with a screw that is installed on the bearing positioning screw hole (5) bearing is carried out axially locating.
