In addition, the engine trunnion shaft is provided with a driven gear 921 and a trunnion shaft balancing weight 922 for 92 coaxial groups, driven gear 921 is engaged with each other with actuation gear 915, and beat on the driven gear 921 and be carved with one second and align a mark 923 and a window 924, second to align mark 923 adjacent one another are with window 924, and see through window 924 and make first to align mark 916 and second and align mark 923 and can be in alignment with each other, to reach the demand of location.
Yet, said structure aligns mark 916 and second first and aligns mark 923 when being in alignment with each other, as shown in Figure 2, the first counter weight piece 913 can overlap each other with trunnion shaft balancing weight 922, so when assembling, must consider its two relative position relation again, so increase the inconvenience of assembling easily, be not very good.
The model utility content
The purpose of this utility model is to provide a kind of assembling to align improvement mechanism more easily.
The utility model adopts following technical characteristics to think the solution above-mentioned purpose.
An arrange in pairs or groups engine crankshaft and the engine trunnion shaft of structure-improved that align of the present utility model uses, wherein, engine crankshaft is provided with a counter weight piece, a bearing and an actuation gear for coaxial group, actuation gear comprises one first external diameter, bearing comprises one second external diameter, this second external diameter is greater than first external diameter of actuation gear, and the counter weight piece comprises that one first aligns mark.
In addition, trunnion shaft is provided with a trunnion shaft balancing weight and a driven gear for coaxial group, driven gear is engaged in above-mentioned actuation gear, driven gear also comprises that one second aligns a mark and a window, wherein window is adjacent to second and aligns mark and align mark corresponding to first, and sees through window and make second to align mark and be aligned in first and align mark.
Characteristic of the present utility model is that above-mentioned second aligns mark and be positioned at relatively a side away from the trunnion shaft balancing weight, the counter weight piece is ship anchor shape and comprises a crown portion and a shank portion, shank portion is connected in crown portion, and first aligns mark and be positioned at shank portion relatively away from a side of crown portion.
Therefore, by said structure, when assembling, counter weight piece and trunnion shaft balancing weight can not overlap each other, that is need when assembling, not consider counter weight piece and trunnion shaft balancing weight the relative position of each other relation again, align mark be in alignment with each other when location so align mark and second, can increase the convenience of assembling simultaneously first.
Above-mentioned shank portion can be provided with a crankpin by axle, and crankpin comprises an end face, and first align mark and be positioned at this end face.
In addition, first aligns mark can be a straight line, and draws and to be located on the counter weight piece, for example draws with instruments such as oil pen, paint and is located on the counter weight piece.Certainly, first aligns mark can also directly beat and be engraved on the counter weight piece, for example beat be carved into a groove mark and.Second aligns mark also can the aforementioned manner design.
The utility model has the advantages that aligning mark and second first aligns mark be in alignment with each other when location, can increase the convenience of assembling simultaneously.
