Technical field
The present invention relates to the crankshaft support structure of a kind of vertical output engine, when a kind of engine uses vertical output mode, it is possible to bear the larger axis crankshaft support structure to power, belong to engine apparatus technical field.
Background technology
In recent years, on the agricultural machinery such as small-sized Miniature cultivator used on higher and Small-sized Marine propeller, the engine using vertical output mode gradually increases, its reason is mainly, compared with traditional horizontal output mode, engine vertical output can make the drive mechanism between power and related agricultural machinery simplify, and advantageously reduces complete machine weight and cost, facilitates user to safeguard use.But, after being in plumbness due to engine crankshaft, the weight of flywheel and bent axle will increase an extra power axially downwards to crankshaft two end spring bearing, now crankshaft two end supporting construction is as still by the structure that horizontal output is identical, it is easy for causing body or side cover cracking, the phenomenon of rolling bearing damage, reliability when vertical output engine uses will be had a strong impact on.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point, thus a kind of simple in construction, assembling easy to process, easy, the crankshaft support structure of lower-cost vertical output engine are provided.
The technical scheme provided according to the present invention, the crankshaft support structure of a kind of vertical output engine includes body, side cover, flywheel, bent axle, balance axle and camshaft, it is characterized in that: body one end connects side cover, being provided with bent axle, balance axle and camshaft in body and side cover, balance axle and camshaft are positioned at the left and right sides of bent axle；The flywheel end of bent axle is supported by angular contact bearing and is connected in body, and the side cover end of bent axle is supported by plain thrust bearing and main bearing shell and is connected in side cover, and the flywheel end of bent axle stretches out body and connects flywheel；Balance axle is provided with the first balance gear, and the flywheel end of bent axle is provided with the second balance gear, the first balance gear and the engagement of the second balance gear and connects；Camshaft is provided with the second timing gears, and the side cover end of bent axle is provided with the first timing gears, the second timing gears and the engagement of the first timing gears and connects.
Further, it is provided with flywheel end oil sealing between flywheel end and the body of bent axle.
Further, it is provided with side cover end oil sealing between side cover end and the side cover of bent axle.
Further, bent axle, balance axle and camshaft are parallel to each other.
Further, balance axle two ends are connected in body and side cover by bearings respectively.
Further, camshaft two ends are connected in body and side cover by bearings respectively.
Compared with the prior art the present invention has the advantage that
Present configuration is simple, compact, reasonable, uses angular contact ball bearing to substitute former common ball bearing at crankshaft component flywheel end, sets up a plain thrust bearing, substantially increase the reliability of vertical output engine crankshaft supporting construction at side cover section main bearing shell；Organism internal structure is changed little, and assembling easy to process, easy, cost are relatively low.

Detailed description of the invention
The embodiment combined in accompanying drawing is further described by the present invention below:
As it is shown in figure 1, the invention mainly comprises body 1, side cover 2, flywheel 3, bent axle 4, balance axle 5 and camshaft 6.
Body 1 one end connects side cover 2, is provided with bent axle 4, balance axle 5 and camshaft 6 parallel to each other in body 1 and side cover 2, and balance axle 5 and camshaft 6 are positioned at the left and right sides of bent axle 4.
Balance axle 5 two ends are connected in body 1 and side cover 2 by bearings respectively, and camshaft 6 two ends are connected in body 1 and side cover 2 by bearings respectively.The flywheel end of bent axle 4 is supported by angular contact bearing 9 and is connected in body 1, and the side cover end of bent axle 4 is supported by plain thrust bearing 11 and main bearing shell 13 and is connected in side cover 2, and the flywheel end of bent axle 4 stretches out body 1 and connects flywheel 3.
Balance axle 5 is provided with the first balance gear 7A, and the flywheel end of bent axle 4 is provided with the second balance gear 7B, the first balance gear 7A and the second balance gear 7B engagement and connects, and is connected by the engagement of a pair balance gear and achieves balance axle 5 and the transmission of bent axle 4.
Camshaft 6 is provided with the second timing gears 8B, and the side cover end of bent axle 4 is provided with the first timing gears 8A, the second timing gears 8B and the first timing gears 8A engagement and connects, and is connected by the engagement of a pair timing gears and achieves camshaft 6 and the transmission of bent axle 4.
It is provided with flywheel end oil sealing 10 between flywheel end and the body 1 of described bent axle 4, is realized the sealing of the flywheel end of bent axle 4 by flywheel end oil sealing 10.
It is provided with side cover end oil sealing 12 between side cover end and the side cover 2 of described bent axle 4, is realized the sealing of the side cover end of bent axle 4 by side cover end oil sealing 12.
The present invention arranges angular contact ball bearing at crankshaft component flywheel end and substitutes former common ball bearing, a plain thrust bearing is set up at side cover point main bearing shell, thus considerably increase the whole crankshaft support structure ability to bear that flywheel and bent axle are conducted oneself with dignity in vertical direction, substantially increase the reliability of vertical output engine crankshaft supporting construction.Owing to the profile installation dimension of angular contact ball bearing is identical with common ball bearing, so the size of crankshaft-flywheel end correlated parts is without variation, the axial dimension of side cover is made to be varied from although side cover section sets up plain thrust bearing, but because the engine of vertical output is different from the connected mode of relevant outfitting tool, its side cover structure is just the most different from the side cover of horizontal output.The present invention has simple in construction, assembling easy to process, easy, lower-cost feature.
