Description
Technical field
The utility model relates to a kind of vertical shaft single cylinder diesel, particularly a kind of vertical shaft single cylinder diesel engine lubrication system.
Background technique
At present, in vertical shaft single cylinder diesel, its lubrication system mainly comprises two kinds, one is splash lubrication, a kind of is pressure lubrication, and for most of motor, in order to meet the demand of its lubrication, rotor engine oil pump is often adopted to carry out pressure lubrication kinematic pair, lubricating system is although it is so feasible, but, pressure lubrication needs to use oil pump, cause like this occupying larger space in motor, simultaneously, owing to being vertically shafted engine, often need the gravity overcoming bent axle, the loss of power is just larger, add the loss of oil pump, power is made to have larger loss.
Model utility content
The purpose of this utility model is just to provide a kind of vertical shaft single cylinder diesel engine lubrication system of saving space, high lubricating effect.
The purpose of this utility model is realized by such technological scheme, a kind of vertical shaft single cylinder diesel engine lubrication system, comprise casing, bent axle is vertically installed with in casing, described bent axle is provided with oil inlet hole, be positioned at bottom half and be provided with the crankshaft installed portion be wholely set with casing in described casing, the lower end of described bent axle is through crankshaft installed portion, bearing shell bent axle being provided with and blocking oil inlet hole is positioned between the lower end of described bent axle and crankshaft installed portion, described crankshaft installed portion and bearing shell are interference fit, described bearing shell and bent axle lower end are Spielpassung, described bearing shell inwall is provided with helical oil groove, the oil inlet passage being communicated with cabinets cavity and bearing shell bottom is provided with in the bottom in described crankshaft installed portion.
In order to filter the impurity in machine oil, the bottom of described casing is provided with oil filter screen, one end of described oil filter screen is communicated with described oil inlet passage.
In order to prevent leakage of oil, between the lower end and casing of described bent axle, be provided with oil sealing.
Owing to have employed technique scheme, the utility model has structure advantage simple, cheap for manufacturing cost, adopt it not only can reduce lubrication system and inside contract the space taken at casing, but also make lubrication effect better, simultaneously, also reduce the loss of power, improve the power of motor.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the rear view of Fig. 1;
Fig. 3 is bearing shell deployed configuration schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as Fig. 1, 2, shown in 3, a kind of vertical shaft single cylinder diesel engine lubrication system, comprise casing 1, bent axle 2 is vertically installed with in casing 1, described bent axle 2 is provided with oil inlet hole 3, the crankshaft installed portion 4 being provided with bottom casing 1 and being wholely set with casing 1 is positioned in described casing 1, the lower end of described bent axle 2 is through crankshaft installed portion 4, be positioned at the bearing shell 5 bent axle 2 being provided with and blocking oil inlet hole 3 between the lower end and crankshaft installed portion 4 of described bent axle 2, described crankshaft installed portion 4 is interference fit with bearing shell 5, described bearing shell 5 is Spielpassung with bent axle 2 lower end, described bearing shell 5 inwall is provided with helical oil groove 6, the oil inlet passage 7 being communicated with casing 1 inner chamber and bearing shell 5 bottom is provided with in the bottom in described crankshaft installed portion 4.
In the utility model, when machine oil face bottom casing 1 is higher than bearing shell 5, machine oil enters into bearing shell 5 bottom by oil inlet passage 7, the rotation of bent axle 2 makes machine oil be risen vertically by the helical oil groove 6 on bearing shell 5 inwall, when helical oil groove 6 rotates to time corresponding with oil inlet hole 3, machine oil in helical oil groove 6 enters in oil inlet hole 3, then shaft neck accumulation is reached, under the influence of centrifugal force, machine oil is by the oil leak hole lubrication connnecting rod big end end bearing shell of crankshaft journal, unnecessary machine oil just splash lubrication connecting rod small end under the influence of centrifugal force, the parts such as bearing and gear.
Further, in order to keep the cleaning of machine oil, prevent impurity from causing damage to bent axle, the bottom of described casing 1 is provided with oil filter screen 8, one end of described oil filter screen 8 is communicated with described oil inlet passage 7.
In order to prevent lubricating oil leakage, between the lower end and casing 1 of described bent axle 2, be provided with oil sealing 9.
