Abstract
The present invention relates to a crank hole centrifugal type respirator which belongs to the technical field of machines. The crank hole centrifugal type respirator mainly utilizes the centrifugal force produced by the rotation of a crank to purify the oil mist discharged by the respirator of a small air compressor or the respirator of a small engine.
Description
Crank channel type respiration structure belongs to field of mechanical technique.The present invention is mainly the resuscitation apparatus of simplification, the non-extraneous pressure oil lubrication piston compressor of optimization and designs, and also can be applicable to the design of mini engine resuscitation apparatus.
When compressor or engine operation, because the gas blowby of piston ring, and reciprocating motion of the pistons, the air pressure in the crankcase is raise and fluctuation thereupon, Overall Power Consumption is increased.For solving this technical problem, common way is, in a certain position of casing a resuscitation apparatus is set, and also has employing to have axial bore on bent axle, has radial hole in addition and intersect with axial bore on equilibrium block, utilizes its centrifugal effect to control oil extraction.As opening among the clear 55-29077, be to have adopted such structure Japan Patent JP-spy.Test shows that its comprehensive effect is equivalent to the resuscitation apparatus of a certain position setting of casing.Because lubricant oil splashes in casing, it is higher that gas contains oil density, adopts general various resuscitation apparatuss, and the effect that suppresses oil extraction is all not really desirable.
Purpose of the present invention will improve oil gas separation exactly, the oil content in the resuscitation apparatus is controlled in the bottom line, and simplifies the manufacturing process of breathing structure greatly.
Fig. 1 is the plan view of structure of the present invention.
Fig. 2 is the side view of structure of the present invention.
The present invention is design like this and implements:
As shown in Figure 1, 2, crankshaft rotating direction ω makes a call to a hole A in the crankshaft counter balance upper edge, this hole and radial hole B(auxiliary hole) and axial bore C communicate, and C one end in hole directly is communicated with atmosphere, auxiliary hole B outer end is stopped up.On crankshaft counter balance, there are an auxiliary hole B and axial bore C to intersect, it is characterized in that stopping up the outer end of auxiliary hole B, have a tangential hole A and auxiliary hole B to intersect on the equilibrium block, the opening direction of tangential hole is opposite with sense of rotation, and its rotating locus is inclusive within the rotating locus of crankshaft counter balance.During crankshaft rotating, oil droplet is at first separated at the equilibrium block in A the place ahead, hole bump all the time, and the oil droplet that remains in can throw away bent axle by centrifugal action in the aperture near, and gas is then by aperture discharge crankcase.
The breathing structure of other pattern that the present invention is more traditional is simple, and good manufacturability is functional, oil drain quantity be Japan Patent JP-spy open the described breathing structure of clear 55-29077 1/10th.Solved the oil extraction problem of the resuscitation apparatus of single cylinder reciprocating piston machinery.
When being used for the design of mini engine, this structure also can be arranged on other running shaft.
