Abstract
The invention discloses a hammer lever sealing device comprising an air cylinder, a hammer lever, an upper guide sleeve, high pressure asbestos, a lower guide sleeve, a compression plate, a bolt and a screw, wherein the radial outer side of the hammer lever is provided with the upper guide sleeve, the high pressure asbestos and the lower guide sleeve, the upper guide sleeve is matched and linked with a flange; the air cylinder and the flange are fastened by using the screw; and the compression plate is fastened on the lower guide sleeve by using the bolt. By using the sealing device, the sealing function is effectively realized, the phenomena of shortage of engine power, increment of oil consumption, poor combustion of fuel in the air cylinder, exhaust smoking or air filter blow-by and the like caused by the air leakage of the air cylinder are controlled, noise pollution is reduced, and the service life of an assorted mechanism is prolonged.
Description
Technical field
The present invention relates to a kind of hammer stem seal arrangement.
Background technique
In the cylinder running, the cylinder seepage is the most common plant issue, and cylinder gas leakage can directly influence the performance characteristic and its usage economy of motor; Cause engine power not enough; Oil consumption increase, fuel are bad at cylinder combustion, smoking of the exhaust or air-strainer gas blowby, make the engine start difficulty when serious, even the engine operation balance is damaged; Abnormal vibrations often appears in running, quickens the wearing and tearing and the damage of distribution device.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure in order to solve the deficiency of existing technology, and working stability is reliable, the hammer stem seal arrangement of good sealing effect.
Technological scheme: in order to realize above purpose; A kind of hammer stem seal arrangement of the present invention, it comprises cylinder, hammer stem, flange, upper guide bush, high pressure asbestos, following guide pin bushing, platen, bolt and screw; The radial outside of described hammer stem is provided with upper guide bush, high pressure asbestos and following guide pin bushing; Described upper guide bush cooperates connection with flange, screw is with cylinder and secure, and bolt is fastened on down platen on the guide pin bushing.
Described hammer stem and upper guide bush adopt the mode of Spielpassung to connect.
Described flange and upper guide bush adopt the mode of interference fit to connect.
The material of described upper guide bush is bronze or brass.
Described flange adopts the mode of Spielpassung to connect with following guide pin bushing.
The described material of guide pin bushing down is bronze or 35 steel.
Beneficial effect: a kind of hammer stem seal arrangement that the present invention provides, through bolt is fastened on down platen on the guide pin bushing, when hammer stem moves to limit position; Platen will descend guide pin bushing to move up, and because of following guide pin bushing and flange employing Spielpassung, thereby make the high pressure asbestos be compressed; Flange screw high pressure asbestos; Realized the effect of sealing, it is not enough to have controlled the engine power that causes because of cylinder gas leakage, phenomenons such as oil consumption increase, fuel are bad at cylinder combustion, smoking of the exhaust or air-strainer gas blowby; Reduce noise pollution, increased the working life of assorting mechanism.
Description of drawings
Fig. 1 is a partial sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.
As shown in Figure 1, a kind of hammer stem seal arrangement of the present invention, it comprises: cylinder 1, hammer stem 2, flange 3, upper guide bush 4, high pressure asbestos 5, following guide pin bushing 6, platen 7, bolt 8 and screw 9.
The radial outside of described hammer stem 2 is provided with upper guide bush 4, high pressure asbestos 5 and following guide pin bushing 6, and described upper guide bush 4 cooperates connection with flange 3, and screw 9 is fastening with cylinder 1 and flange 3, and bolt 8 is with on the platen 7 fastening guide pin bushings 6 down.
Described hammer stem 2 adopts the mode of Spielpassung to connect with upper guide bush 4; Described flange 3 adopts the mode of interference fit to connect with upper guide bush 4; The material of described upper guide bush 4 is bronze or brass; Described flange 3 adopts the mode of Spielpassung to connect with following guide pin bushing 6, and the described material of guide pin bushing 6 down is bronze or 35 steel.
Because of the radial outside of hammer stem 2 is provided with upper guide bush 4, upper guide bush 4 mainly plays a part to lead, and prevents scratch hammer stem 2; Do when longitudinally moving to limit position when hammer stem 2, platen 7 will descend guide pin bushing 6 to move up, because of guide pin bushing 6 down adopts Spielpassung with flange 3; Thereby make high pressure asbestos 5 be compressed, flange 3 compresses high pressure asbestos 5, has realized the effect of sealing; It is not enough to have controlled the engine power that causes because of cylinder 1 gas leakage; Phenomenons such as oil consumption increase, fuel are bad at cylinder combustion, smoking of the exhaust or air-strainer gas blowby have reduced noise pollution, have increased the working life of assorting mechanism.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
