Abstract
The utility model discloses a hammer lever sealing device which comprises 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 through the screw; and the compression plate is fastened on the lower guide sleeve through the bolt. According to the sealing device, a 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 service life of an assorted mechanism is prolonged.
Description
Technical field
The utility model relates to a kind of hammer stem seal arrangement.
Background technique
In the cylinder running, the cylinder seepage is the most common plant issue, cylinder gas leakage can directly affect 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, accelerates wearing and tearing and the damage of distribution device.
The model utility content
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, to provide a kind of simple in structure, 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 described in the utility model, it comprises cylinder, hammer stem, flange, upper guide bush, high pressure asbestos, lower guide pin bushing, platen, bolt and screw, the radial outside of described hammer stem is provided with upper guide bush, high pressure asbestos and lower guide pin bushing, described upper guide bush cooperates connection with flange, screw is fastening with cylinder and flange, and bolt is fastened on platen on the lower 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 and lower guide pin bushing adopt the mode of Spielpassung to connect.
The material of described lower guide pin bushing is bronze or 35 steel.
Beneficial effect: a kind of hammer stem seal arrangement that the utility model provides, by bolt is fastened on platen on the lower guide pin bushing, when hammer stem moves to limit position, platen moves up lower guide pin bushing, because of lower guide pin bushing and flange employing Spielpassung, thereby so that the high pressure asbestos are 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, oil consumption increases, fuel is bad at cylinder combustion, the phenomenons such as smoking of the exhaust or air-strainer gas blowby have reduced noise pollution, have increased the working life of assorting mechanism.
Description of drawings
Fig. 1 is partial sectional view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of hammer stem seal arrangement described in the utility model, it comprises: cylinder 1, hammer stem 2, flange 3, upper guide bush 4, high pressure asbestos 5, lower 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 lower 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 lower guide pin bushings 6.
Described hammer stem 2 and upper guide bush 4 adopt the mode of Spielpassung to connect, described flange 3 and upper guide bush 4 adopt the mode of interference fit to connect, the material of described upper guide bush 4 is bronze or brass, described flange 3 and lower guide pin bushing 6 adopt the mode of Spielpassung to connect, and the material of described lower guide pin bushing 6 is bronze or 35 steel.
Because the radial outside of hammer stem 2 is provided with upper guide bush 4, upper guide bush 4 mainly plays guiding, prevent scratch hammer stem 2, when hammer stem 2 is done when longitudinally moving to limit position, platen 7 moves up lower guide pin bushing 6, because of lower guide pin bushing 6 and flange 3 employing Spielpassung, thereby so that high pressure asbestos 5 are compressed, flange 3 compresses high pressure asbestos 5, realized the effect of sealing, it is not enough to have controlled the engine power that causes because of cylinder 1 gas leakage, and oil consumption increases, fuel is bad at cylinder combustion, the phenomenons such as smoking of the exhaust or air-strainer gas blowby, reduce noise pollution, increased the working life of assorting mechanism.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
