Abstract
The utility model discloses a shaft sealing structure for motorcycle engine, comprising a cover plate, a shaft through the cover plate, a groove for sealing ring mounted around the shaft hole on the cover plate and a press plate for compressing the sealing ring, characterized in that the groove for sealing ring mounting is conical, the included angle between the groove wall and the shaft being acute; the sealing ring is squeezed among the groove wall, the shaft and the press plate. The shaft sealing structure has simple processing and excellent sealing performance.
Description
Technical field
The utility model relates to a kind of sealing configuration of motorcycle engine, is the sealing configuration between axle and the cover plate specifically.
Background technique
Often have sealing configuration shown in Figure 1 on motorcycle engine, an axle 1 will pass through for example crankcase cover of cover plate 4, stretches out airtight chamber, will seal axle 1.Its sealing configuration is to open an annular counterbore 5 around the axis hole of cover plate 4, utilizes pressing plate 2 to compress and is contained in the interior seal ring 3 of counterbore, seals.As shown in Figure 2, the effect of the vertical F of seal ring compression plate generation in this case can produce better seal to counterbore 5 bottom surfaces, but the surface of contact of seal ring 3 and axle 1, because the elastic deformation force who has only seal ring 3 to produce, sealing effect is bad, leakage phenomenon often occurs.
The model utility content
The purpose of this utility model just is to provide a kind of axle sealing structure of motorcycle engine, and this sealing configuration has improved the sealing effect of axle by the effect of the component of pressing plate generation.
A kind of axle sealing structure of motorcycle engine, comprise cover plate, pass the axle of cover plate, the groove that seal ring is installed is arranged around the cover plate upper shaft hole, and the pressing plate that compresses seal ring, it is characterized in that: the groove of described installation seal ring is a cone tank, cell wall acutangulates angle with axle, and described seal ring is compressed between cell wall, axle and the pressing plate.
Angle between described cell wall and the axle, more satisfactory is 30 °～45 °, optimum is 45 °.
The axle sealing structure of this motorcycle engine of the present utility model, place seal ring owing to adopted cone tank, make seal ring be pressed between the cell wall on pressing plate, axial wall and the cover plate, utilize the component of pressing plate function power to make between seal ring and the cover plate and between the axle and all have the better seal effect, improve axle envelope quality, reduced the generation of leaking; And, process convenient with respect to counterbore.
Description of drawings
Fig. 1 is the axle sealing structure schematic representation of existing motorcycle engine.
Fig. 2 is the seal ring free-body diagram of motorcycle engine axle sealing structure shown in Figure 1.
Fig. 3 is the axle sealing structure schematic representation of motorcycle engine of the present utility model.
Fig. 4 is the seal ring free-body diagram of motorcycle engine axle sealing structure shown in Figure 3.
Embodiment
Be described further below in conjunction with the axle sealing structure of the drawings and specific embodiments motorcycle engine of the present utility model.
As shown in Figure 3, axle 1 axis hole that passes on the cover plate 4 of motorcycle engine, the groove 5 that seal ring 3 is installed around cover plate 4 upper shaft holes is cone tank, and cell wall acutangulates angle with axle 1, and seal ring 3 is compressed between cell wall, axle 3 and the pressing plate 2.The stressing conditions of seal ring as shown in Figure 4, the directed force F of pressing plate makes and produces component F1 between seal ring and the cell wall, and generation component F2 between while and the axle, the effect of component F1 makes and contacts good between the cell wall on seal ring 3 and the cover plate 4 and form good sealing, and component F2 can improve the sealing effect between the seal ring 3 and spool 1.The taper cell wall of groove 5 and the comparatively ideal angle of axle between 1 are 30 °～45 °, and optimum value is 45 °, so that two component F1 and F2 are reasonable, improve overall shaft sealing effect, reduce leakage.Groove 5 directly in the axis hole on cover plate 4 chamfering form, so this structure processing is simple, need not to use combined cutting tool processing counterbore.
The utility model processing is simple, sealing effect is good, practical, respond well in actual applications.
Claims (3)
1, a kind of axle sealing structure of motorcycle engine, comprise cover plate, pass the axle of cover plate, the groove that seal ring is installed is arranged around the cover plate upper shaft hole, and the pressing plate that compresses seal ring, it is characterized in that: the groove of described installation seal ring is a cone tank, cell wall acutangulates angle with axle, and described seal ring is compressed between cell wall, axle and the pressing plate.
2, the axle sealing structure of motorcycle engine as claimed in claim 1 is characterized in that: the angle between described cell wall and the axle is 30 °～45 °.
