Abstract
The invention discloses a standing bolt for a fixed rail of a timing chain, which comprises a bolt head and screw rods, wherein the screw rods are divided into a first screw rod, a second screw rod and a third screw rod; an annular groove is formed on the first screw rod; a first step is arranged between the first screw rod and the second screw rod; the diameter of the first screw rod is greater than that of the second screw rod; a second step is arranged between the second screw rod and the third screw rod; and full threads are formed on the third screw rod. The standing bolt has high sealing effect, and can clamp the fixed rail on an engine easily.
Description
Technical field
The present invention relates to a kind of fixing bolt, especially relate to timing chain orbit determination fixing bolt on the motor.
Background technique
Timing cover is the important constituent element of motor, plays effects such as sound insulation and noise reduction, sealing.At present in order better to improve the assembly technology of timing cover, and guarantee its sealing, engine timing cover and cylinder body, cylinder cap are integrated is cast as one, timing cover no longer is an independently part, this kind arrangement has reduced the assembling of timing cover, and reduced the use of cover cap bolt, and simplified assembly technology greatly, sealing effect is also relatively good.But timing cover for this kind arrangement, the orbit determination of timing chain adopts common bolt to be difficult to fix, and motor is when high speed operation, because orbit determination is fixing not tight, chain can drive orbit determination and move on orbit determination fixing bolt axial direction, makes chain not at grade, there is the hidden danger of jumping tooth, influence the normal operation of motor, the sealing between bolt and timing cover simultaneously can't guarantee, occurs the leakage of oil situation sometimes.
Summary of the invention
The purpose of this invention is to provide a kind of timing chain orbit determination fixing bolt, engine timing cover and cylinder body, cylinder cap is integrated when being cast as one, solve existing bolt be difficult to orbit determination fastening, the problem of bolt and timing cover sealing effect difference.
The technical solution adopted for the present invention to solve the technical problems is: a kind of timing chain orbit determination fixing bolt, and it comprises bolt head and screw rod; Described screw rod is divided into first screw rod and second screw rod and the 3rd screw rod, offer the groove of annular on described first screw rod, be provided with first step between described first screw rod and second screw rod, the diameter of described first screw rod is greater than the diameter of second screw rod, be provided with second step between described second screw rod and the 3rd screw rod, attacked Full Thread FT on described the 3rd screw rod.
Further, described bolt head is the structure by screw rod side band gasket shape.The described screw head outside is outer-hexagonal shape.The diameter of described second screw rod is greater than the diameter of the 3rd screw rod.
Do not produce stress when preventing that bolt from tightening and concentrate, the pad distance of the groove on described first screw rod on bolt head is at least 3mm.
Beneficial effect of the present invention: owing to offer the groove of annular on described first screw rod, be provided with first step between described first screw rod and second screw rod, the diameter of described first screw rod is greater than the diameter of second screw rod.In described groove seal ring is housed, seal ring and timing cover hole closely are adjacent to, and prevent leakage of oil, good airproof performance.Described first step is fixedly clamped orbit determination on motor, and chain is guaranteed on same horizontal plane, guarantees that motor normally moves.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is an assembling condition partial sectional view of the present invention.
Fig. 2 is the organigram of timing chain orbit determination fixing bolt of the present invention.
Among the figure: 1. motor, 2. timing cover, 3. orbit determination, 4. bolt, 5. seal ring, 6. bolt head, 7. pad, 8. groove, 9. first screw rod, 10. first step, 11. second screw rods, 12. second steps, 13. the 3rd screw rods.
Embodiment
Assembly method of the present invention is, earlier orbit determination 3 is placed on the mounting point between timing cover 2 and the motor 1, again bolt 4 is passed the bolt hole of timing cover and orbit determination, the 3rd screw rod 13 that has Full Thread FT foremost is screwed on the bolt hole of motor 1, and first screw rod 9 cooperates with bolt hole on the timing cover 2, and the seal rings 5 in the groove 8 are tight with the sealing of timing cover holes.Second bolt 11 cooperates with bolt hole on the orbit determination 3, is used to support orbit determination, and described first step 10 is fixedly clamped orbit determination on motor.When the present invention had prevented the chain high speed operation, orbit determination was moved to the bolt axial direction, made chain slippage phenomenon not occur on same horizontal plane.Guaranteed that motor normally moves, and good airproof performance, leakage of oil prevented.
