Abstract
The utility model relates to a kind of manual transmission box sealing face structures, including cabinet before speed changer and its speed changer rear box being correspondingly connected with, the face of cabinet and the corresponding contact of speed changer rear box is respectively sealing surface before the speed changer, it is characterized in that: being covered with micro- striped of intersection on the sealing surface, reticulate pattern structure is constituted, is coated with sealant on the region of reticulate pattern structure.The utility model can make the sealing surface of mission case in gluing, tighten and retain suitable sealant after bolt, reduce oil leak risk, thus lift-off seal effect.
Description
Technical field
The utility model relates to speed changers, and in particular to a kind of manual transmission box sealing face structure.
Background technique
Mission case is usually made of preceding cabinet and rear box.The preceding cabinet and rear box of existing manual transmission it
Between sealing generally use the mode that sealant adds bolt to tighten, box sealing face is generally planar, roughness Ra 0.8-3.2,
Flatness 0.06~0.10.It is " a kind of that phosphorus is carried out to transformer-cabinet sealing surface using phosphatization cream as disclosed in CN 101440469
Change the method for processing ".For another example disclosed in CN205190485U " a kind of sealing effect is preferably used for the locking sealing on speed changer
Bolt arrangement ", bolt body include the spiral shell that nuts and diameter are less than the nuts and are extended downwardly by the nuts bottom
Tightening latch, shank of bolt periphery are covered with screw thread, and mission case is equipped with threaded hole, the screw thread and speed changer of the shank of bolt of bolt body
Threaded hole on cabinet is tightly connected and protrudes into transmission case body: the bottom surface of the nuts of bolt body be equipped at least one to
Lower protrusion annular projection (, the hardness of bolt body is greater than the hardness of mission case, the bottom surface of the nuts of bolt body
The upper surface palette of downwardly projecting annular projection and mission case.But all it is not involved with improvement transmission case
The problem of structure of body sealing surface.
Referring to figure 1, figure 2 and figure 3, the sealing means of existing mission case are close to apply in the sealing area a of preceding cabinet 1
Sealing 4, then preceding cabinet 1 and rear box 2 are connected by bolt 3.In this way, cabinet gluing, tighten mould assembling bolt after, it is close
Sealing is pressed against the two sides in mould assembling face, and the remaining sealant of sealing area seldom or almost without.If the seal area of cabinet
It is overproof that flatness occurs slightly knocking against or process in domain, may occur in use sealing surface seep, oil leak the case where.Cause
This, needs the sealing surface structure to existing mission case to improve.
Summary of the invention
The purpose of the utility model is to provide a kind of manual transmission box sealing face structures, can make mission case
Sealing surface in gluing, tighten and retain suitable sealant after bolt, reduce oil leak risk, thus lift-off seal effect.
A kind of manual transmission box sealing face described in the utility model structure, including cabinet and its correspondence before speed changer
The speed changer rear box of connection, the face of cabinet and the corresponding contact of speed changer rear box is respectively sealing surface before the speed changer,
It is characterized in: is covered with micro- striped of intersection on the sealing surface, constitutes reticulate pattern structure, be coated on the region of reticulate pattern structure
Sealant.
Further, the roughness of the reticulate pattern structural region is Rz10~20.
Preferably: be micro- striped in 5.0mm reticulate pattern structural region in width being 6~10.
The utility model has the beneficial effects that
Due to being covered with the micro- of intersection respectively on the cabinet before speed changer and the sealing surface of the corresponding contact of speed changer rear box
Striped constitutes reticulate pattern structural region, after cabinet and speed changer rear box are correspondingly connected with connection before speed changer, reticulate pattern structure
Region retains part sealant, has minimized oil leak risk；After-sales service cost is thereby reduced, it is satisfied to promote user
Degree；Promote brand recognition.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of cabinet and rear box before speed changer；
Fig. 2 is the schematic diagram of the non-gluing of mission case；
Fig. 3 is the schematic diagram after mission case gluing；
Fig. 4 is the structural schematic diagram of the utility model；
Fig. 5 is the portion the A enlarged drawing of Fig. 4；
Fig. 6 is the section amplification figure of sealing surface.
In figure: 1-preceding cabinet, 2-rear box, 3-connection bolts, 4-sealants；
10-sealing surfaces, 11-micro- stripeds, 12-reticulate pattern structures.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Referring to fig. 4, a kind of manual transmission box sealing face structure described in Fig. 5 and Fig. 6, including before speed changer cabinet and
Its speed changer rear box being correspondingly connected with, the face of cabinet and the corresponding contact of speed changer rear box is respectively to seal before the speed changer
Face 10 constitutes reticulate pattern structure 12, in reticulate pattern knot it is characterized in that: being covered with micro- striped 11 of intersection on the sealing surface 10
Sealant is coated on the region of structure 12.After cabinet and speed changer rear box are correspondingly connected with connection before speed changer, reticulate pattern structure
Region retains part sealant, to achieve the effect that lift-off seal performance.
The roughness in 12 region of reticulate pattern structure is Rz10~20.
It is micro- striped 11 in 12 region of 5.0mm reticulate pattern structure in width is 6~10.
By the adjustment to transmission case body processing technology, tiny reticulate pattern is formed on the box sealing face for being originally used for plane
Shape, after gluing, mould assembling assembly, reticulate pattern structural region can retain part sealant, achieve the effect that lift-off seal performance.
