Description
Technical field
The utility model is related to gasket technical field more particularly to a kind of new automobile differential gear gaskets.
Background technology
The planetary gear and semiaxis that differential mechanism generally comprises differential casing, is arranged in differential carrier body and is engaged with each other
Gear (being referred to as " differential gear ") and the planetary cross axle of assembly.In the course of work of Work machine drive axle
In, differential gear can bear very big load and be rotated about axis, and generally be wanted between differential casing and differential gear thus
Cog spacers are installed to improve contact stress, prevent inordinate wear, ensure differential gear normal engagement for a long time, to ensure
Drive axle is worked normally for a long time without failing.
There is serious quality accident due to abrasion in use in differential gasket currently on the market, main to show
It is worn in differential gasket, causes cross axle sintering, differential gear to beat tooth failure, to cause differential mechanism to damage, according to difference
The working environment of fast device gasket, gasket surface is smooth, is not easy to form oil film or oil film is easily destroyed, and loses oil film protection, causes
Gasket serious wear.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of high lubricating effect, wear-resisting property are high, and with anti-rotation knot
The new automobile differential gear gasket of structure.
A kind of new automobile differential gear gasket comprising shim body, wear-resistant coating and protrusion, the shim body
For annulus sheet, including first surface and second surface, the first surface is equipped with the symmetrical oil groove of several groups and several
Oil storage nest, and be coated with the wear-resistant coating of 20-200um, the wear-resistant coating are molybdenum disulfide wear-resistant coating, by molybdenum disulfide,
Epoxy resin, phenolic resin, cyclohexanone, acetone composition；Several protrusions are arranged on the second surface.
Further, the shim body uses PA1010 alloy materials.
Further, the oil groove is 2-8, and the depth of the oil groove is 2.0 ± 0.1mm, width 3-6mm.
Further, the oil storage nest is hemispherical either circle or ellipse, and depth is 1.5 ± 0.1mm.
Further, the protrusion is 2-8, and shape is square boss outstanding.
Compared with the prior art, what the utility model reached has the beneficial effect that：（1）Differential gear gasket material is changed to
PA1010 alloy materials, and using the structure design of oil groove and oil storage nest, substantially increase lubricant effect.（2）In gasket surface
The molybdenum disulfide wear-resistant coating with good self-lubricating effect is coated, the wear-resisting property of gasket is substantially increased, extends the service life.
（3）It is designed using raised anti-rotation, effectively gasket can be prevented to trackslip, gasket is avoided to be rotated with axle shaft gear, prevented pad
Abrasion of the piece to differential casing improves service life.
Description of the drawings
Fig. 1 is the positive structure diagram of the new automobile differential gear gasket of the utility model embodiment.
Fig. 2 is the backsight structural representation of the new automobile differential gear gasket of the utility model embodiment.
Fig. 3 is the A-A of Fig. 1 to sectional view.
Fig. 4 is the B-B of Fig. 1 to sectional view.
Specific implementation mode
The utility model is described in detail below with reference to specific embodiments and the drawings.
- 4 are please referred to Fig.1, shows a kind of embodiment of the utility model, a kind of new automobile differential gear gasket
10 comprising shim body 1, wear-resistant coating 2 and protrusion 3, the shim body 1 are annulus sheet, including 11 He of first surface
Second surface 12, the first surface 11 is equipped with the symmetrical oil groove 13 of several groups and several oil storage nests 14, and is coated with 20-
The wear-resistant coating 2 of 200um, the wear-resistant coating 2 is molybdenum disulfide wear-resistant coating, by molybdenum disulfide, epoxy resin, phenolic aldehyde tree
Fat, cyclohexanone, acetone composition carry significantly in molybdenum disulfide wear-resistant coating of the gasket surface coating with good self-lubricating effect
The high wear-resisting property of gasket, extends the service life；It is arranged with several protrusions 3 on the second surface 12, can effectively prevent
Gasket trackslips, and gasket is avoided to be rotated with axle shaft gear, has prevented abrasion of the gasket to differential casing, improves and uses the longevity
Life.
Further, as the preferred of the present embodiment, the shim body 1 uses PA1010 alloy materials.
Further, the oil groove 13 is 2-8, and as the preferred of the present embodiment, the oil groove 13 is 4, the oil
The depth of slot 13 is 2.0 ± 0.1mm, width 3-6mm.The increasing of depth and width is conducive to increase oil mass, increases lubrication
Effect.
Further, as the preferred of the present embodiment, the oil storage nest 14 is hemispherical either circle or ellipse, deep
Degree is 1.5 ± 0.1mm.The increasing of 14 depth of oil storage nest is conducive to the oil storage for increasing gasket surface, increases lubricant effect.
Further, described raised 3 be 2-8, and shape is square boss outstanding, as the preferred of the present embodiment, institute
It is 4 to state protrusion, effectively gasket can be prevented to trackslip.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
Novel interest field, therefore equivalent variations made according to the claim of the utility model still belong to what the utility model was covered
Range.
