Abstract
The utility model relates to a carbon base wear resistance synchronous gear ring, which is characterized by comprising an annular substrate, wherein spline teeth are arranged on the outer circumference edge of the substrate, an inner cone hole is arranged on the substrate, a carbon base wear resistance layer is arranged on the inner conical hole surface, and the carbon base wear resistance layer consists of a wear resistance layer and a support layer. The carbon base wear resistance synchronous gear ring has the advantages that the carbon base wear resistance layer is bonded in the inner cone hole of the synchronous gear ring, the wear resistance performance and the high temperature resistance performance are improved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of synchronizer of automobile gearbox, especially relates to the wear-resisting synchronizing tooth ring of a kind of carbon back.
Background technique
The ring gear of synchronizer is the critical component of gear shift operation in the automotive transmission.The friction torque of utilizing the conical surface to produce makes run-in synchronism between 2 gearshift components and parts, thereby realizes gearshift.Defectives such as the domestic copper ring commonly used or the material of steel loop sprayed molybdenum facts have proved that the friction factor of these 2 kinds of materials is lower, and the torque ratio of transmission is less, and resistance to high temperature is relatively poor, and working life is short.
The model utility content
The applicant has carried out research and has improved to above-mentioned problem, provides a kind of carbon back wear-resisting synchronizing tooth ring, has high friction coefficient, improves wear-resisting property and resistance to high temperature, increases the service life.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
The wear-resisting synchronizing tooth ring of a kind of carbon back comprises the matrix of ring, and the outer annulus edge of said matrix is provided with spline tooth, and said matrix is provided with internal taper hole, and said internal taper hole surface is provided with the carbon back wearing layer, and the carbon back wearing layer is made up of the wearing layer and the supporting layer on surface.
The technique effect of the utility model is:
The wear-resisting synchronizing tooth ring of the disclosed a kind of carbon back of the utility model, bonding carbon back wearing layer improves wear-resisting property and resistance to high temperature in the internal taper hole of synchronizing tooth ring, increases the service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
As shown in Figure 1, the utility model comprises the matrix 1 of ring, and the outer annulus edge of matrix 1 is provided with spline tooth 3, and matrix 1 is provided with internal taper hole 2, and the surface of internal taper hole 2 is provided with carbon back wearing layer 4, and carbon back wearing layer 4 is made up of the wearing layer and the supporting layer on surface.Wherein, the mass percent of the component of wearing layer and each component is: graphite fiber 10 ~ 25%, acrylonitrile pulp 5 ~ 10%, velveteen pulp 15 ~ 20%, nanometer phenolic resin 18 ~ 25%, graphite 3 ~ 8%, iron oxide red 3 ~ 8%, aluminium oxide 1 ~ 5%, calcium carbonate 5 ~ 15%, carboxylic acrylonitrile butadiene rubber latex 3 ~ 6%, aluminum sulphate 1 ~ 2%, sodium hydroxide 0.7 ~ 1.4%, polyacrylic amide 0.01 ~ 0.03%; The component of supporting layer and the mass percent of each component are: velveteen pulp 20 ~ 30%, glass fibre 25 ~ 40%, calcium carbonate 0 ~ 30%, aluminum sulphate 1 ~ 2%, polyacrylic amide 0.01 ~ 0.03%, nanometer phenolic resin 15 ~ 25%, textile industry leftover pieces 0 ~ 30%.
The making step of carbon back wearing layer 4 is following:
(1) said wearing layer and supporting layer are mixed by its set of dispense ratio respectively, and add the water of quality respectively, form wearing layer mixed solution and supporting layer mixed solution for 1 ~ 5 times in its mixture;
(2) wearing layer mixed solution and supporting layer mixed solution get up to the silk screen laminated through different pipelines while curtain coatings, and wherein wearing layer is on the upper strata, and supporting layer is in lower floor;
(3) silk screen is in vibrational state, makes the fiber in the wearing layer pass supporting layer, and through the roller extruding wearing layer firmly is connected with supporting layer;
(4) wearing layer is connected back formation the utility model carbon back high-abrasive material with supporting layer, and wherein residual moisture is sloughed through extruding and oven dry;
(5) with carbon back high-abrasive material cut into and treat the to bond internal taper hole face consistent size of ring gear;
(6) the internal taper hole face with the alligatoring ring matrix that completes cleans;
(7) be coated with modification phenolic resin in carbon back high-abrasive material support layer surface;
(8) its horizontal positioned is waited for curing in mould, formation carbon back wearing layer 4 after the carbon back high-abrasive material bonding that the internal taper hole of matrix 1 is surperficial with gluing has been crossed;
(9) solidify to accomplish after, utilize the Vehicle Processing chamfering, go out the impurity such as glue that overflow, cleaning synchronizing tooth ring surface.
