Description
Technical field
This utility model belongs to technical field of mechanical transmission, is specifically related to a kind of Combined type wear-resisting gear.
Background technology
Gear is the mutually engageable machine components having tooth, applies extremely wide in whole mechanical field, especially mechanical transmission fields, is the important foundation part of plant equipment, and the drive disk assembly of overwhelming majority plant equipment is all gear drive.At present, gear is mainly prepared from by metal material, as made with 40Cr or 45Cr steel, the composition according to raw material metal is needed in heat treatment process, grain size, purity etc. make normalizing or modifier treatment, to improve gear end product quality, and plover tooth process need to be carried out, remove flash removed, and prevent knock damage, reduce tooth-face roughness, can effectively reduce the gear noise that thus reason causes in transmission process, as can be seen here, gear is prepared with metal material, complex technical process, condition controls strict, and gear is after long-time use, easily cause abrasion, affect the normal use of equipment.
Application number 201510749250.X discloses the nanometer diamond alkene of the layer structure of a kind of novel controllable type, for lamellar mono-crystalline structures, is sp between the carbon atom of same lamella3Orbital hybridization carbon bond connects, and is sp between carbon atom between layers2Orbital hybridization carbon bond connects, and has the advantages that hardness is high and wear-resisting.
Utility model content
This utility model purpose is to provide a kind of Combined type wear-resisting gear.
Based on object above, this utility model takes techniques below scheme:
A kind of Combined type wear-resisting gear, including gear substrate layer be connected to the outer peripheral denticle of gear substrate layer, described denticle is made up of nanometer diamond alkene sintering.
Described denticle inward flange is provided with several bayonet lock, and gear substrate layer outward flange is provided with the draw-in groove corresponding with bayonet lock, and denticle is connected with draw-in groove by bayonet lock.
Described bayonet lock and draw-in groove all have 8, are evenly distributed on denticle and gear substrate layer.
Described denticle is made up of the nanometer diamond alkene of tri-kinds of granularities of 10-20nm, 40-50nm and 200-250nm, granularity be the mass ratio between the nanometer diamond alkene of 10-20nm, 40-50nm, 200-250nm be (10-20): (30-40): (50-60).
Described gear substrate layer is made up of nano zircite calcining.
Compared with prior art, this utility model has the advantage that
1, denticle of the present utility model is made up of nanometer diamond alkene sintering, improves hardness and the anti-wear performance of denticle, extends the service life of denticle, and in use, along with the prolongation of the time of use, denticle surface has very thin one layer and is converted into graphite, it is possible to increase the greasy property of transmission.
2, denticle is connected with the draw-in groove on gear substrate layer by bayonet lock, after denticle has abrasion, is drawn off by denticle from draw-in groove, reinstalls new denticle, it is not necessary to changes gear substrate layer, has saved production cost, economical and practical.
3, gear substrate layer is made up of nano zircite calcining, has the advantage that hardness is high, wear-resisting, and compared with metal, cost is relatively low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of Combined type wear-resisting gear, as shown in Figure 1, including gear substrate layer 1 be connected to the outer peripheral denticle of gear substrate layer 12, described denticle 2 is made up of nanometer diamond alkene sintering, denticle 2 is by 10-20nm, the nanometer diamond alkene of tri-kinds of granularities of 40-50nm and 200-250nm is made, granularity is 10-20nm, 40-50nm, mass ratio between the nanometer diamond alkene of 200-250nm is 20:30:50, denticle 2 inward flange is provided with 8 bayonet locks 3 being evenly distributed, 8 draw-in grooves corresponding with 8 bayonet locks 3 it are provided with on gear substrate layer 1 outward flange, denticle 2 is connected with draw-in groove by bayonet lock 3.
Denticle 2 is formed by nanometer diamond alkene mixed sintering, and bonding agent used is waterglass, and bonding agent weight is 6%-8% with the weight ratio of nanometer diamond alkene, through high-temperature baking, uses notch cuttype baking process to carry out, and the highest baking temperature is less than 280 DEG C.Denticle 2 of the present utility model is made up of nanometer diamond alkene sintering, improve hardness and the anti-wear performance of denticle 2, extend the service life of denticle 2, and in use, prolongation along with the time of use, denticle 2 surface has very thin one layer and is converted into graphite, it is possible to increase the greasy property of transmission.
During use, directly denticle 2 is installed, after using a period of time, after denticle 2 has abrasion, denticle 2 is drawn off from draw-in groove, reinstall new denticle, it is not necessary to change gear substrate layer, saved production cost, economical and practical.
