Abstract
The utility model provides a car is bearing inner race for door window belongs to equipment field for the door window. It has solved prior art design reasonable scheduling problem inadequately. This car is bearing inner race for door window is equipped with and supplies the rolling annular raceway of roller, its characterized in that including circle body, circle body outer wall center circumference: circle body and annular raceway make by the aluminum material, annular raceway lateral wall on even cladding have the copper layer, on copper the layer outside evenly the cladding have wear - resistant ceramic coating. This car is bearing inner race for door window's advantage lies in: reasonable in design, simple structure, high just with low costs, the good heat dissipation of wearability.
Description
Technical field
The utility model belongs to vehicle window equipment technical field, especially relates to a kind of automotive window bearing inner race.
Background technique
Vehicle window in automobile component is the most used parts, and the opening and closing of vehicle window are all closely related with bearing, therefore proposes higher requirement to the portability of bearing, wear resistance, existing bearing is owing to have employed converted steel material, weight is large, easy to wear, and uses inconvenience.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, structure is simple, wear resistance is high automotive window bearing inner race.
For achieving the above object, the utility model have employed following technical proposal: automotive window bearing inner race of the present utility model, include circle body, circle body outer wall center is circumferentially with the ring raceway for roller rolls, it is characterized in that: described circle body and ring raceway are made up of aluminum material, described ring raceway outer side wall is uniformly coated with layers of copper, outside layers of copper, is uniformly coated with wear-resistant ceramic layer.Circle body and ring raceway are made up of aluminum material, alleviate weight, use light, and high-abrasive material is owing to adopting wear-resistant ceramic layer, and while maintenance high wear resistance, again reduce cost of production, layers of copper, due to good heat conductivity, improves heat dispersion.
Preferably, the thickness of described layers of copper is 1 to 2 millimeter.While guarantee thermal diffusivity, save cost of production.
Preferably, described wear-resistant ceramic layer thickness is 2 to 3 times of copper layer thickness.Wear-resistant ceramic layer, owing to directly contacting generation rolling friction with roller, is position the most easy to wear, therefore needs the thickness thicker than layers of copper, improves the circle working life outside bearing.
Preferably, the cross section of described ring raceway is circular arc.Be suitable for spherical roller to roll on ring raceway, not easily slip away ring raceway.
Preferably, the middle part of the wear-resistant ceramic layer on described ring raceway has annular oil storage tank, is communicated with bottom described annular oil storage tank with layers of copper.Annular oil storage tank contains lubricant oil, because it is communicated with layers of copper, accelerates the discharge function of heat due to inner ring and axle rotation generation, improves the working life of inner ring.
Compared with prior art, this automotive window advantage of bearing inner race is: reasonable in design, structure is simple, wear resistance is high and cost is low, thermal diffusivity is good.
Accompanying drawing explanation
Fig. 1 provides the structural representation of the utility model embodiment.
In figure, circle body 1, ring raceway 2, layers of copper 3, wear-resistant ceramic layer 4, annular oil storage tank 5.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in Figure 1, this automotive window bearing inner race, include circle body 1, circle body 1 outer wall center is circumferentially with the ring raceway 2 for roller rolls, it is characterized in that: circle body 1 and ring raceway 2 are made up of aluminum material, ring raceway 2 outer side wall is uniformly coated with layers of copper 3, wear-resistant ceramic layer 4 is uniformly coated with outside layers of copper 3, circle body 1 and ring raceway 2 are made up of aluminum material, alleviate weight, use light, high-abrasive material is owing to adopting wear-resistant ceramic layer 4, cost of production is again reduced while maintenance high wear resistance, layers of copper 3 is due to good heat conductivity, improve heat dispersion.
Particularly, the thickness of layers of copper 3 is here 1 to 2 millimeter, while guarantee thermal diffusivity, has saved cost of production; Here wear-resistant ceramic layer 4 thickness is 2 to 3 times of layers of copper 3 thickness, and wear-resistant ceramic layer 4, owing to directly contacting generation rolling friction with roller, is position the most easy to wear, therefore needs the thickness thicker than layers of copper 3, improves bearing inner race working life; The cross section of ring raceway 2 is here circular arc, and be suitable for spherical roller and roll on ring raceway 2, not easily slip away ring raceway 2.
Further, the middle part of the wear-resistant ceramic layer 4 on ring raceway 2 here has annular oil storage tank 5, be communicated with layers of copper 3 bottom annular oil storage tank 5, annular oil storage tank 5 contains lubricant oil, because it is communicated with layers of copper 3, accelerate because inner ring and axle rotate the discharge function of the heat produced, improve the working life of inner ring.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as circle body 1, ring raceway 2, layers of copper 3, wear-resistant ceramic layer 4, annular oil storage tank 5 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
