Abstract
The utility model discloses one and repair careless car car wheel structure, comprise tire, wheel shaft, clutch shaft bearing, the second bearing, jam nut and iron axle sleeve; Be provided with bearing step in its tire endoporus, the both sides of this endoporus centre bearer step are located at by clutch shaft bearing and the second bearing, are provided with iron axle sleeve between the outer shroud of clutch shaft bearing and the second bearing; Wheel shaft is successively through clutch shaft bearing, iron axle sleeve, the second bearing, and its shaft shoulder is stuck in clutch shaft bearing outer end, and second step is provided with and can screws to obtain jam nut to the inside along second step; The length of iron axle sleeve is equal to or greater than the length of bearing step.In this programme when wheel is locked in wheel shaft, by iron axle sleeve but not wheel bears the axially loaded that jam nut brings, make wheel can smooth running; Ensure that the distance between bearing does not change simultaneously, ensure that wheel axial dimension is stablized, eliminate in metal bearing wedging plastic wheel bearing step hidden danger axial width being diminished make wheel axial motion, improve reliability and service life.
Description
Technical field
The utility model relates to one and repaiies careless car, is specifically related to one and repaiies careless car car wheel structure.
Background technology
The existing wheel repairing the standard rolling bearing that careless car uses, wheel bearing is spacing by the step of plastic wheel.When wheel fit on repaiies careless car complete machine, the axial force that after the wheel of plastic product bears wheel locking, jam nut brings, causes wheel to occur clamping stagnation after axially loaded, the bad phenomenon such as to seize up.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides one to repair careless car car wheel structure, occurs clamping stagnation, problem to seize up to solve existing wheel after axially loaded.
Technical scheme: for solving the problems of the technologies described above, the one that the utility model provides repaiies careless car car wheel structure, comprises tire, wheel shaft, clutch shaft bearing, the second bearing, jam nut and iron axle sleeve;
The shaft core position of described tire is provided with endoporus, bearing step is provided with in this endoporus, the both sides of this endoporus centre bearer step are located at by described clutch shaft bearing and the second bearing, and with tire interference fit, be provided with the iron axle sleeve being looped around wheel shaft outside between the outer shroud of described clutch shaft bearing and the outer shroud of the second bearing;
Described wheel shaft is made up of the shaft shoulder, first step and second step successively, and this wheel shaft is successively through clutch shaft bearing, iron axle sleeve, the second bearing, and its shaft shoulder is stuck in clutch shaft bearing outer end, and second step is provided with and can screws to obtain jam nut to the inside along second step;
The length of described iron axle sleeve is equal to or greater than the length of bearing step.
Preferably, the maximum outside diameter of described iron axle sleeve equals the aperture of tire endoporus centre bearer step.
Preferably, the shaft shoulder of described wheel shaft is circular or polygon.
Preferably, described iron axle sleeve and bearing step interference fit.In this scheme, the interference fit of iron axle sleeve and bearing step can make the iron axle sleeve not vibration when Xiu Cao garage is walked.
Preferred as another kind, the inwall of described tire endoporus centre bearer step is provided with some projections, and described iron axle sleeve is stuck in some projections and is limited between clutch shaft bearing and the second bearing.Preferably, described some projections are reinforced rib.In this scheme, this some projection can play to be stablized iron axle sleeve when Xiu Cao garage is walked and makes it that effect of vibration not occur, and more easily assembles relative to a upper scheme.
Beneficial effect: what the utility model provided repaiies careless car car wheel structure, iron axle sleeve is increased between bearing, iron sleeve length equals or slightly larger than the distance of bearing step, when wheel is locked in wheel shaft, by iron axle sleeve but not wheel body bears the axially loaded that jam nut brings, make wheel can smooth running; Simultaneously because the intensity of iron axle sleeve is larger, ensure that the distance between bearing does not change, also ensure that the axial dimension of wheel is stablized, eliminate in metal bearing wedging plastic wheel bearing step hidden danger axial width being diminished make wheel axial motion, improve the operation comfort repairing careless car, improve reliability and the service life of wheel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model repaiies the structural representation of careless car car wheel structure as shown in Figure 1, is further described the utility model below in conjunction with drawings and Examples.
Embodiment 1:
As shown in Figure 1, embodiment 1 repair careless car car wheel structure, comprise tire 1, wheel shaft 2, clutch shaft bearing 3, second bearing 4, jam nut 5 and iron axle sleeve 6;
The shaft core position of described tire 1 is provided with endoporus, bearing step 7 is provided with in this endoporus, the both sides of this endoporus centre bearer step 7 are located at by described clutch shaft bearing 3 and the second bearing 4, and with tire 1 interference fit, be provided with the iron axle sleeve being looped around wheel shaft 2 outside between the outer shroud of described clutch shaft bearing 3 and the outer shroud of the second bearing 4;
Described wheel shaft 2 is made up of the shaft shoulder, first step and second step successively, this wheel shaft 2 is successively through clutch shaft bearing 3, iron axle sleeve 6, second bearing 4, its shaft shoulder is stuck in clutch shaft bearing 3 outer end, and second step is provided with and can screws to obtain jam nut 5 to the inside along second step;
The length of described iron axle sleeve 6 is equal to or greater than the length of bearing step 7.
Described iron axle sleeve 6 and bearing step 7 interference fit.
The shaft shoulder of described wheel shaft 2 is circular or polygon.
Embodiment 2: substantially identical with embodiment 1 structure, something in common is not repeated, and difference is:
The maximum outside diameter of described iron axle sleeve 6 equals the aperture of tire 1 endoporus centre bearer step 7.
Embodiment 3: substantially identical with embodiment 1 structure, something in common is not repeated, and difference is:
The inwall of described tire 1 endoporus centre bearer step 7 is provided with some projections, and described iron axle sleeve 6 is stuck in some projections and is limited between clutch shaft bearing 3 and the second bearing 4.Described some projections are reinforced rib.
For embodiment 1, the principle of work of careless car car wheel structure that what the utility model provided repair is: between clutch shaft bearing 3, second bearing 4, increase iron axle sleeve 6, iron axle sleeve 6 length equals or slightly larger than the distance of bearing step 7, when wheel is locked in wheel shaft 2, by iron axle sleeve 6 but not wheel body bears the axially loaded that jam nut 5 brings, wheel can smooth rotation be run; Simultaneously because the intensity of iron axle sleeve 6 is larger, ensure that the distance between clutch shaft bearing 3, second bearing 4 does not change, also ensure that the axial dimension of wheel is stablized, eliminate in metal bearing wedging plastic wheel bearing step 7 hidden danger axial width being diminished make wheel axial motion, improve the operation comfort repairing careless car, improve reliability and the service life of wheel.
Above implementation column does not form restriction to the utility model, and relevant staff is in the scope not departing from the utility model technological thought, and the various change carried out and amendment, all drop in protection domain of the present utility model.
