Abstract
The utility model relates to a wheel shaft group used on a railway vehicle. Wheel shafts used in the wheel shaft group form a cylindrical shape; the outer surfaces of the wheel shafts are provided with shaft sleeves matched with the outer diameters of the wheel shafts; bearings are fixed on the shaft sleeves. The wheel shaft group with the structure can fundamentally solve the problem of burning the shafts, provide convenience to inspection or maintenance and prolong the service lives of the bearings in addition.
Description
This practical new life relates to a kind of axle set that is specifically designed on the rolling stock.
Rolling stock especially metallurgy industry the axle set on the special-purpose railroad vehicle, a kind of version is to adopt the wheel shaft that has certain taper, be inlaid with the axle sleeve that is complementary with its tapering on this wheel shaft, and in the axle sleeve outside bearing be installed, tapered sleeve works to connect wedging in the centre.Because axle set is centre part, almost bears the total weight of car body and bearing goods and be to be in the state of relatively rotating under to work.And axle sleeve in the axle set of said structure and wheel shaft are conical surface wedgings, the area of contact that this assembling cooperates is difficult to reach more than 50%, sometimes be loop contacts substantially, so, the wheel shaft weight of whole locomotive body in the course of the work all focuses on the contact surface with the fraction of axle sleeve, easily make the wheel shaft heating, even serious accidents such as axle are fired in appearance; Secondly, what above-mentioned bearing adopted is the spherical roller tilting bearing, though it is strong that this class bearing has a load-carrying capacity, advantages such as the aligning scope is big, but because the aligning model is big more, the dustproof effect of axle box is just poor more, and dust can cause bearing to pollute, so this point also is to cause the Another reason of hot box accident; In addition, no matter be wheel shaft or axle sleeve, because they all have tapering, so, processing technology, working accuracy, assembling, maintenance even insulation etc. are required very strictness, this has not only improved cost, but also has increased the difficulty of processing and maintenance.
In the prior art, the axle set of another kind of structure is to adopt on d-axis directly pressing bearing mode, and it is simple in structure that let it be to the greatest extent, but since bearing directly contact with wheel shaft, so it not only easily makes the wheel shaft damage, and also suitable complexity of maintenance process and technology.
Task of the present utility model provides a kind of axle set that is used on the rolling stock, and it can fundamentally solve combustion axle problem by the simple modifications to its shape, and can be convenient to maintenance.
For finishing above-mentioned task, the wheel shaft that adopts in the axle set described in the utility model is cylindrical, and the wheel shaft outside face is equipped with the axle sleeve that is complementary with its external diameter, and its bearing fixing is on axle sleeve.
Be free-running fit between described axle sleeve and the wheel shaft, and stop pin is installed betwixt.Described wheel shaft end is provided with and is used for the cannelure of installation shaft to the location collar, and the anti-slow gland by bolt is installed on wheel axle end surface.
Because the utility model adopts d-axis to add the structure of straight cover, it can make the contact surface between wheel shaft and the axle sleeve almost reach 100%, so the axle set of this kind structure has fundamentally solved combustion axle problem; Simultaneously be gapped between wheel shaft and the axle sleeve and fix,,, but also can save the cost of overhaul not only for maintenance or safeguard convenience is provided so axle sleeve takes off from wheel shaft easily by stop pin; In addition, this kind structure also can prolong the service life of bearing.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing 1 is the utility model cross-sectional view.
Referring to Fig. 1, it comprises an axle box 1, and this axle box end is equipped with and its outer protecgulum 2 that is complementary by bolt.Be provided with columniform wheel shaft 8 in the axle box 1, at its outside face the axle sleeve 4 of straight shape be installed, the outside of this axle sleeve is equipped with circular cone roll-type bearing 3, and is fixed on the axle sleeve 4 by top cover 6, collar 7 and anti-slow gland 5.Be free-running fit between described axle sleeve 4 and the wheel shaft 8, and the stop pin 9 that is made of flat key is installed betwixt.
Claims (3)
1. rolling stock wheel shaft group, it is characterized in that: the wheel shaft that adopts in this axle set is cylindrical, and the wheel shaft outside face is equipped with the axle sleeve that is complementary with its external diameter, and its bearing fixing is on axle sleeve.
2. the described axle set of root a tree name claim 1 is characterized in that: be free-running fit between described axle sleeve and the wheel shaft, and stop pin is installed betwixt.
3. axle set according to claim 1 and 2 is characterized in that: described wheel shaft end is provided with and is used for the cannelure of installation shaft to the location collar, and the anti-slow gland by bolt is installed on wheel axle end surface.
