Abstract

The utility mode discloses a mining car wheel set, which consists of a rim (2), a wheel spoke set, and a wheel hub (3). Wherein, the wheel spoke set is a group of arc shaped rib tendons (4) that are evenly distributed on the circumference direction and stretch along the radial direction. Resulting from that the arc shaped rib tendons have the extending or shrinking change surplus, the reacting force can be removed or reduced without causing any reacting concentration, and thus prolonging the application lifetime of the wheel set.

Description

Tramcar wheel is right

Affiliated field:

The utility model relates generally to the device that a kind of mine is used, and particularly a kind of tramcar wheel is right.

Background technology:

In the mine, comprise colliery, Gypsum Mine, metallic ore through mine car carrying goods and materials commonly used, as coal, ore, spoil, slag etc., mine car generally orbits.To forming, wheel is to being installed on the axletree by vehicle frame, railway carriage, bindiny mechanism and wheel for mine car, and take turns right main effect be carrying and mine car can normally be moved in orbit, is the maximum of loading on the mine car, and the parts that service conditions is the poorest also are consumable accessorys.Tramcar wheel is to being generally foundry goods, and general wheel has the wheel hub circle of axis hole and the spoke of connection wheel rim and wheel hub and forms by wheel rim.The right spoke of tramcar wheel in the past is the rectilinear muscle structure of pulling, often connecting wheel rim and the bigger casting residual stress of wheel hub formation that has axis hole, thereby at this place's formation stress concentration, spoke is ruptured easily influences safety in production, increased productive costs, right structure is necessary therefore to improve tramcar wheel.

Technical scheme:

The purpose of this utility model then is to provide one and has less casting stress, thereby the tramcar wheel that increases spoke service life is right.

For achieving the above object, scheme of the present utility model is: a kind of tramcar wheel of, wheel hub being made of wheel rim, spoke is right, and its spoke is to being one group of arc rib that radially extends uniform on the Zhou Fangxiang of garden.

Spoke is to being the arc rib, the shrink stress or the elongation stress that are produced by spoke are absorbed by the arc rib, produce strain by the arc rib, because the arc rib has the variation surplus that elongates or shortens, therefore can make stress relieved or minimizing, can not produce stress concentration, thereby prolong and take turns right service life, realize the purpose of this utility model.

Below in conjunction with diagram and embodiment scheme is described in more detail.

Description of drawings:

Fig. 1 is the right installation site front elevation of tramcar wheel;

Fig. 2 is the lateral plan of Fig. 1;

Fig. 3 is the right front elevation of tramcar wheel;

Fig. 4 is the A-A cutaway view of Fig. 3.

The specific embodiment:

As Fig. 1 and Fig. 2 is the right scheme of installation of tramcar wheel, shown mine car by 2 wheels to (1), 1 vehicle frame, 1 railway carriage and bindiny mechanism form.Wheel is made by foundry goods (1).The wheel of Fig. 3 to front elevation in, wheel comprises wheel rim (2) to (1), and the wheel hub (3) of axis hole is arranged, and it is right to connect the spoke of wheel rim (2) and wheel hub (3).Known spoke is to being a rib that stretches, the application's spoke to be one group at the uniform arc rib (4) that radially extends of garden Zhou Fangxiang, the bending direction unanimity of described arc rib (4), the width that forms the cavity between the rib of two adjacent arcs (4) is more than a times or a times of rib width, the cross sectional shape of described arc rib is a criss-cross, have axis hole (5) on its wheel hub (3), be used for installing two antifriction-bearing boxs (6), and be drilled with filler port (7) so that be that two bearings refuel at wheel hub (3).On the end face of wheel hub (3), have three screw holes (8) so that end cap is installed.

Wheel rim (2) makes the wheel rim form that cooperates with rail.

Adopt the tramcar wheel of such scheme right, because it is rational in infrastructure, reduced widely by spoke to brought in the junction of spoke and wheel rim and the stress concentration of the junction of spoke and wheel hub, thereby spoke is lost being difficult for, through practice, its work life approximately is more than the right twice of the tramcar wheel of known technology, thereby safer, more economical.

In sum, the utility model is an actv..

Claims

1, a kind of tramcar wheel is right, it is characterized in that: a kind of tramcar wheel of, wheel hub (3) being made of wheel rim (2), spoke is right, and its spoke is to being one group of arc rib (4) that radially extends uniform on the Zhou Fangxiang of garden.

2, a kind of tramcar wheel according to claim 1 is right, it is characterized in that: the bending direction unanimity of arc rib (4).
