Abstract
The utility model provides a speed-raising turnout locking frame rolling device which belongs to the technical field of railway turnout and mainly solves the problem that since the roller shaft in the prior art is structured to be stepped, the grease hole penetrates axially the roller shaft and the oil outlet is provided in the middle of the shaft, the roller shaft is easy to break along the oil outlet, resulting in turnout failure and danger to railway safety. The utility model is characterized in that the device comprises a roller shaft, a roller wheel arranged on the roller shaft and a fastening screw, wherein the roller shaft is a solid cylindrical shaft with smooth surface; and the roller wheel is provided therein with a greased slide bearing. The utility model has the advantages of simple structure, large bearing capacity, and stable and reliable performance; and is mainly used for the external locking frame of railway speed-raising turnout.
Description
Technical field
The utility model belongs to the railway switch technical field, is specifically related to the tourelle in a kind of acclerating road switch locking frame.
Background technology
The tourelle of existing railway speed increase switch locking frame such as GSB-5 type locking frame is by the axis of rolling, roller, fixedly spacer and jam nut constitute.One end of the axis of rolling has the retaining cap, and the axis body that is close to this retaining cap partly is the step axle; Axis body centre portion diameter is 16 millimeters, is set with roller; The axis body other end is provided with screw thread, which is provided with fixedly spacer, the jam nut of fixed idler whell.Include two antifriction-bearing boxs and two oil sealings in the roller.The axis of rolling is provided with the butter hole of perforation along the axle center, and is provided with oil outlet at the axis body middle part.Because the butter hole intersects with oil outlet and communicates, to add in the middle part of the axis body carefullyyer, it is bigger that roller bears pressure, acts in the middle part of the axis body by a way of contact, thereby in use often cause the axis of rolling to rupture along oil outlet, causes switch breakdown, jeopardizes traffic safety.In addition, because jam nut is common six square nuts, thereby there is caducous problem.
Summary of the invention
The purpose of this utility model be exactly to provide at above-mentioned weak point a kind of simple in structure, bear that pressure is big, stable and reliable operation acclerating road switch locking frame tourelle.
Technical solution of the present utility model is: a kind of acclerating road switch locking frame tourelle, and comprise the axis of rolling, be contained in roller and jam nut on the axis of rolling, it is characterized in that: the described axis of rolling is solid cylinder light over glaze; Be provided with oil-containing sliding bearing in the roller.
Oil-containing sliding bearing described in the technical solution of the present utility model is two, and symmetry is set in the roller.
The diameter of the axis of rolling described in the technical solution of the present utility model is 25 millimeters.
Jam nut described in the technical solution of the present utility model is the hatch lock jack panel.
The utility model is owing to adopt the solid column type light face axis of rolling and the roller of interior oil-containing sliding bearing, thereby can avoid on the axis of rolling, establishing butter hole and oil outlet, and make the corresponding increasing of axis of rolling diameter, the pressure of roller acts on roller shaft with the face way of contact, therefore, the axis of rolling has bigger bearing pressure.Since adopt oil-containing sliding bearing in the roller, can be non-maintaining, reduced maintaining work.In addition, owing to adopt the hatch lock jack panel, thereby can make locking effect better, difficult drop-off, safe and reliable.The utlity model has simple in structure, bear the big and stable and reliable operation characteristics of pressure, be mainly used in the tourelle of the outer locking frame of railway speed increase track switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1.Locking frame 1 is existing acclerating road switch locking frame.The left end of the axis of rolling 2 is identical with the left end of existing axis of rolling retaining cap.The axis body of the axis of rolling 2 is solid cylinder type, smooth surface, and diameter is 25 millimeters.Hatch lock jack panel 6 is used for the axis of rolling 2, roller 3 are fixed on locking frame 1, its inboard is provided with plain cushion, spring chair 5, the oil-containing sliding bearing 4 that opening part is provided with 7, two symmetries of spring cotter is set in the inner ring of roller 3, and face contacts between oil-containing sliding bearing 4 and the axis of rolling 2.Actual detected, it is bigger that the axis of rolling 2 bears pressure, can guarantee effectively that it in use can not rupture.
