Abstract
The utility model is a wheel band pre-installation used snap ring, aiming at the step arc surface and the opening part size that can influence the axial elasticity of the snap ring, the innovation is performed. The elasticity parameter at diameter direction of the snap ring can be increased; the buckle installation tightness degree between the snap ring and the wheel core is increased. The wheel band pre-installation used snap ring is wholly buckle installed in the groove of the wheel band relative to the rail car wheel. The snap ring is a ring with opening part, the inside of the ring is arranged with a circle of step which is used to buckle the wheel core, and the surface of the step has downward inclined arc shape. The angle of the step inclined plane of the snap ring is 5 degree to 8 degree. The opening part space distance of the snap ring is from 20mm to 40mm.
Description
Technical field
The utility model relates to the rim prepackage of using when a kind of wheel that is used for rail locomotive is assembled and uses snap ring, belongs to mechanical manufacturing field.
Background technique
The rail vehicle that comes into operation at present, as train, urban light rail and subway etc., its bogie is a fixing right rigid frame of front and back wheels, and wheel is to needing when the assembling earlier the rim hot charging on core wheel, then by with the clasp spiral-lock on the rim to realize the axially locating between clasp and the core wheel.
The snap ring of existing rim prepackage usefulness, after spiral-lock arrives the groove of rim, the elasticity deficiency of snap ring on its diametric(al), thus cause snap ring in groove, to be easy to rotate and upper and lower play, so snap ring is for the axially locating poor-performing of core wheel.
The model utility content
Snap ring use in rim described in the utility model prepackage, be to address the above problem and at the step cambered surface that influences its radial elastic surperficial and opening portion size improved.
Purpose of design of the present utility model is, strengthens the elastic parameter of snap ring on its diametric(al), improves the spiral-lock tightness degree between snap ring and the core wheel.
For realizing above-mentioned purpose of design, described rim is pre-installed and is used snap ring, and its whole spiral-lock is in the groove of the right rim of rail vehicle wheel.
Improvements of the present utility model are, snap ring is one to have the annular solid of opening portion, and the inboard of annular solid is provided with the step that a circle is used to withhold core wheel, and ledge surface has downward-sloping arc shape.
As above-mentioned scheme feature, have the circumferential clasp of opening portion, after the step of its declivity cambered surface and the core wheel spiral-lock, be easier to realize fitting tightly between snap ring and the core wheel, thereby improve the axially locating ability of wheel effectively inner snap ring.
Further improvement project is that the angle on the step inclined-plane of described snap ring is between 5 ° to 8 °.
The opening portion span of described snap ring is between 20 to 40 millimeters.
As above content, the advantage that described rim prepackage has with snap ring be, can improve the elastic parameter of snap ring on its diametric(al), and the spiral-lock between snap ring and the core wheel is tightr, avoids snap ring to rotate in groove and upper and lower play.
Description of drawings
Fig. 1 is that the wheel of described rail vehicle is to generalized section;
Fig. 2 is the I portion structure for amplifying schematic representation among Fig. 1;
Fig. 3 is the structural drawing of described snap ring;
Fig. 4 is that A-A among Fig. 3 is to sectional drawing.
As shown in Figures 1 to 4, rim 1, groove 2, snap ring 3, opening portion 4, step 5, declivity cambered surface 6, core wheel 7.
Embodiment
Snap ring 3 has the annular solid of an opening portion 4, and its opening portion span is between 20 to 40 millimeters.
The annular solid inboard of snap ring 3 is provided with a circle step 5, and step 5 surfaces have downward-sloping arc shape, and declivity cambered surface angle is 7 °.
