Abstract
The present invention relates to a kind of new guide wheel.The present invention sets wear ring between spoke and wheel rim, adds abrasive resistance.Solve the problems, such as that different zones difference is hardened requirement using the assembled welding of polylith simultaneously.The forging welding that guide wheel is changed to unlike material by the present invention by monoblock cast is made, integral quenching is carried out after machining, it make use of the characteristics of degree of hardening of different materials is with quenching degree difference, local heat treatmet is changed to bulk heat treatmet, reduce production cost, technique is simplified, improves product quality, extends the service life of guide wheel.
Description
Technical field
The present invention relates to a kind of new guide wheel, more particularly to vehicle track guide wheel, more particularly to different hardness
Polylith metal split guide wheel, belong to machinery manufacturing technology field.
Background technology
Known track guide wheels are cast with low-alloy steel, to carry out office in position easy to wear after thermally treated and machining
Portion's Surface heat-treatent forms, and because Surface heat-treatent is not easy to grasp, once processing is bad, can exist on the circumference at position easy to wear
, the soft ribbons of local soft be present, cause early stage excessive wear, make the guide wheel longevity in hardness and the uneven phenomenon of depth of hardening zone
Life shortens.
The content of the invention
To solve the problems, such as that track guide wheels hardness and depth of hardening zone are uneven in the prior art, cause the lost of life,
The present invention proposes a kind of new guide wheel.
The present invention is realized using following technical scheme：A kind of new guide wheel, including it is wheel hub, wheel rim, disc, wear-resisting
Ring, connecting tube, wheel hub are arranged on the center of guide wheel, and wheel rim is arranged on the outer rim of guide wheel；The both sides of wheel rim are respectively set vertically
There is a wear ring, the both ends of wheel hub are radially respectively provided with a discoid disc；The endoporus of disc intersects and welded with the outside of wheel hub,
Outer rim intersects and welded with the outer edge of wear ring；The endoporus of wear ring intersects and welded with the side of wheel rim；The wear ring
Planar circular and round platform annulus two parts are bent into, planar circular is outer shroud；A certain circumference in the middle part of the disc is provided with more
The hole of the individual double plates of insertion, coordinate in the hole and be provided with connecting tube, and welded between connecting tube and two disc.
The forging welding that guide wheel is changed to unlike material by the present invention by monoblock cast is made, and integral quenching is carried out after machining
Fire, the characteristics of degree of hardening of different materials is with quenching degree difference is make use of, local heat treatmet is changed to bulk heat treatmet, reduced
Production cost, technique is simplified, improve product quality, extend the service life of guide wheel.
Further, wear ring is made of high-carbon steel, enhances the rub proofness at present invention position easy to wear.
Preferably, wheel hub, wheel rim, connecting tube, disc are made of ordinary low-carbon steel or low-carbon alloy steel, with wear-resisting boxing
Rear integral quenching is connect, realizes the purpose for preferably extending guide wheel service life.
Brief description of the drawings
Accompanying drawing is broken section structural representation of the present invention；
In accompanying drawing, 1 it is wheel hub, 2 is disc, 3 is wheel rim, 4 is wear ring, 5 connecting tubes.
Embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail.
The present embodiment is welded by wheel hub 1, wear ring 4, wheel rim 3, disc 5, and wear ring 4 uses high-carbon steel wear-resistant material
Make, other positions use ordinary low-carbon steel or low-carbon alloy steel.As illustrated, disc 2 is made up of two pieces of disc plates, in disc
2 middle part is provided with the hole of multiple insertion two sides disc 2, and the connecting tube 5 being adapted to hole size, the both ends of connecting tube 5 are provided with hole
Plane is mutually passed through with the medial plane of disc 2, and is welded between connecting tube 5 and disc 2.Connecting tube 5 connect and be supported on two disc 2 it
Between, enhance the stability and intensity of disc 2.The setting that the exterior design of disc 2 increases wear ring 4 into bell mouth shape is empty
Between.Wear ring 4 is made up of planar circular and round table-like annulus, is realized running midplane annulus and is contacted with Heisei on track
Friction, the lateral surface of round platform annulus and the side of track rub；Therefore wear ring 4 is improved resistance to using the high quenching hardness of high-carbon steel
Bull ring semi-finals degree, increases the service life.The method that split type splicing is used in the present invention, piecemeal can be achieved machine is entered to different piece
Tool processing and heat treatment, hereby it is ensured that guide wheel different parts use different materials and the purpose of different requirements.So as to realize
Reduce the cost, improve the purpose of service life.
