Description
Technical field
The present invention relates to a kind of novel crawler guide rail, belong to farm machinery parts technical field.
Background technology
Crawler belt is driven by driving wheel, round the flexible chain link of driving wheel, bearing wheed, inducer and carrier wheel.Be with tracked machine (such as reaper) to be generally provided with crawler belt guide rail, this crawler belt guide rail is placed in crawler belt guide groove, and is connected with machine chassis.Crawler belt guide rail is used for advising positive crawler belt on the one hand, play the guiding role, and guides crawler belt to change rotation direction up or down, thus machine is moved forward; Crawler belt displacement when can prevent on the other hand machine from turning to or rolling traveling, to come off, with the adhesive ability of the impregnability and crawler belt and ground that improve crawler belt.
Crawler belt guide rail is generally made up of the guide be arranged in crawler belt guide groove, the mount pad that is connected with machine chassis.Existing crawler belt guide rail adopts casting mostly, one-body molded, costly; And the requirement of existing crawler belt guide rail material out of reach, not wear-resisting, service life is short, and after Long-Time Service, crawler belt guide rail easy to wear with crawler belt contact position (i.e. guide), but when changing accessory, need change whole crawler belt guide rail, and waste resource, increases cost.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of long service life, easy to wear, not cost-saving novel crawler guide rail are provided.
Content of the present invention is achieved through the following technical solutions: a kind of novel crawler guide rail, comprise the strip guide be placed in crawler belt guide groove, this guide top is provided with two mount pads be connected with machine chassis, it is characterized in that, mounting base is provided with bottom described mount pad, mounting base is provided with tapped bore, and guide top is being provided with threaded connection hole with tapped bore corresponding position, is threaded by mount pad with bolt successively precession tapped bore, threaded connection hole with guide.
Described mounting base is being provided with position-limited trough with guide contacts place, and described guide is being provided with position-limited trough corresponding position the spacing block set matched with it, and spacing block set is placed in position-limited trough.
Left side bottom described guide is faced upward curved, and its radian is 5 °-10 °.
Described guide left end end is provided with the gradient, and its gradient is 5 °-20 °, and the acclive end of this band is connected with the curved bottom transition of facing upward.
Described mount pad adopts cast molding.
Described guide adopts alloy material to make.
Described mount pad is provided with the connecting bore be connected with machine chassis.
The present invention changes original mount pad, the integrated structure of guide, mount pad is threaded integral with guide, treat that the work of crawler belt guide rail is of a specified duration, when guide wearing and tearing need to change, only need unthread bolts, change and crawler belt Long Term Contact and the guide that weares and teares, original mount pad is without the need to replacing, reusable, save cost.
Simultaneously, also be connected by the spacing block set (key) be arranged on the position-limited trough (keyway) at mounting base place, guide between mount pad with guide, spacing block set is placed in position-limited trough, this connection structure (key connection) contributes to the fastness be connected between mount pad with guide, when crawler belt guide rail can be prevented to be subject to lateral force, the phenomenon that bolt fractures, also can eliminate other harmful effects that crawler belt guide rail brings because of lateral force.
In addition, use the guide contacted with crawler belt instead alloy material in the present invention, this material is better than material of casting, more wear-resisting, extends the service life of crawler belt guide rail.
In the present invention, left side bottom guide is faced upward curved, its radian is 5 °-10 °, and guide left end end is provided with the gradient, its gradient is 5 °-20 °, be connected with the curved bottom transition of facing upward with acclive end, the place of facing upward and the gradient are disposed and are changed rotation direction place in crawler belt, are convenient to guide crawler belt to change rotation direction.Above structure design contributes to advising positive crawler belt, and the setting of two angular ranges is more conducive to guiding crawler belt to change rotation direction up or down, thus machine is moved forward; On the other hand, crawler belt skidding displacement or come off when this structure also can better prevent machine from turning to or rolling traveling, improves the impregnability of crawler belt and the adhesive ability on crawler belt and ground.
The present invention is simple and reasonable, and manufacture easily, easy accessibility, reduces cost, and result of use is good, wear-resisting, extends service life, improves work efficiency.
