Abstract
The utility model relates to a mineral dumper steering rocker arm with an internally embedded shaft sleeve, which belongs to the technical field of the engineering machinery, comprises a pin shaft, a steering rocker arm, an oil cup, a shaft sleeve body and a lubricating hole arranged in the steering rocker arm, and further comprises internally embedded shaft sleeve lug bosses arranged at two ends of the shaft sleeve body, wherein the internally embedded shaft sleeve lug bosses have contact with the upper end face or the lower end face of the steering rocker arm; the outer wall surface of the shaft sleeve body has contact with the inner circular wall of the steering rocker arm; the outer wall surface of the pin shaft has contact with the inner wall surface of the shaft sleeve body; and the oil cup is installed at the position of the upper end of the lubricating hole. The advantages are that: the clearance between two shaft sleeve bodies is used as an oil path; the shaft sleeve and the pin shaft have large contact area; and much lubricating grease is stored; the steering system has better lubrication effect; the shaft sleeve lug bosses are additionally provided, thereby providing convenience for installation and location of the shaft sleeve; when the shaft sleeve lug bosses are dismounted, a special clamp is used for clamping the lower surfaces of the shaft sleeve lug bosses so that the shaft sleeve can be pulled out; the shaft sleeve lug bosses are convenient to dismount; the lubrication effect is good and the lubrication contact area is large after installation and use.
Description
Technical field
The utility model relates to a kind of quarry tipper pitman arm, specifically is a kind of quarry tipper pitman arm with embedded axle sleeve, belongs to technical field of engineering machinery.
Background technology
In the automobile steering system, embedded axle sleeve belongs to an important components.Axle sleeve generally is used for the connection of equipment motion; Its cylindrical and hole are interference fit; Endoporus and bearing pin are free-running fit, owing to add the weight of equipment self after the axle sleeve load, axle sleeve carries very big; And also can produce certain impact to axle sleeve in the course of the work, so bearing pin and axle sleeve are in heavy duty and certain impact are arranged and have under the relatively slow rotation condition and work.Therefore, bearing pin and axle sleeve need performance requriementss such as higher surface abrasion resistance property, heart portion obdurability.Axle sleeve in the steering swivel system also will have good lubricating property.
The embedded axle sleeve of existing pitman arm is a single-piece, and the centre has oil duct and aperture, has a circle inside groove in the center of symmetry position of axle sleeve; And symmetry has two apertures, this lubricating method, and the area of contact of axle sleeve and pitman arm is smaller; The area of contact of axle sleeve and bearing pin is smaller; And the grease that stores is fewer, for the large-scale mine dumping car of in the abominable occasion of operating modes such as coal yard, iron ore, working, possibly have the phenomenon of lack of lubrication; Influence normal steering operation, in some cases even can cause turning to the malfunctioning serious accident that causes.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of quarry tipper pitman arm with embedded axle sleeve, and it has characteristics such as easy for installation, that use is simple, install and use the back high lubricating effect, the lubricating contact area is big.
To achieve these goals, the technical scheme of the utility model employing is: a kind of quarry tipper pitman arm with embedded axle sleeve comprises bearing pin; Pitman arm, lubricating cup, axle sleeve main body; And be located at the lubricious hole in the pitman arm; Also comprise the embedded axle sleeve boss that is located at axle sleeve main body two ends, embedded axle sleeve boss contacts with the upper surface or the lower surface of pitman arm, and axle sleeve main body outside wall surface contacts with the pitman arm inner round wall; The bearing pin outside wall surface contacts with axle sleeve main body inner wall face, and lubricating cup is installed in lubricious hole upper end position.
Further, the axle sleeve main body has two;
Further, the slit between two axle sleeve main bodys is an oil duct.
The beneficial effect of the utility model is: so that the slit is as oil duct between two axle sleeve main bodys, the area of contact of axle sleeve and bearing pin is bigger, and the grease that stores is many, and the lubricant effect of steering swivel system is better; Set up the axle sleeve boss, be convenient to the installation and the location of axle sleeve, in the time of dismounting; Clamp axle sleeve boss lower surface with unit clamp, just can pull out axle sleeve, dismantle more convenient; And install simply, easy to use, install and use the back high lubricating effect, the lubricating contact area is big.
Description of drawings
Fig. 1 is the utility model generalized section.
Among the figure: 1, bearing pin, 21, the axle sleeve boss, 22, the axle sleeve main body, 3, pitman arm, 31, lubrication hole, 32, the slit, 6, lubricating cup.
The specific embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
As shown in Figure 1, a kind of quarry tipper pitman arm with embedded axle sleeve is by bearing pin 1; Pitman arm 3, lubricating cup 4, axle sleeve main body 22; And be located at the lubricious hole 31 in the pitman arm 3; The embedded axle sleeve boss 21 that is located at axle sleeve main body 22 two ends is formed, and embedded axle sleeve boss 21 contacts with the upper surface or the lower surface of pitman arm 3, and axle sleeve main body 22 outside wall surface contact with pitman arm 3 inner round wall; Bearing pin 1 outside wall surface contacts with axle sleeve main body 22 internal faces, and lubricating cup 6 is installed in lubricious hole 31 upper end positions.
Further, axle sleeve main body 22 has two;
Further, the slit 32 between two axle sleeve main bodys 22 is an oil duct, and the size of oil duct designs according to lubricating requirement.
Axle sleeve main body 22 is formed embedded axle sleeve with the axle sleeve boss 21 that is located on the axle sleeve main body 22, and two embedded axle sleeve symmetries are used, in the time of installation; Locate more conveniently, the upper surface or the lower surface of axle sleeve boss 21 lower surfaces and pitman arm 3 contact, and promptly are in place; Dismounting time,, stretch among the small gaps with unit clamp then earlier axle sleeve boss 21 and small gaps of pitman arm 3 perks; With the external force axle sleeve boss 21 that outwards stretches, just can remove axle sleeve, form slit 32 after the installation; Grease gets into the lubrication hole 31 of pitman arm 3 through lubricating cup 4; Get into above-mentioned slit 32 then, lubricated bearing pin 1 and embedded axle sleeve main body, thus reach high lubricating effect, purpose that the lubricating contact area is big.
